Stock Information

Our Feasibility Study, completed in March 2015, was not just about numbers but about balancing commercial viability with environmental sustainability and social responsibility. Here are some key data points:

  • Average annual gold production: 205,000 oz 

  • Proven & Probable Mineral Reserves: 3.8 million oz 

  • Post-Tax IRR: 26% ($1,200/oz Au)

  • Post-Tax NPV: $665 million (5% discount rate) 

Estimated Project Construction Schedule

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 with a delivered head grade of 1.30 g/t. 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.
