Announcement PDF ASX ANNOUNCEMENT 6 November 2026 Critical Resources Limited – www.criticalresources.com.au Level 50, 108 St George’s Tce, Perth WA 6000 P: +61 (8) 9465 1024 E. info@criticalresources.com.au ASX:CRR Page 1 of 6 Geological mapping and sampling commencing at Vermillion Bay Lithium Project – Ontario, Canada Prospecting and rock sampling to evaluate LCT-type pegmatite potential at Critical Resources’ Vermillion Bay Project in Ontario, Canada. - Prospecting program: The Company is commencing geological mapping and rock sampling to evaluate lithium–caesium–tantalum (LCT)-type pegmatite potential at target areas within the Vermillion Bay lithium Project. - Target setting: Fieldwork will focus on pegmatitic intrusive rocks, contacts with metavolcanic and metasedimentary host rocks, and structural corridors, identified through historical geological information and interrogation of satellite data to prioritise areas for on ground exploration. - Historical context: Regional geological records and remote sensing data will guide prospecting within the claims, applying an LCT exploration focus to an area historically explored mainly for uranium and granite. - Ontario lithium portfolio: Vermillion Bay is an existing Company property that provides a further opportunity to evaluate LCT-type pegmatite potential alongside the Company’s Mavis Lake Lithium Project and regional prospects. - Access: Vermillion Bay is located close to the Trans-Canada Highway (Highway 17), with forestry roads and trails providing local access to support prospecting and follow-up exploration. Critical Resources Limited (‘Critical Resources’ or the ‘Company’, ASX:CRR) announces the commencement of 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 to evaluate the property’s lithium–caesium–tantalum (LCT)-type pegmatite potential. Fieldwork is expected to take approximately 1-2 weeks, with results to be reported once sample assays have been received and reviewed. No Exploration Results are reported in this announcement, and LCT-type pegmatite has not yet been confirmed on the Vermillion Bay claims. 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. VERMILLION BAY EXPLORATION PROGRAM The Vermillion Bay Project covers approximately 1,000 hectares, located approximately 17 km west of the community of Vermilion Bay and approximately 70 km west of the Company’s Mavis Lake Lithium Project near Dryden, 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. Critical Resources Limited – www.criticalresources.com.au Level 50, 108 St George’s Tce, Perth WA 6000 P: +61 (8) 9465 1024 E. info@criticalresources.com.au ASX:CRR Page 2 of 6 The property lies within the Kenora–Vermillion Bay geological corridor, where Archean metavolcanic and metasedimentary rocks are intruded by granitic bodies, pegmatitic granite, and late-stage pegmatite dykes and sills. Historical 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. 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. 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. Further details are provided in JORC Code Table 1 (Appendix B).
