Green Bridge Metals' Titac South Assays Confirm Polymetallic System as Geophysical Survey Lays Out New Targets

Polymetallic assays confirm copper, titanium, vanadium, and PGEs at Titac South; geophysics identifies additional targets; Serpentine project advances.

Green Bridge Metals has crossed a critical threshold at its Titac project in Minnesota, moving from years of visual core observations to laboratory-confirmed numbers. The first assay results from the Phase-1 diamond drilling program reveal a mineralised system that extends well beyond copper, incorporating titanium, vanadium and platinum-group elements.

Three of the six completed holes have now returned analytical data. Hole TS26-005 intersected 152 metres grading 0.31% copper, 13.7% titanium dioxide and 0.15% vanadium pentoxide. TS26-003 cut 190 metres with 0.30% copper, 11.4% titanium dioxide and 0.13% vanadium pentoxide. The three reported holes — TS26-002a, TS26-003 and TS26-005 — reached depths of 309, 410 and 477 metres respectively, yielding roughly 1,200 metres of core. Sulphide minerals such as chalcopyrite occur as disseminations and veinlets over intervals ranging from approximately 100 to 450 metres.

Chief executive David Suda noted that sulphide mineralisation was observed in every one of the six holes drilled to date. The polymetallic signature elevates Titac South beyond a pure copper play, with platinum-group metals adding a further dimension. Assays for the remaining three holes are still pending, including a step-out hole designed to test a geophysical anomaly that had never been drilled before.

That anomaly emerged from a full 3D inversion of the airborne VTEM geophysical data, which the company completed in parallel with the drilling campaign. The refined modelling has identified four to five additional, previously unknown targets that display coincident conductive and magnetic signatures — the same pattern seen in the known mineralised oxide ultramafic intrusions at Titac South and Titac North. The existing drill results already validate the exploration model, with geophysical picks lining up spatially with actual sulphide intervals.

Titac South sits within a project that already hosts an inferred mineral resource of 46.6 million tonnes grading 15% titanium dioxide, a figure established before this year's drilling. The latest data will feed into resource updates as more assays come in.

Meanwhile, the company's second Minnesota asset, the Serpentine project, is advancing through the permitting queue at the state's Department of Natural Resources. Serpentine carries 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 drilling programme of six to ten holes (2,000 to 2,500 metres) is planned, with a preliminary economic assessment pencilled in for within 18 months of permit approval.

Green Bridge bolstered its technical bench in early May, adding Justin Brown as senior geologist — he brings seven years of Duluth Complex experience — alongside Jay Robbie as technical adviser and Sam Shahrokhi as vice president of corporate development.

At the market, the stock has climbed nearly 97% year-to-date to €0.13, though it remains roughly 42% below its February peak of €0.22. The next catalysts are the outstanding Titac South assays — particularly the step-out hole into untested ground — and the outcome of the Serpentine permitting process, both of which could provide further concrete data points in the coming weeks.
