Prospecting is about looking for gold in new places. Hence the word Prospector!
Wyoming has been virtually ignored for the wealth it contains. Most think of it as a cattle state and a vast barren wasteland of nothingness...witch most of it is, But.
There are many areas I have found in Co and Wy where there is gold where "its not supposed to be"
Keep in mind only about 20% of Wyoming's mineral deposits have been explored, New stuff is found all the time, Just in the last 30 years have been Diamonds and a new gold district, in the last 8 have been Iolite, Ruby/sapphire, peridot, new uranium deposits, Just in last 3 years has been opal, more gold deposits, including one area where a guy with a metal detector managed to pull out over 400 nuggets in a copper district!!! The place is also known for jade, coal, oil iron Tungstun, I can go on and on and on.
So, word of advice on Wyoming. Gold is where you find it, as well as a lot of other weird things and where that may be...who knows until you prospect and look.
Basically, Wyoming is filled with Billions of Dollars in Mineral wealth. And in a stat with fewer people per square mile than Alaska, There are good chances of finding things.
I venture up there all the time to look for fun and new things, And I find em!
