Mineral rights value and oil lease terms in fergus county

I AM A NEWBE AT THIS AND TRIED TO SEND THIS BEFORE SO THIS MAY BE A REPEAT.

I HAVE BEEN OFFERD A LEASE FOR MINERAL RIGHTS IN FERGUS COUNTY. SINCE I AM NOT IN THE BUSINESS OR THE AREA I HAVE NO IDEA IF THIS IS A REASONABLE OFFER OR NOT.

THE KEY ITEMS OF THE LEASE ARE AN OFFER OF $5.00 PER ACRE FOR THE FIRST 5 YEARS AND AN OPTION AT $10.00 PER ACRE FOR AN ADDITIONAL 5 YEARS. THE ROYALTY OFFERED IS 1/8 OR 12.5%

I BELIEVE THERE IS NO CURRENT ACTIVITY IN THE AREA AND THAT THIS IS AN ATEEMPT TO ASSEMBLE A PACKAGE OF LEASES THAT WILL ATTRACT SOME DRILLER TO COME IN AND DRILL.

ANY INFORMED REPLY WOULD BE WELCOME
