Nimy Resources (ASX: NIM) has intersected high-grade copper-nickel-cobalt-platinum group elements (PGE) mineralisation in massive and semi-massive sulphides at the promising Masson discovery within its flagship Mons nickel project in Western Australia.

Assays from drilling three holes show a broad zone containing an interpreted high-grade copper lens of up to 236 metres depth, with all holes returning grades of more than 1% copper.

The mineralised zone at Masson is now believed to extend along a strike of 240m with a maximum down-hole width of 61.5m and has been encountered from 102m to 328m down-hole, remaining open down dip and along strike.

Drilling highlights

Best result from the first hole was 13m at 0.62% copper, 0.36% nickel, 0.04% cobalt, 0.25 grams per tonne PGE (platinum and palladium) and 2.30g/t silver (1.33% copper equivalent, or CuEq) from 126m including 2m at 1.05% copper, 0.15% nickel, 0.03% cobalt, 0.14g/t PGE and 5.28g/t silver (1.38% CuEq) from 126m.

The second hole’s best return was 5.58m at 1.27% copper, 0.42% nickel, 0.06% cobalt, 0.32g/t PGE and 4.32g/t silver (2.13% CuEq) from 230.52m including 1.28m at 0.15% copper, 0.87% nickel, 0.06% cobalt, 0.63g/t PGE and 1.14g/t silver (1.78% CuEq) from 230.52m.

Best assay from the last hole was 11m at 0.36% copper, 0.21% nickel, 0.02% cobalt, 0.15g/t PGE and 1.31g/t silver (0.77% CuEq) from 176m, including 1m at 0.19% copper, 0.64% nickel, 0.04% cobalt, 0.41g/t PGE and 0.16g/t silver (1.38% CuEq) from 181m.

Significant discovery

Nimy executive director Luke Hampson said the results confirm Masson to be a significant discovery.

“Hosted within mafic intrusive rocks, the emergence of copper at these levels particularly as we drill deeper signifies a dynamic system which could be part of a much larger mafic intrusion,” he said.

“Further exploration will include testing of coincident high magnetics and electromagnetic (EM) anomalies along the 3.1km northern strike that begins with the Masson discovery and the 3.8km highly magnetic unit with coincident EM anomalies to the south-west.”
