19. Sphalerite or Zincblende. 
This mineral occurs in quantities sufficient for exploitation only at a 
few mines. The principal localities are Silver Hill* and Silver Valley, 
in Davidson comity, and the McMakin Mine,* in Cabarrus county, where 
it is found associated with silver ores ; associated with gold ores at Stewart, 
Lemmond, Long and Moore Mines, and rarely at the Union Mine, in 
Union county ; in limestone at Dobson’s Mine,* Cedar Cove, McDowell 
county, and in Macon county; in small quantities with other ores at 
King’s Mountain Mine,* in Gaston county ; at Clayton, in Johnston 
county, near Marshall, in Madison county, and on Uwliarrie river, David- 
son county. 
20. Char cocite. 
This is also a copper ore, but rarely met with in the State. The mas- 
sive variety lias been found at the Ore Knob Mine, in Ashe county ; also, 
associated with bornite at Gap Creek Mine, Ashe county, the Wary hut* 
and Wolt Creek* Mines in Jackson county, the Gillis Mine* in Person 
county ; also, at the Pioneer Mills Mine in Cabarrus, and in Guilford 
county, as a product of the alteration of other copper ores, rarely with 
silver ores at Silver Hill. 
21. Pyrrhotite. 
Compact pyrrhotite is found at the bottom of the Asbury shaft in Gas- 
ton county, also associated with chalcopyrite at the Elk Knob Mine,* 
Ashe county. 
22. JRhadbite. 
This mineral of meteoric origin has been observed in minute quan- 
ratic prisms of great brilliancy in 'the meteoric iron of Smith’s Moun- 
tain*, Rockingham county. 
23. Pyrite. 
Pyrite is one of the most common minerals of North Carolina. It is 
not only found in globular crystalline masses in many of the marlbeds of 
the eastern counties, but many of the 2&pissoid rocks and slates contain 
it m considerable quantities, and besides it is found in almost every mine 
of the State, In the gold mines the associated pyrite is generally aurif- 
erous. Cubical crystals occur at Hickory, Catawba county, Asbury Mine,
