Located in the Philippines, approximately 200 kilometers north of the capital city of Manila, the Didipio Mine is a significant gold and copper operation. It is geologically classified as both a low sulphidation and porphyry deposit, a combination that contributes to its valuable metal endowment. The operation employs both open pit and underground mining methods to extract ore, which is then processed at an on-site facility with a nameplate capacity of 4 million tonnes per annum.
In 2024, the Didipio Mine demonstrated its production capabilities, successfully processing 3.9 million tonnes of ore. This activity yielded approximately 3 tonnes of gold, 5 tonnes of silver, and a substantial 12.3 thousand tonnes of copper. The processing plant utilizes a combination of gravity separation and flotation methods to recover the valuable minerals, achieving strong recovery rates of 89% for gold and 90% for copper, underscoring the efficiency of the metallurgical process.
The operation is underpinned by robust mineral inventories. As of the latest data, the Proven and Probable Reserves stand at 38.3 tonnes of gold (at an average grade of 0.91 grams per tonne), 80 tonnes of silver (averaging 1.88 g/t), and 150 thousand tonnes of copper (averaging 0.35%). Beyond this, the project holds additional potential as defined by its Measured, Indicated, and Inferred Mineral Resources. These resources are estimated at 56.3 tonnes of gold (0.92 g/t), 108 tonnes of silver (1.73 g/t), and 210 thousand tonnes of copper (0.35%). The All-In Sustaining Cost (AISC) for the operation was reported at 1140 US dollars per ounce of gold, a key metric for assessing its economic viability.
