Toronto, Ontario ¨C May 1, 2013 ¨C Sierra Metals Inc. (TSX-V:SMT) (BVL:SMT) (¡°Sierra¡± or the ¡°Company¡±) is pleased to announce that the Company has completed its first quarterly cash dividend payment of $2.5 million, or $.016 per common share (¡°Common Share¡±), to shareholders on April 30, 2013. The Company announced its inaugural $10.0 million cash dividend policy on February 12, 2013 (see press release dated February 12, 2013 here) as a result of substantial production increases and significant cash flows from operations realized in 2012.

Press Release Highlights:

• Sierra paid its first quarterly cash dividend of $2.5 million, or $0.016 per Common Share, on April 30, 2013.
  
• During 2012, Sierra achieved record production from all operations and announced its strongest fiscal year to date with revenues of $179.7 million, earnings (EBITDA) of $83.8 million and cash flows from operations of $60.5 million.
  
• Sierra¡¯s strong cash flows during 2012 were used to pay down the Company¡¯s working capital line in Mexico, complete the acquisition of Plexmar and pay the 2013 first quarter cash dividend payment to shareholders.
  
• The Company is focused on a fiscally responsible growth strategy that will increase shareholder value through increased production. The proceeds of the $44.4 million private placement completed in June 2012 have been allocated to increasing the production profile of the Company¡¯s mines in Peru and Mexico. 
  
• Sierra intends to pay a total cash dividend of approximately $10.0 million, or $0.064 per Common Share, for 2013 and anticipates the announcement of its second quarter cash dividend will take place on or after June 30, 2013. 

Daniel Tellechea, President and CEO of Sierra Metals, commented ¡°Sierra Metals is very pleased to announce its first cash dividend payment to shareholders of $2.5 million. The acquisition of the Yauricocha mine and announcement of commercial production at the Bolivar mine have resulted in record production for the Company during 2012. Additionally, these low-cost, highly profitable mines have also resulted in strong cash flows allowing Sierra to lower its net-debt and enact the new 2013 $10.0 million cash dividend policy.¡±

During 2012, Sierra Metals focused on maximizing operational efficiencies at the Yauricocha mine in Peru and the Bolivar mine in Mexico with 2012 marking the first full year of production at both operations. This resulted in the Company achieving record production with revenues of $179.7 million, earnings (EBITDA) of $83.8 million and cash flow from operations of $60.5 million. Among other things, these strong cash flows were used to pay down working capital loans in Mexico, complete the acquisition of Plexmar and pay the Company¡¯s first inaugural cash dividend. At the end of 2012, the Company had a cash balance of $79.8 million and net-debt of $9.0 million.

The Company is committed to a fiscally responsible growth strategy of increasing near mine reserves and resources while adding value through production growth at all three producing mines. In June 2012, the Company completed a $44.4 million private placement (see press release dated June 7, 2012) with proceeds dedicated to increasing the production profile of the Company by:

1. Accelerating mine development at the Cusi Mine, which announced commercial production of 200 (¡°tpd¡±) tpd on January 1, 2013;
   
2. Doubling throughput capacity at the Piedras Verdes mill (located 6 km from the Bolivar mine) from 1,000 tonnes per day to 2,000 tpd, with an anticipated completion date in the second quarter of 2013; and,
   
3. Developing a new internal shaft and haulage drift in the Central Mine area of the Yauricocha property to access deeper levels of the mine and increase production capacity, anticipated to be completed in late 2015.  

Sierra Metals anticipates the announcement of its second quarter cash dividend will take place on or after June 30, 2013.
