| Relative position | The Bluff prospect is located on a mountaintop in sections 10 and 11, T. 21 N., R. 20 E., of the Copper River Meridian. It is location 9 of Singer and others (1976), and location 4 of Eberlein and others (1977). The block of claims containing Bluff is adjacent to the west boundary of the Taurus prospect (TC027) block of claims, although the centers of prospecting activity for the two deposits do not adjoin. The geographic coordinates are the approximate center of prospecting activity at Bluff. The location is accurate to within 2 to 3 miles. |
