The minerals associated with the quartz in this vein, especially the cuprite and mispickel, are found most abundantly upon the foot-wall side, or underside of the quartz itself. The smaller accompanying vein before alluded to appears to be but a repetition of the larger one in all its essential characteristics, and is believed by the scientific examiners to be fully as well charged with gold. That this is likely to come up to a very remarkable standard of productiveness, perhaps more so than any known vein in the world, is to be inferred from the official statement in the "Royal Gazette" of Wednesday, January 20, 1864, published by authority, at the Chief Gold-Commissioner's office in Halifax, in which the average yield of the Montague vein for the month of October, 1863, is given as 3 oz. 3 dwt. 4 gr., for November as 3 oz. 10 dwt. 13 gr., and for December as 5 oz. 9 dwt. 8 gr., to the ton of quartz crushed during those months respectively. Nor is the quartz of this vein the only trustworthy source of yield. The underlying slate is filled with bunches of mispickel, not distributed in a sheet, or in any particular order, so far as yet observed, but developed throughout the slate, and varying in size from that of small nuts to many pounds in weight, masses of over fifty pounds having been frequently taken out. This peculiar mineral has always proved highly auriferous in this locality, and a careful search will rarely fail to detect "sights" of the precious metal imbedded in its folds, or lying hidden between its crystalline plates. Nor is the surrounding mass of slate in which this vein is inclosed without abundant evidences of a highly auriferous character. Scales of gold are everywhere to be seen between its laminae, and, when removed and subjected to the processes of "dressing," there can be little doubt of its also yielding a very handsome return. In fact, the entire mass of material which is known to be auriferous is not less than twelve to fifteen inches at the surface, and will doubtless be found, as all experience and analogy in the district have hitherto shown to be the case, to increase very considerably with the increased depth to which the shafts will soon be carried. No difficulties whatever are apprehended here in going to a very considerable depth, as the slate is not hard, and easily permits the miner in his progress to bear in upon it without drilling upon the closer and more tenacious quartz.
