Errington Metals Files Technical Report for Mineral Resource Estimate for the Sudbury Basin Project
Errington’s technical report validates its maiden resource while a Vale deal advances the Sudbury project.
Errington Metals Corp. filed an independent technical report titled "Technical Report – Mineral Resource Estimate for the Sudbury Basin Project" on SEDAR+ on November 9, 2026. The filing, prepared by DRA Americas Inc. with Ryan Wilson, P.Geo. and David Frost, FAusIMM, formalizes the maiden Mineral Resource Estimate (MRE) previously announced on September 22, 2026.
The report confirms 14.20 million tonnes (Mt) of Measured and Indicated (M&I) resources at 2.74% Copper Equivalent (CuEq) and 3.44 Mt of Inferred resources. It also outlines the company's planned Phase 2 55,000-metre drill program designed to grow resources, test regional targets, and advance the property.
The filing follows the September 22 MRE announcement and the October 15 drill results from the 1500 Zone, which highlighted high-grade polymetallic intersections outside the current resource wireframe.
Errington Metals Corp. filed a technical report to satisfy National Instrument 43-101 regulatory requirements following its initial Mineral Resource Estimate announcement. The filing does not introduce new resource numbers, economic parameters, or changes to the geological model.
The submission aligns with the company’s previously communicated timeline and the September 22 announcement. The market had already priced in the maiden resource estimate when it was released.
The filing provides regulatory validation of the technical work, reinforcing the credibility of the resource model for future feasibility studies and metallurgical testing. The impact is incremental and procedural, confirming the project's technical foundation without altering the financial outlook or near-term catalysts.
Errington Metals Corp. is an exploration-stage company focused on the Sudbury Basin Project in Northern Ontario, Canada. The flagship project hosts high-grade, polymetallic Volcanogenic Massive Sulfide (VMS) mineralization containing copper, zinc, lead, gold, and silver. The property encompasses three primary deposits: Errington, Vermilion, and Balfour, all located within the favorable Vermilion Formation host rock sequence.
The maiden MRE (effective September 20, 2026) defines 14.20 Mt of M&I resources at 2.74% CuEq, with over 80% classified as Measured or Indicated.
The company is advancing the project through a 55,000-metre Phase 2 drill program, metallurgical optimization studies, and environmental baseline work, targeting a technical study and updated resource estimate in 2027.
