|Visible gold in core sample of granodiorite from the Copper King mine, Wyoming. Many people like|
to make gold out of pyrite, chalcopyrite, or mica. If you learn about the physical characteristics of
minerals, you have a better chance of finding gold deposits. For instance, mica is often mistaken
for gold in black-sand concentrates in a gold pan. Why? They really have no characteristics in
common. Gold is very heavy (specific gravity = 19.3) compared to mica (sg=2.8 to 3). So, when
panning, mica will be difficult to wash out of a pan, not because of its specific gravity, but because
of crystal habit (essentially a two-dimensional flat crystal that will slice through water and it
rolls). Gold will just sit there because of its specific gravity.
As a research and consulting geologist, I came across dozens of mineralized properties - many were just waiting for someone to prospect and find them. So, I decided to pass this information on to you. But why should I care about you since we've probably never met, and why wouldn't I just try to hoard everything?
