Historic gold mine. Largest of at least eleven historic gold mines in the Matawai valley, a side tributary in the lower Waiau River valley. The prominent Castle Rock is found at the top of the range at the head of the Matawai Stream. The Matawai Mine was operational intermittently from the time of gold being discovered in 1869 here, until the 1930's. While some minor specimen stone was found in the upper levels, most was low grade ore, and no operation was overly successful. Coarse alluvial gold was found in red gravels of the Matawai Stream. Old overgrown adits may still remain, however the area is rugged, thickly vegetated, and not easily accessible.

Pyrite, electrum, gold, stibnite, galena, sphalerite, and chalcopyrite is found in quartz veins, hosted by propylitic altered greywacke of the Manaia Hill Group.

Gold was discovered here in 1869 by a party of prospectors consisting of George Cornish, William Mathie, Thomas Cull, W.B. Healey, and R.F. Girdis, who were allocated the Matawai reward claim.

The Matawai Gold Mining and Quartz Crushing Company was formed in 1872. The first crushing in 1875, was described as 'unsatisfactory'.

The Matawai Gold Mining Company Limited was formed in 1878, consisting of 17 acres, and the old Golden Belt, Queen of the Tiki, Niagara, and Matawai claims. They intend to repair the existing twelve stamp battery on the property into working order. Semi regular information for the mine was found between 1881 to 1884, mainly descriptions of development work, small crushings, and minor specimen stone. A new battery was erected in 1882. Little information was found for the company after 1884, although a meeting is held early 1896.

Prospectors sent one tonne of ore in 1896 to the Thames School of Mines for testing. Shortly after the Progress Castle Rock Gold Mining Company is formed to undertake development work over several leases in the area including the Matawai. The Matawai section they let to tributers McInerney and party. A battery was erected in 1900. The first crushing by the company in 1900 was for 90 tonnes at 48 ounces, then a second crushing later in the year of 60 tonnes of ore yielded a miserable 9 ounces of gold, and operations were suspended. A further 47 ounces of gold from picked stone emanated from the mine in 1901. The lease was then abandoned, and the battery sold to the Big Beetle Company in 1903, and removed to Gumtown elsewhere on the Coromandel Peninsula.

Prospectors Hovell and Barclay (surnames) found some minor specimen stone in 1925.
