Assaying Underway at Cowtrail and Lightning Strike

Cariboo Rose Resources Ltd. (CRB) provided a progress update on its 2026 exploration programs at the Cowtrail Copper-Gold Project and the Lightning Strike Gold-Silver Project. At Cowtrail, option partner BRS Resources completed a 1,293-meter, four-hole diamond drill program. The final hole was shut down in visible mineralization at 562 meters. Core cutting and sampling are complete, and analytical results are pending.

At Lightning Strike, the company initiated a self-funded 1,062-meter, four-hole drill program. Samples from three holes have been processed and shipped to the lab, with sampling continuing on the fourth hole. No analytical results are available yet. Background updates were provided for the Pat and Carruthers Pass copper projects, noting historical magnetic anomalies and past mineralization, but no new assay results or active drilling were disclosed.

The timeline of recent activity began in May 2026 with an airborne geophysical survey at Cowtrail to prioritize targets. Drilling commenced at both Cowtrail and Lightning Strike in June 2026. By July 2026, the first phase of Cowtrail drilling was completed, totaling 1,293 meters, while drilling at Lightning Strike began. In August 2026, core cutting and sampling were completed at both projects, with samples shipped to MSALabs. As of September 2026, assaying is underway at both projects, with no results released.

Cariboo Rose Resources Ltd. (CRB) has issued a standard operational status update confirming that drilling activities have been completed and samples are currently in the assay pipeline. The announcement contains no new geological data, financial updates, or changes to project economics, and aligns fully with previous expectations set in the July and August 2026 releases.

Because the market had already priced in the drilling completion and sampling phase, the update carries no new information to move the stock. Routine operational updates of this nature typically have a neutral impact on share price, particularly when the company is in the pre-assay phase. The lack of immediate assay results means the catalyst for price appreciation is delayed until actual geological data is released.

Cariboo Rose Resources Ltd. (CRB) is a pre-revenue junior exploration company focused on copper, gold, and silver properties in British Columbia. The company utilizes a hybrid prospect generator model, advancing projects independently while leveraging option agreements with partners to fund exploration and reduce dilution.

The company’s flagship assets include the Cowtrail Copper-Gold Project, a 4,717-hectare porphyry copper-gold property located 20 km southeast of the operating Mount Polley mine. This property is contiguous with Vizsla Copper Corp.'s Woodjam and Redgold projects, and BRS Resources holds an option to earn a 60% interest.

Also central to the portfolio is the Lightning Strike Gold-Silver Project, a 4,193-hectare 100%-owned property located 60 km northeast of 100 Mile House, BC. This site hosts orogenic sediment-hosted gold-silver mineralization with historical high-grade intercepts.

Additional assets include the Pat, Carruthers Pass, CHG, Coquigold, and Koster Dam projects, many of which are under option or joint venture agreements.
