Great Southern Mining Limited
Great Southern Mining is a WA-focused gold explorer with two distinct project areas: the 100%-owned Duketon Gold Project (Laverton region, Duketon Greenstone Belt, adjacent to Regis Resources' 8Moz+ endowed belt), where the Golden Boulder discovery -- per the company's own PR, '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; deep diamond drilling began March 2026 (co-funded by a WA Government EIS grant) working towards a maiden JORC Mineral Resource -- no resource has been declared yet at Duketon/Golden Boulder. A separate deep EIS-funded hole at the Diorite Hill target (East Laverton Project) is testing reef-style PGE-Ni-Cu mineralisation. Cash balance 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. The company also holds a separate Mon Ami gold project (12km south of Laverton, a real 55,500oz JORC resource -- 1.56Mt at 1.11 g/t Au -- on a granted mining lease, being drilled for extensions as potential satellite mill feed), deliberately not blended into this pass's Duketon-flagship figures.

Lifecycle Milestones
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 the underlying research identifies — whether a major already holds a JV, earn-in, or 5–19.9% strategic stake — isn't tracked yet and is absent from this score.

[Description-field-gaps audit batch 3] ouncesFound correctly null: the description's "Regis Resources' 8Moz+ endowed belt" is Regis Resources Limited's (ASX:RRL) OWN Duketon Gold Operations (Moolart Well/Garden Well/Rosemont, same Duketon Greenstone Belt, Laverton region, WA), cited only as belt-adjacency context for GSN's own Duketon Gold Project. Not GSN's resource. No resource has been declared yet at GSN's own Duketon/Golden Boulder discovery (maiden JORC Mineral Resource still pending); the separate Mon Ami project's real 55,500oz JORC resource is deliberately not blended into this description's Duketon-flagship figures, per this row's own text.
