The Tamarack 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 = The Tamarack prospect was discovered by grid soil sampling by auger, initiated in 1997 and completed in 1998. As a follow-up to the gold-arsenic-bismuth anomalies discovered in soils, fourteen reverse circulation drill holes totalling 4,747 feet, were completed in the Tamarack area in 1998. Initial drilling consisted of 7 vertical holes followed by 7 angle holes (Freeman and others, 1998).

Comment (Geology): Geologic Description = The Tamarack prospect was discovered by grid soil sampling by auger, initiated in 1997 and completed in 1998 (Freeman and others, 1998). Gold values from 1998 soil sampling were up to 1,986 ppb, with arsenic values to 6,266 ppm, lead values to 9,536 ppm and bismuth values to 18.1 ppm. The strongest gold values were clustered around the old Colbert and Warmbold prospect (ARDF no. LG132) and the Anna Mary prospect (ARDF no. LG130) where northwest striking quartz veins had been mined prior to World War II. Lead values were particularly high over the old Bobbie prospect (ARDF no. LG129) where galena had been noted in old workings, however, gold values from 1998 soils in the Bobbie prospect area were low. Bismuth values are strongest along a 3,000-foot-long N-S trending zone through the Colbert and Warmbold prospect. As a follow-up to the gold-arsenic-bismuth anomalies discovered in soils, fourteen reverse circulation drill holes totalling 4,747 feet, were completed in the Tamarack area in 1998. These were the first drill holes of any kind to be drilled on the Tamarack prospect. Initial drilling consisted of seven vertical holes with follow-up drilling consisting of seven angle holes intended to intercept a combination of structures and areas of interest found during vertical drilling. Eight of the fourteen holes drilled on the prospect encountered significant gold mineralization and all of the holes returned anomalous gold and gold-pathfinder elements.
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Gold-quartz vein.
