Relative position | The Christophosen prospect is on the ridge between the headwaters of Oregon Creek and Penny River; it is at an elevation of 1,620 feet at the ridge crest. Better mineralization occurs on the east slopes of the ridge, and the location shown is the approximate center of an area of zinc-bearing mineralization located within about 500 feet. The Christophosen prospect is on strike with and related to the Aurora prospect (NM140). This location is about 1.25 miles west-southwest of the location given by Cobb (locality 10; 1972 [MF 463], 1978 [OFR78-93]). |
