Sierra Metals reports November production of 75,452 tonnes at its Yauricocha Mine in Peru

• November production exceeds expectation during planned shut down for the installation of larger capacity hoist

TORONTO, Dec. 5, 2016 /PRNewswire/ - Sierra Metals Inc. (TSX: SMT) (BVL: SMT) ("Sierra Metals" or "the Company") is very pleased to report the production of 75,452 tonnes from the Chumpe Mill located at the Yauricocha Mine in Peru in spite of the Company's planned shut down for the installation of a larger capacity hoist at the Mascota shaft.

"We are very pleased with the production achievement at Yauricocha when compared to the expectations for the month" stated Mark Brennan, President and CEO of Sierra Metals.  "This again speaks to the proficiency and dedication of our excellent team at site who strive to achieve and beat expectations as shown not only with November's production achievement, but with the very successful operational improvements program and with production records achieved in August, September and October at the Yauricocha Mine."

Progress on the transition to the new, larger capacity hoist on the 720 level has gone very well.  The new hoist transition is expected to be completed and in operation by the end of the week and will not impact December's production schedule.  Benefits of the new hoist include cost savings, shorter hoisting distance, reduced hoisting time, improved duty cycles and less hoist rope in movement in the shaft.
