Update on Exploration: Darnley Bay makes plans for Thrasher zone                                                                                                               Darnley Bay Resources Ltd                                               DBL Shares issued 10,843,508                                 Mar 30 close $0.75 Wed 31 Mar 99                                                  News Release An anonymous director reports Gravity, electromagnetic and magnetic surveys were  carried  out  over  the Thrasher  zone  in  February  and  March  1999,  at a cost of approximately $500,000. Three local conductors were found that are thought to be flat lying and  to occur  at depths of 150 to 400 metres. The nature of the conducting sources is yet to be determined. Other less conductive features have been indicated by  the  results  which may be caused by lithological features at depths of 500 to 1000 metres. Modelling of  the  electromagnetic  data  is  currently under  way  to  interpret  the  geometry  and  nature  of these conductors. Analysis to locate any deeper conductor is continuing. The gravity survey confirmed the steep gradient on the western flank of the Darnley  Bay anomaly, reflecting the large, deep-seated mafic to ultramafic intrusion. The data are currently undergoing final correction and analyses, to determine whether shallower, dense apophyses may be present. Plans are under way to carry out gravity and electromagnetic  surveys  over the  other  magnetic  zones  (Hornaday,  Billy, Green and Ruben) previously identified in the 1997 airborne magnetic survey.  Surveying  of  the  other four  zones  and  findings  from the recent Thrasher survey are expected to result  in  several  targets  which  will  be  drill  tested  beginning  in September. Darnley Bay is currently planning to barge from Hay River to  Paulatuk  all required  equipment  for the drilling and geophysical programs. The company expects to cut its mobilization costs by $300,000 through  barging,  rather than by air transport. The cost of the continuing ground geophysics is estimated  at  $2.0-million with the followup drilling estimated at $5-million. Based on the 1969 gravity data, the 1973 and 1997  aeromagnetic  data,  GSC geological maps, topographical maps and a satellite image of five zones are initially selected for ground electromagnetic and gravity surveys. The ground followup exploration program will  include  a  deep  penetrating time  domain  electromagnetic (UTEM) survey to locate electrical conductors that, in the best case scenario, would be direct indications of ore  zones; and  a  gravity  survey  to obtain more detailed information concerning the location and depth of the heavy rocks causing the anomaly.
