True North Copper’s Wynberg Study Eyes $87M Cash Flow From Two-Year Gold-Copper Mine
Wynberg Scoping Study adds a high-value gold-copper leg to the Cloncurry story
True North Copper has released the Wynberg Gold-Copper Scoping Study, demonstrating a low-capital, near-term development opportunity that strengthens the broader Cloncurry Copper Project. The study outlines a Production Target of 0.87 Mt for 53 koz AuEq (47 koz Au + 2.1 kt Cu), based exclusively on Measured and Indicated Resources, with pre-tax cash flow potential ranging from $53M to $87M across three development scenarios. Key de-risking factors include an existing Mining Lease (ML 100111), environmental approvals in place, and settled land access agreements. This is a scoping-level study with cost estimates accurate to +/-30-35%, and no Ore Reserve has been declared.
Highlights at a glance:
- Production Target: 0.87 Mt @ 1.67 g/t Au and 0.24% Cu (Measured and Indicated only)
- Pre-tax cash flow: $53M–$87M across three scenarios
- Mining approvals: Existing Mining Lease and environmental approvals in place
- Development pathways: Standalone, toll treatment, or integration with the Cloncurry Copper Project
- Funding requirement: $23M–$38M pre-production capital (scenario-dependent, not secured)

Breaking down the numbers — three pathways, one deposit
The study’s core strength is optionality — multiple development pathways rather than a single route. Each scenario differs in processing method, metal recovery, and capital intensity.
The economics by scenario
| Scenario | Processing route | AuEq produced | Pre-tax cash flow | Funding req. |
|---|---|---|---|---|
| A | Gravity + CIL (all) | 39.7 koz | $52.8M | ~$28M |
| B | Gravity/CIL oxide + Flotation | 45.1 koz | $86.8M | ~$23M |
| C | Heap leach oxide + Flotation | 40.2 koz | $59.4M | ~$38M |
Scenario B delivers the strongest economics, with an 88% cash flow margin and the lowest funding requirement. It combines gravity/CIL processing for oxide mineralisation with flotation for transitional and fresh material, maximising metal recovery while minimising upfront capital.
What underpins it
The deposit is planned as two shallow open pits (East and West, 500m apart) supporting a 2-year mining campaign. The strip ratio is 8.4:1. The Production Target is 64% Measured and 36% Indicated, with no Inferred Resource included — a confidence positive signalling higher geological certainty than many early-stage studies.
What is a Scoping Study — and why “optionality” matters here
A Scoping Study is an early-stage assessment testing whether a project is worth advancing to Pre-Feasibility. It operates with cost estimates accurate to +/-30-35% and precedes the declaration of an Ore Reserve. The study does not confirm economic viability or provide certainty that outcomes will be realised — it establishes whether further work is justified.
Why multiple development pathways matter to investors: Flexibility to align with commodity prices, available regional processing infrastructure, and capital constraints reduces single-point risk. If one pathway faces permitting delays or unfavourable pricing, the company can pivot to an alternative route without restarting the study.
Because True North Copper can process at nearby facilities (Lorena, Ernest Henry, Eloise, Rocklands, or its own Mt Norma), it avoids heavy upfront plant capital. Toll treatment — processing ore at a third party’s existing plant for a fee — is a lower-capital pathway that allows the company to monetise the resource without building its own mill.
Available pathway options:
- Standalone gravity/CIL processing (all material)
- Toll treatment at regional flotation plants (sulphide material)
- Integration with the Cloncurry Copper Project (future optionality)
Where Wynberg fits — strengthening the Cloncurry Copper Project
Wynberg sits within the “Develop” platform alongside the Cloncurry Copper Project, targeting near-term cash flow. The deposit is located approximately 30 km by road from the Great Australia Mine, within an established mining district with skilled local workforce at Cloncurry. Existing infrastructure includes sealed highway access, with only 3.5 km of unsealed haul road requiring construction.
Exploration upside remains. Mineralisation is open along strike and at depth. Regional targets including Burnt Ute, Birdvale, and Black Siltstone offer further potential, though these are early-stage prospects and not yet resources. Burnt Ute, for example, has a 1.7 km long copper-gold anomaly at surface, with rock chip samples returning up to 25% Cu and 11.4 g/t Au. Recent geophysics identified three large conductive zones beneath the prospect extending beyond 600 m depth.
Andrew Mooney, Managing Director
“…Wynberg Gold-Copper adds another low-capital development opportunity with multiple pathways to unlock value, including standalone development, regional processing and integration with the Cloncurry Copper Project. Together with Wallace North and Mongoose-Taipan, Wynberg highlights the broader opportunity to optimise and enhance the Cloncurry Copper Project. With the CCP Pre-Feasibility Study on track for completion in late 2026 and ongoing exploration results expected from Mt Oxide over the coming months, we are well positioned to continue building long-term value for our shareholders.”

What comes next — the 2026-2027 roadmap
Key milestones ahead:
- Mt Oxide Project — continued Aquila drilling and regional exploration results through remainder of 2026.
- Cloncurry Copper Project — Pre-Feasibility Study and potential Ore Reserve targeted for late 2026.
- Wynberg — further metallurgical (notably flotation validation), engineering and optimisation studies through 2026-2027 to refine the preferred pathway.
- Portfolio optimisation — advancing Wallace North, Mongoose-Taipan and Wynberg to expand the Cloncurry Copper Project beyond the initial Pre-Feasibility Study.
The $23M-$38M pre-production capital will be required (debt/equity), not yet secured. The company has a track record of raising capital and relevant development experience in the Cloncurry region, but there is no certainty funding will be available when needed or on terms that do not dilute existing shareholders. As the project advances through metallurgical test work and engineering studies, investors will gain clarity on the preferred development pathway and timing of a potential construction decision.
