Rockfire Resources PLC has resumed diamond drilling at the Molaoi zinc deposit in Greece following a holiday pause, reporting the completion of its fourth drill hole to a depth of 250.10 meters.
The company identified the hole as HMO-011, sited in the southern portion of the resource model. Rockfire said the hole confirmed that mineralization persists in that direction and remains open towards the south. Multiple narrow mineralized intervals were intersected, consistent with the company's resource model expectations.
Among the notable preliminary pXRF readings, a 1.75-meter interval beginning at 36.3 meters returned peak values of 23.16% zinc, 64ppm silver, and 2.2% lead. Another interval between 105.00 and 105.65 meters registered pXRF readings of 7.87% zinc, 1.2% lead, and 41g/t silver.
Rockfire also reported a 0.65-meter zone at 127.60 meters that contains a barium vein. Average pXRF readings for that vein were 65.6% barium, and the vein produced an average of 71.66g/t silver from four pXRF measurements. The company said the barium vein will be analyzed for gold as part of laboratory testing.
Rockfire emphasized that the pXRF results are preliminary. All intervals identified by field measurement will be submitted for comprehensive laboratory analysis at ALS Laboratories in Ireland, where full assays will include elements not measured by pXRF instruments, such as germanium. The company is still awaiting final assay results from hole HMO-010; core from HMO-011 will be dispatched to the lab in due course.
Operationally, Rockfire expects to expand its drilling capability: a second drilling rig is anticipated to be supplied soon by contractor Geotest Consulting Engineers. Management said drilling activity is planned to continue through much of 2026, and the company is seeking quotes for either a ground or aeromagnetic survey covering the entire license area.
In parallel with drilling, Rockfire is carrying out hydrology and ecological studies at the project. These baseline programs are designed to monitor water quality and document local fauna and flora ahead of any potential mining activity.
Chief Executive Officer David Price characterized the elevated zinc values encountered near the southern edge of the modeled resource as encouraging, and he noted that "high zinc values are usually accompanied by high germanium values." Beyond the field program, the company is moving forward with geophysical survey planning to support its exploration work.
Context and next steps
Rockfire's immediate priorities are laboratory assays for the recently drilled holes, maintaining drilling through 2026, and implementing broader geophysical and environmental programs across the license area. The company has signaled that final assay results and further drilling updates will determine subsequent exploration and assessment work.
