Detecting gold in rocks

[liquid1]

Pappy is it possible to detect gold if I am shooting right on top of rock, quarts with vanes
or creek beds..I will be using the fisher F75 it likes gold/silver and jewlry ..But I dont know if the rock will shield it..My uncle taught he found a chunk heavy rock but I couldn't get a reading with the rock laid out on the ground at any angle..he didn't want to bust the rock
with a hammer..he is old school and has found gold in the past..any info..thanks james

if any gold is in the rock ,that machine should pick it up if you dont have gold and foil notched out..some times i use pin point to see scan with....creek

Thanks creekrat..thats what I was thinking..i was on 0 discrim 99 sense and in JE and DE mode no notch, and pulled the trigger ..I walked all over the rock just hoping for a signal..I got no beeps...

But I would think that if there is any gold or metal on a rock that rock will beep and if I were you and it beeps I would take it somewhere private and break it down and see where the metal is. Now that I think about it one time I was in key west and a rock did beep on me and I kind of ignored it. I might have missed something now that I think of it. I will never let that happen again.

It should detect the gold in the quartz. Is he keeping the rock just because it is pretty, collection or what? If it were me, I would crush the rock and pan out the gold and then get it tested.

Good idea pappy, theres quite a bit of it where this was located..theres even a hillside with the quarts pokeing out..I plan on getting back out there and doing some major hunting in the creek this rock came from and the hills..its on about 2,000 acres..and the owner of the land is pretty sure he has some gold he wants looked at...I will call uncle in the morning..asap..thanks pappy and folks..james
