The prospect is in the Chuck River Wilderness Area which is closed to mineral exploration and mining.
Location: The Croney the adit is about 0.1 mile south of peak 2770 or about 2 miles south of the abandoned town of Sumdum at the head of Sanford Cove. The adit is about 0.6 mile south-southeast of the center of section 2, T. 49 S., R. 74 E.
Geology: The Croney claim, which adjoins the Sumdum Chief Mine (SD028) was patented in 1900 and consists of an open cut and a 27-foot adit (Kimble and others, 1984). The deposit consists of a stringer zone of quartz that strikes N83E and dips 78N. The zone is parallel to the bedding of the host rock, which is Cretaceous graphitic limestone (Brew and Grybeck, 1984). Several samples were devoid of substantial metal values but all contained 1 to 3 parts per million silver.
Workings: The only workings are a trench and a 27-foot adit.
Age: Cretaceous or younger based on the age of the host rock.
