Tartana Minerals
Investor Insight
Tartana Minerals is a new copper producer with strong cash flow and a substantial exploration footprint in a tier 1 mining jurisdiction. Tartana Minerals is creating shareholder value through investment in increasing its existing copper, zinc and gold resources and accelerating exploration of key projects within its highly prospective exploration portfolio. Tartana Minerals presents a compelling investment against a strong macroeconomic environment for copper.
Overview
Tartana Minerals (ASX:TAT) is a copper, gold, silver and zinc, producer, explorer and developer in Far North Queensland. Its flagship project is the 100 percent owned Tartana copper and zinc project which comprises four mining leases located north of Chillagoe. The company’s business model has involved refurbishing an existing heap leach - solvent extraction – crystallisation plant which is located on the Tartana mining leases. The refurbishment and commissioning of this plant is now completed and the company is producing copper sulphate pentahydrate which is sold to offtaker, Kanins International. Copper sulphate is priced on a premium plus percentage of the LME copper price and provides investors with leverage to anticipate increasing copper prices.
The company, formerly known as R3D Resources, changed its name to Tartana Minerals in April 2024. Tartana Minerals is based in Sydney, Australia.
Tartana Minerals has reported the following resources:
- 45,000 tonnes of contained copper at 0.45 percent copper in combined inferred and indicated resources in the Tartana open pit and northern oxide zone
- 39,000 tonnes of contained zinc at 5.29 percent zinc in inferred resources in the Queen Grade project, also located on the Tartana mining leases, and
- 415,000 oz contained gold at 0.34 g/t in inferred resources at Mountain Maid – subject to a mining lease application.
These copper, zinc and gold resources remain open at depth and along strike and the company has designed drilling programs to expand these resources. In particular, the copper mineralisation and potentially the gold mineralisation have scope to be upgraded through ore sorting.
However, the refurbished heap leach – solvent extraction – crystallisation plant utilises existing copper in the ponds and the heaps and these copper sources will be replenished when we commence mining from the open pit.
Copper sulphate contains 25 percent copper metal and payment is based on the LME copper price for the preceding month plus a premium. It is one of the few forms of saleable copper where the copper content receives the full LME price.

Tartana Minerals completed the acquisition of Queensland Strategic Metals with drilling planned to commence in 2025 that includes the Daisy Bell tin-tungsten project where historical drilling and our mapping have identified a potentially tin-rich zone.
Company Highlights
- Tartana Minerals is producing copper sulphate pentahydrate from its heap leach – solvent extraction – crystallisation plant in Chillagoe with a 100 percent offtake agreement with Kanins International.
- Copper sulphate is priced at a premium plus a percentage of the LME copper price, providing exposure to the booming copper market
- With copper, zinc and gold resources in separate projects and all within granted or soon to be granted mining leases, the company is investigating processing options which can potentially utilise available infrastructure.
- Near-term catalysts include targeted drilling programs to increase the JORC resource and expand on metallurgical test work, increasing the resource grade and estimate
- With the copper sulphate plant fully commissioned and in production, the company is now accelerating its exploration activities. The company has a range of prospects from advanced brownfields projects near existing historical mines to many prospects containing ‘ore grade’ surface mineralisation which have not been tested at depth.
- The company’s exploration portfolio includes the Beefwood/Bulimba, Bellevue, Dimbulah, Cardross and Maid projects. The exploration team is focused on target generation, particularly with the addition of critical minerals within its existing tenure and elsewhere.
Exploration
The Chillagoe region of Far North Queensland is highly prospective with the discovery and development of a number of key projects over the last few decades including Red Dome (2.5 Moz gold), Mungana (1.2 Moz gold), and King Vol (250 kt zinc). These deposits occur along the Palmerville Fault in a similar location to the Tartana Mining leases.
The mining leases at Tartana contain copper, zinc and gold mineralisation but the company also has significant projects which are both east and west of the Palmerville Fault. In the west it has the Cardross and Mountain Maid copper-gold projects and further north it has the Beefwood project. Mountain Maid has gold resources mentioned above and which are open to the south and at depth while the company is finalising a maiden copper resource for the Cardross project.
The Beefwood project comprises a buried geophysical target and surface sampling has recovered samples grading up to 180 g/t gold with no apparent source. Drilling is planned to test this target in the current dry season.
In the east of the Palmerville Fault, the company has the Bellevue/Dry River project, the OK South project and the Dimbulah Porphyry project, all copper projects with historic copper mines and prospects. Like many parts of Far North Queensland, historical exploration has not been systematic and thorough despite many promising expressions of surface mineralisation.
At the Nightflower project, Tartana has upgraded its exploration target after reviewing its earlier estimation, in light of the recent increases in the antimony price. Nightflower is a high-grade silver-lead deposit with previously overlooked significant antimony credits. Nightflower exploration target includes 2.75 Mt @ 364 g/t silver equivalent for 32 Moz silver equivalent to 5.36 Mt @ 270 g/t silver equivalent for 47 Moz silver equivalent (the exploration target is conceptual in nature only and there is no guarantee that further exploration will define a resource). Drilling is now being planned to test the target and upgrade previously identified mineralisation to JORC 2012 reporting standards.
Tartana’s exploration team comprises experienced exploration geologists with supporting cash flow from their copper production, they expect to be able to drill the most promising targets in the short term.
Strong Macroeconomic Environment for Copper
Overall, the macroeconomic environment for copper remains strong. The LME three-month copper price hit US$5.24/lb on May 17, the highest since March 7, 2022, driven by a weaker US dollar, Chinese property stimulus measures, and a short squeeze on the Chicago Mercantile Exchange futures market.
In the near-to-mid term, China’s demand for refined copper is expected to grow, due to better-than-expected performances from key consumer segments, including the power grid, solar installations and electric vehicle and air conditioning appliance sales. On the supply side, the copper concentrate market is expected to remain in a significant deficit due to the estimated delay in the Cobre Panama mine restart but will be partially offset by the higher projected production from smelters in China. As a result, we see further demand growth and supply tightening for the copper market as positive for base metal equities to maintain significant leverage to increase prices.
