Located 23 miles south of Libby, the land surrounding the Libby Creek area has been of interest to prospectors since the early 1860s, when it was home to up to 600 miners working at a camp known as Libbysville.

An example of some of this extraordinary ore was a lot of about four tons from the Florence mine during the last days of a lease that averaged over 300 ounces of gold per ton.

For simplicity, I will assume that you wish to make enough profit so that you can comfortably pay your bills using just the profits from the mine.
