levels towards the junction of the Inangahua and Buller Rivers. He also made a special report on an antimony lode at Reefton, showing that an outcrop had been found which was about eighteen inches thick, and the reef had been driven on for 150 feet from that point without antimony being found. Heavy lodes of antimony are, however, found in several of the auriferous claims from Rainy Creek to Boatman's, which, in all cases containing gold, are treated in the ordinary way for the extraction of this alone, all the antimony and probably much of the gold being thus sluiced away. An examination of the auriferous cements at the head of Lankey's Gully showed that tinstone undoubtedly occurred associated with these in small quantities, but bad weather prevented any attempt being made to trace this back to its parent rock. He visited Langdon's Reef, near Greymouth, and reports that the thickness of the reef, at present being worked, is about two feet nine inches, which, being less than it was at the outcrop, shows the lode to be of a bunchy character.
The outcrops of coal in Coal Creek, Greyrnouth, were also examined, and he reports that two seams of coal 6 feet and 10 feet in thickness respectively, occur in the lease, in which a considerable quantity can be worked level free. In the month of June Mr. McKay paid a visit to the Terawhiti reefs, and reports that the Albion claim possesses a reef of an average thickness of from 18 inches to 2 feet, which has been followed along its strike for a distance of 6 chains, and for a depth of 130 feet. Some assays of quartz from this claim have yielded over 3 ozs. of gold per ton, but the specimen brought by Mr. McKay gave nothing but traces of the precious metal.
