Welcome, what would the choice of fuel used underground? Also could a fellow buy one of these gems in its natural state? Good luck.
warnie,
Nice to see you here! I would so love to visit your country some day! I guess it's on my bucket list.
Been hanging around the US for long time. My travels finally took me clear to China, where I got distracted and had to import my wife. Now I've got a new neighbor with a wife from Australia. It has rekindled my thoughts of your fine country.
Love to heart more about the opal mine.
well debating between electric single ph motor or diesel with extraction fan over a hole and any thing is possable as far as a gem is concerned my partner has a display for the next two weeks at moodys jewlers in tulsa .but send me a private email to blackridge2@bigpond.com and we can discuss your needs
