Production & Operating Statistics

The Guanajuato silver-gold mines are underground operations using primarily cut-and-fill mining methods. The ore is processed to produce high quality, precious metal-rich concentrate, which is transported to smelters in Mexico and overseas, for extraction of silver and gold.

San Ignacio came in production in June 2014 and in included.

x Metal Production is expressed in terms of silver equivalent ounces, (Ag Eq oz), the formula for which depends on the gold and silver metal prices used in each year and hence are only indicative.
xxCash cost per ounce of silver is a non-IFRS measure used by the Company to manage and evaluate operating performance at each of the Company's mines. It comprises the cost of production, cost of concentrate transportation and the cost of smelter and refining charges, net of the credit from the sale. Refer to the "Non-IFRS Measures" in our MD&A.
xxxIncludes production from San Ignacio.

Mining

The Guanajuato silver-gold mines are underground operations using primarily cut-and-fill mining methods. The ore is processed to produce a high quality, precious metal-rich concentrate.

The Processing Plant is located near the central Cata shaft. It consists of a 3-stage crushing section, producing a (¬ľ in.) fine ore mill feed; a grinding section, consisting of three ball mills operated in parallel and a conventional flotation circuit with a total capacity of 1,200 tonnes per day.
