Lincoln Minerals Scores 99.97% TGC Purity on Kookaburra Graphite

/in , /by

THE DRILL SERGEANT: Lincoln Minerals (ASX: LML) reported testwork results from the company’s Kookaburra graphite project (KGP) in South Australia.

Lincoln Minerals carried out test work related to its Battery Anode Material (BAM) Scoping Study, which it claims to have confirmed graphite purified from the KGP meets the stringent specifications required for use in lithium-ion battery (LiB) anodes.

Multiple test runs at two independent laboratories in Australia achieved purity levels above 99.95 per cent total graphitic carbon (TGC) – the industry benchmark for battery grade anode material.

The level of purification was achieved without the use of hydrofluoric acid (HF) – supporting a development path with safety and environmental benefits.

The company declared the results validate the quality of Kookaburra Graphite and provide a strong foundation for the ongoing BAM Scoping Study, which is focused on optimising the purification process, assessing key product characteristics, and exploring value-added opportunities to support a potential downstream processing facility in South Australia.

“We are extremely pleased with these outstanding initial results, particularly the achievement of battery grade purity levels without the use of hydrofluoric acid,” Lincoln Minerals CEO Jonathon Trewartha said in the company’s ASX announcement.

“This not only reduces the cost and complexity typically associated with anode material production but also increases major safety and environmental benefits – aligning strongly with modern ESG and clean-technology standards.

“These findings represent a major step forward in our Battery Anode Material Scoping Study and provide a strong technical foundation for the next phase of optimisation and product qualification.

“Importantly, they also build on the compelling economics outlined in our recently released Pre-Feasibility Study for the Kookaburra Graphite Project, which was based solely on direct concentrate sales.

“The ability to produce high-value anode material and other specialty graphite products has the potential to significantly enhance project returns and position Lincoln as a key player in the global graphite and battery materials supply chain.”

Lincoln Minerals Identifies Multiple Yallunda Project Uranium Anomalies

/in , /by

THE DRILL SERGEANT: Lincoln Minerals (ASX: LML) has detected multiple uranium anomalies at the company’s Yallunda uranium project located on the Eyre Peninsula, South Australia.

Lincoln Minerals recently carried out a sampling program across Exploration Tenements EL6648, EL5922, and EL6024 on the project that delivered promising assay results, highlighted by the uranium anomalies, which it considers to confirm the project’s potential for future discovery.

“Initial results from our assaying program at Yallunda are very encouraging, highlighting multiple uranium anomalies and confirming contact between the Moody Suite granites and the Hutchison Group metasediments,” Lincoln Minerals CEO Jonathon Trewartha said in the company’s ASX announcement.

“In particular, soil sample YD38 has highlighted a uranium-vanadium-molybdenum anomaly, and these are characteristic of redox-controlled uranium mineralisation, therefore providing a further follow up target.”

Soil sample YD38 exhibited notable multi-element anomalies, including:
• Uranium: 11.5ppm
• Vanadium: 380ppm
• Molybdenum: 36ppm

“We are planning a more comprehensive exploration program at Yallunda to commence in the second half of 2025 to map key lithological boundaries, undertake further geochemical sampling as well as geophysical surveys which will help us define potential mineralised zones,” Trewartha continued

“South Australia holds significant uranium resources and existing mining operations for uranium, and we look forward to providing updates on our work at Yallunda.”

Lincoln Minerals Re-assaying Historic Drill Core to Unlock Copper-Lead-Zinc Potential

/in , /by

THE DRILL SERGEANT: Lincoln Minerals (ASX: LML) is conducting a detailed assay program targeting base metal intervals in previously unassayed drill core at the company’s Minbrie copper and base metals project near Cowell, South Australia.

Lincoln Minerals took the initiative to re-assay drill core from an historic Centrex exploration program following recent discoveries of multiple sulphide-rich zones it considers to have enhanced the project’s scale potential.

Centrex’s 2011 exploration focused solely on magnetite, leaving base metal potential largely untested.

Lincoln is targeting untested base metal mineralisation from selection of historic drill core previously unassayed for copper, lead, zinc, silver and other payable metals at Minbrie.

By leveraging existing drill core, Lincoln is implementing a rapid, cost-effective exploration program.

“We have commenced assaying historic core samples from Minbrie for copper, lead, zinc, and silver,” Lincoln Minerals CEO Jonathon Trewartha said in the company’s ASX announcement.

“Over the coming months, I feel this site represents the most exciting exploration opportunity in South Australia.

“Our goal is not only to provide evidence of a major base metal discovery but also allow Lincoln to develop and undertake an exploration program.

“Success here will demonstrate that the southern Gawler Craton is a highly desirable address, complementing the northern portion, which hosts Olympic Dam, Prominent Hill and Carrapateena.

“Our initial discovery at Minbrie, highlighted by copper, lead, zinc and silver intercepted in discovery hole BUDD192, underscored the untapped potential of this project.

“With an extensive archive of historic drill core, we can systematically assess Minbrie’s base metals prospectivity without the need for immediate redrilling.

“Centrex’s past focus on magnetite exploration meant base metals were overlooked.

“We anticipate completing the assaying process within the next 8 to 10 weeks and will provide updates as results emerge.”
