Location: The exact location of this prospect in the Hattie Creek drainage is unknown, but it is presumed to be north of the creek where a small igneous body is mapped at the coordinates given. Hattie Creek is a tributary of O'Connor Creek about 7 miles west-northwest of Fox ; the prospect is shown on the south side of the Old Murphy Dome road in the SE1/4 sec. 23, T. 2 N., R. 2 W., Fairbanks Meridian.
Geology: This prospect consists of a gold-bearing igneous body that has been mapped by Newberry and others (1996) as a Cretaceous altered dike. This map unit contains altered quartz porphyry, tonalite, granodiorite, and undifferentiated mafic dikes. Grateful Dog Mining investigated this igneous body by drilling and using geochemical and magnetometer techniques (Bundtzen and others, 1990, p. 12). These investigations resulted in the definition of anomalous thorium, niobium, tantalum, and rare-earth elements in stockwork-like fissures in metaplutonic(?) rocks of the area (Bundtzen and others, 1987, p. 8).
Workings: In 1988 and 1989, Grateful Dog Mining investigated an igneous body using geochemical, magnetometer, and electromagnetic techniques, and also dug test pits and drilling it (Bundtzen and others, 1987, p. 8; Bundtzen and others, 1990, p. 12).
Alteration: Cretaceous dike is altered and iron-stained.
