Eoal north crosscut was driven a total of 91i ft. from the Martha lode, and, at 82 ft., intersected a north branch of the same lode 2 ft. wide, and worth £1 8s 6d per ton. This was driven on westward for 13 ft. and eastward for 105£ ft. Payable values were met with in both directions N0..9 (23ft.) sub-level, Welcome lode, centre or middle section: A considerable quantity of payable stone has been proved in this section, and the Iris stoping block, about 95 ft. in length, is now being developed Ore that has fallen from Crocodile block on the Royal lode is being drawn off No. 1 Pass block in the Grand Junction area, and 1,839 tons have been obtained. No. 9 (73ft.) sub-level, Martha lode, north sectionDriving, east of Pile pass along the north wall, was done for 120 ft., and, from 50 ft. to 120 ft the quartz was payable for a width of 5 ft. North branch of Martha lode : One hundred and twenty-five feet were driven east of Mule pass on ore of good average value. At 90 ft. east Jamieson winze was sunk to a depth of 60A ft Erom 14 ft. to 38 ft. the ore was of payable grade, but decreased in value with depth. No 8 level • In Pile and Deer arches, on the Martha lode, a total of 4,255 tons were caved. Edward lode : Stoping was finished at 72 ft. up in Roach north block, and 1,079 tons of ore were drawn leaving 1,083 tons yet to be extracted No. 8 level: A shrinkage stope is being prepared in Adder east block, Royal lode, which is estimated to contain 1,740 tons at £1 18s. per ton. No. 7 (105 ft., 80 ft., and 60 ft.) sub-levels : The caving area on the Martha lode had a total output- of 42,186 tons for the year. No. 7 level: The Wliittaker north-west crosscut was advanced from 206 ft. to ft., measuring from the south part of the north branch of the Martha lode with unsatisfactory results. At 395 ft. a reef formation was met. This was tested by Diamond Drill "C" about half-way between this crosscut and surface. White quartz was cut, 2 ft. 9 in. wide of which 16 in of core were recovered assaying Is. per ton.

Giddens rise, situated 235 ft. west of a point 318 ft. west of No. 2 shaft north-west crosscut on a 4in vein which had values, was risen a total of 59J ft. The vein reduced to 3 in. wide and values ranged between £3 15s. Bd. and lis. 4d. per ton. At 50 ft. up a crosscut was driven to the south-east for 614- ft. and at the 50 ft. point, it intersected a sulphide vein of very good value, 13J in. wide. It is evident from its 'dip that this is not the same reef, as Giddens raize was sunk on for 10 ft. below No. 6 level, where the reef is vertical but corresponds with the lode driven on in No. 7 level to the south side of Giddens rise, where the values 'were low. Rising will be done on this lode to locate the bottom of the good values met in the crosscut at 50 ft up No. 7 (88ft.) sub-level: Shrinkage stoping of Osten block on the No. 2 reef was completed. No. 6 level': Giddens south crosscut, situated 100 ft. west of Espir west crosscut (measuring south from the 3in leader that was formerly driven on and thought to be the north branch of the Martha lode), was projected a total of 70f ft.

Driving east of Giddens south crosscut was done for a total of 124J ft. with satisfactory results. This drive was connected to Espir west crosscut on the north side, with 4 ft. of country between the leader and the crosscut.

No. 5 level, Edward lode: Shrinkage stoping was completed in Eel block, which now contains 3,092 tons of broken ore. The west part of this lode was driven on 54 ft. north of Eel west crosscut to the junction with the Edward lode in payable ore, and from 85 ft. to 128 ft. south of Eel west crosscut in low-grade ore about 2 ft, wide. Former driving, to 85 ft. south, was payable. In McEnteer block stoping was completed. Ihe top stope averaged lis. per ton over a stoping width of 3 J ft. North branch of Martha lode : Giddens winze was sunk 61 ft. in reef, about 2 ft. wide, of very good value, and connected to a rise from No 6 level Munro winze was sunk 63f ft. in reef, about 2 ft. wide, of good value, and connected to a rise from No. 6 level Denby winze was sunk 71Jft„ the first 56 ft. in ore of good value, and connected to a rise from r , , C ° rnes rise was P ut U P and connected to a winze from No. 4 level in payable ore. The stoping of Giddens and Cornes south blocks is in progress. No. 4 level, Edward lode: Roach block contains 6,794 tons of broken ore, which is being drawn off. North branch of Martha lode : The drive west of the Gordon northwest crosscut, which was stopped in low-grade ore in 1934 at 506Jft., has been extended west to 668 ft good ore being intersected at several points. At 641 ft, a crosscut was put out in a north-westerly direction for' 42 ft At 38 ft. m quartz 9 m. wide, worth £7 14s. lid. per ton, was met. At 641 ft. Gardiner south-east crosscut was extended for 22ft. ISorth branches of Martha lode: Stoping operations were carried out in Cropp Eallon East, Dutton, and Worth blocks.
