Great Southern Mining Limited
Great Southern Mining is a WA-focused gold explorer with two project areas. At the 100%-owned Duketon Gold Project (Laverton region, Duketon Greenstone Belt, next to Regis Resources' 8Moz+ endowed belt), the Golden Boulder discovery, which the company calls 'rapidly emerging as the flagship prospect', has been extended to a ~3.5km mineralised strike (over 50 historical workings; historical production of 1,761oz at 28.6 g/t Au from 1900-1955) via a 5,234m RC program, and deep diamond drilling began in March 2026 (co-funded by a WA Government EIS grant) working towards a maiden JORC Mineral Resource. A separate deep EIS-funded hole at the Diorite Hill target (East Laverton Project) is testing reef-style PGE-Ni-Cu mineralisation. The Mon Ami gold project (12km south of Laverton) carries a current JORC Mineral Resource of 1.56Mt at 1.11 g/t Au for 55,500oz on a granted mining lease and is being drilled for extensions as potential satellite mill feed. Cash was A$5.6 million at 31 Mar 2026, with a further A$4.6M placement completed since to fund an expanded ~20,000m regional drilling program.

Acquisition Susceptibility
A relative ranking of how closely this company matches the profile of juniors that have actually been acquired — not a probability, and not a reason to buy. Acquisitions are rare: only a few dozen significant deals happen a year across a universe of thousands of juniors, so even a high score here describes a long shot. The strongest signal in the research, a producer that already owns part of the company, is scored from its disclosed strategic shareholders. A producer that is a joint-venture or earn-in partner on the project, rather than a shareholder, isn't captured yet.
How this score is built
- Disclosed pending dealSub-score: Not scored
No pending acquisition or merger disclosed (checked)
Not scored: having no deal in flight isn't held against a company.
Weight 26.25% - Producer's strategic stakeSub-score: Not scored
No producer holds a disclosed stake on file (holder register researched) See holders
Not scored: most juniors that do get bought had no prior toehold, so a missing stake says little either way.

Reports, Presentations & Documents
Great Southern Mining explores for gold in Western Australia's Laverton region. At its 100%-owned Duketon Gold Project in the Duketon greenstone belt, the Golden Boulder discovery has been extended to about 3.5km of mineralised strike, with more than 50 historical workings, and deep diamond drilling that began in March 2026 is working toward a maiden JORC resource. Its Mon Ami gold project, on a granted mining lease 12km south of Laverton, carries an inferred JORC resource of 1.56 Mt at 1.11 g/t for 55,500 oz of gold, and drilling reported in August 2026 extended the main lode, including 16m at 3.37 g/t gold from 178m. The company had A$5.6 million in cash at 31 March 2026 and has since completed an A$4.6M placement to fund an expanded regional drilling program of about 20,000m.
