Rockfire Resources Provides Drilling Update for Molaoi Zinc Deposit 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-019 currently in progress. Analytical laboratory results from hole HMO-016 include: 0.76m @ 22.4% Zn, 187g/t Ag, 8.8% Pb and 34.6g/t Ge at 314.18m downhole depth; 1.08m @ 8.2% Zn, 42.5g/t Ag, 1.6% Pb and 22g/t Ge from 407.11m downhole depth; 4.5m @ 3.0% Zn, 20.7g/t Ag, 0.9% Pb and 20g/t Ge from 417.95m downhole depth. Results from the laboratory for drill holes HMO-017 and HMO-018 are awaited. Portable XRF readings from hole HMO-018 include: Peak individual values of 47.2% Zn and 46.5% Zn; Peak individual readings up to 5.3% Pb; Peak individual silver values including 168g/t Ag and 121g/t Ag; 0.76% Cu is the highest individual copper reading. The pXRF does not measure germanium. 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) is measured for accuracy/precision of the pXRF machine with a reading taken at the beginning of each day. Multiple drill holes are being drilled from the same position, but with differing angles to intersect the mineralisation at varying depths. This is designed to help in-fill between existing drill holes vertically, as well as laterally. SLR Consulting is closely monitoring our drilling program and continues to provide dynamic updates on the exploration database, the mineralisation model, the lithofacies model and the base of oxidation model. The updated drill hole master files were imported into the 3D mining software, Leapfrog, and reviewed for errors. In general, the drill hole files were error-free and in good shape. The oxide model was updated with the oxide logging from the new drill data, resulting in minor thickness changes to oxide and transition domains in the southern and central resource areas. The lithofacies model was updated, which showed that although the volcaniclastic packages can be modelled along the strike of the known deposit, new logging suggests the geometry of the packages pinches and swells with short-scale variation in thickness. pXRF data in HMO-015 suggests the main mineralised lodes are deeper than previously interpreted and have been potentially offset. pXRF data in HMO-016 show that mineralised zones are continuous down dip but are thin. 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. Announcement • May 30

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.
