In a statement, Timmins Gold chief executive Bruce Bragagnolo, said: "2011 was an extremely successful year for the company on several fronts. The company aggressively reinvested cash flow from operations in a highly successful drill program over the previous 18 months, resulting in a 71 percent increase in the proven and probable reserves, along with an expansion of the crushing unit from 12,000 to 18,000 tonnes per day."
The company said it will carry on to self fund further expansions over the ensuing year to 32,000 tonnes per day, which will bolster production to about 130,000 gold ounces a year.
In addition, the company wrapped up a drill program of 205,000 metres which increased measured and indicated resources to 1.57 million gold ounces and inferred resources to 1.35 million ounces of gold, it added.
The Mexican-focused miner also said on Wednesday it purchased an extra 700-hectares at La Chicharra for leach pad expansion and received permits for the expansion.
