Golden Horse Minerals Unveils New High-Grade Gold Zone at Southern Cross

New High-Grade Gold Discovery at Hopes Hill South

Golden Horse Minerals (ASX:GHM) has unearthed a compelling shallow high-grade gold zone approximately 200 metres south of the historic Hopes Hill pit in Western Australia's prolific Southern Cross region. The standout intercept, 7 metres at 13.0 grams per tonne (g/t) gold from 13 metres downhole including a blistering 2 metres at 44.3 g/t Au, validates the company's geological model of a large-scale shear-hosted mineralised system beneath small-scale historic workings.

This discovery not only extends the footprint of mineralisation but suggests stacked lodes within the hangingwall ultramafic unit, hinting at multiple splays that could add significant upside to the project’s resource base. The Hopes Hill mine historically produced 216,000 ounces of gold, and this new zone opens fresh avenues for exploration close to existing infrastructure.

Continued Growth at Hopes Hill Main and North

Beyond Hopes Hill South, ongoing reverse circulation (RC) and diamond drilling at Hopes Hill Main and North continues to delineate a robust mineralised system. Notable intercepts include 11 metres at 2.2 g/t Au from 144 metres and 6 metres at 3.6 g/t Au from 107 metres, reinforcing the presence of wide, high-grade zones both near surface and at depth.

These results build on Golden Horse’s aggressive 2026 drill campaign, which follows earlier encouraging findings such as visible gold intersections and deep high-grade extensions reported in March 2026. The company’s geological team is rapidly expanding the understanding of the system’s strike and plunge components, with further drilling planned to test continuity and depth extensions.

Golden Horse’s Managing Director Nicholas Anderson emphasised the strategic intent behind these efforts, noting the company’s readiness to advance despite market uncertainties, supported by a strong cash balance and a focus on operational efficiencies. This approach aligns with the company’s recent confirmation of free-milling gold at Hopes Hill, which supports promising metallurgical recoveries and underpins future processing plans.

Regional Exploration and Development Progress

Regional RC drilling at nearby prospects Hakes Find and Marionete has been completed, with over 5,000 metres drilled. Assay results remain pending due to laboratory backlogs but are expected to provide additional news flow and potential resource growth opportunities. Meanwhile, development studies at Hopes Hill Main are advancing, with flora, fauna, and hydrological reports now received, laying groundwork for potential project advancement.

Golden Horse continues to leverage its dominant 1,800 square kilometre tenure position within the Southern Cross Greenstone Belt, a well-endowed gold province with a history of significant production. The company’s exploration strategy, dubbed “The Year of the Horse,” is focused on methodical step-out drilling beyond known orebodies, aiming to unlock new zones and refine resource models.

As the company awaits further assay results and continues its drilling program, the evolving geological picture at Southern Cross presents a meaningful opportunity to expand the resource base and enhance project economics. Investors will be watching how these developments translate into updated resource estimates and feasibility outcomes over the coming quarters.
