That the Golden Crown reef is remarkably regular in its strike has been lately proved in the shaft of the Otago Company. I have in spected a plan prepared by Mr Mining Sur veyor Wright for that company some time since, by which, through the application of practical and scientific skill, based on the underlie and strike of this reef, the depth the Otago Company bad to sink was named at 237 ft. The outcome of the reef was actually struck within two or three feet of this depth. The striking of the Golden Crown reef in the Otago has given much confidence to the shareholders in the Golden Gate, for, if the reef runs with the same regularity of strike to the S.W. as to the N.E., it must be found to spread across the whole of the Golden Gate Claim. The Otago shaft is placed on the S.E. of the ground, and adjoining the Bed Queen. The Caledonian, Tookey’s, Imperial Crown, and others northward will catch the reef on its underlie. Tbe Cure and Red Queen will get the cap of the reef on which the Manukau Company have been s’o long working. The Golden Crown spur rises to the north east of the claim, its ridge following a N.E. course to the foot of Messenger’s Hill. The reef is supposed to follow a parallel course, and will, in all probability, be found to crop out or come near the surface at the eastern slope of the spur. The Nonpareil and Wai temata are supposed to have struck the reef from the eastern slope of the spur, and which will probably be found in the Hand-in-Hand and other claims between it and Sweeney’s, near which the Dawn of Hope reef from the Moanataiari crosses it, at which point the Golden Crown reef will likely terminate in a dioritic dyke, which forms so prominent a feature in the Harp of Erin and Sweeney’s claims. The reef in these claims has mate rially changed its direction, and is running nearly north and south. I am aware there are those who, not being acquainted with the characteristics of the New Zealand reefs, have prognosticated a con tinuance of this lode for many miles through the country.
