Andrada Mining Limited Reports Final Grab Sample Results from Lithium Ridge Project Andrada Mining Limited announced the final grab sample results from the Lithium Ridge Project. The sampling programme has been undertaken in accordance with Stage 1 of an earn-in agreement in partnership with Sociedad Química y Minera de Chile SA through its subsidiary SQM Australia (Pty) Ltd. The results have extended the surface mineralisation of lithium ridge by 50% to a total of nine kilometres. The results also identified high grade lithium, tin and tantalum anomalies within multiple new pegmatites across the licence area. This builds on the initial results which confirmed the presence of mineralisation along the primary Lithium Ridge trendline as disclosed in January 2026. Significant surface lithium grades: multiple grab samples returned grades exceeding 3.5% Li2O with associated tin and tantalum anomalies indicated. Expanded mineralised system: high-grade lithium samples extended the mineralised strike of the main Lithium Ridge trend from six to nine kilometres. Additional targets identified: The results identified multiple mineralised new pegmatites beyond the primary mineralised trend, containing high grades of lithium and associated minerals. Polymetallic upside: Grab samples consistently returned high-grade tin (Sn) and tantalum (Ta) with grades up to 7.38% Sn and 3,192 ppm Ta. In the third quarter of the 2025 calendar year, Andrada commenced a licence-wide geological mapping and grab sampling programme as part of the Stage 1 earn-in agreement with SQM to identify additional mineralised pegmatites within the Lithium Ridge mining licence. The Programme identified approximately 1,500 outcropping pegmatites through satellite and aerial imagery from which a total of 1,230 grab samples were collected. The initial results for 496 samples were reported on 26 January 2026, and the results for the remaining 734 samples are disclosed in this announcement. The samples were selected for analysis based on field identification of visible spodumene or other indicator minerals. Additional samples where no visible lithium minerals were identified, were systematically selected to investigate mineralisation that may not have been apparent during mapping and sampling. These samples will build a geochemical database of the pegmatites across the project area. These new results contained 60 samples that recorded lithium grades above 1% Li2O, including 48 with values above 2% Li2O. These high-grade samples originated from multiple pegmatites across the license area, demonstrating the potential scale of the mineralised system and potential for additional mineral discoveries as the project advances. All the analysed samples were exclusively collected from pegmatites, and no samples of the surrounding host rock were selected for analysis. While visual identification, supported by Raman Spectroscopy, indicated spodumene as the primary lithium mineral, two samples from a single pegmatite returned grades with Li2O values exceeding 8% and also contained elevated phosphorous levels. The samples that returned significant lithium grades during field identification were used to select the pegmatites for diamond drilling, which took place at the same time as the surface sampling. In addition to the significant lithium grades recorded, numerous samples contained significant tin and tantalum mineralisation, with 160 samples reporting grades above 0.1% Sn and 163 samples reporting grades above 75 ppm Ta. Most of these high-grade tin and tantalum samples were obtained from pegmatites which also contained significant lithium grades, further underscoring the polymetallic potential of Lithium Ridge. The grab samples were collected by qualified mapping teams with the location of each sample recorded using handheld GPS devices. The samples were submitted in their entirety to SA Labs Ithuba for pulverisation and homogenisation, with the pulps subsequently dispatched to UIS Analytical Services for geochemical analysis which are independently certified laboratories. A sodium peroxide fusion coupled with ICP-OES analysis were used to determine Li and other major element abundances, while lithium borate fusion and ICP-MS analysis were performed to obtain Sn, Ta and other minor or trace element abundances.

Andrada Mining Limited Reports Third Batch of Lithium Ridge Drill Results Andrada Mining Limited announced the third batch of results for an additional six holes of diamond drilling at Lithium Ridge Project. The additional six holes show the presence of consistent high-grade lithium mineralisation from surface. High-grade lithium mineralisation confirmed across multiple drill holes, including: Drill hole LRD027: 9.05m @ 2.28% Li2O from 50.82m to 59.87m. Including 3.97m @ 3.46% Li2O from 51.82m to 55.79m. Drill hole LRD023: 9.64m @ 1.24% Li2O from 50.36m to 60.00m. Including 5.11m @ 1.89% Li2O from 53.58m to 58.69m. Drill hole LRD024: 13.27m @ 1.42% Li2O from 32.06m to 45.33m. Including 6.79m @ 1.90% Li2O from 32.90m to 39.69m. Drill hole LRD037: 3.97m @ 0.95% Li2O from 48.78m to 52.75m. Including 1.51m @ 1.51% Li2O from 51.24m to 52.75m. Consistent associated tin and tantalum mineralisation confirmed across all holes potentially enhancing project economics through potential polymetallic revenue streams. Drill hole LRD029: 4.97m @ 0.21% Sn and 130ppm Ta. Successfully completed the extended Stage 1 drilling campaign, delivering 143 holes comprising 16,500 metres of oriented core. The results refer to an additional six drill holes and are reported as 'Whole Intersections' in Table 1, representing pegmatite intersections from the top to the bottom contact. Where these intersections contain schistose xenoliths, the reported grades reflect the metal content of the pegmatite only, excluding the schistose intervals. Intersections reported as 'including' represent selected higher-grade zones within the total pegmatite intersection. Spodumene has been visually identified as the primary lithium-bearing mineral by the project geological team. Tin and tantalum grades have also been highlighted as potential by-product revenue streams. The boreholes were drilled at inclined angles to the horizontal and, accordingly, the reported intersections are considered to represent apparent widths rather than true thicknesses. Pegmatite intersections that did not meet at least one of the following metal content cut-off criteria (>0.25% Li2O, >0.1% Sn or >99ppm Ta) have not been reported as they are currently regarded as economically insignificant. Downhole orientation surveys were conducted at regular intervals for each hole as the drilling was advancing and surveyed in totality after drilling was completed. The surveys were conducted using a magnetic deviation probe that collected readings at two metre intervals whereas collar locations were surveyed using a handheld GPS. The Stage 1 drill programme was expanded by 18% to 16,525 metres of orientated diamond core across the license area and was completed in May 2026. Individual drill holes were geologically and structurally logged prior to being cut and sampled as quarter core. The sampling programme followed geological contacts while simultaneously maintaining consistency in data and sample representativity. Sample lengths ranged from 25 cm to 125 cm, where practicable. The samples were submitted to independent and certified laboratories, namely SA Labs Ithuba for pulverisation and homogenisation, and the pulps were subsequently dispatched to UIS Analytical Services for chemical analysis. Lithium and other related major elements were analysed using sodium peroxide fusion with ICP-OES, while tin, tantalum and other trace elements were analysed using lithium borate fusion with ICP-MS. No top cut was applied in calculating the weighted average grades for mineralised intersections within the pegmatites.
