  further 
  exploration. 
  The 
  site 
  of 
  the 
  hole 
  was 
  chosen 
  purely 
  for 
  

   convenience, 
  and 
  the 
  chances 
  are 
  very 
  remote 
  that 
  the 
  thickest 
  por- 
  

   tion 
  of 
  the 
  bed 
  was 
  encountered 
  by 
  the 
  single 
  test. 
  The 
  dis- 
  

   covery 
  is 
  thus 
  of 
  considerable 
  potential 
  importance. 
  The 
  ore 
  was 
  

   sampled 
  by 
  taking 
  a 
  longitudinal 
  section 
  of 
  the 
  core 
  and 
  an 
  analysis 
  

   by 
  E. 
  Touceda 
  gave 
  the 
  following 
  percentages.
