High quality map of the Hyko Silver mining Co. properties at Pahranagat (Hyko), Nevada. "Map of the Illinois, Rio Virgin, Indiana, Chimney, & Yellow Cocomongo Lodes, Located in the Pah Ranagat Lake Silver Mining District, South Eastern Nevada." E. Ernest, Civil Engr, published by Ferd. Meyer & Co, Lithogrs, 96 Fulton St, NY. Undated (1869) The high quality copy shows the original fold lines. This map is from the Company's annual report. Very rare. 300 feet to thee inch. A later comment by Ross Raymond in 1870 stated the map authors should have shown the Webster property adjacent to the Illinois. The Hyko SMC may have been the NY successor to the Pahranagat SMC of 1865, for which there is a silver first product medal. The map shows the principal quartz vein system, reported at 21 feet wide on top of Silver Mountain, in varying colors as it runs through various mining claims. Interestingly, there are no mine workings shown, but the mill site is shown. 24 x30". shaded relief. Production of this very early, remote eastern Nevada mining district is virtually unknown, since the owners were in New York, and did not report until later years. Early reports of minor production were reported by Couch & Carpenter, but this data appears to have come from a news article in Mi Sci Press. Activity apparently stopped through about 1880, when it restarted under new ownership and remained in intermittent production through about 1912. We have not seen this map preproduced or published anywhere recently to our knowledge. Hyko Nevada
