Critical One Energy Inc. reports developments as a Canadian mining exploration company focused on critical metals and minerals. Its updates center on the Howells Lake Antimony-Gold Project in Ontario's Thunder Bay Mining Division, including exploration permitting, Ontario Junior Exploration Program funding, geophysical interpretation, drilling activity, and near-surface antimony and gold mineralization.
Company news also covers its broader critical-minerals portfolio, including uranium and copper assets in Namibia's Erongo uranium province, as well as exploration agreements with Indigenous communities, strategic advisory appointments, capital-market communications, and stock-option grants tied to its public-company governance.
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.
Key program enablers include >3,000 km of VTEM geophysics, Ontario Junior Exploration Program funding approval, Exploration Permit PR-24-000227, and the immediate grant of 600,000 stock options exercisable at CDN$0.80 for five years. A Qualified Person notes technical data are historical and cannot be independently verified.
Critical One Energy (OTCQB: MMTLF) signed an exploration agreement with Eabametoong First Nation and has commenced Phase I diamond drilling at the Howells Lake Antimony-Gold Project on March 12, 2026. The project covers ~25,000 hectares across a 30 km strike and cites a historical resource of 1.7 million tonnes at 1.4% Sb, while historical assays and resource estimates are not NI 43-101 compliant and require verification by current drilling.
The agreement includes community engagement, issuance of CDN$250,000 in shares within 30 days, cash considerations, and expense coverage tied to the project's life.
Critical One Energy (OTCQB: MMTLF) announced a mutual termination of the August 7, 2025 purchase agreement with Dark Star Minerals, regaining full control of its Khan and Cobra uranium projects in Namibia. As part of the unwind, Critical One returned 14,200,000 Dark Star common shares and no termination fees were payable.
The company confirmed the CEO ended his advisory role with Dark Star effective immediately and reiterated focus on the Howells Lake Antimony-Gold Project, where an exploration permit was recently approved ahead of a maiden drill program.
Critical One Energy (OTCQB: MMTLF) received Ontario Exploration Permit PR-24-000227 for the Howells Lake Antimony-Gold Project on February 23, 2026. The permit enables an initial drilling program across ~25,000 hectares and a 30 km strike, aiming to test historical mineralization including a reported 1.7 million tons at 1.4% antimony.
The company says drilling will follow consultation with Eabametoong First Nation and use environmental best practices; historical data remain unverified under NI 43-101 and require confirmation.
Critical One Energy (OTCQB: MMTLF) received Ontario Government approval for initial funding under the Ontario Junior Exploration Program (OJEP) for the Howells Lake Antimony-Gold Project.
The grant will support accelerated drilling starting spring 2026, community engagement, and ecological stewardship across a ~25,000-hectare land package with historical resource indications.
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.
Trenkler will lead technical strategy and exploration at the Howells Lake Antimony-Gold Project, described as Canada’s largest known undeveloped antimony deposit, located ~200 km from the Ring of Fire in Thunder Bay Mining Division, Ontario. He brings over 15 years of exploration experience, including work at Wesdome’s Eagle River Mine and IAMGOLD’s Côté Gold project. Trenkler holds a PhD in Earth Science and is registered with Professional Geoscientists Ontario.
Critical One Energy (OTCQB: MMTLF) has announced significant findings from advanced geophysical and geological modeling at its Howells Lake Antimony-Gold Project in Ontario, Canada. The analysis revealed substantial expansion potential of the antimony-gold deposit, with mineralization extending to depths of up to 400 meters.
Key findings include historical drilling intersections of up to 75% antimony within a core interval of 5.37% antimony over 8.35 meters. The project hosts a historical resource of 1.7 million tons at 1.4% antimony with associated gold mineralization, though this estimate is not NI 43-101 compliant. The property spans 25,000 hectares with a 30 km strike length of favorable geology.
Critical One Energy (OTCQB: MMTLF) has appointed Robert Suttie as its new Chief Financial Officer, effective September 15, 2025.
