Pook

The Pook is a gold and silver 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 (Workings): Workings / Exploration = In 1981 Resource Associates of Alaska mapped the prospect, collected about 300 samples, conducted magnetometer and EM surveys, and drilled one 365-foot diamond drill hole. The best metal values obtained from the prospect include 0.098 ounce of gold per ton, 1.47 ounces of silver per ton, 210 ppm copper, 1,000 ppm lead, 130 ppm zinc, 300 ppm arsenic, and 0.15 ppm mercury. Eighty percent of rock, soil, and power auger samples collected by Battle Mountain Exploration Company in 1991 contained gold values between 26 ppb and 100 ppb. The remainder lacked gold, except for one sample of Pook vein material, which assayed 0.13 ounce of gold per ton.

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Eocene or younger.

Comment (Reference): Primary Reference = Trujillo and others, 1981

Comment (Deposit): Model Name = Epithermal gold vein

Comment (Geology): Geologic Description = The Pook prospect is in rocks mapped as the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). It is a northeast-striking, gold-bearing pyritic quartz-calcite vein system 10 to 70 feet wide and 2,000 feet long (Trujillo and others, 1981). A trace of chalcopyrite occurs in some of the veins. Individual veins in the system are as much as15 feet thick. The mineralized zone occurs along a fault contact between a basalt flow and a sequence of pyroclastic rocks and andesite flows. The vein material is sheared and crushed and shows evidence of repeated movement, resulting in a complex structural pattern. Anomalous gold values occur throughout the entire length of the zone. The best surface grades are 0.098 ounce of gold per ton, 1.47 ounces of silver per ton, 210 ppm copper, 1,000 ppm lead, 130 ppm zinc, 300 ppm arsenic, and 0.15 ppm mercury (Trujillo and others, 1981). A single drill hole apparently missed this zone at depth but hit a deeper, 76-foot-thick zone. A 35-foot section of this deeper zone assayed 0.005 to 0.020 ounce of gold per ton and 0.02 to 0.06 ounce of silver per ton. In 1991 Battle Mountain Exploration Company collected 26 power auger, 19 rock, and 15 soil samples at the prospect in a 2,600- by 1,000-foot area. Eighty percent of these samples returned low-level gold values between 26 ppb and 100 ppb. One high grade vein sample assayed 0.13 ounce of gold per ton (Ellis and Randolph, 1991).

Comment (Deposit): Other Comments = the prospect is located on land patented by, or interim-conveyed to, the Aleut Corporation.
