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 40-kilometre 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 mining activities commencing in 2024 and a planned ramp-up of production 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 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.
Cloncurry Copper Project – Project Economics
