Latest Developments

Metallurgical Results at Wallace North

On 20 October 2026, True North Copper said flotation testing at Wallace North averaged about 89% copper recovery at a concentrate grade of about 20% copper. According to the announcement, three composites were tested, with recoveries ranging from 83.4% to 95.8% and an average head grade of 1.86% copper. The company described the metallurgical test program as nearing completion.

Pulp leach testing on oxide and transitional material returned about 99% acid-leachable copper from Mongoose-Taipan, while Orphan Shear returned a range of 44% to 98%, according to the company.

Mineral Resource Growth

In the same 20 October 2026 announcement, True North Copper said the CCP contained copper-equivalent Mineral Resource increased 62% during 2026, from 126 kt to 204 kt of copper equivalent. The company attributed the change to drilling, the consolidation of Mongoose-Taipan and updated Resource estimates, and noted the addition of Wynberg, which it described as a defined gold-copper component. It said Wallace North Resource grades are around 4% copper equivalent.

PFS Progress and Regional Context

The company said on 20 October 2026 that pit optimisation, mine design and scheduling are well advanced, supported by updated contractor pricing and financial evaluation. The PFS is evaluating regional processing Options across Mt Isa, Rocklands, Ernest Henry and Eloise. The announcement also referred to regional acquisitions in the North West Minerals Province, including Evolution Mining's Acquisition of Carnaby Resources (A$213 million).

Managing Director Andrew Mooney said the company's focus is on delivering a right-sized, capital-efficient PFS in late 2026 while progressing further Resource growth and optimisation work through 2027.

About True North Copper Ltd

True North Copper Ltd is an ASX-listed company headquartered at the Great Australia Mine site near Cloncurry, Queensland. Its flagship is the Cloncurry Copper Project, which comprises several copper-gold deposits, including Wallace North, Mongoose-Taipan, Wynberg, Orphan Shear and the Great Australia Mine area. According to the company, much of the Mineral Resource is located within existing Mining Leases, although Mongoose is subject to a Mining Lease Application, and the project sits near regional processing and smelting facilities. The company has said potential production could begin from late 2027 to early 2028, supported by toll-processing agreements.

Related Sector Context

True North Copper operates in the copper and copper-gold segment of the ASX-listed resources sector, where companies at the study stage typically report drilling, metallurgical and mine planning outcomes ahead of development decisions. The Cloncurry region of north-west Queensland hosts established mining and processing operations, and the company's announcement noted that ore Supply is being secured by operators to Fill available processing capacity. On the day, the S&P/ASX 200 was at 8,760.50, down 0.37%, so the move in True North Copper was considerably larger than that of the broader market benchmark.

Risks to Weigh In

  • The Cloncurry Copper Project remains at the pre-feasibility stage, and the company has not yet declared an Ore Reserve.
  • Mongoose is the subject of a Mining Lease Application, and environmental approvals are still being advanced, according to the company.
  • Production timing depends on toll-processing agreements that the company said are still to be progressed.
  • Oxide leach recoveries at Orphan Shear varied widely in testing, from 44% to 98%, which the company said it considers manageable through blending and campaign operations.
  • Copper-equivalent estimates rely on a stated copper price assumption and metallurgical recovery factors, so they are exposed to changes in those inputs.

Catalysts on Watch

  • Completion of the CCP PFS and a potential maiden Ore Reserve, both targeted by the company for late 2026.
  • Near-mine and resource extension drilling at Wallace North, Mongoose-Taipan and the broader project from late 2026 into 2027.
  • Further metallurgical testing, including Wynberg gold-copper flotation, identified by the company for 2027.
  • Progress on environmental studies and approvals, including the Mongoose Mining Lease grant.
  • Progress on potential toll-processing agreements.

Where Things Stand

True North Copper shares were trading at A$0.20, down 16.67%, during the 23 October 2026 trading session, against a 0.37% decline in the S&P/ASX 200. The company's most recent announcement, dated 20 October 2026, reported an average copper recovery of about 89% at Wallace North, a 62% increase in contained copper-equivalent Resources during 2026 and a PFS that the company said is on track for late 2026. Further disclosures on the PFS and drilling are expected to come from the company itself.
