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

· Drilling of hole HMO-009 has temporarily ceased. This is the second drill hole of the recently commenced resource upgrade to Indicated status.

· Drilling of hole HMO-009 was suspended at a depth of 75.00m, with the target mineralisation at +250m depth. The hole is dominated by extensive fault zones, shears, brecciation and fracturing, which resulted in extremely difficult drilling conditions.

· A decision was made to cease drilling hole HMO-009, secure the hole for re-drilling later, and to move to the next drill hole.

· There are another 28 holes to be drilled in this drilling campaign and re-drilling of challenging holes, including hole HMO-009, will occur at the end of the drill program.

· Hole HMO-008, which was terminated prematurely in one of the growth faults intersected a lode high in the hole at 69.71m. This interval is 0.2m @ 22.2% Zn, 16.2g/t Ge, 2.9% Pb, and 100.0g/t Ag.

· The drill rig has moved to the third hole site, (HMO-010) and early signs of mineralisation are good (see photo below), with massive sulphides encountered at a depth of 44.20m.

A narrow, but strongly mineralised massive sulphide vein encountered early in hole HMO-010, at 44.20m depth. The target to the main lode of mineralisation is 250m below the surface. Drilling continues, with this hole already at 75.60m depth in better ground conditions.

David Price, Chief Executive Officer of Rockfire, commented:

"Our second drill hole has also proved extremely difficult to drill. A rapid decision was made to suspend drilling of this hole and to move to the third hole for the sake of increased drilling productivity. Holes HMO-008 and HMO-009 have been secured, plugged and left ready to move the rig back onto these holes to continue drilling them later."

"Early signs of massive sulphide mineralisation in hole HMO-010 is pleasing. These upper lodes represent some of the more distal veins, with the main mineralisation being below a level of 250m from surface. Drilling is progressing well in this hole, and we anticipate better ground conditions."

"A second drill rig is being sought to increase the rate of drilling productivity and we expect that rig to be available in early January 2026. We will continue to update the market as our drilling continues."
