Rocks and Ore Occurrences. 



The association between the hornblende or with the chlorite and 

 the fibrolite does not appear to be accidental. The lode track is 

 in this rock mass, it follows the line of rock that is most 

 completely metamorphosed, and although it is well defined, its 

 filling is, apart from the mineral contents, essentially the same 

 as the country, there is a little more quartz at some places and in 

 a few others a hard chloritic " pug " impregnated with pyrites 

 and presenting slickensides is found. The metallic minerals are 

 arsenical and ordinary iron pyrites, and copper pyrites, all carry- 

 ing gold. There are very few vughs, but where these occur they 

 show crystalline quartz and calcite upon iron pyrites. The 

 copper, but not the gold contents, increase toward the line of 

 the east and west fault. 



The analysis of the rock from several different places is shown 

 in the table. Analysis (A) is of the rock adjacent to lode track 

 in No. 2 level at the Gift shaft end, whilst analysis (B), (C), (D), 

 are from samples collected along No. 5 cross cut (about 700 feet) 

 on Martin's shaft. (B) being from near to the lode track, (D) 

 from about 70 feet distance and (C) from a point intermediate 

 between (B) and (D). The rock has however large segregation 

 of oligoclase and small garnets, and no single analysis would 

 fairly indicate its composition. Analysis (E) is of the felspar 

 which is thus shown to be oliaroclase.
