Critical One Energy Inc. (CSE: CRTL) has released assay results from four drill holes at its Howells Lake Antimony-Gold Project in Ontario, extending antimony mineralization 30 metres northeast of the high-grade East Zone. The results also confirm gold mineralization beneath the East Zone and add further gold intercepts in the West Zone. Investors may be watching these results closely as the company advances toward a planned mineral resource estimate.

Key Points

  • Critical One Energy Inc. (CSE: CRTL, OTCQB: CTLOF, FSE: 4EF)
  • Four new drill holes at Howells Lake return antimony and gold assays, extending the East Zone mineralization envelope northeast
  • HWL-2026-017 returned 11.9 m grading 1.75% Sb, including 3.6 m at 3.78% Sb; HWL-2026-014 returned 7.0 m grading 1.49 g/t Au, including 3.0 m at 2.69 g/t Au
  • Investors may watch for pending assays from multiple holes, including HWL-2026-015 and HWL-2026-018 through HWL-2026-028

Howells Lake East Zone Antimony Results Exceed Early-Stage Expectations

Drill hole HWL-2026-017, drilled down-dip of the previously released HWL-2026-016, returned 11.9 metres grading 1.75% antimony, including 3.6 metres at 3.78% antimony, extending the mineralization envelope 30 metres to the northeast of the East Zone. Near-surface results from HWL-2026-009 added 1.15 metres grading 3.32% antimony and 3.75 metres grading 0.90% antimony in the East Zone. The release states that assays from 168 metres to 236 metres in HWL-2026-017 remain pending, meaning additional data from this hole is still outstanding.

Gold Mineralization Confirmed Below East Zone and in West Zone

HWL-2026-014 confirmed gold mineralization beneath the high-grade East Zone antimony corridor, returning 7.0 metres grading 1.49 g/t gold, including 3.0 metres at 2.69 g/t gold, alongside a polymetallic interval of 6.0 metres grading 0.39% antimony, 0.43 g/t gold, and 0.40% zinc. In the West Zone, HWL-2026-013 returned 5.0 metres grading 0.57 g/t gold. The release states these gold-bearing horizons will continue to be evaluated for potential inclusion in a future mineral resource estimate.

2026 Drill Program Targeting 15,000 Metres Across Both Zones

The company disclosed an updated target of 15,000 metres to be completed by the end of the 2026 campaign, with drilling ongoing in both the East and West Zones. NQ-diameter diamond drilling is continuing with the goal of identifying antimony-gold mineralization at depths greater than 200 metres. The company also announced that HQ-diameter drilling will be initiated for larger-scale metallurgical analysis. Multiple holes — including HWL-2026-015, HWL-2026-018 through HWL-2026-028, and five dedicated metallurgical holes — have assays pending. The immediate share price impact was not clear from available public information.
