Small business owners and workers owed millions of dollars by an iron ore mine that has gone into administration are criticising the Northern Territory government for allowing it to keep operating for months without enough money to pay its bills.Iron ore mining company Nathan River Resources (NRR) has gone into voluntary administration, with ASIC documents showing it owes more than $360 million in debts, including in unpaid wages and royalties.The Singapore-owned mine on the Gulf of Carpentaria has collapsed and reopened several times over 13 years.The company's debts include $18 million to contractors, $4.5 million to the Australian Tax Office, $2.4 million to Aboriginal traditional owners — paid through the Northern Land Council (NLC), $6.9 million in NT government royalties, $2 million in NT government payroll tax, and at least $900,000 to employees in wages.It also owes $124 million to another miner, Glencore Nathan River Resources used Glencore's Bing Bong port near Borroloola to export its ore.While Nathan River Resources owes governments and big companies millions of dollars, some of the biggest impacts are being felt by hundreds of Northern Territory, Western Australian, Queensland and national businesses — some of them small and family-owned — that have been left out of pocket.Darwin firm A.M
