Why It Matters

A confirmed discovery would give Cosmo a high‑grade gold asset and a foothold in the critical antimony market, driving valuation upside and supporting Australia’s strategic mineral supply goals.

Key Takeaways

  • Cosmo targets discoveries near known deposits, “fishing where the fish are.”
  • Kurnalpi project sits within km of 7 M oz Kurnalpi Bell mine.
  • Upcoming two‑stage drilling includes deep diamond hole funded by WA government.
  • Antimony demand rises due to fire‑retardant and defense applications.
  • NSW projects sit in under‑explored southern New England ore belt.

Summary

Cosmo Metals’ managing director Ian Pretorius outlined the company’s discovery‑driven strategy, emphasizing that it seeks mineralisation adjacent to known, high‑grade deposits – a philosophy he describes as “fishing where the fish are.” The focus is on two core jurisdictions: Western Australia’s Kurnalpi gold project, located just kilometres from the 7 million‑ounce Kurnalpi Bell mine and 13 km from Kalgoorlie’s mining hub, and a suite of New South Wales assets in the southern New England ore belt, targeting gold, copper and the increasingly strategic antimony.

In WA, Cosmo is preparing a two‑stage drilling campaign. Initial reverse‑circulation holes will test deeper extensions of surface signatures, while a state‑backed 400‑metre diamond drill will probe a northern prospect with structural parallels to the nearby Kurnalpi Bell deposit. Historical drill intersections at the Don El Barro target (18 m @ 5.5 g/t Au) underscore the potential for high‑grade mineralisation. In NSW, the company leverages government prospectivity studies that identified the Bingara and Nundle licences as high‑potential, especially for antimony, a metal gaining attention for fire‑retardant and defense uses.

Pretorius highlighted the “Invincible‑style” deposit model – a >1 Mt, high‑grade open‑pit ore body discovered at Gold Fields’ St Ives – as the template for the Kurnalpi target. He also noted that the Western Australian Exploration Incentive Scheme and similar NSW grants provide non‑dilutive capital, allowing Cosmo to advance costly deep drilling without immediate equity dilution.

If the upcoming drilling validates the deep targets, Cosmo could secure a multi‑million‑ounce gold discovery and position itself as a key supplier of antimony, aligning with Australia’s critical‑minerals strategy. Successful outcomes would enhance the company’s valuation, attract strategic partners, and potentially deliver near‑term monetisation pathways through infrastructure‑rich proximity to existing processing facilities.

In this interview, StockBox spoke to Ian Prentice, Managing Director of Cosmo Metals (ASX:CMO), about the company’s discovery-led exploration strategy, upcoming drilling at the Kanowna gold project in Western Australia, and the growing potential of its gold, copper and antimony assets in New South Wales.
Key points:
Discovery-first strategy: Cosmo is focused on exploring near known major deposits and historic mining districts.
Active drilling catalysts: Near-term drilling at Kanowna will test deeper gold targets, with government-backed diamond drilling adding further upside.
Exposure to critical minerals: Cosmo’s New South Wales portfolio gives it leverage not only to gold and copper, but also to rising interest in antimony.
