TIN MINING IN PERAK. 29 



A second made at another time of the produce of the 

 same mine gave : — 



Fine gold 80-00 



Silver 2000 



100-00 



Taking the mean of these two determinations or 791 fine, 

 which is almost nineteen carats, the gold value of this lode 

 bullion would be ^£3 7s. 2cl. per Troy ounce. 



A sample of the alluvial gold dust, as it is cleaned for sale 

 by the Chinese miners from a mine at Sungei Jong near Tapah, 

 gave these results on assay : — 



100-00 



This gives the proportion of the two precious metal as : — 



Fine gold 94-Gl 



Silver 5-39 



100-00 



This may be taken as a fair example of the Bataug Padang 

 alluval gold dust, both as regards its composition and its ad- 

 mixture of impurities. The dust would be worth =£3 19s. 4d. 

 per ounce, and when melted £4 Os. M. The latter would be 

 22f carat gold. This sample of gold dust was bought in Tapah 

 recently for §40 per tahil, which at 2s. 2d. per dollar (the then 

 rate of exchange) would equal a sterling price of .£3 lis. dd. 

 per ounce, Troy. 



Other ])arcels of gold dust from Batang Padang have given 

 the under mentioned results on smelting : — 



Weight of gold dust ... 6,310 

 Weight of smelted gold 5,927 



Loss ... 383 equal to 6-06 per cent.
