- Geological resource classification and estimation, including preparation of resource reports in accordance with SNI, Peraturan Menteri ESDM, and JORC standards.
- Assessment of geological risks, including geotechnical and hydrogeological aspects.
- Classification and estimation of mineral reserves in accordance with ESDM standards, including preparation of reserve estimation reports.
- Development of long-term mine plans optimized for budget, production forecasting, and resource constraints.
- Optimization of mining sequences, including pit design, road layout, and infrastructure placement.
- Updating of block models for deposits and pits upon receipt of new or additional data.
- Recording, systematization, and analysis of discrepancies between block model / reserve estimates and actual production, with development of improvement actions.
- Coordination with Geological and Mining divisions to ensure accuracy and necessary adjustments in mining operations, including methodological guidance and oversight of medium- and short-term mine planning.
