We understand that nearly half the
men who are employed at the Plumas

water to furnish power for the ma

water in that country has given out

mill on the property and the ore is said
to pay well. When the vein is further
developed a larger mill will undoubt-

We are reliably informed that new

Active Allegheny
Allegheny has become the animating
center or hub of gold mining activ-
1ty extending over a considerable area,
down Kanaka creek for five miles to
SCOTS Flat, to Mountain House and
Brush creek on the northwest, Oregon
creek, Forest City and Rock creek on
the north. six miles to the east to
American HILL and to Moores Flat four
miles to the south. the latter camp be-
ing in Nevada county Development
and exploration in the past year have
wfdened out the auriferous zone to the
east and west. 1t Is approximately IL
miles wide.
Allegheny was the mecca last year
for mining men from all parts of the
United States. All expressed surprise
that camp and district SO richly en-
dowed could have remained in obscur-
ity for half century. The natural
advantages, iacluding abundance of
timber and water, with so salubrious a
climate, caused Allegheny to appeal to
them as the miners IDEAL.
The greatest and most important feat
of mine engineering in the history of
Allegheny gold lode mining was
achieved June ], 1910, when the cross
cut tunnel in the Tightner mine inter
daylight at a point 100 feet verti-
cally below the summit of the Allie
ghany ridge. The tunnel had been
four years in driving, and it was a
tacit and generally agreed understand
ing by all those interested in the camp
that with the success of the tunnel
hinged the permanence and future of
get values at the lower crosscut tun-
mel, then we might as well pull up
stakes and leave the country" was the

is situated at the base of the ridge
on Kanaka creek, the great bore be-
ing pointed to the west, intending to
to the south and 500 feet vertically |
below, the old upper workings. The |
drilling of the holes for the dynamite |
blasts to rend the rock was all done
by hand. The tunnel is by feet in |
the clear. The contact was reached
at 1,150 feet in. It was extended rs |
feet beyond the contact and this cham |

high grade milling ore and quartz
At $50 feet north OF the main tunnel |
the ledge proper was encountered |
showing up strong between two we'll |
defined walls. 1t was then that H. L. |
Johnson of the Tightner felt that ul- !
TINA thule had been reached. The tun-
mel up to that time and point had cost |
a round 100000 in cold, hard cash. |
Some of the rock passed through was |
exceedingly hard, costing $50 per foot. /
The contact was hit just where the |
survey estimates had calculated it |
should be from the< dip and trend as |
shown by the ledge in the upper work
ings. The ledge as now exposed in
the lower tunnel is ideal in its struc-
ture and appearance. 1t is from to |
s feet wide between walls, with a dip
to the east of As degrees, trending
north and south. The quartz lies in |
