Nimy Resources Ltd (ASX:NIM) has confirmed the high-grade copper which it has previously discovered at the Masson target of its Mons project in Western Australia extends at depth, revealing this as well as cobalt and platinum group element (PGE) mineralisation within a larger zone of massive and semi-massive sulphides.
Copper grades of more than 1% have been present in all four holes in this campaign – including the fourth and deepest one – indicating Nimy is on the money with its interpretation of a high-grade copper lens with a downhole depth of 126 metres to 298 metres.
The company completed its fourth and final hole at Masson, picking up intercepts such as:
- 4.3 metres at 0.50% copper (Cu), 0.29% nickel (Ni), 0.04% cobalt (Co), 0.16 grams per tonne (g/t) 2PGE, 1.66g/t silver (Ag) (1.08% CuEq) from 295.1 metres, including 1.2 metre at 1.02% Cu, 0.04% Ni, 0.01% Co, 0.03g/t 2PGE, 3.39g/t Ag (1.12% CuEq) from 296.4 metres
- 1.3 metres at 0.38% Cu, 0.27% Ni, 0.05% Co, 0.20g/t 2PGE, 2.76g/t Ag (0.96% CuEq) from 310.4 metres
The drilling program also revealed copper – in addition to nickel, cobalt, palladium, platinum, and silver – was present within sulphide mineralisation at Masson, extending along a strike of 240 metres, and relatively thick, with a downhole width of 62 metres.
This mineralisation has been intersected from 102m to 312m downhole and remains open down dip and along strike.
Even more promising, Nimy has found copper pathfinder molybdenum of up to 804 parts per million present and above the copper lens, with soil sampling showing a 1.4 kilometre molybdenum in soil anomaly located from 700 metres south along strike of Masson.
Executive chairman Luke Hampson said the results were promising in relation to predictions for the copper lens.
“The presence of high-grade copper within the deepest hole at Masson extends the copper mineralized lens to an interpreted 186m downhole interval of greater than 1% copper,” he said.
“The copper lens remains open at depth and beyond the 240m established strike.
“A molybdenum anomaly halos the copper lens and our recent soil sampling program has highlighted a 1.4 km molybdenum in soil trend south along strike of the Masson
discovery.
“Electromagnetic anomalies run consistent with the molybdenum trend and conductor plate modelling is underway.
“Given the success at Masson we are very optimistic that the mineralisation continues south along strike and with a 3.1 km electromagnetic trend continuing north along strike to be soil sampled, Masson is shaping as a very exciting find.”
Nimy shares were trending lower after the news, and at 12:59 AEDT, they were trading at 6.8 cents – a fall of 6.85% since the market opened.
