ami  general  appearance.  The  composition  of  this  mineral  has  not 
been  determined. 
These  minerals  show  along  croppings  for  about  1,000  feet  along  the 
fracture  zone  and  have  been  found  to  a  depth  of  32  feet  below  the 
surface. 
History  and  development. — These  deposits  have  been  extensively 
prospected  and  opened  along  two  claims,  each  1,500  by  000  feet,  owned 
by  the  Welsh-Lofftus  Uranium  and  Rare  Metals  Company,  and 
slightly  on  adjoining  claims  to  the  north  and  south.  They  are  stated 
to  have  been  discovered  in  March,  1898,  by  a  man  named  Welsh,  and 
prospected  the  same  year  by  James  H.  Lofftus.  After  doing  some 
prospecting  and  making  various  small  shipments  for  testing,  in  June, 
1902,  Mr.  Lofftus  sent  about  500  pounds  to  Buffalo  for  analysis  and 
experiments  in  reduction.  In  September,  1903,  the  material  was  dis- 
covered to  be  radio-active,*7  and  some  was  sent  to  Curie,  at  Paris,  who 
failed  to  affirm  the  presence  of  radium.  In  May,  1903,  the  company 
was  incorporated,  under  the  laws  of  New  York,  to  work  these  deposits 
on  two  claims,  known  as  the  Jesse  D.  No.  1  and  Jesse  D.  No.  2,  and  to 
reduce  the  ores  at  the  company's  experimental  plant  at  Buffalo,  N.  Y. 
The  fracture  zone  along  which  the  property  extends,  and  in  which 
the  vanadiferous  and  uraniferous  minerals  lie,  has  been  opened  at 
about  twenty  places  by  prospect  pits,  short  tunnels,  and  shafts.  The 
principal  development  has  been  at  the  southwest  end  of  the  property, 
where  a  shaft  has  been  sunk  in  the  fracture  to  a  depth  of  32  feet, 
and  levels  have  been  driven  northeastward  along  the  main  mineral- 
ized zone,  at  depths  of  18  and  32  feet,  for  distances  of  18  and  40  feet, 
respectively. 
In  the  course  of  this  development  work  numerous  shipments  of 
cabinet  specimens  and  small  amounts,  aggregating  about  2,000 
pounds,  were  made,  and  in  1904  somewhat  more  than  half  a  carload 
was  shipped  to  Buffalo  for  experimental  purposes.  The  ores  yield 
concentrates  of  uranium  oxide  and  a  high-grade  mixture  of  crystals 
of  the  various  vanadium  minerals. 
The  property  has  never  been  systematically  operated,  but  the  work 
done  shows  the  Avails  of  the  openings  in  the  fracture  zone  to  be  exten- 
sively coated  and  blotched  with  the  vanadiferous  minerals  and  that 
certain  beds  carry  small  masses  of  carnotite.  The  presence  and  grade 
of  the  desirable  minerals  have  been  proved,  but  further  development  is 
required  to  demonstrate  that  the  available  amount  of  this  rare  product 
is  sufficient  to  make  this  property  a  regular  shipper. 
Traces  of  these  minerals  in  this  same  general  fracture  zone  are 
reported  to  have  been  folloAved  from  this  locality  to  deposits  in 
Colorado,  and  also  southwest  from  Richardson  for  several  miles.
