Helius Minerals Limited has executed an amending agreement with Colossus Minerals Inc. to modify key terms of its previously announced plan to acquire a 75% beneficial interest in the Serra Pelada Gold-PGM Project in Brazil. The updated agreement provides Helius with greater flexibility to secure necessary regulatory and stakeholder approvals before closing the acquisition. The amendment also allows for an extension of the option period by 30 business days, with the possibility of further extensions by mutual consent, and defers the issuance of special warrants to Colossus until closing. Additional closing conditions have been introduced, including approvals related to a debt plan and a rehabilitation plan, to support the structured advancement of the acquisition and the restart of the Serra Pelada Project.
