PT Kaltara Batu Konstruksi (PT KBK) is a Private Limited Liability Aggregate (Rock) Mining Company incorporated in the Republic of Indonesia. PT KBK holds an Operation Production Mining Business License, known in Indonesian as Izin Usaha Pertambangan Operasi Produksi (IUP OP), which is issued by the Indonesian Investment Coordinating Board (BKPM). KBK’s IUP covers a total area of 40 Hectares (400,000m2) in Malinau, North Kalimantan, Indonesia, close to the Malaysian border.
The KBK Quarry Project (KBK) will consist of a 7 Mtpa (at peak production) drill and blast quarry operation with a separate 44-hectare hub area for the processing, crushing, stockpiling, and retail yard. The planned 7km overland conveyor link from the hub to the 32-hectare port will allow for smooth and efficient transportation of crushed materials, and a proposed barge link service to transport the product along the river to domestic and international customers. The KBK port area is approximately 8km northeast of the KBK quarry, close to the township of Malinau.
