1.58Mt Bluebird resource anchors Tennant Minerals’ FY2026 report

Auditor highlights funding dependence

Tennant Minerals Limited (ASX:TMS) has put a promising exploration year on the books, but the most consequential line in its FY2026 annual report is not a drill result. Horizon Nexus (WA) Audit Pty Ltd issued an unmodified audit opinion while drawing attention to a material uncertainty related to going concern, citing the group’s $844,721 loss and $1.03 million operating cash outflow for the year ended 30 June 2026.

The warning does not mean the accounts were qualified. It does, however, underline the company’s dependence on equity markets while it remains pre-revenue. Tennant held $1.44 million in cash and cash equivalents at year-end, alongside a $1.27 million working-capital surplus. The directors relied partly on the subsequent receipt of a further $1.2 million from the second tranche of a capital raising, as well as the company’s ability to raise additional equity.

Bluebird resource establishes a high-grade base

Against that financial backdrop, the geological numbers are substantial for an exploration company. Tennant’s maiden open-pit Mineral Resource Estimate for part of the 100%-owned Bluebird discovery totals 1.58 million tonnes at 3.00% copper equivalent, containing 47,400 tonnes of copper equivalent. The estimate includes 1.07 million tonnes in the Indicated category at 3.43% copper equivalent and 510,000 tonnes Inferred at 2.08%.

The resource is limited to mineralisation considered to have reasonable prospects of economic extraction by open-pit mining and centralised processing, extending to 180 metres below surface. Tennant says about 78% of contained copper-equivalent metal sits in the Indicated category. Previous metallurgical work reported copper recoveries of up to 90% into concentrates grading between 24% and 29% copper, while gold recoveries to copper concentrate reached up to 79% in the reported tests.

New drilling pushes high-grade zone deeper

Diamond drilling completed during the year added weight to the case for extensions below the current resource envelope. Hole BBDD0050 returned an 18-metre interval at 10.0g/t gold equivalent from 178 metres downhole, including 4.55 metres at 34.3g/t gold equivalent and a 0.55-metre sub-interval grading 47.2g/t gold, 9.3% copper and 12.0% bismuth. Re-assaying of high-grade samples confirmed the reported results, according to the company.

The intersection sits below the optimised pit shell used in the resource evaluation. Tennant says mineralisation remains open down-plunge to the west and at depth, with the broader Bluebird-Perseverance corridor still being assessed for extensions and additional discoveries. Those claims remain exploration interpretations rather than a formal underground resource.

Processing study adds regional development angle

Tennant is also participating in the Tennant Creek Copper Alliance, a joint operation with other Northern Territory exploration groups assessing a multi-user processing facility for copper, gold and critical minerals. The Alliance received $600,000 in combined Federal and Northern Territory government grants, with member companies matching the contribution and funding additional study costs.

The feasibility-level work is examining plant configuration, capital and operating costs, infrastructure, products, approvals and ownership structures. Final engineering outcomes are expected during or shortly after the September 2026 quarter. For Tennant, a shared facility could provide an important processing pathway, but the study is not a development decision and does not remove the need for further funding, approvals or technical work.

Capital raise expands funding and securities count

The company reported firm commitments for a $2.8 million raise to fund exploration and development. Tranche 1 proceeds were received during FY2026, while the second tranche was completed after shareholder approval in July, involving 164.3 million placement shares and 734.7 million listed options. As at 26 August, Tennant had 1.50 billion ordinary shares on issue, alongside more than 1.00 billion listed options and 88 million unlisted options.

That financing gives Bluebird another phase of drilling and study work to pursue, but it also leaves the investment case balanced between geological progress and financial endurance. The next test is whether follow-up drilling, metallurgy and the regional processing study can convert a high-grade exploration story into a clearer development proposition before the company needs to return to the market.
