Restarting Leigh Creek Copper Mine

A Clear Path to Cashflow

Cuprum Metals, an emerging copper producer, is revitalizing the Leigh Creek Copper Mine (LCCM) in South Australia’s copper-rich Adelaide Geosyncline. LCCM features JORC 2012-compliant oxide resources across multiple deposits, supplemented by pre-2012 JORC resources that offer additional upside. We aim to ship our first product within 6-8 months based on our existing offtake agreement for rapid cash generation. LCCM aims to scale operations to nameplate volumes.

With approvals in place and robust copper prices, Cuprum is positioned for sustainable growth. The Leigh Creek mine is the centerpiece of Cuprum’s regional consolidation strategy. The Flinders region has numerous oxide targets along with strong sulphide potential. We are now identifying and acquiring regional exploration and mining leases. The region is host to major deposits such as Olympic Dam and Carrapateena.

  • 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 Pty Ltd 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 within 6-8 months via low-capex heap leaching.

We'll ramp up to 100 tonnes of contained copper per month 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.

Backed by exclusive agreements and project finance discussions, we project robust free cash flows over an initial 9-year mine life, with off-take secured via Adchem. But we're not stopping there. Cuprum aims to become the regional consolidator, acquiring nearby deposits, exploring sulphide potential beneath oxides, and enabling toll treating to extend operations and unlock untapped value in this geologically promising area.

Join us in transforming legacy assets into a dynamic copper powerhouse.
