550 THE GEOLOGY OF NEWBRIDGE, NEAR BATHURST, N.S.W., 



done there. Copper pyrities occurs, as previously described, in 

 the marble at Caloola. But its chief occurrence near Newbridge 

 is at Cow Flat, where there are two lodes, worked respectively 

 by the Cow Flat Mine,* now closed, and the Belmore Mine 

 (Lloyd)t still working. The surface indications of both these 

 lodes is very distinct, being marked by haematite, malachite, and 

 a little azurite. Actinolite schist, a lime-silicate rock, is the 

 country rock, and associated are chlorite limestone and slate. 



Iron. — The iron ore deposits of Newbridge, though rather 

 small, are of excellent quality. They were described by Mr. J. 

 E. Carne, F.G.S., in 1891.; The lode runs in a north-westerly 

 direction from Portion 91 of Galbraith Parish, across Portions 104 

 and 108, where it is very poor, and appears again in the Railway 

 Reserve, and in Portion 59; it is said to have been followed some 

 miles to the north of this. A large amount of ore has been taken 

 from the outcrop in the reserve, and a typical analysis of it is 

 given in Mr. Carne's report {op. cit. p. 150). 



The southernmost opening on Portion 91 shows very good 

 specimens of haematite, sometimes stalactitic; but as a whole the 

 lode here is very siliceous. The intermediate outcrops in Portions 

 108 and 104 are useless. 



This lode is, according to Mr. Carne, " a fissure vein extending 

 for several miles, and locally thickening at the parts opened up. 

 There is yet no indication of its depth and whether or not it 

 passes into pyrites at the water-level. It is still solid haematite 

 at 35 feet deep. The walls of the lode are nearly vertical, 

 inclining slightly to the east."§ 



At Caloola in the oxidised slates that are crushed for gold, 

 there are frequent limonite pseudomorphs after perfectly 

 crystallised pyrites, which are up to one inch across. The deepest 

 workings of the gold mines, 50 feet, are still in the zone of 

 oxidation.
