Critical One working on data review for Howells Lake

Executive Summary

• Critical One Energy confirmed a significant target depth extension (up to 400 m) for the antimony‑gold mineralization in the East (V‑3) zone at Howells Lake using advanced VTEM geophysical surveying and geological modelling.
• Historical drilling intersected up to 75 % antimony over an 8.35 m interval, indicating high‑grade potential that could boost future resource estimates pending NI 43‑101 compliant work.
• The company plans follow‑up drilling to delineate and expand the deposit, leveraging the new geophysical model across its 25,000‑ha property.

Key Details

• Geophysical Survey: Recent VTEM survey identified a previously unrecognized electromagnetic anomaly associated with the East antimony‑gold zone.
• Depth Extension: Modelling suggests the mineralized zone may extend to 400 m depth or greater, far deeper than historically drilled intervals.
• Historical Intersections: Prior drilling at target V‑3 intersected up to 75 % antimony within a core interval of 5.37 % antimony over 8.35 m, accompanied by gold mineralization.
• Geological Interpretation: The zone is interpreted as a northwest‑striking, northeast‑dipping altered and sulphide‑mineralized structure (dominantly stibnite, pyrite, pyrrhotite) controlled by late‑stage alteration/faulting.
• Resource Context: Existing historical resource: 1.7 M t at 1.4 % antimony with associated gold; not NI 43‑101 compliant and requires re‑evaluation.
• Next Steps: Critical One is advancing plans for follow‑up drilling to confirm the extended depth, delineate additional targets along the 30‑km strike length, and ultimately develop an NI 43‑101‑compliant resource estimate.
• Qualified Person: Bruce Durham, P.Geo., independent QP under NI 43‑101, reviewed and approved the technical content; notes that historical data cannot be verified to current standards.
