Helius Minerals Executes Amending Agreement for the Serra Pelada Gold-PGM Project

Helius Minerals Limited has executed an amending agreement with Colossus Minerals Inc. to modify certain terms of their existing Exclusivity, Share Option and Acquisition Agreement for the Serra Pelada Gold-PGM Project. The original definitive agreement was signed on March 3, 2025, and the amending agreement was executed on October 22, 2025.

The Serra Pelada project represents a significant gold and platinum group metals opportunity, though the specific details of the amendments to the acquisition terms were not disclosed in this announcement. Such amending agreements typically involve modifications to transaction timelines, consideration structures, or due diligence requirements as parties work toward completing complex mineral asset acquisitions.

For the mining sector, this type of corporate development reflects the ongoing consolidation activities in the gold and PGM space, where companies are adjusting deal structures to optimize transaction outcomes. The fact that both parties are proceeding with amendments rather than terminating the agreement suggests continued commitment to the transaction, though investors will likely seek additional details about the specific modifications and their implications for the deal timeline and terms.
