PAGAYE MINK. 283 



partnership basis. In August 191G this was transferred to the 

 Bombay Burma Trading Corporation, Ltd., who still hold an option 

 to purchase it. The Rangoon .Mining Co. has an authorised capital 

 of Es. 3,50,000, of which Rs. 2.10,000 are issued. 



The main mineralised zone, or. as it is known on the mine, the 

 ' ; A " : svstem. has a known strike extension of over 3,000 feet and 

 its limits have not been determined. It runs in a north 38° westerly 

 direction. Parallel to it and some 500 feet away on the south ride 

 of the stream there is another zone, while a third series cuts across 

 the first one striking north 38° easterly. The general vein strike within 

 the first two /ones is 42° west of north and east of south and the 

 dip 80° to the north-east. The cross veins strike 38° east of north, 

 west of south and dip at 80° to the north-west. The exact strike 

 of any one particular vein is impossible to determine because the 

 svstem consists of a mass of veins which coalesce and branch in 

 all directions. These are the remarkable Pagayc pegmatites whose 

 mineralogical features have been described in another chapter. 

 According to .Mr. A. II. Morgan, the General Mining Manager of 

 the Corporation, to whom we are indebted for much information, 

 variations in the strike are due to these divergencies, and actual 

 measurements give in an extreme case a strike 17° west of north 

 and others between this extreme and the mean. Mr. Morgan 

 points out that the cross veins are more constant in width and 

 bearing, that they appeal to have been formed simultaneously 

 with the main veins and that no differences are observable at the 

 intersections. " The wolfram and tin-stone are unevenly distri- 

 buted throughout the veins and the richer patches may be termed 

 ore shoots, but they are not absolutely isolated as there are usually 

 specks or small bunches of ore in between." It now appears certain 

 that the Pagaye pegmatites come to the surface as we know it, 

 split up into almost innumerable ' stringers which are often extremely 

 rich— sometimes solid wolfram or cassiterite or both. Scheelite 

 also occurs in them and the edges are always bordered with mica. 

 As they descend through the argillites they coalesce and widen. 

 In the hard rock of the lowest workings they broaden out to (i feet 

 and seem to promise still greater widths at lower depths. Felspar 

 appears in greater quantity with depth and very often there is a 

 peculiar banded arrangement with the felspar on the sides of the 

 vein and the quartz in the middle, as contrasted with the more 

 usual chessboard pattern.
