Porphyry Copper-Gold Mineralization Extended at

Cowtrail Project, British Columbia

Lea Lake Zone Drilling Confirms Continuity of Southwest-Trending Corridor

Vancouver, BC – December 1, 2025 – BRS Resources Ltd. (TSX-V: BRS) and Cariboo Rose Resources

Ltd. (TSX-V: CRB) announce results from a four-hole, 1,138-metre diamond drill program

completed in August 2025 at the Cowtrail Project, south-central British Columbia.

Cowtrail is a 100% Cariboo Rose-owned, 4,717-hectare porphyry copper-gold project contiguous

with the Woodjam copper-gold porphyry project owned by Vizsla Copper Corp. (TSX-V: VCU). 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.

2025 Drill Results

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% copper, using metal prices of US$4.50/lb copper and

US$3,500/oz gold, without consideration for metallurgical recoveries.

Plan and cross-section diagrams accompanying this release illustrate all drill holes completed in the

2025 program. Drill traces and mineralized intervals are shown in full on both views.

Historic drilling and geophysics define a coherent southwest-trending mineralized vector extending

beyond the 2007 discovery hole. Previous significant intercepts include 0.15% Cu and 0.12 g/t Au

over 105.0 m (CT23-16[2023]), 0.17% Cu and 0.11 g/t Au over 40.0 m (CT2011-12[2011]), and

1.16 g/t Au over 18.3 m (07-DDH-1[2007]).

Cowtrail occupies a low elevation, flat, coniferous tree covered landscape (much of it logged). Outcrop

is very limited (probably <1% of the total area). A series of stocks, dikes and plugs are confirmed by

drilling over an area measuring approximately 3 kilometres by 2 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An unpublished 1991 Cogema Canada Ltd.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 further along this same trend, indicating additional untested potential within the

corridor.

Cowtrail has been under option to BRS Resources Ltd. since 2022. BRS may earn a 60% interest by

completing $2,000,000 in exploration expenditures, making $200,000 in cash payments, and

issuing shares equivalent to $200,000 by December 19, 2027.

Analyses were performed by MSALABS of Langley, BC using ICP multi-element 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 3-metre intervals. Recoveries were generally

>85%. 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 cm in diameter, was cut longitudinally

using a diamond tipped saw with one half going into the sample bag and half kept for future work.
