*Drill intersects are downhole lengths, 3.0 g/t cutoff. True width not known. See Table 1 for additional data.

The primary target of the drill program is the up-dip and down-dip extensions of the UR lodes in Zone 5. Drilling was conducted from two near surface underground drill stations — the 1160 drill station and the 1082 drill station. Drilling from the 1160 drill station primarily targeted mineralization up-dip of the 1150 level, whereas the drilling from 1082 drill station primarily targeted mineralization down dip of the 1066 level. These areas represent the uppermost and lowermost areas of active mining in Zone 5. The Company intersected high-grade min
