Abstract

One of technical requirements in renewing mining operation permits, according to ‘Peraturan Menteri Energi dan Sumber Daya Mineral Nomor 34 Tahun 2017’, is the balance sheet of resources and reserves. Before the expiration of the production permit of PT. AKAM, it was then needed to calculate the andesite resource in the operation area of PT. AKAM in Sorong, Papua Barat. The Cross Section method is considered to be the best way to estimate the andesite resource because this method can be utilised to find out the layout of the overburden and mineral. The results highlighted that andesite resource in the operation area of PT. AKAM was approximately 405.780.313 m³, with a cover layer of 498,937 m³. The productivity age of PT. AKAM is predicted to be 49,64 years, with the annual production of 8.112 m³

Abstract

Estimating of nickel resource in block WN-01 PT. Karunia Alam Waigeo, West Papua aim to understand the number of metal tonnages and the direction of the resource dispersion. The study has been done with phases which are literature study, retrieval of drill data (49 bore holes), data processing with Ordinary Kriging (OK) method using GS+ version 70 software, in as much, estimating the resources by means of block method kriging and point kriging. To understand the estimation correlation of grade to composite grade the scatter diagram analysis was used. Based on scatter diagram (scatter plot) for block kriging method correlation coefficient of 0,8843 is obtained while for point kriging method is 0,8935. With the standard deviation of 0,3280, the point block kriging method has obtained 18.630,08 tons of nickel while for point kriging method with 0,4060 of the standard deviation the nickel obtained is 18.875,41 tons.
