777 ft- 5 in. Level.—About 60 feet to the north of the shaft, in die drive between the Nos. 1 and 2 shafts, the cap of the saddle is 7 feet high. The cap of the reef is 12 feet above the saddle, and from about this point northward the anticline pitches to the north, and southward, it pitches to the south. From this point southward the reef has been worked on the saddle and legs for 350 feet in length, and from. 15 to 30 feet in depth. Northwards it has been worked for 400 feet on the saddle and on the western leg down to 40 feet; also from 300 feet down to the back of the 882 ft. 2 in. level, with good ere, from 3 feet to 4 feet thick. Mr. Bell, the manager, told me that where the centre-country pitched to the north the best ore was on the western leg-, and where it pitched to the south the best ore was on the eastern leg. This has been the best saddle-reef worked in the mine. The line of centre country is seen in a cross­cut 180 feet to the east of the No. 2 shaft, but there has not been much work done on it there. At 480 feet to the south of the No. 2 shaft a large fault was met with and driven on for 200 feet, at about 35 degrees E. of S. I think it has caused reversed faulting in the strata by shifting the centre-country on the northern side farther to the east.
The Energetic Anticline.
This saddle reef can be seen on the southern side near a prospecting shaft of the No. 1 South Russell's Company 1,720 feet to the south of the shaft of the South Russell's Company. In the No. 1 South Russell's mine this anticline was worked at 139 feet from the surface by a rise from the 186 ft. 2 in. level, but was not payable; while from 347 feet, at the cap of the saddle, 510 feet to the west of shaft, it was worked both north and south for about 100 feet by a rise from the 425 ft. 9 in. level, but was not payable.
The reef cannot be seen in the workings of the South Russell's mine, but in the Russell's Reef Amalgamated mine it has been worked, at 367 feet from the surface, by a rise from the 487 ft. 9 in. level off the No. 1 shaft, at about 420 feet to the west of the shaft; the workings were from the cap of the reef downward for 18 feet on the western' leg for a distance of 130 feet to the north and the south. The saddle reef worked shows a pitch to the north of 6 feet in 80, or 4 degrees 18 minutes. I was told this reef was not payable. This same line of centre-country is seen in the 247 ft. 6 in. level from, the No. 2 shaft, 400' feet to the west of the shaft. About I mile farther to the north the Energetic line of reef yielded gold to the value of over ,£100,000 to the several companies on the line, not one of which was working at the time of my survey.
No. 2 Shaft.
The No. 2 shaft is situated on the opposite side of the Colihan River, on a bearing of N. 8 deg. 27. min. W., and distance of 1,476. feet from the No. 1 shaft. Four levels are worked at 247 ft. 6 in., 447 ft. 6 in., 706 ft. 11 in., and 776 ft. 3 in., the last being connected by a drive with the No. 1 shaft.
247 ft. 6 in. Level.—This level extends 1,010 feet west of the shaft, and at 400 feet passes through the Energetic line of centre-country. Between the centre-country and the end of the level, the strata all dip to the west. Close to the shaft, on the eastern side, there is a syncline showing, and the crosscut has been carried only for 20 feet further to the east.
447 ft- 6 in- Level.—This level extends eastward from the shaft. From 40 to 68 feet it is in solid quartz, rising in the eastern face on an elevation of 27 degrees for 20 feet, where the quartz is 2 feet thick. This I believe
