Royalty rates and bonus consideration in Marion county WV?

I have mineral and landownership of 13.25 acres in the town of Lincoln, Marion county, WV. I have received a Paid Up Oil & Gas Lease offer from XTO-Exxon/Mobil for mineral rights offering 12.5 % royalty and a bonus consideration of $100 per acre. The primary lease term is for 5 years with a 3 year option Can someone advise me on current rates? Also this is a new lease offer and project name is Four States 1H unit.

Thanks,

Richard Knight

Richard, that seems VERY low from my understanding. I've heard of $1,100/ acre in Marion, and that even sounds low. Have you talked to any of your neighbors about their offers?
