OceanaGold Corporation, an Australian-Canadian company, is one of dozens of transnational mining companies in the Philippines that have been reaping profits by mining gold, silver, copper, and other minerals. Its underground Didipio gold and copper mine in the Northern Luzon province of Nueva Vizcaya started open-pit commercial production in 2013. It continues to operate despite a suspension order issued on February 14, 2017 by then-Philippine Secretary of Environment and Natural Resources (DENR), Gina Lopez.
