Royalty Liability	8.Royalty Liability The NORI Royalty (including Areas A to D) (Note 7) was recorded as a royalty liability in the consolidated Balance Sheet in accordance with ASC 470, Debt. The Company elected to account for the royalty liability at fair value through profit and loss. The fair value of Areas A to C was determined using a market approach which entails examining recent royalty transactions prior to the reporting date, focusing on those transactions that involve similar metals as contained in NORI’s polymetallic nodules. As at June 30, 2026, the Company compared the specific characteristics of these transactions and estimated the fair value for Areas A to C at $15 million, unchanged from March 31, 2026. The fair value of Area D was determined using an income approach following the Company’s completion and release of its PFS with respect to NORI Area D filed in August 2025 resulting with a fair value for Area D of $130 million as at June 30, 2026, unchanged from March 31, 2026. The discounted cash flow fair value reflects updated operational and economic assumptions, including the use of forward metal prices and a real discount rate, related to the NORI Area D project used in support of the PFS.
