220 SILVER LOCATIONS OF THUNDER BAY. 



angular portions of the country-rock, in places much altered by chemical 

 action, being thickly interspersed amongst the gangue. In some places, 

 these imbedded portions of rock are of comparatively large size, forming 

 the so-called " horses " of the miners. Here and there, the minute 

 cracks, by which they are traversed, are coated with native silver and 

 foliated silver glance. In the veinstone proper, especially near the 

 south or foot wall, both native silver and silver glance occur throughout 

 the entire depth to which the main shaft has been at present sunk (67 

 feet) ; and some rich pieces of ore have been taken from near the 

 centre of the .vein at various depths. The vein carries also black and 

 yellow zinc blende, specks of galena and copper pyrites, iron pyrites, 

 arsenical pyrites, crystals of colorless, smoky, and amethystine quartz, 

 and cubes of pale green fluor spar. The yellow blende holds in most 

 samples a small amount of silver j and, in one assay, a trace of gold, 

 corresponding to about 2 dwts. in the ton, was obtained from it. 



Several cross lodes intersect or run into the main lode. These are 

 at present altogether undeveloped, but they shew on the surface a 

 gangue of quartz carrying small quantities of galena, blende, and 

 pyrites. One enters the main lode on lot 9, and runs S. 78° to 80° E. 

 Another, on lot 8, runs towards the N.E., and re-appears apparently 

 on the east bank of Current River. These cross veins exhibit an 

 average breadth of from five to seven feet, and, as they are well defined, 

 a certain outlay might be legitimately expended on their development. 

 As the expense of sinking upon them, however, would be considerable, 

 it would be advisable to wait until the drifts upon the main lode reveal 

 their comparative richness at the points of intersection. A shaft was 

 commenced in the Autumn of 1867 on the main lode, on the dividing 

 line of lots 8 and 9, but as this shaft was not well proportioned, it was 

 stopped at a depth of about six fathoms, and another was commenced 

 at a distance of 175 feet to the west, on lot 9. This has been carried 

 down to a depth of 67 feet, but the work is now suspended. From 

 the conformation of the surrounding district, there Would appear to be 

 little apprehension of trouble from water in continuing the shaft, but 

 in case of any difficulty of this kind, an adit might easily be driven on 

 ^he north side of the lode so as to drain all the Workings above the 

 level of 120 or 130 feet, measured from the surface outcrop of the 

 vein. 



Many exceedingly rich peices of veinstone have been taken from 

 both the main and eastern shaft, but it is not, of course, pretended that 

 the vein, as at present developed, will yield pay-ore throghout its width,
