Sierra Metals Reports Fourth Quarter and Year-End 2017 Financial Results
During 2017, silver equivalent production increased by 26%, copper equivalent production decreased 1%, and zinc equivalent production decreased by 9% compared to 2016. During Q4 2017, silver equivalent production increased by 15%, copper equivalent production decreased 12%, and zinc equivalent production decreased by 8% compared to Q4 2016. The decrease in metal production was due to lower production in Mexico, partially offset by record throughput, which led to an increase in production, in Peru. The temporary decrease in metal production in Q4 2017 compared to Q4 2016 was primarily due to lower throughput, head grades, and recoveries at the Bolivar Mine, and decreases in throughput and recoveries at the Cusi Mine.
