If you start getting letters from companies that purchase mineral rights, that will be a good sign that you have something of value. They send letters offering to purchase your rights for a certain amount. They are lowballing the value of those minerals. Also, they send out those letters when they believe that the price of oil is about to rise so that they can cash in on the uptick.
My grandfather told me once “Never, ever sell your mineral rights”.
Thank you...and we will follow your grandfather’s words.
