Research into selling mineral rights - Montana

This is an updated re post from several years ago. We are now researching selling the mineral rights but I was wondering if there was any current information about this area

We have 150 acres of mineral rights in Richland County at t24n r56e sec 6.

The last lease we had with Continental Oil expired more than 10 years ago. At that time a permit to drill had been approved and a double pad had been laid and then the permit was allowed to expire, our lease expired and that was it.

I am wondering if anyone has any current knowledge about activity in this area.

Thank you

Philip Rachford
