As an example, last week I purchased a total of 10 gms of gold nuggets. Each nugget will usually contain 95% or higher amounts of gold with
minor traces of impurities such as quartz grains. Sure beats trying to find them yourself and dig them out of the ground the hard way !
Here's 2 of them:
Depending on the gold mining district the gold come from the gold could have anywhere from 50% to 90%.gold,
the Fineness of gold in any mining district is usually between 2 to 10 points higher then the hard rock ores in that district.
by the way any gold under 50% is many times called silver or copper nuggets or native copper or silver.
if you find quartz grains in nuggets that is a sign they are not water worked and there is still a lot of silver in them.
these nuggets will be within a point or two of the fineness of the district.
when i fire assay Calif gold nuggets or gold ores i can tell within 10 miles of where the gold came from and in some cases the name of the mine by the
percentage of the gold silver and copper in the gold.
the federal government used spectroscopy testing back in the 1930s at the mints to tell what mine gold came from to prevent highgrading of gold from
if you tried to sell gold from a mine that had been highgraded you would be arrested.
Mine promoters still get arrested for taking money from investors by showing gold samples from another mine and claiming it from there mine
I was at a mining equipment show one time and had some one show me high grade gold he claimed from his mine in the calif desert.
I knew where the gold can from just by looking at it and i told him it was from the sixteen to one mine in Alleghany Calif he all of a sudden had he
needed to go and left.
