Early Deposit Mineral Stream Interests
Early deposit mineral stream interests represent agreements relative to early stage development projects whereby Wheaton can choose not to proceed with the agreement once certain documentation has been received including, but not limited to, feasibility studies, environmental studies and impact assessment studies (please see Note 24 for more information). Once Wheaton has elected to proceed with the agreement, the carrying value of the stream will be transferred to Mineral Stream Interests.
The following table summarizes the early deposit mineral stream interests owned by the Company as of June 30, 2026 and December 31, 2025:
