• Two holes, BSDD347 and BSDD351, are existing holesthat were re-entered with a diamond drill rig and theholes extended
• These two holes were targeting the F Shoot, which wasthought 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 thegeometry of these intrusive bodies

• Drilling on this section was targeting the F Shootprojection in the footwall of the B shoot zone
• One new hole, BS17DD386M, and one historicdeepened hole, BSDD308M, were drilled ~300 m apartto test the F Shoot structure. Both holes intersectedwhat is interpreted to be the target
• Additional drilling is planned for 2018 to test betweenthese two intersections
