Cynthia,
It could depend on the location of your minerals in Marion county. Brooks Petroleum has been doing some drilling in Marion county in the last year or so. If you will provide the Section and Abstract # I can see if there is any activity or production in the area of your minerals.
Also you might want to join the Marion County group and present your question to those folks. Go to the main page of Mineral Rights Forum and at the top of the page click on GROUPS and scroll down to your group and join.
