Following on from my post in 20Xs topic on shaft sinking to find depressions and gold traps in the bedrock, I thought Id share some insights into Chinese mining methods in the upper northeast of Victoria around Mitta and Granite flat.
We know from the discovery of chinese artifacts on this point on Snowy creek that they were definitly the ones who did the majority of the work in this area. careful examination after 2003 and 2013 fires revealed old hut sites and other earthworks associated with mining. Chinese coins and the clips (lots) off opium tins were also detected.
Their method of mining was to follow a favourable rock bar that outcropped in the creek, up into the bank on the inside bend and either sink shafts and drive off the bottom to pick up the rockbar and crevises that were richer in gold than the general run of gravel on the bottom, or later on dig ditches and ground sluice the overburden which was very poor in gold.
Some of these shafts are probably 15 to 20ft deep by not much more than 2ft6in wide and 4ft long. The drives off the bottom being just high enough to crouch or sit in. The ground on the bottom 3 to 4 ft consisting of well packed and locked together cobbles and boulders upto the size of a cows head. This was all done with a pick and shovel and bucket for hoisting.
The Pictures below are taken from inside one of these drives looking out.
