Historic gold mine.
Located immediately west of the Ohio Stream prospect, of which it probably shares many of the species of the prospect, as well as those generally mentioned for the Sylvia and Dunedin sections in the Tararu Steam area, however only those specifically mentioned for the Kaiser Reef have been listed.
The Kaiser-Sylvia-Dunedin extending westwards are considered the same lode, and the historic leases were in later years combined. The surface of the Kaiser claim once held a rusty limonite gossan. The lode consists of quartz-sulphide-gold-anhydrite veins, within and adjacent to a porphyry system, located in dilational faults. Sulphides include pyrite, sphalerite, galena, chalcopyrite, and minor tellurides.
Molybdenite occurs as small veinlets in quartz-pyrite veins. The main reef was 3 feet wide. Also mentioned is Harcourts Lode, and Paulls Reef historically. Gold specimen stone was sent to the Auckland exhibition in 1898.
The Kaiser Gold Mining Company worked the mine between 1896-1899, then briefly the Iron Cap Gold Mining Company, producing 126 tonnes of ore. Crushings were processed at the Alburnian company battery. From Harcourts Lode a test batch of ore was sent to the Thames School of Mines, consisting of pure galena, and a few tonnes was also sent to the Dapto smelter at Newcastle (Australia). Modern exploration has determined the reef to be 9.7 metres wide, at an average 4.1 Au g/t, and 25 g/t Ag.
