Steiglitz, Victoria.

This auriferous area, about 35 miles S.E. of Ballarat yielded, in the early days of quartz-reef mining, fabulously rich returns from its surface-quartz, and has again come into prominence within the last few years. It occupies an inlier of Lower Silurian slates and sandstones, surrounded on all sides by newer volcanic rocks. The country-rock shows signs of very extensive folding and faulting.

The United Albion Mine.—This is one of the deepest in the district, and has yielded the richest returns. Samples were taken from a cross-cut in the 850-foot level, which extends from the shaft through slates, with occasional interbedded sandstones, for 308 feet. The strata dip steeply towards the shaft until at 220 feet an anticlinal is reached (see k, Table VI.). At 68 feet from the shaft, the footwall of the Albion reef is cut (see d, e, Table VI.). The results of analysis are given in Table VI. and plotted in Diagram 4.

The Tam O'Shanter Mine.—This mine, though not very deep, is interesting by reason of an extensive fault in the strata. Samples were taken from two cross-cuts, one 260 feet below the surface, and running west from the shaft 185 feet; the other an east cross-cut, about 100 feet long, at a depth of 430 feet. The upper cross-cut starts in slates, dipping steeply west, but passes at 31 feet from the shaft a synclinal axis (see i, Table VI. A), beyond which the slates dip steeply E., until, at 83 feet, I a fault-fissure, carrying broken slate and quartz (see e, Table VI., A), is encountered, dipping W.; and beyond this the strata (now alternating slate and sandstone) dip steeply "W, again. The lower or east cross-cut starts in sandstones, with occasional thin beds of slate, all dipping steeply west. At 61 feet, in sandstone, it cuts the gold-bearing vein, dipping steeply E. The dip of the strata does not change beyond this vein, and the cross-cut ends in slate. The results of analysis are page 11 shown in Table VI. A. The remarks upon the previous tables, relative to the country-rock of Bendigo and Ballarat, apply to Tables VI. and VI. A also.
