PORPHYRY COPPER-GOLD MINERALIZATION EXTENDED AT COWTRAIL PROJECT, BRITISH COLUMBIA

BRS Resources Ltd. and Cariboo Rose Resources Ltd. have released results from a four-hole, 1,138-metre diamond drill program completed in August, 2025, at the Cowtrail project in south-central British Columbia.

Cowtrail is a 100-per-cent-Cariboo-Rose-owned, 4,717-hectare porphyry copper-gold project contiguous with the Woodjam copper-gold porphyry project owned by Vizsla Copper Corp. The 2025 program targeted the Lea Lake zone, a southwest-trending mineralized corridor associated with historic induced polarization anomalies and coincident magnetic features extending beyond the original 2007 discovery intercept.

Results confirm the continuation of porphyry-style copper-gold mineralization, which remains open along strike and at depth.

Copper equivalent (CuEq) values represent the combined value of copper and gold in one tonne of rock divided by the value of copper in one tonne grading 1.0 per cent copper, using metal prices of $4.50 (U.S.) per pound copper and $3,500 (U.S.) per ounce gold, without consideration for metallurgical recoveries. Historic drilling and geophysics define a coherent southwest-trending mineralized vector extending beyond the 2007 discovery hole. Previous significant intercepts include 0.15 per cent copper and 0.12 gram per tonne gold over 105.0 metres (CT23-16 (2023)), 0.17 per cent copper and 0.11 gram per tonne gold over 40.0 metres (CT2011-12 (2011)) and 1.16 grams per tonne gold over 18.3 metres (07-DDH-1 (2007) .

Cowtrail occupies a low-elevation, flat, coniferous-tree-covered landscape (much of it logged). Outcrop is very limited (probably less than 1 per cent of the total area). A series of stocks, dikes and plugs are confirmed by drilling over an area measuring approximately three kilometres by two kilometres by drill holes targeting induced polarization anomalies. These intrusive bodies include, diorite, syenite, quartz, monzonite and quartz feldspar porphyry. Many induced polarization anomalies have not yet been drilled.

An unpublished 1991 Cogema Canada Ltd. report documented mineralized biotite, diorite and monzodiorite float associated with a strong circular total magnetic intensity (TMI) anomaly several hundred metres farther along this same trend, indicating additional untested potential within the corridor.

Cowtrail has been under option to BRS Resources since 2022. BRS may earn a 60-per-cent interest by completing $2-million in exploration expenditures, making $200,000 in cash payments and issuing shares equivalent to $200,000 by Dec. 19, 2027.

Analyses were performed by MSALABS of Langley, B.C., using ICP multielement analysis and 30-gram fire assay. Standards and blanks were inserted by the company and additional samples by the laboratory and sampling was conducted at approximately three-metre intervals. Recoveries were generally greater than 85 per cent. Sample results were verified by the qualified person by comparing results from the standards against their posted values. The assay lab completing the work, MSALABS, is completely independent from BRS Resources or Cariboo Rose Resources. Drill core, 4.5 centimetres in diameter, was cut longitudinally using a diamond-tipped saw, with one-half going into the sample bag and half kept for future work.

J.W. (Bill) Morton, PGeo, a director of Cariboo Rose Resources and a qualified person under National Instrument 43-101, has reviewed and approved the technical content of this release.
