Comments on the production information

  • Estimated Production of 21 million pounds Cu. Some" Au and Ag.
  • 200 to 500 tons per day of ore shipped by tramway, with a daily haulage capacity of 984 tons, to Boston-Wyoming Smelter. The Boston-Wyoming Smelter was located at Riverside, south of Encampment along the Encampment River. The Smelter had a capacity of only 500 tons per day. As of 1993, there are no remains of the smelter or concentrating mill. (PIC-32, p. 30)

Deposit Shortly after sale to Penn-Wyoming Copper Company (probably soon after 1897), the mine was the world's 27th largest copper producer. (Hausel, 1997, p. 167)

General From http://www.blackrangeminerals.com/pdfs/2008AnnualReport14Oct08.pdf (Black Range Minerals, 2008 Annual report, p. 13 of 52): Ferris Haggerty Copper Project, Wyoming, USA The Company completed a three hole diamond core drilling programme at the Ferris Haggerty copper project during the second half of 2007. Mineralisation was encounted in all three drill holes with significant intersections including: 2.2m at 5.04% copper, 1.21g/t gold and 5.95g/t silver n 0.4m at 1.72% copper, 0.11g/t gold, >10,000g/t silver and 0.16% nickel The owner of the project was subsequently imprisoned on serious criminal charges. Ownership and control of the project became disputed. Despite considerable efforts the Company has been unable to determine rightful ownership. It has also become evident that the Company could not maintain a reasonable business association with any of the claimants. As such the Company advised that it would withdraw from the project.
