SECTION IV.—GENERAL REMARKS. Mining Opekations. Al the Hikurangi Colliery the old sections—-Non. I and 2—have been closed owing to the exhaustion of the coal. Mining during (he year lias been concentrated on section No. 3, of limited area, being the new dip underlying the limestone rocks at Waro. This company, having imported a Sullivan diamond drill, are boring for coal in the vicinity of Grahamstown Wharf, Whangarei Harbour. The output for the year slightly exceeded that for 1910. At the Northern Coal Company's mine operations have been principally confined to the extraction of pillars, which are being exhausted rapidly. The life of the mine has been estimated at about two years. At the Kiripaka Colliery pillar-extraction alone has been carried out. This mine also is approaching exhaustion. The company have located a valuable seam of coal distant about two miles from the present mine, and it is proposed to lay a tramway thereto from the Government railway, and to develop the property. The Taupiri Coal-mines (Limited) : The long drive connecting the Taupiri West with Ralph's Mine has been converted into a haulage-road, from which it is proposed to work the coal from the Lake llotoiti district. The output should be materially increased thereby. The company have recently installed a powerful Tangye winding-engine, together with other important additions to their plant. At this company's Extended Mine, haulage-roads have been constructed in a westerly direction. Preparations are being made to drain the mine by a Cameron pump, with which it is proposed to force the water to the surface through a borehole of 5 in. diameter and 500 ft. in depth.
