Lea Lake Zone Drilling Confirms Continuity of Southwest-Trending Corridor

Vancouver, BC – December 1, 2025 – TheNewswire - 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.

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An unpublished 1991 Cogema Canada Ltd.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.
