Rockfire Resources plc
("Rockfire" or the "Company") Confidence builds from twinned holes at Molaoi
Rockfire Resources plc (LON: ROCK), the base metal, precious metal, and critical mineral exploration company, is pleased to announce that the Company's geotechnical drilling at its 100%-owned Molaoi zinc deposit in Greece has successfully and convincingly replicated historical drill holes. This drilling was necessary to build confidence in the relative position of the historical holes and to compare the strength of mineralisation in each position. The goal is to increase the scale of the resource base and to deliver as many tonnes as possible into the higher confidence "Indicated" JORC category.
Highlights
Hole MO_GTK_008
· sited to replicate historical hole AN031. Hole MO_GTK_008 intersected 4.75m of mineralisation, which compares favourably with 5.0m of mineralisation in historical hole AN031.
· Hole MO_GTK_008 has an average grade of 8.41% Zn, which compares favourably with an average grade of 9.95% Zn in historical hole AN031.
· The highest zinc grade returned from hole MO_GTK_008 is 22.90% Zn, compared with historical hole AN031, which returned a maximum grade of 23.44% Zn.
· The highest lead interval is 3.02m @ 3.15% Pb
· The highest silver interval is 4.75m @ 64.87g/t Ag
· The highest germanium interval is 3.67m @ 46.90g/t Ge
Hole MO_GTK_009
· sited to replicate historical hole B025. Hole MO_GTK_009 intersected 2.20m of mineralisation, compared with 4.20m of mineralisation in historical hole B025. A second zone of 1.90m grading 4.05% Zn was encountered in hole MO_GTK_009.
· Hole MO_GTK_009 has an average grade of 11.20% Zn, which compares favourably with an average grade of 11.37% Zn in historical hole B025.
· The highest zinc grade returned from hole MO_GTK_009 is 25.10% Zn, compared with historical hole B025, which returned a maximum grade of 21.50% Zn.
· The highest lead interval is 1.30m @ 2.61% Pb
· The highest silver interval is 1.30m @ 73.44g/t Ag
· The highest germanium interval is 2.20m @ 30.63g/t Ge
David Price, Chief Executive Officer of Rockfire, commented:
"This replication of historical holes was requested by SRK Consulting Geologists to provide increased confidence in the positioning and grades/widths of historical drill holes. The results indicate that the similarities between the original holes and the new holes are close. The width varies in hole MO_GTK_009, however this is likely due to differences in sample lengths and sampling intervals selected. This drilling provides confidence in the original data and validates many of the historical drill holes to be included into a future resource upgrade.
"These four drill holes (MO_GTK_008 to MO_GTK_011) add confidence to the existing data, which is largely derived from historical drill holes. The results from holes MO_GTK_010 and MO_GTK_011 are awaited.
"Currently, Molaoi has an Inferred JORC resource of 250,000 tonnes of zinc equivalent metal. Our overall objective is to increase the resource and the resource category to approximately 400,000 tonnes, which would provide a 10-year mine life for a modest underground mining operation."
"Drilling is continuing at Molaoi, with the current hole (HMO_001) designed to in-fill a very large drilling gap in the resource. This is an exciting drill hole and, if successful, has the potential to add several months to the mine life of any future mining operation at Molaoi. The market will continue to be regularly informed of our progress at Molaoi."

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 Resource of 2.3 million tonnes @ 11 % ZnEq. for 250,000 tonnes of ZnEq. This resource uses a 4% low-grade cut, with individual elemental grades of 9.4 % Zn, 1.7 % Pb and 47 g/t Ag. This equates to 210,000 tonnes of zinc, 39,000 tonnes of lead and 3.5 million ounces of silver.
§ The Plateau deposit in Queensland has a JORC 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 joint venture with ASX-listed Sunshine Metals Ltd (ASX:SHN).
