Tartana Minerals (ASX:TAT), formerly R3D Resources, is a small copper producer in far north Queensland that announced a A$5.18 million strategic investment from Xingye in July 2026. The company pairs early-stage Operating Revenue from copper sulphate with a funding event; beyond a substantial holder notice, the full completion of that investment has yet to be set out in detail.

What the company does

Tartana is a copper producer and a copper, gold, silver and zinc explorer in the Chillagoe region of far north Queensland, according to the company. It lists its Tartana copper sulphate pentahydrate project as producing or near-producing. Its portfolio also includes a Tasmanian zinc slag project, mining Lease applications at Cardross and Mountain Maid, and several exploration projects.

Production and funding to April 2026

In an April 2026 corporate presentation, the company said copper sulphate revenue to date was US$3.7 million over 18 months, at an operating cash Margin it put above 40 per cent. Production in the second half of 2025 was lower because of lower feed grades. About 50,000 tonnes of mineralised pit Fill had been stacked on the leach pad, and leaching was starting. These are company statements; reported sales represent revenue, while drilling plans are not outcomes.

The presentation also referred to a A$4.5 million raising led by Alpine Capital, announced in February 2026, and gave pro forma shares on issue of 391,146,105 at A$0.025. Shareholders had approved refinancing unsecured loans into A$1.2 million of convertible notes that convert at A$0.10 a share. The company planned about 21,000 metres of drilling across its projects using a newly acquired rig, and cited a Queensland A$275,000 exploration grant for an 800 metre hole at Beefwood.

July 2026 events

The company's announcements show a busy fortnight in July. On 9 July it announced a restart of copper sulphate production and changes to board leadership. On 10 July it issued a notice of an extraordinary general meeting, followed by a pause in trading and then an unsolicited indicative strategic investment proposal.

On 17 July Tartana announced a A$5.18 million strategic investment from Xingye at 5.3 cents per share, together with a proposed issue of securities. By simple arithmetic, that equates to about 97.7 million shares, subject to the deal's terms, conditions and any Shareholder approval requirements. A substantial holder notice dated 11 August 2026 shows Xingye Gold (Hong Kong) Mining Company Limited holding 43,460,678 shares, or 9.99 per cent. The company released a Quarterly Report on 31 July 2026.

Risks

Copper sulphate output depends on feed grades, leach performance and plant reliability, as the dip in the second half of 2025 showed. Exploration programs require funding, and the issue of shares at 5.3 cents, convertible notes at 10 cents and Options all affect dilution. No operational agreement with Xingye has been announced.

What's Next

The points to follow are the completion of the remaining Xingye investment, including any shareholder approvals, the performance of the restarted copper sulphate operation and progress on the planned drilling program, including the Beefwood hole.
