Restarting Leigh Creek Copper Mine

The Leigh Creek Copper Mine (LCCM) is a brownfield mining operation located in the North Flinders Ranges of South Australia, approximately 500 km north of Adelaide. The project focuses on restarting copper production from existing oxide deposits, including Paltridge North, Lynda, and Lorna Doone, which collectively hold a JORC-compliant resource. Utilizing established infrastructure such as the Mountain of Light processing plant, sealed roads, and airport access, the initiative employs heap leach and Kennecott cone processing methods to facilitate a resumption of operations .

The LCCM project emphasizes a staged approach to development, beginning with low-cost oxide copper extraction to generate early cash flows, while planning for potential expansion into deeper sulphide resources.

  • The Leigh Creek Copper Mine (LCCM) employs a heap leach process to extract copper, utilizing existing pads and Kennecott cones to produce +70% Cu cement. The refurbished Mountain of Light plant, with filter press, genset, and lab, is production-ready, enabling efficient, low-cost copper recovery.

  • The Leigh Creek Copper Mine (LCCM) region, in South Australia's Northern Flinders Ranges 500 km north of Adelaide, hosts significant oxide copper resources. A JORC-compliant estimate totals 3.6 million tonnes at 0.7% Cu, containing 24,900 tonnes across brownfield deposits like Lynda, Lorna Doone, Mountain of Light, and Mount Coffin on active mining leases.

  • The Northern Flinders Ranges region in South Australia features a geological setting of sedimentary and volcanic rocks hosting copper deposits. Oxide copper mineralization, including malachite, is prominent in historic open-cut sites. Underlying sulphide deposits offer significant exploration potential for future copper discoveries.

Cuprum’s Objectives

Cuprum Metals is laser-focused on reviving and expanding copper production in South Australia's copper-rich Northern Flinders Ranges. Our immediate objective: swiftly acquire the Leigh Creek Copper Mine (LCCM), a brownfield asset with proven JORC oxide resources, and restart operations from full funding via low-capex heap leaching.

Cuprum plans to ramp up in the near term, then scale to nameplate capacity, leveraging the refurbished Mountain of Light plant — complete with filter presses, gensets, and labs — for efficient, low-cost recovery and an existing offtake agreement.
