The Try Fluke Gold Mine was the premier mine on the goldfield in the early 1890's. It also took over the neighbouring Red Mercury, Mariposa, Just-in-Time and John Bull leases, and was active until 1902. The lease contained a battery in the valley below with ore brought from the lower level adit by an aerial tramway. The low level reef was 9 feet wide, ill defined, with a dark friable quartz, while in the upper level the reef was more solid at 5 feet wide.
The main lode became known as the Try Fluke Reef and extended into a number of leases along the line of lode in a north north-east to south-south-west direction, 2-20 feet wide, dipping steeply south-east. The reef contains many cavities with quartz pseudomorphing calcite, sugary quartz, often stained black by manganese oxides. The reef also contains quartz laminae, as thin sheets, book-like, separated from each other by paper thin gaps. Some parts of the reef is decomposed to quartz grit. The richest shoot within the reef was at the spur top, as gossanous material on the surface, with most of the gold very fine.
The first crushing found was 5 tonnes in 1889 for 73 ounces. The following year there was a crushing of 75 tonnes yielding 152 ounces of gold. For the year 1891, the mine produced 7340 tonnes of ore yielding 7537 ounces of gold. It was by far the largest producer on the goldfield at this time.
In 1895, Hugh Murray fell to his death down a winze in the mine. In 1899, his 4 year old son drowned in Kuaotunu Creek.
The mine was sold in 1896 to a London syndicate. John Goldsworthy is mine manager during this period. By this stage the production of gold from the mine was in serious decline, and by 1900 the mine had been amalgamated with other leases, and worked by prospectors.
The mine was part of Bald Spur, a north-south steep sided ridge 2 kilometres south of Kuaotunu. Mindat co-ordinates are approximate. An ore cart from the mine is displayed outside the Kuaotunu Hall.
