Toronto, Ontario-(Newsfile Corp. - December 2, 2025) - Critical One Energy Inc. (CSE: CRTL) (OTCQB: MMTLF) (FSE: 4EF0) (formerly Madison Metals Inc.) ("Critical One" or the "Company"), a leading Canadian mining exploration company focused on critical metals and minerals, is pleased to announce that advanced geophysical and geological modelling of a recently completed VTEM airborne magnetic and electromagnetic (EM) geophysical survey has identified significant potential expansions to the mineralization at its Howells Lake Antimony-Gold Project ("Howells Lake Project"). The new interpretive results confirm the potential for discovering additional areas of mineralization containing both antimony and gold along highly altered and sulphide-bearing stratigraphic contacts that extend laterally westward for at least two kilometres (km). Modelled EM conductors also reside at depth below historic drilling and along strike of a magnetic low structural corridor. The new interpretive work indicates that the favourable stratigraphy is steeply dipping and extends to a depth of more than 300 metres (m). The Howells Lake Project is located approximately 120 km west of the Ring of Fire road corridor in the Thunder Bay North Mining Division of Ontario, Canada.
