New board moves fast as Tartana resets its exploration strategy

Following the 17 August 2026 Extraordinary General Meeting (EGM) that delivered a decisive mandate for change, Tartana Minerals (ASX: TAT) has moved quickly under new Executive Chairman Sonny Didugu. A wide-ranging corporate and strategic review is underway across operations, finances, governance, and the tenement portfolio. The most immediate catalyst for investors is the first drilling at Nightflower since 2008, targeted for October 2026.

What the new board is doing — and doing quickly

Strategic review covers operations, governance and the asset portfolio

The board’s review spans four distinct areas: operations, financial position, corporate governance, and the tenement portfolio. The company holds four JORC (2012) Mineral Resource Estimates across copper, gold, and zinc at the Tartana Mining Leases, Cardross, and Mountain Maid. A comprehensive desktop geological review of all historical exploration data is underway across the entire portfolio, supported by on-ground field reconnaissance on priority tenements.

The goal is an informed, sequenced approach to future exploration priorities rather than the prior intention to drill at least 10,000 metres in 2026 across prospects predominantly targeting silver and gold, which did not proceed. To date, approximately 1,500 metres of resource extension drilling have been completed at Tartana Copper.

ALT Resources deal terminated

The new board has moved to close out a legacy transaction. All discussions with ALT Resources PLC have been terminated, with the Letter of Offer having expired and the transactions never progressing beyond an indicative, non-binding phase.

The terminated proposal would have seen the company sell a 50% interest in its wholly-owned subsidiary Queensland Strategic Metals Pty Ltd in exchange for A$2 million in ALT Resources scrip (contingent on an AIM listing), plus a A$500,000 convertible note to fund exploration, as well as potential royalty funding arrangements. The new board determined the transactions are not in the best interests of shareholders and are not value-accretive.

The board’s immediate priorities are:

  • Complete the corporate and strategic review
  • Advance drilling and exploration
  • Finalise an independent review of the copper sulphate plant

Nightflower silver project — first drilling since 2008 set for October

The key milestone here is land access. Under new management, a Conduct and Compensation Agreement has been finalised and executed at Nightflower — a key prerequisite for drilling that had not been previously completed. Access roads are now being cleared to mobilise Tartana’s truck-mounted drill rig to the site, with drilling targeted for October 2026.

Nightflower hosts an Exploration Target for its northern prospect, Digger Lode, and a potential southern extension known as Terrace Lode, which has not been drilled since 1990. Investors should note the mandatory regulatory qualification: the Exploration Target is conceptual in nature, insufficient exploration has been completed to estimate a Mineral Resource, and there is no certainty that further exploration will result in a Mineral Resource estimate.

The Conduct and Compensation Agreement also covers the nearby OK Mines and Bellevue projects. For the first time since the OK Mine was discovered in the early 1900s, all historic mines within the OK district are consolidated under a single tenure, enabling a coordinated exploration approach across the district.

Sonny Didugu, Executive Chairman

“Securing land access arrangements at Nightflower — our most prospective silver project — and immediately commencing road access works, is an important milestone towards the first drilling on this project since 2008.”

Understanding base and precious metals exploration — why portfolio scale matters

In junior mining, a larger tenement portfolio means more shots at discovery and a spread of risk across multiple targets. No single drill hole defines a company’s outcome; what matters is having credible targets, the access to drill them, and the capital discipline to sequence exploration sensibly.

A Conduct and Compensation Agreement is a legal arrangement between a mining company and landholders (often pastoralists or traditional owners) that establishes the terms under which exploration activities can take place on their land. Without one in place, a company legally cannot commence drilling, regardless of how prospective the ground may be. Securing this agreement at Nightflower was therefore a non-negotiable step before any drilling could proceed.

Tartana holds one of the largest tenement positions in the Chillagoe and Herberton regions of Far North Queensland, with multiple exploration-stage prospects across base metals (copper, zinc) and precious metals (silver, gold). That portfolio breadth is what gives the new board options as it sequences its exploration programme.

Copper sulphate plant under independent review alongside exploration push

The copper sulphate plant has produced minimal output in 2026 despite significant refurbishment expenditure, including replacement of the chiller circuit and restacking of 50,000 tonnes of material on the heap. An independent technical review commenced this week, covering refurbishment works, heap performance, operational constraints, and the project’s short and long-term economic potential.

The plant’s commercial context is worth understanding. Historically, it has generated $3.2 million in revenue over a 24-month production period. All production is committed under a 100% offtake agreement with Kanins International, with the copper sulphate sales price calculated with reference to the LME Copper price, which has recently settled above US$14,000 per tonne (approximately AU$19,000). The board’s stated objective is to ensure further investment in copper sulphate production is economically sustainable and profitable before committing more capital.

Frequently Asked Questions

What is a Conduct and Compensation Agreement in Australian mining?

A Conduct and Compensation Agreement is a legal arrangement between a mining company and landholders — such as pastoralists or traditional owners — that establishes the terms under which exploration activities can take place on their land. Without one in place, a company cannot legally commence drilling, regardless of how prospective the ground is.

Why did Tartana Minerals terminate the ALT Resources deal?

The new board determined the proposed transaction — which would have sold a 50% interest in Queensland Strategic Metals Pty Ltd for A$2 million in ALT Resources scrip (contingent on an AIM listing) plus a A$500,000 convertible note — was not in the best interests of shareholders and not value-accretive. The Letter of Offer had already expired and the deal had never progressed beyond a non-binding, indicative phase.

When is Tartana Minerals planning to drill at Nightflower?

Tartana Minerals is targeting October 2026 for the first drilling at the Nightflower silver project since 2008. Access roads are currently being cleared to mobilise the company's truck-mounted drill rig to the site following the execution of a Conduct and Compensation Agreement.

What is the copper sulphate plant's commercial arrangement and why is it under review?

The copper sulphate plant operates under a 100% offtake agreement with Kanins International, with pricing referenced to the LME Copper price — recently above US$14,000 per tonne. Despite generating A$3.2 million in revenue over a prior 24-month production period, the plant has produced minimal output in 2026 after significant refurbishment expenditure, prompting an independent technical review to assess whether further investment is economically justified.

What JORC resources does Tartana Minerals hold across its portfolio?

Tartana Minerals holds four JORC (2012) Mineral Resource Estimates covering copper, gold, and zinc across the Tartana Mining Leases, Cardross, and Mountain Maid projects in the Chillagoe and Herberton regions of Far North Queensland. A comprehensive desktop geological review of all historical exploration data is currently underway across the full portfolio.
