. Annual report . trong, the man-ager, gives the following figures showing the development work done during the past year : No. 4 level south was connected with the south air shaft, distant 800 feet south of shaftNo. 1. The Crown Reef ore body has produced a limited amount of ore between No. 2 leveland the surface, but at the depth of No. 4 level 246 feet below the surface, the ore body wasfound to be represented by quartz stringers carrying little or no values, therefore work in thesouth Avorkings has been abandoned. The main ore body in the north workings had been displaced by faulting between the sixthand seventh levels. For the purpose of re-locatinsf the displaced ore body No. 7 level wasdriven northeasterly 328 feet. From this heading diamond drill bore holes were driven north-easterly cutting about 12 feet of quartz and mixed ore at a distance of 266 feet from the c riftheading. The present development work consists in driving No. 7 level to intersect the quartz dis-covered by the diamond [iii]
