Geologist at PT Masindo Intienergy Perkasa (2022-07 – 2023-04)
Company coal concession which focus on port rental and mining coal production
- Finding the new prospect area that was previously mining concession, this land just remnant of an old mine and only relied on jetty rental,then using touch core drilling system,resulting in a reserve 120.000 tonnes of coal with qualty <7000GAR.
- Presenting the coal model design to the mine plan engineer for the pit design creation as a reference for the first cut of mining contractor,one week faster then the one-month timeframe given.
- Providing an area for new pit in the former mining site,which has been mine out using the infill drill method,resulting in an additional reserve 10.000 tonnes of coal.
- 30% exploration budget efficiency by hiring a driling team and purchasing drilling equiment ourselves without involving third parties as before.
- Assisting the operation team by supervising the contractor to ensure their plans align with the weekly and monthly design for minimising deviations between the plan and actual.
