Lease or sell mineral rights

We live in Michigan and just received a letter from Pinnacle land Services in regards to almost 2 acres my wifes mother (She passed away this past Sept. and my wife inheired everything in her will) has in Union District Richie County WV. Pinnacle wants to purchase the property, we are new to this so any feedback on what is happening with the drilling in Richie County would be much appreciated. Thanks.
