Carr  Fork.  It  is  also  being  opened  by  a  Long  crosscut  tunnel  to 
prove  in  depth  the  character  of  veins  which  have  been  superficially 
prospected.  The  actual  results  oi  exploration  in  these  properties 
arc  reported  to  have  been  most  promising,  but  they  have  not  been 
observed  by  the  writer. 
The  above  statements  indicate  some  of  the  more  important  recent 
development-  in  the  district.  Valuable  ore  bodies  have  been  dis- 
covered in  the  metamorphosed  limestones,  and  a  few  bodies  of  lead 
ore  have  been  encountered  in  exploring  the  fissures.  These  dis- 
coveries have,  as  a  rule,  been  within  the  known  productive  area, 
md  have  resulted  from  the  more  thorough  exploration  of  old  ground. 
There  still  remain  within  this  area  several  very  promising  unexplored 
stretches  of  the  great  ore-bearing  lime-tone-. 
These  recent  exploration-  have  in  a  practical  way  increased  the 
mown  available  copper  resources  of  the  cam})  in  two  direction-: 
First,  the  continuation  in  depth  of  the  great  -hoot  in  the  Highland 
Boy  mine  and  the  proved  persistence  of  it-  copper  values  give  a 
reasonable  expectation  that  similar  ore  -hoot-  may  he  followed  down 
with  profit  in  other  mines;  second,  the  demonstration  by  the  [Jtah 
Copper  Company  that  the  disseminated  ores  in  the  monzonite  bodies 
can  be  worked  at  a  profit  open-  the  field  for  profitable  exploration  of 
fcher  large  copper-bearing  bodies  of  this  rock. 
These  >i<rnificant  recent  developments  indicate  a  probable  continued 
growth  of  the  prosperity  of  the  district  and  an  increase  in  the  output 
for  1005.
