Nimy Resources Ltd (ASX:NIM) confirmed the discovery of significant nickel, copper, cobalt and PGE’s within sulphide mineralisation at the Block 2 prospect in WA. The discovery has been named the Masson Prospect.
Drill targets including new high conductance plates modelled from the DHEM are being readied for follow up drilling.
Geophysics
- Downhole electromagnetic (DHEM) survey completed on hole 23NRRC0100 has resulted in 3 additional conductive plates modelled within and off the hole
- Fixed loop electromagnetic (FLEM) survey completed at the Masson Prospect indicate the mineralized sulphide zone is within a large (550m long x 175m wide) EM anomaly – indicating potential for the Masson discovery to be a large, massive nickel-copper sulphide deposit.
Geochemical Assays
- The first hole – the discovery intersection – reverse circulation hole (23NRRC0100) intersected 10 metres of disseminated to massive style sulphide mineralisation:
- 10m from 98m @ 0.42% nickel, 0.39% copper, 0.04% cobalt and 0.32g/t PGE’s (Pt, Pd) including 5m @ 0.73% nickel, 0.53% copper, 0.06 % cobalt and 0.55g/t PGE’s (Pt Pd) from 102m.
- Follow up diamond hole (23NRDD008) – intersected a 54-metre sulphide mineralised zone from 126m as predicted by the EM model, assay highlights include:
- 5.5m from 126.5m @ 0.36% nickel, 0.27% copper, 0.04% cobalt and 0.25g/t PGE’s (Pt, Pd) including 2m from 130m @ 0.66% nickel, 0.42% copper, 0.07% cobalt and 0.57g/t PGE’s (Pt, Pd) and 1m from 130m @ 0.81% nickel, 0.46% copper, 0.07% cobalt and 0.53g/t PGE’s (Pt, Pd)
- 2m from 136.5m @ 0.37% nickel, 1.07% copper, 0.07% cobalt and 0.27g/t PGE’s (Pt, Pd) including 1m from 137m @ 0.40% nickel, 1.49% copper, 0.10% cobalt and 0.29g/t PGE’s (Pt, Pd) and 0.5m from 137m @ 0.35% nickel, 2.05% copper, 0.17% cobalt and 0.33g/t PGE’s (Pt, Pd)
- The mineralisation continues to 171.5m and also contains elevated values of cobalt and platinum group metals (PGM’s)
The Masson Prospect is in a previously unexplored, difficult to access area covered by transported overburden, and was discovered with the first reverse circulation hole designed to intersect and test two potential electromagnetic conductors at the Masson (Block 2) Prospect.The extension of sulphide mineralisation including massive sulphides hosted within a mafic rock type, within a large electromagnetic anomaly, along a contact zone gives Nimy an excellent opportunity to discover a substantial nickel copper deposit at the Masson Prospect located within a previously underexplored and new greenstone belt,” Executive Director Luke Hampson said.
“Our exploration strategy and exhaustive work coupled with the excellent work delivered by Resource Potentials enables us to zero in on not only the Masson Prospect, but the additional targets identified using the same geophysical surveys process.
“The Masson prospect is a significant breakthrough for Nimy Resources as we move toward establishing the Mons Project as a fertile exploration holding.”
Next Steps
- Planning and approvals for the next drill campaign to test a pipeline of EM targets and progress the large Masson Prospect – FLEM target.
- Full interpretation of the 175m x 550m – FLEM anomaly at the Masson Prospect.
- Interpretation of mineralogy from the Masson Prospect massive sulphide petrology.
