And the following day, with the same object, I examined the country more to the south-west; but without making any discoveries indicating the actual existence of coal-seams. On the 24th December I returned to Dunedin. The Nenthorn reefing district seems to form part of a much larger region over which auriferous lodes and the ores of other metals are found. This, even within bounds less than the actual limits, may be said to extend from Highlay Hill, by way of Macrae's Flat and the Nenthorn valley, to the 'l'aieri River, and thence in a direct line to the Upper Waipori, where gold, copper, and antimony lodes are known, and are being--or have been--worked. Within this belt of country the reefs, with few exceptions, trend nearly E.--W., and dip to N. at high angles generally, although in the amount and direction of the dip there are also a few exceptions to the general rule. There seems to be no definite limit to the reefs in the direction of their strike, the limits of the mineralised country in an east-and-west direction not yet being determined. To the eastward reefs are found in the schistose country till where this disappears under the Cretaceo-tertiary rocks developed along the coast-line of eastern Otago. To the westward it is reported that quartz reefs of a similar character, and trending in the same general direction, are not rare in the Taieri Ridge, on the east side of Strath-Taieri, and in all probability the same system of fissures and reefs is to be found in the Rock and Pillar Range, on the opposite side of the valley. While thus the belt of country over which reefs are found has a considerable breadth, there is, on...
