Anteros Metals Confirms Hydrogen Up to 6,500 ppm During Ongoing Deep Drilling at Seagull Project
Anteros Metals has reported additional hydrogen-bearing gas results from its ongoing Phase 2 deep drilling program at the Seagull Property in northwestern Ontario, where the company continues testing a large geophysical target known as “Big Blue.”
According to the company, laboratory analyses confirmed the presence of hydrogen in all gas samples collected to date, with concentrations ranging up to 6,500 ppm (0.65% hydrogen). The highest hydrogen value was recorded from drill hole WM00-05EXT, located roughly 150 metres southwest of the primary Phase 2 hole. The same sample also contained nitrogen, carbon dioxide, and methane.
A separate gas occurrence encountered in drill hole WM08-27EXT at approximately 825 metres depth returned a gas composition dominated by carbon dioxide, along with smaller amounts of nitrogen and up to 400 ppm hydrogen. Importantly, methane was absent from those samples. Geological review identified multiple fractures and joints associated with the gas-bearing interval, supporting the company’s interpretation that gas migration is structurally controlled within basement rocks beneath the Seagull Intrusion.
Anteros stated that repeat gas occurrences observed across multiple drill holes continue to support the concept of an active basement-hosted fluid system associated with the Midcontinent Rift geological setting. Management noted similarities between the CO₂-rich gas signature at Seagull and other deep mantle-linked gas systems observed elsewhere within the Midcontinent Rift.
The company has now shifted drilling activities toward further testing of the deeper “Big Blue” target, which is interpreted as a potential source area for the upper gas-bearing zones identified during earlier drilling. Current drilling at hole WM00-05EXT has advanced to approximately 1,000 metres depth, while the deeper geophysical target is estimated near 1,400 metres.
Anteros emphasized that the gas analyses remain preliminary and that the company has not yet completed sufficient work to determine the source, continuity, reservoir characteristics, or commercial significance of the observed gas occurrences.
