Mark Brennan, President and CEO of Sierra Metals stated We have been seen tremendous growth in ore throughput and copper production at the Bolivar Mine over the past 5 years, however we have also seen ore grade erosion that has partly offset the expansion benefits of our earnings potential. Since 2015 we have been working aggressively to add new higher-grade, higher-value tonnage at Bolivar. Our objectives for 2017 are to increase production further, reduce costs and complete successful brownfield exploration that can be brought into the production schedule in 2018. He continued, The Bolivar district is prolific in its geological activity. We are optimistic that we can add resource tonnage while also improving ore grade. This makes us optimistic for our cash flows and EBITDA outlook in 2018.
