This prospect has very little data after Chapin's 1921 report.
Location: On the northwestern side of Craigie Creek near a small unnamed tributary of Craigie Creek, 1.6 mile northeast of VABM Box. Accurate within 1,500 ft. Locality 4 of Cobb (1972) and locality 4 of MacKevett and Holloway (1977).
Geology: Quartz vein from 6 to 8 ft wide, cuts tonalite country rock. The vein strikes N 85 W, and dips 38 N. It is believed to be the same vein as at War Baby (ARDF number AN003) and Lucky Shot (ARDF number AN002) (Chapin, 1920; 1921). The tonalite is part of the Willow Creek Pluton, a zoned pluton. The outer part consists of hornblende quartz diorite and lesser hornblende tonalite; the core consists of hornblende-biotite granodiorite, and lesser hornblende-biotite quartz monzodiorite and biotite quartz monzonite. Wall-rock alteration within a few inches of the veins is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).
Workings: Chapin (1921) reports that very little work has been done on the prospect.
Age: Late Cretaceous or younger; vein cuts the Late Cretaceous Willow Creek Pluton.
Alteration: Wall-rock alteration within a few inches of the vein is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).
