Land Status

Land ownership: Federal
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Workings): Surface workings.

Comment (Geology): Central Altered Zone (about 600 x 2,000 meters) contains abundant chlorite, minor biotite, and potassium feldspar, and spotty sericite. Outer Zone (2,000 x 3,000 meters) contains chlorite, epidote, and anhydrite.

Comment (Deposit): Model name = porphyry, vein, stockwork.

Comment (Geology): The prospect is in a large altered zone along the margin of the Nabesna Pluton in an area underlain by Triassic Nikolai Greenstone; both the Nabesna granitic rocks and the Nikolai Greenstone are cut by Tertiary porphyry dikes and small stocks.

Comment (Reserve-Resource): Indicated and inferred tonnage of 500 million tonnes of ore averaging 0.30% CU and 0.02% MO (Richter, Singer, and Cox, 1975, USGS MF-655-K, Loc. 30).

Comment (Development): Bear Creek Mining Company was reported as active on the property in 1981. Prospect has been drilled to a limited extent, surface sampling done by USGS in 1974.

Comment (Location): Best Location: USGS I-789, Location 3; 4 miles east of the Orange Hill deposit. Accurate within 200 feet. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).

Comment (Deposit): Part of Wrangell National Park and Preserve; largest porphyry copper deposit in the Nabesna 1:250,000-scale quadrangle. See also: Orange Hill.

Comment (Deposit): Discovery year: Early 1960's.

Comment (Reserve-Resource): CAPACITY INCLUDED IN ORANGE HILL 0020780015 DEMONSTRATED IN-SITU RESOURCE AS OF 12/31/78 DEMONSTRATED MINEABLE RESERVES ESTIMATED AT: 250,000,000 MT @ 0.30% CU, 0.015% MO

Comment (Commodity): Comparison of surface and subsurface data from the nearby Orange Hill deposit and information from mineral industry sources indicate that the tenor of surface samples is about half of the tenor of subsurface samples, apparently due to surface leaching.

Comment (Ownership): OWNER ADDRESS: BEAR CREEK MINING COMPANY P.O. BOX 9-DISHMAN BRANCH 7821 EAST SPRAGUE AVENUE SPOKANE, WASHINGTON 99213. PHONE: (509) 924-2600 TWX: (509) 328-8570 PGQM SERIES OBTAINED THROUGH PERSONAL COMMUNICATION BETWEEN EVALUATOR AND EXPLORATION MGR- BEAR CREEK MINING COMPANY ALL PGQM SERIES ESTABLISHED USING BEAR CREEK INFORMATION. LANDS WITHDRAWN AS WRANGELL MTS. NATIONAL PRESERVE. PROPOSED BENEFICIATION WITH ORANGE HILL DEPOSIT (0020780015)

Comment (Deposit): Pyrite, chalcopyrite, and minor molybdenite in quartz veinlets and as disseminations in granodiorite and quartz monzonite porphyry.

Comment (Exploration): Status = Inactive
