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 IUP OP contains a 30-meter high above surface outcrop dome and 120-meter beneath deposit of Graywacke rock aggregate that is to be extracted using drill and blast quarrying methods. Our objective is to safely and cost-effectively meet business requirements through the appropriate management of risks by providing our workforce with a safe working environment.

The name Kaltara Batu Konstruksi stems from:

    ourhistory

    Our History

    It all started in early 2016 when our founder and President Director, Mr. Josh Sleiman, came to the realization that Indonesia was facing a major problem with the supply shortage of raw construction materials, and thus the goal was set: to become the leading aggregate materials company, focusing on the acquisition of greenfield lands with economically minable aggregate products for domestic and international markets.


    KBK was incorporated in late 2016 to obtain a WIUP (Mining Business License) on a land area suitable for the development and operation of an aggregate quarry, located in the Malinau Regency, North Kalimantan.
