The Hannans Star Gold Mine was the most southerly on the Golden Mile. The Boulder Main Reef lease bordered it to the north.
The Hannans Star Gold Mines Limited was floated by the Swan Syndicate in 1895 with 80 000 pounds capital, which gradually increased to 225 000 pounds. A 20 head mill and cyanide plant was erected in 1898. George Robson from the United States was appointed mine manager. Then W.R. Bawden was mine manager until 1906. O.B. Ward was metallurgist, H.J. Carpenter Engineer and H.A. Hack accountant.
There were three main ore bodies on the lease named Main, No. 2, and Morrison's. It was on the same line of lode as the Boulder Main Reef and Great Boulder leases further north. The first two joined at depth, and little work was ever done on the Morrison's lode. 18 acres.
Between 1899 to 1903 the mine produced 34 619 tonnes of ore for 23 293 ounces of gold. The main shaft was at the northern end of the lease, connected with Donoghue's shaft. Ore was extracted from the 75 foot and 175 foot level. This lower level showed sulphide and telluride ore. The mine was the first in the world to use the Diehl process to treat sulpho-telluride ore.
Eli Bull was killed underground in a fall of earth in 1898, and Jason H. White was killed in a fall of earth in 1905.
The company was reconstructed in 1905, then in 1909 amalgamated with the Boulder Deep Levels company. Not all were happy, and a protest meeting in Kalgoorlie was held attended by 400 people. They claimed since 1905, little work had been done on the lease, with the plant used to crush ore for other mines on the Golden Mile.
One newspaper claimed mine manager since 1906, Albert Trewartha James as a 'utter fraud', citing his limited experience with cyanidation on the Rand South Africa, rather than complex refractory ores of the Golden Mile, and lack of mining experience.
The new company in 1909 was called Hannans Star Consolidated Ltd, but it did not last long. In 1910, the lease and plant was bought by Lake View and Star Ltd, with the Hannans company going into liquidation.
