Golden Horse Minerals Limited
Golden Horse Minerals (renamed from Altan Rio Minerals Limited, July 2023) explores the Hopes Hill Project within its Southern Cross Gold Project tenure in Western Australia's Southern Cross Greenstone Belt, and separately owns the Sorrel Copper Project, a copper-only asset (no gold credit identified) in the Northern Territory's McArthur Basin. Sorrel -- the former Redbank and Wollogorang Copper Projects -- was acquired 100% from NT Minerals Limited (ASX:NTM) for $1.0M cash plus 4.63 million Golden Horse CDIs (valued at over $2.15M at completion, escrowed 12 months), completing September 2025 after a September 2024 option period in which Golden Horse spent $5.1M on exploration and funded a pre-feasibility study. It holds an Inferred JORC resource of 8.4Mt @ 1.1% Cu (88.6kt contained copper) across seven deposits over 7,508km² of tenure; exploration is early-stage regional target generation (50+ untested copper breccia pipes identified, only 7 drill-tested to date). No debt is reported.
Lifecycle Milestones
Jurisdiction (40%)9/10
Western Australia: Fraser PPI 2025 is 88.53 of 100 (rank 13 of 68), which maps to 9 on this site's scale. Southern Cross Greenstone Belt, Western Australia — a top-tier mining jurisdiction.
Infrastructure (40%)No verified figure
Researched with nothing found: no source we could cite confirms or rules out an existing mill, road access, grid power, or tailings facility at Hopes Hill Project (Southern Cross Gold Project Tenure), Western Australia (checked Oct 1, 2026; recheck due Mar 30, 2027). Counts at a neutral 5/10 until one does.
Nearby producing mine (20%)Not yet researched
No project coordinates on file yet, so distance to a producing mine can't be measured.
Acquisition Susceptibility
A relative ranking of how closely this company matches the profile of juniors that have actually been acquired — not a probability, and not a reason to buy. Acquisitions are rare: only a few dozen significant deals happen a year across a universe of thousands of juniors, so even a high score here describes a long shot. The strongest signal in the research, a producer that already owns part of the company, is scored from its disclosed strategic shareholders. A producer that is a joint-venture or earn-in partner on the project, rather than a shareholder, isn't captured yet.
How this score is built
- Disclosed pending dealSub-score: Not scored
No pending acquisition or merger disclosed (checked)
Not scored: having no deal in flight isn't held against a company.
Weight 26.25% - Producer's strategic stakeSub-score: Not scored
No producer holds a disclosed stake on file (holder register researched) See holders
Not scored: most juniors that do get bought had no prior toehold, so a missing stake says little either way.
Weight 25% - Distance to a producing mineSub-score: Not yet researched
Distance not yet researched: no project coordinates on file
Distance can't be measured without coordinates, so excluded rather than counted as far.
Weight 22.5% - Lifecycle stageSub-score:1/10
Stage: Grassroots Exploration
Feasibility and permitting score 10, where deals cluster, and production 5.5; earlier stages score less, down to 1 at grassroots.

Golden Horse Minerals, renamed from Altan Rio Minerals in July 2023, explores the Hopes Hill project within its Southern Cross gold project tenure in Western Australia, and also owns the Sorrel copper project in the Northern Territory's McArthur Basin, bought from NT Minerals in September 2025. More than 50,000 m of drilling in the first half of 2026 extended the Hopes Hill system beyond 3 km of strike, open along strike and at depth, with intercepts including 16 m at 6.8 g/t gold and, at the Hopes Hill North step-out, 12 m at 7 g/t gold. There is no mineral resource at Hopes Hill yet, and the company is guiding to an inaugural estimate in the second half of 2026. Sorrel holds an inferred JORC resource of 8.4 Mt at 1.1% copper, about 88.6 kt of contained copper, across seven deposits.
