BNAmericas reported that Vancouver-based tailings processor Amerigo Resources has resumed operations at its Minera Valle Central complex in central Chile's region VI. The company said that the plant is once again in production, processing both fresh and old tailings from the El Teniente mine. Amerigo halted operations on June 6th 2011 as a result of the ongoing strike by 11,000 contract workers at state copper producer Codelco's El Teniente division. Amerigo's sole business is to process copper and molybdenum tailings from El Teniente, which is by far Codelco's most profitable division.
