Golden Horse Minerals has hit its deepest gold mineralisation to date at Hopes Hill, with drilling revealing a thickening lode system over 378 metres downhole. Alongside strong near-surface intercepts, the company is advancing a major 2026 drilling campaign targeting a maiden resource estimate.
- Deepest mineralised intercept: 24.18m at 2.2 g/t Au from 378.8m
- High-grade near-surface hits including 4m at 20.2 g/t Au
- Over 50,000m drilled safely in 2026, aiming for 125,000m total
- Multiple rigs active targeting lode extensions and regional prospects
- Maiden Mineral Resource Estimate planned for second half of 2026
Deep Mineralisation Uncovered Beneath Historic Pit
Golden Horse Minerals (ASX:GHM) has unveiled its deepest and potentially most significant gold intercept at the Hopes Hill deposit within its Southern Cross Gold Project. Hole 26HHRCD077 returned 24.18 metres at 2.2 grams per tonne (g/t) gold starting from 378.82 metres downhole, nested within a broader 40.2-metre mineralised zone averaging 1.5 g/t Au. This intercept lies some 350 metres below the previously mined Hopes Hill pit, which historically reached only about 50 metres depth due to access constraints.
The company’s Managing Director, Nicholas Anderson, described the result as opening a “new area” for exploration, highlighting the thickening of the lode system at depth and the potential to extend mineralisation well beyond the historic mine footprint. This deep discovery could reshape the scale and economics of the project if further drilling confirms continuity and grade.
Strong Shallow Gold Zones Bolster Resource Potential
Drilling is ongoing with two diamond and two RC rigs operating, targeting lode extensions at Hopes Hill North, Main, and South zones. The program has already surpassed 50,000 metres of combined drilling in 2026, on track toward a targeted 125,000 metres for the calendar year. The company is also conducting regional scout drilling at prospects including Greenmount, Lynette, and Bells, aiming to expand its footprint across the Southern Cross Greenstone Belt.
Technical Insights and Geological Context
The deep mineralisation is associated with strong silica and biotite alteration, quartz veining, and sulphide assemblages typical of orogenic gold systems. The geological model suggests the lode system thickens at depth and contains high-grade plunging shoots, as evidenced by the 4 metres at 20.2 g/t Au intercept. Planned diamond drilling will focus on structural controls and down-plunge extensions to better define the system’s geometry and grade distribution.
Previous drilling and geological interpretation have extended the known mineralised strike length at Hopes Hill beyond 3 kilometres, with multiple zones showing consistent gold mineralisation. The company’s approach integrates diamond tails on RC pre-collars to improve core recovery and orientation, supporting robust geological modelling and future resource estimation.
Assay Delays and Next Steps Toward Resource Estimation
Golden Horse cautions that assay results are currently subject to industry-wide laboratory delays of three to four weeks, slowing the pace of data release. However, the company remains committed to maintaining drilling momentum and expects to deliver an inaugural Mineral Resource Estimate in the second half of 2026. This estimate will be a critical milestone, synthesising the extensive drilling data into a formal resource model to underpin development decisions.
Beyond Hopes Hill, active regional exploration programs continue, including rock chip and soil sampling and new drill campaigns at several prospects. These efforts aim to leverage the extensive tenure position Golden Horse controls in the prolific Southern Cross region.
Bottom Line?
Golden Horse’s deep and near-surface gold hits at Hopes Hill reinforce its potential to evolve into a sizeable resource, but assay delays and ongoing drilling mean investors should watch closely for the maiden resource estimate later this year.
Questions in the middle?
- Will further deep drilling confirm the thickening lode system and improve grade continuity at depth?
- How will the maiden Mineral Resource Estimate shape development plans and project valuation?
- Can regional scout programs identify new discoveries to complement Hopes Hill’s growing footprint?
