Errington Metals Corp. is a Canadian exploration and development company specializing in critical and precious metals and advancing its wholly owned Sudbury Basin Project in the Sudbury mining district of Ontario, Canada. Founded in 2024 and headquartered in Thunder Bay, Ontario, the company focuses on high-grade volcanogenic massive sulphide-style mineralization and is pursuing resource expansion and discovery through systematic drilling and technical work. Its core activities include mineral exploration; property acquisition and consolidation; drilling and geological evaluation; and the planned delineation of an initial mineral resource estimate. The company’s principal project comprises the Sudbury Basin Project, which includes the Errington and Vermilion properties and, following recent acquisitions, approximately 9,000 hectares of land position in the district, excluding the Garson Property. Errington Metals’ recent developments include the commencement of trading on the TSX Venture Exchange under the symbol EM in April 2026; the launch of a 45,000-metre drill program designed to support an initial mineral resource estimate and test regional targets; the release of initial 2026 drilling results confirming multiple high-grade copper-zinc-lead-gold-silver intercepts at the Errington Zone; the engagement of TB Investors Relations to support communications and market outreach; and the signing of a definitive agreement with Vale Canada Limited to acquire additional Sudbury Basin mineral properties, consolidating the project’s ground position and expanding prospective strike length.
