Igor Gonzales, President, and CEO of Sierra Metals stated: I am very pleased with the Companys performance during Q4 and full year 2018. Despite challenges such as harsh weather events in Q3 at the Bolivar Mine, the Company generated positive cash flow at its three operating Mines, realizing a 13% increase over 2017, and our production results were solid with year over year increases to the consolidated production of all metals except lead. The Company continues to realize positive returns on the capital investments and operational improvement efforts at all our Mines.This is best demonstrated through our improving operating performance, strengthening of our asset base, significantly lower all-in sustaining costs and continued strong cash flow.
