Antipa’s Tim’s Dome 2.2 km footprint: scale and mine-planning notes for engineers
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Antipa Minerals’ fourth batch of drilling at the Tim’s Dome prospect in Western Australia’s Paterson Province has extended the 2026 gold–copper mineralised footprint to roughly 2.2km of strike. The latest programme comprises 13 reverse circulation holes totalling 3073m, with drilling now progressing from surface to test a large deeper target beneath the known mineralisation. For geologists and mine planners, the expanded strike length and move to deeper testing signal potential for a larger-scale resource and future underground or bulk-tonnage scenarios.
Technical Brief
- RC drilling from surface allows cost-effective coverage before committing to deeper diamond tails.
- Step-out drilling pattern will heavily influence future resource domaining and pit/underground shell optimisation.
- Deeper target testing is critical for assessing bulk-tonnage versus narrow-vein underground development scenarios.
- For similar mining projects, staged RC then deeper testing is becoming standard for capital discipline.
Our Take
Our database shows a sequence of Tim’s Dome updates through 2026, with the August 31 item reporting >1km of strike; pushing the mineralised footprint to about 2.2km now suggests Antipa is steadily building the scale needed to consider Tim’s Dome alongside Minyari Dome rather than as a small satellite target.
The cluster of recent Minyari Dome pieces (resource upgrade on April 7, drilling start on April 20, and metallurgical work on July 7) indicates Antipa is de‑risking Minyari as a near‑term gold–copper development hub in the Paterson Province, with Tim’s Dome growth potentially feeding into a larger district‑scale development case.
