20 has an average slope of nearly 30 degrees. In addition to the stripping of the ore, prospecting has been done by trenching and sinking numerous pits. The greatest thickness of limonite anywhere exposed is 15 feet; in two or three places 10 feet are exposed, and several cuts show 3 to 4 feet. In no place has the bottom of the sheet of ore been reached” eae “The ore consists of yellow and brown earthy limonite free from impurities, rather soft, and of a loose consistency” ore “The country rock on which the ore lies is an altered, greenish porphyry containing in many places, impregnations of pyrite. The writer is informed that on the mountain side above and to the north of the iron deposit are many quartz veins carrying pyrite . . . . Water is constantly flowing down the hill-side . . . . The water flowing over the iron deposit has a strong taste of iron salts . . . . plainly . . . . . . derived from the decomposition of iron sulphides farther up the mountain side. This strong solution of iron sulphates . . . . has built up the deposit er by the progressive transformation to limonite of successive layers of moss and other vegetation. . . . . (as) is borne witness by the limonite twigs, roots, chips, fir needles, and cones that have been transformed partly or wholly to limonite in the few years since the burned areas were cleared.” “An average depth of 5 feet for the deposit is almost certain; 10 feet is probable and perhaps the depth is greater. In other terms, 562,500 tons may be considered as almost certainly proven; twice that as probable and perhaps the amount is considerably larger.

A. Leverin, Mines Branch, from samples collected by J. D. MacKenzie. 1. Sample of a trench wall, from 2 to 10 feet below the surface. Taken by cutting a groove 1 foot wide, 6 inches deep, 8 feet long, and quartering to 8 pounds. 2. A picked specimen representing a 12-inch, harder, more compact band about 2 feet below the surface at the locality of No.1... 2. 3. Sample of dump thrown out of a cut. 4. Sample of dump from a trench. : “The iron ore is excellently situated for mining, provided transporta- tion could be obtained.’”! Since the property was examined by MacKenzie, the deposit has been reported upon by privately engaged engineers and in one such report it is stated that an open-cut situated near the centre of the deposit . . . . “exposed a thickness of 22 feet at present, and is said to have a shaft, now (1917) filled up, at the end which showed 8 feet more of ore without reaching bottom.” Until the thickness of the deposit has been determined at a num- ber of places any estimate of the ore content may prove misleading, but all available data corroborates the conclusion reached by MacKenzie that at least 500,000 tons of easily mined, nearly pure limonite is present and that it is not improbable that the total is considerably in excess of 1,000,000 tons. 1 MacKenzie, J.
