Neometals Ltd (ASX: NMT) has announced mineral resource upgrades for its McEwen and McEwen Hangingwall deposits within the Mt Edwards Project in Western Australia.
3.049 million tonnes at a grade of 1.4% Ni…This represents a 45% increase in contained nickel
- Re‐interpreted and re‐estimated McEwen and McEwen Hangingwall mineral resources now stand at 3.049 million tonnes at a grade of 1.4% Ni for 41,500 contained nickel tonnes. This represents a 45% increase in contained nickel.
- Updating of the mineral resource estimates at the McEwen and McEwen Hangingwall deposits has expanded the global Mt Edwards Project mineral resource to 9.64 million tonnes @ 1.7% nickel for 160,000 tonnes of contained nickel across 11 deposits.
- The company also downgraded its Zabel Mineral resource, with the revised resource now standing at 325,000 tonnes @ 2.0% nickel for 6,360 tonnes of contained nickel, a reduction of 7%.
Mt Edwards Project Nickel Mineral Resources total is as shown below.
Mt Edwards project
NMT’s fully-owned Mt Edwards Project comprises tenements covering an area of 240km² in an historic nickel sulphide belt, 40km south of Mt Marion and 35km west of Kambalda in Western Australia. The project is located in an area rich with historic nickel sulphide mines near the town of Widgiemooltha.
The Mt Edwards project encompasses eleven nickel deposits. The McEwen and McEwen Hangingwall deposits are two discrete mineral resources approximately 250 metres apart and are closely associated with the Zabel deposit located 350 metres to the north.
Re‐estimation of McEwen deposits
The re‐estimation of the McEwen and McEwen Hangingwall mineral resources was a continuation of a major review of the Mt Edwards project. The re-estimated McEwen and McEwen Hangingwall inferred mineral resource estimates are shown below.
The reinterpreted mineral resource estimates for McEwen and McEwen Hangingwall have increased the tonnage and grade of both deposits, with a combined total of contained nickel now at 41,450 tonnes up from 28,220 tonnes.
NMT’s future work program planned for McEwen and McEwen Hangingwall will include RC and diamond core drilling to further assess the extent of mineralisation, along with improving the understanding of the metallurgical characteristics to pave the way for mining studies.
Further drilling, sampling, and DHEM geophysics have been planned by NMT to test the potential lateral extents and infill areas for nickel mineralisation. Further metallurgical test work has also been planned to improve the understanding of the nickel mineralisation and its amenability to extraction.
