|Location and accuracy||This occurrence is located at an elevation of 2,000 feet (610 m) in an unnamed creek basin in Section 33, R. 23 S., R. 24 E., of the Kateel River Meridian. Location is known to within 300 feet (91 m).|
Geologic descriptionThe Katy-O occurrence is a poorly exposed gossan in a small area of unit 'Dlr' of Andrews and Rishel (1982); it is probably equivalent to the lower Whirlwind Creek Formation of Dutro and Patton (1982). Host unit is inferred to be Lower Devonian, based on fossils. The age of the mineralization is unknown. Gossan in float contains 1 percent zinc (Andrews and Rishel, 1982).
