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. Announcement • 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.
