Opal mining 10 m to 30 meters underground most opal mining methods are shaft and tunneling methods . Tools of the trade one small pick and shovel, lots of rough or uncut opals are never found because of the lack of bright electrical lighting will limit any color which is seen by the naked eye in the face of the digging drives. You have to have 2 of 500 W lights on the face where you’re working and as long as you stop working and have a bit of a pick at trace you see like nobby ,dog stones which are basically solid sandstone mixed among the clay. The secret is patients and work slow and not break valuable opals when you do come across material that stones can form in, also buy one hand held windless for a quick prospect this is a handle and physical device which is connected by steel cable to a bucket at the bottom of the shaft. Underground a Chinese style wheel barrow is often preferred over a Western-style barrow by many miners to move clay and over burden soil etc”an maybe if lucky gemstones.

Opal mining with small petrol generator allows for good bright lighting of the face of the digging, where a air compressors on the surface of the claim allowed the gem hunter to use jackhammers to breakdown and remove the clay, which then can be brought to the surface by a hoist driven by a small engine .
The jackhammer is not used a lot these days by the guys and companies only to bell out at the bottom of a newly drilled 3 foot shaft . The pipes of a blower will be fixed to the wall and run down to the bottom,one guy jackhammers enough room to allow a hydraulic winch to lower and assemble the hydraulic underground digger . Mean while always looking for trace such as nobly and seam dog stones and solids.

The only difference between the full-time professional hunter is the big guys remove clay faster with very powerful and large diesel engines , underground hydraulic diggers resembling a back hole can dig out the clay which will be sucked up by a blower through the pipe behind the digger and carry up the pipes to a hopper where the miners truck is parked under it. Electric machines remove clay also along the drives to a 3 foot shaft,where a large electric hoist takes material up the shaft and also automatically dumps the opal clay into a truck parked above ground.
Early explores rarely ever use water for washing the clay which was often stock pile on the lease for months in the hot sun, when dry the miners shovel the clay over screen mesh and old bed frame or whatever they could utilize at the time. Today artesian water which has been cool down and stalled in dams the artesian water lays about 1 kilometer underground the hot artesian spring water is pumped into small agitator and continuously tumbles the clay will turn into silt and wash out of the fine mesh screen allowing only solids to be examined.
