Critical examining 5km corridor at Corona target at Mavis Lake

Critical Resources (ASX: CRR) has commenced a field exploration program at the Corona pegmatite field within the Mavis Lake lithium project in Ontario, Canada.

Corona is located approximately four km north of the Mavis Lake lithium deposit and sits immediately north of Critical Resources’ existing mineral resource at Mavis Lake.

MD, Tim Wither, said Corona represents an opportunity to significantly expand the company’s drill pipeline ahead of the 2026 exploration program.

“Mavis Lake has the potential to evolve from a single-deposit asset into a multi-deposit lithium district. Corona has the potential to be a key part of that story,” Mr Wither said.

“The area sits within the same LCT pegmatite corridor as our existing mineral sesource, supported by an extensive geological database. Wide pegmatites mapped at surface and limited outcrop exposure suggest the potential for concealed LCT pegmatite systems across this largely unexplored five-kilometre trend.

“With systematic fieldwork now underway across this trend, we see a significant opportunity to define new drill targets and further support the development of Mavis Lake as a broader lithium district.

“We are advancing a targeted surface program to define the best possible targets before committing capital to mobilise the drills – a disciplined approach that gives us the best opportunity to identify new targets and expand our 2026 exploration program.’

The company has engaged an experienced exploration field crew with prior knowledge of the Mavis Lake project to undertake systematic prospecting and outcrop mapping across the Corona pegmatite field.

Field crews have mobilised to site, and prospecting is underway, with the field program expected to take approximately two weeks to complete.

The upcoming field program at Corona is supported by an integrated Mavis Lake exploration dataset, including geochemistry sampling, lithogeochemistry, LIBS-based pegmatite fractionation and high-resolution aeromagnetic data, as previously reported by the company.

CRR is steady at 0.9¢. Mkt cap $28.74M.
