The KBK Quarry Project (KBK) is located in Malinau Regency, North Kalimantan Province, and will be one of the leading suppliers of hard aggregates in Kalimantan. The project currently holds roughly 72 million tonnes of mineral resources (JORC, 2012), which will increase by an estimated 50-80 million tonnes by mid-2023. The rock at KBK is known as "Greywacke," and the deposits are to be extracted using conventional drill and blast quarrying methods. Our objective is to safely and cost-effectively meet business requirements, which we will achieve through the appropriate management of risks and by providing our workforce with a safe working environment.
Our operations are part of a fully integrated Aggregate Business Unit, of which all operations are critically interdependent. In this environment, effective business planning, appropriate design, compliance to business processes, and an ongoing focus on cost optimization are paramount. Our ability to extend the life of this asset is closely linked to the effective application of forward planning, real time performance analysis, cost reduction, and efficient capital deployment.
