("Rockfire" or the "Company")Massive sulphides hit at predicted depth at Molaoi

Rockfire Resources plc (LON: ROCK), the gold, base metal and critical mineral exploration company, is pleased to announce that inaugural drilling has encountered massive sulphides at the predicted depth and position at its 100%-owned Molaoi zinc/silver/lead/germanium deposit in Greece ("Molaoi").

Highlights

· Both massive and semi-massive sulphides have been encountered in Rockfire's first drill hole at a depth and position predicted from historical drill data.

· Between 1979 and 1988, 173 diamond drill holes were drilled at Molaoi, as well as metallurgical tests, a feasibility study and the development of a portal and decline to the orebody. The Company's exploration and exploitation permit allows Rockfire to capitalise on this excellent work by the Greek Government to help monetise the project in a timely manner.

· The current, first hole (MO_GTK_001) lies between historical drill holes and will serve to provide core for geotechnical test work to feed into a feasibility study.

· To encounter massive and semi-massive sulphides at the predicted depth and position verifies the historical drilling and validates the countless hours of mineralisation modelling completed by the Rockfire team.

· Massive sulphides occur between 130m and 134m, with semi-massive and disseminated sulphides continuing for a further 11m, down to 145m. More disseminated sulphides have also been encountered at 160m depth, which may represent a parallel lode beneath the main lode.

· A second, parallel lode is predicted, and drilling of this inaugural hole is being deepened, to test for this second lode.

· The core is demonstrating important zonation. As the orebody is approached in the drill hole, epidote veining alteration gives way to a broad zone of intense, ubiquitous chlorite alteration. Even closer to the orebody, alteration changes to kaolinite (clay), then finally a subtle sericite alteration at the very edges of the mineralisation. This is an excellent observation by the Company's technical team and assists with the prediction of proximity to lodes in each hole. 

· It is expected that sufficient mineralised core will be obtained to commence crushing and grinding work index studies. These studies determine the energy (and therefore cost) required to crush and grind the mineralised rock. The results from these studies are parameters required for technical and financial feasibility studies, which Rockfire plans to commence as soon as possible.

· Drilling remains in progress but is slow due to strongly brecciated, highly veined, broken and extremely altered rock; which are all excellent indications for favourable mineralisation.

David Price, Chief Executive Officer of Rockfire, commented:

"This drilling is providing important geotechnical information for our team. In particular, the intensely broken, veined, brecciated and altered nature of the rocks is an excellent structural setting for mineralisation. This geotechnical information will aid in mine design, expected ground conditions for an underground mining operation, as well as support and safety requirements to ensure a safe mine.

"The visible mineralisation appears to adhere well to the expected behaviour recorded in historical drilling. The massive sulphide zone tends to be around 3.0m average width and usually carries very high-grade zinc, lead, silver (+/- germanium) in historical core. This is accompanied by a broader zone of semi-massive sulphides beneath the massive sulphides, with slightly lower grades for at least another 10m downhole.

"The market will be informed regularly as our drilling programme progresses"
