(1) 2017 Silver equivalent ounces and copper equivalent pounds were calculated using the following metal prices: $19.50/oz Ag, $2.28/lb Cu, $0.85/lb Pb, $1.05/lb Zn, $1,369/oz Au. &nb

Toronto, ON – August 14, 2017: Sierra Metals Inc. (TSX:SMT)(BVL:SMT) (“Sierra Metals” or the “Company” - ) today reported revenue of $48.6 million and adjusted EBITDA of $17.6 million on throughput of 454,805 tonnes and metal production of 2.7 million silver equivalent ounces or 23.1 million copper equivalent pounds for the three month period ended June 30, 2017.

Sierra Metals had a fourth consecutive quarter of solid performance in its operational and financial results, aided by stable metal prices and continued production improvements at the Yauricocha Mine. During the second quarter, the Company maintained the significant improvements revenue and adjusted EBITDA realized during the previous quarters. This was largely attributed to the continued benefits being realized from the completion of key aspects of the operational improvements program at Yauricocha. The Company achieved excellent quarter over quarter improvements in Q2 2017 with revenues up 32%, adjusted EBITDA up by $12.1 million, and a decline in the consolidated all-in sustaining cost (ASIC) per silver equivalent payable ounce and copper payable pound.

During Q2 2017, consolidated metal production decreased 3% compared to Q1 2016. The decrease in metal production was due to lower throughput, lower head grades and lower recoveries of all metals, except gold recoveries at Bolivar; and lower throughput, lead and zinc head grades, and silver and lead recoveries at Cusi. This was partially offset by higher throughput, higher copper and zinc head grades, and higher recoveries of all metals, except gold, at Yauricocha.

Brownfield exploration programs remains a key priority at all three mines and the Company is very optimistic that high value tonnage will be added when the Company releases update technical reports for all three Mines in the fourth quarter and in the years to come. Examples of brownfield success can be seen at Yauricocha with the Esperanza, Cuye-Mascota zones, at Bolivar with the Bolivar West and Northwest zones as well as at Cusi with the recently announced Santa Rosa de Lima Zone. When combined with the continued production optimization program, it should lead to substantial growth in production, lower costs, but most importantly in shareholder value.

“Sierra Metals has again delivered value and growth in the second quarter with a respectable financial performance”, commented Igor Gonzales, President and CEO of Sierra Metals. “The Company saw increases in revenue, cashflow and adjusted EBITDA over the same quarter in 2016. The continued solid performance is attributable to the successful operational improvements program at the Yauricocha Mine, continued development of new higher-grade ore zones at Bolivar and the reinterpretation of geology and development of the Santa Rosa de Lima zone at the Cusi Mine which promises to drive increased grade and tonnage in the future.”

He added: “Sierra Metals’ continues to have a very strong balance sheet with the liquidity that allows for continued operational successes, growth opportunities and development that has been planned for this year. The Company is committed to continued brownfield exploration programs, whose success will drive substantial production growth and increase economic returns at all three of the Company’s Mines in the future.”

The following table displays selected financial and operational information for the three and six months ended June 30, 2017:

Q2 2017 Financial Highlights

Revenue from metals payable of $48.6 million in Q2 2017 increased by 32% from $36.9 million in Q2 2016. Higher revenues are primarily attributable to the 10% increase in throughput, the increase in copper, and zinc head grades, and higher recoveries for all metals, except gold, at Yauricocha; and the increase in the prices of silver (1%), copper (20%), lead (25%), zinc (40%), and gold (2%) in Q2 2017 compared to Q2 2016; this was partially offset by an 18% decrease in throughput and lower head grades and recoveries for all metals, except gold recoveries, at Bolivar; and a 54% decrease in throughput and lower lead and zinc head grades, and lower silver and lead recoveries at Cusi.

Yauricocha’s cash cost per silver equivalent payable ounce was $8.49 (Q2 2016 - $9.60), and all-in sustaining cash cost (“AISC”) per silver equivalent payable ounce was $13.47 (Q2 2016 - $14.72) for Q2 2017 compared to the same period in 2016. The decrease in the AISC per silver equivalent payable ounce during Q2 2017 was due to an increase in silver equivalent payable ounces as a result of higher throughput and ore feed head grades from the increase in available production from higher grade zones in the Mine. Also, lower treatment and refining costs were incurred during Q2 2017 resulting from improved terms within re-negotiated sales contracts with our off-takers, which offset higher sustaining capital expenditures.

Bolivar’s cash cost per copper equivalent payable pound was $1.35 (Q2 2016 - $1.02), and AISC per copper equivalent payable pound was $2.49 (Q2 2016 - $1.96) for Q2 2017 compared to the same period in 2016. The increase in the AISC per copper equivalent payable pound during Q2 2017 was due to a decrease in copper equivalent payable pounds as a result of 18% lower throughput due to reduced equipment availability and a lack of water available to be pumped into the plant. 13 new pieces of equipment has been ordered to improve availability at Bolivar including trucks and scoops and started arriving in the second quarter the effects of the new equipment and better availability will be more visible in the latter part of the years production.

Cusi’s cash cost per silver equivalent payable ounce was $20.60 (Q2 2016 - $10.77), and AISC per silver equivalent payable ounce was $49.13 (Q2 2016 - $18.74) for Q2 2017 compared to the same period in 2016. AISC per silver equivalent payable ounce increased due to the decline in throughput which resulted in fewer silver equivalent payable ounces as the Company is currently re-evaluating its development plan at the mine and focusing all efforts on the continued exploration and development of the recently discovered Santa Rosa de Lima zone. The Company has currently reached the actual structure via a ramp and is currently focused on its development and detailed planning to include the material in future mill feed.

Adjusted EBITDA (1) of $17.6 million for Q2 2017 increased compared to $5.3 million in Q2 2016. The increase in adjusted EBITDA in Q2 2017 was primarily due to the $14.5 million increase in revenues at Yauricocha, discussed previously.

Cash flow generated from operations before movements in working capital of $17.4 million for Q2 2017 increased compared to $6.2 million in Q2 2016. The increase in operating cash flow is mainly the result of higher revenues generated and higher gross margins realized.

Cash and cash equivalents of $31.1 million and working capital of $5.2 million as at June 30, 2017 compared to $42.1 million and $9.6 million, respectively, at the end of 2016. Cash and cash equivalents have decreased by $11.0 million during H1 2017 due to $25.7 million of operating cash flows being offset by capital expenditures incurred in Mexico and Peru of $(19.6) million, repayment of loans, credit facilities and interest of $(15.6) million, and dividends paid to non-controlling interest shareholders of $(1.7) million. Included in the $25.7 million of operating cash flows were negative changes in non-cash working capital items of $6.0 million due to the increase accounts receivable and decrease in deferred revenue as at June 30, 2017.

Project Development

The Company announced the discovery of a new high-grade oxide zone, referred to as the Esperanza North zone, which is located between the Esperanza zone and Cachi-Cachi Mine at Yauricocha. The Company also announced drilling results demonstrating the extension of the high-grade sulfide zone, referred to as the Cuye-Mascota zone, discovered in November 2016. The new discoveries come as part of an ongoing brownfield drilling program that is testing priority targets at the Yauricocha, and all drilling will be included in an upcoming Mineral Resource and Reserve Estimate report that is expected to be published in the fourth quarter of 2017.

Mine development at Bolívar during Q2 2017 totaled 775 meters. Most of these meters (722) were developed to prepare stopes for mine production. The remainder of the meters (53) were related to the deepening of ramps and developing service ramps to be used for ventilation and pumping.

During Q2 2017, at the Cusi property, mine development totaled 1,551 meters, and 2,026 meters of infill drilling was carried out inside the Mine.
