My sister and I received a letter Thursday regarding leasing mineral rights that will be available shortly oink Carter County 4-03S-03W. It has been leased twice but nothing has happened. This new company is offering Option 1: Bonus $1250 3/16% royalty for 3 yrs; Option 2 Bonus $1000 1/5% royalty 3 yrs or Bonus 3 $750 per mineral ac 22% royalty. I have never been offered 22%. Is this because they want to just hold this lease but probably won’t drill?
