Runruno Gold Project

Runruno is located in the mineral rich province of Nueva Viscaya. The area has been known to be prospective in gold and other precious metals since the early 1960s. Nueva Vizcaya is a landlocked province located on the island of Luzon, which is the largest and most populous island in the Philippines. The project lies immediately downstream from the village of Runruno.

The mine has been in production since 2016 and is currently the fourth largest operating gold mine in the Philippines with the last few years seeing a significant turnaround in the operational performance of the plant and the mine overall.

Runruno contains gold reserves of 9.94Mt with an average gold grade of 1.35g/t and forecast gold production for 2023 between 78,000-81,000 oz/pa.
