Minyari Dome development: geotechnical and pit design notes for mine planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Antipa Minerals has advanced pre-feasibility work on its 100 per cent-owned Minyari Dome gold–copper project in Western Australia’s Paterson Province, progressing mining studies, metallurgical testwork and process plant design. Current workstreams include pit optimisation, geotechnical and hydrogeological modelling, and detailed analysis of gold–copper recoveries from sulphide mineralisation to refine a conventional crush–grind–flotation flowsheet. Outcomes will drive updated resource-to-reserve conversion, mine scheduling and capital estimates, with particular focus on pit wall stability, dewatering requirements and plant throughput options.
Technical Brief
- Project remains 100 per cent owned by Antipa Minerals, outside existing Paterson joint venture structures.
Our Take
Minyari Dome adds to a dense pipeline of Australian gold stories in our database, which also includes exploration-stage assets like Minerals 260’s Bullabulling project, signalling that Western Australia remains a focal point for new gold project development rather than just brownfields expansions.
As a gold–copper asset, Minyari Dome sits within a smaller subset of our 158 gold- and copper-keyword pieces, where most Australian coverage is still skewed to single-commodity gold projects; this polymetallic profile could improve project economics and resilience across price cycles.
Compared with recent gold-only corporate moves such as Westgold Resources’ planned spin-out of its Murchison assets into Valiant Gold, Antipa Minerals is pursuing value through project advancement rather than portfolio restructuring, which may appeal to investors looking for direct leverage to a specific development asset.
