Black Cat high-grade gold at Coyote Central: design and cut-off notes for mine planners
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Black Cat Syndicate has reported high-grade gold intercepts up to 47.05g/t from a seven-hole, 4000m diamond drilling programme targeting the Axial Core Zone at its Coyote Central underground operation in Western Australia’s Tanami region. Drilling has also defined a new exploration target at depth beneath existing workings, suggesting potential down-plunge extensions to the current resource envelope. For mine planners and geotechs, the deeper target will likely require updated geotechnical models, revised ground support designs and reassessment of economic cut-off grades at Coyote.
Technical Brief
- Drilling targeted the Axial Core Zone, implying structurally controlled mineralisation aligned with the fold hinge.
- High-grade intercepts such as 47.05g/t Au suggest narrow but very rich quartz-vein domains.
- Core recovery and structural logging from this programme will materially refine local geotechnical domains and fabric.
- Deeper intercepts beneath current levels indicate potential requirement for extended decline or winze development.
- Any expansion of the underground front will need reassessment of ventilation, pumping and emergency egress capacities.
- Similar Tanami-style lode systems often demand tighter stope dilution control and more selective mining methods at depth.
Our Take
Black Cat Syndicate’s high-grade hit at Coyote Central in the Tanami adds to a run of strong intercepts at Paulsens and Trojan in Western Australia, suggesting the company is systematically building a multi-asset high-grade gold portfolio rather than relying on a single flagship mine.
The 4000m, seven-hole diamond programme at the Coyote gold operation fits with Black Cat’s recently flagged plan (up to $35 million FY2027 budget) to prioritise resource conversion drilling, indicating Coyote could soon move from exploration success towards more formal resource definition work.
With Macmahon already providing underground services at Black Cat’s Majestic gold mine, any future underground development at Coyote Central or the Axial Core Zone would likely be able to leverage existing contractor relationships and cost benchmarks from other Western Australian gold operations in our database.
