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.

[ "Appointment of highly experienced CFO with 25+ years in financial management", "New CFO brings extensive public company and mining sector expertise", "Seamless leadership transition with immediate effectiveness" ]Critical One Energy (OTCQB: MMTLF) has acquired the KCR Gold Project adjacent to its Howells Lake Antimony-Gold Project in Ontario's Thunder Bay Mining Division. The key highlight is the Slam Gold Zone discovery, where a historic drill hole intersected visible gold with assays up to 64.1 g/t gold over one metre within a broader interval of 3.54 g/t gold over 20.4 metres.
The acquisition, costing CDN$6,000 and 50,000 common shares, includes a 2% NSR. The company now controls over 30 km of geological trend and 25,000 hectares of land. The project area includes a historical resource of 1.7 million tons at 1.4% antimony with associated gold mineralization (non-43-101 compliant). Critical One is fully funded with CDN$3.3 million from a recent private placement for near-term exploration.
Critical One Energy (OTCQB: MMTLF) has acquired an 18.5% stake in Dark Star Minerals, securing a significant position in Namibian uranium development. This strategic investment follows Critical One's sale of its Khan and Cobra uranium projects to Dark Star for US$3.5 million, which included 14 million Dark Star common shares and a 2% gross overriding royalty on metal production.
The transaction positions Critical One as a major stakeholder in Dark Star's uranium projects in Namibia's Erongo province, where previous exploration at Khan West yielded high-grade results of up to 8.47% U₃O₈. While maintaining this strategic uranium interest, Critical One will primarily focus on its Howells Lake Antimony-Gold Project in Ontario's Thunder Bay Mining Division.
Critical One Energy Inc. (OTCQB: MMTLF) has expanded its Howells Lake Antimony-Gold Project in Ontario, Canada by 67%, adding 9,979 hectares to reach a total of 24,887 hectares. The expansion follows the discovery of high-priority antimony and gold anomalies in multiple unexplored areas.
The project contains Canada's largest undeveloped antimony deposit, with historical resources of 1.7 million tons at 1.4% antimony. Recent drilling at the V-3 area revealed impressive results of up to 75% antimony within 5.37% antimony over 8.35 meters. The company has completed over 3,000 km of VTEM airborne geophysics and is fully funded for exploration following a CDN$3.3 million private placement.
This strategic expansion positions Critical One to capitalize on surging antimony prices, which have increased by over 550% since 2015, driven by global supply constraints and China's 2024 export ban.
Critical One Energy (OTCQB: MMTLF) has finalized a definitive agreement with Dark Star Minerals for the sale of its uranium assets in Namibia. The deal involves the Khan and Cobra Uranium Projects, with Dark Star making staged payments totaling US$760,000 in cash and significant share issuances over two years.
The agreement includes 14,000,000 Dark Star shares issued upon execution and additional share payments valued at US$1.75 million. Once payments exceed US$3.5 million, Critical One will receive a 2% gross overriding royalty on all metals produced, with Dark Star having the option to buy back 0.5% for US$1.5 million.
Critical One Energy (OTCQB: MMTLF) has completed a CEO-led field investigation at its Howells Lake Antimony-Gold Project in Ontario's Thunder Bay Mining Division. The company successfully located and validated historic trenches, surface antimony mineralization, and drill hole collars at the site.
Key findings include the identification of broad zones of carbonate and sericite alteration up to 100 meters wide, confirmation of antimony-gold mineralization locations, and the discovery of historic drill cores from 1984 and 1986. The company plans to conduct a comprehensive state-of-the-art airborne magnetic and electromagnetic geophysical survey across the 26-kilometer-long property.
The project represents Canada's largest undeveloped antimony deposit, strategically positioned near Ontario's Ring of Fire corridor. This is particularly significant as over 80% of global antimony supply is currently controlled by China and Russia.
