Notes on the Non-Metallic Minerals of the Lillooet District

That the construction of the Pacific Great Eastern railway has not been accompanied by an immediate and great development of traffic is not due to lack of natural resources in the district traversed, but to conditions that have delayed their development. Prior to the commencement of construction of the railway there was no inducement to prospect for any other mineral than gold, on account of lack of transportation. The war began soon after the commencement of construction; diverting practically all capital that might have been available for opening up the country; and since the war, capital has continued shy of new investments. If the war had not occurred it is probable that prospecting and development would have been carried out concurrently with the railway construction. Moreover, much of the district is covered deeply with drift, marine and alluvial deposits, rendering prospecting for lode mines a more expensive and slower proceeding than can generally be undertaken by the ordinary prospector, without capital. On the other hand, the presence of large porphyry dykes, granitic intrusions, and the finding of rich float in places are indications that rich miIY.ral deposits probably exist in several localities in the Lillooet district, in the Cariboo proper, and also nearer the coast. Two or three mines producing the tonnage of the? Britannia would materially alter the earnings of the railway and pay interest on the bonds. There are, however, other possibilities, in addition to large metaliferous mines, in the non-metallic minerals of the district.
