Overview of GSN's successful drilling campaign at Duketon Gold Project

Great Southern Mining Limited (ASX:GSN) has completed a targeted 15-hole (1,946 m) RC drilling program at its 100% owned Duketon Gold Project in Western Australia. The drilling primarily focused on the Golden Boulder prospect, where shallow high-grade gold was intercepted in step-out drilling, extending the higher-grade mineralised zone by 85 m to 370 m total. GSN also reported highly encouraging results from its first drilling campaign at the Boundary prospect, with plans to embark upon a multi-phase drill-out program.

Executive commentary on the drilling results

Golden Boulder continues to return shallow high-grade intercepts. Following several low-metreage targeted drilling programs, we believe this prospect now warrants a significant drill-out to test the 3.7 km prospective trend. We are also highly encouraged by the early success at the Boundary prospect. We believe this area holds significant potential for gold discoveries given its location along a major structural zone, which lays host to Regis Resources +5 Moz Garden Well deposit located 20 km to the north.

Summary of the drilling results and future plans

The recent drilling campaign at Duketon Gold Project has delivered promising results, with shallow high-grade gold intercepts at the Golden Boulder prospect and encouraging outcomes at the Boundary prospect. GSN plans to embark upon a multi-phase drill-out program to further explore the scale and prospectivity of targets defined at the Duketon Gold Project. The Company's short to medium-term strategy is to drill out key targets with the objective of delineating economic gold resources. GSN remains confident that exploration to date supports the Company's belief that its tenure could host the next major deposit in the region.
