Lincoln Minerals identifies multiple high-priority copper-base metal drill zones
Re-logged historical core and updated assays enhance geological understanding
Approvals underway ahead of drilling at the Minbrie Project in South Australia
Lincoln Minerals Ltd (ASX:LML), listed on the All Ordinaries, has unveiled a series of high-priority drill targets at its Minbrie Copper and Base Metals Project, located on South Australia's Eyre Peninsula. The company’s progress follows extensive technical reassessment and 3D geological modelling of its northern tenements, as part of an ongoing copper exploration strategy within the Gawler Craton.
The Minbrie Project forms part of a broader ambition to uncover mineral systems hosted beneath the footwall sequence of the Bungalow Magnetite deposit. This region remains under-explored despite proximity to prominent Australian copper-gold assets.
Detailed Geological Review Drives New Exploration Zones
To refine targeting, Lincoln Minerals undertook a re-logging program involving over a thousand metres of historical core samples. Fresh assays were also submitted to support structural and geochemical analysis. This data revealed features consistent with known sulphide mineralisation and enabled the identification of Trap Zones 1 and 2 as initial drilling priorities.
The Northern Zone was flagged for immediate follow-up, with selection criteria based on structural geometry, mineralogy, geochemical footprint, and proximity to established mineralised corridors. The company noted that the historical drilling and recent technical work confirmed multiple sulphide-bearing intervals suitable for further assessment.
Drilling Approvals Progressing as Campaign Nears
Approvals for drilling activities are currently in progress, with preparations reportedly in advanced stages. Lincoln Minerals expects to commence its drill campaign during the second half of the upcoming year, focusing first on the newly prioritised trap zones.
The company’s leadership stated that its updated modelling and the discovery of a multi-phase sulphide system will provide a clear roadmap to explore both oxide and sulphide components of the Minbrie system. This strategic approach is part of an expanded effort to unlock critical mineral resources across South Australia’s copper-rich craton.
Regional and Project Context Supporting Development
The Minbrie Project is situated within a seven-kilometre strike length of mineralisation and benefits from proximity to infrastructure and established mining operations. The Gawler Craton has long been recognised for its endowment of iron oxide copper-gold deposits, with notable sites such as Olympic Dam, Prominent Hill, and Carrapateena highlighting the area’s broader geological appeal.
Lincoln Minerals is positioning the Minbrie asset as a core component of its portfolio of critical mineral projects. Throughout the current calendar year, the company has applied contemporary exploration techniques to revisit and enhance the existing project dataset, creating a detailed platform for planned field activities.
Engagement at Upcoming Mining Event
The company will also participate in the Noosa Mining Investor Conference, held in July, showcasing its South Australian exploration initiatives. The event presents an opportunity to share project updates, including progress on drilling approvals and geological interpretations related to Minbrie and other regional assets.
