present. In places this rock is also veined with secondary quartz. 

 Apparently the calc-chlorite schist has been produced by dynamic 

 metamorphism from a volcanic tuff or breccia, as an examination 

 Avith the microscope discloses in some of the sections the presence 

 of fragments of a rock of the nature of an andesite in which clearly 

 discernible porphyritic crystals of plagioclase felspar are preserved. 



Description of wot kings on the quartzite beds. — The largest of 

 the quartzite beds — some 20 feet in width — the outcrop of which 

 forms a prominent feature of the property, has apparently not been 

 reached by the cross-cuts extended from the shafts put down on its 

 hanging wall side by the modern workers, although there is distinct 

 evidence of an ancient working upon it. To what, depth, however, 

 the ancients were able to penetrate on this bed, I was not able to 

 ascertain as the old working is filled up. 



As far as could be seen by the small amount of development 

 work that has been done, the "veins" intersected by the cross-cuts 

 driven from the prospecting shafts consist of one or more smaller 

 beds of quartzite, lying to the north (i.e., on the hanging wall side of 

 the big bed). The correctness (or vice versa) of this view could be 

 easily determined by extending the cross-cuts some twenty or thirty 

 feet to the south, and this should be done if further developments 

 are undertaken. 



The amount of work done and the supposed position of the beds 



are shown on the sketch cross-sections which I

have drawn to illustrate this report. 



There are five shafts in all, but only three are of importance. 

 These are known as No. 3, No. 4 and " Verner's.'' , 



No. 3 shaft is down 72 feet from the top set. At 70 feet the 

 vein has been cut across. It is here about 12 feet thick. The total 

 length of drivage on the vein (including the width of the shaft) is 

 70 feet. 



No. 4 shaft is down 60 feet. From the bottom the " vein " has been 

 cross-cut. Its hanging wall is 7 feet from the side of the shaft and
