I've worked with many mine owners, mostly those in Nevada. Almost all the mines are seasonal (yes ores ripen at different times of year). During the times they are closed they will be visited by claim jumpers. Yes the west has not changed much. I've seen people post up killer pieces on Facebook and the owners of the mine go ballistic because it's theirs and nobody does anything about it. It's almost like hahaha look what I got while you were gone. It's really a strange business world.
