Duggan and Party's Mine, Rewanui.—Coal-production from this mine was confined to the extraction of pillars left behind in the old No. 3 Liverpool State Mine. The work of extraction is nearing completion, and this mine will shortly be closed. Old Runanga Mine (O'Brien and Party), Rewanui. —Three separate mines have been developed at this colliery. In No. 1 Mine two main levels were driven northerly a distance of 21 chains in coal from 4 ft. to 6 ft. in thickness. In No. 2 Mine a pair of parallel levels was driven northerly a distance of 7 chains. In No. 3 Mine the seam overlies No. 2 Mine. Parallel levels were driven 4 chains north-westerly in coal 3 ft. in thickness. Goldlight Colliery (Williams and Party), Rewanui.- —The work of pillar-extraction was continued throughout the year, and an area of approximately 5 acres goafed. No development work was undertaken during the year. Moody Greek Mine (Simpson and Party), Dunollie.—ln the old mine coal-winning operations were suspended and work confined to opening up two new seams east of the present workings. The seams pitch steeply on a grade of approximately 1 in If. Two parallel dip headings were advanced a distance of 4 chains in a southeasterly direction. Parallel levels were then driven a distance of 7 chains south-westerly. The coal, which is of good quality, varies from 6 ft. to 8 ft. in thickness. New Point Elizabeth Mine (Guy and Party), Dunollie. —The work of pillar-extraction between the two faults was continued during the year. A stone-drive was projected in a north-westerly direction through a fault, and a new section was opened out. The coal in the new section was somewhat broken, evidently under the influence of the faulting. Fiery Gross Mine (Currie and Party), Dunollie. —On the north-eastern boundary pillar-extraction was commenced, and the major portion of the output during the year was won from pillar-extraction. Development work : A new drive was opened in coal 4 chains below the old mine workings, and a level driven 3 chains northerly in coal from 3 ft. 6 in. to 4 ft. 6 in. in thickness. Baddeley and Party, Dunollie.—All solid work to the rise having been completed, a dip on a grade of 50° to 65° was driven for a distance of 3 chains easterly and levels broken away and driven in a northerly direction in coal 7 ft. in thickness. Castlepoint Mine, Dunollie. —The bulk of coal won from this mine was from pillar work on the northerly portion of the lease. No development work was undertaken during the year. Hilltop Mine (Armstrong and Party), Ten-mile.—The main dip going south-easterly was stopped adjacent to the fault-line and pillar-extraction commenced in coal from 14 ft. to 16 ft. in thickness. A total area of 7 acres of workable coal standing in pillars remained to be extracted. During November, an outbreak of fire occurred in this mine and was sealed off by means of twelve wooden stoppings covered with brattice, the whole being treated with a wash of three parts of stone-dust to one part of cement. The manager decided that it was advisable to flood the workings in an endeavour to put out the fire. Coal-winning operations were therefore suspended and all material removed from the mine. In December development operations were commenced in a small seam lying to the west of the old mine. Brady and Party's Mine, Ten-mile. —Development work was mainly to the south on the strike of the seam. The coal in the level face gradually increasing in thickness to 9 ft. was of good quality. Conditions at this mine are favourable for economical development. Hunter and Party's Mine, Dunollie. —The output was obtained from pillar-extraction to the east of the main level. No development work was undertaken during the year. Gox Greek Mine (Goates' Lease Worked by Kaye and Party), Twelve-mile. —Pillar-extraction having been completed, the mine closed down. Schultz Greek Mine (Marshall and Party), Twelve-mile.—Development work throughout the year consisted of driving No. 2 incline on a bearing of 17°. The coal-seam varied from 2 ft. to 3 ft. in thickness. All development work to the east was stopped on the fault. Dennehy's Mine, Twelve-mile. —The work of extracting the pillars was continued during the year, the coal being 3 ft. in thickness. Cain's Mine, Rapa,hoe.—The work of pillar-extraction was continued during the year. Development work: Preparations were made to develop a small block of coal lying to the east of the present main drive. Towards the end of the year this work was stopped. A Keith-Blackman fan, capable of producing 25,000 cubic ft. of air per minute, was installed. Bellbird Mine (Fauth and Party), Ten-mile.—The main dip was extended a total distance of 12 chains in a southerly direction, at which point the coal-seam split and thinned. Places driven east and west from the strike of the seam have reached parallel faults 9 chains apart. Bellvue Mine (Hadcroft and Party), Rapahoe.—The work of pillar-extraction was continued throughout the year on the south-western boundary of the lease. During the year two outbreaks of fire occurred in the pillared area, one adjacent to Cain's Mine and one on the eastern boundary of the mine. These were successfully sealed off and coal-winning resumed. Jubilee Mine (Pinn and Party), Rapahoe.—ln the old mine pillar-extraction was continued. Development work : A dip-drive was commenced and projected a distance of 5 chains in a north-easterly direction, the coal being from 4 ft. to 6 ft. in thickness. Musselpoint Mine (Curtis and Party), Nine-mile. —The work of extracting pillars was continued throughout the year. Only a small amount of coal remained to be won at the end of the year. Smith and Party's Mine, Dunollie. —Development work was continued on the strike of the seam, and five levels were advanced in a northerly direction a total distance of 13 chains from the main dip, the coal varying from 4 ft. to 6 ft. in thickness. Braehead Mine (Boote and Party), Dunollie.—Throughout the year pillar-extraction was continued in the north-easterly portion of the lease. Development work : A dip was commenced and driven in a southerly direction for a distance of 5 chains. From the main dip, levels were broken away and driven east and west. Lack of power for haulage purposes prevented the carrying-on of mining operations farther to the dip. Stillwater Mine (Boustridge's), Stillwater. —Development work was carried on in a vertical seam running north and south. The thickness of the seam was extremely variable and stone intrusions seriously hampered mining operations. The coal varied from 18 in. to 8 ft. in thickness, the average thickness being in the vicinity of 4 ft. Remarks on Go-operative Mines in Grey District. No extensive development work was undertaken at any of the mines during the year. Several of the mines are nearing exhaustion, and the proprietors thereof are endeavouring to locate suitable coal-bearing lands for future development. Reeiton Distbiot. Archer's Mines, Gapleston.—ln the No. 1 seam development operations were hampered by lack of power. Pillar-extraction was commenced, and towards the end of the year the mine was abandoned. Hopeful Mine (Archer's Lease). —In No. 1 section, the main level was driven a distance of 375 ft. in a northerly direction when the seam pinched out between the hanging and the foot walls. Stoping operations were then commenced. The coal was extremely friable, having been crushed between two fault-lines. In No. 2 Section a stone-drive was projected 306 ft. in a south-westerly direction in order to reach No. 2 Seam. Coal has not yet been reached. The country is very much broken,
