Green Bridge Metals Sets 18-Month PEA Target as Copper Market Tightens

Green Bridge Metals targets a PEA for its Serpentine project within 18 months, launching an expanded drilling campaign to assess copper, nickel, PGMs, and cobalt amid a forecasted global copper shortage.

The copper market's structural deficit is creating a powerful tailwind for developers with advanced projects. Green Bridge Metals is moving decisively to capitalize on this environment, formally targeting the completion of a Preliminary Economic Assessment (PEA) for its flagship Serpentine project within the next 18 months. This strategic timeline coincides with copper prices on the London Metal Exchange hitting $12,138 per tonne in early April, supported by analyst forecasts of a global supply shortfall exceeding 100,000 tonnes for 2026.

At the heart of this push is the Serpentine copper-nickel project in Minnesota's Duluth Complex. The company currently has six new drill sites undergoing the permitting process with the Minnesota Department of Natural Resources. Phase one of a diamond drilling campaign is scheduled for the second half of 2026, comprising six to ten holes over 2,000 to 2,500 meters. Contractor Foraco, already working on Green Bridge's other projects, is slated to execute the program.

A key differentiator for this upcoming campaign is its expanded analytical scope. For the first time, a full multi-element analysis will be conducted to systematically assay for platinum group metals (PGMs) and cobalt. These elements are not currently included in the project's existing resource model, meaning their evaluation could positively impact the overall copper-equivalent grade. The program also includes plans for geophysical borehole surveys to refine structural interpretations and guide future drilling.

Serpentine already rests on a substantial defined mineral resource: 21.6 million tonnes of indicated resources grading 0.46% copper, plus 279.9 million tonnes of inferred resources at 0.37% copper. The forthcoming drilling aims to both confirm and expand this base, with all new data feeding directly into the PEA study.

Investor attention is also focused on the company's Titac South prospect, where assay results are pending. Drilling that began in late January 2026 has completed three diamond drill holes totaling 1,196 meters. Geological logging has visually identified sulfide mineralizations, including chalcopyrit as disseminations and veins, across intervals ranging from approximately 100 to 450 meters in all three holes. The company will communicate specific grades only after receiving and verifying certified laboratory data.

The regional investment climate in Minnesota provides additional momentum. Mesabi Metallics recently secured a $520 million credit facility to support the operation of a $2.5 billion iron ore mine in northern Minnesota, marking the state's first new taconite mining operation in nearly fifty years. This significant capital commitment underscores the area's mining potential.

Green Bridge Metals' share price has advanced approximately 120% since the start of the year, though it currently trades about 35% below its 52-week high. The stock is hovering just below its 50-day moving average. The pending Titac South assay results and the finalization of Serpentine drill permits, both expected before year-end, represent immediate catalysts that will directly influence the path to the targeted PEA.
