Prospect could not be located 1972-73. Site is in Misty Fiords National Monument.
Location: The Chickamin prospect is in Section 9 at an elevation of about 3000 feet on a precipitous west-facing mountainside overlooking Chickamin Glacier. It is about 1.4 mile north-northeast of Disappearing Lake (Berg and others, 1977, p. 84; Elliott and Koch, 1981, p. 11, loc. 27).
Geology: The country rocks in the area of the Chickamin prospect are metamorphosed pelitic strata of the Jurassic or older Mesozoic Hazelton Group that are underlain and locally intruded by the Triassic Texas Creek Granodiorite. Both the Hazelton and Texas Creek, in turn, are intruded by the Eocene Hyder Quartz Monzonite (Smith, 1977; Berg and others, 1977, p. 15-18, 22-23). Buddington (1929, p. 100) describes the deposit as a quartz stringer lode and a three-foot-thick quartz fissure vein in graywacke. The stringers and vein contain galena, chalcopyrite, sphalerite, pyrite, and a little pyrrhotite and tetrahedrite. In 1972-73, a U. S. Bureau of Mines field team searched for but could not find the prospect, which probably was covered by snow (Berg and others, 1977, p. 84). A grab sample from a foot-thick granitic dike in the area near the prospect contained traces of pyrrhotite and goethite.
