Recently received an offer to purchase mineral interests in section 14-7N-5W for $5000 / ac at 1/8 royalty interest and another (from the same group) in section 14-5N-5W for $3500 / ac also at 1/8 RI. Kaiser Francis operates in both. The only thing I can think of that would account for the difference is expectations for current or future drilling and production activity.
