The government report further shows III It's feature on the
genesis of the Occur Aene deposits probable uniform
increase with depth to haser and refractory OF
pvrrhotte and pyritc combinations While this is apparent
instances there are some very SHARP t"hi''

fomy clean lead at It's bottom level even devoid OF lhe
usual accompaniment OF iron carbonate and carries iaeeo
no zine.
In regard to the Prichald formations, am OF the opinion
that they will carry deep as amy OF the other formations
the district. Recent development shows that there Is not
my question as whether the bodies Will go down inf
he Prcard slates for matter OF fact they have gone

1.-THE fssure.
The same is true Of the Monarch which for several years
was doubtful prospect by of the fact that Its 5000
foot lower tunnel failed to find the downward continuation OF
the main ore body which, however recent development mas
shown was due to fautng and horizontal dispacenent hs
trouble has since been thoroughly studied and worked ol
successful conclusion showing remarkable strength lor t
ore channel to the present lowest level 400 feet below the
crest of the ore body with rich Slopes at the 20ioo level eeal
through to the surface
These results materially broaden the field Of ore pro hue
mo possibilities of the Occur les the Pricard tora
ons are more extensive than all the other formations coo
ed in surface area and relatively we'll assured Nne
is fact SO far as development has progressed the ore bodies
this particular formation have proven shorter they are Sho"
to be repeated where the assuring conditions are strong con
tain very clean ores both lead and zinc, and unqueS'on'
warrant extensive development with definite prospect OF De
coming important sources of rich shipping and concentrating
ore as it apparent that the rich solutions showed t
same selected preference for agte they dd for q'z
| in several important instances.
| From the almost uniform experience OF finding the orr
bodies of this district practically blind at the surface Is cV
dent that the contours Of the country have suffered very "
erosion since the ore bodies formed that the sulIa
erosion has not extended deep enough to destroy Their ue
! limits and consequently body found III the lrlcla
states is still all there and should have as great range
