Thunder Bay, Ontario, September 3, 2026 –Errington Metals Corp. (TSX.V: EM)(“Errington” or the “Company”) is pleased to announce initial results from its 2026 Spring exploration program at the Errington Zone.

The results include multiple polymetallic intercepts and, importantly, continue to demonstrate the potential to grow the deposit. Drilling has extended the Company’s understanding of mineralization in the eastern portion of the zone, where elevated gold and silver values continue to contribute meaningfully to overall grade and potential value per tonne. 

Press Release Summary:

• Initial 2026 drilling results confirm multiple high-grade copper-zinc-lead-gold-silver intercepts at the Errington Zone, including 11.0 metres grading 6.41% CuEq in hole EME-26-086.
• Results continue to demonstrate the potential to expand mineralization at depth, where the Errington Zone remains open for further growth.
• Elevated gold and silver values in the eastern part of the zone highlight the potential for precious metals to enhance overall value per tonne.
• New drilling supports an evolving geological model in which mineralization may be faulted and offset down-dip rather than closed off by folding, creating additional exploration opportunities.
• Borehole electromagnetic surveys are underway to identify conductive sulphide targets and help guide the next phase of deeper drilling.

Highlights:

• 11.0m grading 1.75% Cu, 8.63% Zn, 2.05% Pb, 1.66 gpt Au, 104.5 gpt Ag, 6.41% CuEq in EME-26-086
• 19.3m grading 0.69% Cu, 3.29% Zn, 1.12% Pb, 0.83 gpt Au, 42.6 gpt Ag, 2.68% CuEq in EME-26-089
• 12.3m grading 0.43% Cu, 6.10% Zn, 1.41% Pb, 1.22 gpt Au, 41.7 gpt Ag, 3.49% CuEq in EME-26-100
• 8.90m grading 0.69% Cu, 8.78% Zn, 2.57% Pb, 0.91 gpt Au, 86.2 gpt Ag, 4.83% CuEq in EME-26-083

Matthew Gollat, President and CEO of Errington Metals, commented:

“These initial results from the 2026 drill program are an exciting step forward for Errington.

 

“We continue to intersect strong polymetallic mineralization at depth, including meaningful precious metals values that can enhance the overall value of this opportunity.

 

“Just as important, the drilling is improving our understanding of the structures that control mineralization and is opening up new areas to follow the system down-dip.

 

“The Errington Zone remains open, and these results give us a clear path to target additional growth as we advance the next phase of drilling.”

The 2026 program was designed to test the depth extension along the full strike extent of the Errington mineralized zone, including the West and 1500 areas, where assays remain pending.

At Errington Main, drilling tested extensions of mineralization within the major fault blocks, with an initial focus on the eastern portion of the Main and Christie Blocks. Results continue to show elevated gold associated with massive sulphide mineralization in the eastern part of Errington, building on the higher precious metals signature first recognized in 2025 drilling, when drill hole EME-25-047 intersected 21.5 m grading 0.38% Cu, 0.08% Zn, 0.13% Pb, 1.23 g/t Au and 24.7 g/t Ag (see Errington’s June 9, 2026 press release).
