    It is definitely getting a lot tougher now haha. We did pretty darn good last weekend though in a spot that we have hammered. Just had to go slow and get up under the bushes. Ill post up our finds later today. 

    Are still hunting at you know where or some other place?

    If you want $2k for a bucket of rocks you are going to have to at least give it a try.

    You might get a range. Variations with the specific gravity of quartz on  large pieces like that is the issue as I see it.

    I think he'd be better off if he were to get rid of that excess quartz by knocking it off and acid treating the remaining pieces so you'll have some nice gold in quartz specimens. There's just too much quartz attached as it is.

    It looks like 20 kg. of quartz to me.

    You calculate the amount of gold in quartz with a specific gravity test. Take one of those specimens and do an SG. That will give a prospective buyer an idea of how much gold might be in the rock. 

     

     

    In order to get the desired results, everything has to be EXTREMELY precise. With such  large specimens and the small amount of gold, it may not be possible.. :m2c:

    1 in 5 electric vehicle owners in California switched back to gas because charging their cars is a hassle, new research shows

    In roughly three minutes, you can fill the gas tank of a Ford Mustang and have enough range to go about 300 miles with its V8 engine.

    But for the electric Mustang Mach-E, an hour plugged into a household outlet gave Bloomberg automotive analyst Kevin Tynan just three miles of range.

    Won't make any difference. Gas operated vehicles will become extinct in the coming years and the technology will get better as well.

    I meant to post earlier, this is a beautiful specimen! What general location did you find it?  It’s interesting how the calcite intruded into and filled the void inside the chalcedony.

    bunch of this material hit the market about 10 years ago but I haven’t seen anything new since. One dealer was giving the location as Oglala National Grasslands, Sioux County Nebraska and another dealer was giving the location as Scenic, Pennington County, South Dakota. This piece was labeled as the latter.

  6. I really think every gold prospector should have a good battery powered SW lamp in their arsenal. You run into all kinds of outcroppings, ore dumps, etc that can be checked out for fluorescence.

    Good multi colored specimens can fetch hundreds of dollars on the market depending on number of colors, patterns, aesthetics. All it takes is one good specimen to pay itself off. A really good lamp can be used during the day as well.

    The green in chalcedony under short wave UV, found in western Wyoming, is from Uranium. I've found quite a bit of it in the Green River Basin.

    All fluorescent minerals contain minor  "activator" elements such as uranium, lead, manganese, chromium and others.

    Try it under a short wave mineral light, the chalcedony I’ve collected glows bright green.

    Sometimes you find calcite sandwiched between two layers of chalcedony but only in certain locations. This is called watermelon chalcedony for obvious reasons.
