Relative position | The Aurora prospect is in the headwaters of Aurora Creek, an eastern tributary to upper Cripple River. The mineralization trends north-northwest in a zone that extends for more than 2 miles to a related deposit about 1 mile south of the Aurora prospect called the Christophosen (NM141). The location of the Aurora prospect is at the intersection of the mineralized trend with Aurora Creek; it is at an elevation of 700 feet. This location is the approximate discovery point; it is accurate within about 500 feet. This is locality 69 of Cobb (1972 [MF 463], 1978 [OFR 78-93]). |
