Lincoln Minerals Sets Stage for Copper Drilling at Minbrie with Strong Graphite Returns

A Strategic Critical Minerals Portfolio

Lincoln Minerals Limited is advancing its diversified portfolio of critical mineral projects in South Australia’s Gawler Craton, a region renowned for its rich endowment of copper, uranium, graphite, and iron. The company’s latest update highlights the Minbrie copper-base metals project, where a continuous 7-kilometre strike of mineralisation has been identified, setting the stage for imminent drilling activities pending regulatory approvals.

Alongside Minbrie, Lincoln is progressing its Kookaburra Graphite Project, which boasts compelling economics with a pre-tax net present value of A$114 million and an internal rate of return of 41%. The Green Iron Project further complements the portfolio with a substantial 1.2 billion tonne resource of high-purity iron, strategically located near key infrastructure that promises to reduce capital expenditure and accelerate development timelines.

Minbrie – Unlocking Copper-Base Metals Potential

The Minbrie Project stands out as a potentially significant copper-base metals discovery. Situated in the Gawler Craton, a globally recognised mining jurisdiction, Minbrie features shallow mineralisation zones less than 200 metres deep, suitable for open-pit mining. Historic drilling, including the notable BUDD192 hole which intersected 29.5 metres grading 0.8% copper, 7.5% lead, 1.9% zinc, and 9 grams per tonne silver, underscores the project’s promise.

Lincoln’s reinterpretation of legacy data has revealed that previous exploration largely overlooked the copper and base metal potential beneath iron ore targets. With approvals for drilling anticipated within two months, the company plans to test multiple target zones in the northern corridor, aiming to define the scale and grade continuity of this mineralised system.

Graphite and Iron – Strong Fundamentals and Strategic Partnerships

The Kookaburra Graphite Project is positioned for near-term development, benefiting from an existing mining lease and proximity to infrastructure such as power, water, and port facilities. Its low start-up capital requirement of A$29 million and robust cash flow projections make it a standout asset in Australia’s growing graphite sector.

Similarly, the Green Iron Project offers a high-purity iron resource with the potential to produce direct reduction iron (DRI), a material increasingly in demand for electric arc furnace steelmaking. The project’s location near power, water, and multiple port options, including the approved Cape Hardy Port, aligns well with South Australia’s green steel ambitions and government support.

Uranium Exploration in an Emerging Province

Lincoln’s Eyre Uranium Portfolio targets an emerging uranium province on the Eyre Peninsula, with multiple drill-ready targets identified. Historic intercepts of up to 570 parts per million uranium and recent surface sampling confirm the prospectivity of this portfolio. The company is planning further drilling and geochemical surveys to advance these targets, capitalising on South Australia’s status as a global uranium resource hub.

Infrastructure and Jurisdictional Advantages

All of Lincoln’s projects benefit from proximity to existing infrastructure, including grid power, water, road access, and ports. This infrastructure advantage is critical in lowering capital costs and expediting project development. The political stability of South Australia and its strong trade links to Asia and beyond further enhance the attractiveness of Lincoln’s portfolio.

With copper prices near record highs and demand forecast to rise sharply due to electric vehicles and renewable energy growth, Lincoln Minerals is well positioned to capitalise on the structural supply gap. The company’s multi-commodity approach across copper, graphite, uranium, and iron offers diversified exposure to critical minerals essential for the energy transition.
