Construction of the US$76.6-million open-pit mine will begin in the second quarter, with the first silver pour slated for late 2006. The mine is expected to produce around 5 million oz. silver at a cash cost less than US$3.25 per oz. in each of its eight years of operation. Recovery rates for both silver and gold are expected to exceed 90%.
At the end of 2004, Alamo Dorado had a proven and probable reserve of 11.6 million tonnes grading 118 grams silver and 0.34 gram gold per tonne, or 44 million oz. silver (almost 40 million of those ounces were in the probable category); 3.9 million tonnes grading 72 grams silver and 0.27 gram gold were in the measured and indicated category; and 518,000 tonnes at 79 grams silver and 0.34 gram gold were inferred.
The 15-to-18-month construction period will see the erection of a primary crushing circuit, semi-autogenous grinding mill, ball mill, and conventional cyanide leaching circuit. Also, a tailings treatment plant will be built to recover sodium cyanide used in processing.
