Critical Metals expects new feasibility study for Wolfsberg lithium project in Q1 2025
Wolfsberg represents Europe's first fully permitted spodumene mine, and potentially its first lithium concentrate producer.
The joint venture of Vancouver-based Azincourt Energy and New Age Metals has received assays up to 4.1% lithium oxide from the Silverleaf pegmatite samples at their Lithium One project 125 km northeast of Winnipeg.
The results follow a comprehensive ground mapping and sampling field program this summer. High grades were also found in nine samples that exceeded 2% and five samples that exceeded 3% lithium oxide. A second sample over 4% was also collected.
A sample of spodumene blade was also sent for analysis. It assayed 8.76% lithium oxide. Azincourt said that spodumene crystals from Silverleaf contained from 3.74% to 8.04% lithium dioxide.
Several other samples from Silverleaf contained high grades of rubidium oxide, which might be recovered as a by-product of lithium production. Rubidium is commonly used in speciality glass for sectors such as fibre optic telecommunications, night vision devices, photoelectric cells, and photomultiplier tubes.
