Feasibility Study and Technical Report - Pretivm

14.0 MINERAL RESOURCE ESTIMATESSnowden previously completed mineral resource estimates for different areas of theProject. Initially (September 2012), these estimates were aimed at evaluating thebroader lower-grade mineralized areas including Bridge Zone, Gossan Hill, and ShoreZone (Olssen and Jones 2012b). No estimates have been prepared for these zones toconsider the potential for underground extraction.More recent estimates, also completed by Snowden, were focused on evaluating thehigher-grade areas. These estimates were reported at a high-grade cut-off for potentialunderground extraction. They include:• a mineral resource estimate for West Zone (Olssen and Jones 2012a)• a mineral resource estimate for the VOK mineralized area (Olssen and Jones2012c).14.1 DISCLOSUREThe mineral resources were prepared by Snowden under the supervision of QP IvorJones, Executive Consultant and an employee of Snowden Mining Industry ConsultantsInc.
