War Baby

The War Baby is a gold 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.

Alterations

Alteration Text: Wall-rock alteration within a few inches of the veins is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).

Comments

Comment (Geology): Geologic Description = Chapin (1920) reported that four or five parallal quartz veins cut the Late Cretaceous Willow Creek Pluton. The Willow Creek Pluton is a zoned pluton: the outer part consists of hornblende quartz diorite and lesser hornblende tonalite; the core consists of hornblende-biotite granodiorite, and lesser hornblende-biotite quartz monzodiorite and biotite quartz monzonite. Wall-rock alteration within a few inches of the veins is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954). Veins generally strike N 80 E, and dip 17 to 62 NW, are found in a 33 ft wide zone, and range in thickness from 1 to 15 inches. Veins appear to belong to a single system that locally branches in the hanging wall. The footwall is marked by slickensides that separate the lode from fresh country rock. The lode is a continuation of the lode at Lucky Shot (ARDF number AN002) that is offset by 600 to 700 ft. The ore mined through 1927 averaged 2.18 oz/ton Au (Ray, 1933).

Comment (Reference): Primary Reference = Chapin, 1920

Comment (Exploration): Status = Inactive

Comment (Production): Production Notes = Production records were combined for the War Baby and the Lucky Shot mine (ARDF number AN002). Both mines were simultaneously operated by Willow Creek Mines. Stoll (1997) estimated the total amount of gold recovered from the Lucky Shot - War Baby vein on the northwest wall of Craigie Creek valley to be 252,000 ounces.

Comment (Geology): Age = Late Cretaceous or younger; veins cut the Late Cretaceous Willow Creek Pluton.

Comment (Workings): Workings / Exploration = Located in 1918, development began almost immediately with the erection of a small mill. The first production from the mine occurred in 1919 after two short tunnels and a crosscut were driven. Willow Creek Mines took over the property in 1921. War Baby was mined, with interruptions, from 1919 until 1940. There were over 2,000 ft of underground workings on 3 levels. Ray (1933) reported that production from 1922 through 1927 was from a single stope measuring 175 by 250 ft with a maximum width of 10 to 12 ft. The ore mined through 1927 averaged 2.18 oz/ton Au (Ray, 1933). There may have been some copper production, however concentrates that were shipped may have come from War Baby or Lucky Shot (ARDF number AN002) (Smith, 1930). By 1950, the mine was long closed and workings were inaccessible (Ray, 1954).

Comment (Deposit): Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)
