The San Francisco call. [volume] (San Francisco [Calif.]) 1895-1913, 1897-05-23

The recent rich strikes in the Gwin mine, in
the new 1900 and 400 levels, continue to be
frequently discussed in mining circles. 1t is
observed to have a twotold sign ifcance to
mother-lode mining. Its more general one
lies in lis being the latest and the greatest
deep-mining development, and one calculated
to still further stimulate the era of deep min
ing which has just begun and to strengthen
still more the confidence in motherhood prop
critics.
1t also has local significance, apparently
Between the Kennedy and the Utica is a six
teen or eighteen mile stretch of the mother
lode, on which are good many located mines
and some quite valuable ones, but nothing
corresponding to the deep values of these
great mines had been found Toe Kennedy
is working in good newly found ore body at
$500 feet and the Utica is down about 1000
feet. The Utica is in this gap, and the new
development in its depths seems to connect
the Utica ana Kennedy and to indicate that
the deep-lying values of these may be fairly
continuous along that sec ton of the lode and
be encountered in other places
The discovery is that of thin vein of won
derfuiy rich ore running through a ledge OF
low-grade ore u to IA feet thick In places
the vein matter appears almost pure gold, at
least running IT to the thousands per tom and
II Will give high average TO the whole ledge.
The vein has been traced for a considerable
distance aud It's continuation in depth is OF
course problematicaL new deep shaft will
be sunk al once little farther sou tn and sixty
stamps will be added to the present new forty
stamp mill. The property consists OF four ad-
joining locations along the lode. During the
career OF the mine before the abandonment of
operations many years ago the old shaft was
sunk 10 100 feet and some So 900, 600 was
taken from the comparative short tunnels
run at various levels. Owing to the trouble
with water and the crude and expensive
methods then employed the profits became
little or nothing and operations ceased just
above the riches that have now been found.
The new shaft has been sunk 200 feet below
The old one, and in time the old workings will
be drained through this shaft. When this Is
done and the third shaft driven, there will be
three shafts and vast ore body in sight that
could not be worked out in two generations, be-
sides the unm ensured promises OF riches deeper
down. This mine, which was bonded two
years ago for S200,0 now takes its place as
one OF the greatest and richest gold mines of
California, with probable value of millions.
And there is a certainty that there are other
OWNS on the mother lode
During this week the executive committee
OF the California Miners Associ alton will meet
TO consider the question of participation IN
the gold mining convention 10 be held in Dem
yer, July z, and g. Many of the leading
mining men OF this State will attend this i'm
portant gathering in which California has as
much interest as any State The official call
Tor the convention has reached various Off
Gals and organizations here, and it includes
the following statement of the scope and pur
poses OF the gathering:
The objects of the convention are TO secure such
National legislation may be calculated TO pro-
no the business interests and development OF
the resources of the mining Industry in North and
south Amertca: TO bring together mining men
and investors; to Increase reciprocal trade among
them: to discuss such questions as are naturally
suggested By its Objects to cultivate acquaintance
haternai feeling and hearty cooperation among
the various mining, commercial and labor bodies
represented, and sperially to take under advise
ment the importance of the creation by Congress
OF a department to be known the Department
OF Mines AMI Mining, thus occurring a Cabinet
officer that represents interest which affects
more than one-thiTd of the people Of the Z nted
States.
II is hoped that this convention will prove to be
the creates. and effective effort ever made in
the interest of mining therefore the Governors of
states and Territories, friendly nations, County
Commissioners, Mayors of cities and towns, all
mining. commercial trade and labor organizations
are urged to take no Of the matter at once and
not only see that their delegates appoin ed and
attend the convention, bul that attractive and
thoroughly educational displays of minerals are
made from every mining district
