THUNDER BAY, ON, May 4, 2026 /CNW/ - Errington Metals Corp. (TSXV: EM) ("Errington" or the "Company") is pleased to share results from its 2025 drilling program at the Errington mineralized zone, part of the Company's Sudbury Basin Project. The program was designed to better define the size and shape of the mineralized zones in order to support a future mineral resource estimate.
Highlights
"These results are an important step in tightening our geological model at Errington," stated Frank Santaguida, Vice President, Exploration of Errington Metals. "The 2025 program combined targeted step-outs and local infill to improve our confidence in continuity, clarify key structural controls such as the Christie Fault, and to better define the styles of mineralization that relate to higher grades and potentially define our ore types. This work will feed directly into current 3D modelling and our planned mineral resource estimate in H2 2026."

The Program
In late 2025, Errington completed a diamond drilling program at the Errington mineralized zone (See Figure 1) to validate historic work and refine geological interpretations for a new mineral resource estimate. Assays for this drilling are reported in Table 1 below
The drill program included 16 diamond drill holes totaling 4,172 metres. Drilling focused on areas with relatively limited historic drilling (see Figure 2), especially where previous geological interpretations constrained the mineralized zone.

Previous surface drilling largely confirmed mineralization known from historic underground work; however, some areas had limited drill density and key structural features (faults and folds) were not fully constrained, leaving parts of the system under-tested. The 2025 program targeted these gaps with holes aimed at better defining the structural geometry and continuity of the mineralized zones. Several examples of this opportunity exist, including the upper part of the Errington zone, where the mineralized horizon is folded. Several areas near the fold hinge had not been drilled, creating an opportunity to expand the interpreted mineralized footprint. In addition, some historic drilling was completed down-dip, which minimizes the zone's true thickness in places; the 2025 drilling helps address this by testing across the horizon from south to north.
The program intersected several thicker mineralized intervals, strengthening the dataset for 3D geological interpretation and future resource modelling (see representative Sections 1 to 3 below). Drilling also improved the Company's understanding of displacement along the Christie Fault, which offsets the mineralized horizon. Drilling remains relatively sparse north of the Christie Fault, however mineralized intersections in historic drill holes highlight additional targets for follow-up.
In several holes, the Company intersected copper and gold-rich mineralization as chalcopyrite stringers and bands (typically associated with feeder-style mineralization in VMS-type deposits) that appear to continue for more than 100 metres along strike. Elsewhere, higher copper values occur within the zinc-rich massive sulphide mineralization, highlighting the polymetallic nature of the system and multiple mineralization styles that may reflect different ore types for mining and processing.
The drilling also intersected zones of massive pyrite with lower base-metal grades but containing elevated gold and silver. These zones occur adjacent to the copper-zinc-lead massive sulphides and may reflect metal zonation within the broader VMS system. This gold-silver style of mineralization was not a main focus of earlier work and could represent additional upside for expanding known zones, defining new target areas, and metallurgical optimization and planning.
The Background and History
Errington is one of three mineralized centres within the Company's Sudbury Basin Project. Mineralization at all three is stratabound and widely considered to be Volcanogenic Massive Sulphide type -- a deposit type that commonly forms as sulphide lenses and associated stringer zones within volcanic rocks and can host copper and zinc, with meaningful gold and silver credits.
Glencore prepared a historical mineral resource estimate for Errington and Vermilion in 2013 and reported updated historical estimates annually through 2024, as summarized in Table 2. A "qualified person" (as defined in National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101") has not done sufficient work to classify the historical estimate as current mineral resources, and Errington is not treating the historical estimate as current mineral resources. See notes to table 2 below.
Errington Metals has evaluated the data used for the historical resource estimate and has published a Technical Report titled "Technical Report – Sudbury Basin Project" dated April 2, 2026. No mineral reserve estimates have been made publicly available for the Errington and Vermilion deposits.

Notes: |
|
1. |
The current QP notes that while this historical Mineral Resource Estimate appears to have generally followed the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Definitions Standards for Mineral Resources and Mineral Reserves in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects, not all aspects of the estimation procedures and related parameters have been reliably verified at the time of writing. However, this estimate is considered relevant as it provides an indication of the distribution and grade of mineralization at the Errington and Vermilion deposits and will help guide future exploration. |
2. |
Mineral resources that are not mineral reserves do not have demonstrated economic viability. |
3. |
Inferred Mineral Resources are exclusive of the Measured and Indicated Resources. |
4. |
Details on underground mining stope optimization are not currently available. |
5. |
Exact details on the modifying factors used to develop the resource stope shapes for reporting purposes are presently unknown; however, resource categories were assigned based on a Net Smelter Return (NSR) equivalent value based on Glencore's long-term pricing forecasts, using a cut-off of US$25 and the following formula: NSR = 10.64 * % Zn + 50.52 * % Cu + 4.74 * % Pb + 0.59 * g/t Ag + 33.12 * g/t Au. |
6. |
Underground resources were reported using a cut-off grade of 1.0% Zn. |
7. |
Resource estimations were interpolated using Inverse Distance Weighting (IDW2). |
8. |
The effective date of the historical Mineral Resource Estimate is December 31, 2024. |
9. |
The current QP is not aware of any metallurgical, environmental, permitting, title, legal, taxation, socio-economic, marketing, political, or other risk factors that might materially affect the historical Mineral Resources Estimate presented herein. |
10. |
Figures have been rounded to an appropriate level of precision for the reporting of Mineral Resources; as a result, totals may not compute exactly as shown. |
11. |
Additional work required to verify the estimate includes (but is not limited to) additional confirmation drilling, independent QP sampling and drill collar verification checks, continued review of previous interpreted geological and mineralization models, continued validation of historical estimation methodology and related input parameters, review of the underground resource stope optimization and depletion procedures, preliminary geotechnical assessment, etc. |
12. |
The historical Mineral Resource Estimate reported herein has been sourced from Glencore's 2024 Mineral Resource Estimate (MRE) and Mineral Reserve Estimate Report (Glencore, 2024). |
At Errington, mineralization occurs as sulphide minerals that contain copper, zinc, lead, gold, and silver. The minerals occur in different styles and levels within the system. At Errington, higher copper and gold grades occur both within massive sulphide intervals, locally comprising more than 60% sulphide minerals, and within stringer-style or feeder-style mineralization. (see pictures 1 & 2 below). Ongoing mineralogy and metallurgy studies from the Errington mineralized zone are intended to better understand metal distribution, key sulphide minerals, and implications for future processing.
The Errington mineralized centre includes three main zones -- Main, West, and 1500 -- which are interpreted to represent discrete offset segments of the same mineralized horizon.
Folding and faulting have shifted and repeated parts of the rock sequence at Errington, which have displaced the mineralized horizon. One important structure, the Christie Fault, offsets part of the Errington Main Zone. Constraining the extent of this offset is important for targeting potential repetitions or extensions of mineralization on either side of the fault.
