Moke Creek.

This sample of copper pyrites was examined in September, 1873, for Mr. R. Gillies. It was obtained from Moke Creek, near Queenstown, It contains 24 per cent. of the metal, and is the best specimen of copper pyrites yet examined in this laboratory.

Another sample of copper pyrites from Moke Creek and one from Waipori forwarded by Mr. Ulrich, to be tested for gold, were found to contain that metal, apparently in payable quantity, but there was not in either case a sufficiently large quantity sent to determine the gold quantitatively.
