Geologic information

Identification information

Deposit ID 10307417
Record type Site
Current site name Silver Horn

Geographic coordinates

Geographic coordinates: -158.9027, 59.64932 (WGS84)
Relative position This occurrence is on the south side of Silver Horn, a west bay of Lake Beverly. It is in an unnamed drainage that heads on the east side of Akuluktok Peak and flows northeast to the south side of Silver Horn about 1 3/4 mile east of the head of the bay. It is very approximately located, perhaps to within a mile. It is locality 1 of Cobb (1972 [MF 375]).

Comments on the geologic information

  • Geologic Description = Cobb (1972 [MF 375]) identified this as a molybdenum occurrence reported in a written communication from W. H. Waskey in 1935 (probably to J. B. Mertie Jr.). The general area is one where a Cretaceous or Tertiary granitic pluton (Mertie, 1938) sharply intrudes what are probably Middle Jurassic to Lower Cretaceous clastic sedimentary rocks and interbedded volcanic rocks like those in the eastern part of the Hagemeister Island quadrangle (KJvs unit of Hoare and Coonrad, 1978). According to Mertie's (1938) geologic map of this area, most of this unnamed drainage is within the granitic pluton. Eakin (1968) collected stream sediment samples around Silver Horn. The only slightly anomalous molybdenum value (5 ppm) in all of Eakin's samples is from south of Silver Horn; weakly anomalous zinc and several anomalous mercury values were also obtained by Eakin (1968) in his samples south of Silver Horn. Eakin (1968) cautioned that the analytical technique used for his mercury determinations had potential pitfalls. However, field tests showed the expected anomalous mercury results in areas of known mineralization (Red Top mine, DI002) and follow-up geochemical studies (Eakin, 1969) roughly duplicated earlier anomalous mercury results in the southern Lake Aleknagik area.
  • Age = Cretaceous or Tertiary ; mineralization in this area may be related to the Cretaceous or Tertiary granitic pluton that sharply crosscuts clastic sedimentary rocks.
