Tiaro Coal has entered voluntary administration.
The miner has four major projects, all of which are located in Queensland, as well as another located in East Kalimantan, Indonesia.
It has appointed Martin Madden, David Winterbottom, and Rahul Goyal of KordaMentha as its administrators.
It comes after the company commenced legal proceedings against Hudson Resources in an attempt to seek the return of its books and records, after administrative services Hudson were providing ceased last year.
According to Hudson it was retaining the books as Tiaro owed money for services rendered.
