Cross Lake Project

Project Location & Area:

• Located in northern Manitoba, Canada — a tier-one jurisdiction for lithium exploration

• ~120km south of the mining town of Thompson

• Proximal to the Jenpeg hydro-electric station, supporting low-emission development

• Covers over 600km² of tenure with access to road and energy infrastructure

​

Project History:

• Part of the historical TANCO exploration region, renowned for lithium-bearing pegmatites

• Historical drilling includes 23 diamond holes for ~2,500m across mapped pegmatite zones

• Multiple intervals logged with visible spodumene, though few were assayed for lithium

• Leeuwin is the first explorer to systematically assay core for lithium in this area

​

Value Drivers:

• Resampling of historical core has confirmed lithium-bearing spodumene in multiple holes

• Significant spodumene intercepts from diamond drilling include:

  • 10.7m @ 1.24% Li₂O from 36.0m (CRL22-003)

  • 9.2m @ 1.49% Li₂O from 31.0m (CRL22-005)

  • 4.9m @ 1.63% Li₂O from 68.0m (CRL22-010)

  • 4.2m @ 1.48% Li₂O from 43.0m (CRL22-004)

  • 3.3m @ 1.95% Li₂O from 21.0m (CRL22-002)

• Spodumene dykes up to 10m wide observed in outcrop and core

• Over 6.5km of mapped prospective strike within a district-scale pegmatite trend

• Underexplored tenure with potential for high-grade LCT pegmatites and follow-up drilling planned
