Company Highlights
True North Copper is preparing to become Australia’s next copper producer.
True North Copper’s two principal assets are located in northwest Queensland, Australia – a Tier 1 Jurisdiction:
- Cloncurry Copper Project (CCP) – IOCG and ISCG copper-gold deposits proposed for open pit mining operations, with extensive surrounding exploration tenure.
- Mt Oxide Project (Mt Oxide) – IOCG high-grade, globally significant, copper-cobalt-silver deposit subject to re- optimisation studies, and exploration in surrounding tenure.
Cloncurry Copper Project (CCP)
- Mining restart study confirms positive CCP project economics – AU$367 million with free cash flow of AU$111 million, and a pre-tax NPV10 of AU$88 million over a 4.6 year mine life, at US$8,500 per ton copper price and US$1,850 per ounce gold price (0.7 AU$:USD exchange rate).
- Wallace North Mine preparation and mobilisation. Wallace North is scheduled as the first open pit (one of four – Wallace North, Great Australia Mine [GAM], Taipan and Orphan Shear) to be mined as part of the mining restart at the CCP.
- Mining ramp-up will initially build ore stockpiles, with mining expected to start Q4 FY24(AUS). Oxide copper-gold ore will be transported by road train to the Cloncurry Operations heap leach. Sulphide ore will be transported to a nearby concentrator for toll treatment under TNC’s toll-milling agreement with Glencore.
- CCP’s total reserves increased. TNC’s Cloncurry Copper Project (CCP) total reserves currently include 4.7Mt probable ore reserves grading 0.80 percent copper and 0.13g/t gold, containing 37.5 kiloton of copper and 20.0koz of gold.

Projects
Cloncurry Copper Project
Our Cloncurry copper project (CCP) hosts iron oxide copper-gold (IOCG) and iron-sulphide-copper-gold (ISCG) deposits with extensive surrounding exploration tenure. It is built on a strong economic basis and low-risk cost structure.
The CCP currently incorporates two reserves where mining will commence including – the Wallace North maiden resource and the Great Australia mine reserve (GAM):
- GAM includes GAM, Orphan Shear and Taipan deposits) totalling 4.7Mt grading 0.80 percent copper and 0.13g/t gold containing 37.5kt of copper and 20 koz of gold – upgrade to be announced mid-2024.
- Wallace North ore reserve totals 0.7Mt (probable) grading 1.01 percent copper and 0.46g/t gold for 6.8kt copper and 10 koz gold.
TNC’s CCP expansion is ongoing with exploration progressing and advanced projects in strategic locations surrounding the existing CCP operation, promising long-term growth prospects.
Our strategic partnerships, including a binding offtake and toll-milling agreements with Glencore International AG, supported by debt funding secured with Nebari, underscore our operational readiness and position TNC to capitalise on an extremely favourable copper market.
Mining operations will kick-off at the Wallace North open cut pit, targeting higher-grade ores (~1 percent copper) from surface mining. Ore will undergo primary crushing at the Cloncurry operations hub and the toll treatment facility, located within a 40km radius, with a predominant focus on sulphide ores.
All necessary permits for mining are secured across the CCP, bolstered by an established environmental monitoring network with a robust historical database.
TNC’s operational strategy involves a phased approach to mine development, with plans to commence mining operations in 2024 and manage capacity ramp-up throughout 2025.
Cloncurry Operations Hub
The Cloncurry operations hub is strategically located to the CCP’s four open pit deposits including: Great Australia, Orphan Shear, Taipan and Wallace North.
The COH is located 2 kilometres from the township of Cloncurry and provides essential infrastructure, technical systems and support to all of TNC’s project operations. An active oxide heap leach and solvent extraction (SX) processing plant, mine buildings, site administration facilities, workshops, open pit mine facilities, onsite explosive magazines, site storage, water management systems and existing site power supply are located at the COH.
