" Test at Norfolk Battery. —Two separate tests of two 10-ton parcels were made at this battery, under the most strict supervision. In both tests the value of bullion recovered from the amalgamated copper-plates amounted to 22 per cent, of the original value of the ore. The tailings from one parcel were passed through a double long buddle, and from the other over three Liibrig vanners. " The concentrates in the buddle contained 57 per cent, of the original value of the ore. They have not been treated up to the present time, but judging from the results obtained at the other batteries it seems unlikely that more than half their value will be recovered by ordinary amalgamation, which would bring the total saving somewhat under 50 per cent. " North Star Test.- —The parcel of ore on which this test was made was treated at the Moanataiari battery. It weighed about 20 tons, net dry-weight, and showed the following assay-value per ton :— Oz. dwt. gr.

" The total return from all sources was 430z. 16dwt. of melted bullion, valued at £110 15s. 6d., representing a saving of 40-3 per cent, of the original value of the ore.
