How to find opals Finding Gold 8: https://www.seevid.ir/fa/w/w7bI4uUacRg Gold & Gem locations: http://www.treasuresites.com/treasurebooks.htm Finished examples: http://www.ebay.com/usr/4-matt1 Opals occur most commonly around basalt deposits, though they can be a mineralized gel replacement for wood (petrified wood is one process, opal is another). To look for opal: go to the basalt (lava) areas (use a USGS mineral map), then look for depressions (old springs) or flat areas on hillsides where you see the ground pictured in the film. Opals have a specific gravity lighter than sand so pieces (float opal) will come to the surface. Start looking for pieces (the tops will be sun-baked white). If you are finding obsidian (volcanic glass) walk up to a lower temp. mineralization and look for opal. Opal can be black opal, white opal, red (fire) opal, clear opal, or solid opal, and precious opal can be found right along with common opal. Precious opal can (in some cases) be found with ultraviolet light. Some opal can be up to 20% water, and be subject to cracking and crazing if not dried over a period of years. What I personally like about the hillside prospecting method shown is the opal has been thoroughly dried out over the eons and is ready to cut into jewelry from day one. How much opal was recovered in this film? Pounds. Get out there and find yourself some opals -- and defend the 1872 mining law -- it is the only piece of paper that gives the average citizen the right to be on public property, whether prospecting or riding a bicycle. Beware of those trying to change or take it away in the name of "protecting" the land -- they are only taking away your freedoms. Gold and platinum are 15-19 times heavier than other streambed materials and concentrate in low pressure areas and cracks that run across rivers and streams. You look for a crack on the bank, and follow it out until you meet the "gold line" and there you suck it out with your dredge. Gold will be on the outside edge of a river gravel bar, at the head of the bar (large gold but usually beneath big boulders), and at the tail end of a bar (vast concentrations due to river bars forming in the shape of an airfoil and sucking fine gold to the tail end) but be small to microscopic at the tail end. Gold will travel down a river or stream in a line, usually off center of the high pressure water. Gold will settle behind a boulder. A good place to fish, can also be an excellent place to find gold. "Black sand" is iron ore that can be readilly identified in gravel bars and is a ready indicator that gold is probably present. The most effective and economical way for the average person to find paying concentrations of gold in a river or stream is with a simple ($80) sluice that you shovel into and the riffles retain gold, platinum, gems and anything heavy for you. Gold can be found up high on the old river channels and recovered with metal detectors, a gold wheel, a highbanker, or simply by identifying the material, shoveling it in your truck and working it out later in a wheel, or your simple stream sluice. The states which have gold in vast quantities are: Maine, Vermont, Virginia, North Carolina, South Carolina, Georgia, Alabama, Colorado, Wyoming, New Mexico, Nevada, Arizona, California, Idaho, Washington, Montana, and Oregon. The rest have gold as well, some in very good concentrations. All have gems of some kind that a sluice will seperate and hold. Good luck finding the gold of your dreams! Find gold by viewing the other films in this series for all the methods (from simple hand tools to metal detectors) plus even more valuable gems.
