Green Bridge Metals Receives Approval for Drilling at Serpentine Project

Green Bridge Metals Corporation has announced approval from the Minnesota Department of Natural Resources for its exploration plan at the Serpentine Copper-Nickel Project in Minnesota. The company has selected Foraco International to conduct a minimum of 1,640 meters of diamond core drilling for Phase 1 of the project.

This development highlights a critical step forward for Green Bridge Metals in advancing the Serpentine project, which is located within a key copper-nickel-platinum group elements system. CEO David Suda remarked on the importance of disciplined technical work in mineral development, focusing on reducing uncertainty and increasing confidence in resources.

The project contains significant inferred and indicated mineral resources, with current estimates including 279.9 million tonnes of inferred mineral resources and 21.6 million tonnes of indicated resources. The upcoming drilling aims to expand geological confidence and support future resource updates.

Drilling will commence in August 2026, with additional metallurgical testing planned to understand processing characteristics better. The project aligns with U.S. priorities for domestic sources of critical minerals, and Green Bridge Metals continues to collaborate with regulators and stakeholders to uphold responsible exploration practices.
