B Shoot South Drilling: 19500 N

19500 N

  • Two holes, BSDD347 and BSDD351, are existing holes

that were re-entered with a diamond drill rig and the holes extended

  • These two holes were targeting the F Shoot, which was

thought to project into the footwall of the B Shoot

  • Both of these holes intersected dioritic intrusive rocks,

where the F Shoot was interpreted to be

  • Further geological work is needed to determine the

geometry of these intrusive bodies

B Shoot South Drilling: 19300 N

19300 N

  • Drilling on this section was targeting the F Shoot

projection in the footwall of the B shoot zone

  • One

new hole, BS17DD386M, and

  • ne

historic deepened hole, BSDD308M, were drilled ~300 m apart to test the F Shoot structure. Both holes intersected what is interpreted to be the target

  • Additional drilling is planned for 2018 to test between

these two intersections
