Lincoln Minerals Limited’s latest re-logging campaign has unveiled promising copper-base metals targets. Advanced pXRF analysis of legacy drill data identified multiple mineralised zones, with plans for accelerated drill testing in H2 2025. An investor webinar today will shed further light on their next exploration phase.
Lincoln Minerals Limited has provided an extensive update on its re-logging and assaying program at the 100%-owned Minbrie Copper-Base Metals Project near Cowell on South Australia’s Eyre Peninsula. The company’s work has focused on re-evaluating legacy drill holes from earlier magnetite exploration, with 28 historical holes re-logged over 1,775 metres of core. In this campaign, over 620 portable XRF readings were collected, and 224 core intervals have been earmarked for laboratory assay. These efforts have unveiled multiple previously unrecognised sulphide intercepts and have revealed a complex system with four distinct generations of mineralisation—highlighting a dynamic, long-lived hydrothermal system with clear zonation patterns.
Technical highlights include a strong geological correlation between discovery hole BUDD1921 and nearby hole BURCD030. Detailed relogging and pXRF analysis identified bornite in a vein within the Katunga Dolomite just four metres from the end of BURCD030, registering copper readings of up to 3.03% at a downhole depth of 274 metres. The identification of multiple prospective zones across a 7-kilometre strike of sulphide-bearing stratigraphy underpins the company’s strategy of leveraging historical data with modern technology, rapidly targeting key mineralised intervals without the immediate need for new drilling.
Looking ahead, Lincoln Minerals Limited plans to finalise drill targets by the end of June 2025, with further drilling scheduled to commence in the second half of the year. In the coming weeks, laboratory assay results are expected to be released progressively, alongside the completion of an initial 3D geological model that will further refine drill targeting. The company is hosting an investor webinar today at 1:30pm AEST where the CEO and technical team will discuss these latest findings and outline the forward-looking exploration strategy.
From a market sentiment perspective, the technical indicators are broadly positive. The re-logging program, the identification of multiple sulphide events, and the promising copper assay results have ignited enthusiasm among investors given the potential for unlocking significant copper and base metal value. On the other hand, the reliance on portable XRF readings—which only provide approximate elemental concentrations—and pending laboratory assays introduce a measure of uncertainty typical for early-stage exploration. While the upcoming drill program and assay milestones are likely to bolster confidence, investors are advised to remain cautious as the project’s results are still being validated by further testing and analysis.
