phuret of silver, argentite and mala-
chite. the three last mentioned FREEDOM
mating at the bottom of the shaft.
At the base of this range many varie-
ties of metamOrphic rocks crop out at
the surface; gneiSS, mica-Schist, Syenite|
are the most predominating, while the
general formation at the Richmond
basin is quartZIte. Porphyry, teldspar
and chlorite in some places figure con
spicuously, through which the Rich
mOnd vein passes in an easterly and
westerly course, through rocks that
were confOrmable to the silurian, thus
for the chlorides. brOmides

filtration and decomposition pseudo

in these veins, such as brittle sulphuret
of silver and agentite. At the same
time the foothills within "A mile are
composed of limestone, cOnglOmerates
and crystaliZed sandstone, with &C
casionally some beds of ShaleS of the
primOrdial period. The conglOmerateS

THE RICHMOND VEIN
Is traceable for many miles, The first
extension east has a shaft which is p
feet deep, at which point the vein is
over six feet wide, showing good min,
eral ore from the grass roots down, and
improving as depth is obtained. Over
10 to 10 tons of ore are piled up close
to the shaft (Which was taken out OF
said shaft that will average from BOG
to 500 OF. of silver per ton, while the
tirst-class, if sorted, would be very rich,

from the same, that run over 1000 o.

this portion of the district can he sue
