Mining & Milling Operations
Construction of the new cyanidation mill has undergone several improvements in recent years. Most recently, the plant was further upgraded in 2015 with the installations of a new 12' x 24' ball mill, tertiary crusher, two vibrating screens and a series of conveyor belts. In 2016, the Company began on the permitting and engineering work for a new roaster to reprocess all of the above ground tailings. The Company expects the new roaster to be full operational by mid-2018. Once in full production, the Company expects to recover an additional 1.5 million ounces from the reprocessing of above ground tailings.
A fully functional 1,000 tpd flotation mill is also located at La Encantada. Historically, this flotation mill was the primary method of silver production over the past 30 years; however, with the cyanidation plant now operating at full capacity, production of lead concentrate through the flotation circuit was suspended in June 2010 and the circuit is currently in care-and-maintenance.
