Green Bridge Metals Puts Hard Numbers on Critical Minerals Play as VTEM Model Unlocks New Drill Prospects

First three holes at Titac South confirm copper, titanium, vanadium, PGEs. VTEM model identifies up to 5 new targets; step-out hole assays pending.

The wait for laboratory confirmation is over at Green Bridge Metals' Titac South project in Minnesota, where the first three of six diamond drill holes have returned assays confirming a broad polymetallic system. But the real story may lie in what the company has yet to see: a step-out hole targeting an untested geophysical anomaly, and a fully inverted 3D VTEM model that has flagged up to five additional exploration targets.

Copper, titanium, vanadium and platinum-group elements all feature in the results from holes TS26-002a, TS26-003 and TS26-005, which together produced around 1,200 metres of core. The most eye-catching intervals came from TS26-005, which cut 152 metres grading 0.31% copper, 13.7% titanium dioxide and 0.15% vanadium pentoxide, and TS26-003, which returned 190 metres at 0.30% copper, 11.4% TiO? and 0.13% V?O?. Both intervals lie within the oxide ultramafic intrusions that host the project's known mineralisation. The company noted that these are down-hole core lengths; true thicknesses cannot yet be determined owing to the irregular geometry of the mineralised zones.

TS26-002a reached a depth of 309 metres and also encountered broad zones of copper sulphides, though the company did not release specific assay numbers for that hole in the initial batch. Chalcopyrite, the dominant copper mineral, occurs as disseminations and veinlets over intervals ranging from roughly 100 to 450 metres.

These early results build on an already defined inferred resource at Titac South of 46.6 million tonnes at 15% TiO?, based on a NI-43-101 compliant study. The new data add copper, vanadium and PGE components to a deposit originally valued for its titanium content.

A geophysical roadmap takes shape

Perhaps more consequential for the medium-term story is the completion of a full 3D inversion of the airborne VTEM geophysical data across the Titac property. The modelling has sharpened the resolution of conductive and magnetic signatures, identifying four to five previously untested anomalies that share characteristics with the known mineralised intrusions. Management views the strong correlation between geophysical targets and observed sulphide mineralisation as a validation that VTEM can serve as a primary targeting tool for future drilling—not merely a supporting dataset for the current campaign.

Three of the six Phase-1 holes are still awaiting assay results. One of those is a step-out designed to test a geophysical anomaly that has never before been drilled. Whether that intercept extends the known mineralised footprint or defines its boundary will be a key catalyst for the stock in the near term.

The political backdrop adds another layer. The U.S. Geological Survey's 2025 critical minerals list includes copper, titanium and vanadium—every one of the metals showing up in Green Bridge's drill core.

Serpentine waits in the wings

While Titac South commands attention, the company is also advancing the Serpentine project, also located in the Duluth Complex. An inferred resource of 280 million tonnes grading 0.37% copper and 0.12% nickel sits alongside an indicated resource of 21.6 million tonnes at 0.46% copper. The permitting process with the Minnesota Department of Natural Resources is underway, and a 6-to-10 hole drill program is planned. Management expects to deliver a preliminary economic assessment within the next 18 months.

The technical team received a boost in early May with the addition of three new hires, including senior geologist Justin Brown, who brings seven years of experience in the Duluth Complex.

The stock remains tethered to pending data

Green Bridge's shares last traded at €0.12, a level that leaves the company roughly 44–45% below the 52-week high of €0.22 set in February. The year-to-date gain of around 90% reflects the market's willingness to price in exploration optionality, but that premium could narrow if the pending assays fail to confirm continuity beyond the current drill pattern or if the step-out hole misses its target.

Two events will determine the next leg: the release of the remaining Titac South assays, and the outcome of the Serpentine DNR permitting process. Until then, Green Bridge Metals remains a well-positioned exploration name with a clear catalyst pipeline—but without the answer to the question of scale.
