70 GEOLOGY AND MINERAL RESOURCES OF SIKHIM. 



7. Barmiak. — Near Barmiak, just south of the new bridge over 

 the Tista at a place called Lingyathang, I found on the east bank of 

 the Tista, traces of copper ore in some detached blocks of quartzite. 



There is also copper ore near the head of a stream south of 

 Barmiak, called Kalok jhora. 



8. Namphak. — There were found minute traces of copper pyrites 

 in a detached block at this village, close to the Tumlong road between 

 it and the Tista. 



9. Dajong. — Close to the head of the Rangpochu, about 3 

 miles north-west of Yangong monastery, steep scarps of the Dalings 

 are seen from a distance to be stained green by carbonate of copper 

 at places. The place is almost inaccessible, and I could not explore it 

 well within the time at my disposal. At one spot about a mile-and-a- 

 half east of Dajong there were met with chalco-pyrite along with 

 peach and iron pyrites in some profusion in quartzitic rocks. The per- 

 centage of copper, however, appears to be too low to pay for working. 



10. Temi. — About three miles west-north-west of this village, 

 close to the source of a stream called Rimpichu, there was found 

 copper pyrites in some abundance in very hard quartzitic rocks. 



Trial pits were opened both here and at Dajong last year by a 

 Nepalese named Parsa Sing, but have been abandoned. 



11. Tukkhani. — These mines are situated along a feeder of the 

 Mangpur jhora, a tributary of the Rungeet, three miles due south of 

 Namchi. They were deserted some time ago owing to the excava- 

 tions filling in with water. The ore is said to have been of excellent 

 quality, better even than that of Pachikhani, though now but little is 

 seen of it, the galleries having fallen in. Deep mining here would, I 

 have no doubt, give good results. The annual outturn of Tukkhani 

 used to be about the same as that of Pachikhani — about 450 maunds. 

 The lessee was Luchraidas. The country rock is slaty shales 

 similar to those of Pachikhani. 



12. 3Iik. — Two miles north-east of Tukkhani, close to the 

 village of Mik, just by the Namchi road, cojDper pyrites were found 

 disseminated in some very hard quartzites. 



13. Monghru. — A mile north-east of this village, and about three 

 miles south-south-west of Ralong monastery, close to the junction of 

 a stream flowing from Rabongla with the Rungeet, there occur copper 

 pyrites in clay slates with segregated quartz. 



14. Rinchinpong. — Copper ores occur near this place, close to the 

 source of a feeder of the Kulhait. The rock as usual is clay slate. 

 The ores were worked on a small scale last year, but have been given 

 up, as they did not pay. 



15. Bam. — Two miles and-a-half south-south-west of Rinchinpong 

 monastery, close to the village of Bam, there occur, by the Risi, copper
