Pyrite with Chalcopyrite and Quartz
Lone Tree Mine, Humboldt County, Nevada

Welcome to my Lone Tree Mine Pyrites page!  The specimens
listed here are very rare examples of large, high-quality Pyrite crystals from this mine.  As with most Pyrite from Carlin-Type deposits in Nevada, these cubes contain about 3% Arsenic, which give the crystals a curved, hoppered or even twisted form.  These came from a single find of about a flat of material, late last year.  Anyone who knows the Lone Tree mine, knows that the Pyrites from this famous Gold mine do not normally get to be anything more than druses or crusts.  So, these extra-fine examples came as a great surprise to me!  Not including the additional Quartz and Chalcopyrite associations, they represent some of the BEST Pyrite I have ever seen from Nevada!  Every available specimen that I have is posted here-

These specimens will be mentioned in the
"What's New at Fall Denver 2005" in the Mineralogical Record

Enjoy!    SCOTT
