MINING DISTRICTS OF LOWER rfiflAK. 3 



At Klian Gimong ( Kampar ) the limestone is again visible, 

 being white crystalline and containing, in numerous fissures, the 

 tin-ore that has drifted from the granitic formation in the vici- 

 nity. 



South of Gropeng, between Kampar river and Bujang Malacca, 

 several high hills — Grimong Eamian, Gajah and Kandong — are 

 entirely of limestone, and resemble, on a larger scale, the well 

 known Gimong Pondok near Gapis and Gimong Kurau. 



In other spots, such as Kampong Baru on Sungei Kampar, 

 the limestone does not seem to have been much altered by the 

 contact of the Bujang Malacca group, and has kept the usual 

 aspect of mountainous limestone. 



In the Batang Padang district, South of Tapa, the sedi- cimj. 

 mentary formation is represented by white clay imbedding 

 nodules of red ferruginous matter. 



In a few places of the same district talc-schist can be seen Taic-Schisi 

 cropping out from under the clay and resting on decomposed 

 granite. 



In this particular mining district the tin- ore is found at the 

 very top of the hills, which leads one to infer that the upheav- 

 al which has produced them must belong to a second series 

 of plutonic action posterior to that which has formed the prin- 

 cipal ranges of the country. 



TJlu Kinta district, which includes most of the region above ^MINING! 



° DISTRlCTo, 



Pengkalen Pegu ( see Map ), is the most extensive of all, but uiu Kinta. 

 at the same time, owing to the greater distance from the sea, 

 is the least worked by miners, who naturally prefer turning 

 first to account the mineral wealth of the lower country. 



It is a " reserve " for the future, and will, no doubt, be found 

 just as rich as any other part of the State. 



At present the principal works are carried on on the Sungei 

 Pari and Sungei Chemer, at the foot of the Senggan range. 

 The tin-ore produced is of a very good quality, and contains a 

 large proportion of white oxide. 



The Sungei Kinta itself contains considerable quantities of
