Errington Metals Continues to Expand Mineralization at the Balfour Zone

Errington Metals Corp. (EM) reported 2026 winter/spring drill results from the Balfour Zone at its wholly owned Sudbury Basin Project. The company states the Main and West Zones were extended 100 m eastward along strike and 50 m down dip, with both remaining open along strike and at depth.

Headline intercepts include: - EMB-26-058, Balfour West: 7.2 m at 1.40% Cu, 4.99% Zn, 3.51% Pb, 0.24 g/t Au, 146.4 g/t Ag (reported 5.10% CuEq) - EMB-26-059, Balfour West: 10.4 m at 0.52% Cu, 4.78% Zn, 2.15% Pb, 0.25 g/t Au, 102.6 g/t Ag (reported 3.51% CuEq) - EMB-26-060, Balfour West: 4.9 m at 1.45% Cu, 6.97% Zn, 2.87% Pb, 0.20 g/t Au, 101.0 g/t Ag (reported 5.20% CuEq) - EMB-26-069, Balfour Main: 4.9 m at 0.24% Cu, 5.19% Zn, 3.24% Pb, 0.31 g/t Au, 226.3 g/t Ag (reported 4.72% CuEq) - EMB-26-071, Balfour Main: 5.6 m at 0.96% Cu, 9.71% Zn, 3.79% Pb, 0.23 g/t Au, 120.7 g/t Ag (reported 5.92% CuEq)

Table 2 lists 21 drill collars for holes EMB-26-048 through EMB-26-074. Assay results are shown for 19 of those holes; EMB-26-063 and EMB-26-068 are listed as collars but shown with no assay intercepts in Table 1. No specific cutoff grade is disclosed. True widths are stated as expected to be 70% to 100% of drilled widths.

Errington Metals Corp. (EM) is a pre-revenue junior explorer that does not yet have an NI 43-101 mineral resource, and the Balfour project is not included in the historical resource figures presented to investors. The recent release represents a step-out and continuity result rather than a new discovery, supporting the planned initial mineral resource estimate without adding new tonnes, reserves, or economics.

The relevant benchmark remains the May 27, 2026 Balfour release, which reported hole EMB-25-022 intersecting 6.8 m with 10.98% Zn, 7.92% Pb, 1.25% Cu, 227.2 g/t Ag, or 6.98% CuEq, and EMB-25-010 with a broad 12.1 m at 8.25% Zn. While the current best intervals are moderately below that anchor on zinc-thickness and reported CuEq·m, the new drilling has extended the mineralized footprint 100 m along strike and 50 m down dip, with multiple holes hitting high-grade VMS material.

The stock re-rated from C$2.85 around May 27 to C$4.05 by June 2, closing at C$3.80 on August 14. The current drilling is consistent with the project the market is already pricing in, rather than representing a large positive surprise. Meanwhile, the August 11 private placement raised gross proceeds of C$34.5 million, substantially improving liquidity relative to the Q1 2026 financial statements, which showed only C$1,775 in cash and a working capital deficit.

Errington Metals Corp. is a TSXV-listed Canadian exploration company focused on polymetallic VMS mineralization in the Sudbury Basin, Ontario. The Sudbury Basin Project covers three known mineralized centres—Errington, Vermilion, and Balfour—along a 12.5 km strike length, with commodity exposure to copper, zinc, gold, silver, and lead.

Historical resource estimates, which are not verified as current NI 43-101 resources, include Errington at 8.9 Mt at 1.13% Cu, 4.01% Zn, 1.09% Pb, 0.82 g/t Au, and 52.0 g/t Ag, and Vermilion at 3.2 Mt at 1.31% Cu, 4.36% Zn, 1.17% Pb, 0.94 g/t Au, and 53.0 g/t Ag. Balfour is not included in that historical resource and is being advanced through the current drill program. The company has a planned 45,000-metre drill campaign and is targeting an initial mineral resource estimate in H2 2026.

In July 2026, Errington announced an agreement to acquire 2,727 hectares of unpatented mining claims, expanding its land position by roughly 48% near the Garson mine area. Management includes Matthew Gollat as President and CEO, Frank Santaguida as VP Exploration, and Gavin Nelson as CFO. Glencore holds a strategic position according to the investor presentation.
