Molaoi Drilling Update

Rockfire Resources plc (LON: ROCK), the base metal, critical mineral and precious metal exploration company, provides the market with this drilling update from Rockfire's 100%-owned Molaoi zinc deposit in Greece.

Highlights

· The drill rig remains on the third hole site, (HMO-010) and drilling continues to progress well. Early on Monday the 8th of December, the drill hole is at 140.00m depth.

· At the completion of this current drilling campaign, it is expected that Molaoi will host the only defined Inferred Resource of germanium in Europe and one of only two quoted germanium resources globally.

· Massive sulphides are being encountered in hole HMO-010 at the predicted depths in accordance with the resource model.

· pXRF results so far in hole HMO-010 are reading high grades of zinc, silver, and lead. Between 97.55m and 98.20m depth, individual spot readings peak at 13.9% Zn, 1.48% Pb and 133ppm Ag. The pXRF equipment does not measure germanium values, but germanium will be analysed at the laboratory.

· The main target lodes lie beneath the current drill depth with 200m being the top of the target zone for mineralisation.

· Our objective to increase the zinc/silver/lead resource confidence from Inferred to Indicated continues and drilling is expected to continue throughout the first half of 2026.

· Long lead-time components of our planned pre-feasibility study have now been commissioned. A Hydrology Study and an Ecological Study have now commenced. Such long lead-time aspects of the pre-feasibility require a minimum of 12 months of baseline monitoring and measurements. Rockfire has commissioned these early to ensure a timely completion of all the studies required prior to mining.

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.

David Price, Chief Executive Officer of Rockfire, commented:

"Our third drill hole is encountering improved ground conditions. The rig is 672m south of hole HMO-008, and 396m south of hole HMO-009, where broken and fractured ground created difficult drilling conditions in both holes. It should be kept in mind that the zinc resource is 2.2km long so far and there are still 28 holes to be drilled within this resource distance."

"We will continue to update the market as our drilling continues."
