| Location and accuracy | The prospect is near the forks on the south side of the canyon of Christian Creek at an elevation of about 500 feet. Christian Creek is an east tributary to upper Nome River. It is locality 33 of Hummel (1962 [MF 248]), and locality 41 of Hummel (1975) and included in locality 31 of Cobb (1972 [MF 463], 1978 [OFR 78-93]). The prospect is located within about 1,000 feet of the coordinates. |
Geologic descriptionThe prospect is a copper-bearing mineral occurrence contained within calcareous metasedimentary rocks (Hummel, 1962 [MF 248]). It appears to be on the north or hanging wall side of the same fault structure that is adjacent to a nearby scheelite prospect (NM075). The prospect belongs to the same class of stratabound copper deposits as those at Copper Creek (NM053) and Copper Mountain (NM054) identified by Hummel (1975) as occurrences or prospects in silicified marble, that contain visible sulfide or other ore minerals. | |
