This achievement would not have been possible without our team’s hard work at Fruta del Norte that resulted in improving recoveries and completing the plant expansion on time and on budget to increase the average plant throughput from 3,500 tpd to 4,200 tpd. 2021 was a successful year for Lundin Gold, and I look forward to another strong year in 2022.”
