Antipa Minerals (ASX:AZY) has announced it is preparing to test a large conductor at Tim’s Dome after drilling outlined broad gold–copper-lead-silver mineralisation over 500m of strike at the Western Australian target.
The mineralisation sits directly above an untested airborne electromagnetic conductor measuring 1.2km long and between 200–470m wide.
The top of the conductor lies 270–340m below surface and remains 50–100m beneath the limits of current drilling. Antipa says excessive groundwater prevented the reverse circulation (RC) rig from reaching the target.
The company says it plans to extend selected RC holes with diamond tails from mid-August. A $180,000 Western Australian Government Exploration Incentive Scheme grant will co-fund the drilling.
Assays cover 70 holes for 7,781m completed across Tim’s Dome, GEO-01, Minyari Dome, and AL01 under Antipa’s phase one 2026 drilling program.
Results from Tim’s Dome include 22m @ 0.90 grams per tonne gold (Au) and 0.14% copper (Cu) from 157m in hole 26XTDC0051, including 3m @ 4.40g/t Au and 0.05% Cu from 171m.
An overlapping zone returned 26m @ 0.14% Cu and 0.22% lead (Pb) from 163m to the end of the hole.
Hole 26XTDC0052 intersected 12m @ 0.50g/t Au and 0.32% Cu from 186m, including 4m @ 1.10g/t Au, 0.46% Cu, and 1.10g/t silver (Ag) from 187m.
Managing Director Roger Mason says the mineralisation profile, which includes “high-grade gold and copper”, supports Antipa’s view of the Tim’s Dome target.
“The geological setting, metal association, and scale of the underlying conductor support our interpretation that the drilling may be defining the upper expression of a larger Telfer-style reef system,” Mason says.
Tim’s Dome hosts a mineral resource estimate of 110,000 ounces of gold and lies 11km from Greatland Resources’ (ASX:GGP) Telfer gold-copper mine and processing facility.
Elsewhere, growth drilling at GEO-01 South returned 12m @ 1.30g/t Au and 0.08% Cu from 141m, including 5m @ 2.90g/t Au and 0.14% Cu from 142m.
A geotechnical hole at WACA intersected 114m @ 0.80g/t Au and 0.24% Cu from 7m, including 19m @ 3.10g/t Au, 1.09% Cu, and 1.10g/t Ag from 61m.
The company has completed 201 holes for 22,439m as part of the planned 321-hole, 41,000m phase one program, with three rigs operating at WACA, Tim’s Dome, and Chicken Ranch.
