the company let a contract for mining and raising the stone a small profit was shown. The tributers were paid £1 per cubic yard for stone delivered to the paddock, finding all tools, explosives, &c., themselves.
The stone was going underfoot on No. 5 adit, but the company did not consider it worth while to follow it down. A party of tributers was allowed to do so. This party sank a winze about 50 ft., where the stone became very broken and eventually pinched out. A short level was then projected from the foot of the winze, and the stone was stoped out up to the adit. The last crushing from the mine, 250 tons, which yielded 70 oz. gold, evidently came from this part, and if that is so the values were unpayable.
It may be mentioned that in the Inglewood Claim a second vein of about the same length and width occurred parallel to the Inglewood Block and about 6 ft. to 8 ft. in the hanging-wall from it, and contained within a diabase dyke that forms the hanging-wall of the Phoenix and Inglewood shoots. This parallel shoot was traced down to No. 5 adit, but probably cut out below that level in the same way as the other shoot. As far as the writer can learn, both shoots carried similar values.
From a geological viewpoint Dr. Henderson considered (Bull. No. 18, p. 146) it probable that the Phoenix, Inglewood, and North Star shoots originally formed part of the Victoria shoot, and represented fragments displaced from the latter by faulting, an occurrence that could be explained by an east-north-east-striking normal fault, with an angle of dip less than that of the pitch of the shoot cutting off its upper part. There can be no doubt that the three first-mentioned shoots have been faulted, and it is quite likely that the movement was of the nature indicated by Dr. Henderson. It is also highly probable that the vertical pitch of the Phoenix and Inglewood shoots is to be accounted for by twisting or warping of the country due to this faulting.
North Star Mine.—Little is known of this mine beyond the fact that for a short time in the “seventies” a shoot of stone was worked in it on the same line as, and north of, the Inglewood shoot. This was the most northerly stone found on Kelly’s line; but what the length of the shoot was or how far it was followed down are not recorded. It is known, however, that the stone cut out when sunk on, and the depth at which it disappeared must have been very shallow. A small crushing of 215 tons was put through in 1875 for 114 oz. gold, and in 1877 there was a crushing of 100 tons for 76 oz., showing that the stone was not of high grade. In 1879 the company was absorbed by the Inglewood Company, and, except that the No. 4 Inglewood adit was driven through the North Star ground, no further work was ever done on the claim.
Summarizing regarding the various ore-shoots along Kelly’s lode-series, it may be said that the Band of Hope end offers no promise of yielding any satisfactory results to future investigation. There is a strong shoot of stone in the claim of that name, but it has been followed down for 400 ft. below the outcrop without any payable values being revealed. The advance of modern metallurgical knowledge may make it possible for the antimonial ores of the Golden Treasure section to be treated now profitably, but, unfortunately, the data regarding the quantities of this ore available is painfully meagre. It seems evident that there is in the claim a fairly large amount of this ore carrying gold values, but any attempt to estimate the quantity would be merely guessing. It is known that on No. 3 level of the mine the lode was not picked up, but H. A. Gordon’s remark, previously quoted, that no prospecting was done to find it, owing to lack
