Critical One Energy Inc. — Investor Relations & Filings
Critical One Energy Inc. is an upstream mining and exploration company focused on developing strategic critical mineral assets essential for clean energy and advanced technologies. The company's primary focus is the 100%-owned Howells Lake Antimony-Gold Project in Ontario, which represents one of North America’s largest known undeveloped high-grade antimony occurrences. Antimony is designated a critical mineral by Western governments due to its use in defense systems, batteries, and semiconductors, and its constrained global supply chain. Critical One Energy controls a district-scale land package (approximately 25,000 hectares) and is advancing the historic deposit, which features high-grade assays (up to 75% antimony and 14.19 g/t gold), toward a compliant resource pathway. The project is situated in a Tier-1 jurisdiction and is fully funded for its planned maiden drill program.
