Rockfire Resources has intersected high-grade zinc and germanium mineralisation at its Molaoi project in Greece, advancing exploration of a deposit that could potentially supply Europe with both base metals and a strategically important industrial raw material.
Drill hole HMO-021 returned 11 metres grading 5.0% zinc, 19 grams of silver per tonne and 8 grams of germanium per tonne. Within this interval, a 1.4-metre section graded 18.1% zinc and 20.5 g/t germanium. A narrower 0.34-metre interval also returned particularly high zinc grades, although the short intersection is not representative of the entire deposit. The latest results extend previously identified mineralisation and support the company’s work towards its first JORC-compliant germanium resource estimate.
Germanium potential and European supply security
Germanium is used in fibre optics, infrared systems, semiconductors, solar technologies and defence applications and is classified by the EU as a strategic raw material. Europe remains heavily dependent on imported germanium and external processing capacity.
Recoverable germanium as a by-product of zinc production could strengthen Molaoi’s potential economic value and relevance to European supply chains. However, Rockfire has not yet published its planned germanium resource estimate.
Further drilling and metallurgical assessment
Rockfire plans additional drilling, with another rig expected to arrive in Greece in November. The programme is intended to assess the continuity and extent of germanium mineralisation and determine whether it could contribute materially to future project revenue.
Metallurgical work will also be necessary to establish germanium recovery rates, concentrate specifications and viable downstream processing routes. The presence of germanium does not by itself establish that the metal can be recovered economically.
Project remains at the exploration stage
Molaoi’s location within the EU could offer access to European industrial partnerships and potential public-sector support if the project advances. However, its development prospects depend on converting exploration results into a defined resource, demonstrating recoverability and establishing an economic mine plan.
Rockfire has not announced a final feasibility study, mine-construction decision, binding industrial offtake agreement or new project-financing package. The latest drilling therefore represents a resource-definition milestone, rather than a financing or mine-development decision.
