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

TORONTO, Oct. 01, 2025 (GLOBE NEWSWIRE) -- Critical One Energy Inc. (formerly Madison Metals Inc.) (“Critical One” or the “Company”) (CSE: CRTL) (OTCQB: MMTLF) (FSE: 4EF0), a leading Canadian mining exploration company focused on critical metals and minerals, is pleased to announce that advanced geophysical and geological modelling has confirmed significant expansion potential of the antimony-gold deposit at its Howells Lake Antimony-Gold Project (“Howells Lake Project”). The results underscore the potential for increased resource estimates, which Critical One will work to confirm with further drilling. The Howells Lake Project is located approximately 200 kilometres (km) from the Ring of Fire corridor in the Thunder Bay Mining Division of Ontario, Canada.
The recent Geotech VTEM geophysical survey, proprietary interpretive analysis combined with detailed geological modelling, has identified previously unrecognized characteristics of the antimony-gold mineralization at the East (V-3) Zone at Howells Lake. The data analysis reveals:
- Previous drilling at historical target V-3 (Howells Lake East Zone) intersected up to
75% antimony within a core interval of5.37% antimony over 8.35 meters*, alongside gold mineralization - Alteration mapping, data reconstruction, and geophysical model interpretation show the East Antimony-Gold Zone to be a northwest-striking, northeast-dipping altered and sulphide mineralized zone (mainly stibnite, pyrite, pyrrhotite)
- Modelling of the newly defined EM anomaly associated with the mineralized zone shows an extension to depth of up to 400 m or more
- Antimony-gold mineralization is interpreted to be controlled by a late northwest-striking, northeast-dipping alteration and fault zone
- Modelling is being used to help confirm and categorize numerous other antimony-gold targets along the 30 km strike length of favourable geology on the Company’s 25,000-hectare property
“Our team’s rigorous application of cutting-edge geophysical techniques and geological modelling has unlocked significant new potential at Howells Lake,” said Duane Parnham, Founder, Executive Chairman and CEO of Critical One. “These results validate our exploration strategy and position Howells Lake as a cornerstone asset with exceptional antimony and gold exploration and development potential.”
Geological and geophysical data review and analysis are ongoing. Critical One is also advancing its exploration program plans for follow-up drilling to delineate and expand the antimony-gold, deposits (see the press releases dated August 28, 2025 and September 4, 2025, respectively).
