Rockfire Resources (AIM:ROCK), the base metal, critical mineral and precious metal explorer, said Hole HMO-018 at its 100%-owned Molaoi zinc deposit in Greece has infilled another 50-metre panel in the anticipated indicated resource model.
The hole returned 3.13 metres at 6.0% zinc, 52.7 grams per tonne silver, 18.2 grams per tonne germanium and 1.5% lead from 211.38 metres downhole, alongside two further high-grade intervals down to 270.49 metres.
Diamond drilling to upgrade Molaoi's inferred resource to indicated status continues, with Hole HMO-021 now in progress and lab results for HMO-019 and HMO-020 still pending.
Portable XRF readings from HMO-020 showed peak individual values of 37.7% and 29.6% zinc and up to 100 grams per tonne silver, though the technique does not measure germanium.
Molaoi carries a JORC inferred resource of 15.0 million tonnes at 7.26% zinc, 1.75% lead and 39.50 grams per tonne silver, equivalent to 1.5 million tonnes of zinc-equivalent metal.
Rockfire has begun fast-tracking feasibility work, including geotechnical drilling to assess reopening Molaoi's underground workings, expected to start this year and take roughly four months.
An ecological study report is due in August, and the company's drilling rig remains on schedule to land in Athens in late September or early October.
"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," said David Price, Rockfire chief executive.
