65 interest is . . . . (the) Iron Crown . . . An exposure of mag- netite extends along the face of the river bank for some 180 feet. The height of the bank is about 80 or 100 feet, forming at some points cliffs of magnetite 25 to 30 feet high. . . . Farther up the hill, about 650 feet from the river, several outcrops of magnetite occur along the ridge. The solid formation being effectively covered’ by a sandy loam and a heavy vegetation, the outcrops mentioned were all that could be seen. . . . (The results of a magnetometric survey combined with the distribution of the observed outcrops indicate in the case of the mag- netite occurrence along the river bank that the width of the body) at the west end may be estimated at not less than 100 feet. The length may be assumed to be about 190 feet. . . . (The deposits outcropping along the ridge, back from the river, are) the most important and may be assumed to consist of two, possibly three, ore lenses. . . . (The largest) Pan has a length of at least 380 feet; a width of 60 feet is very probable, and in some places, it is even greater. . . . (The existence of a third group of ore-bodies, lying on the slope below the last mentioned, is indicated by the magnetometric survey, but this mass) is altogether covered by soil. The magnetic curves show . . . . the ore strike to be about parallel with the former group, with a length of about 480 feet, and a width which, in places, may be assumed to be very little less than (60 feet). . . . As far as surface indications go, the claim may be said to be one of the best iron prospects on Vancouver island.” On the map accompanying the report by Lindeman, magnetite ore is indicated as outcropping within 100 feet of the river, in three places in a length of 150 feet along an east direction. The second group of out- crops, according to the map, lie 500 feet south-southwest of those closer to the river, and consist of cight individual outcrops, distributed over a length of 380 feet trending southeast, and a breadth of 100 feet. The district is known to be at least partly occupied by an assemblage of volcanic and sedimentary rocks, including limestone, that are invaded by large and small bodies of granite, granodiorite, etc. Though Mr. Lindeman’s report makes no further reference to the mineralogical com- position of the ote than as given in the above excerpts and makes no reference to the rocks displayed anywhere in the general vicinity of the claim, it is highly probable, if not almost certain, that the magnetite deposits of the Iron Crown claim are of the contact-metamorphic type so widespread along the Pacific coast. That is, they are presumably replace- ments of volcanics or of sediments or of both kinds of rock. The masses probably vary from nearly pure magnetite to low-grade mixtures of various silicates. It is possible that the few outcrops are a measure of the amount of ore (as distinguished from low-grade mixtures of silicates and magne- tite) present, because the masses of more nearly pure magnetite are more resistant to weathering than the mixtures of magnetite and silicates and, therefore, tend to stand out in relief on the rock surface and, consequently, tend to form most of the exposures in drift-covered areas. No reliable estimate of the amount of ore present can be formed from the available information. If only half of each of the mineralized areas outlined by the magnetometric survey are composed of iron ore as dis- tinguished from low-grade mixtures of magnetite, silicates, and country rock, then the amount of ore present would, in all probability, be at least 100,000 tons and the total might be much greater.
