HIGHLIGHTS

  • TMS shares surged 42.86% to AUD 0.013 on 7 May 2026 on exceptional diamond drill results at Bluebird including 18m at 10.1g/t AuEq, with peak grades of 42.6g/t gold, 12.2% bismuth, and 9.6% copper.
  • Bismuth is currently trading at over US$60,000 per tonne on global markets due to Chinese export restrictions, materially enhancing the economic significance of bismuth-bearing intersections at Bluebird.
  • Tennant Minerals has completed a A$2.8 million Capital raise to accelerate exploration including drilling of shallow plunging extensions to the Bluebird high-grade zone, with drilling set to commence within weeks.

 

Tennant Minerals Limited (ASX:TMS) delivered one of the more dramatic single-session performances on the ASX on 7 May 2026, with its shares surging 42.86% to AUD 0.013 on Volume exceeding 21 million shares. The catalyst can be a combination of exceptional diamond drill results at the Bluebird discovery within the company's 100%-owned Barkly Project in the Northern Territory's Tennant Creek region, complemented by the announcement of a A$2.8 million capital raise to fund the next phase of exploration.

While the absolute share price remains in Penny Stock territory — a reflection of the company's early exploration stage and relatively modest Market Capitalisation of approximately A$7.46 million — the percentage gain and the quality of the drill results attracted widespread attention from investors tracking the critical minerals and gold exploration space. The intersection in question — featuring high grades of gold, bismuth, and copper — has a quality that stands out even in a market where headline drill results are routinely promoted.

The Bluebird Drill Results: Understanding the Numbers

The results from diamond drill-hole BBDD0050 at the Bluebird deposit have delivered what management has characterised as exceptional and spectacular intersections. The headline result is an 18-metre intersection from 178 metres downhole grading 10.1 grams per tonne gold equivalent — a composite figure that incorporates gold, copper, and bismuth credits. Within this intersection, a higher-grade zone of 4.55 metres grades 34.5 grams per tonne gold equivalent, which itself contains a spectacular half-metre interval grading 42.6 grams per tonne gold, 9.6% copper, and 12.2% bismuth.

These are, by any standard, high-grade results for a base and precious metals exploration project. The grades are the result of a polymetallic intersection that combines three economically significant metals — gold, copper, and bismuth — each of which contributes materially to the calculated gold equivalent grade. The company has noted that the presence of coarse gold and native copper in some intervals will necessitate screened re-assaying of samples, with those results expected within one to two weeks of the announcement.

Importantly, the new intersection is located to the west and below the recently announced open-pit Mineral Resource at Bluebird, extending the known high-grade gold-copper-bismuth mineralisation in a direction that remains open. Gravity modelling indicates that the mineralised ironstone continues for over 400 metres west of the drilled high-grade zone within a shallowly plunging corridor — a geological projection that the company believes has the potential to more than double the Bluebird footprint.

Bismuth: The Critical Mineral Adding Exceptional Economic Weight

A dimension of the Tennant Minerals story that distinguishes it from standard gold or copper exploration narratives is the presence of bismuth as a significant co-product. Bismuth, historically a minor industrial metal, has become a focus of significant market attention following the implementation of strict export controls by China in 2025. As of 30 April 2026, bismuth was trading at approximately US$67,000 per tonne on global markets — a price level that makes high-grade bismuth intersections economically transformative in their contribution to overall value per tonne of rock.

The 12.2% bismuth grade in the spectacular half-metre peak intersection translates, at current spot prices, to a bismuth value alone of approximately US$8,174 per tonne of rock from that interval — before any contribution from the gold or copper content. While such peak values are not representative of the broader intersection grade, they illustrate the extraordinary Leverage that bismuth exposure provides to the overall economic case for Bluebird.

Tennant Creek has a historical context as a bismuth-producing region, and the combination of gold, copper, and bismuth at Bluebird mirrors the polymetallic mineralisation style that characterised several historically significant mines in the district. The company has noted that further metallurgical test-work focused on enhancing gold and bismuth recovery is planned as part of the ongoing exploration and pre-feasibility study process.

A$2.8 Million Capital Raise Funds the Next Chapter

Tennant Minerals announced on 5 May 2026 that it had received firm commitments for a A$2.8 million capital raise from sophisticated and professional investors. The proceeds are earmarked for a clearly defined set of activities: drilling to extend and define the high-grade gold-bismuth-copper zone, further metallurgical test-work to enhance gold and bismuth recovery, and geological modelling of the gravity, magnetics, and induced polarisation data across the 2.5-kilometre Bluebird-Perseverance corridor.

Drilling is expected to commence within weeks as weather conditions in the Northern Territory improve — a seasonal constraint familiar to investors in the region. The company has also submitted a request to the Northern Territory government for co-funding to test the exciting target zone projected by the gravity modelling to the west of the drilled high-grade zone, a submission that reflects the potential scale significance of the Bluebird system.

The new funding will additionally support pre-feasibility studies into a jointly funded processing plant through the Tennant Creek Copper Alliance, providing a potential pathway for the development of shared infrastructure that could materially reduce the capital requirements for any future production scenario at Bluebird.

Conclusion

Tennant Minerals' 42.86% single-session surge on 7 May 2026 is the market's direct response to a genuinely exceptional drill intersection that advances the case for Bluebird as a high-grade polymetallic discovery of potential significance. The combination of gold, copper, and bismuth — with bismuth trading near historically elevated prices due to Chinese export restrictions — creates an unusually compelling economic profile for the mineralisation encountered at depth. With the A$2.8 million raise providing the capital to follow up aggressively, and gravity modelling pointing to significant untested extensions, the Bluebird story is entering a potentially defining exploration phase.
