127 Magnetite veins of any considerable size, now exposed, are confined to the eastern part of the Moose claim and to the Magnet claim. The indivi- dual veins, as seen on these claims and at Glen Iron mine at Cherry bluff where conditions are essentially similar, have certain plainly developed characteristics that have a marked bearing on their economic value. Most of the veins follow courses whose directions approximate east and west. The courses of individual veins are curving and neighbouring veins are roughly parallel with one another. Most of the veins are vertical or highly inclined, but some dip at angles as low as 45 degrees. The veins do not continue inde- finitely either vertically or horizontally and examples were noted of veins terminating by gradually thinning and dying out both in an horizontal direction and in a vertical direction; in other cases veins were observed to split up into two or more veins which diverged from one another and in some cases at least, died away in a comparatively short distance. Some veins were observed to be comparatively wide over a relatively long dis- tance, others for only a comparatively small part of their observed course; other veins, so far as they were now visible, maintained throughout a relatively narrow width. It is inferred that in general the notably wide part of any vein is a local development of comparatively limited extent. In wide veins parts of them were in nearly every case characterized by the occurrence of apatite in considerable volumes, sufficient to lower the grade of the ore in a marked degree. In other cases the wide parts of veins in places carried sheet-like horses of country rock whose presence would greatly reduce the amount of minable ore. On the Signal and Anvil claims no magnetite ore of commercial value is exposed and it is thought to be improbable that any such ore occurs in the immediate vicinity of the magnetite-bearing outcrops now visible. On the Moose claim and in that vicinity, several zones of veins 1 to 2 feet broad are exposed at a few places on the unmapped north brow of the hill on which the claim is staked. These veins appear to be individually too narrow to be of value and are not closely enough spaced to permit of mining several together. They are valuable as indicating that on the Moose property conditions are such that the veins may have a considerable lateral extent. To the south of the open-cuts on this claim, two isolated outcrops not belonging to the same vein show respectively widths of 5 feet or more and 12 feet or more. These exposures may indicate the presence of several veins each 5 feet or more wide, but nothing is known regarding their possible length nor as to whether they maintain their width along the strike where the whole country side is wanting in rock exposures of any kind. In the trenches just north of these two occurrences, much magnetite is visible over a length of 200 feet, but the iron ore occurs in a zone of veins which individually thin and thicken or die away. In places several veins may coalesce and jointly expand to a thickness much greater than their combined individual thicknesses, but these expanded parts have no great length and presumably no great depth. On the other hand, either along the strike where the ground is now all drift-covered, or at some depth, some of the individually thin veins might coalesce to form a vein comparatively broad and holding its br sadth for a considerable distance. The amount of ore visible in these trenches is considerable; it may be equivalent to as much as 10 feet disposed in a number of roughly parallel veins contained in a thickness of 20 feet.
