Aurichalcite : (Zn,Cu)₅[(OH)₃\|CO₃]₂
	Southwest Mine, Bisbee, Warren District, Mule Mts, Cochise Co., Arizona, USA 8.4 x 5.9 x 4.9 cm. More Bisbee material from collector Dave Stoudt - this a matrix containing veins of blue-green aurichalcite, which appears massive at first glance, but is crystalline upon closer inspection. It is odd to see aurichalcite locked in matrix like this; an old specimen from the classic American locality.

Calcite : CaCO₃, Hematite : Fe₂O₃
	Southwest Mine, Bisbee, Warren District, Mule Mts, Cochise Co., Arizona, USA 6.8 x 3.4 x 2.9 cm. Going way back miners at the classic Bisbee locality preserved specimens of the huge variety of calcite found within the mines, as they had no commercial value, but the miners recognized their beauty and variety.

Calcite : CaCO₃, Malachite : Cu₂[(OH)₂\|CO₃]
	Southwest Mine, Bisbee, Warren District, Mule Mts, Cochise Co., Arizona, USA 4.9 x 4.5 x 3.9 cm. Calcite specimens of all sorts of shapes and varieties were saved by miners from the early days at Bisbee, as they had no commercial value and the miners recognized their variety and beauty. This is another out of the Dave Stoudt Collection that had been in the R. Simpson Collection in the 1930s, so it is an old-timer. It is a ...
