RECENT  SUCCESSFUL  PROSPECTING. 
Since  the  publication  of  the  last  statement  on  this  district,  the 
extensive  exploration  there  described,  which  had  then  been  persist- 
ently carried  on  for  more  than  a  year  without  adequate  results,  has  at 
last  been  rewarded  by  valuable  discoveries.  The  object  of  this 
sketch  is  to  give  an  account  of  the  general  results  of  this  successful 
prospecting  and  of  the  principal  recent  mining  developments.  In 
:he  earlier  statement  it  was  pointed  out  that  as  a  result  of  the  ex- 
tensive exploration  "  some  slightly  mineralized  ground  has  been 
opened,  a  small  amount  of  ore  has  been  discovered,  and  in  the  ground 
which  was  more  wisely  located  the  indications  are  good."tt'  During 
the  last  year  these  indications  have  materialized,  and,  although 
nothing  comparable  with  the  Quincy  strike  is  yet  announced,  new 
3re  bodies  have  been  found,  and  three  of  the  new  properties  have 
3egun  shipments. 
At  the  Kearns-Keith  mine  extensive  beds  of  sulphide  ore  with 
home  carbonate  have  been  discovered  in  the  foot  of  the  main  vein, 
fn  the  course  of  cleaning  out  old  workings  and  connecting  the  mines 
forming  the  present  consolidation,  including  Crescent,  Apex,  and 
lanauer  workings,  considerable  ore  has  been  taken  out  and  the 
nam  vein  has  been  opened  in  new  ground — notably,  to  the  southwest. 
Che  new  concentration  mill,  a  copy  of  one  unit  of  the  Silver  King 
till,  has  been  in  daily  operation  on  the  ores  from  this  property  and 
akes  regular  shipments. 
In  American  Flag  ground  a  strong  ore-bearing  fissure  has  been 
pened  to  a  depth  of  more  than  1,000  feet,  and  at  a  number  of  levels 
or  several  hundred  feet  along  its  strike.  Although  no  attempt  at 
toping  for  regular  shipments  has  yet  been  made,  several  carloads 
f  ore  taken  out  in  the  course  of  development  have  been  shipped. 
hese  yielded  excellent  returns,  indicating  that  the  ore  carries  good 
alues  in  silver,  gold,  and  lead,  and  some  copper. 
In  the  New  York  one  result  of  considerable  exploration  has  been 
e  discovery  on  the  400-foot  level  of  a  fissure,  which,  on  being 
feened  down  to  the  (>00-foot  level  and  below,  has  yielded  several 
jiipments  of  high-grade  silver-lead  ore  with  accessory  gold.  In 
Jhe  Naildriver  prospecting  has  ceased  and  a  reduced  force  has  been 
iking  out  ore  struck  several  years  ago.  The  Scottish  Chief  has 
lade  additional  shipments  of  rich  ore  and  continued  active  explora- 
on.     Some  ore  has  been  extracted    from   the   Comstock  and    Cali-
