Production began at Rodeo in January 2021, with a second ball mill installed and operating at the end of April which enabled the Company to easily exceed its targeted processing rate of 450 tonnes per day (“tpd”). As production ramped up in the second quarter, the Company saw a temporary drop in gold recovery from 84% in Q1 to 78% in Q2 related primarily to higher than planned throughput, which in turn yielded slightly coarser grind and lower gold recovery. The Company believes it will be able to improve gold recovery as it targets 550 tpd throughput and optimizes the operation of the leach and extraction circuits at the plant during the third quarter. Target recovery for gold as indicated in metallurgical test results is 85%.
