Sierra Metals Inc. (TSX: SMT) (BVL: SMT) (“Sierra Metals” or “the Company”) is pleased to announce the discovery of a new high grade ore sulfide zone referred to as the “Fortuna” zone, located adjacent to the current mine operations. The discovery comes as part of an ongoing exploration drilling program at the Yauricocha Mine.
To date, 8 holes have been executed from the 720 level of the Yauricocha Mine within the Yauricocha System. These holes have intercepted mineralization containing high-grade Copper, Zinc and Lead zones. These results demonstrate the potential for high grade mineralization within the reported, and surrounding, areas.
Luis Marchese, CEO of Sierra Metals stated: “Today’s results represent significant progress in our efforts to expand Yauricocha’s ore resource within currently permitted levels of the mine. Mining of this readily accessible new high grade zone will increase expected ore grade for the next couple of years. We are working towards accessing part of the orebody as early as Q3 of 2022 which would have a positive impact on head grades in the second half of 2022.”
Alonso Lujan, Vice President, Exploration of Sierra Metals commented: “The reported results from the Fortuna zone, located laterally, between the Esperanza zone and Cachi Cachi Mine demonstrates the continued resource potential within the Yauricocha Mine.” He added, “The high value ore that has been defined suggests that continued exploration in the area is warranted, to better define its potential.”

Method of Analysis
Samples are prepared at the Yauricocha lab facilities at the Chumpe Mill, which is located on site. Drill core samples from the mine are assayed utilizing two procedures. Silver, Lead, Zinc and Copper are assayed by atomic absorption. Gold is fire-assayed with an atomic absorption finish. Diamond drill core samples sent for analysis consist of half NQ size or BQ size drill core which is split on site.
Quality Control
Américo Zuzunaga, FAusIMM CP (Mining Engineer) and Vice President of Corporate Planning, is a Qualified Person under National Instrument 43-101 – Standards of Disclosure for Mineral Projects.
