Excerpt from Mineral Resources of Canada Bulletin, 1904 The occurrence of mica in large and important deposits, at several points in eastern Canada, was recognized by the officers of the Geological Survey, almost from the commencement of the study of the crystalline rocks, and several references to this mineral are found in the earliest reports of the department. The true economic value of the mica deposits was not however ascertained until a comparatively recent date. Its intimate association with apatite at many places was disclosed during the working of the latter deposits many years ago, but down to within the last fifteen years the mica was regarded practically of but small importance, and the quantity necessarily extracted in the removal of the apatite was thrown out on the dump. Around many of the old apatite mines, even at the present day, large quantities of this mineral, now rendered useless from long exposure to the weather, can be seen. Generally speaking it may be said that mica came into marked prominence owing to the discovery of its fitness as an adjunct in the manufacture of dynamos and other electrical appliances, and as a consequence not only were many of the old mines, which were worked for apatite up to the decline of the market for that mineral some years ago, and in which mica was known to occur in considerable quantity, reopened, but its presence was soon ascertained in other portions of the crystalline rocks which had hitherto been unexplored. Many of the properties thus taken up as probably mica-bearing were soon abandoned, owing doubtless to the limited extent of the deposits in some cases, or to the inferior quality of the mica in others, but some of these have been developed into large and profitable mines which have been worked almost continuously for many years. Practically, at the present time, all the mica mining in Canada is confined to the provinces of Ontario and Quebec, with the exception of an, area found in the Rocky mountains near Tete Jaune Cache, B.
