Golden Boulder Drilling: Key Test for Great Southern Mining’s Growth Prospects

Drilling Resumes at a Key Western Australian Gold Prospect

Great Southern Mining Limited (ASX: GSN) has officially commenced reverse circulation (RC) drilling at its wholly owned Duketon Gold Project, located in the Eastern Goldfields of Western Australia. The initial focus is the Golden Boulder prospect, a site that has shown promising results in previous drilling campaigns conducted between 2021 and 2024.

The company’s renewed exploration push aims to build on earlier successes, which included significant gold intercepts such as 4 meters at 5.64 grams per tonne (g/t) gold and 3 meters at 4.80 g/t gold. These results underscore Golden Boulder’s potential as a high-grade target within the broader Duketon belt, a region known for its prolific gold mineralisation.

Strategic Focus on Infill and Step-Out Drilling

The current drilling program will incorporate both infill and step-out holes, designed to expand the known mineralised zones and improve the geological understanding of the area. Golden Boulder hosts three mineralised trends, Main line, East line, and Ogilvies, with previous drilling extending the Main line strike to 1.4 kilometres. However, the spacing of holes remains broad, leaving room for further delineation.

Great Southern Mining’s Managing Director, Matthew Keane, highlighted the strategic importance of Golden Boulder, noting its favourable structural setting where multiple gold-bearing structures converge. This structural complexity, combined with the prospect’s historical under-exploration since the 1990s, positions it as a compelling target for high-impact exploration.

Robust Funding Supports Exploration Ambitions

The company is well-capitalised to execute this drilling campaign, having completed a $2.4 million share placement in November 2024. Additionally, directors have committed a further A$152,000, subject to shareholder approval expected in March 2025. This financial backing provides the necessary runway for a thorough and cost-effective exploration program.

Golden Boulder’s location within the Duketon belt places it near several significant gold deposits, including Rosemont (over 2 million ounces), Baneygo (~380,000 ounces), and Ben Hur (~390,000 ounces). The prospect’s historical production, though limited and dating back to the early 20th century, recorded high-grade gold, reinforcing its potential.

Looking Ahead: Assay Results and Market Implications

As drilling progresses, the market will be keenly awaiting assay results that could validate the prospect’s potential to host economically viable gold mineralisation. Success here could not only enhance Great Southern Mining’s resource base but also elevate its profile within the competitive Western Australian gold exploration sector.

While the company remains cautious, acknowledging the inherent uncertainties of exploration, the combination of strong historical intercepts, a strategic location, and solid funding sets the stage for a potentially transformative phase in its development.
