|Location and accuracy||This prospect is at an elevation of about 3,900 feet on the north slope of Gold Hill, between Lucky Gulch and White Creek. The site is in sec. 12, T. 20 S., R. 2 E., of the Fairbanks Meridian. This location is accurate to within 1,000 feet.|
Geologic descriptionThe country rock at this prospect is micaceous schist of unknown age. Foliation strikes 58 SE and dips 18N. The deposit is a 4-foot-wide shear zone consisting, from the top down, of a one-foot-wide quartz vein, with three feet of schist cut by small quartz seams, and quartz stringers. Most of the quartz is sugary and contains vugs lined with terminated crystals. Good values of gold were panned from the weathered material, but there was some indication that in the unweathered material, the gold was in the sulfides, rather than free-milling (Tuck, 1936).
|Geologic map unit||(-147.290259242903, 63.196553193884)|
|Mineral deposit model||Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)|
|Mineral deposit model number||36a|
|Alteration of deposit||There is a color anomaly associated with the prospect due to weathering of pyrite.|
|Workings or exploration||Surface trenches and cuts, one short tunnel and one 60-foot tunnel that missed the lode.|
|Indication of production||None|
Additional commentsShear zones in this area having shallow northward dips are part of a thrust zone best exposed underground at the Denali Copper prospect (HE191).
