MINE PLANNING & PRODCUTION FOR SILICA DEPOSIT – PERTAMISI
Introducing the Vertical Direct Transfer Method to extract the silica alluvial while maintain the environment. Proposing the production optimization based on reserves, geometry and economic approaches. This course also discussed the Vehicle Route Problem and Open Vehicle Route Problem.
RESOURCE ESTIMATION & GEOSTATISTICAL ANALYSIS FOR COAL DEPOSIT – PT. KAGARA GLOBAL ENERGY
This project carried out the geological modelling, statistics & geostatistics analysis, variogram construction, quality distribution and resource classification for coal deposit. The database consisted of 259 holes with a total depth of 19,919 meter. These holes intercepted 15 seams. The geological modelling was constructed that was constrained by sedimentation parameters and tectonic impacts. While, the […]
ANALYSIS OF THE POTENTIAL NICKEL COMMODITIES AS SUBJECT OF FUTURE CONTRACTS TO BE TRADED ON THE FUTURE EXCHANGES IN THE FRAMEWORK OF ESTABLISHING PRICE REFRENCE – COMMODITY FUTURES TRADING REGULATORY AGENCY (BAPEBTI), MINISTRY OF TRADE
This project was requested by Commodity Futures Trading Regulatory Agency (BAPEBTI) under Ministry of Trade, Government of Indonesia to investigate the potential of nickel commodity than can be traded on the future exchanges based in Indonesia. this study was carried out based on the quantitative approaches. These results suggested that the nickel project is feasible […]

CAN INDONESIA CONTROL THE GLOBAL NICKEL MARKET?
This question is often escalated since Indonesia has been recognized to share over 50% of global primary nickel production in 2023. If yes, how it happens. In over last decade (2010 – 2017), Indonesia just contributed less than 20% of global primary nickel production. However, since several smelters were commenced in 2018, Indonesia has reached […]
Exploration & Geological Services
Grabuma offers the exploration and geological services to optimize costs, times and risks in seeking, delineating and determining the mineral deposits (geometry and quality). Our strategy is started by reviewing the regional geology and historical data on the location before we design the best exploration strategies. The exploration program is purposed to seek the most […]
Ore Body Modelling & Mineral Resources Estimation
We create the 3D geological modelling using the explicit model based on the geological interpretation of mineral deposits. This task is supported by experiences and knowledge to design each geological sections to interpret the mineralized zones combining the surface mappings, underground mappings and the drillhole intercepts. With very limited data, we develop the implicit models […]
