Nimy Resources’ search for copper and nickel hits breakthrough

A DHEM survey completed to a depth of 444m uncovered the results and suggests the anomaly could be a source of the copper, nickel and PGEs found in shallow drilling nearby.

The scale and conductivity of the EM targets suggest Nimy (ASX:NIM) may be on the verge of extending the known copper-nickel system well beyond its current limits at Masson.

Earlier drilling intersected highly anomalous copper, nickel, and PGE sulphide mineralisation between 91m and 288m.

But the newly identified upper plate suggests mineralisation continues to 340m, while the lower plate extends the highly conductive trend an additional 100m.

The high conductive trend is plunging to the south towards a high magnetic anomaly identified from VOXI depth slice modelling, representing a possible source of the Masson mineralisation.

A third, lower-confidence plate surrounding Plate A was modelled with a much lower conductance of 350 Siemens and may indicate a broader, lower conductance copper mineralised zone.

Plates have been modelled to the limit of survey data collected, meaning that the mineralisation remains open at depth below the lower plate.

NIM managing director Luke Hampson said these latest geophysics results provide more strong evidence of the potential for a significant body of high-grade copper-nickel at Masson.

Masson is one of several prospects within the wider Mons project, a district-scale opportunity spanning ~3004km2 of the Forrestania greenstone belt near Southern Cross in WA.

The asset offers multi-commodity potential with the discovery of Masson (copper, nickel, cobalt, gold and PGEs) in addition to the Block 3 prospect. That discovery hosts high-grade gallium in the northern tenements of the Mons project.

Nimy now has three key pieces of firm evidence including known shallow mineralisation, with three nearby connected conductive plates vectoring toward a large magnetic anomaly.

“This survey has successfully expanded the footprint and indicates a substantial accumulation of copper dominant massive sulphide mineralisation,” Hampson said.

“Masson is the first of many targets generated from our large-scale VTEM survey to be drilled and Nimy technical geologist is interpreting and prioritising a number of possible repeats of the Masson discovery.”
