THAMES DEEP LEVELS. The pumping plant at the Thames Hauraki shaft ceased operations shortly before noon on Thursday under orders" of the Drainage Board, and this finally stops all operations at the I.COOtt level, both by the. Deep Levels Mining Board and the May Queen Gold Mining Company. It will be the means of throwing quite a number of miners out of employment, in addition to the engine-drivers and staff who were employed about the pumping plant itself. The •Herald’ states that it will eventually prevent any mining operations from being carried on within the limits of the drainage area on the flat, as the- water will gradually rise until even the upper levels will become flooded and useless in the course of a few months.
After a record run of dredging time the Rising Sun dredge last week entered upon a month’s overhaul and repair. The Roaring Meg Hydraulic Company were, from latest reports, still engaged in endeavoring to ascertain the depth of the ground, which proved deeper than was at first, anticipated.
The Confidence dredge, above Lowborn Creek, recently passed into the hands of several local drodgemen. Tho machine ia now at work, but operations are so far restricted to one shift a day.
Nevis still continues to lead the way as a mining field, and many more years’ profitable work in this locality can be expected. Already this season some promising reports are to hand. The Lower Nevis Hydraulic Company are now lifting the first wash-up, while Graham and party, at Upper Nevis, are also reported to be on encouraging prospects. Both Rise and Shine dredges are having steady runs, with satisfactory results. No. 2 last week encountered rising ground and indications of wash in place of the deep gutter worked during the last three weeks, and returns are likely to improve in consequence. The master of the Shine dredge (Mr C. Brest) has recently patented an improved gold-saving mat from an original idea. Tliis has been put to an exhaustive test during the past 12 months with excellent results, and appears specially adapted for treating ground in which black sand abounds. It appears to have won very favorable opinions from mining men generally. The matting is constructed so as to give a continuous ripple, with intervals of about three-quarters of an inch, for tho whole length; while in forming tho ripple a depression is also left on tho surface, and in this the gold lodges, practically free from blak sand.—Own correspondent.
