Golden Horse Minerals Limited Reports Drilling Results and Exploration Updates At Southern Cross Gold Project
Golden Horse Minerals Limited has reported additional drilling assays from ongoing Reverse Circulation (RC) and Diamond Drilling (DD) activities at Hopes Hill, located approximately 7km north of the town of Southern Cross in Western Australia. RC and Diamond Drilling from Hopes Hill has returned numerous wide, high-grade intercepts from all drill target zones along a +3km mineralised corridor. Results include Hopes Hill Main: 26HHRC148: 8.0m @ 9.1 g/t Au from 124m including 4.0m @ 17.4 g/t Au from 128m; 26HHDD018: 4.4m @ 12.4 g/t Au from 234.5m; 26HHRCD078: 8.8m @ 4.8 g/t Au from 356.2m, including 4.8m @ 7.6 g/t Au from 356.2m, and 5.0m @ 2.1 g/t Au from 315.0m; GHHHRCD0126: 5.0m @ 5.1 g/t Au from 118.0m, and 5.0m @ 1.9 g/t Au from 203.0m, and 1.0m @ 8.5 g/t Au from 230.0m, and 2.5m @ 6.8 g/t Au from 358.0m; 26HHDD017: 6.5m @ 4.1 g/t Au from 202.2m, and 9.0m @ 2.5 g/t Au from 262.0m; 26HHDD020: 9.1m @ 1.9 g/t Au from 228.9m, and 4.2m @ 4.1 g/t Au from 190.7m; 26HHRC150: 4.0m @ 4.2 g/t Au from 211m; 26HHRC154R: 5.0m @ 3.4 g/t Au from 222m. Extensional (Hopes Hill North, Hopes Hill South): 26HHRC183: 9.0m @ 2.4 g/t Au from 184m; GHHSRC009: 4.0m @ 3.8 g/t Au from 112m; 26HHRC031: 9.0m @ 1.4 g/t Au from 296m; 26HHRCD067: 4.5m @ 1.8 g/t Au from 302.5m. Drilling to date at Hopes Hill by the Company since 2025 will soon exceed 100km of RC and Diamond metres, with current and future results to inform a future inaugural Mineral Resource Estimate. Two Mining Lease applications at Hopes Hill North have been submitted to the WA Department of Mines, Petroleum and Exploration, with this area under application being earmarked for conceptual minor infrastructure to support the Company’s existing granted mining leases at Hopes Hill. Assay results have been returned for a number of holes from Hopes Hill North, Main and South. Following encouraging results from holes intercepting footwall mineralisation underneath the historic 1.3km long Hopes Hill mine, several new holes were drilled to target and test the footwall lode in various locations along the length of the pit. Results continue to provide valuable insights on lode geometry, reflecting the increasing knowledge which is manifesting as predicting and intercepting high-grade lode mineralisation. Hole 26HHDD018 (4.4m @ 12.4 g/t Au from 234.5m) returned a high-grade hit similar to previously reported diamond holes 26HHDD001 (4.0m @ 4.6 g/t Au from 297m) and 26HHDD010 (16.0m @ 6.8 g/t Au from 115.0m), in addition to delivering ‘proof of concept’ of the presence of multiple lodes as demonstrated by results in GHHHRCD0126, 26HHDD017 and 26HHDD020, each of which returned several downhole mineralised intercepts. Deep, high-grade extensions continue to be intersected in both target areas, strongly supporting the rationale of a large mineralised system at depth along the +3km strike length at the broader Hopes Hill project. Results have been received from a number of holes at Hopes Hill Main, with key results returned from the northern end of the historic pit in diamond holes 26HHDD020 and 26HHRCD078 along with the following intercepts returned from holes alongside the historic ~1.3km long pit: 26HHDD018: 4.4m @ 12.4 g/t Au from 234.5m; GHHHRCD0126: 5.0m @ 5.1 g/t Au from 118.0m, and 5.0m @ 1.9 g/t Au from 203m, and 1.0m @ 8.5 g/t Au from 230m, and 2.5m @ 6.8 g/t Au from 358.0m; 26HHDD017: 6.5m @ 4.1 g/t Au from 202.2m, and 9.0m @ 2.5 g/t Au from 262.0m; 26HHDD020: 9.1m @ 1.9 g/t Au from 228.9m, and 4.2m @ 4.1 g/t Au from 190.7m. Additional deep RC holes were designed and drilled as follow-up holes surrounding 26HHRC024, which returned 12m @ 7.0 g/t Au from 278m proving mineralisation at depth at Hopes Hill North. In hole 26HHRC183, the result of 9.0m @ 2.4 g/t Au from 184m has increased the strike extent of this high-grade zone by a further ~130m to the North, with future diamond drilling planned to further understand depth extensions, structural data collation and mineralogical abundance associated with high-grade mineralisation shown in RC drilling to date. Immediately north of the existing Hopes Hill pit, diamond drill hole 26HHDD017 (6.5m @ 4.1 g/t Au from 202.2m) has effectively “twinned” mineralisation proximal to hole GHHHRC0085 (3m @ 0.6 g/t Au from 215m), with an additional deeper mineralised intercept returned of 9m @ 2.49 g/t Au from 262m, which includes a higher-grade component of 6m @ 3.43 g/t Au from 262m. The intent behind diamond hole 26HHDD017 was to delineate an inferred north-east trending fault which is interpreted to dislocate the hanging wall schist contact, reflecting the varying mineralisation styles evidenced in 26HHDD017 and GHHRC0085. Mineralisation on the footwall contact (9m @ 2.49 g/t Au from 262m) of the intersected fault confirmed the theory, resulting in a greater understanding of the system at depth and thus requiring further follow up extensional drilling to extend footwall mineralisation in this immediate area. Drilling underneath the southern end of the Hopes Hill pit has returned several significant intercepts from 26HHRC148 and 26HHRC150, including the following results: 26HHRC148: 8m @ 9.15 g/t Au from 124m (4m composite sample), including 4m @ 17.44 g/t Au from 128m, and 5m @ 1.37 g/t Au from 245m; 26HHRC150: 6m @ 2.91 g/t Au from 210m, and 2m @ 1.53 g/t Au from 130m. These holes are located in the immediate vicinity (within 200m) of the following holes, which were recently reported by the Company on 18 June 2026: 26HHRC147: 12m @ 7.29 g/t Au from 116m, including 4m @ 20.2 g/t Au from 124m; 26HHRC146: 12m @ 3.08 g/t Au from 132m including 4m @ 7.57 g/t Au from 140m. These intercepts signify high-grade plunging shoot geometries, with the three 4m high-grade intercepts from 26HHRC146, 26HHRC147 and 26HHRC148 from similar downhole depths, and all within broader mineralised intercepts to 12m widths requiring infill drilling within this area to further understand lode geometries including planned future diamond drilling for structural and geotechnical purposes. DD drilling is ongoing across the Hopes Hill region, along with ongoing core logging and assaying activities, and results expected to be released progressively. An independent resource geologist has been engaged to develop Golden Horse’s inaugural Mineral Resource Estimate for Hopes Hill, with activities due for completion later in calendar year 2026 in parallel with ongoing drilling and assaying activities. RC drilling activities have concluded for First Half calendar year 2026 with programs completed south of Southern Cross at the Greenmount, Bells and Lynette prospects targeting varying styles of gold mineralisation. Early-stage exploration will recommence from July 2026 with field mapping, sampling and auger drilling activities proposed ahead of the recommencement of regional RC drilling later in calendar year 2026.
