Maiden RC Drilling Targets Deeper Gold Zones at Amy Clarke
Great Southern Mining (ASX:GSN) has kicked off an 18-hole reverse circulation (RC) drilling program totalling approximately 2,300 metres at its emerging Amy Clarke gold discovery, part of the 100% owned Duketon Gold Project in Western Australia’s Laverton District. This marks the first RC drilling at Amy Clarke, following earlier air core programs that identified significant gold mineralisation across a 4.7-kilometre strike length.
Prior drilling, predominantly shallow air core holes rarely exceeding 50 metres depth, returned encouraging intercepts including 17 metres at 1.4 grams per tonne (g/t) gold from 20 metres, highlighted by a 1-metre section grading 11.2 g/t Au, and 8 metres at 6.7 g/t Au from 33 metres. These results suggest the potential for higher-grade zones at depth, which the current RC program aims to delineate and better understand.
Strategic Location Near Established Processing Infrastructure
The Amy Clarke prospect lies roughly 12 kilometres south of Regis Resources’ Garden Well processing facility and 3.5 kilometres south of the Erlistoun gold mine, positioning it advantageously within the prolific Duketon Gold Belt. Unlike many deposits in the region, Amy Clarke had seen minimal historical exploration before Great Southern Mining’s tenure, and notably lacks historical shafts or workings, indicating a relatively fresh exploration frontier.
Broader Drilling Activity Continues Across Duketon and Queensland
While Amy Clarke drilling is underway, assay results are awaited for 16 holes (3,089 metres) recently completed at the Mon Ami Gold Project, located 12 kilometres south of Laverton, and for 38 holes (4,726 metres) drilled at the northern 1.1 kilometres of the Golden Boulder discovery within the Duketon Project. Further drilling of 68 holes is planned at Golden Boulder following completion of the Amy Clarke program.
Meanwhile, diamond drilling has commenced at the Mt Dillon target within the Edinburgh Park Project in northern Queensland. This program, managed and funded by G-Ex Resources; a wholly owned subsidiary of Gold Fields Ltd; is initially targeting up to 1,300 metres, focusing on a large chargeability and resistivity anomaly interpreted as a lithocap over an intrusive system.
Accelerated Exploration to Build on Recent Momentum
Great Southern Mining’s decision to start Amy Clarke drilling ahead of completing Golden Boulder assays reflects a push to accelerate results and maintain momentum across its portfolio. The company’s systematic approach combining surface geochemistry, structural mapping, geophysical surveys, and multiple drilling techniques aims to unlock new resource potential at these underexplored but strategically located prospects.
With assays pending and further drilling planned, the coming weeks will be critical for assessing the scale and grade continuity of mineralisation at Amy Clarke and its neighbours, potentially shaping the next phase of resource development in this historically prolific gold belt.
Bottom Line?
Amy Clarke’s maiden RC drilling could redefine Great Southern Mining’s resource potential in the Duketon belt, but assay results will be pivotal in confirming the discovery’s depth and grade extensions.
Questions in the middle?
- Will the RC drilling at Amy Clarke confirm higher-grade gold zones at depth beyond previous shallow air core results?
- How might pending assay results from Mon Ami and Golden Boulder influence the company’s near-term exploration priorities?
- What impact could the diamond drilling outcomes at Mt Dillon have on Great Southern Mining’s Queensland portfolio?
