Township 12 South

I have a currently lease on Township 12 South, Range 38 East, N.M.P.M. Section 26: SW/4 & W/2SE/4 that is soon to expire.
7.50 net mineral acres

  1. I am wondering what would be new current value of the area since it has been 3 years.

More importantly, I had inherited this land and was unaware of it till I was contacted and its from 30 years ago, how would I go about seeing if, which I believe I do, I had other mineral rights in Lea county as well as other south eastern NM. I can not get ahold of the original will of my grandparents at this time.

I am a total rookie to this and could use all the guidance I can get. Thank you and hope you all have a safe and Blessed Thanksgiving.
