Castle Mountain Mine Earthworks & Pad Construction
This project involves construction of an approximately 3M SF leach pad to process 12,700 tons of ore stockpiled from previous operations per day. As earthworks contractor, P&J is performing all heavy civil activities, including clearing and stripping, topsoil removal, excavation and embankment activities, and installation of HDPE pipe systems during construction of the leach pad. P&J will then haul 14.3M yards of ore to the pad over the next four (4) years.
