Cowtrail Copper-Gold Project: 2026 Drilling & Geophysics Program

Updated June 3, 2026 — Vancouver, British Columbia

Vancouver, British Columbia — BRS Resources Ltd. (CSE: BRS), together with partner Cariboo Rose Resources Ltd. (TSXV: CRB), has advanced the Cowtrail Copper-Gold Porphyry Project in south-central British Columbia through a phased 2026 field program combining airborne geophysics and diamond drilling. Cowtrail comprises 4,717 hectares contiguous with Vizsla Copper Corp.'s Woodjam and Redgold projects, approximately 20 kilometres southeast of Imperial Metals' operating Mount Polley Mine.

Program Timeline

April 16, 2026

BRS and Cariboo Rose Resources announce the 2026 exploration plan for Cowtrail, targeting the Lea Lake area with 1,500–2,000 metres of diamond drilling. The release highlights prior intercepts of 0.15% Cu and 0.12 g/t Au over 105.0 metres (hole CT23-16, drilled 2023) and 0.20% Cu and 0.10 g/t Au over 70.0 metres (hole CT25-23, drilled 2025), with further land-based or airborne geophysics planned.

May 13, 2026

Precision GeoSurveys of Langley, BC is engaged to fly a helicopter-borne high-resolution aeromagnetic, radiometric and VLF survey over a 27 km² core area at 100-metre line spacing. Paradigm Diamond Drilling of Kamloops, BC is retained to complete 1,500 metres of drilling on targets identified in 2023 and 2025.

May 27, 2026

The airborne geophysical survey is completed. Data processing begins, targeting magnetic highs indicative of new porphyry centres and magnetic lows consistent with pyrite destruction from hydrothermal circulation.

June 3, 2026

Diamond drilling commences on copper-gold porphyry targets identified through prior exploration and the newly completed airborne survey. J.W. (Bill) Morton, P.Geo., a director of BRS and Qualified Person under NI 43-101, has reviewed and approved the technical content of the program.

About the Project

Cowtrail sits within BC's Quesnel Trough — Canada's most productive copper-gold metallogenic belt — and shares significant geological similarities with the neighbouring Mount Polley deposit. Results from the 2026 program will be released as they are reviewed, in accordance with the companies' disclosure policies.
