The bill on which the oimnabar showings are found is
‘underlain by interbedded Pormfan ribbon chert, quartzite, schist, lime-
stone, and minor greenstone. The quartzite and ribbon chert form beds
+ inch to 2 inches thick, commonly minutely crumpled. Normally the beds
are separated by thin partings of argillite, but in the vicinity of the
mine the partings have been largely altered on mica, and the rocks are
grey and brown, quartz-mica schists, Noar faults some carbonate has been
introduced and the rocks are quartzemicaecarbonate schists, Several bands
of grey-green, quartz-glaucophane schist were observed to the west of the
"nine hill". Limestone occurs in belts up to 600 feet thick, It is the
normal blue=-grey variety, but along and near the feults it has been partly
to completely altered to buff weathering dolomite and is partly stlicified.
Silicification has resulted in the formation of masses Be white, cherty
quartz throughout the limestone. Lenses of freen, chloritic schist occur
underground at the mine.

The hill north of the "mine hill" is underlain by Jurassic
andesites. hey are principally green to greenish grey rocks with pheno-
erysts of feldspar and pigeonite. The contact between the Permian and
Jurassic eset could not be observed here as it is along a drift-covered
dra aw north of the mine hill. However, relations elsewhere along the
mercury belt “suggest it is a fault contact. }

.

The Permian schists are intruded by several small bodies of
altered serpentine. The largest of those bodies is about 600 feet in
diameter, The least aatensds phases are dark olive-green rocks with the
texture of coarse pyroxenites, but composed almost entirely of antiforite
serpentine that has beon largely changed to buff- and cream=coloured, magne»

sitic and ankeritic carbonates, quartz, and - gen mica, All gradations
from serpentine to carbonate may be observed

cut nit two elliptical bodies of grsenstone, each 800 by 200 fe They are
composed largely of glaucophane, pigconite, and elinozoisite, Those green-
stones may represent intrusive phases of the Jurassic volcanic rockse

West of the "mino hill" the Pormian schists and limestone are

Structural Geology

The Permian strate have a general northwest strike and dip
steeply northeast, but in the vicinity of the principal ore-bodies the
attitudes are quite difforent from this. ‘The ore-bodies oceur slong or .
near northwe asterly trending faults cutting folded Permian rocks (See
Figure 1). The aya important fe ault, called the "south fault” » strikes
approximately north 60 degrees west and dips 50 Eos 70 degrees SOME OGIED

The trace of this fault is along tho erest of the “mine hill". The "south
fault" has beon followed from the glory hole 1;600 feet southeast, whero
it is overlain by drift, and 900 feet oR tan where it appears to divide
into an intricate group of closely spaced:faults. This fault has been
observed on all the levels of the mine, Along the fault the rocks are
brecciated and silicified across a zone 4 to 50 feet wide, The brecciated

zone is bounded by slickensided slipwall surfaces, The strata on the
southwest side of the "south fault" form the southwost limb of a syncline
plunging to the southeast. The beds dip from 60 to 80 degrees to the
northeast. Thev have been disvlaced upwards with respect: to the beds on
