Errington Metals Signs Definitive Agreement to Acquire Additional Sudbury Basin Mineral Properties

Errington Metals Corp. has signed a definitive agreement to acquire the Mid Zone property from Vale Canada Limited. The transaction adds approximately 1,270 hectares to the company's land package, increasing the continuous prospective strike length to over 20 km and connecting the Vermilion and Errington properties.

Consideration for the deal consists of 2,336,472 common shares, representing approximately 4.99% dilution, a 1.5% Net Smelter Returns (NSR) royalty, and deferred cash payments of $5 million each upon commercial production and processing of 5 million tonnes of ore. The NSR royalty increases to 2.5% if $2 million in exploration expenditures are not incurred within five years of closing, with a maximum aggregate NSR cap of 3%.

Vale becomes a key shareholder as a result of the transaction, joining Glencore, which already holds a significant position. The acquisition follows a non-binding term sheet announced on June 9, 2026, and is subject to regulatory and TSXV approvals, with closing expected by October 20, 2026.

Errington Metals Corp. (EM) has signed a definitive agreement, which serves as the expected follow-up to the June term sheet. This development is a routine positive rather than a market-moving surprise. Land consolidation remains a core part of the company's stated strategy to build a district-scale position in the Sudbury Basin.

The transaction involves approximately 5% equity dilution, a level that is manageable and aligns with previous financing and acquisition structures. Additionally, the deal includes a 1.5% NSR royalty, which is standard for the jurisdiction but introduces a performance clause that incentivizes timely exploration spending.

Strategic validation from Vale strengthens the project's credibility and aligns Errington with two major Sudbury operators, potentially easing future permitting or partnership discussions. There is no immediate change to near-term financials or cash flow, as the transaction is primarily strategic and exploratory.

Errington Metals Corp. (EM) is an advanced exploration company focused on the Sudbury Basin Project in Ontario, Canada. The flagship project encompasses three known near-surface mineralized centres: Errington, Vermilion, and Balfour, spanning a strike length of over 12.5 km. The deposit style is high-grade polymetallic Volcanogenic Massive Sulphide (VMS) targeting copper, zinc, lead, gold, and silver.

The company is advancing a 45,000-metre drilling program in 2026 to expand known mineralization and support an initial NI 43-101 compliant Mineral Resource Estimate. Historical resource estimates by Glencore (effective Dec 31, 2024) indicate approximately 12.1 million tonnes grading:

• 1.13% Cu
• 4.01% Zn
• 1.09% Pb
• 0.82 g/t Au
• 52.0 g/t Ag
