Rockfire Resources (LSE:ROCK) has restarted diamond drilling at its 100%-owned Molaoi zinc project in Greece following a scheduled summer break.
Diamond drill hole HMO-021 is currently in progress as the company continues its exploration programme at the deposit.
Rockfire is also recruiting drillers and drilling assistants for its Greek subsidiary, Hellenic Minerals S.A. The recruitment is intended to provide additional in-house drilling capacity for work planned later in the year.
Preliminary Comminution Testing Completed
Rockfire has also reported preliminary results from comminution testing undertaken by SLR Consulting on material from Molaoi.
The tests classified the material as medium-hard and found that its energy requirement falls within the range typically encountered in mining projects, according to the company.
The results are being used as part of Rockfire’s assessment of processing options for the project.
SAG Milling Under Consideration
Based on the preliminary test results, Rockfire is considering the potential use of semi-autogenous grinding, or SAG milling, rather than conventional ball milling.
The company is evaluating this option as part of its processing flowsheet design and feasibility work for Molaoi. No final processing configuration has been confirmed in the supplied information.
