states:
"Name: Sir Dominick Mine, Alternative names: No:8 Yudnamutana Group"
"Location: On western bank of Daly Creek, 3/4 mile southeast of the Daly Mine."
"History: It was opened up in 1862 by the Northern Minerals Association and from 1866 to 1868 was one of the properties of the Daly-Stanley Mining Company. At a later date it was held by the Tasmanian Copper Company, and subsequently by tributors.
Further exploration was carried out about 1910 and in 1914 the mine was taken over by the Flinders Copper Mining Company, being known as the No:8 Workings. (Jones 1910, p.24) A small amount of ore was produced in 1918, and work finally ceased in 1920 then the field was abandoned. W.C. 5174 (M.R. 573) of about 40 acres round the mine was taken up on October 9th, 1967 by Kennecott Explorations (Aust.) Pty. Ltd."
Further notes:
Named after Sir Dominick Daly - former governor of SA. (1862 - 1868) - he was also governor of Prince Edward Island Canada (1854 - 1859).
Born on 11 August 1798 at Ardfry, Ireland, Died 19 February 1868, Adelaide, South Australia, Australia. His nephew Dominick Daly was a government surveyor.
The mine names in brackets would appear to be simply mispelled names and not official names for the mine. It is believed people often while looking for the Sir Dominick Mine, come across the Daly first without realising that there is in fact two mines in close proximity. It is interesting to note that there is quite a marked difference in the matrix and geology of the two mines. Even noted by H.Y.L. Brown in 'The Record of Mines of South Australia - 1908'. To add to the confusion there is only ¾ mile or 1.2km between these mines and the official northern boundary of Sir Dominick is the South boundary of Daly.
Although at one stage the Sir Dominick mine was part of the Daly Mining Company, it is a separate mine entirely. The Sir Dominick mine is reached by following the track past the Daly mine and continuing along the creek another 1.7km, the last 500 metres is cut into the side of the hill and is not recommended due to steep washouts. Heavy rains in January 2011 washed away whole sections of the access track along the creek from the Daly mine onwards.
It should be noted that the Catalogue of South Australian Minerals - 1983 refers to the mine as "Sir Dominic Mine".
The mine is best known for excellent samples of malachite pseudomorphs after azurite, with some clusters found up to 10cm across and single crystals 2-3cm across.
Specimens of Olivenite, Malachite, Cornwallite and Cornubite, can be found in a small arsenate zone exposed in the walls and ceiling of one of the adits.
