I talked to a high ranking employee of Camp Minden a few months ago, he said the mineral rights belong to the federal government. I think Camp Minden is approx. 9 miles by 3 miles, that would make a nice lease bonus check lol.
Snake, if I remember correctley the people that sold to the government back in the 40's kept the rights. I may be wrong it was back in the late 90's when I ran title for a cell tower on the property.
