Location and accuracy This site represents three occurrences west and northwest of innermost Kwain Bay. The occurrences are at elevations of 100-300 feet and are distributed along a 0.2-mile-long, northwest-trending, line extending from 0.1 mile west of the marshy flat at the head of the bay. The occurrences are in section 22, T. 78 S., R. 93 E., of the Copper River Meridian. The map site is at the approximate midpoint of this line of occurrences. The site corresponds to loc. 36 in Karl (1992). The location is accurate within 0.1 mile.

Geologic setting

Geologic description

The country rocks at this site are recrystallized, locally semischistose, rhyolite, that is conformably overlain by massive dolomitic limestone (Berg, 1972 [I 684]). These Upper Triassic strata were regionally metamorphosed to greenschist grade in Late Cretaceous time. The occurrences, found by private exploration in the 1970s, reportedly consist of sulfide minerals at or near the rhyolite-carbonate contact. One soil(?) sample near this contact reportedly contained detectable gold (Karl, 1992, loc. 36a-c).
