TORONTO, Sept. 5, 2017 /PRNewswire/ - Sierra Metals Inc. (TSX: SMT) (BVL: SMT) (NYSE AMERICAN: SMTS) ("Sierra Metals" or "the Company") today announced assay results from a recently completed definition drilling program at the Bolivar West zone which is located adjacent to the current operations at the Bolivar Mine. The highlight of this program is that at completion the drill information will be included in a future resource update for the Bolivar Mine located in Urique, Chihuahua state, Mexico.

Our exploration programs have identified skarn ore deposits in the form of mantos in the area extending for eight kilometers.  The brownfield drilling program completed had been designed with a target of increasing the grades being mined at the Bolivar Mine and defining further mineral resources.  Drilling results have been summarized in Table 1 below.

Alonso Lujan, Vice President Exploration at Sierra Metals stated: "The assay results have positively confirmed the existence of higher grade copper mineralization with an average copper equivalent grade of 2.55%.  This will help to increase head grades at the mill when this material is included in the future mine plans. The assay results have also provided the necessary data needed to update our current resource base for the Bolivar mine. The update is planned for completion in Q4 2017." He continued, "We believe the Bolivar mining district has an attractive potential for further exploration success."

"This is an important advance for the uncovering of the asset value of our Bolivar Copper Mine." stated Igor Gonzales, President and CEO of Sierra Metals. "Today's results confirm the existence of higher copper grades and an additional deposit which may support potential future throughput expansions. We are excited by the potential shown by these results, and how it will help to positively transform current operations and future cashflows at Bolivar." He continued, "Finding higher grade areas at Bolivar has been a strategic focus for our exploration team in order to increase cashflows generated from our operations. Historically, Bolivar has mined high grade copper/zinc/silver zones and we think the current exploration programs have the potential to identify additional resources with similar grades as the current drilling results demonstrate."

He concluded, "Brownfield exploration has played a very important role to drive a potential expansion of mineral resources at all three Sierra Metals mines. The drill results announced in our recent press releases for all the mines have demonstrated this.  We expect that their upcoming technical reports should confirm the potential for future expansions.  The continued brownfield drilling of high-value targets at all mines into 2018 is likely to continue producing potential mineral resource growth to support the company's growth plan in the medium term."

Bolivar Mine Geology

The Bolivar mine district encompasses 15,217 hectares over range of elevation of 1,950 to 700 meters above sea level in the Sierra Madre Occidental Mountain Range. It is the result of one of largest volcanic events in the world that occurred between the Cretaceous and the Tertiary periods. The Sierra Madre Occidental is formed by two volcanic groups. Upper Volcanic Complex and Lower Volcanic Complex. Within the sedimentary-vulcan sequence of the upper cretaceous in the Lower Volcanic Group the replacement deposits are developed in form of mantles.

The Sierra Madre Occidental is one of the largest known epithermal precious metal metallogenic provinces and is host to well-known gold and silver producing mining districts, including: Concheño, Ocampo, Bacis, Tayoltita, Topia, Guanacevi, La Cienega, Mulatos El Sauzal and Pinos Altos.

The mineralization at Bolivar West zone is located approximately 450 meters below the surface, and can occasionally be observed alterations at surface.
