VANCOUVER, April 30, 2015 /CNW/ - Sierra Metals Inc. (TSX:SMT)(BVL:SMT) ("Sierra Metals" or the "Company") announces the filing of Sociedad Minera Corona S.A.'s ("Corona") unaudited Financial Statements and Management Discussion and Analysis ("MD&A") for the first quarter of 2015 ("Q1 2015"). The Company holds an 81.8% interest in Corona. All amounts are presented in thousands of US dollars unless otherwise stated and have not been adjusted for the 18.2% non-controlling interest.

Corona's Financial Highlights for the Three Months Ended March 31, 2015

• Revenues of US$ 22.6 million for Q1 2015; and
• Cash cost (recovery) per silver payable ounce of US$ (7.40) at the Yauricocha Mine for Q1 2015.

"Corona continues to report strong results again this quarter with a 2% increase in ore throughput while maintaining high levels of metal production and a strong balance sheet" stated Mark Brennan, President and CEO of Sierra Metals. "Higher silver head grades and higher recoveries mitigated the decline in metals prices and have resulted in another quarter of positive operating cash flow. Corona continues on the path to meet its production guidance for 2015 by remaining a low cost producer while continuing to demonstrate the Yauricocha mine's full economic potential."

Corona's Financial Highlights for the Three Months Ended March 31, 2015

• Net income of US$ 4.7 million or US$ 0.130 per share for Q1 2015 compared to US$ 6.2 million or US$ 0.172 per share for the same period in 2014;
• Revenues of US$ 22.6 million for Q1 2015 compared to US$ 27.9 million for the same period in 2014. The decrease in revenue was mainly due to the decreases in the prices of silver, copper, lead and gold in Q1 2015 compared to Q1 2014 of 17%, 16%, 15% and 5%, respectively. This was partially offset by a 2% increase in plant throughput and higher head grades and recoveries of silver which resulted in a 25% increase in silver payable ounces;
• Cash cost (recovery) per silver payable ounce of US$ (7.40), at the Yauricocha Mine, for Q1 2015 compared to US$ (21.11) for the same period in 2014. The increase in cash costs during Q1 2015 was due to the reduction of by-product credits which were the result of the lower metal prices discussed previously, lower zinc head grades, partially offset by the increase in silver payable ounces during the quarter;
• Adjusted EBITDA of US$ 10.3 million for Q1 2015 compared to US$ 12.9 million for the same period in 2014. The decrease in adjusted EBITDA for Q1 2015 is mainly due to the decrease in revenues previously discussed;
• Operating cash flow of US$ 4.6 million for Q1 2015 compared to US$ 8.8 million for the same period in 2014; and
• Cash and cash equivalents of US$ 29.0 million as at March 31, 2015 compared to US$ 28.7 million as of December 31, 2014. Cash and cash equivalents increased by US$ 0.4 million which was mainly driven by US$ 4.6 million of operating cash flow, offset by US$ 2.8 million of capital expenditures and US$ 1.2 million of financing activities.

Corona's Operational Highlights for the Three Months Ended March 31, 2015:

• Total tonnes processed of 219,969; a 2% increase over Q1 2014
• Silver production of 549,973 ounces; an 11% increase over Q1 2014
• Copper production of 1.7 million pounds; consistent with Q1 2014
• Lead production of 11.7 million pounds; consistent with Q1 2014
• Zinc production of 10.5 million pounds; a 18% decrease over Q1 2014
• Gold production of 1,587 ounces; an 8% increase over Q1 2014
