Antipa Builds Minyari Case as Resource and Processing Work Advance

Antipa Minerals has expanded its Minyari Project resource to 3.6 million ounces of gold equivalent and advanced key pre-feasibility work, including conventional processing and deeper open-pit studies. The progress comes with an auditor-highlighted going-concern uncertainty as the company prepares for further exploration and development spending.

  • Minyari Project resource rises to 69Mt at 1.33g/t gold, or 3.6Moz AuEq
  • A$39.1m cash balance against A$38.3m FY2026 operating and exploration outflows
  • PFS work supports conventional gold-copper processing and deeper open-pit evaluation
  • Tim’s Dome drilling outlines 1,040m of mineralisation above an untested conductor
  • Auditor flags material uncertainty over future funding requirements

Minyari Resource Reaches 3.6Moz Gold Equivalent

Antipa Minerals Limited (ASX:AZY) has used its 2026 annual report to put a larger number around its Minyari ambition: the 100%-owned Western Australian project now carries 69 million tonnes at 1.33 grams per tonne gold, containing 2.9 million ounces of gold, 91,000 tonnes of copper, 880,000 ounces of silver and 13,000 tonnes of cobalt. On the company’s stated assumptions, that equates to 3.6 million ounces of gold equivalent.

The quality of the resource has also improved. About 76% of contained gold across the project is classified as Indicated, while Minyari Dome contains 2.5Moz of gold with roughly 85% in the Indicated category. The dominant Minyari deposit contains 1.9Moz, of which about 97% is Indicated. Those figures provide a stronger technical base for mine planning, although they remain Mineral Resources rather than Ore Reserves.

PFS Work Moves From Drilling to Mine Design

During FY2026, Antipa completed 615 holes for approximately 62,000 metres as it worked on resource definition, exploration and the technical studies needed for the Minyari Dome pre-feasibility study. The programme covered geotechnical drilling, hydrogeology, metallurgy, mine planning, infrastructure, environmental approvals, heritage and financing preparation.

Post year-end metallurgical work found gold recoveries of about 89% to 98% across oxide, transitional and primary material at a 75-micron grind. Primary material was described as free milling and non-refractory, supporting conventional carbon-in-leach processing to gold doré, alongside the potential for a separate copper concentrate grading approximately 22% copper. Updated geotechnical parameters also support evaluation of steeper pit walls and deeper open-pit mining. These inputs are still being incorporated into the PFS mine plan, processing flowsheet, cost model and development schedule.

Exploration Keeps the District-Scale Option Alive

The development study is running alongside a broad exploration campaign. At Tim’s Dome, southwest of Minyari and along strike from Telfer, drilling identified gold-copper-lead-silver mineralisation over approximately 1,040 metres of strike. The mineralisation sits above a bedding-parallel airborne electromagnetic conductor extending about 1.2 kilometres, which initial reverse-circulation drilling could not reach because of groundwater conditions. Diamond drilling is being used to test the deeper target.

Other FY2026 and post-year-end results extended mineralisation at Fiama, Fiama North and GEO-01, while the company identified new copper and gold-copper anomalies at Yolanda and AL01. Antipa says any discoveries near Minyari could potentially add to mine life, development scale or infrastructure utilisation, but the report does not establish that these targets will become economic deposits.

Cash Runway Remains the Immediate Constraint

The financial statements show the familiar arithmetic of an explorer moving toward development: Antipa recorded a A$5.95 million net loss for FY2026 and spent A$36.5 million on capitalised exploration and evaluation activities. The company finished June with A$39.15 million in cash after raising A$40 million through a placement and a further A$3.35 million from option exercises.

That balance does not remove the funding question. BDO highlighted a “material uncertainty” related to going concern because Antipa’s continued operations and planned exploration depend on managing available capital and raising additional funds if required. The company’s directors said they believe further capital can be raised, but no financing package or development funding commitment has been disclosed. The PFS therefore has two jobs: establish whether Minyari can be built on acceptable technical and economic terms, and clarify how much capital the next stage will require.

Bottom Line?

The resource and technical foundations are strengthening, but the next PFS must convert that progress into an investable mine plan without stretching the balance sheet.

Questions in the middle?

  • What capital and operating costs will the completed Minyari PFS assign to the project?
  • How much of the expanded Mineral Resource can be converted into Ore Reserves?
  • Will Tim’s Dome drilling confirm a deeper mineralised system, or remain an exploration possibility?
