The battery is working two shifts daily. The Sylvia Mines Development, Ltd., commenced work twelve months ago, active developmental operations being carried on. Nos. 3 and 4 levels have been restored and retimbered where necessary and ventilation secured. Numerous samples have been taken and assayed along the line of the reef at No. 4 level, and the results have encouraged the company to continue its work. A winze is now being sunk for 120 ft. on the reef at No. 4 level where it has a continuity of over 1000 ft. with an average width of sft. It is the first ore from this winze that is now being treated at the School of Mines. Arrangements have been iriada for the disposal of the concentrates to a Sydney firm. It has been ascertained that the larger proportion of ore bodies between Nos. 4 and 5 levels, containing many thousands of tons of millable ore. is still intact and that ore below No. 5 level has not been touched.
