United States Antimony receives environmental permit for Puerto Blanco mill

United States Antimony Corp. said. Nov. 29 that its United States Antimony de Mexico S.A. de C.V. unit received environmental approval from Mexico's Secretariat of Environment and Natural Resources for the construction of a cyanide leach plant for the Puerto Blanco mill in Guanajuato, Mexico.

The cyanide leach plant will recover gold and silver from the flotation mill tailing of the Los Juarez gold-silver-antimony deposit in Queretaro, Mexico.

The company has begun construction of the leach circuit, with the cyanide leach plant building and the plastic membrane in the tailings pond as part of the project's initial work. Pilot production for the plant will begin next year.
