The site has been selected for the jetty to load barges at Batu Tuhup, approximately 1.5 km from the temporary jetty site BBM has contracted to use for the first year.

This site has more than 300 m frontages on the Barito River and at this location has more than 2.5 m water depth all year long. A preliminary layout has been completed to be detailed when the topography and bathymetry survey results are available. The barge loader will be capable of 1000 tph.

A contractor has been engaged to undertake a LiDAR survey of topography and a second contractor to undertake a bathymetric survey, both to be done week beginning 16 August 2021 once the current COVID restrictions PPKM Level 4 is complete.

The downriver ISP will be at Buntok. A LiDAR topographical survey of this site will be conducted as soon as the Batu Tuhup survey is completed.

Progress on the road from 52 km into Pit 3 at BBM has progressed, with a number of bridges and culverts being constructed. Additional equipment has been mobilised to increase the rate of this progress.

The remnants of old bridges are dismantled, any reusable logs recovered, and a new bridge constructed. Then the road is cleared to access the next bridge. Many of the old bridges failed because geofabric was not used to cover the logs before placing road construction fill over them. Some significant cuts have been excavated.
