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.”

Podium Minerals Reports Parks Reef Copper-Gold Zone Resource

/in , /by

THE DRILL SERGEANT: Podium Minerals (ASX: POD) released a Mineral Resource Estimate (MRE) from within the company’s 100 per cent-owned Parks Reef project in Western Australia.

Podium Minerals reported the new MRE for the copper-gold zone of mineralisation at Parks Reef, which is an additional zone to the existing platinum group metal (PGM) mineralised zone (PGM Zone).

The company said the MRE for the additional zone of copper-gold mineralisation expands the scale of Parks Reef, enhancing project optionality, and increasing the Podium Basket of payable metals.

Parks Reef now comprises two distinct and contiguous mineralised zones:

– Existing PGM Zone2:
MRE containing 7.6 million ounces 5E PGM,103,000 tonnes copper, 143,000 tonnes nickel and 27,000 tonnes cobalt.

– Additional Copper-Gold Zone:
Inferred MRE comprising 140,000 tonnes copper, 260,000 ounces gold, plus 60,000 tonnes nickel and 11,000 tonnes cobalt.

“The delineation of the substantial copper and gold mineralisation immediately above the hanging wall of the existing PGM and base metal horizon at Parks Reef is further demonstration of this deposit’s strategic value and ability to continue to surprise to the upside,” Podium Minerals executive chairman Rod Baxter said in the company’s ASX announcement.

“While geologically separate from the PGM reef, the additional copper-gold Resource substantially increases the Podium Basket price by 21 per cent at current spot prices, enhances optionality from a development perspective, and provides another strategic lever for us to consider as we progress the Parks Reef PGM Project.”

Baxter went on to explain the company has commenced a second phase of PGM flotation test work on samples sourced from Parks Reef in its December 2024 metallurgical drilling program.

This second phase of work is ongoing and is focussing on refining and optimising our flotation and waste rejection steps in the concentrator circuit,” he said.

“The work continues to further our understanding of the characteristics of Parks Reef ore as well as the flotation behaviour of the material, allowing us to deliver ongoing improvements in PGM recoveries as part of the test work program.”

Ausgold Reveals Broad Gold Zones at Regional KPG Prospects

/in , /by

THE DRILL SERGEANT: Ausgold (ASX: AUC) has widened the gold potential at the company’s 100 per cent-owned Katanning Gold Project (KGP) in Western Australia.

Ausgold reported that a recent Reverse Circulation (RC) drilling campaign at the KGP and surrounding 3,500 square kilometres tenement position that had been undertaken with three key objectives:

1) Close-spaced drilling to de-risk areas within the existing KGP mineral resource which are expected to comprise mining inventory in the early years of project operations;

2) Add to the existing resources at the KGP; and

3) Generate new gold mineralisation potential in the regional prospects surrounding the KGP.

The campaign consisted of 32 Reverse Circulation (RC) holes drilled across four key regional prospects along the Stanley Thrust – Zinger, Stanley Hill, Moulyinning and McDougalls.

“This drilling to establish the potential for regional satellite deposits represents the last piece of the puzzle in our current exploration campaign, with these assays from key prospects along the Stanley Thrust indicating an exciting opportunity to define a significant gold district surrounding the Katanning Gold Project,” Ausgold executive chairman John Dorward said in the company’s ASX announcement.

“The earlier phases of this drilling campaign – which comprised close-spaced drilling to increase confidence in the existing Resource and exploration drilling for Resource extensions – also returned positive results, further strengthening the robustness of this leading development project.”

Astral Resources Increases Spargoville MRE to 1.76M Ounces

/in , /by

THE DRILL SERGEANT: Astral Resources (ASX: AAR) gave Day Two punters at the 2025 RIU Resources Roundup by reporting an update to the Mineral Resource Estimate (MRE) for the company’s 100 per cent-owned Spargoville gold project near Kalgoorlie in Western Australia.

Astral Resources acquired the project via its recent takeover of Maximus Resources.

The restated JORC 2012 MRE has come in at 3 million tonnes at 1.4 grams per tonne gold for 139,000 ounces of contained gold.

“With compulsory acquisition of the outstanding shares in Maximus having now been completed, we considered that it was important to set our own baseline for the recently acquired Mineral Resources at the Spargoville gold project,” Astral Resources managing director Marc Ducler said in the company’s ASX announcement.

“Astral’s standard approach when testing the Mineral Resources for reasonable prospects for economic extraction (RPEE) includes a first step of regularising the block model, which is the process of varying the size of the block model shapes to approximate the size of the earth moving machinery likely to be used in open pit mining.

“This serves to more accurately reflect the amount of dilution likely to be experienced during open pit mining and provides a good base for the subsequent optimisations used to identify the potentially economic portion of the mineralisation models.

“Today’s update reflects this process of regularisation as well as the application of the latest revenue and cost data for the pit optimisations derived from contractor quotes obtained for the upcoming Mandilla PFS.

“The downward revision in contained metal is mostly attributable to the impact of dilution resulting from increasing the block dimensions to 4mE x 5mN x 5mRL and application of the Astral economic constraints.”
