Investing.com -- Rockfire Resources PLC (LON:ROCK) said on Monday it has resumed diamond drilling at its 100%-owned Molaoi zinc deposit in Greece after the holiday break, with the fourth drill hole now completed at a depth of 250.10 meters.
The company reported that hole HMO-011, drilled in the southern part of the resource, confirmed that mineralization continues and remains open toward the south. Several narrow mineralized intervals were intersected in line with resource modeling expectations.
A 1.75-meter wide zone returned peak portable X-Ray Fluorescence (pXRF) values of 23.16% zinc, 64ppm silver, and 2.2% lead from 36.3 meters depth. Between 105.00 and 105.65 meters, readings showed 7.87% zinc, 1.2% lead, and 41g/t silver.
The company also noted a 0.65-meter interval at 127.60 meters depth containing a barium vein with average pXRF readings of 65.6% barium. This vein also hosts an average of 71.66g/t silver from four pXRF readings and will be analyzed for gold.
Rockfire emphasized that pXRF readings are preliminary, and all identified intervals will undergo comprehensive analysis at ALS Laboratories in Ireland, including testing for germanium, which is not measured by pXRF equipment.
The company is still awaiting assay results from hole HMO-010, while core from HMO-011 will soon be sent to the laboratory. A second drilling rig is expected to be provided soon by contractor Geotest Consulting Engineers.
Concurrent with drilling operations, Rockfire is conducting hydrology and ecological studies to monitor water quality and record local fauna and flora prior to any planned mining activity.
David Price, Chief Executive Officer of Rockfire, commented that the high zinc grades at the southern extremity of the modeled resource are encouraging, noting that "high zinc values are usually accompanied by high germanium values."
Price added that drilling is expected to continue throughout much of 2026, with the company seeking quotes for a ground or aeromagnetic survey over the entire license area.
