Tightly compacted acicular crystals of Jamesonite, an ore of lead.

This historic mining district is one of the world's largest concentrations of silver and has produced over 1.18 billion ounces of silver since 1884. Lead, zince, copper, and antimony has also contributed to over $2.89 billion worth of production. The district is located in the panhandle of Idaho and within the Coeur d'Alene Mountains of the the Bitterroot Range. The mines are hosted by the 1.4 BYA Proterozoic Belt Supergroup rocks.

sulfide  

This is a good representation of the chief ore of molybdenum. It is silvery metallic with a tinge of blue and weighs about 16 oz. Veins can be seen in the sample from 1-20mm.

Because of it's high melting point (2,620 deg. C), it is used primarily in metallurgical applications for harding steel as well as lubricant, petroleum refining, flame retardents, and in the glass and ceramics industries.

REE mineral  

A large, very nice specimen loaded with dozens of reddish brown crystals up to 6mm. 

Monazite is a rare earth phosphate with up to 12% thorium oxide and the primary source of thorium. Thorium is thermally stable and insoluble and used in refractory applications including glass, optics, and ceramics. It is typically mined from off-shore placers mainly in Sri Lanka and India. Specimens with abundant Monaite in rock like this specimen are rare and hard to come, especially from this deposit. The deposit is geologically interesting with unusual characteristics and was published in the a 1961 American Mineralogist.
