OTC Markets Group Welcomes Grande Portage Resources Ltd. to OTCQX

Grande Portage Resources Ltd. has successfully upgraded its U.S. trading status from the OTCQB® Venture Market to the OTCQX® Best Market, effective May 11, 2026. The company begins trading under the symbol "GPTRF". This upgrade signifies that Grande Portage has met higher financial standards and demonstrated compliance with applicable securities laws and best practice corporate governance. The move is intended to increase visibility and accessibility for U.S. investors as the company advances its New Amalga Gold deposit in Southeast Alaska.

The OTCQX upgrade is a positive regulatory milestone that validates the company's financial health and governance standards, likely improving liquidity and access to institutional capital in the United States. However, this news is largely incremental relative to the fundamental catalysts released earlier in 2026. The Preliminary Economic Assessment (PEA) filed on April 15, 2026, which projected a $721M after-tax NPV and 56% IRR, was the primary value driver. Additionally, the Eric Sprott financing of C$5 million in December 2025 provided significant balance sheet strength. The OTCQX upgrade confirms these fundamentals are recognized by market regulators but does not alter the project economics or resource base directly. Given that the PEA and major financing were recent material events, this listing update is viewed as a procedural confirmation rather than a new valuation catalyst.

Grande Portage Resources Ltd. is focused on 100% interest in the New Amalga Gold Project located approximately 25km north of Juneau in Southeast Alaska. The project features a high-grade resource base with an Indicated Resource of 1,438,500 oz Au @ 9.47 g/t and Inferred Resource of 515,700 oz Au @ 8.85 g/t (effective July 2024). The development strategy utilizes a small-footprint underground mining model with third-party offsite processing to eliminate the need for an onsite mill or tailings storage facility.
