What a flood of information!!!!!!
So all of these are servicing the upper Barito River Mines and not servicing the local mines. Note no land based delivery system.
So for people that doubt the logistics, all these companies are following the BHP Logistics System (Mine) and really the pioneer MGM that gave us the starting point. in late 2004, I investigated MGM for Xstrata and then joined BHP Maruwai Project. So I knew what worked in a fundamental way.
So the neat one looks like my Teluk Timbau that was designed for BHP and now Adaro's ISP dedicated to HCC from Lampunut Mine in Maruwai CCoW project. I'll dig out drawings and photos I took from helicopter.
