|Location and accuracy||The Ekakevik occurrence is in a series of low ridges about 2.6 miles north-northeast of the highest peak of Ekakevik Mountain; it is near the center of section 36, T. 9 S, R. 22 W.|
Geologic descriptionThe Ekakevik occurrence consist of barite and minor witherite, interbedded with Mississippian Lisburne Group chert, shale, and limestone (Kelly and others, 1993, Kurtak and others, 1995). Bedding is not exposed but the barite is estimated to be about 20 meters thick and can be traced for about 165 meters along strike. The deposit has an indicated resource of 2,275,000 metric tons of barite with a specific gravity of 3.9.
