COPPER. 70 



is no high ground near, so that it must be worked below the level of 

 the stream, and in such slates the influx o£ water would undoubtedly 

 be very great. 



Copper is said to exist near Chamurchi in Bhutan, and several 

 years ago, as I was fold by the headman of the 

 place, some Nepalis made a commencement of 

 working it, but were driven away by sickness. The headman did not 

 know the exact locality, but said it was a short way up the river from 

 his village. I found a piece of quartzite in the bed of the stream 

 containing copper and iron pyrites disseminated through it. 



About half a mile west of Baxa there is a spot on the hill-side 



where copper has been found, but not worked. 



The rock is greenish slate with quartzose layers, 



the latter especially containing mundic with some copper pyrites, and 



the surface debris at the spot is cemented into a gossany breccia. The 



proportion of mundie is greater than that of ore. 



Mr. Beckett, when Deputy Commissioner of Jalpigori, gave per- 

 mission to some Nepalis to work copper ore near Baxa, but I have no 

 information as to whether they actually did so.
