RE:RE:RE:RE:RE:RE:Q4 2021 production was 49,497 ounces gold Processing
Material above the crushed ore cut-off grades will be hauled from the open-pits to the primary crusher. Ore will be crushed at a nominal rate of 30,100 tpd. Following primary crushing, ore will be conveyed through a secondary and tertiary crushing circuit to a final crush size of P80 6.5 mm. Crushed ore will be conveyed to one of the two in-valley heap leach pads.
Ore will be stacked in 10m high lifts using a mobile conveying and stacking system then primary leached for 90 days. The pregnant solution, laden with gold once leaching is complete, will be pumped to an ADR plant where gold will be stripped from the solution and poured into dor bars. Life of mine recovery is estimated at 70.8%, including ROM ore.
Ore will be mined and primary crushed 365 days per year. Ore will be stacked on the heap leach pads 275 days per year. A primary crushed ore stockpile will be used during the coldest 90 days of the year and the stockpile will be reclaimed to the secondary crushing circuit and loaded onto the pads during the 275 day stacking period.
A total of 123 million tonnes of ore will be processed, including 108 million tonnes of crushed ore and 15 million tonnes of ROM ore. The primary heap leach pad will hold 77 million tonnes while the secondary heap leach pad will hold 46 million tonnes. The secondary heap leach pad has potential excess capacity of approximately 50 million tonnes should it be required for mine expansion.
