Historic gold mine.

Mining was conducted both sides of the Waitawheta River, a side gorge off the Ohinemura River. The mine accessed the Crown and Welcome veins.

The Crown Company was formed in 1883, but operations at the beginning were difficult due to the refractory nature of the ore. Mining concentrated on the upper most level called 5A. The lowest level was still 500 feet above the river level. They erected an inclined tramway from the mine to the battery to transport ore.

In 1891, they commenced mining of the Welcome Reef, driving an adit 2894 feet. In 1896 a shaft was sunk from a chamber within this level for 526 feet, and developed five levels from it. The lower levels suffered flooding problems.

The company gradually took over neighbouring claims, increasing from an initial 60 acres to 404 acres. These leases included the Earl of Glasgow, Monastery, Mammoth, and Ravenswood.

The introduction of the cyanide process in the 1890's improved extraction rates, however profitability declined from 1910 to 1915. In 1916, the mine was taken over by tributers, until 1920 when much of the machinery was dismantled. Very small scale mining continued until 1928, when the company abandoned the lease.

Impressive battery ruins remain to be seen along the Waitawheta Windows walkway. The Talisman and Woodstock battery ruins, adits, railway tunnels, ore carts and other mining relics are in the area.
