I'm in an area not known for much gold. But quartz is more than plentiful. I've seen veins in bedrock close to 2 feet wide. Without seeing visible gold in the veins, what would be the "smoking gun" signal that justifies me bringing home a couple buckets to crush up and pan? If I were to chip out some should I take it out of the center of the vein or where it meets the rock? Or does it not matter? Looking for a lesson on quartz basically. Thanks.

I have alot of quartz on my claim and the old timers called it pocket quartz. I usually take the pieces and run my MD 20 over it and if nothing hits i toss it. For me i don't like to waste to much time on it when i could be processing materal. But some times when i do get a bucket full i'll spend the time and crush it like Astro.
I just looked at the GPAA paperwork. It says they will crush the ore to a powder and pan it out and tell you the results. Lol...I can do that. It also says maximum sample can be no larger than a flat rate box. Isn't there multiple size flat rate boxes? I assume they mean the largest box? I may have to call and ask some questions. I need to renew anyways.
If you are a GPAA member you get now I think 3 free assay a year.
wow That sounds Great Durant. Do you Know if it's a Complete Mineral Fire Assay, or just Gold and Silver. ether way it is a Great Deal and You Get a Free Pan.
The Only way to know 100% is to have an Assay this is the cheapest assay co I know of good luck http://www.assayfast.com/
I like the little crusher in the first vid. I'm gonna make something similar. Most of the pieces I looked at are just solid white but I found a few with tiny black specks and some with flat silver specks. Looks like mica. I broke some open and found a couple that were stained different colors but not many. I took a vid and pics of some of the quartz. Does any of it look worthwhile to you?
Here is a couple pics of the stained rock. A yellow one...
And this one was red.
In this one you can barely see the silver specks I think are mica.
And lastly...I just thought this one with veins going in both directions like tic-tac-toe was cool.
I been thinking I should get a md or garret pointer but cant justify spending the cash right now. I guess the only way to know for sure will be bringing some home and crushing it. Just want to make sure I'm bringing home the best samples I can.
Mineralization is the main thing. Visible sulfides like pyrite or chalcopyrite are a big plus. Also red staining in the quartz or a gossan stain from oxidizing minerals.Keep in mind that most sulfide gold is small and you can have refractory ore which will not have gold visible (google refractory ore for good explanation of it).
Here's a link to my video on crushing quartz to find gold, has some great examples:

There's five parts of that series I made so check them all out. I show some high grade quartz copper ore in there (fifth video) towards the end that had nice gold.
Any other questions feel free to ask.
