BRS Resources Announces 220.9 m Grading 0.30% Copper Equivalent Including 43 Meters Grading 0.57% Copper Eq Intersected at Cowtrail

Deep drilling at Cowtrail reveals broad copper-gold intervals but economic potential remains untested.

What the company is saying

Cariboo Rose Resources Ltd. (TSXV: CRB) and BRS Resources Ltd. (CSE: BRS) report results from a four-hole, 1,275-meter diamond drill program completed in July 2026 at the Cowtrail Project in British Columbia. The companies emphasize the continuity of porphyry copper-gold mineralization, highlighting that mineralization in hole CT26-28 continues to the bottom of the hole, with the last sample grading 0.21% copper and 0.11 g/t gold (0.32% Cu Eq). They frame Cowtrail as a large, 4,717-hectare project adjacent to other known copper-gold systems and stress that mineralization remains open along strike and to depth. The technical disclosure is detailed, with explicit grades, intervals, and sampling protocols, but the narrative is careful to note that true widths are unknown and no metallurgical work has been done at Cowtrail. Price assumptions of $5.50 per pound copper and $4,000 per ounce gold, along with recovery rates of 83% for copper and 77% for gold, are taken from the nearby Mount Polley Mine. J.W. (Bill) Morton, P.Geo., a director of BRS and Qualified Person under NI 43-101, has reviewed and approved the technical content, lending regulatory credibility to the release.

What the data suggests

The drilling program totaled 1,275 meters across four holes, with significant mineralization encountered only in CT26-26A and CT26-28. CT26-28, the first deep test at Cowtrail, returned 220.9 meters grading 0.19% copper and 0.11 g/t gold (0.30% CuEq), including 163.9 meters at 0.22% copper and 0.13 g/t gold (0.35% CuEq), and a higher-grade 43.0-meter interval at 0.34% copper and 0.23 g/t gold (0.57% CuEq). The last sample at the bottom of CT26-28 graded 0.21% copper and 0.11 g/t gold (0.32% CuEq), indicating mineralization is open at depth. CT26-26A intersected 39.0 meters at 0.03% copper and 0.17 g/t gold (0.20% CuEq). Holes CT26-25 and CT26-27 did not yield significant intercepts. All copper equivalent calculations use $5.50/lb copper and $4,000/oz gold with assumed recoveries of 83% for copper and 77% for gold, but these are not based on Cowtrail-specific metallurgy. No resource estimate, economic assessment, or true width calculation is provided. The technical data is robust for an early-stage program, but the economic significance of the mineralization remains undetermined.

Analysis

The announcement is a factual technical update on the results of a 2026 diamond drill program at the Cowtrail Project in British Columbia. The majority of claims are realised and supported by specific drill intercepts, grades, and intervals, with sampling and QA/QC protocols clearly described. Only a small fraction of the language is forward-looking, such as the mineralization 'remaining open along strike and to depth' and the potential for reentering and deepening a drill hole. There is no promotional or exaggerated language, and the technical results are presented with appropriate caveats (e.g., no metallurgical work completed, true widths unknown). No large capital outlay or economic study is disclosed, and there are no claims of imminent production or economic value. The absence of resource estimates or economic analysis is normal for an exploration-stage update and does not constitute a deficiency. Overall, the tone is proportionate to the evidence, with no hype detected.

Risk flags

• ●The absence of Cowtrail-specific metallurgical testing means that all recovery and copper equivalent calculations rely on assumptions from the nearby Mount Polley Mine, which may not be representative. This introduces uncertainty about the actual recoverability and economic value of the mineralization.
• ●True widths of the reported intercepts are unknown, so the actual thickness and geometry of the mineralized zones remain unconfirmed. This limits the ability to assess the scale and continuity of the deposit.
• ●Only two of four holes returned significant mineralization, and the best grades are moderate for porphyry systems. Without a resource estimate or economic study, there is no basis for assessing the project's potential profitability or development timeline.

Bottom line

This update confirms the presence of broad, moderate-grade copper-gold mineralization at depth in the Cowtrail Project, with the most promising interval being 220.9 meters at 0.19% copper and 0.11 g/t gold (0.30% CuEq) in hole CT26-28. However, the lack of Cowtrail-specific metallurgical data, unknown true widths, and the absence of a resource estimate mean that the economic significance remains speculative. The technical disclosure is thorough for this stage, but investors should recognize that these results are an early step in a multi-year exploration process. The most important takeaway is that Cowtrail remains a geologically interesting but unproven asset, and future value will depend on follow-up drilling, metallurgical work, and eventual resource definition. Watch for updates on deeper drilling, metallurgical test results, and the first resource estimate to clarify the project's development potential.

Announcement summary

(TSXV: CRB) Cariboo Rose Resources Ltd. and (CSE: BRS) BRS Resources Ltd. announced results from a four-hole, 1,275-meter diamond drill program completed in July 2026 at the Cowtrail Project in south-central British Columbia near Williams Lake. The Cowtrail Project is a 4,717-hectare porphyry copper-gold property contiguous with the Woodjam and Redgold copper-gold porphyry projects owned by Vizsla Copper Corp. The project is situated in Upper Triassic rocks of the Quesnel Terrane, which also host the Mount Polley, Afton, and Copper Mountain Mines. The 2026 drilling confirms the continuation of porphyry copper-gold mineralization previously drilled in 2023 and 2025, with mineralization remaining open along strike and to depth. Hole CT26-28, the first deep test of the Cowtrail project, continued to the bottom of the hole, with the last sample grading 0.21% copper and 0.11 g/t gold (0.32% Cu Eq). Drill casing for CT26-28 was left in place for potential reentry and deepening. Holes CT26-25 and CT26-27 did not return significant intercepts. Significant 2026 drill results include: CT26-26A from 133.0 to 172.0 meters (39.0 meters) grading 0.03% copper, 0.17 g/t gold, and 0.20% CuEq; CT26-28 from 338.0 to 558.9 meters (220.9 meters) grading 0.19% copper, 0.11 g/t gold, and 0.30% CuEq; including 395.0 to 558.9 meters (163.9 meters) at 0.22% copper, 0.13 g/t gold, and 0.35% CuEq; and 425.0 to 468.0 meters (43.0 meters) at 0.34% copper, 0.23 g/t gold, and 0.57% CuEq. Assumed recoveries are 83% for copper and 77% for gold, based on published reports for the nearby Mount Polley Mine operated by Imperial Metals Corp. Price assumptions are $5.50 per pound for copper and $4,000 per ounce for gold. No metallurgical work has been completed specifically at Cowtrail and true widths remain unknown. Hole details include: CT26-25 (end of hole at 57.0 m), CT26-26A (352.0 m), CT26-27 (306.9 m), and CT26-28 (558.9 m). Drill core was cut and sampled in 2- or 3-meter increments, with analyses performed by MSALABS of Langley, BC, using a 30-gram fire assay for gold and ICP-ES for multi-elements including copper. Laboratory protocols included blanks, standards, and duplicate re-assays. J.W. (Bill) Morton, P.Geo., a director of BRS and Qualified Person under NI 43-101, reviewed and approved the technical content of the release. Byron Coulthard is President and CEO of BRS Resources Ltd.
