Comments
Comment (Deposit): Other Comments = A rocker set up in a gulch 300 to 400 feet above Accident lode was reported to have obtained good gold values from stream gravel.
Comment (Geology): Geologic Description = The Accident prospect explores one of several mineral deposits in a belt south of Valdez Creek. The Valdez Creek area is underlain by pre-Upper Triassic pelitic clastic rocks, minor tuff, limestone lenses, and conglomerate. The rocks apparently vary abruptly in regional metamorphosed grade, from prehnite-pumpellyite through greenschist and amphibolite, to granulite. These rocks are intruded by Upper Jurassic alkali gabbro and by dioritic intrusions of Late Cretaceous and Early Tertiary age (Smith, 1981).? the bedding and foliation of the strata strike about N 75 E and dip steeply northwest. Strike-slip faults having a similar orientation are also present, particularly on the south side of Valdez Creek (Smith, 1981). On the north side of the creek, a northwest-dipping thrust fault in part explains an apparent 'telescoping' of the metamorphic rocks.? the Accident occurrence consists of a quartz vein on the same lode system(?) as the Yellowhorn prospect (HE208). Decomposed slates are intruded by siliceous, fine-grained leucocratic rock containing abundant pyrite. The gold vein contains galena and sphalerite.
