Great Southern Mining Launches Extensive Drilling Campaign to Boost Gold Resources in Western Australia

Mon Ami Gold Project Drilling Targets Resource Expansion

Located 12km southeast of Laverton, Western Australia, the Mon Ami Gold Project is central to Great Southern Mining’s current exploration initiatives. The project holds a JORC Mineral Resource of 1.56Mt at 1.11 g/t Au, totaling 55.5Koz. The ongoing RC drilling program aims to test depth extensions and northern mineralisation zones. Sixteen holes totaling 3,101 meters were completed in early July, with assay results anticipated by the end of the month.

Mon Ami’s proximity to multiple gold processing facilities, accessible via trucking, enhances its development potential. Situated on the Barnicoat Shear—a geological structure known for hosting significant gold deposits—the project is exploring monetisation options including small-scale mining ventures, which could expedite production if exploration results prove positive.

Golden Boulder Discovery Set for Extensive Drilling

Great Southern Mining is preparing to initiate a substantial drilling program at the Golden Boulder discovery within the Duketon Gold Project. This campaign aims to confirm mineralisation continuity along the Main Line trend, extend mineralisation at depth, and infill drill lines to improve resource definition. Historically, Golden Boulder has produced 1,761 ounces of gold and lies on a structural trend hosting several notable gold deposits.

The planned 15,000-meter RC drilling program will focus on expanding known mineralisation and exploring new targets. Golden Boulder forms part of a wider exploration strategy within the Duketon Greenstone Belt, where Great Southern Mining holds significant exploration licenses. These efforts could lead to new gold resource discoveries, bolstering the company’s asset base and appeal to investors.

Amy Clarke Drilling to Commence Post-Golden Boulder

Following Golden Boulder’s drilling, Great Southern Mining will focus on the Amy Clarke target, also within the Duketon Gold Project. Previous exploration identified mineralisation over a 4.7km strike, which remains open both along strike and at depth. Upcoming drilling will aim to expand this emerging discovery and better define its potential.

Located in a prolific gold-producing region, the Duketon Gold Project shares the greenstone belt with Regis Resources, which has identified over 10 million ounces of gold resources. Great Southern Mining’s exploration activities here are driven by the potential to uncover significant gold deposits, supporting the company’s growth strategy and long-term value creation.

Corporate Updates and Financial Strength

Alongside exploration, Great Southern Mining has bolstered its financial position through a successful equity placement, raising A$4.6 million. Directors and management contributed A$0.4 million following shareholder approval in May 2026. As of June’s end, the company held a cash balance of A$4.8 million, providing financial flexibility to advance exploration and development initiatives.

This capital raise reflects leadership’s confidence in the company’s exploration strategy and growth outlook. Funds will support drilling programs and potentially accelerate project development, aligning with the objective of becoming a key player in Australia’s gold mining sector.

Upcoming Drilling at Mt Dillon IP Target in Queensland

Beyond Western Australia, Great Southern Mining plans to commence drilling at the Mt Dillon IP target in Queensland. Identified via induced polarisation surveys by joint venture partner G Ex Resources, a subsidiary of Gold Fields Ltd, in 2024, drilling is scheduled to start in July 2026. This marks a significant step in the company’s Queensland exploration efforts.

The Mt Dillon target offers promising potential for new mineral discoveries. Collaboration with Gold Fields Ltd brings additional expertise and resources, enhancing project prospects. Investors will closely watch drilling progress and any impactful discoveries that could influence the company’s valuation and growth trajectory.

Importance of Mon Ami and Duketon Projects

The Mon Ami and Duketon projects are pivotal to Great Southern Mining’s exploration strategy, presenting strong potential for resource growth and development. Mon Ami’s existing JORC Mineral Resource and proximity to processing facilities position it well for future production. The Duketon project’s extensive landholding in a highly prospective region offers multiple exploration targets and the chance for significant resource additions.

These projects form part of the company’s broader vision to build a robust portfolio of Australian gold assets. Successful exploration and resource definition at Mon Ami and Duketon could enhance the company’s competitive edge and attract investors seeking exposure to the gold sector.

Exploration and Development Risks

While Great Southern Mining’s exploration presents notable opportunities, inherent risks remain. Drilling success depends on geological factors and converting targets into viable resources. The company also faces operational and financial risks, including potential cost overruns and delays.

Market dynamics such as gold price fluctuations and investor sentiment may impact capital raising and project advancement. Management is focused on risk mitigation through strategic planning, prudent financial management, and leveraging partnerships to improve exploration success.

Investor Outlook and Future Milestones

Investors will closely monitor results from ongoing and upcoming drilling at Mon Ami, Duketon, and Mt Dillon. Pending assay results from Mon Ami and the start of drilling at Golden Boulder and Amy Clarke represent key milestones that could affect market valuation and investor sentiment.

Great Southern Mining’s strategic emphasis on expanding its gold resource base and progressing projects toward production aligns with its growth objectives. As exploration results emerge, investors will gain clearer insights into the value of the company’s assets and its future prospects within Australia’s gold mining industry.
