Aside from native Platinum Sperrylite is the only platinum ore of any economic importance It forms in highly lustrous crystals that can be very well formed making this mineral a novelty for collectors due to its value Sperrylite is named after Francis Louis Sperry 1861 1906 a chemist who discovered this mineral at Sudbury Ontario in 1889
Current policies aim to establish domestic supply chains of critical minerals for the energy transition The Iron Creek deposit in the Idaho cobalt belt ICB is one of the most promising

In the Blackbird mine area strata bound cobaltite biotite ± tourmaline ore zones are preferentially hosted in biotite rich layers in banded siltite which is deformed into large and small scale chevron style folds that plunge moderately northward The Idaho mineralized zone is hosted by biotite rich rocks in the tightly crumpled hinge zone
The most important deposit in the district is the Blackbird mine which produced copper cobalt ore sporadically from the early 1900 s until about 1960 along the same stratigraphic zone Chalcopyrite cobaltite arsenopyrite pyrite and pyrrhotite are the dominant ore minerals Up to oz Au/ton was present in some of the ore

FINDING MINERALS Where to collect The best place to find minerals is at mines Mines are locations where industrially important rocks minerals and ores as well as precious metals and gemstones are extracted from the earth Mines can produce large amounts of specimens of certain minerals and continue to provide specimens as long as the mine is actively worked
Such mines can be grouped into three categories based on the materials extracted 1 mines of metallic ores iron copper gold lead zinc and silver; 2 non metallic mines and quarries of china clay used in ceramic and tile making gel e saršuy a variety of bentonite used as soap in ancient Iran and bentonite and serpentine used in
