209 ECONOMIC CONSIDERATIONS Extent of Deposit __ The outcrops of magnetite, and magnetite mixed with rock, occur at intervals through a northwest-southeast distance of 700 feet, and are separated from each other by areas of drift from 20 to 280 feet in width. The outcrops occur throughout a vertical range of 150 feet. Little may be said of the extent of the mineralization beyond these limits, since the country is covered by glacial drift and timber; but in estimating the possible extent of the various bodies of magnetite examined, the following topographic fact was made use of, namely, that where solid bodies of magnetite were cut by the present topography, they were found to stand somewhat in relief above the general slope, as a hummock or a bump. Such relief features were not observed along the continuation of the line of magnetite exposures in this claim. However, it is not fair to assume that all the individual or separated bodies of magnetite on the claim should extend upwards to the surface. Development One tunnel, 125 feet long, with a side drift 50 feet long from it, three open-cuts, and several strippings are all the development seen on the claim at the present time. Analyses The following analyses seem to give a fair idea of the grade of the deposit: — A B Cc D E FE G H J One eee ect 35°33 53-49 24-77 37-64 26-97 48-4 48- 56:6 55-6 Phosphorus. 0-020/ 0-006) 0-031) 0-020) 0-020) trace : nil | trace Manganese 0-20 Silica... 19-86 Insoluble. . 8-98 Sulphur...

These samples, taken by both government and private mining engineers, reveal a wide variation in the grade of the ore from a very rocky, impure grade to fairly solid magnetite. Very little of the material represented by the above analyses could be shipped without beneficiation. Tonnage Estimate It is impossible with the available data to make any estimate of reserves, proved, probable, or possible.
