The Ragged Hills East Mine can be located from the Telfer Mine road in the Gregory Ranges. Look for building foundations on the northern side of the road, next to a creek, and follow a track 200 metres in a northerly direction. The writer visited the mine in the late 1970's and in 2012. The processing plant and various mining equipment from when it was abandoned in 1959 still exists, slowly rusting away. It makes for a facinating visit. Apart from the ore carts which are gone, the rest remains from the two visits. Please keep it that way for others to enjoy.

The writer could only see massive galena, which is abundant. It is hosted by two quartz filled faults, in a north-west to south-east direction, along the top of the ridge for 30 metres. After mining, this forms a 46 metre deep chasm along the top of the hill. A short tunnel extends from the processing plant through the side of the hill to the chasm. Please be careful, as common sense is the only safety measures here. The country rock is sheared basalt, tuff, and carbonate rocks of the Kylena Formation.


Photographs for the mine are incorrectly listed under the Lightning Ridge location (at the time of writing).
