Early-Stage Drilling Leaves Key Questions on Grade Continuity at West Tanami

Exploration Progress at West Tanami

Hamelin Gold Limited (ASX, HMG) has reported encouraging results from its ongoing exploration programs at the West Tanami Project in Western Australia’s Tanami Province. The company’s recent aircore and reverse circulation (RC) drilling campaigns have successfully extended zones of shallow gold mineralisation at two key prospects, Fremlins South and Jazz.

At Fremlins South, located approximately 14 kilometres south of the Coyote Gold Mine, aircore drilling has expanded the footprint of gold mineralisation with assays confirming a strike length exceeding 400 metres where gold grades surpass 1 gram per tonne. Notable intercepts include 6 metres at 1.34 g/t gold from 26 metres depth and 6 metres at 1.01 g/t from 40 metres. These results reinforce the presence of a sigmoidal dilational zone with potential for higher-grade shoots within the broader mineralised corridor.

Jazz Prospect Reveals Large Mineralised System

Meanwhile, at the Jazz prospect situated at the western end of the Sultan Gold Corridor, RC drilling has delineated broad zones of gold anomalism over a 500-metre strike length. The mineralisation is associated with the contact zones of the Jazz Granitoid and exhibits characteristics of a large hydrothermal system. Although grades are generally low to moderate, the system remains open to the south, west, and at depth, suggesting significant exploration upside.

Hamelin’s Managing Director, Peter Bewick, highlighted the significance of these findings, noting that the expanded shallow mineralisation at Fremlins South and the broad gold anomalism at Jazz underscore the potential for discovering higher-grade zones. He confirmed that follow-up drilling programs are planned for early 2026, timed to commence after the northern wet season, aiming to infill and extend the known mineralised zones and to refine geological models for targeting deeper drilling.

Strategic Positioning in a Proven Gold Province

The West Tanami Project is strategically located in a highly prospective gold province known for hosting multi-million ounce orogenic gold deposits, including Newmont’s Tier 1 operations nearby. Hamelin’s exploration approach combines modern geochemical techniques, such as the CSIRO-developed Ultrafine® analytical technology, with systematic drilling to unlock covered and underexplored terrains.

With strong backing from major shareholders including Gold Fields Limited and Vault Minerals Limited, Hamelin is well positioned to advance its exploration pipeline. The company’s methodical step-out and infill drilling programs aim to build a robust resource base that could underpin future development opportunities.

Next Steps and Market Implications

As Hamelin prepares for its 2026 drilling campaigns, investors will be watching closely for assay results that could confirm the continuity and grade of the mineralisation. The potential to define higher-grade shoots within these large mineralised systems could materially enhance the project’s value proposition. However, it remains early-stage exploration, and the true widths and economic viability of the mineralisation require further drilling and evaluation.
