Relative position | The deposit is on the west side of Willoughby Island at an elevation near 450 feet and about 1.5 miles south of the north tip of the island. Accuracy is uncertain. The prospect was not located by MacKevett and others (1971) in 1966. The map site is about the same as location number 96 (Kimball and others, 1978). It is probably correct within 0.1 to 0.2 mile. The site is also about the same as location number 48 of Cobb (1972). Rossman (1963, p. K51) was also uncertain of the location of the deposit, but the prospect was found by Reed (1938). |
