Mineral rights Leasing question

I have a company wanting to lease some mineral rights that I own in Utah. It is 3.9 mineral acres. How do I determin if the bonus amount and royalty’s is a fair amount. What they offered is not much for the bonus amount but the royalties seem good comparatable to what I have been able to research online.

The bonus amount is entirely negotiable. get all they will agree to give. There is no fair amount. The practice of keeping you in the dark about drilling activity is practiced to keep you ignorant about what is “fair” value. Try to research the drilling activity in your area before you agree to a lease.
