| The writer is quite certain that these analyses do not represent the
average grade of the entire lode, which would of necessity be lower in
iron and higher in insoluble constituents, but it is interesting to note
from these figures that the magnetite is free of titanium, and well below
the Bessemer limit in sulphur and phosphorus. It is a fact that the
inclusion of masses of gangue, as would be the case in the mining of the
deposit, would quite noticeably augment the sulphur content, but not
the percentage of phosphorus. It should also be noted, that samples
taken from near the surface would likely have undergone sufficient leaching
to lower to some degree their sulphur content.

Development

Nature has done more to develop this deposit than has man. Bugaboo
creek, by its erosive power, cut through the blanket deposit and exposed
its bottom; and developed a vertical showing of 40 feet within the canyon.
A tunnel, 14 feet long, in solid magnetite, driven from a point 8 feet above
water-level, and the two old open-cuts referred to are the only openings
made by man that the deposit shows today.

Tonnage Estimate

With the small amount of development that has been accomplished
on this deposit, it is scarcely safe to attempt to estimate tonnage of ore;
but in order to make the size of this deposit to some degree concrete,
the accompanying figures are offered, and the data are given on which
they are based.

Proved Ore: Ore contained within the boundaries of the exposures, to a
depth of 64 feet in the “‘tails’’ and an average depth of 20 feet in the main
mass (at 8 cub. ft. per ton) = 8,000 tons.

Probable Ore: Ore that represents an extension of 25 feet lengthwise
and downward beyond the boundaries of the block included as proved ore
(at 8 cub. ft. per ton) = 16,000 tons.

Possible Ore: There is not sufficient data available to permit of any
worth-while estimate of possible ore.

Value of Conqueror Deposit

This deposit is too small to be of any commercial value by itself, but
it should be considered in its relation to the value of the group of magnetite
deposits along Bugaboo creek.
