|Location and accuracy||Located about 800 m north of the headwaters of South Currant Creek. Locality 28 of Nelson and others (1985) and locality 30 of MacKevett and Holloway (1977). SW1/4 sec. 12, T. 2 N., R. 25 W., of the Seward Meridian. Locality is accurate to within 750 m.|
Geologic descriptionNo detailed description of the mineralization was found in the literature. Weak mineralization (Resource Associates of Alaska, 1976) associated with the contact between Cretaceous granodiorite and Tertiary granites (Nelson and others, 1983; units Ki9 and Ti12). Unit Ki9 as a medium-grained granodiorite with compositional ranges from silicic granodiorite to mafic tonalite and quartz diorite. Rocks near the margin of the pluton contain lesser quartz and fall within the quartz diorite field. Unit Ti12 is described as coarse-grained biotite granite (North of Currant Creek) and medium- to coarse-grained granodiorite (South of Currant Creek).
