Lithium project developer, Critical Resources Limited (ASX:CRR) (“Critical Resources” or “the Company”) is pleased to report on its activities for the quarter ended 31 March 2023 (“the Quarter”). The focus for the Quarter remained on the advancement of the Company’s flagship asset, the Mavis Lake Lithium Project.
Highlights
- Commencement of a 20,000 meter drill campaign at Mavis Lake, immediately reinforcing the successful 2022 drill program. The campaign was designed to test known outcroppings of lithium-bearing pegmatite across the project, whilst also seeking to extend the known mineralisation of the Mavis Lake Main Zone.
- Drilling from early January to the end of March, identified multiple thick, high-grade intercepts which were announced throughout the Quarter.
- A new high grade mineralized zone discovered south of Mavis Lake Main Zone (“South Zone”).
- Consistent assay results, with sections of very high grade mineralisation received, up to 3.34% Li2O.
- First concentrate produced from Mavis Lake metallurgical test work program with full test work outcomes released subsequent to the quarter end.
- Work continued on the Maiden Mineral Resource Estimate for Mavis Lake, the Company will release the resource estimate in the coming weeks, as soon as it is finalised.
