Historic Shirley Bar Claims - MineListings
In the past 3 years gold recovery with a 40 yard per hour plant ranged from .5 oz per hour up to 6 oz per hour. An RMS Ross derocker was purchased in 2013. Now, with both the trommel and derocker running, the washing capacity is about 130 yards per hour. The gold is everywhere on these claims but there are very hot spots.
