CORPORATE JAMES PROSPECT

The Corporate James prospect sits within the eastern margin of the Mons Greenstone Belt (MGB), along a structural corridor where Archaean greenstones meet younger granites to the east. Soil sampling across the Mons Project has identified multiple parallel, north-south trending gold anomalies along this contact zone, with pathfinder elements arsenic, antimony, bismuth, molybdenum, silver, tellurium and tungsten confirming the prospectivity of the system.

The Discovery

  • Re-interpretation of regional geology and remote sensing data identified Archaean greenstone belts extending more than 75 kilometres within the Mons Project tenements, highlighting strong potential for greenstone-hosted orogenic and intrusion-related gold deposits typical of the Yilgarn Craton.
  • An extensive Ultrafine™ regolith soil sampling programme was designed to systematically test gold-in-soil anomalism across the project; assays from 9,222 samples have now been received, with a further 7,000+ samples in progress.
  • Multi-element gold and pathfinder anomalies were identified along a strike length of over 16 kilometres, parallel to the eastern granite-greenstone contact of the Mons Greenstone Belt.
  • Corporate James was identified and named as the highest-priority prospect within the trend, where the anomalous envelope spans 720 metres north–south by up to 350 metres east–west.
  • The anomalies are located in areas of residual soil, defined through the Nimy-sponsored CSIRO Landscape+ remote regolith mapping programme, supporting the reliability of the geochemical signal.

The Soil Sampling Programme

  • Geochemical assays from 9,222 samples confirm coherent, anomalous gold-in-soil across the Corporate James Trend, with coincident elevated concentrations of arsenic, antimony, bismuth, molybdenum, silver, tellurium and tungsten – a multi-element signature consistent with orogenic gold and intrusion-hosted gold systems.
  • The residual regolith anomalies align with the overall NNE-SSW structural strike of the Mons Greenstone Belt, with secondary orientations attributed to splay faults and shears inferred as potential gold hosts.
  • Previously explored only for komatiite-hosted nickel, these results confirm the gold prospectivity of the eastern MGB margin for the first time.
  • A total programme of more than 16,000 soil samples is underway across the Mons Project tenements, with Priority 2 targets at Masson-Thompson, Sneaky Squirrel and Palindrome also being extended and infilled as part of the same campaign.

Opportunity – Gold in the Yilgarn

  • Gold is a globally strategic commodity, with Australian production concentrated in the prolific Yilgarn Craton of Western Australia – the same geological terrane hosting the Mons Greenstone Belt.
  • Orogenic gold systems along greenstone-granite contacts are among the most productive deposit styles in the Yilgarn, comparable to those hosting world-class deposits across the Eastern Goldfields.
  • The short history of focused gold exploration within the Mons Greenstone Belt means the belt remains largely untested for this deposit style – an unusual opportunity in a highly prospective region.
  • The Corporate James Trend’s 16-kilometre strike provides multiple targets for follow-up, with the 85 kilometres of untested greenstone contact to the north representing a significant exploration upside.

Key Highlights

  • Coherent, multi-element gold-in-soil anomaly confirmed along a ~16km corridor at the eastern granite–greenstone contact
  • Corporate James Prospect: anomalous gold-in-soil envelope of 720m (N-S) × 350m (E-W)
  • Pathfinder suite – Ag, As, Bi, Mo, Sb, Te, W – consistent with both orogenic and intrusion-hosted gold styles
  • Results situated within residual regolith (CSIRO Landscape+), validating the geochemical signal
  • Drill programme design commenced; drilling planned for the coming quarter
  • Broader CJ Trend extends over ~16km of strike, remaining open at both ends.

Future Plans

  • Nimy’s geological and geophysical database is being integrated with the new soil sampling data to refine drill target definition along the Corporate James Trend.
  • An initial drill programme is being designed to test the source of the gold anomalies at the Corporate James Prospect – the highest-priority target within the trend.
  • Extensional soil sampling along strike from Corporate James has been prioritised, with additional targets generated from this work scheduled for further sampling.
  • The 85 kilometres of untested greenstone contact extending beyond the current trend represents a significant pipeline of future exploration work as the programme matures.

Given the short history of gold exploration in the area now known as the Mons Greenstone Belt, there are several reasons to be very encouraged by what we have seen. The coherence and strength of the gold in soil anomaly along with the pathfinder elements support the potential for gold mineralisation. We are moving forward in designing an initial drill program to test for the source of the gold anomalies.

With targeted gold exploration now advancing alongside metallurgical test work and economic studies at the Block 3 gallium project, as well as ongoing geophysical work to identify the source of the Masson copper-nickel-PGE and Sneaky Squirrel copper-zinc-gold mineralisation, we expect to be very active on the ground in the second half of 2026.
