SULVANITE: A NEW MINERAL. 
By G. A. GOYDER. 
[Read June 5, 1900.] 
Some specimens were sent to the Assay Department of the 
Adelaide School of Mines and Industries for assay for copper by 
Mr. E. Meylan, of Port Pirie, = stated that they were obtained 
from a new mine near the Burr 
During the analysis for Bi I found that they contained 
vanadium, and the eds ore wrote for further samples, which Mr. 
Meylan promptly se 
On examination das proved to consist of malachite, azurite, 
vanadium ochre, quartz, caleite, gypsum, and a metallie mineral, 
consisting pe d of copper, sulphur, and vanadium. 
e of this mineral, as free as possible from associated 
minerals, was powdered and digested with acetic acid (which 
removed some malachite and calcite), washed, dried, and 
analysed. There was not su die zu an is cru analysis in

The ratio of copper to vanadium was confir med by a duplicate 
analysis of a smaller sample by a different method of analysis. 
The mineral was found to contain nc paca in the form of 
sulphate, and on heating in a closed tube it gave off no sulphur, 
V,S, in the sample analysed is 34 to L but an analysis of some 
other specimens not so pure proved them to contain an oxidized 
and as the mineral is not distinctly crystalline, and is penetrated 
by oxidised products almost throughout, its physical properties 
cannot be aceurately ascertained. 
*Subsequent analyses show that the mineral is a sulpho-vanadate of 
copper, 3 Cu,S, V,S,.
