An attempt has been made to intersect the Miner's Dream reef, about 500 feet further south, by driving a tunnel from the Long Gully side of the hill. The tunnel has been started 40 feet above the New Golden Gate Company's race in the abandoned section (439-G), and driven 380 feet in the direction S. 550 W. into the hill, through slate underlying east.

At 158 feet in, a reef formation about 2 feet wide was passed through, consisting of broken slate and three or four bands of quartz, from 2 inches to 7 inches in width, the whole underlying east, at an angle of 70o. It is said to be just gold-bearing.

One hundred and fifty-four feet further in is another reef formation, 2 feet wide, carrying 7 inches of white quartz, also carrying gold, but even less than the first reef.

Seventy feet further is the end. The adit has just been driven far enough to reach the line of the Miner's Dream workings, but it must not be forgotten that those workings will plunge below the level of this adit. The only chance which it seems to me that the adit has, and it is a fair one, is of cutting some reef in the heart of the hill. Judging from the quantity of loose quartz lying on the surface of the ground ahead of the adit face, there ought to be some undiscovered reef between here and the crest of the hill. In addition to this, the position is excellent, being in the centre of the reefing-belt.

Volunteer Consolidated Extended.

This company owns two sections south of the South Miner's Dream, viz., 426-G (8 acres), in the name of G. Webb; and 471-G (10 acres), charted in the name of the company. The work is being carried on upon the latter section. This mine is situate up the Black Horse Gully, about 180 feet above Mathinna. Mr. J. Turner found gold here, and was joined by Mr. Webb and another, but they did not succeed in picking up the reef, and when the company suspended operations on its leases west of the township, it took this claim in hand.

The upper workings comprise an adit driven into the hill north-east for 60 feet, 45 feet of which have been across what appears to be a fault-fissure formation, consisting of rubbly clay, slate and lumps and arched bands of quartzite, mixed with a little vein-quartz. The adit has been driven right across this into slate. At 16 feet in the drive, a crosscut has heen put in N. 38° W. for

17 feet in the course of the formation, which dips northeasterly into the hill; an opposite direction to that of the enclosing slates, which dip south-westerly. From a winze inside the entrance, and 12 feet below the adit, a crosscut was driven for 17 feet south-east, but this is inaccessible. In driving the above adit 23 tons of dirt were crushed at the Volunteer battery, and returned 6 dwts. 18 grs. gold per ton. The width of this formation in the adit is 45 feet. The prevalence of quartzite, and the small quantity of purely vein-quartz, are remarkable. The reason is most likely to be that a bed of sandstone alternated here with the slate. It has been shattered, in all probability, by faulting, and permeated by silica from veins carrying gold.

At the entrance of the adit an underlay shaft has been sunk for 50 feet. At 6 feet from surface the rubble formation was lost, and slate entered. Twelve feet from the bottom of the shaft a small vein, 3 inches wide, of quartz and quartzite was struck, which has expanded from 10 inches to a foot in width, and has been followed south-east for 60 feet on the northern wall of the drive. A little behind the end the stone is a foot wide, but does not carry gold there. At intervals in the drive, it is being bored through with a view of ascertaining its value. The reef does not come away easily from the country; and at my last visit I found it had pinched in the end of the drive, though it still appears to continue. A short crosscut has been put in behind the end, but will have to go a little further to intersect the formation.

At 20 feet from the shaft crosscuts have been drivenone, 29 feet north-east; the other, 28 feet south-west. At a few feet in the south-west crosscut the same rubily formation is met with as was cut in the upper level, but here it is not more than 12 feet widc. It rises in a peculiar manner to 10 feet above the roof, and is then covered by solid slate rock. The veins in it are flat. A little slate underlies it at the entrance to the crosscut, and slate overlies it in the end. The covering of slate may be explained by irregularity of wall of the formation-channel causing overhanging projections of the enclosing slate. Near the entrance to this crosscut is a 5-in. band cf quartz, said to be gold-bearing, underlying the formation and separated from it by a little slate. In the end of the crosscut is slate, with normal dip to the south-west. Although the soft formation closes in over the roof of the drive, I believe it is continuous with the channel intersected in the upper adit.

In the north-east crosscut, which is through slate, dipping south-west, at about 10 feet a little gold-bearing stone was met with in the sole of the drive. In the end a small quartz formation is showing.

The small vein followed in the main drive has been ery persistent, but it is of subordinate importance to the fault-formation, though proportionately richer in gold. The veinstone is for the most part quartzite or sericitised sandstone (wall-rock), veined with a little pure vitreous quartz. The most feasible method of development will be to follow it into the hill, and crosscut west at intervals through the parallel formation until the latter begins to carry solid stone. If this is unsuccessful, sinking will have to be resorted to, for all the gold in the crush-dirt of the formation has certainly come from lode action somewhere in this channel.

A shaft a little higher up the hill is necessary to test this reef-channel at a proper depth.

The formation and vein strike in the direction of the old Telegraph shaft higher up the hill. They are probably parallel to that reef, and this indicates the existence on the property of a zone of reefs running N.W.-S.E., which should be traversed in depth by crosscuts from a main shaft.

This zone is west of the Gate zone.

Telegraph Mine.

About 500 feet south of the Volunteer Consolidated Extended boundary is the old Telegraph shaft, which was sunk 55 feet on a quartz vein 12 to 18 inches wide, running N.W.-S.E. An adit was started to come under the shaft from the east side of the hill, and is said to have passed through unimportant veinlets of quartz, but nothing solid and defined. Work was suspended fifteen years ago, but the continuation of the adit would be good work, as it would prove the hill at a rather favourable point; for the quantity of quartz lying about at surface is considerable, and points to the existence of a yet undiscovered reef. Less than 300 feet more driving is required to bring the adit end under the old shaft.

City Mine.

In the south-west corner of Section 400-93G are the workings of the old City P.A. A tunnel was driven east from the west boundary of the section for about 120 feet, and at 50 feet a wide mullocky formation was struck,

carrying quartz and pyrites. This was driven through for 25 feet, and appeared to strike a few degrees west of north, with an easterly dip. The width of this channel, and its position, have suggested the idea that it may be identical with one of those met with in the east crosscut in the South Gate Mine. The distance between the two is nearly half a mile, and the bearings are not quite the same, but we undoubtedly have here a prolongation of the same reefing-line. The more important matter, however, is to settle the relations of this reef with that of the Jubilee Mine, which is not far to the south.

A small shaft has been sunk at 60 or 70 feet above the adit, but I have no information about it.

Jubilee Mine.

This property comprises four sections-322, 323, 324-G, and 209-93G; in all, 40 acres. It was originally known as the Derby. The Derby Company opened up the mine on the Sections 209 and 322, which are on the Gate axial line, and three-quarters of a mile south of that mine. A good length of reef was worked-about 300 feet on the Derby reef, and nearly 200 feet on the Flat reef. A main shaft (the Derby shaft) was sunk 150 feet, and a crosscut driven to the reef, and some distance south on it, which carried gold at that point, but not enough to be payable. The reef had been stoped up to the surface from creek-level and 40 feet below, with good results. The average yield from the two reefs is reported as having been 1 oz. per ton. Operations were suspended in 1881. The Jubilce Gold Mining Company took over the mine in 1887, and did a little work on the Flat reef, which gave them stone averaging 9 to 10 dwts. per ton. This Flat reef is one which is situated a little farther to the north, but slightly to the east of the main reef, and has at one time connected with the latter at a higher level. This connection has been denuded, and the two are now quite separate. Two tunnels were driven on the Flat reef, and the stone stoped out between them and to surface.

In 1896 the Tasmanian Exploration Company Limited, took over the leases; and in 1897 cleaned out the main shaft to 168 feet, and cut it down and timbered it to the 160-feet level. Sinking was resumed, and the shaft deepened to 272 feet by May in the same year. The mine survey shows that the crosscut south-west from the main shaft intersected the reef at the 160-feet level, at 98 feet

from shaft. From reports which have been kindly placed at my disposal by Mr. H. J. Wise, I gather that the reef at that point was strong, and 3 feet in width. In the drive south the width of the reef decreased to 2 feet, carrying 18 inches of solid mineralised stone, and at 150 feet from crosscut was only 6 inches wide. Driving was discontinued at 177 feet. A winze was sunk for 42 feet from this level below the old stopes overhead; but it only showed clean slate, with a small seam of pug on footwall. The north drive at this level was on a reef 2 to 3 feet wide, but poor; and at 68 feet it showed only 6 inches of stone on footwall side. A large quantity of stone had been taken out previously over the drive and near the surface, and it was thought that the drive would enter payable ground. A slide, however, displaced the stone; and the same displacement was met with in a winze from the floor of this level.

At

The main crosscut was driven to 318 feet from the shaft through slate, which, at 160 feet, changed from green to dark blue, of a very favourable character. 188 feet, bunches of quartz were passed through, letting out a good deal of water; and at 200 feet numerous mineralised quartz leaders were intersected. This quartz zone continued for a width of 70 feet, when clean slate country was again driven in to a distance of 318 feet from the main shaft.

The main crosscut was also driven north-east from the shaft for 38 feet through hard slate with bands of quartz, when, from the plan, a reef-formation would appear to have been struck and driven on north. on north. Where intersected it was 18 inches wide, and well defined. In driving north it widened to 3 feet, between two good hard walls, carrying highly-mineralised stone 2 feet wide, but of poor quality. It was eventually reported as small, and tight for driving.

260-feet Level.-At this level crosscuts have been driven from the main shaft 183 feet south-west, and 38 feet north-east.

On starting the south-west crosscut 4 feet of quartz spurs were driven through, and at 85 feet quartz veins were again passed through for 2 feet. At 112 feet a channel was struck carrying 3 feet of stone, and a drive south was put in on its course for 140 feet. The reef soon fell off in width, and degenerated into bunches of quartz, and eventually to a small leader. All through this drive the stone was of poor quality. The western exten
