25 DESCRIPTION OF THE ORE OCCURRENCES At several places on the jutting point southeast of Stuart anchorage, magnetite occurs in small quantity impregnating parts of bands of micaceous schist, but only in one place does any important amount appear at the surface. At this place a band of mica schist possibly 150 to 250 feet broad forms a narrow ridge which strikes southeast at right angles to the shore and rises along its axis to a height of 100 fect in a distance of 200 feet from the sea. The ridge is largely covered with drift, but rock is exposed at its base at its shore end and over an area a few feet wide and 150 feet long extending from the shore along the northeast side of and close to the axis of the ridge. Several shallow trenches extend from the long rock exposure across the axis of the ridge and two other trenches, respectively 60 and 135 feet distant from the southeast end of the long rock outcrop, cross the strike of the strata. Farther southeast along the ridge a few rock exposures are present. The magnetite outcrops in several masses at the water edge at the northwest end of the ridge, and is exposed in a band not averaging more than 4 feet in width and which for a length of 200 feet is visible in the long exposure on the northeast face of the hill. Sixty feet southeast of the end of this band of ore and along its strike, no magnetite is visible in a crosscutting trench. Seventy-five feet farther southeast, a second trench shows schist impregnated with magnetite over a width of several feet. In the case of the several smaller masses of magnetite at the seaward end of the ridge and the long, band-like area, on the northeast slope, although one boundary may be sharply defined, the other usually is not so and for a space of one or more feet the bordering schist is rich in magnetite, or bands of schist and magnetite-rich schist may alternate. The several small bodies at the shore end of the ridge range in length from 15 to 30 feet, and in each case end to the southeast rather abruptly and, possibly, against a fault-plane, though no direct evidence of the existence of a fault was noted. The purer magnetite is compact, fine-grained, with some admixed biotite and other mineral constituents of the schists. MODE OF ORIGIN The occurrence of the magnetite in bed-like masses associated with schists of, presumably, sedimentary origin, may suggest that the magnetite also is of sedimentary origin. The sporadic appearance of magnetite elsewhere in the general vicinity and the numerous examples along the Pacific coast of magnetite bodies associated in origin with plutonic rocks, gives rise to the presumption that the magnetite occurrences on the Royal claim also are secondary, and are of the nature of replacement bodies formed along lines of weakness in the more schistose members of the sedimentary series. ECONOMIC CONSIDERATIONS The band-like body of magnetite outcropping on the northeast. side of the ridge is exposed over a length of 200 feet. At its northwest end it passes below sea-level. At the southeast end it disappears beneath drift. Sixty feet beyond the southeast end, a cross-trench fails to reveal ore; either the band ends in this distance or it has been displaced by a fault.
