Arrow Exploration Corp (TSX-V:AXL, AIM:AXL, OTC:CSTPF) told investors that proved reserves more than doubled at its mid-year review as the Icaco discovery in Colombia and its newly acquired Thorsby assets in Canada added sharply to the group's resource base. Proved, or 1P, reserves rose 110% from December 2025 to 11.4 million barrels of oil equivalent, while proved plus probable, or 2P, reserves increased 82% to 21.4 MMboe.
