pecting in the mountainous portion of the Grant has been
carried on to a very limited extent. Gold mines, however,
are worked on and Grey Back Gulch, and an iron
mine called "Placer Iron Mine", of great prospective value,
has been worked, for which a royalty of 25 cents per ton was
paid to the Grant owners by the Colorado Coal and Iron Com-
pany. 11,862 tons of iron ore have been mined. The fol-
lowing is an average analysis of this ore, which at once
shows it to be one of excellent quality.

A spur from the D. & R. G. R'd. reaches the mine in
a distance of 2 1/10 miles. It is not at present in opera-
tion because the C. C. & I. Co. has acquired iron mines of
its own, and is not at present getting its supply from this
source.
The gold placer grounds are situated in the north-
eastern portion of the property and are very similar to those
on the Maxwell Estate, which property adjoins the southern
portion of the Sangre de Cristo Grant on the east. These
placers would undoubtedly have been extensively worked had
