|Location and accuracy||This prospect is at the head of Albion Creek, a short tributary near the head of Ophir Creek. It is about 8.9 miles north-northwest of Council and about 0.3 mile west of the center of section 27, T.5 S., R. 25 W. The location is accurate to within a mile.|
Geologic descriptionIn 2010, Millrock Resources in a joint venture with Kinross Gold Corp. drilled 17 holes less than 120 meters deep on a gold-arsenic soil anomaly in gold and arsenic that extends over a 900 by 2,000 meter area (Millrock Resources, 2010). The anomaly and drilling coincided with what in the headwaters of Albion Creek (BN 103) may be a residual placer over lode mineralization. The drill holes began and ended in calcareous schist of the Precambrian or Paleozoic Nome Group. Two of the holes intersected mineralization. The best intercepts were 15 feet that assayed 1.42 grams of gold per tonne and 30 feet that assayed 2.01 grams of gold per tonne.

|Workings or exploration||Covered by a extensive geochemical survey. In 2010, Millrock Resources in a joint venture with Kinross Gold Corp. drilled 17 holes less than 120 meters deep on a likely residual gold placer that coincides with a strong gold-arsenic geochemical anomaly (Millrock Resources, 2010).|
