MINING.

Rose and Shamrock. —The cross-cut from the main adit level has reached the reef, which has been opened on to a small extent. It proves to be eight feet thick, and shows gold in the face. The hopper belonging to the company will be completed in a short time now, and as soon as this is dine they will commence lo break down stone for crushing. Shamrock. —The manager has let a contract for breaking down a hundred fathoms of the reef at £2 per fathom, and the contractors are now hard at it. In a short time a large quantity of stone will be to hand, and crushing will bo started at the Criterion Battery. Criterion Battery. —This machine started yesterday on a parcel of stone from the West Coast tribute, and a parcel from the Waitemata was also to have been commenced on, but owing to the dreadfully bad state of the weather the manager was not able to send stone up the tramway. There is a good parcel ou hand from this mine, which is expected to give a good payable yield. El Dorado. —The result of the crushing of about one hundred and twenty-five tons of stoue for this company at Weston’s Battery is sixty ounces ten pennyweights of melted gold. Sunbeam. —A parcel of twenty-five tons of stone has been crushed at the Tararu Battery for this company, and has yielded thirteen ounces two pennyweights of gold, or ju3t over half-an ounce to the tou. This is from the new shot of gold, and a parcel of some thirty tons from the old shot is about to be crushed at the Tramway Battery in a few days. Caledonian. —A find of some moment was made yesterday in this mine, at the intermediate level close to the No. 1 winze, on the south side of it. Some men were cutting away a corner to enable the men in the No. 2 stopes to put their stuff down the pass, and a fine parcel of about two hundred pounds weight of specimens were

taken out y some of these are very rich, and others again but indifferent, but on the whole they are very good indeed. No change has occurred in the main working on the lode in the intermediate level. A little gold can be seen still, and y-esterday some sixty pounds of picked stuff yvere taken out. The manager intends to sink a winze from the floor of this drive on the reef to the lower-level. This winze will be put doyvn where the best gold was got, and will prove whether the shot runs downwards, as it is supposed to do. Waitemata. —The No. 2 lode is looking better, more stone haviug come in, and gold can be seen freely. Gold is also visible in the No. 1 leader. There are some seventy tons of stone on hand to start crushing with. Golden Calf. —They have cut through the reef in this mine, and proved it to be about seven feet ti ick altogether. A little gold can be seen in the stone, hut no specimens have been taken out. Coliban. —This company have made arrangements to crush a hundred tons at Weston’s battery and will start at sending it down as soon as ever the roads get clear a little after the bad weather.

Nonpareil.— More good golden stone has been taken from the new reef, which the manager now doubts being identical with the Waitemata leader, but rather thinks that it is a branch of his own lode. A new leader has been found in the bang-ing-wall of the bottom level stopes on the main lode. Yesterday, when first met with, it was a mere clay- baud, but when opened out on for a foot or two, it expanded into a fine lode eighteen inches thick of very good loo.king stone, though no gold yvas visible in it. At the adit level the manager has cleaned out the old drive on the No. 2 reef, and put in a cross-cut ftom tho hanging wall for a distance of about tyventy feet. He here found what he was looking for in the old workings on the leader which had formerly- yielded good gold. The reef was found in the face shoyving eighteen inches of good stone, with gold to be seen in it in fair quantities.
