ounces of silver, 20,957 ,404 pounds of
lead, 1,S03,423 pounds of copper, and
72,493,17S pounds of zinc, with total
value of $13,S39,4 ,4o1 in 1915. The sew
eral ambitious drainage operations by
pumping already have resulted in ship
ments of manganese-silver ore from
the downtown district, and of zinc car
Donate from the Fryer Hill district,
and the Carbonate hill drainage will
unwater zinc sulphide ores already
partly developed. The output of zinc
carbonate was 100000 tons of 21.5 per
cent, against S2,592 tons OF 22.48 per
cent in 1915. The zinc sulphide smelt-
ing and concentrating ore was $4,000
tons of 21 per cent, as compared with
1866 tons of 22.09 per cent in 1915.
The Derry Ranch dredge, below Malta,
continued operations during the year.
The San Juan region of Dolores, La
Plata, Ouray, San Juan and San Mig
uel counties, produced $3,0O0,000 in
900 pounds of lead, 100000 pounds of
copper, and 100000 pounds of zinc,
valued in all at $4,000. 900, against 49,.

pounds of copper and 1,3S2,334 pounds
Of zinc, having a total value of $6,210,-
494 in 1915. San Miguel county main
tanned its yield of over s2,000,OO0 gold
and 100000 ounces of silver; the
yield of lead in Dolores county in
creased but the output of the other
metals decreased. San Juan county
produced less gold but made gains in
the yield of all the other metals. La
Plata county's gold and silver yield
decreased considerably. The heaviest
decrease (s722,000 for gold, 10000
ounces of silver and $4,000 pounds of
copper naturally was shown in Ouray
county, where the Camp Bird mine
and mill were closed down in August
to await the completion of the low
level adit 10,700 feet long. which will
cut the Camp Bird 45O feet below the
present deepest workings and 500 feet
below workings of the next most i'm
portant section. The adit has been
driven several thousand feet in 1916.
but will not be completed for twenty
seven months from the time work on
it was begun. The Wanakah copper
mating plant at Ouray, active in 1915,
was idle in 1916.
Boulder, Gilpin and Clear Creek
counties produced s1,OOO,OoO in gold,
$4,000 ounces of silver, 5,500,0OO
pounds of lead, 100000 pounds
OF copper. and 100000 pounds
of zinc, as compared with sl,2i9,S94 in
gold, 790.065 ounces of silver, i,00S,744
pounds OF lead. 1,094,012 pounds of
copper, and 1.516,o32 pounds of zinc in
1915. Boulder county maintained its
1915 yield except for gold, there being
decrease of $4,000 for that metal.
ais increased somewhat. and Gilpin
county maintained its 1915 yield.
Chaffee county's gold. silver and
lead output fell off, but its copper and
zinc yield increased. The Pitkin coun-
ty (Aspen) yield was $4,000 ounces
of silver. and 16.6oo.oO0 pounds OF
lead. an increase of 1000 ounces of
silver, but decrease of 2,70000O
pounds OF lead.
The yield OF Creede (Mineral coun-
ty) showed improvement over 1915. as
did also Gunnison and Hinsdale coun-
ties
Summit county's production was
sG6O,OOO in gold. 100000 ounces OF sill
ver 100000 pounds of lead. $4,000
pounds of copper, and 10000 pounds of
zinc, as compared with s6s0,144 in
gold, 64,223 ounces OF silver, 1,916,29S
pounds of lead, and S,597,4l1 pounds
of zinc in 1915. The four dredges at
Breckenridge produced about the same
output as in 1915, and the shipments
of zinc from Breckenridge increased
heavily. There was a revival of min
ing at Kokomo, Robinson and Monte
yuma.
Eagle county made the largest out
put since mining began at Red Cliff,
in 1879. The output of zinc was 80,
O0O,O 900 pounds, as against 11,141,750
pounds in 1915. The Eagle NJ. & NJ.
Co.'S magnetic separation wet concen-
traticn mill was actively operated on
ore from the Iron Mask mine, and
large quantities OF zinc-lead ores were
shipped from the Black Iron mine. The
Brush creek silver district was also
active again.
Lode mines in Park county made an
appreciably increased output, particu-
larly of gold, but the placer output de
creased somewhat. The London mine,
at the head of Mosquito creek. was the
principal producing property.
Custer county mines were more ac.
tive than they mad been for several
years, and with the commencement OF
