Pure Gold Question
- Thread starter billbeep
- Start date
Where would pure 24K nuggets read on my CZ3D in Salt Mod? This is the Black hills area.Heck I live in coal nugget country but once read tape two Jefferson nickles together will simulate an average nuggett..Whether this is true don't have a prayer but would beg borrow or rent a gold nugget unit if this is just for one trip as thats what they are made for..I would imagine like everything else size would have quite a bearing and perhaps an avid gold nugget hunter can chime in to give some expert advise...
Hey there BillBeep,
Not knowing your machine I can say the nuggets may not be bigger than a rice crispy. Let's say that is a big one. Lead sinkers are good practice for the yard to simulate small gold. They may read into Iron and higher toward a nickle ID. A Nickle has the characteristics of a 1/4 oz nugget at 5 grams weight especially in ID. That is a large nugget in most parts of the world. A one ounce nugget has been said to be more rare than a five Karat diamond. Imagine how many more smaller nuggets populate the landscape near a 1 oz nugget?
Small nuggets and a small coil.
At distance some small nuggets may act like an iron target, but jumpy and indeterminate in ID. Black Hills gold is different colors from different alloy's if I am correct. The more it looks like copper, well the more copper it is. Native nuggets are rarely 999 fine gold, so some are 600+, 700+, 800+ and 900+ fine depending on the natural alloy. Many natural alloys include other metals like silver, copper and platinum group metals (PGM's). Ask the local jewelers or someone who knows about the native gold there, and it's composition to learn more.
If you are going panning some machines can give an iron or ferrous reading. This would tell you about black sand streaks. These streaks would also be good producers in gold country as the black sands are close to the specific gravity of gold and where one is, the other is associated.
Good Targets.
Many times the challenge is the trash or junk iron in the old tailings or streams and that is where an iffy signal needs attention. Take a strong magnet with you to help sort out the trash. I would use the least amount of iron discrimination needed to hit a half split-shot.
Sorry I am not familiar with your machine but hopefully you will have a better idea for the targets you seek. The big ones will take care of themselves.
Good luck
Sunny Jim

Sunnyjim has made a knowledgeable presentation.
Black hill NOT pure gold. 10% or more copper gives it that pretty rosey color.
For a test sample try some birdshot... open crimp end of a shotgun shell with yer buck knife for a few bits of shot.
maybe 2, 3, and 4 bits of birdshot in a folded over piece of scotch tape should be good test.
Lead birdshot, that is... or cut off some bits of lead solder... small split shot sinkers good too.
Nickels! LoL That would be a GREAT place! Plenty of partners lining up!

All in all depends on the size of the nuggets 
would imagine in most cases BB shot is more like it and two nickles taped together would produce if a gold nugget a real nice find..Thanks for your knowlegable info as again all we have in Pa. is coal nuggetts and some glacier gold found in trout creeks that would take many to make a BB size nugget and doubt if any metal detector would pick them up...
