This property is in Township 11 S., Range 6 E., Section 25, SW ¼, SE ¼, SW ¼, near the town of Herod.

The Williams Prospect was a small residual deposit with a 75 foot shaft, with minor fluorspar.

Weller et al. (1952) reported another "Williams Prospect" in their table, but that deposit was located in Hardin County and should not be confused with this prospect.
