The West seotion is 30 ft. wide, and tho average assay value is lis. per ton ; the East section about 65 ft. wide, with an average assay value of £1 9s. 6d. per ton. At 75 ft. south a crosscut showed the full width to be 77 ft., of which 10 ft. has an assay value of £1 12s. 3d. per ton. The total distance driven south on the course of the reef is 85 ft. At 75 ft. north the full width of roof is 43 ft., of which 5 ft. assays £1 14s. lid. per ton. No. 11 Level (1,301 ft.). —Salmon West crosscut: This prospecting crosscut was driven 575 ft. from Edward lode. At 249 ft. there is a vein 12 in. wide assaying £3 ss. lid. per ton. The country in the crosscut was mostly oxidized. Kingsford South-east crosscut, situated at 50 ft. east of Lion South-east crosscut, was driven a total of 100$ ft. At 53 ft. the Centre section of Empire lode was intersected ; width 18 ft., and assay value £2 9s. 2d. per ton.

No. 5 Level. —Alexandra lode east of Albert Junction : 291$ ft. was driven. The reef is small and irregular in width. Open cut and Western Smithy level : A considerable tonnage was obtained from these places during the year. Waihi Grand Junction Mine (W. McConachie, Mine-manager).—No. 1 shaft (main) : No. 1 shaft was sunk 100 ft., making a total depth of 1,573 ft. below the surface and 33 ft. below No. 10 level. Prom 1,473 ft. to 1,537 ft. the shaft was sunk through a soft class of country rock. Prom 1,537 ft. to 1,561 ft. the shaft passed through bands of dark breceiatcd soft country rock dipping 10° to the south-east. Prom 1,56.1 ft. to 1,573 ft. is solid country rock. No. 10 level was opened at 100 ft. below No. 9 level and 1,540 ft. below the surface, and sinking below No. 10 level has been resumed. A water-cistern, having a capacity of 12,000 gallons, has been excavated and completed at No. 10 level. The Williams and Robinson stationary pump, which has been operating from No. 9 level, has been transferred to No. 10 level. This pump will now deliver the water to the main station at No. 8 level, and the sinking-pump will discharge its water to the new cistern at No. 10 level. During tho year 117,369,860 gallons of water wore raised to the surface. No. 10 level.—The Main South-oast crosscut was driven a total of 177$ ft. from No. 1 shaft. The crosscut advanced through soft country rock to 59 ft., where a fissure of 2 ft. wide, filled with loose oxidized quartz rubble of no value, was passed through. From this fissure to 70 ft. is country rock. At 70 ft. a fault 8 ft. wide, filled with soft crushed country rock was met. Prom the fault to 113 ft. is soft bedded country rock dipping 40° south-east. Prom 113 ft. to 136 ft. is country rock. At 136 ft. the Empire lode was intersected. The following values were obtained : 136 ft. to 140 ft. is quartz ; value, 3s. Od. per ton. 140 ft. to 148$ ft. is quartz, value, 19s. Bd. per ton. 148$ ft. to 161 ft., a mixture of quartz and country rock ; value, 3s. 4d. per ton. 161 ft. to 166 ft. is country rock. 166 ft. to 169$ ft., quartz, value, ss. 6d. per ton. 169$ ft. to 177$ ft. is footwall country rock.
