Although mining has started at five faces at the Los Juarez property, USAC does not claim any reserves.

Furnace capacity at the Madero Smelter in Coahuila is being expanded to handle the flotation concentrates.

John Lawrence, CEO, commented, “USAC produced 204,985 pounds of antimony metal in Mexico in 2011 while awaiting the start-up of mining at Los Juarez and the completion of the flotation mill. The Company has another 500 ton per day mill in Montana that is being prepared to increase capacity in Mexico should it be warranted.
