Molaoi Inferred Germanium Estimate Underway
Rockfire Resources plc(LON: ROCK), the base metal, critical mineral and precious metal exploration company, is pleased to provide the market with this drilling and operational update from Rockfire’s 100%-owned Molaoi zinc deposit inGreece.
Highlights

A 1cm wide vein of massive copper (chalcopyrite) at 179.80m depth, with a single pXRF reading of 12% Cu will provide directional information towards the source of mineralisation at Molaoi.
The cleanliness of the pXRF machine was 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 (OREAS 620) was measured for accuracy/precision of the pXRF machine with a reading taken at the beginning of each day. pXRF readings are preliminary and indicative only, and are not a substitute for laboratory assays. Laboratory analysis will be undertaken in due course.

David Price, Chief Executive Officer of Rockfire, commented:
“It is both exciting and significant to have the highly anticipated maiden germanium resource for Molaoi underway. The process involves a re-modelling of the main zinc lodes with the inclusion of germanium grades. Germanium grades are being collated from re-sampling historical core, the ongoing systematic analytical work being done during past and current drilling programmes and extrapolation of grades from regression mapping of historical zinc grades.
On the announcement of the germanium inferred resource, Molaoi will host only the second quoted germanium resource globally, excluding China, demonstrating the significance of the Molaoi project to global germanium supply chains. With reverse parking sensors in cars, artificial intelligence and precision weaponry dependent on germanium supply, Rockfire anticipates increasing demand for germanium over the coming decades.
The intersection of the highest copper value ever recorded at Molaoi is exciting. In most mineral systems of this type, it is expected that copper values will increase as the proximity to the mineralising heat source approaches. We believe that the narrow intercept is of no concern as the important aspect of this interval is the extremely high grade. This shows the temperature/acidity/pressure conditions are favourable for precipitation of copper. This is a distinct change from other parts of the deposit.
The market will continue to be informed and updated as we advance the Molaoi Project.”
