East Bay Group Project Number 1304
Sturgeon Lake Area N.T.S. 52J-2-SE
INTRODUCTION
The Last Bay Group consist of six contiguous clain.s (437135-
437130 inclusive; 406610 and 486622) situated on the north
shore of East Bay of Sturgeon Lake. The property is presently
held under option from Mr. Stan Johnson of 18 Front Street,
Sioux Lookout, Ontario.
The property contains three main quartz^yeins^and several
subordinate veins. Two of the main veins are known to be
Au-bearing. The more important veins have observed widths of
up to four feet and although the veins are likely to be
lenticular, tht present mapping survey indicates possible
strike lengths in the range of 200-400 feet. All of the
main veins generally show strike directions varying from
150-400 true.
Access to the property is available by water via Angler's
Cove landing near the town of Savant Lake. Great Lakes Paper's
Camp 700 road apparently passes within ^ mile of the
property, but this means of access has not been examined.
GEOLOGY
General!
O. G. S. mapping (N.P. Trowell, Squaw Lake Area; Map
P.968, 1974; Map 2420, 1980) has identified an I--W trending
monoclinal belt of felsic to mafic volcanic rocks. Present
mapping generally conforms with this interpretation except
...2
Geological Survey - East Bay pg. 2
in the northern portion of the gric' where the combination
of geologic' magnetic surveys suggest the presence of tight
folding. The odd exposure of pillowed lavas indicate tops to be roughly in a southerly direction.
LITHOLOGYi
Mafic Volcanic Rocks
la. Fine to medium grained flowsi This unit is massive to weakly schistose, dark green and chloritic. Locally the unit is amygdaloidal with secondary calcite.
le. Medium to coarse grained flowst these are massive,
dark green and chloritic. This unit is characterized*
by amphibole phenocrysts. The unit may in part be intrusive.
le. Carbonatized flows: This unit is fine grained, chloritic,
weakly schistose and typically calcareous.
If. Pillowed Flowst only two good exposures of pillowed
lavas were noted during mapping. Pillows are generally
well formed and tightly packed. Selvages are approximately
V in width. These rocks are very fine grained, dark
green to black and amygdaloidal. The calcite filled
amygdules tend to concentrate near the rims and indicated top of the pillows.
Felsic Volcanic Rocks
3a Fine grained flows/tufft these rocks are massive very
fine to fine grained, buff to light grey-green in colour
and siliceous. A few small ellipsoid quartz phenocrysts
are locally present.
...3
Geological Survey - East Bay pg* 3
Lapilli tuff: this unit is generally monolithic and
contains sub-rounded to sub-angular clasts. Both the
clasts and matrix material usually consist of material
described below.
Tuff: this unit is similar to 3a but ellipsoidal
quartz phenocrysts and broken alkali feldspar crystals are abundant. A weak gneissosity is often present.
Tuff breccial this unit is again similar to 3c but
angular fragments of 3c up to V in diameter are very
common. The sub-rounded to sub-angular clasts found in unit 3b are usually present.
All of the felsic rocks may'in part be volcanoclastic.
Sedimentary Rocks (Volcanoclastics)
4a Lithic Wacke: These rocks are fine to medium grained
and massive. Matrix material is chloritic and contains
fine Lo coarse sand sized fragments o f quartz j feldspar
and lithic fragments of both the mafic-felsic rocks described above.
4b Conglomeratei this unit is similar to the above but
the lithic fragments of medium pebble size are
abundant. Packing is quite tight {clast supported) with matrix material generally confined to the interstices
of adjacent fragments.
GOLD PROSPECTS
Three areas of interest were indentified during the mapping
survey, although records are not available, all three areas
have been examined sometime in the past by means of trenching
...4
Geological Survey - East Bay pg. 4
and limited diamond drilling (X-Ray drill).
At present quartz veins are the only known Au bearing structures
in the claim group. The veins are weakly mineralized and
carry minor disseminated pyrite an pyrrhotite but iron carbonate
stringers are fairly common. Wall rock is generally
silicified;mineralized with some disseminated sulphide.
Showing A is located in the south central portion of the claim group. Exposure in the area is poor but a series of pits
suggests a NNE trend. A quartz vein is exposed in only one
pit where it was noted to be about 8" in width. Overburden in this area is not likely very deep ^5 feet) but appears
to be heavily bouldered.
Showings B and c both occur in the northeastern portion of the
grid and again show NNE trends. Showing B appears to consist
of two sub-parallel veins approximately ten feet apart. A
small open cut between L20NiL18N at about 3+OOE exposes a
four foot quartz vein. Two feet of vein material is also
exposed on LION at 2+OOE directly on strike with the previous
ve.in. A second vein (i-1 foot) is exposed in a small trench
on L18N at about 1+90E.
Showing C exposed quartz on L18N at about 6+OOE, immediately
south of L16N at about 5+OOE and on L14N at about 3+5E. It
is not known if these three exposures define a continuous
vein but all these occur directly on strike. The vein widths
on L18N '. L14N are both about l to 2 feet. On L16N the veint
has a width of about 4 feet on surface but pinches quickly to
about 6 inches at the bottom of the pit (-ss\2 feet below
surface).
...5
Geological Survey - East Day pg. 5
RECOMMENDATIONS '
Since overburden may present a problem at Shoving A, it is
suggested that manual stripping be tried here first. If
manual stripping proves successful in this area, it vill
certainly be adequate to test the extension i continuity of
the quartz veins at shoving B-C. In the event that manual
stripping is impossible at Shoving A a bulldozer or backhoe
can be used in all three areas. In this latter case,
access to the grid from the Great Lakes haulage road must be determined. Blasting and detailed sampling should proceed in conjunction with stripping.

INTRODUCTION
A description of the property, its history, location and access is included in the geologic report accompanying this submission
and will not be repeated here.
Approximately 1.1 miles of baseline and 7.2 miles of grid line
have been cut by Mr. K. Harrison, contract Linecutter, during
March, 1981. A pair of baselines, two thousand feet apart, were established in order to improve grid control. Both baselines are oriented 005O True.
A horizontal loop electromagnetic survey and a total field piston precession magnetometer survey were conducted over the
grid. These are presented on the accompanying maps at a scale
of l" = 200 feet.
At the time of the initial property examination (June, 1980),
it was noted that the principal Au bearing structures (weakly
mineralized quartz veins) have a NNE trend. The strike trend
of these quartz veins is near normal to the trend of the volcanic
and sedimentary rocks in the area as indicated by O.G.S. mapping (N.F. Trowell, Squaw Lake Area; Map P968, 1974 and Map 2420, 1980).
The control grid was established to traverse the Au bearing
structures rather than the stratigraphy.

Geophysical Survey - East Bay pg. 2
The EM and magnetometer surveys were uieU with the intention of
geophysically defining the known showings on the property.
ELECTROMAGNETIC SURVEY
Aside from a few in-phase responses due to topographic effects,
EM profiles are guite flat. The known showings have not produced any significant electromagnetic responses.
MAGNETIC SURVEY
The greatest magnetic relief on the property is associated with
a band of fine to coarse grained mafic flows and/or intrusives
in the north central portion of the grid and appears to define tight folding in the area.
There is no consistant relationship between the magnetic response
and the known showings. Zone A occurs on the flanks of distinct magnetic high, Zone B within a magnetic low and Zone C within a magnetic high.
CONCLUSIONS
In light of the inconclusive results produced by both the EM
and magnetometer surveys, additional target areas can not be
defined. Trenching and stripping should procede as outlined
in the geologic report and, for the present, be confined to the three known showings.
