Executive Summary

  • Brunswick Exploration Inc. filed a NI 43-101 Technical Report defining a maiden Inferred Mineral Resource at its Mirage Project in Quebec, Canada.
  • The resource consists of 52.2 million tonnes at 1.08% Li2O and 131 ppm Ta2O5, placing the project among the largest undeveloped hard rock lithium resources in the Americas.
  • An additional conceptual exploration target of 40-50 Mt was identified, with metallurgical testwork suggesting a viable dense media separation (DMS) processing flowsheet.

Key Details

  • Maiden Inferred Resource: 52.2 million tonnes at 1.08% Li2O and 131 ppm Ta2O5.
  • Contained Lithia: In excess of 550,000 tonnes.
  • Cut-off Grade: 0.5% Li2O equivalent (Li2OEq).
  • Exploration Target: 40 million to 50 million tonnes grading 0.80% to 1.10% Li2O and 120 ppm to 145 ppm Ta2O5.
  • Geological Context: The resource is confined to a core area of approximately 1.5 by 3.0 kilometres. Over 70% of the MRE is contained within five dikes above a vertical depth of 150 metres, which remain open in several directions.
  • Exploration Potential: Lithium mineralization is observed up to 3.5 km from the MRE area, indicating substantial potential along strike.
  • Drilling Data: The estimate was based on 23,626 metres of drilling and 62 channel samples.
  • Metallurgy: Testwork indicates the potential for a dense media separation (DMS) only processing flowsheet to produce a high-quality concentrate.
  • Qualified Persons:
    • Simon T. Hebert (VP, Development) reviewed and approved the scientific and technical information.
    • Pierre Luc Richard, PGeo (PLR Resources) is the independent qualified person for the MRE.
    • Patrick Frenette, PEng (Synectiq Inc.) contributed to cut-off grade estimation and open pit optimization.
    • Jarrett Quinn, PEng (Synectiq) contributed to the metallurgical aspect.

Notable Quotes

  • "Brunswick Exploration remains one of the most compelling companies in the lithium space through the unique combination of advanced exploration in Quebec at both Mirage and Anatacau alongside an exciting global grassroot exploration program. I wish to thank the team and our consultants for this momentous achievement." — Killian Charles, President and CEO
