Offer to purchase in 1-28-21-WXH

We received an offer to purchase mineral rights to our interest in 1-28-21-WXH for $5,750. This section has the producing Indultado oil well. We haven’t received any offers for quite some time and was wondering if anyone else had received offers. I could be wrong, but this offer seems quite low. Am I wrong?

21- 06N-04W Perhaps this is the proper way to identify this?

Lots of offers going on in that area. The potential for future wells is why they are offering. The offers will be lower for lower royalty. $5750 is low compared to what I have heard in the area.
