Black Cat Finds More Gold Beyond Trojan Resource Boundary
Black Cat Syndicate has extended gold mineralisation beyond the current resource boundary at Trojan after completing a 56-hole, 6,804-metre RC drilling program. The results support further drilling and a potential resource upgrade, although the new intercepts are exploration results rather than an updated Mineral Resource.
- 56 RC holes completed across northern and southeastern Trojan
- Mineralisation extended beyond the existing 202koz resource boundary
- Best results include 3m at 6.88g/t gold and 13m at 1.79g/t
- Further drilling planned to support resource and mine-life planning
Trojan Mineralisation Moves Beyond Resource Boundary
Black Cat Syndicate Limited (ASX:BC8) has pushed the known footprint of its Trojan gold deposit beyond the current resource boundary, with drilling extending mineralisation in both the northern and southeastern parts of the Kal East Gold Operation.
The 56-hole, 6,804-metre reverse circulation program targeted two different geological opportunities: deeper extensions to the steeply dipping lodes in the north, and shallow, flat-lying oxide zones to the southeast. Black Cat says both objectives were met, with results outside the existing 202koz resource at Trojan, which is reported at 1.1g/t gold and is 33% Indicated.
High-Grade Northern Hits Strengthen Growth Case
The northern drilling produced the strongest headline intersections. Results included 13 metres at 1.79g/t gold from 237 metres, 6 metres at 2.58g/t from 251 metres, 7 metres at 3.02g/t from 257 metres and 3 metres at 6.88g/t from 142 metres.
Those intersections sit outside the current resource model and extend the mineralised footprint around Trojan's high-grade central core. The company says the results are consistent with historical drilling in the area, but the reported widths are downhole lengths. True widths have not yet been determined, an important qualification when assessing the potential scale of the extensions.
Shallow Oxide Zones Target Initial Mine Area
The southeastern results were lower grade but potentially important to mine planning because they target shallow stacked oxide mineralisation. Intersections included 11 metres at 1.13g/t gold from 33 metres, 6 metres at 1.13g/t from 47 metres, 3 metres at 1.68g/t from 68 metres and 3 metres at 1.54g/t from 33 metres.
Managing director Chris Stone said this southeastern area is where the company envisions initial mining development. Trojan has a history of open-pit production, with 125,129 ounces mined between 2000 and 2004, and sits about 50 kilometres from Black Cat's Lakewood processing facility.
Next Drilling Step Is Resource Conversion
Black Cat plans more extensional drilling, primarily across the shallow southeastern oxide zones, alongside infill drilling intended to convert Inferred material to Indicated and support updated life-of-mine planning. The company has not yet published a revised resource or reserve based on these results.
That leaves the key question at the resource-estimation stage. The new drilling demonstrates mineralisation beyond the June 2026 model, but further work will need to establish continuity, true widths and whether the additional ounces can be classified and incorporated into a mine plan.
Bottom Line?
The drilling adds credible growth targets around a 202koz deposit, but the next resource update will determine whether the wider footprint becomes mineable inventory.
Questions in the middle?
- How much of the newly identified mineralisation can be converted into Indicated or higher-confidence resources?
- Will the shallow southeastern oxide zones alter the sequencing of Trojan's proposed initial mining development?
- When will Black Cat publish an updated Trojan resource and revised life-of-mine plan?
