Location: The Oregon and Washington prospects are east of central Kitkun Bay at an elevation of about 200 feet. They are about 0.9 mile north-northwest of hill 1328 and about 0.6 mile northeast of the center of section 28, T. 77 S., R. 88 E. The Hula Hula prospect of Bufvers (1967) may be the Washington or Oregon prospect or the Kid prospect (CR180).
Geology: These old prospects, which have been variously named, were discovered in 1900, but are only mentioned in passing after 1908 (Brooks, 1902; Wright and Wright, 1908). The host rocks are chlorite schist and marble of the Wales Group of Late Proterozoic and Cambrian age (Eberlein and others, 1983; Brew, 1996). Brooks (1902) described the Oregon prospect as a pyrite-bearing quartz vein at the contact of chlorite schist in the hanging wall and and marble in the footwall. A sample assayed $4.80 (probably in gold at $20.67 per ounce). Wright and Wright (1908) described the Oregon prospect/claim as a 3-foot quartz vein that crosscuts chlorite schist and contains pyrite, chalcopyrite, sphalerite, and minor values in gold and silver. They describe the Washington prospect as a 10-foot band of brecciated limestone and schist that strikes N45E. The limestone is cut by quartz stringers and veinlets with minor sulfides. The only workings are several open cuts and there is no record of production.
Workings: The only workings are open cuts dug before 1908.
Age: The veins are younger than the Late Proterozoic or Cambrian host rock.
