Sierra Metals Announces Memorandum of Understanding with Jinchuan Group Co., Ltd, in Mexico

TORONTO, Sept. 28, 2017 /CNW/ - Sierra Metals Inc. (TSX: SMT) (BVL: SMT) (NYSE AMERICAN: SMTS) ("Sierra Metals" or "the Company") is pleased to announce the signing of a Memorandum of Understanding ("MOU") with Jinchuan Group Co Ltd ("Jinchuan"). The MOU, executed September 26, 2017, formalizes the intentions of the parties in respect of their cooperation focused on the Jinchuan's Bahuerachi copper mining project's development in Chihuahua, Mexico.

Jinchuan acquired the Bahuerachi copper porphyry deposit in connection with its acquisition of Tyler Resources Inc. in 2008 and has conducted multiple geologic and engineering studies with an aim to developing a large scale open pit copper mine. The Bahuerachi project concessions are adjacent to Sierra Metals' Bolivar copper mine concessions.  The Bolivar mine started commercial production in 2012 and has successfully expanded its copper production levels over the past five years and more recently conducted a more aggressive exploration program with the objective to increase its resource tonnage and copper ore grades.

The MOU has the objective of accelerating the cooperation between Jinchuan and Sierra Metals at the Bahuerachi mining concessions in a manner that is value enhancing and mutually beneficial to both companies and capitalizes on Sierra Metals' success in operating in Latin America and particularly in the Bahuerachi region.  The MOU is a non-binding agreement that both parties will negotiate in good faith to evolve into a specific comprehensive cooperation agreement to govern their relationship.

J. Alberto Arias, Chairman of the board of Sierra Metals, stated "we are delighted to have progressed discussions with Jinchuan to formalize of a memorandum of understanding and we are looking forward to accelerating the development of the Bahuerachi project in partnership with Jinchuan.  We expect to be able to take advantage of the synergies in our operations at Bolivar, sharing our expertise and local know-how.  We value our relationship with Jinchuan and foresee further growth opportunities for both companies working together in Mexico and Latin America."

Igor Gonzales, Sierra Metals' CEO, stated "our technical teams have already been discussing multiple development alternatives and we are excited to participate in them in a way that should allow further growth to our Mexican production levels in a disciplined capital way."

Mr. Chen Dexin, Director and President of the Jinchuan Group, said, "Jinchuan attaches great importance to cooperation with Sierra Metals and hopes the two companies will take the Bahuerachi project as an opportunity to explore extensive cooperation in more areas and give full play to each other's respective advantages, to combine strengths to achieve win-win outcome."
