GRASS VALLEY QUARTZ
As the operations of the Company are Ioe,,., /, -

proximste idea OF the general average Of the onsrt
this particular region. In lisiting tesmenv -
D. int, shall summon upon the stand az
from the many who or have been PRACTICAL enys

from long experience, Ia Of the opinion that ~. -
Of this quartz will average by the present
ton, two cents TO the pound, 81 per ton The 80,
crushed at the mill Of the Grass Vaey Quartz Miuins

richest veins worked
Hon James Walsh, Senator from Nevada county and mn
petor Of large quartz MILL in writing upon this sub
says: -
q The rock (rom which all he richest rons have b..,
cued) has paid low so per ton and as biRh as 500
per ton The quartz is paying better than at first
think the average OF the quartz in this vicinity will
be found to be about S4U per ton +" WI
The rock that Gold Hit after taking out specmsns
enough 10 pay for working the hill ana excavng rock
will beyond doubt, assay OF five per round
The quantity Of gold bearing qatrz in this Grass yale
district 10 Is impossible Tor any one TO estimate =
Even with high lab imperfect modes Of quarry e. and
very inefficient machinery, the mile making money
James HOugh heavy quartz operator writing on this
subject, under date Of July %, 1851, says:
"Up to the present time have quarrieJ some fourteen
huNdred tons Of rock have had in my eight
twelve daily and have than paid nay entire ex.
penses bs crushing with hand richest portions
Of the rOck, paying at the dollars
day. with board BY this hand opera ion have crushed
quartz yielding as high eghiysx dollars to the pound
and little any, less than three dolarr."
AFTER these specimens have been carefully cued from
the whole OF the by breaking IL up into small pie
ces tn smallest yield OF the remainder when crushed and
amSgsnaed the mill has $40 per ton and the lar
gest that hss under observation a. high as $40
u my opinion, $40 would he fair average OF each ton az
rock.n
Prof Blake science aud thoroughly acquainted
with this subject, whites:
In Grass Valley very rich quartz has been found In
many specimens that have the quartz might have
been said have been literally imbended In the gold rather
than the gola ia the quartz. There can be no
doubt also that quartz in which gold is yi,be TO the
