- Company files NI 43-101 Technical Report for Yauricocha Mine and is set to commission larger capacity hoist at the Mascota Shaft
- Company seeks permission from Shareholders for share consolidation as predecessor to potential U.S. listing
TORONTO, Sept 12, 2016 /CNW/ - Sierra Metals Inc. (TSX: SMT) (BVL: SMT) ("Sierra Metals" or "the Company") is very pleased to announce that the Yauricocha Mine achieved historic production in August, 2016. The Mine produced 82,149 Dry Metric Tonnes ("DMT"), or 2,733 tonnes per day on average for the month which is the most ever produced in one calendar month in the history of the Mine, exceeding the previous best month achieved in December 2014 of 80,900 DMT.
Plant production at the Chumpe Mill at the Yauricocha Mine also set a historic record for the month of August, 2016 with production totalling 79,554 DMT which exceeds the previous best month of October 2014 when 74,997 DMT were produced.
"These are remarkable achievements that would have been deemed highly unlikely just ten short months ago when we began our operational improvement program at the Mine" commented Mark Brennan, President and CEO of Sierra Metals. "The operations team led by our COO, Gord Babcock, began the modernization and operational improvements at the mine starting late in the third quarter of last year. They have done a great job in putting the Yauricocha Mine into position for driving both higher value per tonne of ore and production volume." He continued "That said there will be volatility in both parameters as we move forward and work to complete certain aspects of the improvement program, however the bar is steadily moving higher as we begin to see the benefits of our efforts."
New Hoist Installation at Mascota Shaft 720 Level, Yauricocha Mine
Starting on November 1, 2016 Sierra Metals plans to transition from the current operating surface hoist to a new Hepburn 104 x 45 double drum 1100 HP production hoist currently installed on the 720 level, where it will service the Mascota Shaft. This new hoist has an installed capacity of 106,000 metric tonnes ("MT") per month based on Hepburn performance data. The hoist is capable of servicing the mine from the 680 level to the 1400 level, which is the undeveloped lower part of the mine (approximately 715 metres deep).
The new hoist will be hoisting from the 680 level to below the 1070 level (last level accessible from Mascota shaft) so that the hoisting distance is reduced to approximately 365 metres. With the shorter hoist distance, we expect to achieve other benefits including reduced hoist time, improved duty cycle as well as less hoist rope in movement in the shaft. Overall, once final commissioning and implementation is complete, management expects that there may be more opportunity to benefit from increased hoisting capacity in excess of the 106,000 MT per month capacity due to the shorter skipping distance.
The new hoist is expected to increase the current hoisting capacity by approximately 30,000 MT per month, and will help as we continue with our goal of increasing production in the future at Yauricocha. The current CIR hoist has an installed capacity to skip 70,000 MT per month from the mine.
As part of the installation and transition from surface to the 720 level we anticipate that there will be a 25-day shutdown and a planned production shortfall for November of approximately 42,000 MT. The Company has started stockpiling material on surface to help mitigate the effects of the shutdown. Production levels are expected to return to normal starting in December.

- Proven and Probable Mineral Reserves of 1,520,000 tonnes averaging 51.8 g/t silver, 1.20% copper, 1.12% lead, 2.87% zinc and 0.43 g/t gold.
- Measured and Indicated Resources of 2,534,000 tonnes averaging 68.9 g/t silver, 1.71% copper, 1.26% lead, 3.23% zinc and 0.55 g/t gold.
- Inferred Mineral Resources of 1,541,800 tonnes averaging 69.0 g/t silver, 1.87% copper, 0.92% lead, 2.49% zinc and 0.63 g/t gold.
The Report also included Reserves and Resources for all of Yauricocha (including Esperanza) with:

- Inferred Mineral Resources of 3,745,000 tonnes averaging 49.1 g/t silver, 1.33% copper, 0.58% lead, 1.86% zinc and 0.53 g/t gold.
Notes on Reserve and Resource Estimate
The effective date of the mineral reserve and resource statement for the Yauricocha Mine including Mina Central, Cachi-Cachi, Mascota and Cuerpos mineral reserve and resource estimate is Dec 31, 2015. The effective date for Esperanza is June 30, 2016. Details of the estimate are provided in the Company's August 11, 2016 press release. A NI 43-101 compliant technical report to support the estimate has been filed on SEDAR on September 12, 2016. Measured and Indicated Resources include Proven and Probable Reserves.
Silver equivalent is based on the following metal prices: US$16.76/oz Ag, US$2.28/lb Cu, US$0.86/lb Pb and US$0.94 Zn and US$1,251/oz Au.
Mineral resources that are not mineral reserves do not have demonstrated economic viability.
For a specific breakdown of each category of resources (measured, indicated and inferred) and reserves (proven and probable), please refer to the Report.

Sierra seeking permission from shareholders for share consolidation as predecessor to potential U.S. listing
Sierra Metals is seeking permission from its shareholders to consolidate the issued and outstanding common shares ("Common Shares") of the Company (see the Company's management information circular dated as of August 27, 2016 (the "Circular") filed on Sedar on September 6, 2016). The Circular seeks an amendment to the Company's articles to consolidate the issued and outstanding Common Shares on the basis of one Common Share for every two Common Shares issued and outstanding, or such other consolidation ratio that the Board deems desirable to a maximum of one post-consolidation Common Share for every five pre-consolidation Common Shares.
Sierra Metals has been considering whether a listing on a US stock exchange could benefit the Company. However, to qualify for listing the price of the Common Shares must meet a minimum threshold. As such, the Company would first need to complete a consolidation designed to increase the price of the Common Shares. A final decision to proceed with a listing on a U.S. exchange has not been made and the Company may elect not to proceed with a listing even if the consolidation is approved by the shareholders.
All technical data contained in this news release has been reviewed and approved by Gordon Babcock, P.Eng., Chief Operating Officer and a Qualified Person under National Instrument 43-101 – Standards of Disclosure for Mineral Projects.
