Nimy Resources intersects semi-massive nickel-copper zones at Mons project

Exploration at Nimy Resources’ (ASX: NIM) Mons project near Southern Cross in Western Australia has intersected semi-massive nickel-copper sulphides within the Dease gossan.

Down-dip diamond drill testing revealed several mineralised zones up to 4m in width including pentlandite, chalcopyrite and bornite, hosted by ultramafic (including komatiite) and mafic rocks.

Strongly anomalous levels of cobalt were also detected using portable xray fluorescence (pXRF).

Dease discovery

Nimy exposed the Dease nickel gossan in March, during construction of a diamond drilling sump.

It returned a peak pXRF reading of up to 0.96% nickel.

In June,  the company reported the first hole at Dease had intersected copper, nickel and zinc followed by a 487m nickel-copper ultramafic zone.

Follow-up drilling to test for sulphide-hosted mineralisation at depth and down-dip of the gossan was completed earlier this month and identified pentlandite, chalcopyrite and bornite in preliminary logging.

The zones are generally non-coincident and the genesis of the copper sulphides remains unclear.

Nimy anticipates this will be resolved after detailed logging has been completed.

Strong prospectivity

Executive director Luke Hampson said the new nickel-copper sulphide zones provide evidence of the Mons project’s “increasingly strong” prospectivity.

“The hole terminating within a komatiite flow further confirms the mineralisation potential of this sparsely-explored and newly discovered greenstone belt,” he said.

“Ongoing drilling is now planned to follow up other known anomalous surface nickel, cobalt and copper assays, complemented by down hole geophysical survey analysis.”

The surface of the Dease prospect primarily comprises sand plain with few outcropping rocks.

“The importance of now being able to correlate any surface anomalism with potential nickel-copper mineralisation at depth cannot be underestimated and is an exciting development going forward for Mons,” Mr Hampson said.

Additional outcrops

Prospecting by Nimy’s team has since identified additional gossan outcrops which, when added to previous soil and drill results, identifies significant nickel-copper-cobalt anomalism up to 5km north and 10km south along strike of Dease.

Mr Hampson said the coinciding gossan identification, geophysics, soil geochemical anomalies, core visual and pXRF results would enable a better understanding of the significance of the gossan finds.
