The Black range. (Robinson, Socorro County, N.M.) 1882-1897, 1883-10-12

made until IL worked X a charm.
Three weeks were consumed in expert
menting and getting the ten tons taken
hither u through in a satisfactory
manner. or the ores, competent mill
runs assert that all of those shipped 10y
Mr.. Castle are concentrating ore, some
Of course being more difficult than 9TH
ers. The assays were made by the
chemist of the Agricultural college at
Manhattan, Kansas. and there could
be no prejudice nor bias entering into
his work. The following are the assay
returns and Mr.. Castles remarks con.
corning the workings Of the individual
ores:
SILVER MONUMENT, works No. l in
every way. Through concentration;
95 per cent. saving; value SO ounces
silver; runs IL tens to one. Sample
bags of first-class ore run 1897 per ton
silver.
WHITE SIGNAL, works first class es-
p~ecially that from the tunnel; 90 per
saving; value 80 ounces silver. That
from the shaft was also good ore and Of
good concentrating quality; value Al
ounces; can work it close.
BLACK KNIGHT, some loss of blue
and green but general saving good 81
per cent. saved; value "a ounces silver;
with larger amount can adjust the ma
chinery to the work and save nearly
all.
COLOSSAL, works No. 1 in every way.
Through concentration; SO per cent.
saving; value 80 ounces silver; runs II
tons into one; can use to advantage.
DREADNAUGHT. When there was
any separation of mineral in the ore a
good concentrate was obtained; with
mineral mnutely diffused it all came
through as concentrates, or if water
was strengthened 1t all passed away in
waste; ore will have to be sorted, then
it is good concentrating ore; value A
ounces silver; with care can save 80
per cent. and run sew en- or eight tons to
, one.
PALoMAs CHIEF. Did not get the
machinery adjusted to save any ore;
, but upon examination by mill men they
say 1t will run and concentrate well.
BY hand trial a good separation was
obtained; value of sample 26 ounces
&, silver; can work it by care.
DEFIANCE. Works very fair; some
loss of blue ore the value of which was
, q ounces silver; 80 per cent. saving;
value of sample 81 ounces.
; MIDNIGHT. First class; a save
the full limit; all black oxides also
value 37.7 ounces; can run IL to one.
LITTLE PITTsBURe. Only fair; blue
and green difficult to save, 80 per cent.
agood amount of saving; will run near
. 40 ounces.
: MONTE CHRISTIE. Works only fair
. blue and green difficult to save; can
save almost 80 per cent. of mineral
: &4aa q sample taken SO ounces.
SILVER GLANCE. Good; will a v up
: to 90 per cent; some loss of green and
blue: value 4S ounces; can run ten to
one.
WHITE SHIELD. Good; concentrates
well and with little loss; value 81 oun'
: ces; ear run 10 to one.
COPPER BELT. Not so good as the
others; could not adjust the machinery
I to so small an amount of ore; can give
no definite report. a fuller test will
be necessary when the machinery is in
operation; valve 23 ounces
e vALTA. By care can concentrate but
I can run but few tons into one; as with
all the ores containing blue or any green
the specific gravity of those colors is SC
slightly different that it will make
dirty concentrate. Value Of sample
y 81 ounces.
: BUFFoM. Only fair; when mineral
is dlffused it is almost impossible to
Q concentrate but when it is separate
: from the gangue it is all o. K; value A
. ounces.
s BLUE DANDY. Works very fair
Q some loss OF blue ore; value q ounces
. silver: a ave SO per cent. and can
3 run eight to nine tons to one.
READJUsTER. Good ore tn concen'
trate; like the Colossal as to concen'
v trating qualities; value 81 ounces; car
g run ten to one; can use all you can
II bring Of it.
The Colossal, Silver Monument
Dreadnaught and Midnight ore mixed
gave 1873 per cent. copper, Az ounces
9 silver and one-tenth of an ounce Of
gold. To run properly and make q fail
Q test about fifteen tons of each kind Il
o required.
