Located in the far NW of N.S.W. at the intersection of Kidman Way and the Barrier Highway, Cobar's main activity is mining. One of the oldest, Peak Gold Mine was opened in 1896, and the CSA Mine is one of Australia's highest grade copper mines.
Open cut mines are a great aid to visual navigation and can even be flown into in a helicopter. It may be possible in a STOL bush aircraft, thought that's something I have not attempted (yet).
