The Project is located within the industrial facility of Rio Tuba Nickel Mining Corporation (RTNMC) in Brgy. Rio Tuba, Bataraza, Palawan.
Since 1977, RTNMC has been mining saprolitic nickel ores selling them to ferro-nickel smelters abroad. In more than 25 years of operation, it also generated mine wastes of about 25 million tonnes. Called low grade limonitic mine wastes, these are stockpiled around the mine area.
CBNC will process these stockpiles using the technology called HPAL or high pressure acid leach.
