Greenough,  owning  the  Morning  mine  near  Mullan ;  the  Hercules 
Mining  Company,  owning  the  Hercules  mine,  and  the  Hecla  Mining 
Company,  owning  the  Hecla  mine,  both  near  Burke.  Other  mines 
which  have  contributed  largely  to  the  general  production  in  the  past, 
although  they  are  not  at  present  being  worked  on  the  same  profitable 
scale  as  those  just  mentioned,  are  the  Helena-Frisco  mine  near  Gem, 
the  Granite  and  Custer  mines  on  the  west  slope  of  Tiger  Peak,  the 
Gold  Hunter  mine  near  Mullan,  the  Sierra  Nevada  mine,  about  a  mile 
west  of  Wardner,  and  the  Crown  Point,  owned  by  the  Coeur  d'Alene 
Development  Company,  also  west  of  Wardner  but  just  outside  of  the 
area  mapped. 
Some  idea  of  the  present  relative  importance  of  the  different  mines 
may  be  had  from  the  following  figures  derived  from  a  table  compiled 
by  Mr.  Stanly  A.  Easton,  manager  of  the  Bunker  Hill  and  Sullivan 
mine,  for  the  Mineral  Industry  for  1903.

The  Bunker  Hill  and  Sullivan  and  the  Last  Chance  mines  are  both 
on  the  same  general  zone  of  Assuring  and  their  workings  connect  at 
several  points.  The  deepest  level  near  Wardner  is  the  Kellogg  Tun- 
nel of  the  Bunker  Hill  and  Sullivan  mine.  This  tunnel,  which  is  a 
crosscut,  runs  southward  from  the  mill,  situated  on  the  South  Fork,] 
about  a  mile  west  of  Kellogg,  for  a  distance  of  about  12,000  feet  to  the] 
Lode.  It  cuts  the  latter  about  2,000  feet  below  the  croppings.  The! 
Morning  mine  has  a  crosscut  adit  2  miles  north  of  Mullan,  the  ore! 
being  brought  down  to  the  mill  on  the  South  Fork-  over  a  narrow-] 
gauge  railway.  A  new  adit,  now  being  run  from  the  mill,  will  cut  the] 
lodes  about  800  feet  below  the  bottom  of  the  present  workings.  The 
Gold  Hunter  mine  is  also  opened  by  a  crosscut  adit,  from  which  two 
a  Mr.  Eastern's  total,  it  may  be  noted,  is  .$1,662,714  lower  than  the  total  value  of  thej 
lead  and  silver  given  for  1003  on  page  290.  The  difference  is  due  to  the  fact  thai  1  lie 
average  price  of  lead  used  by  Mr.  Easton  is  that  received  by  the  mining  companies,  which 
is  considerably  lower  than  the  average  New  York- price  upon  which  the  table  on  page  290 
is  based.     The  difference  is  about  0.6  cent  per  pound.
