Another 50m distance successfully in-filled at Molaoi

Rockfire Resources plc (LON: ROCK), the base metal, critical mineral and precious metal exploration company, provides a drilling update from Rockfire's 100%-owned Molaoi zinc deposit in Greece. Hole HMO-018 has intersected good zinc grades and successfully infills another 50m panel in the anticipated Indicated Resource model. Each hole returning good zinc, silver and germanium adds material tonnage to our targeted Indicated Resource.

Highlights

·      Diamond drilling to upgrade the Inferred Resource to Indicated Resource status continues with hole HMO-021 currently in progress.

·      Analytical results from Hole HMO-018 have arrived back from the laboratory and include:

o  3.13m @ 6.0% Zn, 52.7g/t Ag, 18.2g/t Ge and 1.5% Pb at 211.38m downhole depth

o  1.30m @ 9.1% Zn, 65.3g/t Ag, 11.3g/t Ge and 1.3% Pb from 240.70m downhole depth

o  0.91m @ 7.8% Zn, 38.0g/t Ag, 10.9g/t Ge and 2.0% Pb from 270.49m downhole depth

·      Results from the laboratory for drill holes HMO-019 and HMO-020 are awaited.

·      Portable XRF readings from hole HMO-020 include:

o  Peak individual values of 37.7% and 29.6% Zn

o  Peak individual silver values including 100g/t Ag

o  Peak individual readings up to 8.6% Pb

o  0.85% Cu is the highest individual copper reading so far

     The pXRF does not measure germanium.

The cleanliness of the pXRF machine is 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) is measured for accuracy/precision of the pXRF machine with a reading taken at the beginning of each day.

·      Our drilling contractor in Athens has informed Rockfire that the intended summer vacation for their drilling crews throughout Europe will occur during the second half of August, during which there will be no drilling activity.

David Price, Chief Executive Officer of Rockfire, commented:

"Results from Hole HMO-018 successfully infills another 50m panel both laterally and vertically. Each hole which returns good zinc, silver and germanium adds material tonnage to our targeted Indicated Resource. This interval of 3m @ 6% Zn, 52g/t Ag and 18g/t Ge is positioned halfway between holes HMO-015 (12m @ 8.8% Zn, 49g/t Ag, 25.2g/t Ge) and HMO-017 (5.9m @ 5% Zn, 20.5g/t Ag, 16g/t Ge). The completion of an Indicated Resource is part of our scheduled feasibility study into economic extraction of zinc, silver, germanium and lead at Molaoi.

The Company has commenced fast-tracking several technical aspects of the feasibility study for Molaoi. Quotes are being obtained to undertake studies to apply for permits to reopen the underground workings for future mining use. These studies include drilling several holes into the path of the existing decline to determine geotechnical conditions to ensure a safe mining plan. It is expected that studies will commence this calendar year and are expected to take approximately 4 months to complete.

The Company is expecting the completion of field observations as part of an Ecological Study in the coming weeks, with a final report expected in August. Hydrological observations are still being recorded as part of the baseline Hydrology measurements prior to mining.

The Company has been notified that at this point in time our drilling rig remains on schedule for landing into Athens in late September/early October as originally scheduled.

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