The Illinois Basin has been my exploration playground for 44 years. Petroleum exploration remains my primary focus. However, I have lately focused on the abundant coal and fluorspar resources in Southern Illinois and have some great opportunites available for sale. Come visit my booth (4529) to discuss Illinois Basin oil prospects, coal, and fluorspar. Flurorspar is a USGS critical mineral and the renewed mining of this resources has garnered much interes over the past couple of years.
