From the plans and sections of the mine, it is obvious that, with the shafts as they are, there is much exploratory work to be done. Without a winze on each anticline, from the surface to the depth attained in the shafts, the prospecting work cannot be considered to have been accom­plished. At the No. i shaft, by means of winzes and rises, the eastern centre-country should be bored right through from the suiface to the bot­tom level, and below that level, for in Bendigo winzes are generally sunk for even hundreds of feet below the shaft, for the purpose of prospecting centre-country. The syncline, in a similar way, requires the same treat­ment, so that there may be no chance of missing either an auriferous saddle-reef or a trough-reef. On the 487 ft. 9 in level in the No. 1 shaft, at 435 feet to the west of the shaft, the Energetic centre-country is cut. This should be also risen on and sunk through from the surface to the bottom of the present shaft, or deeper.
In the No. 2 shaft, similar work is needed on the eastern anticline, on the syncline, and on the Energetic line of reefs. With the shafts as they are, and without sinking them deeper, excellent work might be done in the way of exploring the anticlinal lines for saddle-reefs and the synclinal line for trough-reefs.
Until these operations be carried out, the value of the property cannot be known, but the results already obtained fully warrant systematic and thorough prospecting, on the lines indicated.
Below the present depths of the shafts there are thousands of feet of this corrugated country awaiting the miner's advent, and it is now known that for over 4,000 feet in depth of such country as this company holds, payable reefs have been opened up and proved elsewhere.
If the group of mines near the No. 1 shaft were amalgamated, and worked as one mime from the No. 1 shaft, and the No. 2 shaft cut off, and another mine worked from it, mining interests would be benefited. {Report sent in 18th November, 1905.]
Russell's Reef Amalgamated Mine.
Some open cuts have been made about 400 feet to the west of the No. 2 shaft, in search of centre-country, and a small quartz reef, dipping to the west, is exposed. A little gold was obtained. This site would be a good one for sinking to, say, 100 feet to test centre-country. The shaft need not be larger than 6 ft. x 3 ft., unless it be determined to sink to a greater depth.

The No. i South Russell's Mine.
This is a new mine, and a shaft is being sunk on the Energetic line of reef just south of the township of Lauriston. The shaft is 180 feet deep and is 6 feet by 3 feet. In the western cross-cut at 30 feet from the surface, centre-country occurs at 15 feet to the west of the Shaft, while at 38 feet to the west a dyke, a few inches thick, was cut. In the bottom a cross-cut has been driven westerly. , At 43 feet to the west of the shaft the dyke and centre-country are cut. In the latter at centre-country, there are quartz spurs in slate and sandstone beds. The spurs contain iron pyrites and a little galena. One of the spurs contained gold also. Black slate, with pyrites, occurs also in the bottom level. In centre-country a winze, 5 feet deep, has been sunk; this should be continued in centre-country for at least 100 feet. The arch of the anticline is well formed, and saddle-reefs may be met with at any level. If the work so far done is any guide, the plane of the axis appears to be inclined somewhat to the west, but more
