King-King copper and gold mine in Pantukan, Compostela, Mindanao, Philippines

In January 2016, 60 years old Teresita Navacilla was killed. She was a member of the Save Pantukan Movement, a network of indigenous peoples fighting for the right to their ancestral lands and opposing large-scale open pit mining.


The open-pit King-King Copper-Gold Project operated by Nadecor and St. Augustine in Pantukan threatens the rich biodiversity of Southern Mindanao. The environmental group Panalipdan-SMR cited the 2013 NI 43-101-compliant Technical Report and Preliminary Feasibility Study of M3 Engineering & Technology (M3ENG), which clearly warned that King-King mining will affect twelve “vulnerable or critically endangered” species of the 253 native or endemic plant species present in the area, as defined by the International Union for Conservation of Nature (IUCN) Red List and the Philippine National Red List; six species endemic to Mindanao of the 74 bird species present in the area; and a total of 17 mammalian species and 10 reptilian species identified in the area. The report adds that several of the wildlife species found in the region “are listed as near-threatened or vulnerable by the IUCN, while others are protected by Convention on International Trade in Endangered Species (CITES), including 11 bird species, two mammal species and five  reptile and amphibian species. The region is also home to the Philippine eagle Pithecophaga jefferyi, which will be further endangered as a result of these large-scale mining projects. The environmental group Panalipdan- SMR emphasized that the M3ENG report also highlights the impact of the project on the coastal and marine ecosystems in the area which is part of the eastern coast of Davao Gulf. Several species of sea turtles, dolphins, whales, and seabirds live in the area. The sea cow species and all species of sea turtle found in the region are listed as endangered.
