Intercepts continue to build tonnes at Molaoi

Rockfire Resources plc (LON: ROCK), the base metal, critical mineral and precious metal exploration company, provides an update of development activities from Rockfire's 100%-owned Molaoi zinc deposit in Greece. Hole HMO-020 has returned multiple high-grade zinc and germanium intersections.

Highlights

·      Diamond drilling to upgrade the Inferred Resource to Indicated Resource status continues with hole HMO-021 in progress, though temporarily suspended during the summer vacation period.

·      Comminution tests (crushing & grinding) are in progress to determine the appropriate equipment for use at Molaoi, as well as power expectations.

·      Point load compressive tests are also underway to determine the ability of the ground to withstand compressive forces once a void is created during underground mining.

·      Analytical results from Hole HMO-020 have been received from the laboratory and include:

o  2.34m @ 6.2% Zn, 20.2g/t Ag, 15.1g/t Ge and 0.3% Pb from 215.60m downhole depth

o  2.86m @ 4.1% Zn, 24.5g/t Ag, 9.3g/t Ge and 1.2% Pb from 240.04m downhole depth.

o  2.23m @ 5.2% Zn, 24.4g/t Ag, 4.1g/t Ge and 0.7% Pb from 248.12m downhole depth

David Price, Chief Executive Officer of Rockfire, commented:

"Hole HMO-020 was designed to test the same section as holes HMO-015 and HMO-021 (in progress). This aim was successfully achieved, with multiple intersections being encountered. Each successful hole is expected to add to the overall tonnage of our targeted Indicated Resource.

Samples of core have now been delivered to the laboratory at SLR Consulting to undertake comminution tests (crushing & grinding) to determine the appropriate equipment for use at Molaoi. This work will include point load tests to determine the ability of the ground to withstand compressive forces once a void is created during underground mining.

The Company is investigating metallurgical testing options and is in discussion with several groups to conduct flotation tests, smelting of a zinc ingot and production of a germanium product as part of our feasibility pathway.

The market will continue to be informed and updated as we advance the Molaoi Project."

·      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).
