Green Bridge Metals Nears Inflection Point as Serpentine Permit Decision Aligns with Titac South Assays

Junior explorer Green Bridge Metals awaits Minnesota regulatory ruling for Serpentine copper-nickel project while final assays from Titac South reveal broad polymetallic intercepts, with stock up 90% YTD.

For Green Bridge Metals, the coming weeks represent a convergence of two critical developments that could reshape the company’s near-term trajectory. In Minnesota, the junior explorer is waiting on a regulatory ruling that would unlock its flagship Serpentine copper-nickel project, while simultaneously fielding final assay results from the Titac South drilling campaign that has already broadened the project’s polymetallic profile.

The stock closed at €0.12 on Friday, advancing 4.29% on the day but posting a weekly loss of 2.41%. Since the start of the year, the shares have gained roughly 90%, though the price remains nearly 47% below the February peak.

Serpentine: The Bigger Prize

Serpentine sits 5.5 kilometres southeast of Babbitt in St. Louis County, within the Duluth Complex and adjacent to the NorthMet and Sunrise deposits. The project already hosts an indicated resource of 21.6 million tonnes grading 0.46% copper, plus an inferred resource of 279.9 million tonnes at 0.37% copper and 0.12% nickel.

Minnesota’s environmental agency has been reviewing a formal exploration plan since late April, and a decision could come as early as June. If approved, Green Bridge plans to drill six to ten holes totalling up to 2,500 metres, with a window from June 2026 through June 2027. The drill contractor Foraco is already under contract. Beyond confirming the existing resource estimate, the programme will test for cobalt and platinum-group elements — metals absent from the current resource calculation. Management intends to deliver a preliminary economic assessment within 18 months of the start of drilling.

The regulatory backdrop has also shifted. President Trump permanently lifted a mining moratorium covering more than 225,000 acres in the Superior National Forest, a 20-year ban that had cast a long shadow over Duluth Complex developers. That change improves the political climate for projects such as Serpentine, but it does not substitute for the permit itself.

Titac South Delivers Polymetallic Widths

While Serpentine awaits its green light, the Titac South programme has already produced significant intercepts from the first batch of assays. All six holes of the Phase 1 campaign encountered sulphide mineralisation, validating the company’s geological model.

Hole TS26-005 cut 152 metres at 0.31% copper, along with 13.7% titanium dioxide and 0.15% vanadium oxide. TS26-003 returned 190 metres at 0.30% copper, including a 14-metre section grading 0.48% copper, with 0.13% vanadium oxide. These results confirm that Titac South is not merely a titanium story — the polymetallic nature is coming into sharper focus.

Three drill holes remain unassayed, including a critical step-out testing a previously unchecked geophysical anomaly. That hole could determine whether the known mineralisation extends laterally. A newly completed 3D inversion of VTEM airborne data has identified four to five additional untested anomalies with conductive and magnetic signatures similar to the known mineralised intrusions, providing a pipeline of future targets.

An independent laboratory is currently assaying the pending samples for platinum-group metals and cobalt, elements that were not part of the earlier resource work.

Market Tailwinds and a Regulatory Setback

Broader market dynamics are also working in Green Bridge’s favour. US copper imports doubled in the first quarter to 533,000 tonnes, and analysts expect tariffs on foreign copper to be announced soon, sharpening interest in domestic supply projects. That macro backdrop lends weight to both Serpentine and Titac South.

On the regulatory front, the company has cleaned up a compliance issue from late April. The British Columbia Securities Commission ordered Green Bridge to remove a website — maintained by an external PR firm — that contained unauthorised economic projections for Serpentine. The company took down the page, terminated the PR programme, and has since tightened its disclosure controls. The stock lost more than 6% on the day of the announcement.

To bolster its operational capacity, Green Bridge added three experienced professionals in May: Justin Brown as senior geologist and operations manager, Jay Robbie as senior geologist and technical advisor, and Sam Shahrokhi as vice president of corporate development. Brown brings seven years of Duluth Complex experience, a direct fit for the company’s Minnesota projects.

The stock remains above its 200-day moving average of €0.10, reflecting the long-run upward trend, but the gap between the current price and the February high highlights the uncertainty that still pervades the stock.

What Comes Next

The next few weeks will deliver hard data on both fronts. The final Titac South assays will either reinforce the exploratory model or introduce new questions, and the Serpentine permit decision will set the timeline for the company’s most consequential project. Together, these two catalysts will define whether Green Bridge can convert its 90% year-to-date gain into a sustained re-rating.
