Mineral Resources & Planned Mining Development
Tennora Resources is progressing the next phase of mining development across its mineral assets in Tennant Creek, Northern Territory. Building on established mineral resources, historical geological studies and existing mining infrastructure, the company is advancing mine planning, technical evaluations and the relevant regulatory approval processes to support the development of its gold, copper and cobalt resources alongside its existing magnetite-rich iron ore operations.
Our strategy combines established magnetite-rich iron ore recovery operations with the planned development of gold, copper, cobalt and bismuth resources, building on the region's historically significant mineral system and advancing a diversified approach to mining and mineral recovery.
Mineral Portfolio
Mineral
Reported Grade
Mineral Significance and Planned Mining
Iron Ore (Magnetite)
41-50% magnetite
Magnetite-rich resources form the foundation of Tennora's current recovery operations, with opportunities for further processing, beneficiation and long-term commercial development
Gold (Au)
2.36–7.13 g/t
3.33%–5.20%
Copper (Cu)
Resource estimates demonstrate significant gold mineralisation, which supports further recovery and future mining development..
Underground resource estimates indicate copper-rich mineralisation, supporting future exploration and resource development.
Bismuth (Bi)
Cobalt (Co)
0.10% Co (historical inferred estimate)
Cobalt represents an additional critical-mineral opportunity associated with the project's polymetallic mineralisation. Geological assessments identified cobalt within underground resources, providing a basis for further investigation of its distribution, concentration, metallurgical recovery and commercial potential
0.20% Bi (historical inferred estimate)
Bismuth is an important component of Tennora's polymetallic mineral system, with approximately 7,350 tonnes historically produced from the mining assets. Tennora is incorporating bismuth into its broader mineral development strategy, with ongoing mine planning and technical evaluations considering its potential recovery alongside gold, copper and cobalt. The company is assessing opportunities to maximise the value of its multi-commodity resources through integrated mining and mineral recovery processes.
