Breakthrough Minerals has extended copper-gold mineralisation beyond Turpentine’s existing resource model, with its northernmost hole returning 14 metres at 1.57% CuEq. The exploration progress comes alongside A$2.484 million in cash and a reported 0.81 quarters of funding based on recent outgoings.
- 14m at 1.57% CuEq at Turpentine, including 5m at 3.75% CuEq
- Mineralisation extended beyond the existing 101,000-tonne CuEq Turpentine resource
- Barbara drilling confirmed copper continuity at depth
- A$2.484 million cash balance at 30 September 2026
- Potential mining camp divestment being pursued to support funding
Turpentine drilling pushes beyond the resource model
Breakthrough Minerals Limited (ASX:BTM) has found more copper-gold mineralisation beyond the existing resource envelope at Turpentine, strengthening the case for further drilling at the company’s largest North Queensland asset. The northernmost hole in the September-quarter program, 26TUR009, returned 14 metres at 1.57% copper equivalent from 251 metres, including 5 metres at 3.75% CuEq.
The result builds on the September Turpentine extension results that previously reported the same high-grade interval and forms part of a broader run of intersections across nine holes. Other results included 17 metres at 1.24% CuEq in 26TUR002, 19 metres at 1.03% CuEq in 26TUR003 and 5 metres at 3.21% CuEq in 26TUR005.
Turpentine currently carries an Inferred Mineral Resource of 8.7 million tonnes at 1.16% CuEq, containing 101,000 tonnes of copper equivalent. Breakthrough said the drilling supports its interpretation of a northern, down-plunge continuation identified through gravity inversion modelling. That is exploration evidence, not yet a revised resource estimate: any increase in reported resources would require further drilling, interpretation and formal estimation.
Barbara confirms mineralisation at depth
At Barbara, the company completed its maiden diamond drilling program during the quarter. The strongest reported result was 35 metres at 1.34% copper from 204 metres in 26BAR001, including 18 metres at 2.18% copper and 11 metres at 3.02% copper.
Several deeper holes also intersected copper mineralisation, including a broad 73-metre interval at 0.22% copper in 26BAR009 from 503 metres downhole. Barbara’s existing resource stands at 6.5 million tonnes at 0.97% CuEq for 63,000 tonnes of contained CuEq, and the company said future work will focus on the northern extensions of the Barbara Shear Zone and nearby targets. Downhole electromagnetic surveys are planned to help identify additional opportunities.
Exploration momentum meets a short reported runway
The operational progress is accompanied by a sharper financing question. Breakthrough ended September with A$2.484 million in cash, down from A$5.562 million at the start of the quarter. It spent A$1.828 million on exploration and evaluation, while net operating cash outflow was A$1.229 million, producing total relevant outgoings of A$3.057 million for the quarter.
On that basis, the Appendix 5B reports an estimated 0.81 quarters of funding available. Breakthrough said the figure was distorted by recent drilling expenditure and that it would have more than two quarters of estimated funding if drilling costs were excluded. The company is also engaging with an interested party over a possible divestment of mining camp assets it considers surplus to requirements, but the filing does not describe a binding transaction or disclose expected proceeds.
Resource growth now depends on follow-through
Breakthrough’s North Queensland Copper-Gold Project contains 18.8 million tonnes at 1.07% CuEq for 200,000 tonnes of contained CuEq across Turpentine, Barbara, Mt Colin and other deposits. The September results improve the geological picture at two of those assets, but the next test is practical: whether the company can fund enough follow-up work to convert extensions beyond the current models into a larger, better-defined resource base.
Bottom Line?
The drilling has improved the exploration case, but the next catalyst may be funding rather than assays: follow-up work and any progress on the mining camp divestment will determine how quickly the extensions can be tested.
Questions in the middle?
- Will further Turpentine drilling lead to a formal increase in the 101,000-tonne CuEq resource?
- Can Barbara’s deeper mineralisation support a resource upgrade or expansion after planned geophysical work?
- Will the potential mining camp divestment provide enough cash to avoid a near-term capital raising?
