Alteration

  • (Local) Wall-rock alteration within a few inches of the veins is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).

Comments on the geologic information

  • Geologic Description = Gold-bearing quartz veins cut early Paleocene to Late Cretaceous tonalite. Lithologies of this unit includes: biotite-hornblende tonalite and lesser biotite-hornblende quartz diorite. Wall-rock alteration within a few inches of the veins is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954). Assays from samples taken along drifts showed mostly marginal gold values, a few had 0.75 oz/ton Au (Stoll, 1997).
  • Age = Late Cretaceous or younger; veins cut early Paleocene to Late Cretaceous tonalites.

Comments on the workings information

  • Workings / Exploration = In the early 1930's, under the management of William G. Smith (Gold Top Syndicate), a steep aerial tramway was strung from Craigie Creek to the prospect - an elevation difference of 1,300 ft. Smith drove an adit (Smith tunnel) 285 ft to reach the Gold Top vein. Drifts both east and west followed the vein for a total of 850 ft. Amount of work done on prospect might indicate the presence of some gold, however it was never reported and apparently was not economical (Smith, 1934). Forty assays that had been made from samples taken along the east and west drifts in 1940 showed mostly marginal gold values, a few had 0.75 oz/ton Au (Stoll, 1997).

General comments

Subject category Comment text
Deposit Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)
Deposit Other Comments = Besides being one of the longest traceable vein outcrops in the district, the Gold Top lode had the distinction of attracting more prospectors and promoters than any other lode on the gold belt, all without becoming a producing mine (Stoll, 1997).
