The Pilgrim is a gold, silver, and copper mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Reference): Primary Reference = Newberry and others, 1986
Comment (Geology): Age = Devonian based on reported Early Devonian Pb/Pb zircon ages from the associated Baby Creek batholith and Horace Mountain plutons (Dillon and others, 1996).
Comment (Workings): Workings / Exploration = Claims located in 1972.
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Cu skarn deposits (Cox and Singer, 1986; model 18b)
Comment (Deposit): Other Comments = See also: Mike (CH100), Vicki (CH097), Evelyn Lee (CH059), Luna (CH101), Victor (CH064), and Ginger (CH060). In early reports (DeYoung, 1978) the Pilgrim prospect is grouped with the Cindy, Mike, and Vicki prospects.
Comment (Geology): Geologic Description = The Pilgrim occurrence is one of four previously grouped occurrences which, in addition to Pilgrim, included Vicki (CH097), Cindy (CH098), and Mike (CH100) (DeYoung, 1978). Newberry and others (1986) described in general a group of skarn prospects in the Chandalar area that includes the Pilgrim occurrence. This group of skarns is northwest of a belt of Devonian(?) granitic rocks informally named the Horace Mountain plutons. Many of the skarns exhibit both prograde and retrograde mineral assemblages. Newberry and others (1986) stated that the mineralogy, mineralization, and alteration of these skarns categorize them as continental-margin, porphyry-related copper skarns. Early data on these prospects (as a group) indicated the presence of small amounts of tactite-associated copper mineralization (DeYoung, 1978). Newberry and others (1986) classified the Pilgrim prospect as a Cu-Zn-Pb deposit, and Newberry and others (1997) classify it as a calcic Cu skarn. The mineralogy of a specimen from the Pilgrim prospect includes garnet, epidote, actinolite, pyrite, sphalerite, and chalcopyrite (Newberry and others, 1986). Analyses of this specimen ran 12.4 percent Cu, 0.24 percent Zn, and 71 ppm Ag. A listing for the Pilgrim prospect on the Ventures Resource Corporation (currently exploring Doyon, Limited lands in the Chandalar area) website (1998, URL http://www.venturesresource.com/) classifies it as a Cu-Au deposit, although no supporting data are given.
