KINGMAN, March 21.-More than a
quarter of century ago the Golconda
mine, in Union basin, fifteen miles
north OF Kingman, was noted for it's
production of rich gold and silver ore,
win a lead base. Following the Gus
tom then in vogue, the mine was
worked under the tribute system and
Dig money for the leasers and owners
resulted. But at a shallow depth zinc
ore, then much despised, as the smelt-
ers penalized it heavily, appeared in
ever increasing quantities until the
penalties overcome the other value, and
gradually work was abandoned. For
many years the owners held the prop
efty, only doing the annual assess
ments, until a year ago it fell under
the notice of John Boyle. jr., a man
well Yersed in handling that class of
ore.
Seeing the possibilities of mining the
exposed zinc, Mr.. Boyle secured the
property by purchase and went to min
ing for zinc alone, making by-products
of the lead. silver and gold. How well
he has succeeded is told by carload re-
sults. There was much preliminary
work to perform, such as deeper sink
ing of shafts, cross-cuts connecting the
three veins on the property, hosting
machinery to be erected and pumps to
install, tramway to be built from the
mine to the wagon road, which is two
miles from the railroad. but these were
minor troubles, soon to be overcome,
as from the very start shipping ore
was found that soon put the property
on paying basis.
Ships Sixty Cars
The mine is only developed to depth
of 24O feet in the deepest workings, yet
under the present management sixty
cars of ore have been shipped, while
as much more is on the dump awaiting
the concentrating plant which is to be
built within the next ninety days.
There is main shaft, and two aux
iliary shafts 300 feet on each side
through which development is pro-
crossing. The shipping ore is from
hfteen inches to four feet wide, while
az much more is concentrating. The
mine has recently been put into shape
so that a car every other day can be
shipped, or 45O tons monthly, averag-
ing AZ per cent zinc. The shipments
from this one mine in the year 1908
exceeded all the other zinc shipments
in the territory, and for the present
year this will be multiplied several
times. The average net value of the
ore shipped has been $3.50 car The
contract price of mining has been 81
ton, but as this has been done Will
| opening new ground, the future of the
mine, with its increased facilities. is
assured. The ore is now being shipped
company at lola, Kas.
To Mr.. Boyle is due the credit of
having been the pioneer in this field,
having shown the way to make the
mining of zinc ore profitable, for among
the diversified ores found in Mohave
county there are numerous mines where
zinc predominates.
John Boyle has taken an option on
the Tub mine from T. L. Ayres This
mine shows very large outcrop of
zinc ore, and under Mr.. Boyle's man
agement will be big producer.
Work is progressing on the German
American properties. In the Pioneer
claim, on the 1OO-foot level. is showing
very rich ore.
H. N. Waller and F. M. Townsend of
Los Angeles, who are interested in
mines on Silver creek, are inspecting
their property.
The Home-Pastime mine at Mineral
Park is about to ship another car of
rich silver ore. The last car Melted
better than 800 ton, and 1t is ex-
expected that this car will double that
in value.
