Lincoln Minerals Unveils High-Priority Copper Targets at Minbrie Ahead of Drilling
Lincoln Minerals has identified multiple high-priority drill targets at its Minbrie Copper-Base Metals Project in South Australia, with drilling approvals advancing for a campaign planned in the second half of 2025.
- Multiple high-priority copper-base metals drill targets defined via 3D geological modelling
- Historic core re-logging and 344 new assays confirm high-grade sulphide mineralisation
- Drilling approvals progressing, with first phase drilling planned for H2 2025
- Targets include oxide/supergene and fresh sulphide zones within a multiphase sulphide system
- Minbrie project located in the highly prospective Gawler Craton, near major mineral deposits
Strategic Advances at Minbrie
Lincoln Minerals Limited (ASX:LML) has taken a significant step forward in its exploration efforts at the Minbrie Copper-Base Metals Project on South Australia's Eyre Peninsula. The company announced the identification of multiple high-priority drill targets, underpinned by a comprehensive review of historic drilling data, new assay results, and advanced 3D geological modelling.
These developments come after Lincoln's rigorous reassessment throughout 2025, which included re-logging over 1,700 metres of historic diamond core and submitting 344 new laboratory assays. This work has notably de-risked the project by confirming zones of high-grade mineralisation and refining the geological understanding of the mineral system.
Targeting a Complex Mineral System
The Minbrie project lies within the Gawler Craton, a geological region renowned for hosting some of South Australia's most significant mineral deposits, including Olympic Dam and Carrapateena. Lincoln's exploration has revealed a multiphase sulphide system with four distinct mineralisation events, suggesting a complex and long-lived hydrothermal system with strong potential for copper and base metals.
Three structurally controlled trap zones have been delineated in the Northern Corridor of the project area. These zones are associated with key geological features such as the contact between magnetite iron formations and dolomite units, weathering fronts conducive to oxide enrichment, and fault intersections that may act as conduits for mineralising fluids.
Drill Targets and Upcoming Campaign
Among the standout targets are the BUDD192 zone, which previously returned a significant intercept of 29.5 metres grading 0.8% copper, 7.5% lead, 1.9% zinc, and 9 grams per tonne silver, and the BURCD030 extension, where portable XRF readings indicated copper concentrations exceeding 3%. Additional southern step-out targets have been identified, showing favourable geology and mineralisation indicators.
Lincoln is advancing drilling approvals, with regulatory submissions well underway and no anticipated delays. The company plans to commence drilling in the second half of 2025, initially focusing on Trap Zones 1 and 2 to test both oxide/supergene and fresh sulphide mineralisation.
Positioning for Future Growth
CEO Jonathon Trewartha highlighted the importance of the recent technical work in reducing exploration risk and sharpening targeting strategies. He emphasized the project's strategic location within a world-class mineral province and the potential for Minbrie to emerge as a significant copper and base metals discovery.
Lincoln Minerals continues to build on its portfolio of critical minerals projects in South Australia, aligning with global trends towards electrification and decarbonisation. The Minbrie project, with its promising exploration results and imminent drilling campaign, is a key asset in this strategy.
Bottom Line?
With drilling approvals imminent, Lincoln Minerals is poised to unlock Minbrie’s copper potential, setting the stage for a pivotal exploration phase.
Questions in the middle?
- Will the upcoming drilling confirm continuity and scale of the high-grade mineralisation at Minbrie?
- How might the complex multiphase sulphide system influence future resource estimation and mining methods?
- What are the potential timelines and pathways for advancing Minbrie towards development following drilling?
