Sierra Metals continues to see a positive impact from the operational improvements program with significant improvements in Revenue and adjusted EBITDA combined with lower costs in the fourth quarter at its Yauricocha mine in Peru. The Company completed key aspects of the operational improvements program this quarter including the transitioning to a higher capacity hoist at the Mascota shaft and has returned to normalized operations. Sierra Metals achieved remarkable year over year improvements in the fourth quarter with revenue up 164%, adjusted EBITDA up 1,093% and the all in sustaining cost ("ASIC") per silver equivalent payable ounce lower by 25% to US$12.51.  The Company's continued emphasis at Yauricocha will be to focus on the production of higher value ore, further cost reductions where possible and optimization to improve the Company's production, operating margins and cash flow generation.

"I am extremely pleased with the very successful operational improvements program completed at the Yauricocha Mine and how that has translated into near record production levels in the fourth quarter complimented by remarkable improvements to revenues, adjusted EBITDA and cashflow for the Mine." stated Mark Brennan, President and CEO of Sierra Metals. "Corona's operating margins and cash flows have been positively impacted by the Company's focus on the processing of higher value ore. This can be seen by an increase of 69% in silver equivalent production year over year which has led to significant increases in revenue and adjusted EBITDA and a lower AISC per silver equivalent payable ounce. Corona's Q4 near record production level was the second highest in the 68-year history of the Mine. This was still accomplished despite a planned 25-day shutdown in November, to complete the transition to a new, higher capacity hoist located on the 720 level at the Mascota shaft (please see press release dated September 12, 2016). 

He continued, "Corona's balance sheet continues to improve and the Company has strong liquidity.  Management is optimistic that we will realize continued mineral resource growth from our brownfield exploration programs including the Esperanza zone, the Cuye-Mascota zone as well as several other high value targets within the mine complex.  When combined with significant operational improvements already completed at Yauricocha, we expect this will provide for substantial growth generation in the future."

Corona's Financial Highlights for the Three Months and Year Ended December 31, 2016

• Cash and cash equivalents of $36.9 million as at December 31, 2016 compared to $21.8 million as at December 31, 2015. Cash and cash equivalents increased by $15.1 million which was driven by operating cash flows of $25.1 million, proceeds received from credit facilities of $8.8 million, partially offset by capital expenditures of $11.6 million, debt and interest payments of $4.5 million, and dividends paid of $2.7 million.
• Revenues of $31.9 million for Q4 2016 compared to $12.1 million in Q4 2015 and revenues of $97.3 million for the year ended December 31, 2016 compared to $80.1 million for the same period in 2015. The increase in revenues was due to a 22% increase in tonnes processed, higher head grades for silver, copper and zinc, higher recoveries for all metals, except gold, and the increase in the prices of silver (14%), copper (9%), lead (23%), zinc (59%), and gold (23%).
• Cash cost per silver equivalent ounce sold at the Yauricocha Mine of $7.29 for Q4 2016 compared to $9.45 for Q4 2015 and $7.77 for the year ended December 31, 2016 compared to $7.01 for the same period in 2015. All-in sustaining cost ("AISC") per silver equivalent ounce sold of $12.51 for Q4 2016 compared to $16.70 for Q4 2015 and AISC of $13.11 for the year ended December 31, 2016 compared to $13.17 for the same period in 2015. The decrease in AISC during Q4 2016 was due to the increase in throughput and metal production from the mine. The AISC during the year ended December 31, 2016 is consistent with the same period in 2015 as the restructuring process at Yauricocha has reached its completion and the mining costs have stabilized and should remain consistent going forward.
• Adjusted EBITDA of $14.9 million for Q4 2016 compared to $(1.5) million for Q4 2015 and $35.0 million for the year ended December 31, 2016 compared to $24.9 million for the same period in 2015. The increase in adjusted EBITDA for Q4 and the year ended December 31, 2016 was due to the increase in plant throughput, metal production and revenues, discussed above.
• Operating cash flows of $14.8 million for Q4 2016 compared to US$(5.1) million for Q4 2015 and $25.1 million for the year ended December 31, 2016 compared to $14.6 million for the same period in 2015. The increase in operating cash flows for the three months and year ended December 31, 2016, compared to the same periods in 2015, was primarily due to the increase in operating cash flows discussed previously.
• Net income of $8.0 million, or $0.22 per share, for Q4 2016 compared to a net loss of $(4.4) million, or $(0.12) per share, for Q4 2015. Net income of $17.2 million, or $0.48 per share, for the year ended December 31, 2016 compared to $7.5 million, or $0.21 per share, for the same period in 2015.
