Conclusion  

Unity  Mining  Limited   27  

  Dargues  Gold  Mine  –  high  grade  intersec,on  in  inferred  resource  increases  confidence  for  down  plunge  extension  

  Near  Mine  Explora,on-­‐    

  Further  understanding  of  geophysical  character  of  Dargues  

  geophysical  surveys  iden,fy  several  promising  targets  

  Regional  Explora,on-­‐    

  re-­‐processing  of  old  data  shed  new  light  

  IP  surveys  iden,fy  new  targets  

  Soil  sampling  iden,fies  new  style  of  mineralisa,on  at  Euradux  

  Booths  Reward-­‐  drilling  to  commence  in  October  to  test  extensions  to  Au  mineralisa,on  

  So  many  targets  !
