Codelco to deploy lower carbon explosives in copper mine
The new explosives are expected to cause a significant reduction in emissions at the Radomiro Tomic mine.
Grupo Mexico and miners at its U.S. copper mining unit Asarco agreed to extend their existing contract for two more years, the Mexican company said in a statement on Tuesday.
The contract covers 2,100 workers at Asarco’s operations in Arizona and Texas and will now be valid until 2013.
