Errington Metals Corp Reports Results Of 2025 Drilling Program At Errington Mineralized Zone
Errington Metals Corp. shared 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. The Errington mineralized zone remains open along strike and at depth (down-dip) with priority areas identified for follow-up exploration drilling. Multiple holes intersected copper- and gold-rich stringer mineralization, as well as elevated copper values within zinc-rich massive sulphide intervals. Key Significant Drill Intercepts from 2025 drill program include: 23.8 m grading 3.98% Cu, 5.76% Zn, 1.64% Pb, 2.61 g/t Au and 130.2 g/t Ag in EME-25-035; 24.4 m grading 1.65% Cu, 3.43% Zn, 1.84% Pb, 1.26 g/t Au and 105.7 g/t Ag in EME-25-029; 33.2 m grading 1.43% Cu, 4.30% Zn, 0.97% Pb, 1.41 g/t Au and 59.7 g/t Ag in EME-25-030; 31.8 m grading 1.32% Cu, 2.44 % Zn, %1.76 Pb, 0.34 g/t Au and 77.0 g/t Ag in EME-25-045. Extensions to mineralization were found in areas with limited historic drilling. Results improve confidence in the continuity of mineralization and will feed into 3D geological modelling and an updated mineral resource estimate targeted for the second half of 2026. In late 2025, Errington completed a diamond drilling program at the Errington mineralized zone to validate historic work and refine geological interpretations for a new mineral resource estimate. Assays for this drilling are reported in Table 1. The drill program included 16 diamond drill holes totaling 4,172 metres. Drilling focused on areas with relatively limited historic drilling, especially where previous geological interpretations constrained the mineralized zone. The program intersected several thicker mineralized intervals, strengthening the dataset for 3D geological interpretation and future resource modelling. 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. 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. 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. 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. 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.
