Location and accuracy | This occurrence is located in the NE1/4 section 15, T. 9 N., R. 1 E., of the Seward Meridian. It is at an elevation of 1,500 feet on Slate Creek. This is location 18 of Cobb and Richter (1972), location 13 of MacKevett and Holloway (1977), location 5 of Cobb and Tysdal (1980), and location S-313 of Jansons and others (1984). The location is accurate to within a quarter of a mile. |
Geologic descriptionThe occurrence consists of two small fault-controlled quartz veins in sandstone of the Valdez Group of Late Cretaceous age (Tysdal, 1978 [MF-880-A]). One fault strikes N70E and dips 70SE; the other fault strikes N50E and dips 10-15E (Moffit, 1905). The veins carry arsenopyrite, chalcopyrite, galena, pyrite, sphalerite, and free gold (Jansons and others, 1984). This deposit may be an extension of the veins at the Slate Creek No. 2 (SR040) and the Kenai Lu mine (SR035). All three veins are fault controlled and are nearly on strike (Martin and others, 1915). | |

Additional commentsThis deposit may be an extension of the veins at the Slate Creek No. 2 (SR040) and the Kenai Lu mine (SR035). All three veins are fault controlled and are nearly on strike (Martin and others, 1915). |
