|Location and accuracy||McArthur Creek is just west of Moosehorn Ridge. The creek runs approximately north-south for more than 20 miles, and has numerous placer mine claims on it. The coordinates are arbitrarily placed at the headwaters of the creek in section 31, T. 15 N., R. 23 E., of the Copper River Meridian. The location is known to about 10 miles.|
Geologic descriptionMany placer claims exist on McArthur Creek, and there probably are productive placer mining operations in this area. There is a large amount of placer mining activity in this area on the Canadian side of the border (Foster and others, 1976). Claim names in this area include Boundary, Border, and Alien. The regional geology consists of Paleozoic gneiss and schist (Foster, 1970).

|Age of mineralization||Quaternary?|
|Workings or exploration||There are many placer claims along McArthur Creek and a long history of mining along the creek but details are lacking. On the Canadian side of the border, there are many placer gold mines with historic gold production on McArthur Creek.|
|Indication of production||Undetermined|
|Production notes||Some placer gold recovered.|
