There  are  nowc  on  the  dump  close  to  25,000  tons  of  ore,  of  an  aver- 
age value  of  $50  per  ton. 
Subsequently  ledges  were  cut  in  a  number  of  different  localities, 
such  as  the  Montana  Tonopah,  Mizpah  Extension,  California  Tonopah, 
West  End,  etc.  Some  of  these  are  low  grade,  while  some  show  high 
values.     All  are  in  the  development  stage. 
Besides  the  Mizpah  the  only  mine  in  the  Tonopah  district  proper 
which  has  actually  made  shipments  of  importance,  so  far  as  the 
writer  is  aware,  is  the  Montana  Tonopah,  where  ore  was  discovered 
in  depth  by  prospecting  under  the  later  andesite  capping  after  the 
discover  and  earlier  development  of  the  Mizpah  vein.  The  ship- 
ments'* of  the  Montana  Tonopah  to  and  including  July  15  of  the 
present  year  (1903)  are  as  follows:
