A small northeast-trending shallow mine near Cave-in-Rock with a shaft that was between 15 and 60 feet. The mine was located in T. 12 S., R. 9 E., Section 13, SE1/4, NW1/4, SE1/4. The operator of the mine in 1940 was the Cache Mining Company (Weller et al., 1952)
Weller et al. (1952) reported that this property, along with the Frayser and Winn properties were small, narrow replacement ore bodies that were mined at three levels within a vertical zone of about 30 feet in the basal part of the Fredonia limestone. Besides bedding replacement fluorspar, a small 3 foot vein was also encountered here. Production here was at a small scale. "Gravel spar" was also encountered as well.
Weller et al. (1952) noted that the Winn, Underwood, Rogers and Frazer properties lie outside of the principal mineralized belt of the Cave-in-Rock District.
