Rockfire Resources plc Provides Drilling Update on Its Molaoi Zinc Deposit in Greece Rockfire Resources plc provided the market with a drilling update from Rockfire's 100%-owned Molaoi zinc deposit in Greece. Diamond drilling to upgrade the Inferred Resource to Indicated Resource status continues with hole HMO-016 successfully completed and drilling of hole HMO-017 currently in progress. Several narrow, but strong zones of mineralisation have been encountered in hole HMO-016 based on portable X-Ray Florescence ("pXRF") readings of drill core. An individual pXRF reading of 54.3% Zn has been recorded at 314.5m downhole depth. This represents the second-highest grade of zinc ever encountered at Molaoi, with the highest being 62.0% in historical hole B027 at a depth of 53m. In the same narrow zone at 314.5m downhole depth, other note-worthy pXRF readings include 39.9% Zn, 35.8% Zn and 27.0% Zn. Also, at 314.5m downhole depth, pXRF values up to 31.8% Pb and 24.2% Pb have been recorded, as well as 470g/t Ag and 382g/t Ag. At a depth of 407m downhole, another narrow zone of mineralisation was intersected. This intersection has returned individual, spot pXRF results including 12.4% Zn, 13.0% Zn, 12.2% Zn and 10.6% Zn. This zone also hosts high grade silver, with average pXRF values from all readings taken in this interval of 44.8g/t Ag. Individual pXRF readings of 18.2% Zn, 13.9% Zn and 10.4% Zn occur at 418m downhole depth. The last intersection occurs at 422m downhole, where pXRF readings include 13.9% Zn, 9.7% Zn and 6.6% Zn. This zone includes individual pXRF readings up to 118g/t Ag and 3.6% Pb. At a downhole depth of 424m, an individual pXRF reading of 0.88% Cu has been recorded. The pXRF machine only provides a guide to the strength of mineralisation and does not detect germanium. The core is routinely analysed for germanium at the laboratory. Core samples from hole HMO-016 have been sent to the laboratory for analysis and analytical results from hole HMO-015 are still awaited. Duyuru • Apr 10
Rockfire Resources Plc Provides Molaoi Drilling Update Rockfire Resources plc provided the market with a drilling update from Rockfire's 100%-owned Molaoi zinc deposit in Greece. Diamond drilling to upgrade the Inferred Resource to Indicated Resource status continues with drilling of hole HMO-015 going well and currently in progress. Results from several holes have recently been received from the laboratory. Strong germanium grades continue to be intersected all the way through the southern zones of the resource area. Hole HMO-012 (south and west extension drill hole) encountered a zone 2m wide at 67.23m depth which assays 4.3% Zn, 20.5g/t Ge and 23.7g/t Ag. This zone includes 0.75m @ 8.9% Zn and 30.1g/t Ge. A 1m wide zone at 76m depth has returned 59.0g/t Ag and 0.2% Cu. A narrow (0.15m) interval at 119.85m depth has intersected 1.7% Cu, which is the second-highest copper value ever recorded at Molaoi. Copper tends to become stronger towards the central "feeder zone" of VMS deposits and can act as a vector towards the source of the deposit-wide mineralisation. Hole HMO-013 (south and west extension drill hole) encountered a 1.2m wide zone grading 32.2ppm Ag, 1.2% Pb, 4.86% Zn and 17.9g/t Ge. This zone occurs at 47.0m depth. Hole HMO-014 encountered slow and difficult drilling conditions. This hole had a target depth of more than 380m but was suspended at 195.80m due to caving of the hole and will be re-drilled later. Despite this, the hole has intersected individual spot pXRF values including 13.86% Zn, 7.5% Pb and 66ppm Ag at a depth of 172m, which is well above the anticipated zone of mineralisation below 350m depth. It is confirmed by analysis that there is no gold in holes HMO-012 or HMO-013 associated with the high barium values. A break in drilling activities will occur for the Orthodox Easter celebrations. As some of the drilling contractors will travel home throughout Europe for Easter, drilling is expected to recommence on the 20th of April 2026. The Rockfire Board has committed to the acquisition of the Company's own drilling rig. This cost will be met from existing cash reserves, and no additional raising will be required to finalise this acquisition. The cleanliness of the pXRF machine is established by measuring a BLANK reference material (a translucent quartz crystal) at the beginning of each day. A Certified Reference Material (CRM) specific to volcanic-hosted massive sulphide Zn-Pb-Cu-Ag-Au ore (ORES 620) was measured for accuracy/precision of the pXRF machine with a reading taken at the beginning of each day. Drill hole location map within the Molaoi Licence. The southern part of the licence continues to intersect narrow, but strong zinc and germanium grades. The copper grades being encountered are becoming more frequent. VMS deposits, even when over-printed by later epithermal mineralisation stem from a central volcanic vent. This central vent is typically characterised by higher copper values and Rockfire will use the copper values being collected from drilling to help vector towards discovering the core of the mineralisation. An expert in drilling through unstable, friable ground has visited site and has made several recommendations which may assist drilling through the broken ground being encountered above the orebody. In the absence of a second drilling rig being provided by contractor in Athens, the Rockfire board has committed to buying Rockfire its own brand-new drilling rig. The cost of this acquisition will be met from existing cash reserves, and no additional raising will be necessary to meet this cost. It is expected that the Company's drilling costs will reduce, allowing for more metres drilled within the existing budget. The drilling campaign continues. As the company pursues the drill-out of the resource, it will continue to update the market with drilling progress including analytical results from the laboratory as they are received and interpreted. The Molaoi deposit in Greece has a JORC Inferred Mineral Resource of 15.0 million tonnes @ 7.26% Zn, 1.75% Pb and 39.50g/t Ag, for 1.5 million tonnes of ZnEq. metal. This resource uses a 4% low-grade cut, and equates to 1.09 million tonnes of zinc, 260,000 tonnes of lead and 19.1 million ounces of silver. Molaoi is also reported under the UNFC Code with classification E2, F2.1, G3 for Zn, Ag, and Pb, and E3.2, F3.1, G4.1 for Ge. New Risk • Apr 10

Rockfire Resources plc Announces Molaoi Drilling Update Rockfire Resources plc provided the market with a drilling update from Rockfire's 100%-owned Molaoi zinc deposit in Greece. Diamond drilling to upgrade the Inferred Resource to Indicated status continues smoothly with the completion of hole HMO-013 at 220.40m. Drilling of hole HMO-014 has commenced. The following quoted readings are from a portable X-ray Florescence machine and do not represent precise geochemical analyses. Geochemical analysis of all anomalous pXRF recordings will be analysed at ALS Laboratories for definitive geochemical content. In all previous drill holes, Rockfire has found good correlation between pXRF readings and actual geochemical analytical results. In hole HMO-013, at 140m depth, 39.9% Zn is registering with pXRF, along with 11.6% Zn at 144.26m depth. At a depth of 50m, an individual pXRF reading registered 22.0% Zn, whilst at 53.8m depth, the pXRF reading is 9.0% Zn. A new development is that copper is starting to become more apparent. Individual pXRF readings of 0.53% Cu, 0.67% Cu, 0.53% Cu,0.53% Cu, and 0.88% Cu are registering at 68m, 83m, 125m and 144m depth respectively. pXRF readings have returned a peak copper value of 1.03% Cu at 201m depth. It is known from metallurgical tests that copper up to 2% reports to a copper/lead/silver concentrate. The highest individual copper grade in historical drilling at Molaoi is a single sample of 2.67% Cu, with the next highest historical assay being 0.58% Cu. Copper results being returned from recent Rockfire drilling are beginning to surpass many of the historical high copper values. At a depth of 48.10m, an individual spot pXRF sample recorded a reading of 252ppm Ag. The same reading returned 6.7% Zn and 10.6% Pb. This reading is amongst the highest silver readings achieved at Molaoi. The silver analysis recorded at Molaoi is 480ppm Ag in historical hole BG008, with the second highest reading being 286ppm Ag in historical hole AN011. Barium has again returned strongly anomalous readings of 19.3% Ba and 17.0% Ba at depths of 52m and 106m respectively. Barium is of interest as this mineral is often associated with low-sulphidation silver/gold epithermal mineralisation. The upper interval at 52m is associated with 39.0ppm Ag from pXRF readings. This interval will be analysed for gold as well. The pXRF equipment does not measure germanium values, but germanium will be analysed at the laboratory. Assay results from hole HMO-011 are awaited and core from hole HMO-012 has been sent to the laboratory. In the absence of a satisfactory timeline for the delivery of a second drilling rig, Rockfire has obtained an initial quote from Athens to acquire its own modern and well-equipped drilling rig. Rockfire has access to highly experienced drillers who could operate the rig and train local drillers on behalf of the Company. The board is considering this alternative, and the market will be updated accordingly. The cleanliness of the pXRF machine was established by measuring a BLANK reference material (a translucent quartz crystal) at the beginning of each day. A Certified Reference Material (CRM) specific to volcanic-hosted massive sulphide Zn-Pb-Cu-Ag-Au ore (ORES 620) was measured for accuracy/precision of the pXRF machine with a reading taken at the beginning of each day".

Rockfire Resources plc Provides Molaoi Drilling Update Rockfire Resources plc provided the market with this drilling update from Rockfire's 100%-owned Molaoi zinc deposit in Greece. Diamond drilling to upgrade the Inferred Resource to Indicated status resumed after the Christmas/New Year break on the 13th of January, as scheduled. The fourth drill hole, (HMO-011) has now completed successfully at a total depth of 250.10m and drilling of the next hole has commenced. Hole HMO-011 is a hole drilled in the very south of the resource and confirms that mineralisation continues and remains open towards the south. Several narrow, mineralised intervals have been intersected in hole HMO-011 in line with expectations from resource modelling. A zone of 1.75m width has returned peak pXRF values of 23.16% Zn, 64ppm Ag, and 2.2% Pb from 36.3m depth. Between 105.00m and 105.65m depth (0.65m), pXRF readings returned values including 7.87% Zn, 1.2% Pb and 41g/t Ag. A noteworthy interval of 0.65m width at 127.60m depth has intersected a vein of barium with average pXRF readings of 65.6% Ba. Barium is of particular interest, as this mineral is often associated with low-sulphidation silver/gold epithermal mineralisation. Importantly, this vein also hosts an average of 71.66g/t Ag from four pXRF readings. This interval will be analysed for gold as well. pXRF readings are considered preliminary and all the intervals identified will be comprehensively analysed at ALS Laboratories in Ireland, including for germanium, which is not measured by the pXRF equipment. Assay results from hole HMO-010 are awaited and core from hole HMO-011 will shortly be sent to the laboratory. A Hydrology Study remains in progress to monitor and measure water quality and quantity prior to mining being undertaken. An Ecological Study is in progress to observe and record fauna and flora surrounding Molaoi prior to any planned mining activity commencing. A second rig is still awaited and drilling contractor, Geotest Consulting Engineers in Athens continues to advise Rockfire that a second rig is soon to be provided. The cleanliness of the pXRF machine was established by measuring a BLANK reference material (a translucent quartz crystal) at the beginning of each day. A Certified Reference Material (CRM) specific to volcanic-hosted massive sulphide Zn-Pb-Cu-Ag-Au ore (ORES 620) was measured for accuracy/precision of the pXRF machine with a reading taken at the beginning of each day". The portable XRF readings throughout the hole will be confirmed by comprehensive analysis at the laboratory. In most cases, high zinc values are usually accompanied by high germanium values. The presence of extremely high-grade barium is encouraging for the evolving geological model being adopted as learn more about the Molaoi deposit. Lithofacies modelling and laser ablation studies have both suggested that Molaoi is likely to comprise an epithermal overprint of a VMS origin. Narrow veins of elevated copper being encountered by pXRF readings in hole HMO-011 at 188.50m (0.94% Cu) and at 249.00m (0.52% Cu) support this theory. "SLR Consulting (formerly Wardell Armstrong) has been commissioned to assist tracking the current drilling program effectiveness. SLR has developed a more conservative mineralisation model which is also strongly supportive of an epithermal component to the mineralisation at Molaoi." " It is expected that drilling will continue throughout much of this calendar year. Work remains ongoing for a Hydrology Study and an Ecological Study which are both required for any future feasibility study. quotes are also being sought to commission a ground or aeromagnetic survey over the entire licence area.
