120 COGGIN BROWN : MINES & MINERAL RESOURCES OF YUNNAN. 



Other Occurrences in the Meng-hua T'ing district. 



An abandoned copper mine is stated fco exist at ffua-pang to 

 the north-west of Ta-tsang-kai, 



Copper is said to be mined and smelted near Kung-lang, a large 

 village on the northern side oi the Mekong aboul liall way between 

 Meng-hua Ting and Fun Chou. (Lat. 24 30'; long. 100° 10'). 



Sha-ho ch'ang copper mine near Yung ch'ang Fu. (Lat. 25" 6': 



long, 99 10'). 



Sha-ho-ch'ang lies about L5 miles to t lie north-north-west of 

 Yung-ch ? ang Fu, as the crow flies, It is best reached by I he 

 northern route which skirts the edge <>l the Yung-ch'ang Fu plain, 

 and loads across the Salween-Mekong divide into the valley of the 

 Salween. The mine is in the narrow valley of a small tributary 

 of this river. The divide attains a height of aboul 0.000 feet. 

 After leaving the alluvium of the plain a series of ancient greenish 

 slates, clay schists and phyllites is met with, extending to the imme- 

 diate vicinity of the mine. Here hard reddish sandstones are 

 found, striking west-north-west to east-south-east. They are intruded 

 by a very altered basic rock. 



Ancient slag heaps of considerable extent occur in the neighbour- 

 hood and the mine is said to have been in a very flourishing condi- 

 t ion about 20 years ago. It is not apparent why operations were 

 stopped, but in L909 at the time i^ my visit re-opening was taking 

 place under the patronage of the local Chinese authorities in Yung- 

 ch'ang Fu. The new work had only commenced a lew weeks 

 before my arrival, but at that time over 70 men were employed 

 and metallic copper was being made. 



The workings were, all in the steep hill-side to the east of the 

 village. There were indications of numerous old workings, while 

 tour or five places were being opened up. hut did not extend for 

 any distance. In one adit I noticed a quartz vein from 5 to <) 

 inches in thickness containing abundant ehalcopyrite. The diabasic 

 country rock on both walls was impregnated with the same mineral. 

 In the other workings, similar impregnated ore was seen. Near the 

 surface oxidation had taken place with the formation of copper 

 carbonates. 



After mining the ores are handpicked. and the poorer material 

 freed from gangue by crushing and washing. After a preliminary
