Hi Dan. If you go on the ND website http://www.land.nd.gov/minerals/oilandgasleasing.aspx to see what public land leases in your area went for. My experience is that the public leases will often go for 30-40% more than a private lease would but they would typically do a 1/6 royalty. Whereas sometimes a private lease might fetch a 20% royalty. Good luck!
