Tartana Minerals has kicked off a drilling campaign aimed at increasing its copper resource and completed a $3.8 million capital raise amid operational challenges at its Copper Sulphate plant. A strategic placement with Xingye Gold Mining, conditional on shareholder approval, promises fresh capital and potential collaboration.
- Drilling underway to boost copper resource beyond 45,000 tonnes
- Copper Sulphate plant upgrades completed but production remains minimal
- $3.8 million equity raised during Q4 FY26
- Strategic placement with Xingye Gold announced post-quarter
- Governance shake-up with Executive Chairman appointment and upcoming EGM
Drilling Campaign Targets Copper Resource Growth
Tartana Minerals (ASX:TAT) has commenced drilling operations on its Tartana mining leases using a newly acquired UDR650 rig, completing 1,208 metres so far. The program aims to increase the existing copper resource of 45,000 tonnes at 0.45% copper, targeting extensions both along strike and at depth to 130 metres. While assays are pending, the campaign builds on the company’s 2023 resource estimate and is designed to underpin future mine planning and potential production growth.
The drilling initiative follows earlier announcements outlining the company’s intent to more than double contained copper through systematic exploration, with the rig enabling efficient deep hole completions. Visual core images have been released but the company cautions these are not indicative of mineralisation without laboratory confirmation.
Copper Sulphate Plant Upgrades Yield Limited Production
Despite significant capital expenditure earlier in 2026, including new chiller installations and stacking 50,000 tonnes of material on heaps to enhance heap leach copper recovery, Tartana’s Copper Sulphate plant has produced only minimal output this year. The company is considering commissioning an external technical review to assess the plant’s long-term viability, including whether recent stacking adhered to hydro-metallurgical recommendations.
Production is expected to remain minimal for the remainder of 2026, raising questions about the plant’s operational efficiency and its role in the company’s near-term cash flow strategy.
Capital Raising and Cash Position
Tartana raised $3.804 million in equity during the quarter, primarily through the second tranche of a $4.5 million raise announced in February, alongside director participation from previous placements. The company ended the quarter with just $261,000 in cash and reported an estimated funding runway of just 0.12 quarters at current cash burn rates, primarily due to one-off payments to directors, related parties, and creditors, as well as operational expenditures.
With Copper Sulphate production falling short of expectations, Tartana acknowledges it will rely on further capital raisings to fund operations, including a proposed $5.2 million strategic investment by Xingye Gold Mining announced post-quarter. This placement, priced at $0.053 per share, represents a substantial premium to recent trading and would grant Xingye a 19.99% stake, subject to shareholder approval at an upcoming Extraordinary General Meeting.
Governance Changes and Strategic Review
In July, Tartana appointed Sonny Didugu as Executive Chairman, supported by directors Michael Thirnbeck and Kiara Wang. This leadership shift coincides with a shareholder meeting called to vote on the removal of certain directors, reflecting ongoing governance tensions. The Executive Chairman has initiated an internal operational and strategic review focused on cutting overheads, scrutinising historical expenditures, and prioritising future investments.
This review includes a technical assessment of the Copper Sulphate plant and the company’s broader exploration portfolio, aiming to address operational challenges and improve capital allocation efficiency.
Related Party Transactions and Disclosure Concerns
Tartana disclosed payments totalling $859,028 to related parties during the quarter, including remuneration to directors and payments for corporate services and equipment hire. Notably, the company flagged a potential undisclosed redemption of $100,000 worth of convertible notes held by director Stephen Bartrop, which may represent a related-party transaction that was not timely reported to the ASX. This issue raises questions about compliance and transparency around securities interests and convertible note reductions.
Bottom Line?
Tartana’s drilling push and strategic investment offer fresh momentum, but operational setbacks and governance disputes add uncertainty to its path forward.
Questions in the middle?
- Will assay results from the current drilling campaign confirm a meaningful increase in copper resources?
- Can the upcoming strategic placement with Xingye Gold secure the funding needed to stabilise operations?
- How will the outcome of the director removal vote impact Tartana’s governance and strategic direction?
