Tin occurs in silicified and pegmatitic portions of Devonian granite, which breaks 

 through Silurian slates, sandstones, etc. Considers tin to be of pneumatolitic origin. 

 Accompanied by tourmaline, beryl, fluorspar, chlorite, argentiferous-galena, zinc 

 blende, chalcopyrite, arsenopyrite and pyrite, wolframite, and probably gold. In one 

 occurrence, considers tin in a fine grained granitic rock to be original. Some veins 

 in neighborhood carry considerable quantities of wolframite. Describes different mines 

 and gives rainfall.

Five miles from coast between Trial and Granville harbors. Geology of the district 

 described. Four kinds of veins carry SnO„ viz. : Quartz-tourmaline veins, pinitoid 

 (decomposed feldspar) veins, greisen veins, and pyritic veins. Tin occurs in nodules 

 of quartz and tourmaline, sometimes hollow, generally in aplite segregations, but 

 sometimes in the granite. Green tourmaline more apt to occur with tin than black 

 tourmaline. Much of tin in residual gravel in gray colored nuggets with granular 

 center covered by thin concentric layers, frequently layers are radiating. Residual 

 gravel 1 foot to 3 feet deep, gave 7.7 per cent cassiterite. Extent unknown. Some 

 rich veins carry up to 39 per cent tin. Tin ore spreads out from veins into sandstone, 

 parallel to bedding. 



Treats nineteen tin localities of district. Thinks region has good future.

Most of the deposits of tin ore are located in the center of the northeast Dundas 

 District. Most of the ore consists of dense iron-pyrites and pyrrhotitc, with 

 small grains of tin cxide embedded in it. Following mines are described: 



1. Penzance Tin Mining Co. 2. Mount Lyell Copper Estate Co. 3. Cornwall Tin 

 Mining Co. 4. Renison Bell Prospecting and Mining Co.
