Antipa picks gold and copper route for Minyari as PFS moves to November
Antipa Minerals has selected a preferred processing and mine development configuration for its Minyari Dome project, combining gold doré with a separate copper concentrate. The decision advances the study, but pushes the pre-feasibility study release into November 2026 while costs and project economics are finalised.
- Preferred route combines CIL gold doré with copper flotation
- Five processing configurations assessed
- Mine studies targeted earlier higher-grade ore and lower early waste movement
- Final CAPEX, OPEX and economic model remain outstanding
- Minyari PFS now expected in November 2026
Preferred processing route selected
Antipa Minerals Ltd (ASX:AZY) has chosen a development pathway for its 100%-owned Minyari Dome Gold-Copper Development Project in Western Australia, settling on conventional CIL gold doré production followed by flotation of the primary sulphide ore residue to produce a separate copper concentrate. The choice gives the project a defined route for the final stages of its pre-feasibility study, although the key financial outputs are still to come.
The company assessed five configurations, ranging from CIL-only gold doré production to copper concentration alone and combinations involving gravity recovery. Antipa says the preferred option was selected on overall project economics rather than maximising recovery of any single metal, with capital requirements, operating costs, recoveries and product mix all considered.
Mine schedule targets earlier value
Mine scheduling studies examined how open-pit and underground operations could be integrated, including the timing of pre-production waste and ore mining, the sequencing of oxide, transitional and sulphide material, and the point at which underground capital would be deployed.
Antipa says the work focused on bringing higher-grade ore into the schedule earlier, reducing early waste movement, improving capital deployment and shortening payback. Those are study objectives rather than disclosed outcomes: the announcement does not provide a mine plan, production profile, recovery assumptions or revised project economics.
PFS release moves into November
The extensive option studies have extended the previously anticipated timing for the PFS, which is now expected during November 2026. Antipa is still finalising operating and capital costs, the detailed mine schedule and the economic model for the selected configuration.
That delay leaves the most consequential investor questions unanswered. No CAPEX, OPEX, NPV, IRR, payback period, production estimate or funding requirement has been released with the preferred route. The November timetable is also forward-looking, so the eventual PFS will need to show whether the selected gold-and-copper configuration translates into the stronger value and capital efficiency the company sought.
Bottom Line?
The route is now defined, but the investment case still depends on the November PFS converting that design choice into credible costs, production metrics and project economics.
Questions in the middle?
- What CAPEX and OPEX will the combined gold doré and copper concentrate route require?
- How much earlier will higher-grade ore enter the mine schedule, and what effect will that have on payback?
- Will the November PFS retain its timing and provide a funding pathway for development?
