Great Southern Mining

What Great Southern Mining does

Great Southern Mining Limited (ASX:GSN), formerly Forte Consolidated Limited and incorporated in Australia in January 2011, is a Perth-based, ASX-listed mineral exploration company focused on gold and base metals in proven Australian greenstone belts. The company operates a portfolio of four 100%-owned projects in Western Australia and Queensland: the Duketon Gold Project (including the Golden Boulder, Amy Clarke and Southern Star prospects along shear zones shared with Regis Resources), the Mon Ami Gold Project (a defined JORC 2012 Mineral Resource of 1.56 Mt at 1.11 g/t Au for 55,500 ounces located ~14 km from the Granny Smith Mill), the East Laverton Nickel Project (405 km² prospective for intrusive-style nickel-copper-PGE and Kambalda-style komatiitic nickel targets including the 110 km² Diorite Hill layered magmatic intrusion), and the Edinburgh Park Project in North Queensland (~1,750 km²), the last of which is subject to a joint venture with Gold Fields allowing Gold Fields to earn 75% through A$15M of exploration expenditure.

Exploration activity uses a standard but multi-modal toolkit — reverse circulation, diamond core and aircore drilling; induced polarization, electromagnetic and magnetic geophysical surveys; and surface geochemistry including hyperspectral analysis — with current programs emphasising deep diamond drilling at Golden Boulder and Diorite Hill to test structural and intrusive-hosted mineralisation below the depth envelope historically drilled (~40 m average vs. 150 m+ required). The business is pre-revenue: income is generated through the creation and monetisation of exploration assets rather than the sale of products or services, with capital sourced from ASX equity raisings, JV earn-in contributions (Gold Fields on Edinburgh Park), government Exploration Incentive Scheme co-funded drilling grants, and the divestiture of non-core mining leases. Customer relationships are framed as joint venture partnerships with major miners and asset-level transactions rather than recurring commercial contracts.

The headcount is small (1–10 employees), the operating geographies are Western Australia and Queensland, and the senior team — including Executive Chairman John Terpu (Mt Carlton discoverer via Conquest Mining) and Exploration Manager Matthew McCarthy (involved in the +8Moz Tropicana discovery for AngloGold Ashanti) — provides a proven discovery track record that is central to how the company differentiates itself in a capital-intensive, JV-driven junior exploration model.

Core offering

Great Southern Mining is a mineral exploration company that conducts drilling programs and geophysical surveys to identify and delineate gold and base metals deposits across its portfolio of exploration projects in Western Australia and Queensland. The company currently monetises its assets via joint venture earn-in arrangements with major miners (e.g., Gold Fields at Edinburgh Park), equity capital raises on the ASX, and government co-funded drilling grants, targeting future revenue through mine development or asset divestment.

Product overview

Great Southern Mining Limited is an Australian ASX-listed mineral exploration company offering a portfolio of four distinct exploration projects. The company's Western Australian assets include the Duketon Gold Project (gold exploration with Golden Boulder, Amy Clarke, and Southern Star prospects), the Mon Ami Gold Project (an advanced gold project with an existing 55,500oz resource), and the East Laverton Nickel Project (nickel-copper-PGE exploration). In Queensland, the Edinburgh Park Project covers copper-gold porphyry and epithermal targets under a joint venture with Gold Fields. The company focuses on systematic exploration using drilling programs (RC, diamond, and aircore) to define mineral resources, primarily targeting gold and base metals deposits in established Australian mining regions.

Products and services

• Duketon Gold Project Gold exploration project covering approximately 269 km² in the Duketon Greenstone Belt of Western Australia, including the Golden Boulder, Amy Clarke, and Southern Star prospects along major shear zones shared with gold producer Regis Resources. The project targets multi-million-ounce discovery potential along the same structural corridors that host major adjacent deposits.
• Mon Ami Gold Project Gold project located 14 km east of the Granny Smith Mill in Laverton, Western Australia, with an existing JORC 2012 Mineral Resource of 1.56 Mt at 1.11 g/t Au for 55,500 ounces of gold. The project offers proximity-based development optionality leveraging existing processing infrastructure.
• East Laverton Nickel Project Nickel exploration project comprising four granted exploration licences covering 405 km², located approximately 35 km from Laverton, Western Australia. It is prospective for intrusive-style nickel-copper-PGE mineralisation at the Diorite Hill layered magmatic intrusion and for Kambalda-style komatiitic nickel mineralisation, with additional orogenic gold potential.
• Edinburgh Park Project Copper-gold exploration project in northern Queensland (~1,560 km²) prospective for porphyry-hosted gold-copper mineralisation, high and low sulphidation epithermal gold-silver systems, and intrusion-related gold. Subject to a joint venture with Gold Fields where Gold Fields can earn a 75% interest by spending A$15 million on exploration, providing non-dilutive funding and major-miner technical validation.
