Errington Metals Identifies Growth Potential at the 1500 Zone

Highlights

• EME-26-108: 8.3 m grading 9.59% CuEq¹ (5.86% Cu, 7.26% Zn, 2.59% Pb, 0.57 g/t Au and 313.8 g/t Ag) from 409.5 m

• EME-26-105: 8.0 m grading 4.70% CuEq¹ (3.33% Cu, 3.81% Zn, 1.44% Pb, 0.24 g/t Au and 73.3 g/t Ag) from 436.45 m

• Potential extensions of mineralization up dip and down dip remain targets for further drilling, including areas containing copper-rich stringer mineralization

• Drill targets remain: historical drilling intersected massive sulphide mineralization east of the 1500 Zone, with no follow-up completed

• Planned downhole electromagnetic surveys will help identify conductive targets and guide follow-up drilling at the 1500 Zone during Phase 2

THUNDER BAY, ON, Oct. 15, 2026 /CNW/ -- Errington Metals Corp. (TSXV: EM) (OTCQX: ERRMF) ("Errington" or the "Company") is pleased to report initial drill results from the 1500 Zone at the Errington Deposit. The limited program successfully tested gaps within the existing resource wireframe, intersected high-grade polymetallic mineralization and provided new structural information to support targeting for the Company's Phase 2 drill campaign.

A video overview of the drill results can be found at: https://vrify.com/meetings/recordings/2f892738-9aa2-4ba2-b763-a7d98f38023d

"These initial results, which were drilled outside of the optimized stopes in our mineral resource, demonstrate the high-grade potential of the 1500 Zone and reinforce our view that meaningful opportunities remain within and beyond the current model," said Matthew Gollat, President and CEO of Errington Metals. "The combination of strong copper, zinc and silver grades, limited historical drilling and untested extensions gives us a compelling target for Phase 2 drilling. Downhole geophysics and follow-up drilling will help us refine the structural model and systematically test the zone's growth potential."

The 1500 Zone is interpreted as a fault-displaced portion of the Errington Deposit. It occurs at depth without a known surface expression, and its up-dip extent remains largely untested (Figure 1). Seven holes were drilled to test gaps within the historical mineralized envelope and begin evaluating extensions along strike and down dip. Drilling into one significant gap intersected high-grade copper mineralization consisting of chalcopyrite stringers cutting massive pyrite-sphalerite mineralization (Figures 2 and 4), with elevated silver associated with the copper-rich interval (Table 1). EME-26-116 was drilled to test the interpreted down-dip continuation of these intersections. The hole encountered pyrrhotite mineralization and several small faults however, the current interpretation suggests that it may have terminated before reaching the projected target. Assays for hole EME-26-116 are still pending.

Background Geology

The 1500 Zone contains copper, zinc, gold, silver and lead grades comparable to those of the main Errington Deposit and is interpreted as an extension along the Vermilion horizon. The Christie Fault is interpreted to extend eastward from Errington Main toward the 1500 Zone; however, additional faults are expected and have not yet been sufficiently mapped. This structural complexity limits the current understanding of how the mineralized centres across the entire Errington Deposit are related to one another up dip, down dip and along an easterly plunge. Copper and zinc mineralization also occurs at surface nearby and may represent a fault-displaced repetition of the 1500 Zone sequence, potentially forming part of a separate mineralized centre.

Historical drilling at the 1500 Zone is limited. The zone has been modelled as two areas: a copper-enriched western portion and an eastern portion, with the western mineralization interpreted as a separate continuous zone. Drill spacing remains relatively wide, and portions of the interpreted mineralized envelope lie outside the optimized shapes used to report the 2026 mineral resource estimate (Figure 3). Further drilling and modelling are required to determine whether additional mineral resources can be defined in these areas. In addition, historical holes east of the 1500 Zone intersected massive sulphide mineralization that has not been followed up.

The 1500 Zone forms part of the Errington deposit mineral resource estimate, effective September 20, 2026. The Company announced that estimate in its September 22, 2026 news release titled "Errington Metals Announces Maiden Mineral Resource Estimate for the Sudbury Basin Project."

The Company plans to complete downhole electromagnetic surveys in accessible drill holes at the 1500 Zone to identify conductive responses that may indicate off-hole sulphide mineralization. Survey results and the updated structural interpretation will help guide follow-up drilling during Phase 2. Drilling will be required to determine the source, extent and grade of any mineralization associated with these responses.

Note: Reported intervals are downhole lengths. True widths have not been estimated but are within 70-100% of the drill width based on the drill hole design and downhole deviation surveys. Reported grades are weighted average composites directly from the sample lengths and assay results.

CuEq (%) = Cu (%) + 0.1804 × Zn (%) + 0.0731 × Pb (%) + 0.5321 × Au (g/t) + 0.006124 × Ag (g/t). Assumed metal prices are US$5.80/lb copper, US$1.30/lb zinc, US$0.90/lb lead, US$4,100/oz gold and US$50/oz silver. Assumed recoveries are 72% copper, 78% zinc, 45% lead, 70% gold and 70% silver.

Assay results from other holes drilled at 1500 Zone are pending.

Future Plans

The Company has initiated its Phase 2 drill campaign of approximately 55,000 m with initial drilling focused on testing the extensions of the Vermilion deposit and some infill drilling to continue to improve the resource model. The program will expand to test target areas identified in the Errington and Balfour mineral resource models and to further understand their expansion potential. Regional targets based on geological and geophysical data interpretation have been identified and will also be tested. Further drilling to collect a bulk sample at Errington will be conducted this fall in preparation for a mini-pilot metallurgical study next year.
