Key facts about this geosite:

• The Pioneer Sandstone contains gastropods (snails) and rhynchonellid brachiopod fossils.
• The fossils are of Middle Ordovician age

 

Geosite Description: The Newall Creek area contains many historic gold workings especially the Harris Reward gold mine (Julen, 1981), the first mine in the area, predating the Mt Lyell copper mines. Workings include pits and shafts which are largely collapsed and partly obscured by the rainforest and part of a historic pack track. The workings exploited lode gold in quartz veins in the Cambrian volcanics plus some alluvial gold weathered from the lodes into gravels and sands. White quartz scattered around the mines is a remnant of the mineralised veins. There are other workings west of the road, but people should venture into these areas only with great care.

 

The first report on the mine (Twelvetrees, 1900; Collins, 1974) describes two tunnels (24m and 10m long), and two shafts (12m  and 11m  deep). The  shafts  were later  extended  and opened  out  by  the  Coronation  Gold  Mining  Company  which  took  over  the  mine  in 1902  but  operations  apparently  ceased  during 1905.  Production from  the  mine  was at least 1.480 kg Au  from 109.6  t of lode quartz. The gold occurs with galena in discontinuous quartz  veins  which  are  parallel  to  the  strike  and  dip  of  the  schistose and  porphyritic country  rock,  and  were  reported to  be  5-12 cm  wide.
