We have minerals in T157N; R103W; Sections 29 and 31 so we are fairly close to you. As far as the bonus/acre, we leased ours in 2008 when prices were low so I couldn't help you there. Your best bets are to talk to someone who has recently leased in the area or go to the North Dakota Industrial Commission website , click on "Related Links" and click on "State Government"(North Dakota State Land Dept.), click on "Minerals Mgt. Div." then go to monthly sales by county. This will give you an idea of what bonus amounts are bringing at public sales. When our lease expires, I'm going for 20% royalty, and a 3 year lease with many new stipulations in the lease that currently is not in place. You might refer to past posts on this website to get an idea contents of lease. Just remember, they are you're minerals and you set your own prices and terms. If they are not interested then SHOP AROUND!!
