Relative position | Poowooliak Point is on the southwest coast of St. Lawrence Island, 3 miles east of the mouth of the Okok River. The site is on a wave cut bench at the base of the sea cliff on the north side of Poowooliak Point. It is located within 1/4 mile and is locality 12 of Cobb (1972). Cobb (1980) summarized relevant references under the name 'Poowooliak Point'. |

Deposit | Model Name = Polymetallic sulfide mineralization in altered volcanic rocks. Deposit model 22c (?); polymetallic veins |
Deposit | Other Comments = Berg and Cobb (1967, p. 9) report the presence of a 1/2 to 2 inch calcite vein containing pyrite, chalcopyrite, galena, pyrrhotite, and sphalerite in a small limestone outcrop at Cape Puguviliak (a former name for Poovooiliak Point, Cobb, 1980, p. 58). The source of this description is not identified. The mineralization described by Berg and Cobb (1967) may be in the nearby Triassic to Permian age mafic Permo-Triassic assemblage and a different occurrence than that described and sampled by Patton and Csejtey (1971). |
