Critical One Energy Inc. Unveils High-Grade Antimony Discovery at Howells Lake Project

TORONTO, May 14, 2025 — In a significant development for the mining sector, Critical One Energy Inc., formerly known as Madison Metals Inc., has announced the discovery of high-grade antimony intervals within the historical data of its Howells Lake Project. This revelation has sent ripples through the market, highlighting the potential for substantial economic gains given the current high prices of antimony.

The company, listed on the Canadian National Stock Exchange under the ticker CSE: CRTL, reported that drill hole MC-V3-79-22 yielded an impressive 75% antimony concentration within a core interval of 5.37% antimony over 8.35 meters. This discovery is part of a broader mineralization zone that spans over 5.0 kilometers, with additional gold mineralization detected, boasting values up to 14.19 grams per ton.

The Howells Lake Project, strategically located south of the Ring of Fire development area, presents a large resource potential with historical estimates suggesting 1.7 million tons at 1.4% antimony. This is particularly noteworthy as current antimony prices stand at US$25 per pound, a stark contrast to the historical price of US$1.50 per pound, underscoring the strong economic potential of the find.

However, the company acknowledges that the historical data, dating back to 1979-1984, requires modern verification to meet current NI 43-101 standards. No exploration drilling focused on antimony has been conducted in the past 40 years, and the true width of the mineralization could not be determined from historical drill intersections.

Despite these challenges, the discovery has positioned Critical One Energy Inc. as a key player in the antimony market, with a market capitalization of 13,656,212 CAD. The company’s close price as of May 8, 2025, was 0.5 CAD, with a 52-week high of 0.55 CAD and a low of 0.1275 CAD.

As the company moves forward, the focus will be on conducting modern exploration to validate the historical data and fully assess the project’s potential. This discovery not only highlights the untapped resources within the Howells Lake Project but also underscores the strategic importance of the region in the broader context of mineral development.

Investors and industry observers will be closely watching Critical One Energy Inc. as it navigates the next steps in bringing this promising project to fruition, potentially reshaping the landscape of antimony production in Canada.
