Systematic exploration activities have been conducted at Mahefedok since 2014 and results obtained from exploration work (including geological mapping, ground geophysical surveys, pitting, trenching and sampling), confirmed that Mahefedok contained significant regolith-hosted flake graphite mineralisation over approx. 1.8 km in strike length.
Trial mining commenced in early January 2016 at the northern extension of the Mahefedok Deposit, and to date a total of ~10,000 tonnes of material has been mined, with product sold to existing customers of Graphmada.
In late 2016, after Bass Metals took full operational control of Graphmada, a first pass maiden 2,300 metre diamond-drilling program at Mahefedok was completed and identified significant intercepts of soft easily mineable saprolite mineralization. All drill holes demonstrated graphite mineralization.
The program delivered a Maiden Mineral Resource of 3.5 Mt at 4.2% Total Graphitic Carbon (TGC) at Mahefedok, immediately adjacent to existing Graphmada Mine infrastructure. These resources supplement Graphmada’s Indicated and Inferred resources at Loharano of 5.7Mt @ 4.1% TGC for supply to existing processing facilities and as a basis for expansion to 20,000 tonnes per annum (tpa).
Mahefedok Mineral Resources are reported in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (‘the JORC Code 2012’).
