| Relative position | The mine, on the northwesternmost part of Chichagof Island, is on a northwest-facing mountain side below Vein Mountain and east of Column Point. Workings have been reported at 850, 980, and 1080-foot elevations (Reed, 1938). The location is near number 63 of Cobb (1972). Another mineral locality probably exists on the mountain at an elevation of about 1500 feet. The approximate location of the mine is shown on Plate 16 of Rossman (1959, B 1058-E). The coordinates of the site are approximate, but are probably within 0.25 mile of the reported mine workings. |

| Deposit | Model Name = Low-sulfide gold-quartz vein (Cox and Singer, 1986; model 36a). |
| Deposit | Other Comments = the Vein Mountain area was proposed by Rossman (1959, B 1058-E) to be part of a gold-favorable metamorphic belt that extends from the Chichagof mines north-northwest through the Apex-El Nido area to Vein Mountain. Rossman proposes a very favorable gold prospecting area exists that is centered near the southwest ridge of Vein Mountain (about 58.11 and 136.42). The beach adjacent to the creek draining the mineralized area (location about 58.122, 137.424) is reported to be auriferous. The area appears to be on U.S. Forest Land available under the Mining Law. It is outside of Glacier Bay National Park and Preserve. |
