New minor risk - Share price stability The company's share price has been volatile over the past 3 months. It is more volatile than 75% of Australian stocks, typically moving 13% a week. This is considered a minor risk. Share price volatility indicates the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. It also increases the risk of potential losses in the short term as the stock tends to have larger drops in price more frequently than other stocks. Currently, the following risks have been identified for the company: Major Risks Earnings have declined by 35% per year over the past 5 years. Shareholders have been substantially diluted in the past year (45% increase in shares outstanding). Revenue is less than US$1m (AU$115k revenue, or US$81k).

New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 54% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings.

Great Boulder Resources Limited Announces Extensive New Gold Targets Discovered At Side Well Great Boulder Resources Limited provided an update on exploration activity within the Company's flagship Side Well Gold Project ("Side Well") near Meekatharra in Western Australia which hosts a Mineral Resource Estimate ("MRE") of 668,000oz @ 2.8 g/t Au. Auger sampling was completed across seven tenements within the Wanbanna joint venture area in which GBR acquired an interest in September 2024. Initial sampling was done at 50m spacing on east-west lines 400m apart, with subsequent infill sampling completed on 200m-spaced lines within areas of interest. The auger assays defined several large, high-tenor gold anomalies across the tenement package up to 1.8km long with gold values ranging from 5ppb Au to more than 1,000ppb (1g/t) Au.
This level of gold anomalism is unusually high in the Meekatharra area, where the presence of a shallow near-surface layer known as the Wiluna Hardpan acts as an impervious barrier limiting the upward mobility of gold during weathering and groundwater circulation. The area has been partly cleared by a heritage survey in early March, with a second survey planned to clear the remaining targets during the June quarter. Significant historical prospecting activity has occurred within the area, indicating strong surface gold mineralisation. Due to the tenure having been held by prospectors for many years there has been limited drilling over these targets. New Risk • Mar 12

Great Boulder Resources Announces Highly Prospective Wellington Tenure Granted ("Wellington") in the Earaheedy Basin of Western Australia have now been granted. Exploration licences E53/2242, E53/2243, E38/3751 and E38/3752 were granted in late January and early February following completion of the mandatory Native Title objection period. As the Company has an Aboriginal Heritage and land access agreement with TMPAC there were no objections lodged. Great Boulder and TMPAC are now working with DMIRS to have the remaining tenement E38/3622 granted as soon as possible. Great Boulder intends to commence exploration with a regional soil sampling program. Pending the availability of TMPAC heritage monitors, this is planned to commence in late March or early April. Great Boulder's Wellington Zn-Pb project was initially identified as a large-scale geochemical pathfinder anomaly during desktop analysis of open-file Government soil sampling data. There has been no previous Zn-Pb exploration in this area. Exploration by Rumble Resources Ltd. and Strickland Metals Ltd. suggest the Earaheedy has potential to become a world-class base metals province. Bekanntmachung • Jan 24
Great Boulder Resources Limited Launches 2023 Exploration Program Great Boulder Resources provided an update on recent exploration activity at the Side Well Gold Project near Meekatharra and the Whiteheads Project near Kalgoorlie in Western Australia. Side Well Gold Project: During November and December GBR's geologists completed a large-scale mapping exercise over the south-eastern area of Side Well with the aim of improving the Company's understanding of the stratigraphic and structural framework of that part of the Polelle Syncline. While mapping was underway the team also sampled any available bottom-of-hole chips from historic drilling within the mapping area in order to collate surface observations with lithogeochemical data. Once all assays are received and collated the combined mapping project will provide a greatly improved understanding of the local and regional geology, age relationships and possible thrust structures, all of which will assist with ongoing exploration targeting in the area. A program of 355 auger samples has been completed in the Ironbark North area. This program infills previous GBR auger sampling from 400 by 50m spacing to 200 by 50m to provide improved definition of geochemical anomalies int the area. Next Steps: A maiden Mineral Resource Estimate (MRE) is being prepared by an external consultant using all drilling and geological information collected from Mulga Bill and Ironbark. The purpose of the resource is two-fold, and it will: 1. Quantify the high-grade gold mineralisation defined by Great Boulder's drilling over the past two years at Side Well; and 2. Demonstrate the broader potential of the project. The MRE is expected to be ready within the next four weeks, with resource estimation workstreams now well advanced. Challenge Drilling will return to site to recommence RC drilling at Ironbark and Mulga Bill in the first week of February to follow up growth opportunities highlighted by the MRE. Whiteheads Project: A program of 416 soil samples has been completed at the Painkiller and nearby Leachers prospects during January, sampling the ferruginous horizon for potential base metals anomalism. Assays are expected in mid to late March and will be used to define and prioritise targets for follow-up exploration programs. Bekanntmachung • Dec 09
Great Boulder Resources Limited Provides an Update on Recent Exploration Activity At the Side Well Gold Project Great Boulder Resources Limited provided an update on recent exploration activity at the Side Well Gold Project near Meekatharra in Western Australia. RC Drilling: Results have been received from drilling at Mulga Bill (12 holes) and Ironbark (9 holes) up to the end of October. Significant results include: 8m @ 6.51g/t from 96m, including 4m @ 11.85g/t from 96m, in 22MBRC094 within the recently discovered eastern high-grade zone at Mulga Bill; 24m @ 1.19g/t Au from 68m, including 8m @ 2.76g/t Au from 76m in 22IBRC039 at Ironbark; 4m @ 1.15g/t Au from surface in 22IBRC043 at Ironbark. These results represent the final round of RC drilling at Side Well, as the rig has demobilised from site to give the field team time to complete mapping, interpretation of results, preparation of mineralisation wireframes and additional auger sampling prior to the next round of drilling. Ironbark South: pathfinder anomalism over 12km of strike: On 28 September 2022 GBR announced a series of new exploration targets in the area between Ironbark and the southern tenement boundary. This outcome represents a significant breakthrough in the Company's regional exploration program as the new targets highlight the potential scale of gold mineralisation along the eastern limb of the syncline, comparable in strike extent to the Paddy's Flat gold camp hosted on the western limb. GBR has now completed infill auger sampling over the Ironbark South grid, with over 1,300 auger samples collected at a 200 x 50m grid cell size. The additional data density has confirmed and refined the new targets, which will be tested by air-core (AC) drilling in 2023. Analysis of the auger data by Dr Scott Halley provides some extremely significant conclusions relevant to the regional mineral system at Side Well, including: The monzogranite abutting the greenstones east of Ironbark South appears to be the source of mineralising fluids, with a strong temperature gradient of pathfinder elements moving away from the granite contact into the mafic/ultramafic package. Mo is strongest on the granite contact followed by very high Bi with arsenic (As) anomalism and then antimony (Sb) further west into the mafic and ultramafic rocks that surround the granite. This is a zoning pattern that is typical of temperature gradients formed around mineralized intrusions in all sorts of geological settings. The presence of broad pathfinder anomalism together with Au, As and some Cu suggests Side Well is a large-scale hydrothermal camp. The scale of the anomalism over 12km is now equivalent to the strike extent of the Meekatharra camp. This hypothesis explains both the intrusive-related characteristics of Mulga Bill and the orogenic style of Ironbark, which is likely to represent remobilisation of mineralising fluids into a ductile environment inboard from the granite contact. This interpretation of the Side Well mineral system expands the Company's search radius even further. Ironbark South rock chip samples up to 7.34g/t Au: During October rock chip samples were taken during field reconnaissance at Ironbark South. Two samples taken from a cluster of shallow historic workings approximately 1.5km from the southern tenement boundary include smoky quartz material assaying 7.34g/t Au. The significance of this is twofold: firstly, it confirms the presence of high-grade gold-bearing structures at Ironbark South (as indicated by the auger geochemistry); and secondly it confirms gold close to surface. The latter observation is based on the fact that the shafts from which the quartz sample originated are less than 10m deep. Next Steps: Great Boulder's field team has commenced geological mapping of structure and stratigraphy from Ironbark to the southern tenement boundary to improve the Company's understanding of the Polelle Syncline. This mapping will assist in prioritising new areas for further exploration. The team will also start mapping north from Ironbark in an ongoing program, as time permits. Regional auger sampling over the eastern stratigraphy, including the area north of Ironbark, will continue to infill the previous 400 x 50m grid to 200 x 50m coverage. The geological team is also working to incorporate recent drilling results into the mineralisation models for Mulga Bill and Ironbark in order to update and refine wireframes of all mineralisation defined to date. These wireframes will be used as the basis for a maiden Mineral Resource Estimate that the Company is aiming to finalise during First Quarter of 2023. Board Change • Nov 16

Great Boulder Resources Limited Announces High Grade Results Continue At Mulga Bill Great Boulder Resources Limited announced and updated of drilling results at the Side Well Gold Project near Meekatharra in Western Australia. Results have been received from a series of holes drilled at Mulga Bill during August and September. Drilling was conducted at both the High Grade Vein (HGV) area in the north and the Primary Zone in the centre of the Mulga Bill prospect. Significant results include: · 13m @ 25.50g/t from 96m, including 4m @ 76.90g/t from 100m, and 5m @ 8.65g/t from 182m including 1m @ 35.40g/t from 183m in 22MBRC061 (HGV area) · 10m @ 28.74g/t from 96m, including 4m @ 29.4g/t from 96m and 1m @ 121.00g/t from 101m in 22MBRC067 (Central Zone) · 14m @ 5.22g/t from 92m, including 4m @ 7.56g/t from 96m and 2m @ 20.47g/t from 102m in 22MBRC069 (Central Zone) · 36m @ 1.17g/t from 100m in 22MBRC075 (HGV area) · 22m @ 1.27g/t from 228m, including 4m @ 4.33g/t from 246m, in 22MBRC076 (HGV area) · 4m @ 6.33g/t from 204m, including 2m @ 12.10g/t from 204m, and 8m @ 2.49g/t from 252m, including 1m @ 17.05g/t from 259m, in 22MBRC082 (HGV area) · 36m @ 1.22g/t from 238m, including 8m @ 2.46g/t from 262m, in 22MBRC084 (HGV area) The drillholes returned from the Central Zone represent some of the highest grade intersections at Mulga Bill outside of the HGV area. These intersections occur proximal to the fresh rock boundary and some supergene enrichment of gold may be present, however fresh quartz veining is associated with the intervals suggesting a primary source. This source may be a shallow west-dipping high grade vein similar to those encountered further to the north at Mulga Bill. These holes were drilled into the Cu-Au-Ag zone (Central Zone) with multi-element analyses to be returned in the coming months. Drilling has confirmed the orientation and continuity of the new lode discovered in the previous phase of drilling (see ASX announcement dated 29/09/22) east of the HGV area. This lode appears to be a similar shallow dipping orientation to the main high grade vein hosting significant gold to the west. This new mineralised structure remains completely untested along strike and at depth, and will be a focus for further exploration. The main high grade vein structure has been extended 30m to the north by drillhole 22MBRC075 and mineralisation is now trending into an area that remains untested by RC drilling. A post- mineralisation dyke cuts through this area however drilling will need to be undertaken to the north of this dyke to test for the continuation of mineralisation. Results from the fourth phase of regional aircore drilling have been received. Holes were drilled at Ironbark and Loaded Dog, with 2 free holes drilled by the contractor at Flagpole to test the rig configuration. Significant results include: · 8m @ 1.02g/t from 48m in hole 22SWAC264 (Loaded Dog) · 20m @ 1.07g/t from 16m in 22SWAC265 (Loaded Dog) · 4m @ 4.24g/t from 108m in 22SWAC316 (Flagpole) Gold anomalism at Loaded dog now defines a 900m plus zone within the regolith profile (Figure 5) with gold occurring at a shallow depth in some areas. Further RC drilling is needed at this prospect to test the extent and orientation of primary mineralised structures. Drilling at Flagpole has added to the geological confidence that high grade gold is hosted in shallow west-dipping vein sets similar to those seen at Mulga Bill. Drilling to the west, east and south of Ironbark did not return any significant gold mineralisation however pathfinder anomalism highlights the continuation of the structure thought to be controlling the gold at Ironbark. RC drilling is ongoing, with a further fourth phase of RC drilling at Ironbark now complete. At Ironbark South, drilling operations are now paused while the latest results are evaluated, and reconnaissance work is completed. Bekanntmachung • Oct 21
Great Boulder Resources Provides an Update on Recent Drilling Programs at the Side Well Gold Project ("Side Well") Near Meekatharra Great Boulder Resources provided an update on recent drilling programs at the Side Well Gold Project ("Side Well") near Meekatharra. Assays have been received for the Phase 3 RC program drilled at Ironbark in early July. Drilling was designed to test strike and depth extensions of mineralisation and infill areas where previous drilling had missed interpreted lodes. Results received include: 15m @ 1.99g/t Au from 37m in 22IBRC022. 5m @ 51.65g/t Au from 106m, including 1m @ 193.50g/t Au from 107m in 22IBRC024. 8m @ 4.31g/t Au from 88m and 5m @ 6.10g/t Au from 122m in 22IBRC025. 2m @ 13.76g/t Au from 133m, including 1m @ 26.70g/t Au from 133m in 22IBRC027. 3m @ 27.06g/t Au from 145m, including 1m @ 79.80g/t Au from 147m in 22IBRC028. 22m @ 1.43g/t Au from 102m, including 2m @ 13.57g/t Au from 102m in 22IBRC029. The third phase of RC drilling at Ironbark has successfully intersected the higher gold grades yet seen at the prospect. These intersections highlight the potential for high grade plunges within the wider mineralised zones. Drilling has successfully confirmed mineralisation within parallel steeply west-dipping lodes located on or around the contacts between mafic and ultramafic rock units. The third phase of drilling has also extended the strike of Ironbark to over 500m. The most northern RC drillhole at the prospect, 22IBRC022, returned an intersection of 15m @ 1.99g/t at shallow depths and further drilling is being planned in this area. AC drilling immediately south of Ironbark has recently been completed to test southerly strike extensions, with results anticipated in the coming weeks. Bekanntmachung • Sep 30
Great Boulder Resources Announces New High-Grade Gold Lode Identified at Mulga Bill Great Boulder Resources announced the balance of results from Mulga Bill Phase 3 and Phase 4 RC drilling at the Side Well Gold Project ("Side Well") near Meekatharra in Western Australia. Results from RC drilling recently completed at Mulga Bill have returned significant intersections including: 8m at 5.51g/t Au from 110m and 6m at 25.83g/t Au from 268m in hole 22MBRC055. The deeper intersection in this hole is interpreted to represent a new high-grade lode in fresh rock approximately 90 to 100m east of previous high-grade intersections; 8m at 54.60g/t Au from 120m in 22MBRC056; 6m at 4.59g/t Au from 94m, including 2m at 10.25g/t Au from 94m and 5m at 5.83g/t Au from 113m in hole 22MBRC046; 3m at 7.03g/t Au from 101m in 22MBRC048; 1m at 29.40g/t Au from 103m and 1m at 21.10g/t Au from 124m in 22MBRC052; 1m at 21.10g/t Au from 156m in 22MBRC059 at Mulga Bill North. AC drilling has been completed at a number of target areas between Mulga Bill and Ironbark, with results expected in the next four to six weeks. RC drilling is ongoing, with further work planned at Flagpole in addition to ongoing Mulga Bill drilling. Results from the third phase of RC drilling at Ironbark are expected in the next one to two weeks. Bekanntmachung • Sep 29
Great Boulder Resources Limited Announces Gold Potential South of Ironbark Confirmed by Auger Sampling Great Boulder Resources announce geochemical results from recent auger sampling at the Side Well Gold Project ("Side Well") near Meekatharra in Western Australia. Auger sampling along 7km of prospective strike south of the Ironbark gold discovery has confirmed the exploration potential of this previously untested area. A series of high-tenor gold anomalies have been defined within the same stratigraphy as Ironbark presenting multiple targets for drill testing. In addition, a 4km zone of coincident gold-bismuth anomalism centred over interpreted volcaniclastics was identified in the southern half of the auger grid displaying compelling similarities to the Mulga Bill style of mineralisation. Sampling is ongoing, with additional auger coverage infilling this to a 200 by 50m grid in selected areas. Infill sampling is based upon the observation that Ironbark is approximately 400m long. Gold anomalies were identified in multiple areas within the same mafic-ultramafic package as Ironbark. This package is the eastern equivalent of the unit that hosts many of the gold occurrences at Paddy's Flat on the western limb of the Polelle Syncline, yet it has not previously been explored.

Great Boulder Resources Announces New Drilling Results from the Side Well Gold Project Near Meekatharra in Western Australia Great Boulder Resources announced new drilling results from the Side Well Gold Project near Meekatharra in Western Australia. RC drilling into the high-grade vein area at the northern end of Mulga Bill intersected 15m @ 35.82g/t Au from 88m, including 6m @ 83.58g/t Au from 96m in hole 22MBRC038. This structure also hosts previous intersections of 5.9m @ 39.37g/t Au from 84.3m (22MBDD005, announced 7/7/22) and 6m @ 24.33g/t Au from 132m (21MBRC034, announced 2/9/21). The Company has received assay results for all holes drilled in the recent RC programs at Flagpole and Loaded Dog. In addition to these results the Company has received initial assays for 13 of 19 RC holes drilled during Mulga Bill Phase 3, and five of 23 holes in Mulga Bill Phase 4. Highlights include: 15m @ 35.82g/t Au from 88m including 6m @ 83.58g/t Au from 92m in 22MBRC038 at Mulga Bill. This includes 4m composite samples to 96m down-hole. 6m @ 5.52g/t Au from 80m including 4m @ 7.99g/t Au from 80m in the same vein in 22MBRC039 at Mulga Bill. This intersection approximately 25m north of 22MBRC038 extends high-grade vein-related mineralisation upwards into the deleted zone. 2m @ 52.00g/t Au from 128m in 22MBRC030 in the Eastern Zone at Mulga Bill. The high-grade vein (HGV) area in the north of the Mulga Bill is interpreted to contain a series of vein sets that sit within more felsic units of the stratigraphy. These north-south trending stratigraphic units have a width of between 50-100m and veins are developed either as flat-lying sets or west- dipping sets along with vertical mineralisation zones on lithological boundaries. The main HGV defined to date has a strike length of more than 130m with the new intersection from 22MBRC038 lying at the southernmost boundary of current modelling. The intersection in hole 22MBRC038 extends the high-grade vein further south by approximately 30 metres from previous drilling. This structure also contains previous high-grade intersections such as 5.9m @ 39.37g/t Au and 6m @ 24.33g/t Au, the latter of which is in the same hole as the project's highest-grade result: 14m @ 36.12g/t Au from 91m. The 22MBRC038 intersection sits within a moderately weathered quartz zone. There is potential supergene enrichment to contribute to the extremely high grades in the area. Assays are pending for the remaining 19 RC holes drilled in Phase 4, with all results expected by the end of September. The next phase of drilling is now being planned, including holes into the high-grade vein area as well as additional infill drilling on the less well-defined eastern zone. Recent drilling in this area is helping to define high-grade areas within the eastern zone, where more than 400 metres of mineralised strike remains poorly tested. The high-grade composite samples in hole 22MBRC038 have been re-split into 1m samples and submitted for assay, with results expected in four to five weeks. Flagpole: More RC drilling is being planned for the Flagpole prospect. With only five RC holes completed to date, the nature and orientation of high-grade mineralisation identified by AC hole 21SWAC119 (3m @ 8.56g/t Au including 1m @ 23.78g/t Au from 149m to EOH) is not yet understood. RC hole 22MBRC020 (3m @ 9.39g/t Au from 86m) appears to have intersected a separate mineralised structure to that seen in the original AC hole. To date RC drilling at Flagpole has defined significant intersections over 100 metres of strike and remains open to the north and south. This area is a priority for further drilling. Results from recent drilling are disappointing, with no high-grade intersections from five RC holes drilled during July. More AC drilling is planned in the area, and this drilling will be used to refine the geological interpretation prior to planning any further RC drilling. Phase 3 RC drilling is ongoing, with ten holes completed. The first assay results from this program are expected in late September. Once all the data has been compiled the Company will consider whether Ironbark mineralisation has been defined sufficiently for the estimation of an Inferred Mineral Resource. An AC rig will mobilise to site in September to complete infill drilling at Loaded Dog and Mulga Bill and to test geochemical anomalies immediately north of Ironbark. This reconnaissance drilling will be the first in the area since the Ironbark discovery was confirmed by AC drilling in May 2021. RC drilling will continue on all prospects in sequence. Metallurgical test-work on Ironbark RC chips is ongoing, with results expected in approximately four weeks. Bekanntmachung • Aug 24
Great Boulder Resources Provides an Update on Recent Drilling Programs At the Side Well Gold Project Great Boulder Resources provided an update on recent drilling programs at the Side Well Gold Project ("Side Well") near Meekatharra and the Whiteheads Project north of Kalgoorlie in Western Australia. Assays have been received for the remaining holes from the Phase 2 RC program drilled at Ironbarkin early July. The Company has also received results from ongoing RC programs at Flagpole (fourholes) and Mulga Bill (seven holes). Highlights include: 11m @ 7.31g/t Au from 46m, including 4m @ 15.27g/t Au from 47m in 22IBRC017 atIronbark; 28m @ 1.13g/t from 64m, including 8m @ 2.91g/t Au from 84m in 22IBRC013 at Ironbark; 4m @ 25.89g/t Au from 210m, including 2m @ 49.73g/t Au from 210m in 22MBRC022 at Mulga Bill; 1m @ 19.45g/t Au from 100m in 22MBRC025 at Mulga Bill; 3m @ 9.39g/t Au from 86m in 22MBRC020 at Flagpole; 4m @ 3.66g/t Au from 96m, including 2m @ 6.47g/t Au from 96m in 22MBRC021 at Flagpole. Mineralisation at Ironbark remains open along strike, particularly to the north where the previous drilling intersection of 20m @ 3.16g/t Au from 16m in hole 22IBRC014 remains the northern- most RC hole drilled at the prospect. Great Boulder have commenced a program of auger sampling south of Ironbark extending to thesouthern tenement boundary, a distance of approximately 7km over the same stratigraphy as hosts the Ironbark deposit. The sampling grid is on 50m spacing with lines 400m apart, the same as originally used to successfully identify the Ironbark anomaly. Initial results are expected within the next two months. Mulga Bill: The intersection in Mulga Bill hole 22MBRC022 (4m @ 25.89g/t Au from 210m) is located at the southern end of the central Mulga Bill high-grade area on the same northing as 21MBRC054, which intersected 9m @ 24.19g/t Au from 193m . While the high-grade gold mineralisation in hole 21MBRC054 is interpreted to sit within a sub-vertical structure the nearby intersection in 22MBRC022 is interpreted to sit within a flat-lying high-grade vein, in a similar style to the high-grade sub-horizontal vein intersections previously drilled at the northern end of Mulga Bill.

Great Boulder Resources Limited Provides Ironbark Drilling Update Great Boulder Resources provided an update on assay results from another two and a half RC holes from recent RC drilling at the Ironbark discovery at the Side Well Gold Project near Meekatharra in Western Australia. Assays have been received for an additional 2 ½ holes from the Phase 2 RC program drilled at Ironbark in early July. Highlights include: 20m @ 3.16g/t Au from 16m, including 8m @ 6.66g/t Au from 28m in 22IBRC014. Mineralisation remains open to the north, with hole 22IBRC014 the northern-most hole yet drilled at the prospect. Mineralisation is also open to the south, with assays yet to be received for drilling in that area. Because the Company has not yet had time to compile update cross sections these will be included in the next exploration update for Ironbark. Assays from the remaining 6 ½ RC holes in this phase of drilling are expected within the next two weeks. Bekanntmachung • Aug 02
Great Boulder Resources Announces Assay Results from the Second Phase of RC Drilling At Ironbark Discovery At the Side Well Gold Project Great Boulder Resources announce assay results from the second phase of RC drilling at the Ironbark discovery at the Side Well Gold Project near Meekatharra in Western Australia. Assays have been received for the first four holes of a nine-hole RC program drilled at Ironbark in early July. Highlights include: 32m @ 2.48g/t Au from 24m, including 20m @ 3.19g/t Au from 24m in 22IBRC008; 17m @ 5.81g/t Au from 120m, including 6m @ 7.38g/t Au from 120m and 6m @ 8.76g/t Au from 131m in 22IBRC003. The Company has also received assays for 1m re-split samples from Phase 1 RC intervals previously assayed in 4m composites. The 1m samples have refined and, in some cases, upgraded previously reported intersections. Highlights include: 12m @ 10.24g/t Au from 120m, including 4m @ 25.90g/t Au from 120m; and 1m @ 11.80g/t Au from 138m in 22IBRC003. This interval was previously reported as 20m @ 3.05g/t Au from 120m. 7m @ 8.44g/t Au from 107 including 1m @ 38.80g/t Au from 112m and 1m @ 2.72g/t Au from 117m in 22IBRC007. This interval was previously reported as 14m @ 4.25g/t Au from 104m.Other high-grade intersections in the Phase 1 RC program at Ironbark (e.g. 9m @ 4.49g/t Au from104m in 22IBRC003) have not changed as they were sampled at 1m intervals. Assays from the remaining nine RC holes in this phase of drilling are expected within the next two to three weeks. Next Steps A parcel of mineralised material from fresh RC intersections at Ironbark has been delivered to IMO Metallurgy in Perth for testing. This work will examine the metallurgical characteristics of the sample including gravity gold recovery at various grind sizes, cyanide consumption and overall gold recovery in leach testing. Final results are anticipated in approximately two months. RC drilling is progressing well on the Mulga Bill corridor, and a program of works (PoW) approval has been lodged for a third round of RC drilling at Ironbark. Once all Phase 2 assays have been received and the results interpreted the Company will re-assess priorities at Side Well, with an option to accelerate drilling at Ironbark in order to move towards a maiden Mineral Resource Estimate in the medium term. Greenfields Exploration: Ironbark was originally identified as a 2-point gold anomaly in auger sample data collected by GBR in late 2020. The success of this technique has sharpened the Company's focus on other similar targets in the mafic-ultramafic sequence on the eastern side of the greenstone belt, a stratigraphic position which is approximately equivalent to the location of the Paddy's Flat host rocks on the opposite side of the syncline. As part of an ongoing process of exploration target generation the Company has identified targets in the Ironbark area based upon geochemical data and litho-structural setting, including auger anomalies similar to the original Ironbark discovery holes. With over 7km of prospective strike south of Ironbark that remains completely untested, geochemical sampling followed by AC testing will commence in the current half year. Bekanntmachung • Jul 07
Great Boulder Resources Limited Announces High-Grade Intersection in Mulga Bill Diamond Drilling Great Boulder Resources announced assay results from the last two diamond holes drilled at Mulga Bill in April, as well as further assays from recent RC and AC drilling at Mulga Bill within the Side Well Gold Project ("Side Well") near Meekatharra in Western Australia. 21 AC holes remain to be reported, with results expected in the coming weeks. The AC results to date provide further encouragement within gaps in previous drill coverage along the 6km-long Mulga Bill footprint, with results such as 1m at 8.51g/t Au in 22SWAC175 and 4m at 1.16g/t Au in 22SWAC183 adding definition at Loaded Dog. Meanwhile the result in hole 22SWAC180 (4m at 1.63g/t Au) demonstrates potential for additional mineralisation further west, as this is the western- most hole on that line. RC drilling is currently making good progress at the southern end of the Mulga Bill corridor and at the nearby Ironbark prospect, with initial assays expected in August. Assay results from the 95-hole AC program completed at the Whiteheads Gold Project in June 2022 remain outstanding. With reference to the collaborative research project with Australia's national science agency, CSIRO in the ASX announcement of 7 December 2021, Dr. Walid Salama, a Senior Research Scientist at CSIRO Australian Resources Research Centre in Perth recently used a TESCAN TIMA scan on a sample of quartz vein showing visible gold from diamond hole 22MBDD002 to produce a map of mineral species within the sample. A sub-section of the scan displays a number of sulphide minerals attached to a grain of gold. As can be seen in the image there are five different bismuth minerals in the sample around the gold, three of which contain copper. This observation provides a clear explanation for the geochemical correlation between gold, bismuth and copper at Mulga Bill. Bekanntmachung • Jul 01
Great Boulder Resources Limited Announces RC Drilling Recommences At Side Well Great Boulder Resources provided an update on exploration activity at the Side Well Gold Project in Western Australia. RC drilling has recommenced at the southern end of Mulga Bill where AC drilling in late 2021 intersected an end-of-hole sample grading 23.78g/t Au. This area remains completely untested by RC drilling. The rig will also complete a second phase of RC drilling at the new Ironbark discovery, with extensional holes planned to test the strike extent of recent high-grade intersections announced earlier in June. Drilling is expected to continue for the remainder of the year as part of Great Boulder's strategy to advance the Mulga Bill deposit towards a maiden Mineral Resource estimate as quickly as possible.

Great Boulder Resources Announces Further Assay Results from the Maiden RC Program At the Ironbark Prospect as Well as Recent RC Assays from Mulga Bill, Both of Which Form Part of the Side Well Gold Project Near Meekatharra in Western Australia Great Boulder Resources announced further assay results from the maiden RC program at the Ironbark prospect as well as recent RC assays from Mulga Bill, both of which form part of the Side Well Gold Project ("Side Well") near Meekatharra in Western Australia. Assays have been received for the remaining RC holes drilled at the Ironbark discovery east of Mulga Bill. Highlights include: 9m @ 4.49g/t Au from 104m in 22IBRC003; 20m @ 3.05g/t Au from 120m in 22IBRC003; 3m @ 1.06g/t Au from 74m in 22IBRC001A; 3m @ 1.77g/t Au from 129m and 1m @ 6.85g/t Au from 137m in 22IBRC002. Highlights from recent drilling on the Mulga Bill Loaded Dog trend include: 4m @ 7.02g/t Au from 84m in 22MBRC012; 5m @ 8.67g/t Au from 114m in 22MBRC012; 1m @ 39.30g/t Au from 84m in 22MBRC003; 17m @ 1.39g/t Au from 151m to EOH (end of hole) in 22MBRC005; 1m @ 9.09g/t Au from 227m to EOH in 22MBRC009; 25m @ 1.34% Cu, 13.33g/t Ag and 0.41g/t Au from 88m, including 13m @ 2.01% Cu, 18.59g/t Ag and 0.36g/t Au from 88m within the "sulphide zone" in 22MBRC003. Mineralisation at Ironbark sits on lithological contacts between basalt and ultramafics and strikes north-northeast. The mineralisation appears to have a steep easterly dip, although more drilling is required to confirm this interpretation. The competency contrast between brittle basalt and relatively ductile ultramafics is a classic structural setting favourable for deposition from mineralising fluids. Additional drilling is required to provide confidence on the continuity and orientation of mineralised zones between drill sections, which are currently spaced 100m apart. Mineralisation has been defined over approximately 400m, and with the southern-most hole 22IBRC007 intersecting 14m @ 4.25g/t Au it remains open to the south. Importantly the interpreted orientation means the northern-most hole 22IBRC006 was drilled too far to the west, so Ironbark appears to be open along strike in both directions. While the copper intersection in hole 22MBRC003 clearly demonstrates the potential significance of this area the Company remains focused on testing high-grade gold mineralisation at Mulga Bill. The other results from this RC campaign continue to support the sub-vertical vein interpretation, which appears to be a later structural element cross-cutting sub-horizontal high-grade vein sets intersected in some of GBR's earlier RC programs. Ongoing drill programs will be selectively targeting these vein sets with a primary focus on defining continuity of high-grade gold zones. The large, subvertical and relatively tabular copper sulphide zone will also be drilled, but as a secondary priority. When RC drilling resumes at the end of June the first new target to be drilled will be at the southern end of the Mulga Bill Loaded Dog corridor, where an air-core hole ended in 23.78g/t Au mineralisation at 150m depth. An extensional and infill RC program will also be completed at Ironbark. Current coverage comprises only seven RC holes spanning 400m of strike. The next round of drilling will test continuity of mineralisation between the current intersections, test for strike extensions to the north and south and also test deeper targets beneath known intersections. The 57 AC holes currently being assayed include infill drilling over significant gaps in coverage north and south of Loaded Dog, some of which test the target area immediately east of the IP chargeability anomaly recently tested by diamond hole 21MBRCD096. End-of-hole gold and multi-element assays from these holes will be integral to planning further RC drill campaigns in the area in coming months. Bekanntmachung • Jun 14
Great Boulder Resources Limited Announces Initial Assay Results from the Maiden Rc Program At the Ironbark Prospect Within the Side Well Gold Project Great Boulder Resources Limited announce initial assay results from the maiden RC program at the Ironbark prospect within the Side Well Gold Project ("Side Well") near Meekatharra in Western Australia. Assays have been received for three of the seven holes drilled at the Ironbark discovery east ofMulga Bill. Highlights from these holes include: 22m @ 2.47g/t Au from 38m in 22IBRC005, including 4m @ 6.68g/t g/t Au from 39m; 14m @ 4.25g/t Au from 104m in 22IBRC007, including 8m @ 5.96g/t Au from 108m; 2m @ 1.33g/t Au from 128m in 22IBRC007. Geological logging of the RC chips indicates a zone of deeper weathering striking north-northeast through Ironbark, coincident with gold mineralisation. This observation together with the multi- element geochemistry suggests Ironbark is a structurally controlled orogenic system. The deeper weathering means these intersections are in partially weathered rock, but they are likely to relate to primary mineralization at depth. Assays for the remaining holes at Ironbark are expected in the coming weeks, and more drilling will be completed as part of the upcoming program expected to commence at the end of June.

Great Boulder Resources Limited Provides Update on Recent Exploration Activity at the Mulga Bill Prospect in Western Australia Great Boulder Resources Limited provided an update on recent exploration activity at the Mulga Bill prospect in the Side Well Gold Project in Western Australia. Following the announcement of initial results from the eight-hole diamond program at Mulga Bill1 assays have now been received for three more holes, including additional intersections of high-grade gold mineralization consistent with previous drilling. Highlights include: 2.0m @ 9.41g/t Au from 90m including 0.56m @ 30.80g/t Au in 22MBDD004. 0.57m @ 19.20g/t Au from 11.75m in 22MBDD004. 1.52m @ 5.93g/t Au from 148.6m in 22MBDD004. 0.43m @ 11.53g/t Au from 106.21m including 0.15m @ 30.50g/t Au in 22MBDD003. 0.33m @ 24.70g/t Au from 153.52m in 22MBDD003. The 450m-deep hole 21MBRCD096 drilled into a coincident gravity and electromagnetic (EM) anomaly at 7059500N failed to intersect any significant mineralization (Figure 2). Originally drilled as a 250m-deep RC hole, the 200m diamond tail intersected broad zones of disseminated pyrite returning assays of up to 3% sulphur. These elevated sulphur values are considered sufficient to explain the geophysical anomalies and subsequent chargeable zone generated by GBR's recent 3D-IP survey. Despite the lack of significant gold grades, zones of strongly elevated pathfinder geochemistry including 3.3m @ 14.01ppm Bi from 369.7m indicate that this area is proximal to gold mineralization. Further analysis of the recent 3D-IP data has revealed a broad zone of increased resistivity immediately east of the chargeable anomaly around 21MBRCD096. Previous drilling to the north suggests this position on the eastern edge of the chargeable zone is highly prospective for gold mineralization, and the interface between chargeable and resistive features may represent a lithological contact. As mentioned in previous GBR announcements the chargeable zone results from disseminated sulphides, mainly pyrite, while the resistive anomaly may be caused by alteration processes including silicification and sericitisation. The Company is still awaiting assays for diamond holes 22MBDD005 and 22MBDD007. 31 RC holes were drilled at Mulga Bill, Loaded Dog and Ironbark in April and May for a total of 4,922m. 57 AC holes were drilled at Mulga Bill during May and June for 5,719m. The AC rig has now moved to the Company's Whiteheads Gold Project north of Kalgoorlie to test a number of regional gold targets. Next Steps: Challenge Drilling are scheduled to return to Side Well at the end of June to commence RC drilling, with this rig to remain on site for the remainder of the year. One of the first priorities for RC drilling is the southern end of the Mulga Bill corridor, where AC hole 21MBAC119 intersected 3m @ 8.56g/t Au at the bottom of hole, including 1m @ 23.78g/t Au in the last meter of that hole This is an target in an area which remains completely untested by RC drilling. To put this target into context, the gold grade at the bottom of 21MBAC119 is of similar tenor to GBR's first high-grade intersection at Mulga Bill. Effectively the discovery hole for Great Boulder's exploration, 21MBAC022 intersected 3m @ 34.5g/t Au from 32m. This was the first high-grade intersection at Mulga Bill, subsequently leading to multiple intersections of extremely high-grade vein positions in the surrounding area. The ongoing RC program will also continue to test targets along the IP chargeability zone. This drilling will be designed to identify additional high-grade gold mineralization and also improve the Company's understanding of the spatial relationship between the broad zone of disseminated pyrite and mineralization. This will improve the efficiency of future drill targeting in the area. Bekanntmachung • May 26
Great Boulder Resources Provides Update on Recent Exploration Activity at the Mulga Bill Prospect in the Side Well Gold Project Great Boulder Resources provided an update on recent exploration activity at the Mulga Bill prospect in the Side Well Gold Project ("Side Well") in Western Australia. Additional assays from the recent seven-hole diamond drilling campaign combined with retrospective multi-element assays from earlier RC holes have highlighted the continuity of a broad zone of elevated copper, gold and silver. This tabular, sulphide-rich zone had previously been recognised in Great Boulder's drilling, but a lack of continuous base metal assays hampered interpretation. The sulphide zone contains disseminated chalcopyrite and pyrite, making it a visible feature in the 3D-IP and gravity data. It is commonly located on the eastern margin of the IP anomaly, with the high-grade gold-only intersections to the west. Better copper intersections from the new assays include: 14.5m at 0.59% Cu, 1.17g/t Au and 10.74g/t Ag from 189.5m including 0.7m at 2.25% Cu, 1.48g/t Au and 27.10g/t Ag in 22MBDD001; 17m at 1.21% Cu, 0.35g/t Au and 8.92g/t Ag from 83m in 21MBRC046; 24m at 0.49% Cu, 0.25g/t Au and 3.65g/t Ag from 94m in 21MBRCD093; · 4m at 1.30% Cu, 0.18g/t Au and 68.68g/t Ag from 100m including 1m at 3.44% Cu, 0.15g/t Au and 171.38g/t Ag in 21MBRC051; 10m at 0.40% Cu, 0.04g/t Au and 5.37g/t Ag from 96m in 21MBRC047. The sulphide intersection in 22MBDD001 sits within a 74.6m-wide zone averaging 5.76ppm Bismuth, which suggests it sits within the centre of the alteration system. Following completion of recent RC drilling at Mulga Bill, Loaded Dog and Ironbark an AC drilling program commenced on May 20th. This will complete infill drilling in the southern half of the Mulga Bill corridor where previous coverage is still sparse, with AC lines up to 500m apart. The AC rig is scheduled to move to Whiteheads later in the month to test several geochemical targets as well as some follow-up drilling from previous AC programs. An RC rig is scheduled to mobilise to Side Well in late June with drilling planned to continue for the remainder of the year. Bekanntmachung • May 12
Great Boulder Resources Announces Results from A Recently-Completed Offset Pole-Dipole Induced Polarisation Survey At Mulga Bill, Within the Side Well Gold Project Great Boulder Resources announced results from a recently-completed offset pole-dipole Induced Polarisation (3D-IP) survey at Mulga Bill, within the Side Well Gold Project ("Side Well") in Western Australia. The survey has identified large chargeable zones that are interpreted to be disseminated sulphide bodies beneath the central 3km strike of Mulga Bill. These zones correlate very closely with the gravity anomaly identified by GBR's survey last year. Importantly, the previously-recognised correlation between gold and sulphur in GBR's assay data suggests sulphide zones are an important target for gold mineralisation. The IP survey was completed in mid-April by Moombarriga Geoscience, with data processed by Terra Resources. Terra produced a series of isosurfaces of the modelled chargeable zones, with chargeability measured in units of millivolts per volt (mv/v). Chargeability of 10 to 12mv/v is thought to correlate to 1 to 2% disseminated sulphide. The survey results indicate the presence of cross-cutting structures that intersect Mulga Bill, explaining breaks in both the strike and depth of the sulphide zones. In the area where a gravity-EM "bullseye" target was tested by three RC holes late last year the chargeable response sits deeper than GBR's RC holes, meaning this area requires deeper drilling to properly test the sulphide target. Interpretation of structures using the combined IP and gravity data is ongoing. Board Change • Apr 27

Great Boulder Resources Limited Announces Visible Gold in Mulga Bill Diamond Core At the Side Well Gold Project in Western Australia Great Boulder Resources Limited announced that visible gold has been observed in diamond core from the Mulga Bill prospect at the Side Well Gold Project in Western Australia. Disseminated occurrences of visible gold were noted at a depth of approximately 130m down-hole in diamond hole 22MBDD002 within a 3.1m-wide quartz vein. This hole is now being sampled and submitted for assay. The hole was collared 125m west of RC hole 21MBRC034 which intersected 6m @ 24.33g/t Au from 132m1. The quartz vein in 22MBDD002 is likely to be the same as that in 21MBRC034. The diamond drilling program at Mulga Bill has been temporarily stopped due to bad weather, with seven holes drilled for 1,675m of core. The diamond rig has moved to another job in the area and is expected to return to Side Well to complete the last hole in this program in a few weeks. The 3D Induced Polarisation (3D IP) survey at Mulga Bill has experienced minor delays due to thunderstorm activity and associated lightning interfering with electrical readings. It is now expected to be completed this week. Plans and sections of the diamond holes will be announced once assaying is complete. It should be noted that although 22MBDD002 and 21MBRC034 were collared 125m apart the two holes are drilled towards each other at a dip of -60°, i.e. 22MBDD002 is drilled towards the east while 21MBRC034 is drilled towards the west.

Great Boulder Resources Limited Announces First Assay Results from the 65-Hole Phase 5 Air-Core Program Great Boulder Resources announced the first assay results from the 65-hole Phase 5 air-core (AC) program drilled late last year at Mulga Bill, within the Side Well Gold Project ("Side Well") near Meekatharra in Western Australia. Highlights from the drilling include: 3m @ 8.56g/t Au from 147m in 21MBAC119, including 1m @ 23.78g/t Au from 149m to EOH. This intersection, 1,000m further south than any previous drilling, extends the overall strike of Mulga Bill to 6km. The hole was drilled to 150m at which point the rig ran out of rods, which means high-grade mineralisation remains open at depth. The Mulga Bill system also remains open along strike to the south.

Great Boulder Resources Announces AC Drilling Underway At Whiteheads Project Great Boulder Resources announced AC drilling is underway at the Whiteheads project north of Kalgoorlie in Western Australia. HIGHLIGHTS: A 5,000m air-core (AC) drilling program has commenced at the Whiteheads Project. Five regional targets will be tested, including prospects on the Arsenal Trend. Assays received from the regional AC program completed in Sep-Oct 2021 returned several encouraging anomalous intersections similar to the early-stage drilling at Blue Poles, where thick zones of gold mineralisation were discovered beneath anomalous bottom-of-hole assays in the initial AC coverage. RC drilling results from Side Well are due imminently and diamond drilling is scheduled to recommence next month. Approximately 5,000m of drilling is planned to continue testing five regional targets, including Blue Poles South, Tektite and Highbury on the Arsenal Trend, as well as further drilling at Jubilee North and the first drill program at the Eclipse prospect. Drilling is expected to take approximately three weeks. Once this program is completed a diamond rig is scheduled to commence drilling at the Mulga Bill prospect at Side Well in mid-February. 2021 AC Results: 122 AC holes were drilled at Whiteheads for 5,166m in September and October 2021 testing a range of regional targets including some that had not previously been drilled. These included: 8 holes (439m) at Gunners on the Arsenal Trend, 23 holes (1,127m) at Tektite, south of Blue Poles on the Arsenal Trend, 8 holes (518m) at Highbury, on the Arsenal Trend southwest of Tektite, 6 holes (226m) on a single fence of drilling at Reception Hill, 57 holes (1,919m) along strike to the northwest and southeast of Seven Leaders, 20 holes (937m) at Jubilee North. All assays have now been received. The program generated a number of anomalous intersections, including 1m @ 2.55g/t Au from 41m in 21WHAC110 at Tektite, 4m @ 0.61g/t Au from 80m in 21WHAC128 at Jubilee North and 12m @ 0.23g/t Au from 67m in WHAC174 at Seven Leaders. Importantly, the Tektite and Highbury results continue to add to the potential of the Arsenal Trend south of Blue Poles. Air-core results of this type are encouraging in comparison to early-stage drilling at Blue Poles, where thick zones of gold mineralisation were discovered beneath anomalous bottom-of-hole assays in the initial AC coverage.

Great Boulder Resources Provides Update on the Collaborative Scientific Research Project at the Side Well Gold Project in Western Australia Great Boulder Resources provided an update on the collaborative scientific research project at the Side Well Gold Project in Western Australia. As announced to the market on 6 April 2021 1 a collaborative research project with Australia's national science agency, CSIRO, is underway at Side Well aiming to define techniques for gold exploration beneath transported cover. This 12-month project funded by Great Boulder and the Innovation Connections service of the Australian Government's Entrepreneurs' Programme, is ledby Dr. Walid Salama, Senior Research Scientist at the CSIRO Australian Resources Research Centre in Perth. Dr. Salama's work has led to important breakthroughs in understanding the style of mineralisation at Mulga Bill by mapping the hydrothermal halo around mineralisation in the upper weathering profile using hyperspectral analyses. Dr. Salama has been able to identify the target zone even when the gold has been leached out during weathering. This observation has the potential to greatly reduce exploration costs in deeply weathered areas like Mulga Bill, as target areas can be tested with shallow drilling into the clay zone immediately below transported cover and exploration fairways defined using hyperspectral analysis as a proxy for gold assays in leached horizons. A similar relationship is evidentin fresh rock, where the mineralised zone is characterised by the presence of pure iron-rich chlorite. Pure high Fe chlorite has also been confirmed by calculated mineralogy using geochemical assays. This combination of iron-rich chlorite at depth and a bleached upper saprolite horizon containing remnant iron-rich chlorite provides two diagnostic alteration markers for mineralisation. GBR will now separately assess if the abundance of pure chlorite can be used as a proxy for gold assays by using the same mathematical distribution function which the gold assays describe. Great Boulder intends to build on this discovery, with further work planned in 2022 to look at field- portable hyperspectral analysis of drill samples. If the spatial correlation between hydrothermal indicator minerals and gold mineralisation is strong and reliable enough, hyperspectral scanning has the potential to identify mineralisation at the rig, without the current lengthy wait for gold assays. This will allow GBR's field team to make fast drilling decisions, maximising rig efficiency and reducing unnecessary drilling. A second outcome of Dr. Salama's work is the recognition that gold within the high-grade, pyrite-rich quartz veins sits on the margins of, or cracks within, pyrite. Showing two microscope photographs of sulphide grains from high-grade sample SW04651 from hole 21MBRC002. This observation is significant as it suggests the gold should be easily recoverable by conventional gravity and cyanide leach techniques. Great Boulder intends to commission initial metallurgical test work on samples of RC chips in the New Year. Bekanntmachung • Dec 02
Great Boulder Resources Limited Announces Results from Phase 4 RC Drilling At Side Well Gold Project in Western Australia Great Boulder Resources announced the remaining assay results from Phase 4 RC drilling at the Side Well Gold Project ("Side Well") in Western Australia. Phase 4 was a small campaign of ten RC holes drilled in early to mid-September, with three holes drilled back towards the east to test GBR's new theory of west-dipping high-grade veins. Highlights from the program include: 9m @ 24.19g/t Au from 193m to end of hole, including 1m @ 184.78g/t Au from 193m in 21MBRC054; 2m @ 9.96g/t Au from 87m, 3m @ 24.05g/t Au from 117m and 6m @ 3.08g/t Au from 166m in 21MBRC051; 4m @ 10.11g/t Au from 180m and 8m @ 2.63g/t Au from 189m in 21MBRC046. Hole 21MBRC050 was assayed individually and submitted as a priority, with the intersection of 6m @ 39.15g/t Au from 101m (including 3m @ 74.51g/t Au from 91m) previously announced on 25 October 2021. The result in hole 21MBRC054 (9m @ 24.19g/t Au) is particularly significant as it appears to be shear-related mineralization rather than the flat-dipping, pyrite rich quartz vein-hosted mineralization seen in previous high-grade holes further north. As such the orientation of this zone is uncertain, with diamond drilling planned to gain structural and stratigraphic data in this area as soon as a rig is available. Bekanntmachung • Sep 29
Great Boulder Resources Limited Announces Exploration Results from RC and AC Drilling Within the Side Well Gold Project in Western Australia Great Boulder Resources Limited announced further exploration results from RC and AC drilling within the Side Well Gold Project in Western Australia. Reported RC holes are part of the third phase of RC drilling at Mulga Bill and was completed between late June and early July and AC drilling in mid-July. AC drilling has discovered a new gold prospect approximately 1.5km east of Mulga Bill, with gold intersected on three 100m-spaced drill lines including 8m at 2.39g/t Au from 40m in 21SWAC101. This discovery is hosted within ultramafic lithology and the mineralisation remains open in all directions. Regional AC drilling south of Mulga Bill has extended the prospect by another 1.4km, which means the overall strike length of Mulga Bill is now more than 5km and is not yet closed off along strike. Further south historic drilling has only reached average depths of 30-40m and is therefore deemed ineffective to define further Mulga Bill mineralisation due to near surface depletion in the upper oxide zone. Final results from the Phase 3 RC drilling results highlight the continuity of significant gold mineralisation on the eastern trend at Mulga Bill over 400m in strike. This mineralisation trend has received shallow drilling to date within the supergene environment and is open in all directions. Bekanntmachung • Aug 13
Great Boulder Resources Limited Provides Update on Reverse Circulation Drilling at Blue Poles Discovery within Whiteheads Gold Project in Western Australia Great Boulder Resources Limited provided an update on reverse circulation (RC) drilling at the Blue Poles discovery within the Whiteheads Gold Project in Western Australia. 18 RC holes were completed in the third round of drilling at Blue Poles for a total of 2,545m. Significant intersections include: 5m @ 3.52g/t Au from 181m in 21BPRC026, including 3m @ 5.51g/t Au from 181m; 47m @ 1.18g/t Au from 40m in 21BPRC024, including 19m @ 2.09g/t Au from 59m; and 11m @ 1.64g/t Au from 64m in 21BPRC022. The main zone of supergene gold mineralisation at Blue Poles has now been extended to a strike of approximately 700m, with new holes improving continuity at the northern end. At the southern end an intersection of 3m @ 5.51g/t Au from 181m in 21BPRC026 indicates the potential for higher grade primary mineralisation at depth, implying a possible southern plunge component to the deposit. This intersection remains open to the south and at depth. Deeper holes under the central area of Blue Poles show the broad, thick mineralised zone being attenuated at depth into thinner, west-dipping lodes more typical of a structurally-controlled deposit. Four holes drilled into the Tektite prospect 1,700m south on the Blue Poles trend also intersected mineralisation with a best result of 4m @ 1.99g/t from 56m in 21BPRC041. Drilling will resume at Whiteheads in September, with another air-core program testing regional targets along the Arsenal Trend as well as elsewhere within the project. An RC program will also commence shortly at the Side Well Project near Meekatharra, continuing work on the high-grade Mulga Bill prospect. Bekanntmachung • Jul 20

Great Boulder Resources Announces Assay Results from Reverse Circulation Holes Drilled At the Mulga Bill Prospect Within the Side Well Gold Project in Western Australia Great Boulder Resources Limited announced further assay results from Reverse Circulation (RC) holes drilled at the Mulga Bill prospect within the Side Well Gold Project ("Side Well") in Western Australia. These are the final assays from the drilling
campaign in April. RC DRILLING PROGRAM RESULTS: The remaining results support Great Boulder's interpretation of two sub-parallel lode positions striking north-south through the central area of Mulga Bill. Significant intersections include: 4m @ 7.33g/t Au from 111m in 21MBRC017, including 1m @ 20.68g/t Au from 111m, and 8m. @ 13.36g/t Au from 151m, including 4m @ 26.42g/t Au from 151m. 8m @ 3.31g/t Au from 124m in 21MBRC023. 1m @ 10.99g/t Au from 82m in 21MBRC028. 74m @ 0.76g/t Au from 88m to EOH in 21MBRC019, including 3m @ 2.96g/t Au from 122m and 4m @ 2.40g/t Au from 156m to EOH.
Only three out of 20 holes targeting the western lode position were unsuccessful at encountering significant mineralisation. One of these was abandoned at 21m after it intersected a Proterozoic dyke. This very high success rate for the first RC program targeting this structure is very encouraging for further drilling and inferred continuity. The western zone has been drilled over a 1km strike extent south from a cross-cutting Proterozoic dyke, with a best result of 6m @ 31.25g/t Au from 130m in hole 21MBRC002. The zone appears to be open to the south and also has potential to continue to the north on the other side of the dyke. Five holes targeting the eastern zone were all successful in intersecting significant mineralisation. This eastern zone has now been drilled over an extent of approximately 500m, with a best result of 8m @ 7.51g/t Au from 68m in 21MBRC016. The eastern zone remains open to the north and south. Both lodes remain open down dip and are completely untested at depth.
An intersection of 8m @ 3.31g/t Au from 124m in hole 21MBRC026 is potentially a new mineralised zone. The hole is located north of the dyke, in an area only tested previously by historic AC drilling. An intersection of 16m @ 2.35g/t Au from 100m in 21MBRC017 also contained copper sulphides (chalcopyrite and bornite) with an average pXRF reading of 1.3% Cu. Investors are reminded that pXRF values do not have the same accuracy as laboratory assays, however these readings are further evidence of a relationship between gold and copper in the fresh rock at Mulga Bill.

Great Boulder Resources Limited Announces RC Drilling Recommences At Blue Poles Great Boulder Resources provided an update on exploration at its Whiteheads Gold Project ("Whiteheads") in Western Australia. RC drilling has recommenced at the Blue Poles deposit, with a 2,500m program designed to test extensions to mineralisation north and south as well as adding definition through the central section of Blue Poles. 18 RC holes will cover a total strike extent of approximately 900m, and the program is expected to take 12 to 14 days to complete. Great Boulder has drilled 35 RC holes in the two previous RC campaigns at Blue Poles, defining a broad, steeply dipping and consistent zone of mineralisation over a 450m strike. This zone remains open at depth, and there is potential for other mineralised structures along strike. Upon completion of this program the rig and field team will mobilise to the Side Well Gold Project to start the next round of RC drilling at Mulga Bill. Drilling will follow up high grade intersections in the previous round of drilling, which included 6m @ 31.2g/t Au from 130m in 21MBRC002. Bekanntmachung • Jun 05
Great Boulder Resources Assumes 100% Ownership of the Yamarna Project, East of Laverton in Western Australia Great Boulder Resources announced that it has now assumed 100% ownership of the Yamarna Project, east of Laverton in Western Australia. The Yamarna Project was previously a contributing 75:25 joint venture (JV) between Great Boulder and Eastern Goldfields Mining Company Pty Ltd. EGMC is a private exploration company owned by Goldfields-based businessman Murray Black, who is also a founder and former Director of Great Boulder. Under the terms of the Yamarna JV EGMC's interest was diluting due to ongoing expenditure at Yamarna by Great Boulder, and the Company has now elected to convert EGMC's remaining interest to a 2% Net Smelter Royalty (NSR). This simplifies ownership of the Project while Great Boulder considers a number of strategic options to unlock immediate value for Great Boulder shareholders while maintaining maximum exposure to future upside. Great Boulder's core focus has been on the Mt Venn base metals sulphide deposit discovered in October 2017. Following this the Company completed 13,700m drilling that demonstrated multiple, broad lenses of shallow Cu-Ni-Co sulphide mineralisation. Drill targeting based upon EM surveys has been extremely successful, with sulphides identified in every EM target drilled to date. Mineralisation at Mt Venn occurs within multiple broad lenses, with significant results including: 48m at 0.8% Cu, 0.2% Ni, 0.07% Co from 103m in 17MVRC015. 18m at 0.8% Cu, 0.1% Ni, 0.02% Co from 187m in 17MVRC0013. 18m at 0.7% Cu, 0.2% Ni, 0.05% Co from 92m in 17MVRC0224. 27m at 0.6% Cu, 0.2% Ni, 0.05% Co from 43m in 18MVRC0015. Extensions to the north and south show mineralisation is continuous, consistent and remains open along strike. The Company has only tested the Mt Venn lodes to a maximum depth of 260m below surface. The Eastern Mafic Complex is a less advanced exploration project. With only 36 RC and Diamond holes drilled since its discovery in 2018, Eastern Mafic hosts a number of Ni-Cu-Co sulphide prospects which require further drilling to unlock their full potential. Metallurgical test-work has shown that the Mt Venn sulphides are amenable to simple grinding and flotation to recover a copper concentrate, followed by leaching of the tails to recover nickel and cobalt into solution. With metal extractions of greater than 90% achieved in testing this makes Mt Venn an attractive proposition for the battery metals market. Bekanntmachung • Jun 04

Great Boulder Resources Limited Announces More high-grade intersections at Mulga Bill Great Boulder Resources announced assays from an additional thirteen Reverse Circulation (RC) holes drilled at the Mulga Bill prospect within the Side Well Gold Project (Side Well) in Western Australia. These results follow initial
results announced on 5 May 2021 which included the exceptional intersection of 6m @ 31.2g/t Au from 130m in hole 21MBRC002, including 1m @ 136g/t Au from 132m. Drilling in the central Mulga Bill area has highlighted two sub-parallel, high-grade lodes with significant strike potential. Significant gold intersections on the western lode line up with previous drilling over an approximate strike length of 600m, while the eastern lode has apparent continuity over 500m. Highlights include: 16m @ 5.52g/t Au from 84m and 8m @ 4.06g/t Au from 132m in 21MBRC010 within a broad mineralised zone of 68m @ 2.05g/t Au from 80m, 8m @ 7.51g/t Au from 68m in 21MBRC016, 8m @ 4.67g/t Au from 124m in 21MBRC013, including 4m @ 8.52g/t Au from 124m. Assays from the remaining 13 RC holes will help confirm continuity on these lodes, which will be further tested by future RC programs. Gold is associated with strong sulphide mineralisation and quartz veining. The two lode structures appear to be developed on the contacts between quartz-feldspar porphyritic intrusions and the surrounding volcanic/volcaniclastic package, and these positions will be targeted in follow-up drilling programs.

Two of the first three holes assayed intersected significant gold mineralisation, including 6m @ 31.2g/t Au from 130m in hole 21MBRC0022. These results are expected to be available in the next three to four weeks. A soils program consisting of 948 samples over the Jones Well area is also due to be assayed by the end of May. This area has not previously been explored. The recent AC program at Whiteheads included 100 holes for 4,267m testing a number of targets along the Arsenal Trend including the Gunners prospect north of Blue Poles. Two other soil anomalies at Jubilee North and Hillsborough were also drilled for the first time. Initial assays from this program are expected by the end of June. Bekanntmachung • May 08
Estrella Resources Limited Announces Gold Update at Carr Boyd Estrella Resources Limited announced that it takes note of Great Boulder Resources Limited large scale gold discovery at Blue Poles. GBR's Blue Poles discovery is located within the Whiteheads Project (GBR earning 75% from Zabina Minerals) and is situated 4 kilometers south of Estrella's Carr Boyd tenements on what has been named the Arsenal Trend. Also of significance to Estrella is GBR's Whiteheads Trend which hosts the Seven Leaders Prospect. The
Whiteheads Trend has been mapped through Estrella's ground and the Seven Leaders Prospect lies on the tenement boundary. At both Blue Poles and Seven Leaders, GBR has reported significant widths and grades of gold mineralisation. The Arsenal Trend and Whiteheads Trends traverse the shared southern boundary between GBR's earn-in with Zabina Minerals and Estrella's E31/1162. Arsenal Trend - Estrella notes the existence of similar geology to Blue Poles within the Company's eastern tenure on the edge of the Carr Boyd Igneous Complex. The company believes the Arsenal Trend continues into this area. Work by Estrella dates the Carr Boyd Complex as older than the regional gold mineralizing events and as such the sheared edge of the complex is highly prospective for gold where the Arsenal Trend is projected to continue through. The company has not completed any work on this edge of the complex recently. Whiteheads Trend - Recent mapping of the Carr Boyd intrusion revealed a structural corridor between the Seven Leaders mineralisation and historical gold workings at Estrella's Porphyry Hill gold prospect, the Marsh Dam workings and the Granite gold prospect, all within the Carr Boyd Igneous Complex. The total distance between Seven Leaders and Granite Au workings is over 15 kilometers. Whiteheads Trend - Recent mapping of the Carr Boyd intrusion revealed a structural corridor between the Seven Leaders mineralisation and historical gold workings at Estrella's Porphyry Hill gold prospect, the Marsh Dam workings and the Granite gold prospect, all within the Carr Boyd Igneous Complex. The total distance between Seven Leaders and Granite Au workings is over 15 kilometers. Several historic shafts were mined at Porphyry Hill where gold mineralisation hosted in quartz veining has occurred on the contact between felsic pyroclastics and mafic sediments. Grab samples of the shaft spoils by Defiance Mining (1988) ran between 1.5g/t and 39.3g/t Au. Salt Lake Mining (2013) obtained grades from 0.25g/t to 70g/t, also from the shafts. A RAB result by Defiance Mining graded 4m @ 4.10g/t from 20m in PHR22. At the Granite Prospect, only 9 RAB holes were drilled below and along side old workings by Defiance Mining. A result of 4m @ 1.23g/t from surface in GSR3 was obtained however no further work was done. Marsh Dam gold mineralisation is hosted along the margins of laminated faults within peridotite. The veins have been worked for gold. Subsequent exploration was not successful due to the inability of RAB drilling to penetrate the duricrust effectively to test for extensions of mineralisation.

Great Boulder Resources Limited Announces Drilling to Recommence at Blue Poles Great Boulder Resources is pleased to provide an update on exploration activities at its Whiteheads Gold /Nickel Project (Whiteheads) located in Kalgoorlie and Side Well Gold Project (Side Well) located in Meekatharra. An RC rig will mobilise to Whiteheads next week to commence a 2,000m program of infill and extensional holes at the Blue Poles gold discovery. Drilling at Blue Poles in November 2020 defined broad zones of primary gold mineralisation over a 700m strike, open to the south and at depth. The current drill program will aim to infill this area and test extensions to the south. On completion of the Blue Poles drilling the same rig and field team will move to Side Well to complete a 4,000m program at Mulga Bill. This drilling will test mineralised trends beneath the supergene zone previously defined by two campaigns of air-core drilling. Bekanntmachung • Mar 16

Great Boulder Resources Announces Initial Results from the Completed Whiteheads High-Resolution Gravity Survey Great Boulder Resources announced initial results from the completed Whiteheads high-resolution gravity survey. The survey has confirmed a large low gravity feature striking south from outcropping granite in the north-eastern corner of the project, coincident with the position of the Arsenal Trend gold- in-soil anomaly. The feature is interpreted to represent a finger of felsic intrusive plunging south beneath the Arsenal Trend. This is a classic "heat engine" setting for mineralising fluids, with the granite and associated felsic intrusions providing the heat necessary to force hot, mineralised fluids and gasses through the region. This interpretation explains the broad, coherent gold anomalism found at surface along the Arsenal Trend. Wherever mineralising fluid encounter a suitable setting to reduce fluid temperature such as a sudden pressure drop, or an increase in pH, the gold may precipitate. These features explain the location of Blue Poles. Other evidence supporting this theory include an apparent temperature gradient between Blue Poles at the northern end of the Arsenal Trend and Four Dudes to the south. The presence of widespread actinolite at Blue Poles indicates high-temperature thermal metamorphism and alteration, while anomalous Antimony in auger drilling at Four Dudes indicates a lower-temperature setting. The two prospects are 13km apart, providing an indication of the overall scale of the system. The Company's exploration going forward will use this information to continue exploring the Arsenal Trend for other Blue Poles-style gold occurrences. In the meantime, on-going interpretation of the gravity data is looking for evidence of Carr Boyd-style intrusive-related nickel targets. Further information will be provided to the market as it becomes available. An RC drilling program is scheduled for Blue Poles in the second half of March to infill and extend the zone of primary gold mineralisation. Air-core (AC) drilling is being planned to test the look-alike auger anomaly north of Blue Poles. This is expected to be completed during April. Any high-priority nickel targets will need to be tested with an aerial EM (electromagnetic) survey prior to planning drill testing. Bekanntmachung • Jan 19
Great Boulder Resources Limited Announces the Results from the Maiden Reverse Circulation Drilling Program Great Boulder Resources Limited announced the results from the maiden reverse circulation (RC) drilling program confirming the discovery of new gold mineralization at the Company's Blue Poles Prospect, situated within the Whiteheads project north of Kalgoorlie. Fifteen RC holes were drilled for a total of 1,448m in late November to test primary gold mineralization beneath recent air-core (AC) drilling intersections. Two holes were added to the program to target a lead-zinc prospect west of Blue Poles. The program identified primary mineralization over a 700m strike length, including broad zones of up to 52m @ 1.02g/t Au from 28m to the end of hole in 20BPRC006. Lower grade intersections over significant widths include 28m @ 0.61g/t Au from 32m in 20BPRC010, 29m @ 0.66g/t Au from 68m in 20BPRC009 and 42m @ 0.45g/t Au from 28m in 20BPRC012. These intersections are initial assays on 4m composite samples. The composite samples will now be re-sampled on an individual metre basis, which may result in the identification of discrete zones of higher grade mineralization within each interval. The program comprised 17 RC holes for a total of 1,706m. All holes were drilled to the west at a dip of -60° in order to cross-cut stratigraphy. Petrographic analysis of AC chips identified alteration and foliation consistent with a large, structurally controlled mineralized system. The RC results support this view, however there is insufficient data to confirm the dip of the mineralized structure at this stage. In the next round of RC drilling a number of holes will be drilled towards the east to confirm the dip of Blue Poles mineralization. At Whiteheads a ground gravity survey is expected to commence in late January. Gravity data will be collected at approximately 1,400 stations on a 400 x 200m grid on the eastern side of Whiteheads, complementing a survey completed previously by Pioneer Resources Ltd. on the western side of the project. The survey will assist Great Boulder to identify Carr Boyd-style ultramafic targets at depth. The gravity data will also be used to refine the Company's interpretation of possible mineralizing fluid pathways or natural plumbing systems driven by buried felsic intrusions north of Blue Poles.

Great Boulder Resources Announces Updates on Side Well Gold Project Great Boulder Resources announced the results of recent air-core (AC) and auger programs at the Side Well gold project near Meekatharra in Western Australia.
The 6,166m AC program has confirmed the strike of mineralisation within the Mulga Bill corridor, with multiple parallel north-south mineralised trends now apparent. Gold has now been identified over more than 3.7km of strike, and mineralisation remains open to the north and south. A follow-up drilling program will commence as soon as a rig is available. The AC program was designed to infill the 400m line spacing of previous drilling, bringing coverage to an average line spacing of 200m, with an aim to add further confidence to the geological interpretation. Auger anomaly at eastern Side Well: While AC drilling was underway the Company also completed an auger program over approximately 6km of prospective strike on the eastern side of Side Well. The auger sampling consisted of samples every 50m on lines 400m apart, covering an area of outcropping banded iron formation (BIF) and associated mafic volcanics. The BIF units are a continuation of the same stratigraphy that wraps around the Pollele Syncline from Paddy's Flat, continuing southeast from Side Well into the Gabanintha area.
The area covered by the auger program includes one historic shaft identified by GBR's geologists, as well as a small nugget patch recently worked by local prospectors. Multi-element analysis of the samples has identified a high-tenor gold pathfinder anomaly over an 800m area, with arsenic above 90ppm and antimony above 1ppm. The data also shows a broad silver anomaly at the southern end which are coincident with the highest gold values, with
silver above 0.1ppm (100ppb) for over 1,200m of strike, and a peak gold value of 40ppb. The relatively subdued gold response may reflect the lack of a well-developed pedogenic carbonate horizon at Side Well. Carbonate in soil acts as a collector of any gold moving in groundwater through the soil profile, making it an ideal medium for auger sampling. The strong response from pathfinder elements, particularly arsenic and antimony, is a positive indicator of gold potential in early-stage exploration geochemistry. Bekanntmachung • Nov 19

Great Boulder Resources Announces Results from the Second Phase of Air-Core (AC) Drilling Great Boulder Resources announced results from the second phase of air-core (AC) drilling at the Company's Blue Poles discovery, within the Whiteheads project north of Kalgoorlie. This phase of drilling was designed to define the limits of mineralization at Blue Poles prior to RC drilling, which is scheduled to be completed this month. Blue Poles has now been closed off to the north but remains open to the south. The total strike length of the prospect is now in excess of 1km. A single fence of AC holes drilled across a smaller geochemical target to the northwest also intersected anomalous mineralization which will require additional testing in future programs. Initial RC drilling is expected to begin at Blue Poles in the second half of November, slightly behind schedule due to a short delay in the contractor's availability. VMS-style Pb-Zn discovery: In other results, a fence of holes drilled to the west to provide additional geological information intersected lead-zinc sulphide minerals at the bottom of a hole 500m west of Blue Poles. Assays include: 1m at 13g/t Ag, 1.04% Pb and 1.01% Zn from 92m, and 2m at 7.35g/t Ag, 0.63% Pb and 0.80% Zn from 97m to EOH in 20WHAC105. This is a completely new discovery in an area with no surface geochemical signature. The Company will plan further work in order to assess the nature and scale of base metal mineralization. The second round of drilling at Blue Poles consisted of 51 holes for 2,476m. Holes were mainly drilled along strike to the north and south of previous coverage. Holes were also drilled to test discrete gold-in-soil anomalies nearby, plus one fence of drilling which extended approximately 600m west in order to gain additional information about the local stratigraphy. All holes were drilled at a dip of -60° towards 270° (west). Samples were mainly composited in 4m intervals, with any sections of notable alteration or veining preferentially sampled in single metres. As with previous programs, all 4m composites returning a gold grade above 0.1g/t Au will be re-split and assayed as individual 1m samples. Bekanntmachung • Nov 13
GBR Sponsorship Unlocks Access to New Exploration Technology Great Boulder Resources announced that it has entered into a sponsorship agreement with Portable ppb Pty Ltd. (PPPB) which will allow the Company to access PPPB's detectORETM technology in its field exploration programs. detectORETM, invented by Dr. Mel Lintern at CSIRO, is a patented technology which enables handheld pXRF guns to detect gold values to less than 10ppb (parts per billion) in near real time field samples. This represents a massive potential gain in terms of time and expense, by speeding up the assay time from many weeks in a commercial laboratory to an overnight process in the field. To put this into context, current pXRF technology cannot detect gold in concentrations of less than 1,000ppb (1g/t Au). Gold-in-soil anomalies in Western Australia tend to be in the range of 10ppb to 50ppb. Using detectORETM will enable GBR to quickly vector in on anomalous prospects, defining areas of interest with multiple rounds of soil geochemistry within a matter of days instead of months. There is also potential for the technology to be used on composited and individual drill samples to reduce the volume and time involved with sending samples to Perth for gold and costly multi-element analysis. Importantly, this will enable its geologists to receive quick feedback while drill rigs are on site and therefore make timely informed decisions on where to drill next. detectORETM is in the advanced research and development stage and not yet available for general commercial use. By partnering with PPPB as a sponsor GBR will be able to participate in field trials and ongoing development of the technology, gaining pre-competitive access and resultant savings.

Great Boulder Resources Provides Phase 2 AC Drilling Commences at Whiteheads Great Boulder Resources Limited provided a further update on exploration programs at the Side Well and Whiteheads gold projects. Side Well: Phase 1 drilling programs complete; The first round of air-core drilling at Mulga Bill has been completed, with 66 holes drilled for a total of 6,159m. This program concludes the initial drill testing at Mulga Bill. Further drilling is planned in November, pending receipt of assays from the recently completed RC and air-core programs. A program of 641 auger holes has also been completed covering prospective stratigraphy on the eastern side of Side Well east of Mulga Bill. This area, previously unexplored, includes outcropping banded iron formation on the eastern limb of the Pollele Syncline which trends south to the Gabanintha mining centre. The Company currently has more than 4,000 samples at the assay laboratory in Perth awaiting assay. Whiteheads: Phase 2 Blue Poles AC drilling underway: The second round of air-core drilling has commenced on schedule at the Blue Poles prospect. This program will test extensions to mineralisation to the north, south and southwest to determine the full extent of the mineralised area. Fences of drilling have also been designed to test two smaller geochemical anomalies to the north and south of Blue Poles anomaly on the Arsenal Trend. The next round of RC drilling at the Whiteheads and Side Well gold projects is scheduled for early November. This drilling will test mineralisation at depth beneath the Blue Poles air-core intersections. A second round of RC is also planned to infill and extend the Mulga Bill area. Further work will be planned based on the results of both these programs. Bekanntmachung • Sep 18

Great Boulder Resources Limited to Provide an Update on Exploration Programs at the Side Well and Whiteheads Gold Projects Great Boulder Resources Limited to provide an update on exploration programs at the Side Well and Whiteheads gold projects. Phase 1 RC drilling at the Mulga Bill prospect has been successfully completed, and all remaining samples are now on their way to be assayed in Perth. The Phase 1 program consisted of 12 holes for 2,257m, with holes designed to extend known zones of mineralization at Mulga Bill. Full program details and hole coordinates will be provided in a subsequent update once the initial assay results are available. A 6,000m air-core program is now commencing, also at Mulga Bill. This drilling will infill the 400m gaps between previous RC drilling, providing detail on the position of the Mulga Bill mineralized corridor with which to plan the next round of RC drill holes. An extra fence of air-core holes has also been added to the south of Mulga Bill to test possible continuity in that direction, based upon GBR's analysis of a heli-TEM survey flown by Doray in 2013. Lastly, a 600-hole auger program is also scheduled to commence over the banded iron formation (BIF) stratigraphy on the eastern side of the Side Well project, to the east of Mulga Bill. This area includes residual soils and sub-crop with no alluvial cover, making it ideal for auger sampling. BIF is a common host for gold mineralization in the Meekatharra area, and GBR personnel have observed recent metal detecting patches within the area covered by the auger program. All auger samples will be submitted for multi-element assay later in September. Re-sampling of the anomalous 4m composite samples from the recent air-core drilling has now been completed, confirming the results previously announced to the market. Best results include: 4m at 3.35g/t Au from 50m to EOH in 20WHAC003; 20m at 0.54g/t Au from 32m, including 5m at 1.19g/t Au in 20WHAC008, and 15m at 0.57g/t Au from 33m in 20WHAC034 at Blue Poles; 2m at 1.76g/t Au from 33m in 20WHAC042 at Gindalbie; 3m at 3.14g/t Au from 16m in 20WHAC047 at Whiteheads Dam. As previously announced, the air-core drilling is designed to find anomalous mineralization, so these results at the top of fresh rock are very encouraging. The prospect has been defined over a 600m strike length and mineralization remains open along strike and to the southwest. A second round of air-core drilling will test extensions at Blue Poles prior to the first round of RC drilling.
