The Martabe Gold Mine utilises the ‘open pit’ method of gold and silver mining, where the pits are kept shallow due to the hilly topography. Three pits are currently operational: the Ramba Joring Pit, the Barani Pit and the Purnama Pit, which began operations in 2018, 2016 and 2011 respectively.
Mining operations are located in an elevated hilly area bordering the Batangtoru Forest. The support facilities for the mine are mostly located in a lowland area adjacent to the trans-Sumatera highway. The surrounding area includes native forest, rubber and oil palm plantations and rice paddies, with nearby rural villages and townships.
Ore is mined from shallow pits of the mineral-rich hills of the Martabe Gold Mine. In 2018, mining at the Tor Ulu Ala deposit was approved. Waste rock or overburden from the pits is placed in the Tailings Storage Facility (TSF) embankment rather than in waste dumps as is the case in most other mines.
During 2022, Macmahon has commenced the construction of the new tailings dam at the Martabe Gold Mine.
Ramba Joring Pit
Due to the hilly topography and location of its mineral resources, the Ramba Joring Pit is divided into the North and South regions. The areas are in various states of operation, with the northern part being completely operational and wide open. In contrast, the southern part is still in the process of widening.
