|Location and accuracy||Prospect is on the southwestern flank of Kijik Mountain. Locality 20 of Nelson and others (1985) and locality 14 of MacKevett and Holloway (1977). NE1/4SW1/4 sec. 24, T. 3 N., R. 29 W., of the Seward Meridian. Locality accurate within 400 m.|
Geologic descriptionMolybdenum claim in rhyolite and associated granite bodies (Nelson and others, 1983; unit Tv). Unit Tv includes rhyolitic breccia, ash-flow tuff, flows, and intrusive rocks and subordinate mafic to intermediate flows. MacKevett and Holloway (1977) speculated that the claim is located in an area of quartz veining. Potassium-argon ages for Unit Tv range from 56.2 to 62.7 m.y. (Eakins and others, 1978).
