    Our first encounter with a prospectus map for an area south of Rollinsville up in Gilpin county. The OPA Mining Co. (which based off the "Names of Claims: Oak, Pine Ash") and is offered at "One Cent Per Share". Situated on Perigo mountain it shows the other nearby claims as well as the grid of the small town of Rollinsville.

    Condition is very good, and comes with single fold description of the prospect. Image size is approximately 18.5 x 14 (inches)
