Sierra Metals Receives Permits for Additional Surface Exploration Drilling and Tailing Dam Expansion at Its Yauricocha Mine

Sierra Metals Inc. (TSX: SMT) (BVL: SMT) (NYSE AMERICAN: SMTS) (“Sierra Metals Inc.” or “the Company”) is pleased to report that the Company has received its permit to construct the expansion of the tailing dam facility as well as its permit for the surface drilling program at its Yauricocha Mine in Peru.

Igor Gonzales, President, and CEO of Sierra Metals Inc. commented. “This is exciting news for the Company. Receipt of the construction permit for the tailings dam follows the previously obtained EIA permit. Construction has already begun on the completion of the next lift at the tailing’s facility and is an important step in the process for a future throughput expansion at the Yauricocha Mine. Additionally, surface drilling of four high-value drill targets which were identified as part of a recent Titan 24 geophysical survey and through surface sampling has also begun. We are excited to see the drills turning and look forward to the results and the potential discovery of new mineralized zones.”

He continued “Over the past 18 months, Yauricocha has been successfully drilling near-mine targets identified by Titan 24 from underground drill stations, which was successful, but has many space constraints and limitations. The surface drilling required a long permitting process, but now that has been obtained, will allow us to test previously untested top priority areas from the Titan 24 survey. Our experience with Titan 24 has been extremely positive at our Bolivar copper mine in Mexico identifying important new mineralized areas and we look forward to have the same strategy in Peru.”

Construction at the tailing dam is permitted and will take place in two stages. In the first stage the Company is permitted to complete a two meter lift. Once complete the Company will amplify the area of deposition for the next stage, which will include an additional lift of two more meters. In total, once completed the Company will have finalize a four meter lift that will add approximately three years of capacity, assuming a throughput rate of 3,000 tonnes per day.

All drilling targets have been prioritized by previous geochemistry sampling as well as geophysical work and they are all significant, high priority targets for testing. Areas to be tested as part of a surface drilling program include:

The Doña Leona area located 2.5 kilometers southeast from the Central Yauricocha Mine. This area has already had surface geochemical sampling completed on structures and gaps, which provided values ??in anomalous silver, zinc, lead, and copper. Furthermore, geophysics from a Titan 24 survey shows significant anomalies in this area. Eight drill holes totaling 8,000 meters will be drilled from five platforms to test these targets for high grade structures.

The El Paso – Éxito areas are located between 3.5 and 5 kilometers southeast of the Central Yauricocha mine. The Éxito mine contains skarn and replacement mineralization and surface sampling detected structures with high values ??of anomalous lead, zinc, and copper. Geophysics with the Titan 24 geophysical survey have determined important anomalies in the area. Ten drills holes totaling 10,170 meters will be completed from six platforms to test these targets for high grade structures.

The Kilcaska area located 7.5 kilometers southeast of the Central Yauricocha mine is the third target to be tested. This previously exploited area along with surface sampling have produced strong values of anomalous silver, lead, zinc, and copper. Kilcaska has not had any geophysical work completed. Four holes totaling 2,120 meters will be executed from two platforms to test these targets for high grade structures.

The Victoria area located 1.5 kilometers southeast of the Central Yauricocha mine is the fourth target to be tested. The Victoria area has a high geological potential since it has previously had narrow veins exploited with values ??in anomalous copper, lead, zinc. Likewise, on the surface of this zone, there is a series of quartz veins and veinlets, with anomalous copper, lead and zinc in stockwork type zones. Additionally, outcrops of marble and skarns also contain veins with values ??of anomalous copper, lead, zinc, and silver. In this area, geophysics from the Titan 24 geophysical survey identified important anomalies in the contact area and the granodiorites. Ten drill holes totaling 9,300 meters will be drilled from five platforms to test these targets for high grade structures.

Statements concerning mineral reserve and resource estimates may also be considered to constitute forward-looking statements to the extent that they involve estimates of the mineralization that will be encountered if and when the properties are developed or further developed. These statements relate to analyses and other information that are based on forecasts of future results, estimates of amounts not yet determinable and assumptions of management. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as “expects”, “anticipates”, “plans”, “projects”, “estimates”, “assumes”, “intends”, “strategy”, “goals”, “objectives”, “potential” or variations thereof, or stating that certain actions, events or results “may”, “could”, “would”, “might” or “will” be taken, occur or be achieved, or the negative of any of these terms and similar expressions) are not statements of historical fact and may be forward-looking information.
