of these characters and dimensions doutless could be mined at a profit if
a not too distant market were available.

On the Magnet claim the amount of ore seems large. Outcrops
belonging to what is thought to be one continuous vein, No. 3, occur over
a length of 1,300 feet and so far as can be now determined its width over
this total distance is nowhere less than 10 feet and over considerable
stretches is between 15 and 20 feet. In places the amount of ore is reduced
by a variable amount due to “horses” of country rock and to zones of ore
intermixed with a large proportion of apatite. Further cross-trenching is
needed to establish the average size and character of the vein, but at present
it seems justifiable to assume that for a length of not less than 1,000 feet
the vein will hold a minable width of 10 feet of ore. The depth to which
the vein extends cannot be foretold, but considering the visible length,
neither end having been uncovered, and its comparatively broad width, it
seems reasonably certain that the vein will persist to a depth of at least
several hundred feet, with the same average width as displayed on the
surface; it might descend to much greater depths. It is estimated that
No. 3 vein will maintain its minimum breadth for, on an average, a depth
of 150 to 200 feet and be capable of furnishing not less than 200,000 tons
of magnetite.

No. 4 vein is thought to outcrop for as great a distance as No. 3
vein, but has a proved width of 10 feet or over for a length of only 250
feet. In this distance the average breadth, making due allowances for
inclusions of country rock and zones of apatite, is not less than 15 feet, the
minimum minable contents of this part of the vein can scarcely be
less than 50,000 tons, and it is possible that a comparatively small amount
of cross-trenching would indicate that this vein is comparable in width and
length with No. 3 vein.

Nos. 1, 5, 6, and 7 veins each outcrop at only one or two places
and do not give any certain indications of being long or of width sufficient
to warrant mining, but these veins comparatively speaking are unexplored
and it is possible that systematic cross-trenching might bring to light exten-
sions of the known parts of these veins in which the ore was of considerable
width. It also is possible that at moderate depth one or more of these
veins might expand considerably.

Nos. 8, 9, and 10 veins have each been uncovered at only a single
spot and although in each case a very considerable breadth of ore has
been brought to light, there is not sufficient information available to permit
of making any reliable estimate of the value of these three veins or groups
of veins. Further cross-trenching would be required to determine if
these veins persist along the strike and their individual behaviour. Since
these three groups of veins seem to have an abnormal strike, it is possible
that the veins are also abnormal, may not continue far, and may possess
very variable widths. The veins were not sampled for the purposes of this
report, but the following assays of samples from the Magnet claim were
made by the Department of Mines, Victoria, the first sample being reported
as representing a width of 18 feet on a single vein.
