Endeavour Silver Initiates Major Mine Expansion at El Cubo; Raises Production Guidance and Reduces Cost Guidance for 2015

VANCOUVER, BC--(Marketwired - March 17, 2015) - Endeavour Silver Corp. (EDR.TO) (EXK) (EJD.F) has initiated a major expansion of its El Cubo mine in Guanajuato state, Mexico. The Company plans to ramp up mine output over the next four months from 1,550 tonnes per day (tpd), the current El Cubo plant capacity, to 2,200 tpd.

The additional 650 tpd of mine production at El Cubo will come primarily from the V-Asunción mine area, which has thicker mineralized zones amenable to long hole mining, and the Santa Cecilia mine area, which has narrower but higher grade veins, and will be processed at Endeavour's Bolañitos plant, located 18 kilometres away in the same district, which has available capacity and comparable circuits to El Cubo. Production at Bolañitos will be reduced by a small amount to accommodate more processing of El Cubo ore.

The main reason for the mine expansion is to drive operating costs lower and generate free cash flow at El Cubo by taking advantage of the available plant capacity at Bolañitos. As a result, El Cubo will become the Company's largest mine by metal production. Endeavour received the cooperation of the miners' union at El Cubo last week in finalizing a labour contract that facilitates the mine expansion and helps establish the short- and long-term viability of the mine.

Revised Production Guidance

The Company has revised its silver production estimate for 2015 upwards by 11% to a range of 6.3-7.0 million ounces (oz). Gold production guidance increases by 27% to the 60,000-66,000 oz range, and silver equivalent production is now forecast to be approximately 10.4-11.6 million oz (using a 70:1 silver:gold ratio), as shown in the table below.

Revised Operating Costs

Consolidated cash costs of production, net of gold by-product credits, are now expected to be around $9-$10 per oz of silver in 2015. Consolidated cash costs for silver and gold on a co-product basis should come in around $13-$14 and $900-$975 per oz respectively. The lower cash cost guidance is largely a function of reduced unit costs at El Cubo due to increased productivity related to the mine expansion.

All-in sustaining costs (AISC) net of gold by-product credits, in accordance with the World Gold Council standard, are now projected to be $16.00-$17.50 per oz of silver in 2015. Although the El Cubo mine expansion requires an increase in mine development capital, management was able to reduce some minor capital projects to optimize the AISC. When non-cash items such as stock based compensation are excluded, AISC net of gold by-product credits should pull back to $15.50-$17.00 per oz of silver.
