Site is in Lake Clark National Park and Preserve.
Location: In a divide between the Telaquana River drainage and the Neacola River drainage, about 11.2 km E-SE from the mouth of Telaquana River. This is locality 4 of Nelson and others (1985) and locality 18 of Mackevett and Holloway (1977). NE1/4SE1/4 sec. 25, T. 10 N., R. 24 W., of the Seward Meridian. Location accurate to within 300 m.
Geology: Resource Associates of Alaska (1976) reported molybdenite in veinlets of quartz and pyrite in quartz diorite near contact with granite. Large area of iron-staining due to weathering of pyrite veins and disseminated pyrite and pyrrhotite. MacKevett and Holloway (1977) describe the occurrence as being hosted in a composite Tertiary granitic pluton. Nelson and others (1983, unit Ti17) describe the rocks as uniformly grayish-white, coarse-grained biotite granite with lesser biotite-hornblende granite and granodiorite. There is some magnetite in quartz-magnetite veins. Adjacent granite is not mineralized. Resource Associates of Alaska (1976) reported a sample that yielded 2,200 ppm Mo. Nelson and others (1985) could not confirm the molybdenite occurrence. The age of the granite host rock is Tertiary. Potassium-argon dates on samples from this granitic body range from 35 to 41 m.y. (Reed and Lanphere,1972; 1973).
