Ronald - I believe that is on the low side from what others have posted. That is a very hot area of Blaine County and, honestly, one of the hottest areas in the nation right now. If you look through the Blaine discussions I think you'll see some of the other offers.
Without knowing the details of the lease holding your minerals, like the royalty percentage, it could possibly be a very good offer. However, if the lease has a 25% royalty and pugh clauses, it is a low offer. When selling minerals you need to convert your mineral rights to royalty acres. Feel free to message me with questions, or combining your minerals with others to get a better price.
