Where is your mineral in Young County? Your landman should know whether or not your uncle gave away the leasing rights. If you have the deed it will say on it if he did. Who are you trying to lease with and how much are they willing to give you? If they offer you bonus money then you have the right to lease and the topsoil owner cannot stop them from drilling but some companies don’t want to go to court because it costs money. If the landman is just trying to speculate and sell the lease to someone else he probably doesn’t want to lease it. Ask your landman who the drilling company is. Go on the mineral owner web and search what other people are getting to give it away. Look on the Throckmorton Group if you’re close by Jack, Clay and any county close by. Hope this helps.
