Mining review . yield of £2 lis. 8d. per ton. It may be pointedout that lack of water and abundance of ore forced the management to resort topicking to enable the battery to be employed as profitably as possible when waterwas available, so that ore broken that would more than pay its way through the millhas perforce been left untreated. From the appearance of the workings the lode itself gives no cause for may be faulted, but faulting does not imply its total loss.

Mining review . yield of £2 lis. 8d. per ton. It may be pointedout that lack of water and abundance of ore forced the management to resort topicking to enable the battery to be employed as profitably as possible when waterwas available, so that ore broken that would more than pay its way through the millhas perforce been left untreated. From the appearance of the workings the lode itself gives no cause for may be faulted, but faulting does not imply its total loss. Indeed, as in the caseof the small fault already seen, a fault may increase the tonnage of ore betweencertain horizons by duplicating the lode. There are some small workings on goldto the S. of the main workings, but it is improbable that they are on the main lodefor reasons already given. The oxidised zone may be expected to continue to considerable depths, as l, of the main shaft the water level was proved 390ft. below the crest of the ridge,while 1,000ft. S. a well did not obtain water at 300ft. below the same To face p. 26 27 The mine is equipped with 10 head of stamps driven by a simple horizontalengine, for which steam is provided by a Lancashire boiler. Other plant includesmasonry water tanks and settling pits and two steel cyanide vats with variousaccessories. Water is obtained from the water shaft, but the supply of SOOgalls. per day isinadequate, and only permits of intermittent work. Throughout the whole historyof the mine the want of water has crippled the undertaking. The water shaft is stated to have pelded 6,000galls. a day, but the supply waslost on deepening the shaft. The bottom of the shaft, 340ft., is in a soft, somewhatpermeable rock below dense quartzite. In view of the success of several bores in similar strata in the district, whichyield supplies of over 10,000galls. a day, it would be advisable to continue the shaftin the softer rock exposed in the shaft bottom. An alternative or supplementary supply could be got by scooping a reservoirnear the water sh
