Location and accuracy | This prospect is north of Dream Creek, about 2.5 miles east of Gibraltar Lake. It is at an elevation of about 500 feet in the NE1/4 sec. 5, T. 10 S., R. 31 W., Seward Meridian. The site, which is locality 28 of MacKevett and Holloway (1977), is accurate within about 1 mile. |
Geologic descriptionThis prospect appears to be in a batholith of Jurassic, medium- to coarse-grained, quartz diorite and subordinate diorite and granodiorite, containing roof pendants of metamorphic rocks (Detterman and Reed, 1980). Tertiary basalt and andesite is exposed west of the prospect. Lode claims, probably for iron, were staked at this site (U.S. Bureau of Mines, 1973; MacKevett and Holloway, 1977). The deposit probably consists of disseminations and veinlets of magnetite in relatively mafic phases of the batholith. | |
