Critical One Energy (OTCQB: MMTLF) reported new drill assays from its Howells Lake antimony-gold project in Ontario. Hole HWL-2026-006 cut 4.0 m grading 70.2% antimony within 8.0 m at 42.2% Sb, plus a deeper 7.3 m interval at 1.62% Sb.
All eight holes near the historic Howells Lake East Antimony Zone intersected visible stibnite. Results suggest potential for direct shipping ore to North American buyers. QA/QC used blanks, standards and accredited AGAT Labs; overlimit (>5% Sb) values are semi-quantitative pending further mineralogical work.
Critical One Energy (OTCQB: MMTLF) appointed General (Ret.) Charles A. Flynn to its Strategic Advisory Board, effective April 16, 2026.
General Flynn will advise on U.S. strategic engagement, government and defence relationships, supply chain partnerships and offtake discussions as the company advances drilling at the Howells Lake Antimony-Gold Project. The company granted him 200,000 stock options at CDN$1.03 for five years.
Critical One Energy (OTCQB: MMTLF) reported visible, near-surface antimony mineralization in the first Phase I diamond drill hole (HWL-2026-001) at Howells Lake. HWL-2026-001 reached 201 metres with multiple stibnite-bearing zones within the first ~100 metres, starting at 24 metres.
Core is being logged and samples were submitted to AGAT Laboratories; assays are pending. The project has a historical, non‑NI 43-101 estimate of 1.7 million tons at 1.4% antimony, which the company says requires verification.
Critical One Energy (OTCQB: MMTLF) will host a live investor webinar on March 19, 2026 at 10:30 a.m. EDT to discuss Phase I drilling at the Howells Lake Antimony-Gold Project following an exploration agreement with Eabametoong First Nation.

Critical One Energy (OTCQB: MMTLF / CSE: CRTL) reported that advanced VTEM airborne magnetic and EM modelling at its Howells Lake Antimony-Gold Project identified significant extension potential for antimony and gold mineralization.
Key findings: modelled EM anomalies extend laterally at least 2 km west, occur >300 m deep, and lie below historic drill holes; favourable steeply dipping stratigraphy and structural corridors were mapped; historical intercepts include up to 4.7% antimony and 25.5 g/t gold, and a historical non-NI resource of 1.7 million tons @ 1.4% Sb.
Critical One Energy (CSE: CRTL; OTCQB: MMTLF) announced on November 13, 2025 the appointment of Matthew Trenkler, PhD, P.Geo as Chief Geological Officer, effective immediately.
