Regulatory Relief and Geophysical Advances Reshape Green Bridge Metals' Critical Minerals Prospects in Minnesota
03.06.2026 - 15:43:15 | boerse-global.de
The removal of a two-decade state-level mining moratorium in Minnesota has fundamentally altered the landscape for developers in the Duluth Complex, and Green Bridge Metals is one of the early beneficiaries. The company, long viewed chiefly as a titanium-focused explorer, is now revealing a much broader critical minerals story — one that combines copper, vanadium, and platinum-group elements with its established titanium dioxide inventory. This shift has been driven by a sophisticated 3D geophysical model that has already turned up fresh drill targets.
A 3D-VTEM inversion analysis at the Titac project has identified between four and five previously unknown anomalies. Crucially, these anomalies share the same geophysical signature as the known mineralised zones at Titac South and Titac North — coincident magnetic highs and conductive responses. The model refines preliminary VTEM data from May 2025 and is now being used as a primary tool for target generation. Management views the technique as an effective means to expand the exploration envelope quickly.
The assay results from the first three holes of the Phase-1 drilling programme have already confirmed the polymetallic nature of the system. Hole TS26-005 returned 152 metres at 0.31% copper, 13.7% titanium dioxide and 0.15% vanadium oxide. Hole TS26-003 was even longer: 190 metres at 0.30% copper and 0.13% vanadium oxide, including a 14-metre section grading 0.48% copper. All six holes drilled intersected sulphide mineralisation, according to CEO David Suda, but the assay results for the remaining three holes are still pending. Among those is a strategic step-out hole targeting a geophysical anomaly that has never been tested before. The outcome will determine whether the mineralised envelope extends laterally.

Alongside Titac, the company is advancing its flagship Serpentine copper-nickel project in St. Louis County, which borders the NorthMet and Sunrise deposits. Serpentine hosts an inferred resource of roughly 280 million tonnes at 0.37% copper and 0.12% nickel, plus an indicated resource of 21.6 million tonnes at 0.46% copper. A Phase-1 diamond drilling campaign of six to ten holes totalling between 2,000 and 2,500 metres is planned for the second half of 2026. Foraco has been contracted as the drilling company. The programme aims to verify the resource and test for cobalt and platinum-group elements. A preliminary economic assessment is expected within 18 months of drilling. The operation plan is currently under review by the Minnesota Department of Natural Resources.
The regulatory backdrop has brightened considerably. President Trump has permanently lifted the 20-year mining moratorium that covered more than 225,000 acres in the Superior National Forest. The new legislation cannot be reversed by future administrations, removing what had been the single largest regulatory obstacle for developers in the Duluth Complex.
The stock currently trades at around EUR 0.12, nearly 48% below its February high of EUR 0.23 and 44% off its 52-week peak of EUR 0.22. Despite the recent pullback, the shares have gained roughly 88% year to date, buoyed by the improving mining sentiment in Minnesota and the company’s strengthening geological story.
Investors now face two key catalysts in the coming weeks: the pending Titac assays and the DNR permit decision for Serpentine. Success on either front would validate the expanded exploration model and could reignite the momentum that carried the stock to its February highs.
