The Joker group of 20 claims were staked in 1952. No claim monuments or evidence of workings were found by the U.S. Bureau of Mines in 1973. This site is in Misty Fiords National Monument.
Location: The Joker group of 20 claims is at an average elevation of about 1600 feet near the foot of the ridge north of the Leduc River and west of Clara Smith Glacier gorge (Berg and others, 1977, p. 73, 123, and plate 1). The site is about 0.6 of a mile west-southwest of the Alaska-British Columbia boundary. The location is accurate to within about a quarter of a mile.
Geology: The country rocks in the general area of the claims are metavolcanic and metasedimentary strata of the Jurassic or older Mesozoic Hazelton Group, and Eocene quartz monzonite and granodiorite stocks that intrude the Hazelton (Berg and others, 1977, p. 15-26, and plate 1). A field investigation in 1973 by the U.S. Bureau of Mines (Berg and others, p. 42, 123) reported very sparse pyrite and possible moybdenite in quartz-calcite fissure veinlets in Hazelton schist and gneiss that is intruded by aplitic quartz monzonite dikes.
Alteration: Intense iron oxide alteration of country rocks within 6 inches of the aplitic dikes.
