United States Antimony Corp. said Sept. 10 that it invested considerable capital to increase the production of antimony, gold and silver from its Mexico-based operations.
The company noted that it closed in August a member interest and share capital agreement with Great Lakes Chemical Corp. and LANXESS Holding Co. US Inc., which paid US$1.5 million to dismantle and transport equipment, and carry on cleanup efforts at an antimony plant in Reynosa.
The equipment will be used at all of the company's mines and plants in Mexico as well as at operations in Montana and Idaho.
The company also reactivated the main drift at its Wadley mine in San Luis Potosi by cleaning up waste, and provided a primary power line and transformer to run a 200-horsepower compressor that will allow the use of pneumatic chipping hammers in the mine. These initiatives could double production.
In addition, the Santa Monica drift at Sierra de Guadalupe in Zacatecas will be restarted, while a buying program will be launched for the purchase of direct shipping ore for the Madero smelter.
The construction of a cyanide leach plant for the Los Juarez gold-silver-antimony plant will allow pilot testing to start during the fourth quarter. The company said it anticipates to resume the installation of a 400-ton mill at Los Juarez.
When installed, the equipment from the Reynosa plant will increase the capacity of the Madero smelter to approximately 30 million pounds per year of antimony oxide.
CEO John Lawrence said he expects all of the properties to be producing by the end of the year, resulting in increased revenue.
