Timeline

Mining

The Project's Feasibility Study outlines plans for open pit mining using a fully owner-operated equipment fleet. Initially, the mine is designed to produce 3.5 million tonnes per year, escalating to a full production of 7 million tonnes per year by the third year. Material from the pre-production stripping’s last three months will commission the process plant.

Over the mine's lifetime, an average strip ratio of 4.3:1 is anticipated, with open pit bench heights of 10 meters. Ore will be hauled using 136-tonne haul trucks and corresponding loading equipment, maintaining a stockpile adjacent to the primary crushing plant to mitigate potential weather-related mining interruptions. Concurrently, waste rock will be transported to designated waste management facilities near the open pits, ensuring streamlined and environmentally conscious operations.

Metallurgy

Extensive feasibility-level test work completed by SGS using representative run-of-mine composites confirmed that the Volta Grande Project mineral deposits are suitable for a conventional crush, grind, gravity concentration, leach, and carbon-in-pulp (CIP) flow sheet.

These tests indicate that 40% to 50% of the gold will be recovered in a gravity concentrate, contributing to an overall estimated gold recovery of 93% from all ore types processed during the mine's lifespan. This efficient recovery rate optimizes the Project’s resources while safeguarding the surrounding environment.
