Molaoi Drilling Update
Rockfire Resources plc (LON: ROCK), the base metal, critical mineral and precious metal exploration company, provides the market with a drilling update from Rockfire's 100%-owned Molaoi zinc deposit in Greece.
Highlights
· 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:
o 0.76m @ 22.4% Zn, 187g/t Ag, 8.8% Pb and 34.6g/t Ge at 314.18m downhole depth.
o 1.08m @ 8.2% Zn, 42.5g/t Ag, 1.6% Pb and 22g/t Ge from 407.11m downhole depth
o 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:
o Peak individual values of 47.2% Zn and 46.5% Zn
o Peak individual readings up to 5.3% Pb
o Peak individual silver values including 168g/t Ag and 121g/t Ag
o 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.

David Price, Chief Executive Officer of Rockfire, commented:
"Strong analytical results from hole HMO-016, together with high grade pXRF results from holes HMO-017 and HMO-018 continue to build the case for a successful upgrade to the Indicated category.
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.
Some of the conclusions in their latest report include:
· 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.
We will continue to keep the market informed and updated as new information and analytical results become available."

Notes to Editors
Rockfire Resources plc (LON: ROCK) is a gold, base metal and critical mineral exploration company, with a high-grade zinc/lead/silver/germanium deposit in Greece and a portfolio of gold/copper/silver projects in Queensland Australia.
· 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.
· The Plateau deposit in Queensland has a JORC Inferred Resource of 131,000 ounces of gold and 800,000 ounces of silver, using a 0.5g/t Au cut off. 53,000 of these ounces lie within the top 100m from surface. Plateau is subject to a farm-in by ASX-listed Sunshine Metals Ltd (ASX:SHN).
· The Marengo prospect in Queensland hosts high-grade gold, silver and copper within an historic goldfield, which is entirely under licence by Rockfire. Marengo is subject to a farm-in by ASX-listed Eastern Resources Ltd (ASX:EFE).
