Key Highlights

Hopes Hill North delivered Golden Horse's best-ever intercept: 48m at 6.3g/t Au from 44m including 4m at 73.3g/t Au from 88m in hole 26HHRC179, with visible gold confirmed by fire assay to extinction at 46.5–108.0g/t Au
Deep diamond drilling at Hopes Hill Main intersected 16.6m at 3.4g/t Au from 392.4m, including 5.0m at 9.9g/t Au from 399.0m, extending the high-grade system at depth
First-pass RC drilling at Greenmount returned gold mineralisation in all nine holes, highlighted by 8m at 16.3g/t Au from 209m including 3m at 37.6g/t Au from 214m in 26GMRC006
Sampling at the Withers prospect returned numerous results above 1.0g/t Au including a maximum grab sample of 15.08g/t Au, adding another regional target to Golden Horse's Southern Cross pipeline

Golden Horse Minerals Limited (ASX:GHM) emerged from the September 2026 quarter with a drill result that materially resets expectations for the Hopes Hill gold system. Hole 26HHRC179, drilled at Hopes Hill North, returned a 48-metre intersection grading 6.3 grams per tonne gold from 44 metres — including a 4-metre zone at 73.3g/t gold from 88 metres. The result stands as the company's highest-grade intercept to date and was accompanied by visible gold that fire assay to extinction confirmed at grades ranging from 46.5g/t to 108.0g/t gold.

The Hopes Hill North result is significant not just for its grade but for the width and continuity of the broader mineralised interval. A 48-metre intersection at over 6g/t gold is well above the threshold typically associated with economic open-pit potential in the Southern Cross region of Western Australia, and the near-surface position of the zone, beginning at just 44 metres depth, opens the possibility of near-surface Mining scenarios as the project matures.

Multi-Rig Campaign Drives Systematic Definition

The September quarter saw Golden Horse run a multi-rig program across the three components of Hopes Hill — Main, North and South — alongside the regional Greenmount prospect. At Hopes Hill Main, deep diamond drilling continued to probe the system below the historic open pit, returning 16.6m at 3.4g/t gold from 392.4 metres in hole 26HHDD031, including 5.0m at 9.9g/t gold. At Hopes Hill South, hole 26HHRC162 extended mineralisation down plunge, returning 21m at 1.5g/t gold from 215 metres. Refined 1-metre split assays also upgraded a previous result, with 26HHRC147 recalculated at 10m at 11.3g/t gold from 116 metres, including 2m at 52.3g/t gold.

The emerging picture across Hopes Hill is of a mineralised system with multiple high-grade shoots distributed across a plunge-coherent structure, extending from near-surface to at least 392 metres vertical depth. The distribution of results across the three sub-areas suggests the system is not yet closed at depth or along strike.

Greenmount Emerges as a Second Discovery

First-pass RC drilling at Greenmount, a regional target within Golden Horse's Southern Cross tenure, produced gold mineralisation in all nine holes tested — a result that sets Greenmount apart as a genuine second discovery rather than a speculative anomaly. The best result, 26GMRC006, intersected 8m at 16.3g/t gold from 209 metres including 3m at 37.6g/t gold. Other standout results included 26GMRC004 with 8m at 8.6g/t gold from 218 metres and 26GMRC005 with 12m at 5.2g/t gold from 139 metres.

The grades and widths at Greenmount are notable for a first-pass drill campaign and suggest a structurally hosted high-grade system consistent with the gold mineralisation style seen at Hopes Hill. The Company is building a target pipeline across its dominant Southern Cross landholding, with Withers — where grab sampling returned a maximum of 15.08g/t gold — identified as another prospect requiring follow-up drill testing.

Sector Context

The Southern Cross greenstone belt in Western Australia remains one of the most active exploration corridors on the ASX in 2026, supported by sustained gold prices and the geological precedent set by several producing mines and historical deposits in the region. Golden Horse's multi-rig approach at Hopes Hill, running RC and diamond drill campaigns simultaneously, reflects the operational pace typically associated with explorers that have identified a mineralised system warranting accelerated definition.

Risks

Despite the encouraging drill results, Hopes Hill remains at the exploration stage with no Mineral Resource Estimate published. The scale and economic parameters of the system are yet to be formally defined. Continued drilling will require ongoing capital, and any significant pullback in the gold price could affect the company's ability to maintain current exploration intensity. The depth extent of the high-grade zones introduces technical uncertainty around future extraction scenarios.

What to Watch Next

The most significant near-term catalyst is a Mineral Resource Estimate for Hopes Hill, which would translate the extensive drilling data into a quantifiable asset. Follow-up drilling at Greenmount, potentially expanding on the first-pass results, will also drive news flow. Ongoing deep diamond drilling at Hopes Hill Main and further work at Withers will continue to test the lateral and vertical limits of the Southern Cross Gold Project.
