Location and accuracy Only a general location is known for this prospect. But it is probably within a half mile of VABM 4804, which is about 5.2 miles south of the middle of Puntilla Lake and about 0.3 mile north of the center of section 11, T. 22 N., R 18 W.

Geologic setting

Geologic description

Cominco Alaska began mineral exploration in the area in 1986 and may have identified this deposit before they ended their work in 1989. From 2004 to 2006, Kennecott Exploration Company was active in the area and staked several large blocks of ground that included the Snow Ridge prospect. Geoinformatics Exploration Inc. acquired the property from Kennecott, and in 2009, Kiska Metals Corporation, the current holder of the claims, was formed by a merger of Geoinformatics and Rimfire Minerals Corporation.
Little is known about this property other that it is one of the centers of mineralization being explored by Kiska Metals Incorporated in early 2010 (Wahl and others, 2008; Kiska Metals Incorporated, 2010). The regional geologic maps of the area indicates it is near a swarm of andesite dikes that intrude Jurassic to Cretaceous graywacke (Wahl and others, 2008, Wilson and others, 2009). Several gold-copper porphyry deposits are nearby, notably the Whistler prospect (TY022), that may have similar mineralization.
