The Trisula Kencana Sakti (TKS) mine is comprised of TKS Concession and TKS Ampah Concession.
The TKS Ampah Project is designed as a source for supplying coal to power and cement plants. TKS Ampah Mine was commissioned in 2018 at the South Pit. Mine was placed on care and maintenance in 2019.
Salva Mining has reviewed the mine plan and performed cross-checks to ensure that the operation is practical and achievable. The mine plan targets a production rate of 0.2 Mtpa (at the North Pit) for the remaining mine life from 2024 to 2026. |

Summary:
Trisula Kencana Sakti Concession
The concessions lie in the Barito Basin of Central Kalimantan. The Barito Basin is defined by the Meratus Mountains to the east and separated from the Kutai Basin to the north by a flexure parallel to the WNW-ESE orientated Adang Fault.
Field Exploration identified lower quality Warukin coal seams in the core of a syncline, grading to higher quality Montalat coal seams toward the outer edges of the structure. The Tanjung Formation geology within the TKS Concessions is less well understood because exploration has been limited to coal outcrop mapping. It is expected that coal seams discovered in the older Tanjung Formation will have a higher calorific value and generally better quality characteristics than the younger Warukin and Montalat coal seams.
The main features in the concessions are a syncline structure over the main deposit area with relatively flat dips and younger sediments in the central part of the deposit and steeper dips in relatively older sediments, around the outer edges. Major faults are interpreted surrounding the deposit and controlling the boundaries of the coal to the north, south and east.
The deposit at TKS Concession contains approximately 19 modelled coal seams of which 4 have been split into upper and lower plies. The cumulative coal average thickness is 14.85 m in 19 seams.
The coal seams dip shallowly in the centre of the syncline to 5 degrees and up to 20 degrees aro ........
Summary:
The Trisula Kencana Sakti (TKS) mine is comprised of TKS Concession and TKS Ampah Concession.
The TKS Ampah Project is designed as a source for supplying coal to power and cement plants. TKS Ampah Mine was commissioned in 2018 at the South Pit. Mine was placed on care and maintenance in 2019.
The mining operation at TKS Ampah uses standard truck and excavator method which is a common practice in Indonesia. Waste material is mined using hydraulic excavators and loaded into standard rear tipping off-highway trucks and hauled to dumps in close proximity to the pits or to in-pit dumps where possible. For the Reserve Statement, it is proposed that contractors will be used for mining and haulage operations over the life of mine.
The purpose of the mine plan was to create a mining sequence that ensures reliable delivery of the coal product to the ROM stockpile from road haulage to the barging point. The mine plan scenario has targeted ramping up production rates for 5 years of mining operation based on the direct input from TKS Ampah. The annual coal supply was optimised based on the minimum required energy of 6,322 kcal/kg (gar) within the mined Coal Reserve tonnage. This plan had to be accounting for the practical mining constraints to ensure the sufficient working room and the dump capacity to accommodate all waste material mined at each stage plan. Monthly and quarterly fluctuations in waste removal, coal exposure and inventory levels will need t ........
Summary:
The average coal quality attributes of the coal seams considered are sufficient to be marketed as a medium CV thermal coal for domestic power generation purposes.
Coal will be sold from the stockpile area in an uncrushed form (as mined), hence no crushing facilities are planned to be constructed at River Jetty for TKS Ampah project. The stockpiles will be the coal selling point where the ownership of the coal transfers from TKS Ampah to customer.
