Critical Minerals Group (CMG) has announced encouraging results from initial metallurgical testing at its flagship Lindfield Project in North-West Queensland.
Preliminary testing of the upper seam revealed a 1.5 per cent vanadium oxide (V2O5) leach feed grade and an 85 per cent extraction of vanadium, with indications of potential for further enhancement.
The Lindfield Project, located 30km from Julia Creek, has shown the potential for a secondary product material – HPA (High Purity Alumina) with a product grading of 4N (99.99 per cent AI2O3) based on initial tests on mineralised samples.
The Lindfield Project Scoping Study is progressing as planned and is set to be completed by the end of Q3 2023.
Critical Minerals Group Limited Managing Director, Scott Winter, said that he was excited about the preliminary results of the metallurgical test.
“The early stage process testing of the vanadium material from each of the mineralised seams is a pivotal phase in the overall process and is crucial for the production of V2O5 and electrolyte products.
“Witnessing such promising results in a relatively short span for a seam not yet included in the resource is truly exhilarating for both the team and the project. Similarly, our first test on the alumina mineralised samples successfully produced our target 4N (99.99 per cent Al2O3) HPA product.”
Mr Winter also said that ”achieving such a high-grade HPA through a straightforward refinement stage bodes well for potential future production.
“These findings not only validate the superior quality of resources at the Lindfield Project but also offer a glimpse of the potential for further enhancement of the mineral resource material as the process undergoes refinement.
“The outcomes from the upper seam have empowered us to revisit and fine-tune the resource modelling, indicating a potential upside from our recently declared resource. These results are being incorporated into the Scoping Study, which is in progress and slated for completion by the end of Q3 2023.”
