Spring Creek Molybdenum Project

Project Summary

The Spring Creek claims are approximately 27 miles from Salmon in Lemhi County, Idaho. There is direct access by dirt road.

The elevation is approximately 7800 feet.

Spring Creek Silver-Molybdenum

A high-grade molybdenum project with an extensive vein system

Geology

Spring Creek is located in Proterozoic granite gneiss cut by a series of northeast-trending quartz veins. The veins contain pyrite, molybdenite, galena, and chalcopyrite mineralization.

At least 25 different quartz veins have been identified, some traceable on the surface for up to 3 km and over 600m vertically. The veins intersect at near right angles, converging to focal points that may form large pipe-like targets. Four main mineralized areas have been outlined through historic work, with vein widths ranging from 1.5 to 18 meters.

Exploration Results and Resources

Exploration done during the 1970s and 1980s determined a 500,000 2% MoS2 resource. Later trenching and surface sampling also yielded high-grade results with values up to 2.01% MoS2 and 116 g/t Ag over 4.3 m. 

In the 2000s a company found that the property covers “a series of molybdenum, silver, and copper-bearing quartz veins together with lead and zinc. The mineralization ranges from 5 to 60 feet in width and a strike length in excess of 3 kilometres.”  They concluded that “the work to date on Spring Creek indicates an extensive area, cut by large, up to 18.3 meters (60 feet), well-mineralized veins that have never been properly mapped and analyzed. Previous work focused only on surface-exposed small sections of individual veins.”

This work identified several areas of major veins such as “Vein #1 averaging 6.1m (20 feet) wide with values from underground and surface chip samples ranging from 0.20% to 1.64% MoS2 and silver values from 17 g/ton to 68.6 g/ton (0.50 to 2.00 oz/t). Vein #2 averaging 15.2m (50 feet) in width with values from underground and surface chip samples averaging 0.442% MoS2 and silver values of 44.6 g/ton (1.30 oz Ag/t).” Further analysis of these vein systems is recommended to put together the picture of a potentially large scale molybdenum-silver-copper resource.
