Lincoln Minerals Limited’s updated re-assays at its Minbrie project confirmed robust copper, lead, and zinc grades. Systematic analysis of legacy drill core reinforces their geological model and suggests potential for district-scale mineralisation, fueling optimistic prospects for future assay results and exploration milestones.
Lincoln Minerals Limited has provided an update on its Minbrie Copper-Base Metal Project, confirming that a re-assay of discovery drillhole BUDD192 has verified historical high-grade intercepts. The re-assay, conducted on laboratory pulp samples from the 2012 analyses, recorded an interval of 12 meters at 1.4% copper, 12.4% zinc, 2.0% lead, and 13 grams per tonne silver starting at 139 meters. The company has clarified technical details in the updated announcement, including revisions to table numbering in the JORC Table 1 to clearly distinguish between portable XRF (pXRF) and laboratory analyses.
The firm is systematically re-evaluating 1,775 meters of legacy drill core from 28 historic drillholes, from which 620 pXRF readings have been gathered. This effort has helped identify 224 mineralised core intervals that have been selected for full laboratory analysis. Alongside the confirmed base metals, the pXRF surveys detected elevated levels of nickel, cobalt, and chromium, suggesting that there might be additional mafic or ultramafic intrusive influences worth further exploration. Lincoln Minerals expects further assay results in June, along with a final drill target selection later in the month, as part of a phased exploration program aimed at unlocking the full potential of a mineralised system that extends over a 7km strike.
Commenting on the results, the company’s CEO highlighted how these robust re-assay outcomes not only reaffirm the high-grade nature of the intercepts but also support a broader geological model that underpins the project’s extensive base metal system. An investor webinar recently held by the company provided additional context, outlining the promising prospects of re-labelling and re-assaying legacy core samples to rapidly and cost-effectively assess the opportunity presented by the Minbrie prospect.
Bullish sentiment is supported by the confirmation of historical high-grade readings and the systematic approach taken by Lincoln Minerals to comprehensively re-assay legacy drill core. The presence of additional target metals such as nickel, cobalt, and chromium adds to the project’s potential upside, and forthcoming assay results may further validate the significant breadth of the mineralised system over an extensive 7km strike.
On the other hand, bearish sentiment may stem from the inherent uncertainties associated with re-assaying legacy core material and the noted discrepancies in a small number of samples, which could reflect potential challenges in assay consistency. Additionally, the reliance on preliminary pXRF data—which, while useful for screening, does not replace full laboratory analyses—adds a layer of risk typically present in early-stage exploration ventures.
Overall, the updated technical information and strategic advances in the re-assay program position Lincoln Minerals Limited to potentially unlock greater value from a prospect that combines historical data with modern analytical methodologies.
