The model projected a weighted average grade of 0.69 Au g/t for the quarter; whereas, ore mined assayed 1.37 Au g/t. Due to this positive grade reconciliation and unusually heavy rains during the period, which slowed leach pad expansion, mining efforts were directed to waste removal. Ore tonnes mined were approximately 871,000 tonnes less than plan and waste removal exceeded plan by 694,000 tonnes. The current leach pad expansion program was completed in April and there is sufficient capacity for the next quarter.
