| Location and accuracy | Located 4,000 ft east of the head of the easternmost finger of Long Bay, near 1,000 ft elevation. Accurate within 1 mile. Locality 67 of Cobb (1972) and location 55 of MacKevett and Holloway (1977). |
Geologic descriptionCopper lode discovered in 1917. Ore body was reported to be low grade, several feet wide, and approximately 3,000 ft long. Areas of copper sulfide mineralization and other metals are found at many places in the area between Long Bay and Wells Bay. Probably associated with volcanic rocks of Valdez Group (Johnson, 1919). | |

| Mineral deposit model | Submarine volcanogenic massive sulfide? |
| Age of mineralization | Late Cretaceous or younger based on age of bedrock host. |
| Workings or exploration | Some confusion exists about the amount of development of the copper claim(s) located at the head of Long Bay. Berg and Cobb (1967) reported by they are 'undeveloped', however Moffit and Fellows (1950) reported 'considerable work on claims at the head of Wells Bay and on Long Bay.' It is agreed upon that none have produced any ore. |
