Cokal said it hoped to start loading coal at the Krajan Jetty within days.
"Unseasonably low water levels in the upper Barito River have delayed coal loading, however conditions have almost returned to normal," it said.
"Cokal has been continuing to stockpile coal at the Krajan Jetty in anticipation of improved river conditions.
"Coal will be transported to the BBM permanent jetty at Batu Tuhup where it will be stocked.
"Initial Infrastructure to handle coal unloading, stock piling and loading onto larger barges at Batu Tuhup jetty is in place."
Cokal said coal stockpiled at Batu Tuhup Jetty would be sold in the domestic market under the existing offtake agreement with PT Sumber Global Energy as per the underlying contractual terms.
