Bonus on only horizons below 11,300 ft in Reeves Co

So we potentially have a company interested in leasing horizons which are not presently under lease on a property they purchased from another company. What bonus range is to be anticipated? The Blk is 54,T7S. What is the going royalty offer?

I’m very sorry - misread the location. We are in Block 55, so my post was of no help!
