Nimy Executive Director Luke Hampson, today said: | |
"The nickel and copper sulphides in the form of pentlandite and | |
For | chalcopyrite provide evidence of the increasingly strong prospectivity of |
Mons. The hole terminating within a komatiite flow further confirms the | |
mineralisation-hosting potential of this sparsely-explored and newly | |
discovered greenstone belt. | |
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 at 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 the Mons Project". |

Summary
Nimy Resources previously reported to the ASX (29th March 2022) that it had made a nickel gossan discovery at the Dease Prospect, within its Mons Project, centred 140 kilometres north-northwest of Southern Cross in the Central Yilgarn. The gossan was exposed when digging sumps for a planned drill programme. The portable XRF (pXRF) reported up to 0.96% Ni. Figure 1 illustrates the nature of the Dease Gossan.

As a consequence of the gossan discovery, Nimy Resources planned a follow up diamond drill hole to test for sulphide-hosted nickel mineralisation at depth and down-dip of the gossan find. The diamond drill hole (NRDD005) was completed in early July, where several zones up to four metres width of pentlandite ((Fe,Ni)9S8) (Figure 3), chalcopyrite (CuFeS2) and bornite (Cu5FeS4) mineralisation were observed (Figure 4) in the preliminary logging. Figure 2 shows oxidised ultramafic and pentlandite mineralisation in drill core respectively.

Figure 5 - NRDD005 drill cross section
The drill hole was terminated at 316 metres after drilling over 80 metres of variably serpentinised komatiite flows, which hosted the nickel sulphide (pentlandite) mineralisation. The geochemistry, as ascertained from the pXRF readings, indicates a mixed sequence of mafic and ultramafic rocks. The nickel anomalism at the Mons Project is inferred to be hosted by an 80-kilometre striking, previously unrecognised, and thus sparsely explored, Archean greenstone belt. It is inferred to be the north-north western extension of the Southern Cross Greenstone Belt that hosts the Forrestania nickel deposits.
The nickel and copper sulphide zones are generally non-coincident and the genesis of the copper sulphides remains unclear, however, it is anticipated that this will be resolved after detailed logging has been completed. Figure 4 illustrates the nature of the chalcopyrite, bornite mineralisation.
Figure 5 in cross section shows location of NRDD005 relative to the Dease gossan location.
