Antipa Minerals has extended gold-copper-lead-silver mineralisation across 2.2km at Tim’s Dome, sharpening focus on a large untested electromagnetic conductor. Surface diamond drilling is now underway on the 1.2km target, which remains unproven despite encouraging surrounding assays.
- Mineralisation extended across approximately 2.2km of strike
- Untested AEM conductor measures 1.2km long and up to 470m wide
- Best results include 26m at 0.44 g/t gold and 2,345ppm copper
- Surface diamond drilling has begun after failed RC diamond tails
- A$180,000 WA Government grant awarded for Tim’s Dome drilling
Tim’s Dome footprint reaches 2.2km
Antipa Minerals Ltd (ASX:AZY) has widened the interpreted mineralised footprint at Tim’s Dome to approximately 2.2km of strike, with the latest 13 reverse-circulation holes returning gold, copper, lead and silver mineralisation. The results come from 3,073 metres of drilling within the company’s 100%-owned Minyari Project in Western Australia’s Paterson Province.
The strongest intersections were broad rather than uniformly high grade. Hole 26XTDC0068 returned 30 metres at 0.46 g/t gold from 180 metres, including 3 metres at 1.74 g/t and a 1-metre interval at 3.53 g/t. Hole 26XTDC0074 delivered 20 metres at 0.49 g/t gold from 36 metres, including 1 metre at 6.50 g/t, while 26XTDC0078 intersected 26 metres at 0.44 g/t gold and 2,345 parts per million copper from 214 metres, including 7 metres at 1.17 g/t gold and 2,774ppm copper.
Those intervals are reported down-hole, and true widths are not always known. The batch’s peak one-metre assays were 8.11 g/t gold, 0.65% copper, 0.54% lead and 2.08 g/t silver, with elevated arsenic, bismuth and antimony also recorded. Antipa interprets the lead and pathfinder signature as part of a broader intrusion-related system, but that interpretation remains an exploration thesis rather than a resource conclusion.
Large conductor moves to the centre of the programme
The more consequential target sits beneath the new drilling. The bedding-parallel AEM conductor extends for roughly 1.2km, measures between 200 and 470 metres wide, and is interpreted to begin around 270 to 340 metres below surface. It remains completely untested.
Several of the latest RC holes intersected mineralisation above or adjacent to the conductor, while other holes identified reef-style mineralisation between about 50 and 130 metres from Tim’s Dome’s existing 110,000-ounce gold resource. The company says the pattern supports further testing of a potential Telfer-style reef system, although the conductor itself could still prove to be something less economically significant than the surrounding geology suggests.
Two attempts to extend RC holes with diamond tails were unsuccessful. Antipa has instead started diamond coring from surface, with a WA Government Exploration Incentive Scheme grant of A$180,000 helping fund the work. That drilling is the clearest near-term test of whether the geophysical anomaly contains a substantial mineralised body or merely sits alongside one.
Drilling continues across Minyari
The broader CY2026 Phase 1 programme has completed 314 holes for 37,225 metres against a planned 321 holes and 41,000 metres. The air-core campaign has finished, while RC drilling continues at Minyari Dome and two rigs remain active across Tim’s Dome and Minyari Dome. Assays from the remaining 129 metres of hole 26XTDC0080 are still pending.
Antipa is also preparing follow-up RC work at AL01, planning future diamond drilling at Mollie and continuing discovery and resource-growth drilling around the Minyari Dome deposits. The company says the programme is funded from existing cash, supplemented by the EIS grants, but the next meaningful value test is narrower: whether surface diamond drilling can convert an impressive-looking conductor and its surrounding anomalies into continuous, sufficiently wide and sufficiently high-grade mineralisation.
Bottom Line?
The headline target is still untouched. Surface diamond drilling, pending assays and any resulting resource update will determine whether Tim’s Dome is a growing satellite resource or a more ambitious discovery story.
Questions in the middle?
- Will diamond drilling intersect substantial gold-copper mineralisation within the 1.2km AEM conductor?
- How closely will future drilling establish the true widths and continuity of the reported down-hole intervals?
- Can Tim’s Dome’s surrounding mineralisation support a maiden or expanded resource opportunity beyond its existing 110,000-ounce resource?
