Key Highlights

  • Core hole 25MYD0540 at Minyari returned 22m at 8.2 g/t gold and 0.35% cobalt from 100m, including 5.1m at 27.4 g/t gold and 1.04% cobalt.
  • Batch 5 covers 22 RC holes for 4,588m, three diamond core holes and 79 air core holes at Chicken Ranch.
  • GEO-01 Main Zone mineralisation was extended about 230m down dip and WACA about 80m down plunge.
  • A total of 330 Phase 1 holes for 42,248m have been completed, with two rigs active across the Minyari Project.

Antipa Minerals Ltd (ASX:AZY) has reported the fifth batch of assay results from its Phase 1 CY2026 drilling at the 100%-owned, 3,840km2 Minyari Gold-Copper Project in the Paterson Province of Western Australia. The headline intercept is 22m at 8.2 g/t gold and 0.35% cobalt from previously unsampled core at the Minyari deposit, including 5.1m at 27.4 g/t gold and 1.04% cobalt. Batch 5 comprises 22 reverse circulation holes totalling 4,588m at Tim's Dome and Minyari Dome, three diamond core holes at Minyari Dome and 79 air core holes at Chicken Ranch, reported on 28 October 2026.

High-Grade Gold From Unsampled Minyari Core

The Minyari result comes from diamond hole 25MYD0540, drilled in 2025 to test a fold-axis-controlled target at depth. The upper portion of the hole was not sampled at the time and was assayed this year during preparations for Definitive Feasibility Study metallurgical testwork. Beyond the 22m at 8.2 g/t gold from 100m, the hole returned 0.8m at 12.8 g/t gold from 116.4m and 1m at 15.8 g/t gold and 0.60% cobalt from 120m. Nearer the surface it recorded 8m at 1.5 g/t gold and 0.22% copper from 32m, including 1m at 10.6 g/t gold.

The company said the intersections confirm a shallow, north-plunging high-grade gold shoot at 25 degrees, previously identified by holes 15 to 40m away. The maximum single-metre grade from Minyari Dome in this batch was 82.2 g/t gold, 2.91% copper, 39.8 g/t silver and 0.18% cobalt. The Minyari Dome Mineral Resource Estimate contains 2.5Moz of gold, including 2.2Moz classified as Indicated, along with 87kt of copper and 729koz of silver, and it underpins the ongoing Pre-Feasibility Study.

Extensions at GEO-01, WACA and Rizzo

At GEO-01 Main Zone, hole 26XMDD0555 returned 26.6m at 1.4 g/t gold and 0.04% copper from 640.4m, including 18.9m at 1.8 g/t gold from 644.1m and 2.4m at 7.4 g/t gold from 658m. The company said this places mineralisation about 230m down dip of previously defined zones.

At WACA, hole 26XMDD0556 intersected 44m at 0.5 g/t gold from 386m, including 21m at 0.8 g/t gold, extending mineralisation about 80m down plunge to the north. Rizzo reported 12m at 1.3 g/t gold and 0.35% copper from 70m in 26XMDC1006, including 2m at 5.4 g/t gold, and the company noted that mineralisation there remains open.

Tim's Dome and Chicken Ranch

Tim's Dome is a satellite deposit 30km southwest of Minyari and 11km from Greatland Resources' Telfer mine, with a current Mineral Resource of 110koz of gold. Phase 1 drilling has identified multiple new zones over about 2.2km of strike along the eastern fold limb. Batch 5 returned gold, copper, lead and silver mineralisation over approximately 600m of strike above a 1.2km-long airborne electromagnetic conductor, including 9m at 1.5 g/t gold, 0.11% copper and 0.53% lead from 178m in 26XTDC0081 and 51m at 0.24% copper from 241m in 26XTDC0080. The maximum one-metre grades were 10.1 g/t gold, 2.51% copper, 1.47% lead and 6.4 g/t silver.

The conductor's upper surface is interpreted to lie 270m to 340m below surface, and two diamond holes are complete with a third nearing completion. The program is supported by an A$180k Western Australian Government Exploration Incentive Scheme grant.

Chicken Ranch, about 25km south of Minyari, holds a resource of 49koz of gold. Air core drilling targeted ground east and north of the existing 90m to 220m wide corridor and returned 14m at 2.1 g/t gold from 40m in 26XCRA0228, including 2m at 13.0 g/t gold from 48m. The maximum one-metre grade was 18.7 g/t gold.

Drilling Status After Batch 5

Phase 1 has now completed 330 holes for 42,248m, made up of 116 RC holes, 208 air core holes and five diamond core holes. Two rigs remain active, with diamond drilling continuing at Tim's Dome and RC drilling recently started at AL01. Managing Director Roger Mason said further assay results are due and that several programs are running in parallel.
