April. Crown (Karangahake).—The new find on the river level promises extremely well, as gold is showing freely. Mr McGruer has the majority of the staff there. The level is seven hundred feet below Captain Coward's.[1] May. Crown: A start has been made connect the new find with the reduction works. This will be done by means of a ground tramway of about 20 chains, utilising the old Monastery line (which property the Crown Company have recently purchased). The ore will then be sent on to the stone-breaker floor by means of a hoist similar to that now being used for hoisting the ground ore to the Cassel Company’s works.[2] 25 June. In the Crown mine (Karangahake) Mr McGruer has finished a connection between the new Waitawheta reef and the mill.[3] |

August. The tramway leading from the mine to the new mill site (the Waitawheta Road) is completed. [4] |

March. Compressor at old Crown battery site working. [5] Therefore an air pipe will enter the adit. |

Early. The new air compressing plant in the “Crown Stope” started. [6] |

1899 |
Early. The manager has altered the names of the levels, in order to save confusion. The No. 6 level in future will be known as the Waitawheta tunnel.[7] |

March. A splendid pump has been installed. The machinery for pumping and winding is such that almost every contingency is guarded against. [8] This is all run by compressed air. The whole of the company's underground machinery is now worked by a powerful air-compressor, and it is doubtful if a more complete and up-to-date plant is to be found on the Australasian goldfields.

July. Consequent upon the continued lowlevel exploitations and the opening up of new blocks, it was found that the demand upon the motive power was too great to keep all the plant—such as pneumatic engines, Cameron pumps, and rock-drills— working continuously, and so the management decided to augment the power by an auxiliary steam plant. A large Babcock boiler was therefore installed at the mine. Provision has also been made in the boilerhouse for another boiler, which will probably be erected shortly.[10] This is the concrete pillbox perched on the cliff beside the Waitawheta entrance to the mine. |
