Critical One Energy Confirms Target Depth Extension at Howells Lake Antimony-Gold Deposit

Executive Summary

• Advanced VTEM geophysical survey and geological modeling reveal significant expansion potential for the antimony‑gold deposit at the Howells Lake Project.
• Historical drilling intersected up to 75 % antimony over 8.35 m, and modeling indicates the mineralized zone may extend ≥400 m deeper along a 30 km strike length.
• Company will pursue follow‑up drilling to confirm and potentially increase resource estimates.

Key Details

• Geotech VTEM survey identified previously unrecognized characteristics in the East (V‑3) Zone, confirming a northwest‑striking, northeast‑dipping altered and sulphide‑mineralized zone dominated by stibnite, pyrite, and pyrrhotite.
• Historical drill intercept: up to 75 % antimony within a core interval of 5.37 % antimony over 8.35 m (plus associated gold).
• Modeling shows the EM anomaly extends to depth of ~400 m or more; the zone is controlled by late northwest‑striking, northeast‑dipping alteration and faulting.
• The project hosts a historic resource of 1.7 M tons at 1.4 % antimony (non‑NI 43‑101 compliant); new work required to produce a compliant estimate.
• Ongoing data review; follow‑up drilling program being planned to delineate and expand the antimony‑gold deposits.
• Qualified Person Bruce Durham, P.Geo, reviewed and approved technical content; historical data cannot be verified under current NI 43‑101 standards.
