and can be traced for miles to the north and south. Its southern extension is known in one part as the Bet Bet, and here are the remains of much shallow works for rich returns. No real mining-has been carried out anywhere on its line, the quartz occurrences of which await the coming miner. This line of lode systems is only one of many whose outcrops show in the surrounding ranges, none of which have been sampled. In the town itself a first-class crushing mill, with twenty 1,000-lb. heads, Gates'rook breakers, automatic feeders, and Wiltley tables, remains motionless, and this on the outcrops of another system of golden lodes, on which there is a splendid winding plant. A shaft sunk 1(50 feet is equipped with a 10-in. pumping column and a 10-in. engine. This first-class equipment, practically new, is unfortunately idle. The lode structure here is of the enlarged wing class, inclining to the west in strata dipping east. Thus the minor lines of drainage in the gold-slate underlie at about
right angles to the underlay of the lode, and the slate bars being alternate with . bars of sandstone, the stone is rich or poor according to its contact with slate or sandstone. A high-grade surface patch, associated with slate, worked here, in the first place, apparently led to the expectation of long and continuous mining on ounce stone. Disappoint­ment was consequently felt when the average proved to be low even in dwts. Even in the shallow works opened there are evidences of managers having done their best to realize the average ex-"pected — searching for patches at a greater cost per ounce of gold won than would have been the case had they mined great widths of the lode with its wall country en masse. This striving for big average yields in lodes having in­termittent deposition is a mistake. Better have a continuous 5s. per ounce from low-grade ore, worked systematically, than an occasional 20s. per ounce from a lode being "rooted" for its richer parts. This venture was con­ducted by an English company, designated the Mother o' Gold Consolidated Mines Limited, and it was known as the Church Union mine. There are great widths of payable low-grade ore in its area, with a large proportion of gold-slate situated on either side of the channels in which the quartz is stored. I found slate in the mullock heap containing fine gold distri­buted in its layers—layers which represent the many lines of drainage that feed into the "filter packs" represented by the wide "makes" of stone, and by the floors, carrying vein quartz, going out from the main bodies of quartz to the east and west. Not less than 40 heads of stampers should be going here, crushing ore from at least 30-ft. widths of gold-bearing material. Forty heads would treat 1,000 tons per week, and the cost all told, mining and treatment, should not exceed £400. This means 2 dwts. to the ton. A shilling per ton profit means 5 per cent, on £50,000. The question now arises whether or not can 2-1/4 dwts. to the ton be got from this Church Union mine ? I think the residents of Eunolly and its neighbourhood should give this matter attention, considering that there is a full equipment of ore-raising, ore-treating, and water-pumping facilities
