Question on what I have inherited

I inherited: An undivided interest in and to a certain mineral permit, except oil, gas, coal and lignite, in Mineral Survey No. A-215, part Sec. 2, Blk No. 117, Public School Land, Claim “Cude No. 1,” of 20.66 acres, Culberson County, Texas. Can anyone tell me what type of mineral I inherited and where it is in the county. I’d appreciate anyone’s help.
