NOTE ON THE OCCURRENOE OF A NEW MINERAL 
AT BROKEN HILL. 
By Epwarp F. Pirrman, A.R.8.M., Government Geologist. 
[Read before the Royal Society of N. 8S. Wales, November 1, 1893. } 
Ir is only a few months since Professor Liversidge read a paper 
(by Mr. C. W. Marsh), before this Society, describing ja new 
mineral which he named ‘marshite.” The composition of the 
mineral was iodide of copper, and.it was discovered by Mr. Marsh 
in the celebrated Aldridge Collection at Broken Hill. I have 
now much pleasure in recording the occurrence of another interest- 
ing mineral from the same district, viz, from the Australian 
Broken Hill Consols Mine. The composition of this mineral is 
sulph-antimonide of cobalt and nickel. The credit of discovering 
the mineral is due to Mr. George Smith, M.a.1.m.z., Sub-Manager 
of the Broken Hill Consols Mine, and it is at his request that I 
am bringing the mineral under the notice of this Society. 
I propose to name the mineral Willyamite (pronounced Willy- 
ah’-mite) after Willyama the official name of the Broken Hill 
township, and the aboriginal word meaning a hill with a broken 
contour. Complete analyses in duplicate of the mineral have been 
made by Mr. J. C. H. Mingaye, r.c.s., Analyst and Assayer to 
the Department of Mines, and the results are as follow :—
