Historic gold mine.
Located near the head waters of Sunbeam Creek, adjacent to the historic Dunedin, Day Dawn and Watchman leases. The Mindat co-ordinates are approximate.
The Star of California Reef dips steeply south-east in well bedded andesite flows and dacite breccia, variably propylitised. The quartz veined lode is one to eight feet wide, crustiform and banded. Gold-silver is found in a high value central seam, following a serpentine course through the lode.
Pyrargyrite and polybasite is noted in the deposit. The Au-Ag carrying rhodochrosite and minor rhodonite gives some of the ore a delicate pinkish colour. Pyrolusite is said to be abundant, staining some of the reef black in the upper levels.
Prior to 1887, the lease was a small holding worked by local companies, with some considerable profits from the high grading outcrops, and near surface stone. The Norfolk Gold Mining Company owned the lease between 1888 to 1895.
(Newspaper articles) State the lease was owned from 1895 by the Tararu Creek Company, registered in London, controlling the Norfolk, Sunbeam, Excelsior, and Dunedin mines.
(Fraser, 1910) When inspected in 1908, the Day Dawn and Norfolk leases had been combined under a company called the Day Dawn and Norfolk Mines Limited, registered in London. They controlled the mine from 1896 to at least 1908. The lease contained the Russell battery of no less than sixty stamps, formerly from nearby Tinkers Gully. The New Day Dawn and Norfolk Mines Limited is mentioned in 1912.
