- Commencing geological mapping and rock sampling to evaluate LCT-type pegmatite potential
- Fieldwork to focus on pegmatitic intrusive rocks, contacts with metavolcanic and metasedimentary host rocks, and structural corridors
- Regional geological records and remote sensing data will guide prospecting within the claims
- Vermillion Bay provides further opportunity to evaluate LCT-type pegmatite potential
Critical Resources (ASX: CRR) has commenced a prospecting program at its Vermillion Bay project in north-western Ontario, Canada.

A field crew will undertake prospecting, geological mapping and representative rock sampling within the claims, focusing on accessible bedrock exposures, intrusive contacts and structural corridors. Work will document mineralogy, alteration and pegmatite–host-rock relationships, with sampling used to assess rare- element geochemistry and prioritise follow-up exploration.
Fieldwork is expected to take approximately one to two weeks, with results to be reported once sample assays have been received and reviewed.
The program will focus on identifying pegmatitic intrusive rocks and assessing favourable intrusive contacts and structural settings within the approximately 1,000-hectare claim group. Historical geological information and regional remote sensing data will guide fieldwork, with observations and sampling used to assess rare- element potential and prioritise areas for follow-up exploration.
The Vermillion Bay project is located approximately 17 km west of the community of Vermilion Bay and approximately 70 km west of the company’s Mavis Lake lithium project in north-western Ontario. Both projects are accessible from the Trans-Canada Highway (Highway 17) corridor. Forestry roads and trails provide local access to portions of the Vermillion Bay claim group.
Previous exploration, primarily directed toward uranium and dimension-stone granite, documented pegmatitic intrusive rocks and host-rock relationships that provide a geological basis for evaluating LCT-type pegmatite potential.
Historical geological information and the broader remote sensing dataset will support field planning. The program will test whether these settings host pegmatites with characteristics consistent with LCT-type mineralisation.
Mavis Lake hosts a current Inferred mineral resource of 8.0 million tonnes (Mt) at 1.07% lithium oxide (Li2O).
CRR was down 7.69% to 0.6¢. Mkt cap $20.76M.
