Eagle Creek Mine, Port Clarence District, Nome Borough, Alaska, USA

Location: Eagle Creek is the north-flowing headwater tributary of Right Fork Bluestone River. Sainsbury and others (1969) mapped placer mining operations along 0.9 miles of the main drainage between surface elevations of 550 and about 635 feet (both downstream and upstream of the mouth of Walker Creek, a south tributary to Eagle Creek). These operations start about 2.25 miles upstream of the confluence with Right Fork Bluestone River and 1 mile upstream of the mouth of Bering Creek. This is locality 76 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Eagle Cr.'.
Geology: Bedrock in the Bering Creek drainage is a metapelitic sequence that is locally cut by metamorphosed mafic intrusive bodies (Sainsbury, 1972). The age of this sequence is uncertain but it is probably Paleozoic. At least some placer mining on this part of Eagle Creek is recent compared to that in other areas of the Teller A-3 quadrangle. Sainsbury and others (1969) indicate that mining was taking place in 1968 or 1969. These operations took place along 0.9 miles of the main drainage between surface elevations of 550 and about 635 feet (both downstream and upstream of the mouth of Walker Creek, a south tributary to Eagle Creek). They start about 2.25 miles upstream of the confluence with Right Fork Bluestone River and 1 mile upstream of the mouth of Bering Creek. They were probably dozer and sluice opeations. Cinnabar pebbles are reported to be present in heavy mineral concentrates but otherwise the character of the placer deposit has not been described.
Workings: Placer mining operations, some as recent as 1968 or 1969, took place along 0.9 miles of the main drainage between surface elevations of 550 and about 635 feet (both downstream and upstream of the mouth of Walker Creek, a south tributary to Eagle Creek). They start about 2.25 miles upstream of the confluence with Right Fork Bluestone River and 1 mile upstream of the mouth of Bering Creek. They were probably dozer and sluice opeations.
