Strike length varies considerably with elevation, but generally the M Lens has a strikelength of approximately 300 m. All other lenses in the VOK Zone strike 100 m or less inlength.Orebody thickness varies considerably by lens and by elevation but, on average, theM Lens is 25 m thick in the lower elevations (below 1,210 Level), 60 m thick in the midelevations(1,210 to 1,360 Level), and 25 m thick in the higher elevations (above1,360 Level). The other lenses average approximately 20 to 25 m thick, although narrowreserves have been delineated down to a minimum 3 m mining thickness. The remaininglenses also vary but are, on average, approximately 20 m thick. The VOK Zone has aslight plunge towards the east.
