MINING NOTES.

a miner at Balh Choop, Shasta, lately
cleaned up S5S2 from eighteen ions of rock.
The Gold Stripe, Greenville, Plunas
county, is now running thirty-five stamps
on good pay rock.
The Murray mine, Spring creek, Shasta
county, has drifted $50 feet and shows as
says of from $50 to $50 per ton.
The largest piece of geld ever found ia
said to be the Australian nugget known ss
the 6 Sarah Sands, weighing 2iS pounds
ounces troy.
The rich idaho and Vishta mines. Altu-
ras county. Idaho, have Just emerged from
series OF legal complications. Work will
now be pushed rapidly.
Lately, says the Oroville Register tbs
Superintendent of the Spring Valley Gold
Mining Company brought in a brick worth
S76, 600. the product of six days run from
only part of the sluices.
The Aountain Echo, Calaveras. saws
The proprietors of the Dolan and Cogswen
mine cleaned up $500 last week. This is
pretty good when we consider that only
tive men are employed to run the mine and
mill.
George Tompkins has discovered a very
iiSH VI dI OTO ClnO, NlskIyON
county, which is about fourteen inches
thick. From piece of rock about as
large as hens egg upwards of $40 was
realized.
Near Georgetown, FL Dorado county, in
the preparations made by the settlers to
meet the claims of the Railroad Company,
two men set to work in an old, longtime
abandoned cut, hoping to obtain enough
gold to pay for the food they would con-
sumo while working the ground, and to
their astonishment they have made as high
as $50 day in good coarse gold.
The latest excitement in the quartz hna
in Sierra county is the striking of some
very rich quartz in the Forest Queen mine,
near the mouth Of Slug canyon, Downie-
vile. About week ago q small seam
was struck, and in running some five feet
the ledge widened cut to nearly four feet
wide. Several tests made the first of this
week ranged from $50 to 500 per ton.
Considerable of thinning breeze has
been raised in the Granite Basin country,
Plumas county, during the past few weeks,
and quite a number of new men have COM
menced operating in quartz there. The
ledges are uniform in size and the quartz
nearly all of the same character, most of it
being filed with sulphurets. Some assays
of the sulphurets made lately show as high
as 81, $50 per ton.
At the Murchie mine, Nevada City, the
frame for the new hoisting works, which
are go feet west of the old ones, IS up,
and the building will be completed in
about a week. The machinery with O
capacity of sinking 900 feet, wi be there
by the 18th ult., and be in operation by
December lst at the latest. A water
power compressor is to be used for drilling
and pumping, but the hosting will be
done by steam. The new twenty stamp
mill with eight Frue corcentrators will
stand about seventy feet from the mouth
of the shaft. The timbering will all be
new, but about three-fou1ths of the ma
chinery in the present mill will be utilized.
With these improvements all made, which
will cost in the neighborhood OF $50, 000,-
it is estimated thatexclusive OF chlorinatior,
the expense of milling will be sixty cents
per ton, and of mining from 50 80 to 81.
The Mammoth Bar mine, on the Middle
| Fork of the American river, near Auburn,
is represented to be giving very encourag-
ing prospects. This claim is on portion
of the river bed that never could be worked
In early days of river mining, because of
the great depth of the gravel, and the i'm
possibility of getting to the bottom of the
channel without the aid of deep working
machinery. The ground has been contin-
uously held for many years by Grass Val
leyans, and last season an Incorporated
company was formed to work the claim
under the above name. Strong steam
machinery was set up on the river bank.
and perpendicular shaft sunk to depth
below the natural bed of the stream, and
then a bedrock tunnel run under the chan
mel. From this tunnel three upraises have
been made into the gravel at different
points, and prospects obtained which aver
age twenty five cents to the pan, which, AZ
miners understand, is "big pay" A good
deal of water has been encountered, but
this is easily handled by the large pumps
which are used, and the gravel channel is
being gradually drained, SO that the ex-
traction of the gravel can soon be COM
menced. The depth of the gravel is from
sixty to seventy feet, but the ''pay" is
looked for on the bedrock, where the
stockholders hope from the former rich
ness of the river above and below the
claim that 'mule loads " of the shining
ore viii be found. .-[Grass Valley Union.
