Marmato is a 100%-owned underground gold-silver operation in Caldas, Colombia. Its existing 1,000 tpd flotation plant is processing mill feed sourced primarily from development and stopes in the Bulk Mining Zone while Aris Mining constructs a new 5,000 tpd CIP plant. The 2022 PFS evaluated the Upper and Lower mines as an integrated operation, with 31.3 Mt of reserves scheduled over 20 years and base-case after-tax NPV5% of US$341.4 million. Construction remains scheduled for first gold from the new CIP plant in Q4 2026, followed by ramp-up through 2027 toward approximately 200 koz of annual gold production. Wheaton holds gold and silver streaming interests over the mine but does not own the operation.
