Great Southern Mining is starting a large 20,000-metre drilling campaign across its Western Australia gold projects, according to multiple outlets. The program targets the Golden Boulder, Amy Clarke and Mon Ami discoveries. One report adds that the company is directing drilling at its Duketon and Mon Ami projects. The campaign is linked to a reinterpretation of earlier diamond drilling results, which is said to have improved estimates of how deep mineralisation could extend at the Golden Boulder discovery. The outlets describe the decision as a follow-on to these updated geological interpretations and position the drilling as a renewed push to test and expand the known targets. Details on timing, drilling locations beyond the named prospects, and any immediate results are not reported in the provided excerpts. Overall, the coverage is consistent in stating the company’s plan to drill 20,000 metres and the main targets: Golden Boulder, Amy Clarke and Mon Ami, with Duketon referenced as part of the focus area.
