Copper. 
Ores of this metal are met with at Buchan, Mount Tara, Accommodation 
Creek, and elsewhere. Probably many localities exist that will only be 
searched for when there is a prospect of working such ores at a profit. 
Very little has been done so far in opening out the copper sites discovered- 
Lead. 
Galena is the most usual ore, and is met with at Back Creek, Buchan, 
Murrindal, Mount Deddick, and many other localities. 
Tin. 
Cassiterite occurs north of Bruthen, but nothing very valuable has been 
so far discovered. Further search should be made for this very valuable 
ore. 
Iron. 
At Nowa Nowa, the largest deposit of iron ore (haematite) known to 
occur in the Stalte exists. About 8 miles further north is the “ Iron 
Mask,” another extensive deposit of manganiflerous iron ore that covers 
an area of about three acres. At present it is being worked for manganese 
ore. Several other deposits of iron-ore of less magnitude occur in the 
vicinity of the “ Iron Mask, and between it and Nowa Nowa. Mr. 
Jenkins reported very favourably on these. 
Marble. 
A deposit of marble that is but little known has been found about 25 
miles north of Orbost, and has been brought under notice by Mr. James 
Cameron, M.L.A. At Buchan it covers many square miles. 
Barytes. 
Very considerable quantities of barytes occur at Buchan, Mount Deddick, 
and at other sites. As it is largely used in the arts, it should become of 
economic importance when the cost of transport is reduced. 
As East Gippsland becomes more accessible, and the cost of transport 
becomes reduced, further attention will be directed to the various ores r 
rocks, and minerals that await the prospector and miner in this region.

OBSIDIAN BUTTONS. 
By E. J. Dunn , F.G.S., Director , Geological Survey. 
While at Ararat I saw in the local museum some examples of obsi¬ 
dian buttons, and was informed that they were of common occurrence at 
the south end of the range which runs to the west of the town. The end 
of the range is known as Rockv Point, and manv of these buttons are re- 
ported to have been found in the wash-dirt. Similar buttons have been 
frequently found in the auriferous wash-dirt at Mt. William. They are 
found widely dispersed in the Mallee country in the north-west of this
