Location and accuracy | The Phoenix prospect is on Hyphen Gulch, a small tributary of Iron Creek, at about an elevation of about 3,600 feet. The prospect is near the center of sec. 22, T. 26 N., R. 2 E., Seward Meridian The location is accurate to within 1/4 mile. This is locality 72 of Csejtey and Miller (1978). |
Geologic descriptionThe Phoenix prospect is in copper-stained basalt which is locally replaced by chalcopyrite, specular hematite, minor bornite, and quartz. Hematite and minor amounts of the sulfides also occurs in several narrow veins (Capps, 1919 [B 692]; Schmidt and others, 2002). A small shear zone, 2 to 3 inches wide, trends northeasterly, dips to the northwest, and contains minor quartz and copper staining (Capps, 1919 [B 692]). A 0.6-foot chip sample collected by the U.S. Bureau of Mines contains 900 parts per million copper (Fechner, 1986). Mineralization is exposed in a surface cut. | |
