Antipa extends Tim’s Dome gold–copper zone: resource and targeting notes for planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Antipa Minerals has extended gold–copper–lead–silver mineralisation over more than 1km of strike at the Tim’s Dome prospect in Western Australia, based on assays from five reverse circulation holes drilled above a large, untested airborne electromagnetic (AEM) conductor. The results form the third assay batch from the current RC programme and precede planned diamond drilling directly into the AEM target. For geologists and mine planners, the scale of the multi-commodity system plus the untested conductor point to significant upside for both resource definition and potential underground targets.
Technical Brief
- RC drilling above the AEM conductor targets sulphide-associated mineralisation potentially enhancing conductivity contrast.
- AEM anomaly remains unpenetrated by drilling, preserving potential for deeper, higher-grade sulphide zones.
- Sequencing RC ahead of diamond coring allows refinement of collar locations and azimuths for core holes.
- Planned diamond drilling into the conductor will provide oriented core for structural and geotechnical logging.
- Core data from the conductor zone will enable more robust density, metallurgical and rock-mass characterisation.
- For similar mining projects, untested AEM conductors beneath known mineralisation often become priority underground targets.
Our Take
Tim’s Dome adds another gold–copper target to Antipa Minerals’ Western Australian portfolio, which our database already shows is anchored by the advancing Minyari Dome project where recent work has confirmed conventional processing routes; this diversification can help de-risk dependence on a single asset in the Paterson Province.
The more than one kilometre of strike tested at Tim’s Dome, off only five reverse circulation holes, suggests Antipa may be in an early-stage resource definition phase similar to where Minyari sat ahead of its February 2026 discovery update, implying scope for follow-up infill and step-out drilling if continuity holds.
