IsoEnergy Ltd. filed a Form SD stating that Conflict Minerals are not applicable.

Queen's Road Capital Investment Ltd. filed a Schedule 13G disclosing it owns 2,740,434 IsoEnergy Ltd. common shares, equal to 5.003 % of the outstanding class. The Cayman-incorporated investment firm holds sole voting and dispositive power over the entire position.
The ownership threshold was crossed on 05 May 2025 and the filing was signed on 07 Aug 2025 by President Alex Granger.
