Geologic setting

Geologic description

The 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.
