Interestingly it points out that Minera Antapaccay is one of the first mining companies to implement drilling rig automation successfully on electric-cable powered rigs. It says there are only 9 drilling rigs in the world that are autonomous electric, of which 3 are in Peru at Antapaccay, 3 are in Chile and 3 are in Canada, though these other groups of three are not at single mining operations.
