Green Bridge Metals Corp. (GRBM:CSE; GBMCF:OTC; J48:FWB) announced that it has received approval of its exploration plan from the Minnesota Department of Natural Resources for its Serpentine Copper-Nickel Project in St. Louis County, Minnesota. The company also selected Foraco International to conduct a minimum of 1,640 meters of diamond core drilling as part of the project's planned Phase 1 exploration program.
According to the company, Foraco will mobilize to the site to execute the drilling program, building on its ongoing work at Green Bridge's Titac Project. The Phase 1 program is designed to target high-priority zones within the Serpentine copper-nickel-platinum group elements system.
CEO David Suda said in a company news release, "We are excited to secure the DNR approval and select Foraco once again to commence our Phase 1 drilling at Serpentine. Serpentine already hosts significant Inferred Mineral Resources and Indicated Mineral Resources within one of North America's premier copper-nickel districts. Our objective is to systematically advance the project through additional drilling, resource refinement, and metallurgical work designed to improve our understanding of the deposit and support future technical studies."
As disclosed in the technical report entitled "Technical Report and Mineral Resource Estimate for the Serpentine Project, St. Louis County, Minnesota, USA," with an effective date of July 14, 2025, Serpentine hosts an Inferred Mineral Resource Estimate of 279.9 million tonnes grading 0.37% copper, 0.12% nickel and 0.007% cobalt using a US$10.25 per tonne net smelter return cutoff. The resource includes 21.6 million tonnes in the Indicated Mineral Resource category, grading 0.46% copper, 0.16% nickel, and 0.014% cobalt using the same US$10.25 per tonne net smelter return cutoff.
The company said the approved Phase 1 program is expected to begin in August 2026. Drilling will focus on areas where additional data may support increased geological confidence in portions of the existing mineral resource. In parallel, Green Bridge plans to undertake metallurgical test work to better understand potential processing characteristics and recovery pathways. The company stated that the objective is to expand the technical dataset, support future resource updates where warranted, and position the project for future scoping-level studies, subject to results.
Green Bridge also said drilling is expected to test and expand known mineralization, with results intended to inform future resource updates and development planning. The company added that it continues to work with regulators and stakeholders to support responsible exploration practices.
Copper Market Navigates Economic and Policy Crosscurrents
Yahoo Finance reported on July 3 that uncertainty surrounding U.S. trade policy had become a more immediate influence on copper markets than shipping disruptions in the Strait of Hormuz. The publication wrote that "copper's real swing factor now sits in Washington, not the Gulf," noting that a review of the domestic refined copper market had been submitted to the U.S. administration while market participants awaited a decision on potential import tariffs.
BNP Paribas metals strategist David Wilson told Yahoo Finance that opponents of the proposal were "still actively and significantly lobbying to not have a tariff," indicating that the outcome had remained uncertain. Yahoo Finance also quoted Vandana Hari of Vanda Insights, who said the Strait of Hormuz "continues to reopen but it's patchy, unpredictable, and not fully transparent," while noting that copper would continue to trade on its own supply and demand fundamentals alongside policy developments.
Trading Economics reported on July 4 that copper futures had climbed toward US$6.20 per pound and were on track for a weekly gain as traders reduced expectations for additional U.S. Federal Reserve interest rate hikes following weaker-than-expected June employment data. The publication wrote that industrial metals had previously faced pressure as Federal Reserve officials had signaled a greater willingness to tighten monetary policy, while easing supply risks as commercial traffic through the Strait of Hormuz improved had also weighed on prices. Trading Economics described copper as "one of the most widely used industrial metals in the world" and stated that it played "a critical role in construction, electronics, power generation, and renewable energy systems," making its price sensitive to changes in industrial demand and economic growth. It also noted that Chile accounted for the largest share of global copper mining, followed by the Democratic Republic of the Congo, Peru, China, and the United States.
In a July 5 market outlook, Power Hedge wrote that "the long-term commodity bull thesis remained intact," adding that "copper miners and diversified mining companies may outperform as AI-driven demand outpaces supply growth." The report also stated that the 2026 oil price surge, driven by Middle East hostilities and disruption in the Strait of Hormuz, had "reignited inflation and altered macro outlooks." According to the analysis, persistently elevated inflation, supported by higher energy costs and semiconductor shortages, had constrained the Federal Reserve to modest rate hikes rather than interest rate cuts. The report also noted that crude oil had been used throughout the economy, including in mining equipment used to produce metals, contributing to higher production costs across multiple industries.
Analyst Commentary Focuses on Copper and Titanium Potential
In a March 26 contributed opinion, Michael Ballanger of GGM Advisory Inc. revisited Green Bridge Metals after the firm initiated coverage following its participation in a November financing that included units priced at CA$0.09 with a CA$0.12 half-warrant and CA$0.12 with a CA$0.15 half-warrant. Ballanger noted that the shares had later closed at CA$0.23 and wrote, "I really like this company and see a bright future for it."
Writing about the company's drilling program, Ballanger said that "the presence of ilmenite in core samples increases the likelihood of a significant titanium component, which is important." He described titanium as a silver-white transition metal that was as strong as steel while being nearly 45% lighter. He added that the metal's corrosion resistance and biocompatibility had led to its use in applications including jet engines, airframes, spacecraft, dental implants, joint replacements, surgical instruments, desalination facilities, chemical processing equipment, and marine infrastructure.
Ballanger returned to the copper market in an April 27 update, where he listed Green Bridge Metals among the junior copper companies held in GGM Advisory portfolios. Discussing the broader market, he wrote that "there is no bullish case that ever holds a candle against copper when it comes to the certainty of outcome," citing mine closures, production disruptions, and declining output from major operations as factors affecting supply.
He also wrote that governments would be "forced to eliminate roadblocks that delay new exploration and development, which will favor the junior copper group far more than their senior counterparts." Ballanger said this was "one of the main reasons why juniors like ... Green Bridge Metals Corp. ... are held in the GGMA portfolios with such overweight positioning." He added that "the senior miners are too busy with their existing operations to focus on greenfield exploration programs, which is why most, if not all, of the major new copper discoveries are made by the juniors."

Planned Work Program and Project Milestones
According to the company's June 2026 corporate presentation, the Serpentine project's pre-feasibility pathway includes exploration drilling during Q2 and Q3 2026, followed by a planned 25,500-meter infill core drilling program, installation of water monitoring wells, metallurgical studies, and engineering and environmental work. The presentation also notes preliminary 2012 metallurgical work that indicated strong recoveries of copper and nickel and states that the project is situated in an established mining jurisdiction with neighboring railways, roadways, processing facilities, and other infrastructure.
The presentation also outlines project objectives that include upgrading mineral resources from the Inferred category to the Indicated category, increasing overall copper equivalent grade by expanding the known high-grade horizon, incorporating platinum group element assays into future resource models, conducting metallurgical testing, optimizing the project's low strip ratio, targeting a Preliminary Economic Assessment in 2027, and a Pre-Feasibility Study in 2029.
In addition, the June 2026 corporate presentation states that eight diamond core drill holes are planned and permitted at Serpentine as the initial component of a larger infill drilling program that is expected to include 140 drill holes. It also notes that the project has been permitted by the Minnesota Department of Natural Resources to drill twelve diamond core holes during 2026. The presentation states that the company is engaging local consulting groups to conduct environmental, biological, and archeological surveys at Serpentine, has engaged Barr Engineering for environmental consulting and ESG surveys related to a scoping study, and is working with local public relations groups in Minnesota to support community transparency. The company also states that historical core resampling was completed in February 2026, an integrated EM-geology targeting model has been established, and evaluation of an initial step-out drilling program is underway.
