Item Description
Butte is the Type Locality for only the mineral colusite, which is an uncommon copper sulfosalt. Brassy-metallic colusite crystals to 5 mm (large for the locale) are very richly parallel-bedded in the quartz-rich matrix. Colusite was not named until 1932. Old-time, very fine and rich material from the Charles Velte Collection. valued $200-250
