An early-stage exploration project in northwestern Ontario targeting natural hydrogen, helium, and platinum group element mineralization within a large mafic–ultramafic intrusive complex associated with the Midcontinent Rift, focused on the deep Big Blue geophysical anomaly and structurally controlled gas occurrences.

Natural hydrogen exploration at the Seagull Property involves deep drilling into a mafic–ultramafic intrusive complex and Archean basement rocks to intersect gas-bearing fractures and collect pressurized gas samples for laboratory analysis.[1][6][7] The objective is to identify and characterize naturally occurring hydrogen, helium, and associated gases within structural and lithological traps linked to the Midcontinent Rift system.[1][7]

The Seagull gas samples are analyzed at AGAT Laboratories using standard hydrocarbon and non-hydrocarbon gas analysis methods, including GPA 2261, GPA 2286, GPA 2145, AGA #5 and TP‑17, to quantify concentrations of hydrogen, carbon dioxide, nitrogen, methane, and hydrogen sulphide.[1][2] These methods provide reliable compositional data needed to assess the presence and relative abundance of natural hydrogen within mixed gas streams.[1][2]

The Big Blue target at the Seagull Property is a large deep-seated low acoustic velocity geophysical anomaly interpreted from seismic and other geophysical data as a structurally altered or fractured zone, potentially related to mafic–ultramafic intrusion and associated gas-bearing structures.[6][9] It serves as the primary subsurface target guiding the placement and depth of Phase 2 drill holes designed to intersect potential natural hydrogen, helium, and magmatic sulphide mineralization.[6][7]
