Strategic Initiatives
Growth programs, investments, and their expected impact
A $280.0 million expansion project to transition the Marmato operation into a large-scale mechanized mine. The project involves accessing the porphyry-hosted Bulk Mining Zone below the epithermal Narrow Vein Zone and constructing a new 5,000 tpd Carbon-in-Pulp (CIP) processing plant.
Expected impact: Expected to significantly increase productivity and grow Marmato's annual gold production to approximately 200,000 ounces at steady state.
Expanding the processing capacity of the Maria Dama plant at the Segovia Operations from 2,000 tpd to 3,000 tpd. The expansion utilizes an existing unutilized ball mill on site and includes upgrading facilities that receive material from artisanal and small-scale contract mining partners.
Expected impact: Drives higher mill feed and supports Segovia's 2026 production guidance of 265,000 to 300,000 ounces.
Advancing the 100%-owned Soto Norte gold project in Colombia through a reframed, smaller-scale development plan. The new design reduces processing capacity to 3,500 tpd (including 750 tpd dedicated to local community miners) to optimize environmental stewardship and community integration.
Expected impact: Supports a designed mine life of 22+ years with an annual production of over 200,000 ounces of gold.
A strategic alliance with GreenYellow Colombia to construct and operate a 2 MWp solar plant to power the Segovia Operations.
Expected impact: Covers approximately 12% of Segovia's annual energy needs (generating 3.4 GWh per year) and reduces CO2 emissions by 516 tons annually.
