    If you can a picture of the rock opened up would be nice and no need to talk about it. Thank you.

    I found some quartz rocks that picked up on my metal detector as well. Not as obvious as yours, but I think there's gold in it. It was giving off a strong iron target signal. Then I turned the discrimination on and they really went off. I have been trying to figure out a way to easily dissolve the quartz/host rock, leaving just the gold behind. Pretty difficult to figure out exactly how to do it besides smashing and panning them. I have quite a few of them and don't have a rock crusher. I ended up smashing up a fist sized rock with a sledge hammer inside of an ammo can, and it took FOREVER. I know there's a way to dissolve it, but getting the stuff can be difficult. When I fist tried a couple months back, I had read that vinegar would do it, and so would peroxide. I jumped right into it! What I failed to realize, is that it had to be 30% H202 or greater, still unsure of the vinegar. I tried it and it does absolutely nothing. I have heard that caustic soda/lye would get the job done (still unsure of this). Apparently it is a common drain cleaner, but only a couple brands have high percentages in them. Then there's Hydrofluoric acid and let's face it, I wont be able to get my hands on that. There's Hydrochloric acid, but it seems that this is what people are using to CLEAN their gold nuggets/specimens... I'm still trying to gather the right info. Anyways, great rock man. If I were you, i don't think i would smash it with the amount of visible gold. There may be a good little specimen on the inside. Maybe try to see how to dissolve everything but the gold and maybe a leave a little bit of the Quartz on it.

    Will take a lot of acid for a rock this size. If a regular carbide drill will work may a line with it a crack open to reduce the rock in to two or more parts. Be sure to metal detect to help find all the larger values before the next step.

    Looks like the holes helped break up the rock. Thank you very much for posting pictures as this can lift the spirit of Charlie Brown a lot....LOL.
    Don't know if there is some 'Jewelry rock there or not'.

    I don't think there is any jewelry rock, but I'm hoping there is a bit more gold.

    There could be some small areas that are jewelry rock. Maybe the next rock will be better time will tell.

    Man.. I'm sure the easy way to find out what's inside would be to smash...but that's only instant gratification. If you can keep it a specimen (depending on the inside), it could yield some good $$$. Try to find 2 points with gold on the quartz on opposite sides of the rock and test with an ohm meter. This is how you can figure out if it's 1 continuous wire/nugget/specimen. If the first 2 points don't work, find a different couple of spots and test those. Do this until you find 2 points that give you a reading. This way you know that the area being tested is one solid specimen. I would also urge you to get a geology hammer instead of sledges and drills. This will allow you to chip away, and work around any possible good areas so you can maintain it. The stuff that chips off, crush and pan. The stuff that remains in the rock, dissolve in 35% H202. You can dissolve a smaller piece of rock...you just have to get it smaller. There is a really good video series on YT titled "7788.17 grams massive gold and quartz speciman" and you get to watch the transformation into a brilliant specimen. Then there's another video titled "how to calculate the weight of gold in quartz." Maybe check those out and them decide what to do? There could be something very special/valuable in there . Good luck. Can't wait to read more!
