TORONTO, Feb. 15, 2013 /CNW/ - Sierra Metals Inc. (TSX-V:SMT) (BVL:SMT) ("Sierra") ("the Company") is pleased to announce the filing of Sociedad Minera Corona S.A.'s ("Corona") 2012 fourth quarter and annual unaudited financial statements and management's discussion and analysis. The Company holds an ownership interest of 81.8% 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.

Daniel Tellechea, President and CEO of Sierra Metals, commented "Sierra is pleased with the continued success of the Corona acquisition. Corona is a low-cost producer with strong cash flow generating capacity that has added substantial value to the Company since May 2011. The Yauricocha Mine will continue to be an integral part of the Company's operations as the development of the new shaft at depth will lead to increases in production over the coming years".

The following table sets out select unaudited financial information for the fourth quarter and year ended December 31, 2012 and 2011:

Corona's Financial Highlights (US$000)

• Net income of US$7,455 or US$0.207 per share for the fourth quarter of 2012 compared to US$15,883 or US$0.442 per share for the same period in 2011. Net income of US$47,660 or US$1.325 per share and US$63,444 or US$1.763 per share, for the year ended December 31, 2012 and 2011, respectively.
• EBITDA of US$15,013 for the fourth quarter of 2012 compared to US$19,667 for the same period in 2011. EBITDA of US$81,392 and US$93,569 for the year ended December 31, 2012 and 2011, respectively. The main drivers for the decrease in EBITDA include: a decrease in revenue per tonne due to lower copper production, higher cash costs resulting from increases in production levels and higher costs of consumables and third party services.
• Operating cash flows of US$14,248 for the fourth quarter of 2012 compared to US$15,351 for the same period in 2011. Operating cash flows of US$50,852 and US$68,275, for the year ended December 31, 2012 and 2011, respectively. In addition to lower EBITDA levels, the decrease in operating cash flows during 2012 was driven by higher taxes resulting from the new mining tax law established in Peru during the fourth quarter of 2011.
• Income taxes of US$4,650 for the fourth quarter of 2012 compared to US$8,252 in the same period of 2011. Income taxes of US$30,385 and US$27,836 for the year ended December 31, 2012 and 2011, respectively.

Revenues of US$149,566 and US$144,603, for the year ended December 31, 2012 and 2011, respectively. Despite a revenue increase of 3% during 2012, the revenue per tonne decreased as a result of a change in Corona's revenue mix.
• A negative silver ("Ag") cash cost of US$15.46 per ounce ("oz") at Yauricocha in the fourth quarter of 2012 compared to a negative cash cost of US$15.78 per oz in the same period of 2011.
