WOLFRAM FROM BATANG PADANG. 77 
A lot, about 60 per cent tungstic acid : 
10s. gd. per unit per cent of tungstic acid, or about £32 per ton, 
at the mine. 
A lot of 3 tons, about 50 per cent tungstic acid: 
8s. per unit per cent of tungstic acid, or £20 per ton, at the mine. 
These particulars, I trust, will be of service to the Colonial Govern- 
ment in coming to a decision as to the practicability or otherwise of 
working the deposit at the Straits Settlements. 
It appears to me, seeing that the ore at Perak is considerably richer 
in tungstic acid than any quoted above, it would be well worth while to 
work the mine.

The samples reported on above were collected at Chumor, near 
Tapah, where wolfram occurs in considerable quantity mixed ratli the 
alluvial tin. The Chinese miners pick it out by hand from the tin-sand 
and throw it away, but an appreciable amount remains, and must lead 
to a not insignificant loss of tin in the smelting. 
Recently the ore has been collected and sent to Europe. The 
following return gives the export from Batang Padang up to July, 
1894 :—

Veins of quartz containing wolfram have been noticed at Chumor 
traversing the greiss-stone—a variety of granite composed of quartz and 
mica—which is rather extensively represented there. 
Wolfram has also been found in granite at Jenah, near Taiping, and 
near Tambun in Kinta, in the limestone formation. 
Scheelite, another ore of tungsten, has been found, associated with 
alluvial tin, at Plang, in the district of Kuala Kangsar, and at Lahat in 
Kinta. This mineral is a tungstate of lime, and contains from 76 to 80 
per cent of tungstic acid, from 18 to 1g per cent of lime, and sometimes 
one or two per cent of silica and peroxide of iron. A sample from Plang 
gave, on assay,—tungstic acid, 76°50 per cent. This would equal 61°20 
per cent of metallic tungsten. At ris. per unit of tungstic acid this 
scheelite would be worth £42 1s. 6d. per ton, or about $21 per pikul.
