THE  COPPER  DEPOSITS  OF  THE  EASTERN  UNITED  STATES. 
By  Walter  Harvey  Weed. 
An  investigation  of  the  copper  deposits  of  the  Atlantic  and  Appa- 
lachian States,  begun  by  the  writer  in  1902,  is  still  in  progress.  The 
i) umber  of  localities  at  which  copper  is  known  is  very  great,  but 
there  are  few  mines  now  in  operation,  and  most  of  the  old  workings 
are  filled  with  rubbish  or  are  flooded  and  inaccessible.  Nevertheless, 
the  work  has  progressed  far  enough  to  prove  that  the  deposits  found 
from  Alabama  to  Maine  are  of  many  kinds,  and  while  usually  of 
low  grade  are  sometimes  large  enough  to  be  profitably  worked  under 
present  economic  conditions,  as  is  proved  by  the  successful  operation 
of  the  mines  at  Ducktown,  Tenn.  During  the  last  year  the  writer 
visited  several  properties  in  the  Blue  Ridge  region  of  Virginia,  near 
Front  Royal,  the  "  gossan  lead "  of  southwest  Virginia,  the  Ore 
Knob  and  neighboring  mines  of  northwestern  North  Carolina,  the 
Goldhill,  N.  C,  properties,  and  the  Magruder  (Seminole)  mine  of 
Georgia.  The  results  of  this  and  all  the  field  work  on  the  Appa- 
lachian copper  deposits  will  appear  in  a  bulletin  to  be  published 
early  in  the  year. 
The  Appalachian  copper  deposits  occur  in  two  distinct  fields,  viz, 
the  mountain  region  and  the  Piedmont  Plain  to  the  east.  The  first- 
named  extends  in  a  northeast-southwest  direction,  coincident  with 
the  Allegheny  and  Blue  Ridge  mountains,  from  Pennsylvania 
through  southwestern  Virginia  and  western  North  Carolina  to  the 
i  Ducktown  district  of  Tennessee  and  Georgia.  The  second  extends 
parallel  to  the  first  and  embraces  the  gold  belt  of  Virginia,  Carolina, 
and  Georgia. 
At  the  present  time  mining  work  is  being  carried  on  at  the  follow- 
ing localities:  At  the  Blue  Ridge  district  east  of  the  Shenandoah 
Valley,  near  Front  Royal,  Va.,  and  near  Luray,  Va. ;  at  the  Gold- 
hill  district,  near  Salisbury,  N.  C. ;  the  Virgilina  district,  along 
the  State  line,  TO  miles  east  of  Danville,  Va. ;  at  or  near  Dillwyn, 
Va.;  in  the  hilly  country  of  Floyd,  Carroll,  and  Grayson  counties, 
Va. ;  in  Lincoln  County,  Ga.,  and  last  and  greatest  of  all,  of  course, 
at  Ducktown,  Tenn.
