THUNDER BAY, ON, Sept. 10, 2026 /CNW/ -- Errington Metals Corp. (TSXV: EM) ("Errington" or the "Company") is pleased to announce that further to its news release dated June 9, 2026, its wholly-owned subsidiary, Errington Metals Inc. ("Subco") has entered into a purchase and sale agreement (the "Purchase Agreement") with Vale Canada Limited ("Vale") pursuant to which Subco will acquire (the "Acquisition") 24 freehold parcels and four mining licences of occupation located in the Sudbury Basin, Ontario (collectively, the "Property").

The Acquisition consolidates the Errington and Vermilion properties and will add approximately 1,270 hectares of prospective ground to Errington's Sudbury Basin Project, increasing the Company's total property position to approximately 9,000 hectares (excluding the Garson Property). With the addition of this ground, Errington will control approximately 20 kilometres of continuous prospective strike length along the key favourable host rock sequences within the Sudbury Basin Project adding to the potential for discovery of new polymetallic sulphide mineralized zones (see image 1)

The Mid Zone Property contains the same favourable host rock sequence associated with massive sulphide mineralization at Vermilion, Errington and Balfour. The Vermilion Formation chert-carbonate unit, which is the immediate host to mineralization elsewhere within the Sudbury Basin Project, is exposed at surface on the Property. Historical exploration completed more than 30 years ago intersected polymetallic mineralization close to surface; however, limited follow-up work has been conducted since that time.

Errington plans to complete reconnaissance field work and geophysical surveys at Mid Zone as part of its broader strategy to integrate and connect existing datasets across the Sudbury Basin Project and generate new targets for drilling.

"This Acquisition represents an important step in advancing the Sudbury Basin Project and expanding Errington's exposure to the favourable host rock sequences associated with our known mineralized zones," said Matthew Gollat, President and CEO of Errington Metals. "We are also very pleased to welcome Vale as a new holder of Errington. With Glencore already holding a significant ownership position, Errington now counts the two leading operators in Sudbury as shareholders. We believe this acquisition strengthens the strategic relevance of our land position and provides further validation of the project's scale and potential."

Under the Purchase Agreement, the consideration payable for the Property consists of the issuance by the Company to Vale on the closing date of 2,336,472 common shares of the Company (the "Consideration Shares"), representing approximately 4.99% of the Company's outstanding common shares on a non-diluted basis as of April 22, 2026 being the date of the initial listing of the common shares on TSX Venture Exchange ("TSXV"), and the grant by Subco of a 1.5% net smelter returns royalty on the Property (the "Royalty").

If Subco has not incurred aggregate $2,000,000 of exploration expenditures on the Property within five years of the closing date of the Acquisition, the Royalty rate will be increased from 1.5% to 2.5%, subject to a maximum aggregate net smelter returns of 3%, inclusive of existing royalties as of the closing date of the Acquisition, in respect of any individual Property, provided that Vale holds the Consideration Shares (or the equivalent number of common shares of the Company) from the closing date to the date that the Royalty rate is increased.

In addition, Subco has agreed to pay to Vale (i) $5,000,000 within 30 days of Subco achieving commercial production from the mining and processing of ore from a deposit on the Property, and (ii) a further $5,000,000 within 30 days of Subco producing and processing an aggregate of five million tonnes of run of mine ore from the Property.

Completion of the Acquisition is subject to a number of customary conditions, including the receipt of all required regulatory and third-party approvals, including all necessary severance consents pursuant to the Planning Act (Ontario) and all required approvals from the TSXV for the Acquisition and the issuance of the Consideration Shares. The closing of the Acquisition is expected to occur five business days following receipt of the required regulatory and governmental approvals and, in any event, no later than October 20, 2026, subject to extension by three months from October 20, 2026 to January 20, 2027 in certain circumstances. The Consideration Shares will be subject to a four-month hold period under applicable Canadian securities laws from the closing date of the Acquisition.
