The Rio Tuba mine site is located in Barangay Rio Tuba, municipality of Bataraza, in the southern tip of the province of Palawan. RTNMC exports saprolite and limonite ore, and provides limonite ore and non-mining services to the adjacent Coral Bay HPAL plant of CBNC. RTNMC also holds an MPSA to quarry limestone that is also used by CBNC.

RTNMC’s host communities -- Brgy. Rio Tuba and Brgy. Iwahig – are among the 22 barangays that comprise this municipality at the southernmost tip of the main Palawan Island. Population data shows that the largest province of the country is home to more than 771,000 people, with over 86,791 of them residing at Bataraza. Palawan is also renowned as home of several indigenous ethnolinguistic tribes and is sometimes referred to as “the cradle of Philippine civilization” because of the great anthropological find at the Tabon Caves in Lipuun Point. RTNMC has identified 48 Indigenous Cultural Communities who are residing around the mine area, 11 of whom are part of the impact barangays, 11 from non-impact barangays within the Municipality of Bataraza and 1 adopted barangay in Municipality of Rizal.

Aside from mining, the other major economic activities important to the province are eco-tourism, agriculture, logging, oil drilling and exploration, and fishing. Palawan is a significant source of fish supply for the country. Tourism is also growing in importance not only because of world-class resorts but also because the Puerto Princesa Subterranean River National Park was declared one of the New 7 Wonders of the World.
