COPPER  MINES  OF  THE  UNITED  STATES UTAH.

UTAH. 
The  copper  production  of  Utah  for  1905  has  been  estimated  at  57,267,000  pounds,« 
valued  at  $8,785,000.  This  output  comes  mainly  from  the  copper  mines  of  Bingham  and 
Park  City,  the  increase  of  over  13,000,000  pounds  of  copper  over  the  production  for  1904 
being  due  to  these  two  camps.  The  Utah  Consolidated,  of  Bingham,  has  paid  out  over 
$1,000,000  in  dividends  during  the  past  year,  and  the  United  States,  another  copper  pro- 
ducer, $7.50,000  in  dividends. 
The  Bingham  camp  has  been  successfully  developed  until  it  is  now  one  of  the  greatest 
copper  camps  of  the  country.  In  addition  to  the  production  from  the  well-known  flat 
ore  bodies  in  the  limestone,  the  copper-bearing  monzonite  ores  have  been  proved  to  be  of 
great  economic  value.  The  Utah  Copper  Company  and  the  Boston  Consolidated  both 
work  the  so-called  porphyry  or  disseminated  ores,  and  as  the  ore  bodies  can  be  mined  in 
places  by  steam  shovels  and  a  3,000-ton  mill  is  nearly  completed  by  the  Boston  Company, 
a  greatly  increased  output  from  this  source  may  be  expected  in  1906.  The  Utah  Copper 
Company  has  a  plant  of  the  same  capacity  now  in  process  of  erection,  and  it  is  said  that 
these  two  companies  have  over  60,000,000  tons  of  ore  available  for  extraction.  A  third 
group  of  mines  on  this  porphyry  belt  is  that  known  as  the  Starless  group.  All  the  com- 
panies operating  in  this  vicinity  have  enlarged  their  plants,  and  the  output  will  be  greatly 
increased  in  1906. 
Park  City,  which  produces  copper  as  a  by-product,  has  not  been  as  prosperous  as  Bing- 
ham, though  its  output  has  been  maintained  at  about  the  same  point  as  in  the  previous 
year.  The  chief  development  has  been  in  the  Bonanza  Flat  section,  where  the  West  Quincy 
and  Little  Bell  companies  have  carried  on  extensive  development. 
The  Tintic  district  has  shipped  about  300,000  tons  of  ore  from  the  12  chief  mines  in  oper- 
ation, although  there  are  35  shipping  properties.  The  Centennial-Eureka  has,  as  usual, 
been  the  chief  producer. 
At  Alta  extensive  development  work  has  been  done  and  new  ore  bodies  opened  up,  and 
this  once  famous  silver  camp  promises  to  become  second  to  Bingham  as  a  copper  producer 
if  present  indications  do  not  prove  delusive. 
The  Cactus  mine,  in  Beaver  County,  has  been  operated  since  March,  1905,  producing 
about  10,000  tons  of  concentrates  in  1905.  The  company  expects  to  install  steam  shovels 
in  1906,  which  will  greatly  reduce  the  cost  of  mining. 
The  Utah  and  Eastern  Copper  Company  has  blown  in  its  smelter,  in  Washington  County, 
after  some  six  months  of  idleness,  and  as  the  ore  body  has  been  cut  by  a  deep  drain  tunnel, 
the  outlook  is  hopeful  for  a  continued  production.  A  small  smelter  is  also  operated  by 
the  Paymaster  Copper  Company. 
The  production  of  the  State  for  1903  and  1904,  by  counties,  is  as  follows:
