Cokal Limited (Cokal) is an Australian listed (ASX:CKA) coal company, with interests in coal exploration in Kalimantan, Indonesia and Tanzania. Cokal’s premier project in Indonesia, Bumi Barito Mineral (BBM), covers 19,920 hectares (Ha) and straddles the Barito River. Proving up Coal Resources to the Australian Joint Ore Reserves Committee (JORC) Code standard for early production is their priority.
Initially, it saw 77 million tonnes (Mt) Total Resource comprised of 70Mt Inferred Resources and 7Mt Indicated Resources with 70% coking coal and 30% PCI (Pulverized Coal Injection). Using a Dassault Systèmes Mine Planning app, this estimate has been upgraded to 261Mt, comprised of 10.5Mt of Measured, 13.5Mt of Indicated and 237Mt of Inferred Resources.
Dassault Systèmes Mine Planning app increases Cokal’s productivity by identifying where to drill, saving valuable time and money. Incorporating the information from the initial outcrops, geologists create predictive holes in appropriate patterns, ultimately forming a drilling budget that provides drillers with the anticipated drillhole intersections.
Speaking about Dassault Systèmes Mine Planning app, Cokal’s Exploration and Resource Manager, Chris Turvey, says: “It helps to give you the confidence you need in your data to compile a reliable geological model.”
By identifying where and how deep to drill, Dassault Systèmes Mine Planning app avoids costly and time consuming wildcat drilling, a significant mining cost savings for Cokal. Once geologists receive the borehole information, they can update their data and re-generate the geological model to confirm the intersection location and determine the quality of the coal. Dassault Systèmes Mine Planning app can be used to quickly predict and gauge borehole results to determine the next steps for drilling.
