Geologists please
This is question mostly for Carl (Renormalised) and any geologists or opal miners in this forum. Long long time ago when there were no speed limits, no RBT, no political correctness, when you could drive around with your Ute loaded with Gelignite, Nitro Phil, Cordex, detonators and fuse, when you could walk in Pub with your rifle and have beer without rising anyone’s eyebrow I was mining for opals in Coober Pedy. That was the time when throwing a stick of Gelignite with lighted fuse (without the detonator) in Pub’s Bar was consider “funny”. That was the time when Melbourne Mafia used to track Moonshine in to Coober Pedy in 2000l trailers disguised as fire tenders. That was the time when local police force amounting to two if I remember correctly used to lock up all drunken Abos (native Australians) and send them next morning to do noodling. Because of incredible eyesight or ability to spot difference of native Australians Police Sergeant finished up with nice purse of opals in exchange for smokes, beer and freedom.
Anyhow, enough rambling about past and long gone by. My question is - old timers used to say – when your drive (horizontal tunnel blasted and dug from your vertical shaft) intersect the Slide(kind of rusty brown line running thru white sandstone – I think minor fault line) you will find opal on other side. Is there any justification for this?
