I will try to be concise. I know little about rocks, except from high school Earth science. On my property I have found dozens of quartz rocks such as this. Some smaller than my hand, others too big too shift because of their mass and size. The quality varies to chalk white to clear crystals coating much of the surfaces as in this picture I included. We have found twenty plus spots all along one of the ridges on my property. The elevation is 1,200′, we have just searched a relatively small section of the hill, and found quite a bit. I do know quartz is the second most abundant mineral on Earth. Our property is located in Thetford, VT, and encompasses 125 acres on the side of a mountain. I have seen quartz rocks nearly identical to mine for sale of various price. As experts, would it be worthwhile to move these quartz rocks, clean them up, and try to sell them? I realize there is no chance of making large sums of money, but a few thousand potentially is worth my time. I suspect there is more in the ground I’m not seeing. Everything found so far was partially visible walking along the hill with no digging. Thank you for any responses.
