Highlights

  • Progressive Rehabilitation and Closure Plan approvals have been secured across all five existing Mining areas at the Cloncurry Copper Project.
  • The Mongoose Mining Lease application has been lodged and is progressing toward assessment, supporting the expanded mineral resource and potential open pit.
  • Existing Mining Leases at the Cloncurry Copper Project remain in good standing, with renewals progressing where required.
  • The Pre-Feasibility Study remains targeted for completion in the fourth quarter of 2026, assessing a capital-efficient development pathway for the project.

True North Copper Limited (ASX:TNC) has announced further progress on key environmental approvals for its Cloncurry Copper Project (CCP) in Queensland. The company has secured transitional Progressive Rehabilitation and Closure Plan (PRCP) approvals across all five existing mining areas, covering the Great Australia Mine, Taipan, Orphan Shear, Wynberg and Wallace North sites. These approvals strengthen the regulatory foundation for future mining operations and reduce development risk for the project.

The approvals build on the Cloncurry Copper Project's existing Mining Leases and established infrastructure, adding an important layer of regulatory confidence ahead of the Pre-Feasibility Study completion targeted for the fourth quarter of 2026. The company notes that it has established a constructive working relationship with Queensland's Department of Environment, Tourism, Science and Innovation through the approvals process.

Environmental Milestones and Regulatory Progress

In addition to the PRCP approvals across the five active mining areas, True North Copper has lodged a Mining Lease application for the Mongoose deposit, which is progressing toward formal assessment. The Mongoose application is designed to support the expanded Mineral Resource at that deposit and the potential development of an open pit. Future development approvals for larger, right-sized open pits are being targeted for the third and fourth quarters of 2027, subject to completion of the Pre-Feasibility Study and updated mine designs.

The PFS is currently assessing larger open pit configurations intended to support a more capital-efficient development plan for the Cloncurry Copper Project. The approvals secured to date, combined with the existing Mining Leases, provide a solid regulatory framework for progressing these updated mine designs through the next round of assessments.

Project Background and Resource Base

The Cloncurry Copper Project hosts a contained Mineral Resource of 204,000 tonnes of copper equivalent following a 62% increase in contained copper equivalent during 2026. The resource spans multiple deposits including Wallace North, Mongoose-Taipan, Great Australia, Orphan Shear and Wynberg, each with differing characteristics in terms of ore type, grade and depth. The project benefits from proximity to regional processing capacity and established infrastructure, which management views as providing flexibility in how the project is ultimately developed.

True North Copper's broader portfolio includes the Mt Oxide copper-cobalt-silver resource in northwest Queensland, which is separately being developed as a potential stand-alone asset. The company's three-platform growth strategy encompasses resource development at Mt Oxide, near-term Revenue generation from Cloncurry, and ongoing discovery efforts at regional targets.

Development Timeline and Strategic Focus

The company's immediate priorities for the remainder of 2026 and into 2027 include finalising the Pre-Feasibility Study and targeting declaration of a potential Ore Reserve. Near-mine and resource extension drilling at Wallace North and the Mongoose-Taipan corridor is planned to support resource growth from late 2026 through 2027. Development optimisation work including metallurgical testing, mine planning and processing evaluation is also underway.

The Cloncurry Copper Project's attributes — multiple mining leases, established infrastructure, proximity to regional processing facilities and a growing resource base — position it as a relatively near-term development candidate within True North Copper's portfolio. The progression of environmental approvals alongside the Pre-Feasibility Study reflects a measured, parallel-track approach to reducing development risk and building a credible pathway to future production.

Key Insights

Securing PRCP approvals across all five existing mining areas at Cloncurry is a meaningful step in reducing Regulatory Risk for the project, providing a clearer pathway through Queensland's environmental assessment processes. The concurrent progress on the Mongoose Mining Lease application and the ongoing Pre-Feasibility Study reflect a disciplined approach to project advancement. With a 62% growth in contained copper equivalent in 2026 and a PFS completion targeted by year-end, the Cloncurry Copper Project is at an active development inflection point. The company's constructive engagement with Queensland regulators and the layered structure of the resource across multiple deposits give the project flexibility in terms of development sequencing. Near-term attention will focus on PFS completion and the first potential Ore Reserve declaration.
