Abstract
In the context of mining, the estimation is an attempt to estimate the value of block or point that expected to approach the true value. An accurate geological modeling will greatly assist in mining minerals that expected production in accordance with the company’s production targets. Therefore, the research was conducted at PT Sinar Asia Fortuna to determine the geological model and resources. The geological modeling and resource’s estimation of massive limestone was done using Indicator Kriging Method. The geological modeling of massive limestone was carried out by using SGeMS version 2.0 and Datamine Studio 3, while the limestone’s resource was estimated by using Datamine Studio 3. This study categorizes the limestone to be 3 types, i.e. massive limestone, vuggy limestone and chalk. The estimation of percentage by using Indicator Kriging Method obtained the distribution of limestone massive proportion of 75%, 23% vuggy limestone and 2% chalk. The resource calculation respectively obtains 130.889.422 tons of massive limestone, 40.139.422 tons of vuggy limestone, and 3.490.384 tons of chalk. Total tonnage for the indicator kriging = 174 519 228 tons
