Gaston county, Soapstone Quarry, twelve miles northeast of Statesville, 
Silver Hill, Gold Hill and many other localities. Combinations of cubes 
and octahedra are found at Clegg's Mine, Chatham county, and in the 
Guilford county gold and copper mines ; the pyritohedron, often in com- 
bination with cubical and octrahedral planes, is found at the Stewart 
Mine, in Union county, Cambridge Mine, Guilford county, Long Creek 
Mine, Gaston county, ! udesill Mine, Mecklenburg county, etc. Large 
veins of compact pyrite occur in Gaston county. 
27. Chalcopyrite. 
This is very abundant, and indeed is the only reliableQcopper ore of 
Xorth Carolina. It lias been found in fine crystals at the Gardener Hill 
Mine, probably also at other copper mines of Guilford county. It is the 
ore of all the gold mines, which in depth change into copper mines in 
Guilford, < abarrus and Mecklenburg counties.; also at the Clegg’s Mine* 
in Chatham county, the Conrad Hill and Emmons Mine* in Davidson 
county; Peach Bottom, Alleghany county; the copper mines of Macon* 
and Jackson* counties ; at many other localities it is found associated 
with other ores. 
25. Baeniiakdtite. 
A peculiar and rich copper ore, first noticed on Daniel Earnhardt’s 
land, and then at the Pioneer Mills Mine in Cabarrus county. It also 
occurs at the Cambridge Mine, in Guilford county, and the Wilson Mine 
and the McGinn Mine, in Mecklenburg county. The true barnhardtite 
contains forty-eight per cent, of copper ; there is another copper ore, 
sometimes associated with it, which contains forty-eight per cent, of 
copper. It appears to be uniform and does not look’like a mixture. Its 
true character is not yet established. 
26. Marcasite. 
According to the infermation received from Dr. Asbury, of Char- 
lotte, this mineral occurs in Iredell county. 
27. Leijcopyeite. 
It has been observed by Dr. Asbury at the Asbury Mine, in Gaston 
county.
