Toronto, ON – October 5, 2016Sierra Metals Inc. (TSX: SMT) (BVL: SMT) (“Sierra Metals” or “the Company” -,1323,Interviews/?v=295965) is very pleased to announce that the Yauricocha Mine achieved historic production for a second sequential month in September, 2016.  The Mine produced 83,661 Dry Metric Tonnes (“DMT”) or 2,789 tonnes per day on average for the month.  This is the most tonnage ever produced in one calendar month in the history of the Mine and exceeded the previous best month achieved in August 2016 of 82,149 DMT. 

Plant production at the Chumpe Mill at the Yauricocha Mine also set a historic record for a second sequential month with September, 2016 production totalling 82,043 DMT which includes polymetallic and oxides from third party sources. September’s record plant production exceeds the previous best month of August 2016 when 79,554 DMT were produced.

“I am very pleased to see record production for a second subsequent month at both the Yauricocha Mine and the Chumpe Mill” commented Mark Brennan, President and CEO of Sierra Metals. “These significant achievements continue to highlight the terrific job that our operations team have achieved implementing the modernization and operational improvement programs at the Mine.” He continued, “The team has positioned the Mine to drive higher value per tonne of ore mined as well as provide a path to higher production volume.  As mentioned previously, we expect to see some volatility in both parameters while work is completed on certain aspects of the improvement program like the commissioning of the new hoist at Mascota in November, however the foundation has again moved higher as we continue to see the benefits of our efforts.”

Spin-out of Peru Northern Properties

After completing a review and evaluation of its assets in Peru, Sierra Metals is anticipating spinning-out of the exploration stage properties of Piura, La Libertad and Cajamarca located in northern Peru to existing shareholders.  These properties represent approximately 37,000 hectares containing 57 concessions.  The spin-out would reduce the concession maintenance liability for the Company and allow for the properties accelerated exploration and development while enhancing value to Sierra shareholders.
