S-3, T-5N, R-7W mineral sale

I own mineral rights in section s3,5n,7w and Ace Energy is wanting to buy them. What is a good asking price and would it be better to keep these? I only own 7 acres in this section. Continental leased them 4 years ago.

Please post in your state and county group for a better response.

Thank you! I’ll look for that group. I’m In Oklahoma and it’s in Grady county
