Comments on the workings information

  • Some Trenching And Diamond Drilling

Comments on development

  • Econ.Com: South Vein Very Promising, More Development Needed To Define South Vein.
  • 1-77 Several Drill Holes Drilled On The Beartrap Property Intersected A Mineralized Zone Matching The Projected Of The Sout (Anderson 1954 P 25-26). If These Intersections Represent T Downward Projection Of The Vein, There Could Be Substantial Spar Resources Along The Structure. Additional Exploration Needed To Determine The Extent Of Mineralization.
