think that ov/ing to the mass of data necessary, before a mill is
erected that this should bo collected as early as possible•

* HEAVY PYRITE VEINS; There is a considerable tonnage of milling
grade oro in the mine and in the"George E" workings on the west
side of the creek. This class of ore might be mixed with the heavy
lead ore but most careful experimentation should be carried out
before hand as it is often found in flotation that the presence,
in one ore or the absence of another of some chemical constituent
totally alters tho recovery. These heavy pyrite ores can make a
profit if thoy have to be milled separatly, however, but at present
with the higher grade ores in sight they make a splendid reserve,
and, if continous, would yield 9,500 tons of $14.00 per ton.
5" HIGH SILVER ORES; Ores of this class are encountered in the
north droft of #3 tunnel and on the "Sunbeam" claim. While much
of tho "Sunbeam" oro shows every indication at present of being in
the direct shipping class, yet it may bo necessary to mill portions
of tho deposists. There is every liklihood that the tailings from
the flotation machines will have to bo cyanided owing to the heavy sh
showing of native silver* The galena and blonde, however, appear
t.o bo clean and should present no obstacles to milling, There is
some arsenic present on the "Sunbeam" but the quantities I have
encountered so far are not sufficient to bo detrimental*
The values in the north faco of • #3tunnel are
considerably higher than further back the levol, and the galena,
while not heavy, is however, heavier than further back- further
exploration ho^e is most necessary to provo the extent of this stopping
up in values,. Tho average of the whole levol ovor 6 feet is
0 per
ton*
