Here are some photos of:
Boulder opal fields around Opalton, 125 km south west of Winton, Outback Queensland, where we mine our opals.
The Australian "bush" with animals, scenery, pictures of our mining and opal cutting equipment.
Some mining scenes in the open air and some of the tunnels we dug by hand (with electric jack pick).
Those tunnels are on average 12 metres deep underground and 2.5 metres high.
