Selkirk Copper Upgrades to the OTCQX Best Market

Selkirk Copper Mines has qualified to graduate from the OTCQB Venture Market to the OTCQX Best Market, effective July 28, 2026, with its common shares continuing to trade under the ticker SKRKF. The shares also continue to trade on the TSX Venture Exchange under SCMI and on the Frankfurt Stock Exchange under IO20. The upgrade coincides with the company's work to advance the former Minto copper-gold-silver mine in Yukon toward a restart decision in 2027.

Company Overview

Selkirk Copper Mines (TSXV: SCMI | OTCQB: SKRKF | FRA: IO20) is advancing the restart and redevelopment of the former Minto copper-gold-silver mine in Yukon, Canada, in partnership with the Selkirk First Nation, which holds a controlling interest in the company. Selkirk Copper controls 26,850 hectares of mineral claims in the Minto-Carmacks copper belt, along with existing open-pit and underground infrastructure, including a 4,100-tonne-per-day processing plant and a 400-person camp.

Upgrade to the OTCQX Best Market

Effective July 28, 2026, Selkirk Copper qualified to move its US listing from the OTCQB Venture Market to the OTCQX Best Market. The common shares continue to trade under the same ticker, SKRKF, so the change alters the market tier rather than the trading symbol.

The OTCQX Best Market is the highest tier of the OTC Markets in the United States and is designed for established, investor-focused US and international companies. Qualifying companies must meet high financial standards, follow best-practice corporate governance, and demonstrate compliance with applicable securities laws. Graduating from the OTCQB Market to OTCQX is positioned by the company as a milestone that builds visibility among US investors.

President and Chief Executive Officer of Selkirk Copper Mines, M. Colin Joudrie, links the upgrade to the company's development timeline:

"This progression enhances our visibility among U.S. investors, improves liquidity, and reinforces our commitment to creating long-term shareholder value as we advance the Minto copper-gold-silver mine toward a restart decision in 2027."

Continued Listings & US Investor Access

Alongside the OTCQX listing, Selkirk Copper's common shares continue to trade on the TSX Venture Exchange in Canada under SCMI and on the Frankfurt Stock Exchange under IO20, maintaining the company's existing global exposure. US investors can access current financial disclosure and Real-Time Level 2 quotes through the OTC Markets website.

Next Steps

Selkirk Copper is completing the remainder of its drill programme and integrating the results into ongoing trade-off studies as it works toward a restart decision on the Minto copper-gold-silver mine in 2027.
