The Mimosa was a two masted, wooden ketch of 80 tons and it measured 85 feet (25.9m) in length, 22 feet (6.7m) in breadth and 7.2 feet (2.19m) in depth. The vessel was built in 1874 at Shipwrights Point, Huon River, Tasmania. The vessel was owned by Moonta Mines Company.
The Mimosa, Captain W Kerrison, left Port Adelaide in ballast drawing two metres aft and one and a half metres forward. Bound for Moonta Bay, via Stokes Bay, Kangaroo Island, it intended to take in a cargo of timber at Stokes Bay. Wrecked while lying there, half loaded, 14 April 1884.
The Moonta Mining Company only last week suffered another loss in the wreck of the Mimosa, a ketch engaged in loading timber for the Mines; fortunately all hands were saved, though the ketch is fast going to pieces.
