*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 southern and down-dip extensions of the Ura and Murau lodes in Zone 2 below level 1061, which is the lowest level of underground development in Zone 2. Drilling was conducted from one near surface underground drill station on the 1103 level. The Company intersected high-grade mineralization in 14 out of 18 drillholes with three drill holes abandoned.

Drill results include multiple very high-grade assay results, including 325.75 g/t over 0.4 m, 237.58 g/t over 0.4 m, 162.75 g/t over 0.5 m, 126.93 g/t over 0.4 m, and 6,571.20 g/t over 0.45 m , which is the highest-grade assay result ever ret
