(Somebody's getting royalty money here.)
One aspect of property and mining claim ownership that few (if any) mining and prospecting websites or books ever address is mineral rights royalties. I suspect it's never even crossed the minds of the authors or publishers of these other venues or, alternately, they deem the subject too far off the beaten path from the generic "how to pan for gold" info they dispense. Me? I hope to rectify that situation and increase your mining knowledge at the same time.
