Rivet Mining Services founder Mark Rowsthorn, who poured more than $30 million into the logistics group, is likely to have had his investments wiped out after the companys lender put the parent company into administration.
RMS emerged out of the ashes of former transport group McAleese, which was also run by Mr Rowsthorn but collapsed in 2017.
Mr Rowsthorn is the majority owner of RMS parent Blondie Trading, a holding company with more than a dozen subsidiaries. They include RMS, which provides bulk haulage services from mines to ports in Western Australia, as well as Rivet Energy, Rivet Energy Aviation, Sunshine Refuellers, SMS Rental and SMS Innovating Mining.
