The same pegmatitic granite (largely an andesine rock) is shown 

 here but the country rock is the sedimentary amphibolite, dipping 20° 

 to 22° south 20° west (magnetic). The east wall is pegmatite and, 

 as far as the section shown in the pit is concerned, can be regarded 

 as a vertical plug which has sent dikes and stringers of its own 

 material westward into the amphibolite, producing large flake 

 graphite on contact. Much of the ore taken from the Young Lion 

 pit is pure white pyroxene, in which flakes of graphite one-fourth 

 of an inch in diameter are promiscuously distributed. The far end 

 of the pit is filled with water. It is understood that the long drift 

 at the " Woodchuck " workings was begun in an attempt to tap this 

 to furnish drainage, but the enterprise was poorly planned inasmuch 

 as they would have failed to make connections if the initial direction 

 had been maintained. Along the line of contact w T ith the main 

 mass of pegmatite and the amphibolite the miners have removed a 

 large amount of ore by stoping, reaching to the surface in several 

 places. 



The Old Lion tunnel. About half way between the " Wood- 

 chuck " and the " Young Lion " pits is a portal to a drift that is 

 said to connect with the Young Lion pit. 



The higher workings. Higher up and above the Young Lion pit 

 are a series of workings, side wall pockets, trenches etc. They 

 reveal examples of the same type of contact — the pegmatite upon 

 the amphibolite. 



The Fryatt workings. These are located a little to the east of 

 the Young Lion pit, north of the old wood road, consisting of open 

 pits verging on drift openings on two distinct levels. The upper 

 series consist of two wall pockets, from one of which an inclined 

 tunnel leads to the lower level to the west. The workings on the 

 lower level comprise two wall pockets driven some 6 to 8 feet into 

 the north wall. A drainage trench leads south. At the west 

 end of the main pit a drift has been driven westward, rather near the 

 surface, for in places this has fallen in. 



The geology here presents a third species of contact deposit. 

 Here the ore is the green augite-scapolite (the latter mineral, is 

 chiefly meionite 1 ) rock. Closely associated with the contact rock 

 is a quartzose material that may be either recrystallized quartzite or 

 true vein matter. It is analogous to the crystallized calcite in the 



Bastin, E. S., Economic Geology, 5:147-48.
