Exploration activity across the Gawler Craton is accelerating, driven by a convergence of high-grade gold discovery and aggressive drill programs now underway. Marmota Limited’s (ASX: MEU) maiden drilling at the Greenewood gold discovery (Figure 1) has delivered some of the most spectacular near-surface gold results recorded in the region since the Challenger Mine’s breakthrough in 1995, defining almost one kilometre of continuous mineralisation.

OD6 Metals Ltd (ASX: OD6) is shaping into one of Australia’s most strategically positioned critical-minerals developers, underpinned by two assets: Splinter Rock Rare Earths Project & Gulf Creek Copper-Zinc Project. Both projects benefit from Tier-1 jurisdictions, with Splinter Rock tied directly into the Esperance Port corridor and Gulf Creek positioned within NSW’s Renewable Energy Zones.

Impact Minerals Limited (ASX: IPT) has resumed exploration at its 100%-owned Broken Hill Project (NSW), citing stronger metal prices, new in-house copper concepts from the BHP Xplor program, and renewed third-party activity in the district (Figure 1). The Company has begun a progressive review of past work and presents context and results from Platinum Springs as the first step.

As the global energy transition accelerates, demand for base metals like copper (Cu), lead (Pb), zinc (Zn), and nickel (Ni) is booming. Yet, exploration success rates for major discoveries are shrinking worldwide. In Australia—home to an array of world-class resources—the biggest challenge isn’t finding the right rocks, it’s working out where to start looking beneath the post-mineralisation cover that hides up to 80% of the continent’s prospective geology.

Pivotal Metals Limited (ASX: PVT) has released new Fixed-Loop Time Domain EM (FLTEM) results from the Midrim–Alotta area of the Belleterre-Angliers Greenstone Belt (BAGB) Projects in Abitibi, Québec, Canada, ~85 km south of Rouyn-Noranda (Figure 1). The work defines a substantial, untested conductive plate directly beneath the shallow, high-grade Alotta sulphide body, and indicates prior drilling was sub-optimal; a new NE-oriented drill strategy is now planned to test depth

In March 2025, Cyprium Metals Ltd (ASX: CYM) presented a clear vision to the market—a strategy built on speed, simplicity, and a low-capex restart of the Nifty Copper Complex (Figure 1). The March investor presentation positioned Nifty as a rare brownfield asset with infrastructure already in place, permits largely secured, and over 720kt of copper historically produced.

Pivotal Metals Limited (ASX: PVT) has revealed encouraging results from its latest high-resolution magnetic survey over the Lorraine property, a critical part of its 100%-owned Belleterre-Angliers Greenstone Belt (BAGB) project in Quebec, Canada (Figure 1). The program has significantly enhanced the geological understanding of the Lorraine area, unveiling new structural features and target zones for high-grade copper, nickel, platinum group metals (PGMs), and gold exploration

Mount Hope Mining Limited (ASX: MHM) is a newly listed exploration company focused on copper and gold in the Southern Cobar Basin of New South Wales. With a 175km² strategic landholding and a well-connected location in an established mining region, the company is positioning itself within a district known for its polymetallic endowment and historic production.

When I reviewed LinQ Minerals Limited’s IPO Replacement Prospectus (27 May 2025) and accompanying investor presentation, it was clear this is not your standard greenfields hopeful. LinQ offers something much more compelling: a genuine brownfields gold-copper project with real tonnage, credible grade, deep geological understanding, and—importantly—a team that’s been here before.
