Sell or not to sell mineral rights

I received a letter from Mayhawk energy in Norman wanting to buy my mineral rights, section 9,4 N, 8W. in the past, I was told thru this forum nothing is going on there. had a 3 yr lease that expired in 2017. thanks

What exactly are you asking?

guess I would like someone to look in their crystal ball to see if there may be some activity. why do they want to buy my rights if nothing is happening \thanks
