SUMMARY
Field exploration work for Tuscaloosa Oil and Gas Inc. was conducted on a
12 claim group gold prospect located 17 kilometers east of Marathon, Ontario,
within the Thunder Bay Mining Division.
Field work consisted of limited geological mapping, a reconnaissance I.P.
survey, an airborne VLF-HEM electromagnetic and magnetic survey and an
overburden drill program.
A critical facet of the exploration program was the determination of the
relationship between the property geology and its economic potential to the
Hemlo gold ore deposits, a recently discovered major gold camp situated just off
Highway 817 (Trans-Canada Highway), 30 kilometers east of Marathon, Ontario.
It is concluded based on field work done to date that the property is
geologically well situated and has reasonable exploration potential to host
another Hemlo-type gold ore deposit. However, due to thick accumulations of
glacial overburden traditional methods of exploration were not adequate,
therefore an overburden drill program was used.

1.0 INTRODUCTION
Field work on the 12 claim gold prospect of Tuscaloosa Oil and Gas Inc. was
designed to locate Hemlo-type gold ores of the type presently being evaluated by
Corona-Teck, Noranda and Long Lac, on their respective properties near Hemlo,
Ontario.
The key facet to this work was to gain a thorough understanding of the
geological setting of the property and the relationship to the Hemlo gold
deposits.
The primary objective of the 1983 field program was to carry out
geological, geophysical, and geochemical evaluations of the Tuscaloosa Oil and
Gas Inc. claim group as prelude to a further, more detailed exploration program
which would include diamond drilling.
2.0 LOCATION and ACCESS
The Tuscaloosa Oil and Gas Inc. claim group is centered approximately 15
kilometers west of Hemlo, Ontario, and 17 kilometers east of Marathon, Ontario.
The Marathon community serves as a center of communication and supply for the
area.
The Trans-Canada Highway (Ontario Highway ttl?) runs east-west through the
central portion of the property.
The CP Rail line barely transects the southern edge of the property.
- 2 -
One 115,000 volt Ontario Hydro transmission line runs generally parallel to
the highway lies within 500 metres of the northern claim boundary.
Water for exploration and development should be available from various
creeks and swamps on the property while water for potential mining and milling
operations could be supplied by the Black River which passes just north of the
property.
3.0 EXPLORATION FIELD WORK
Field work was carried out under the direct supervision of Jacques
Dumouchel, Project Geologist. Overall direction was provided by George Cavey,
Consulting Geologist, OreQuest Consultants Ltd., Vancouver.
Initial field work which established a 17.1 line mile grid was carried out
by D.B. Sutherland, Consulting Geologist under contract for Mid-Canada
Exploration Services.
In February and March of this year, approximately 17.1 line miles of
VLF-Electromagnetic and magnetic surveys were conducted over the property
utilizing this grid.
Work conducted between mid-July and mid-August consisted of prospecting and
claim post survey, followed by a reconnaissance I.P. survey and a regional
overburden drilling program. The I.P. survey was conducted by M.P.H.
Consultants while the overburden drilling was contracted to Heath and Sherwood
Drilling of Kirkland Lake, Ontario.

3.1 CLAIM STATUS
The Tuscaloosa Oil and Gas Inc. property consists of 12 contiguous,
unpatented mineral claims which encompass approximately 420 acres. The claims
are held in good standing and have a 1984 expiry date.
The claims are as follows:
Claim Number Total Expiry Date
TB 632697-632708 (14) October 15, 1984
4.0 GEOLOGY
4.1 GENERAL CONSIDERATIONS
Gold deposits of the Heralo gold camp are unique in their stratabound, sheet
like nature of mineralization. Gold and molybdenum are the primary economic
minerals with assay grades 0.19-0.36 oz/ton Au. and up to Q.08% Mo. Updated
reserves for the Hemlo camp total 75 million tons grading 0.28 oz/ton Au. To
date three major deposits have been discovered, the Corona-Teck, Noranda-Golden
Giant and the Long-Lac Mineral camps. The latter is reported to be the largest
with reserves in excess of 43 million tons of which 32.0 million tons grade .20
oz/ton.
The deposits occur within an Archean eugeosynclinal rock sequence with
mineralization confined to the contact between a felsic volcanic member and
clastic sedimentary rock member and are directly associated with local sericitic
alteration and disseminated pyritic mineralization. There are also reports of
other gold-bearing horizons in the immediate stratigraphy, but no proven
tonnages have yet been outlined.
- 4 -
Initial reports of gold in the Hemlo area dates back to 1945 when a
prospector discovered gold mineralization within a zone of sericitic-pyritic
alteration located approximately 1,000 metres west of the present International
Corona-Teck deposit. Assays from this zone ran up to 0.4 oz/ton Au.
The gold ores at Hemlo appear to exhibit both stratigraphic and structural
control. These deposits are thought to be actually part of a discontinuous
sheet of mineralization which has been traced for over 5,000 feet on surface.
Mineralization is known to extend from surface on the Long-Lac Minerals property
(Williams pit) to a depth of 3,000 feet on the Noranda-Golden Sceptre-Goliath
property to the north. The thickness of the mineralized zone varies
considerably from about 10 feet in some areas on the Teck-International Corona
property to an average of 70 feet on the Noranda-Golden Sceptre-Goliath
property.
The Corona-Teck east zone deposit is at a depth of approximately 400 metres
below surface and was discovered by deep surface diamond drilling based on
stratigraphic projections of the favorable volcanic-sedimentary contact horizon.
Geophysical techniques, particularly magnetic, electromagnetic and induced
polarization (I.P.) techniques have been tested over the ore horizons and to a
certain extent these techniques have proved useful.
There is usually a soil geochemical expression in gold and molybdenum
associated with the ores.

4.2 REGIONAL GEOLOGY
The general geology of the area surrounding the Tuscaloosa claims is shown
on Map 2439, "Heron Bay, Thunder Bay District", published in 1981, scale: one
inch to one half mile (O.G.S.) and Map 2452 "Hemlo, Thunder Bay District,
published in 1981; scale one inch to one half mile (O.G.S. Report 217).
Early Archean volcanic, sedimentary and plutonic rocks constitute bedrock
for most of the map area (Muir, 1982). Several occurrences of siltstone, wacke,
shale and chert units appear within and adjacent to the pyroclastics.
Major faults in the area seem to coincide with the Pic River valley and one
or more of the east-trending valleys parallel to Platyer Harbour (Muir, 1982).
The dominant rock types in the Heron Bay sequence appear to be a series of
intercalated volcanic and sedimentary formations, as follows:
(1) Mafic metavolcanic rocks mostly of calc-alkalic composition. Suchrocks consist of massive fine-grained medium to dark green flows and their associated pyroclastic units. Locally medium-grained flows or gabbros are also present;
(2) Intermediate to felsic metavolcanics, mainly pyroclastic in nature. Many of these rocks appear as medium green tuffaceous units with suggestion of layering and inhomogeneous textures;
(3) Metasedimentary units consisting of clastic and chemical depositionaltypes. Most the clastic metasediments in the Hemlo area are siltstone with minor occurrences of argillites, shales and laminated clastic wackes which may be derived primarily from volcanic source areas (Muir, 1982; Bell, unpublished report 1982). Chert-bearing banded iron formation and bedded chert carbonate-pyrite-bearing units are also locally present in pockets throughout the Hemlo-Heron Bay map area.

Structurally the volcanic and sedimentary units have conformed, as Muir
believes, to outline the main granitic intrusive plutons which are the Gowan
Lake Pluton, the Heron Bay Pluton, the Pukaskwa Gneissic Complex and the Port
Coldwell Alkalic Complex. Muir (1982) also suggest that the granitic plutons in
the map area are probably syntectonic to late-tectonic whereas the Port Coldwell
complex is likely post-tectonic. Thus he suggests a synform structure between
the Gowan Lake and Heron Bay Plutons.
The appearance of well formed pillow tops, indicating a south structural
facing, approximately 1.5 kilometers south of the Trans Canada Highway on Heron
Bay Road supports Muir's theory. Muir, (1982) suggests that metamorphism is of
low grade, low temperature greenschist rank.
Swarms of Proterozoic mafic to felsic dykes and possible sill structures
intrude the plutons and their associated metavolcanic and metasedimentary rocks.
5.0 EXPLORATION RESULTS
5.1 PROPERTY
The overall positions of the claim block, which has been staked in
compliance of the Ontario Ministry of Mines Act, and the position of the grid,
have been accurately located with respect to regional geography.
The topography of the Tuscaloosa property is best summarized in the
qualifying report by David Bell. Mr. Bell states: "Personal mapping experience
and photogeological studies along the Hemlo volcanic belt indicate to the writer
- 7 -
that the topography is more rugged than in many parts of the Precambrian Shield,
though local relief nowhere exceeds about 100 feet. On the Tuscaloosa Oil and
Gas Inc. claim group, rock exposures are separated by marshy ravines and sandy
knolls. Only a few outcrops occur trending east-west. Ground examination and
aerial photographic studies of the Tuscaloosa Oil and Gas Inc. property show it
to be extensively and densely forested with black spruce, balsam fir and
scattered jack pine. Undergrowth consists of moose maple, tag alder, labrador
tea and sphagnum moss."
"Overburden consists of unconsolidated Pleistocene detritus, mainly boulder
clay, tills and varved clay deposits commonly exposed along the river and creek
bottoms. Depths of overburden are expected to be deep (50*4), regionally
expressed as a glacial depression filled with Pleistocene tills."
"The availability of water on the Tuscaloosa claim group is accessible from
the Black River."
5.2 HISTORY AND PREVIOUS WORK
A search of the assessment work filed in the Resident Geologist's Office,
Thunder Bay, indicated that previous exploration work has occurred on the
Tuscaloosa Oil and Gas Inc. property. During 1975 Noranda Mines Limited (Geco
Division) performed ground magnetometer and ground VLF electromagnetic
geophysical surveys as well as a geological mapping survey. The geophysical
surveys indicated coincident magnetic and electromagnetic conductors south of
Highway fi 17 and north of the C.P.R. on the southwestern third of the present day
property. The conductors wer explained by Noranda as faulting in the area and
- 8 -
also due to the presence of a magnetic amphibolite (mafic metavolcanic) unit or
a strongly magnetic dike found in the area (Graham and Weeks, November 1975, p.
3 and 2). The geology survey report indicated that no significant sulphide
mineralization was encountered (Graham and Weeks, August 1975, p. 3).
5.3 GEOLOGY
The northeastern portion of the property, immediately north of Highway 817
is occupied by a low-relief ridge trending west-southwest, east-northeast of
Early Precambrian (Archean) mafic metavolcanics intruded on the south by the
Early Precambrian (Archean) felsic Heron Bay Pluton end Early Precambrian
(Archean) late felsic dikes. The ridge extends as far west as Line 4400 West.
The southwestern portion of the property immediately south of Highway 817
and north of the C.P.R., is occupied by a ridge trending west-southwest,
east-northeast of Early Precambrian (Archean) mafic metavolcanics and lenses of
intermediate to felsic metavolcanics. The metavolcanics are intruded by Early
Precambrian (Archean) late felsic dikes. All Hthologies south Highway 817 are
intruded by a north-south trending Middle to Late Precambrian (Proterozoic)
mafic intrusive dike of diabase.
The mafic metavolcanics are generally dark green, fine grained, foliated,
amphibolitized rocks of basaltic composition. They range from being massive to
vesicular to sheared and schistose, the schistose portions commonly displaying a
rusty gossan and minor pyrite. Layers or thin laminations of sericite (altered
feldspathic material) and/or epidote are frequently present with the fine
^^ grained mafic metavolcanics as well as calcium carbonate. The very fine grained
- 9 -
amphibolites have a slaty structure. Massive medium to coarse grained flows are
also present, bearing amphibolide and feldspathic material, but are seldom
foliated. Amygdaloidal flows containing amygdules of plagioclase and sometimes
calcium carbonate, are also present. Tuff and lapilli-tuff of intermediate to
mafic composition is apparent, with one outcrop south of Highway 817 bearing a
graphitic schist. The overall foliation trends of the mafic metavolcanics vary
between 230* west-southwest to 270* east-west and dips are vertical to 36* north.
Felsic dikes of various composition and grain size intrude the mafic
metavolcanics and parallel their foliation.
The intermediate metavolcanics are observed as tuff, lapilli-tuff in
association with the mafic tuff and lapilli-tuff.
The felsic metavolcanics are observed as two narrow lenses and few
scattered outcrops south of Highway 817, of foliated flows and/or tuffs ranging
from a buff sandy colour to light green depending upon feldspathic content
versus epidotization. Epidote often occurs as narrow, apple green stringers.
Fine quartz eyes and granulated feldspar phenocrysts (tuffaceous) are observed.
Foliation trends and dips are the same as the north and south bounding mafic
metavolcanics.
The Heron Bay Pluton, observed only north of Highway 817 near the eastern
property boundary occurs as a hornblende-biotite granodiorite.
Late felsic dikes of various composition and grain size intrude the mafic
metavolcanics parallel to foliation trends. Compositionally the dikes are
- 10 -
generally massive feldspar porphyry containing plagioclase phenocrysts of medium
to coarse grain size. Where quartz eyes are present or the siliceous content is
dominant, the unit is referred to as a quartz-feldspar porphyry. North of
Highway #17 aplitic dike material is associated with occurrences of feldspar
porphyry.
A mafic medium grained equigranular diabase dike, trending north-south
intrudes all lithologies observed south of Highway 817. The diabase dike does
locally grade into a porphyritic variety near its south end. A rusty brown
crust is common on the weathered surface, the fresh surface being a
greenish-black.
An ENE trending lineament cross-cuts the property and is probably caused by
a major fault structure.
5.4 OVERBURDEN DRILLING
Due to extensive thick overburden cover on the property, conventional soil
geochemical surveys were not carried out as proposed. To obtain reliable data
from a geochemical survey a depth of 6 to 10 metres of overburden is considered
the limit.
The proposed overburden program was considered as the only viable
prospecting tool available to properly evaluate the potential of the property.
The aim of the program was to delineate any gold dispersion trains in glacial
till and to sample and identify the underlying bedrock. Because of the large
sampling medium the program was extended to four neighbouring properties and the
- 11 -
data treated together. Drill holes were located two hundred metres apart on an
northwest-southeast trending traverse lines. The traverse lines were oriented
at 90" to the ice direction and separated by 600 to 800 metre spacing.
Using a nodwell-mounted reverse circulation drill, the operation was
continuously monitored by a geologist responsible for logging the chip slurry
and sampling both the till and the bedrock.
Samples of till taken at a standard 1.5 metre intervals were sent to
Overburden Drilling Management of Ottawa for size fractioning and identification
of gold grains. Using parameters such as the size and texture of gold grain,
the relative amount of travelling from their point of origin is determined
{Figures 3 to 6).
An anomaly resulting from this first exploratory stage would require follow
up overburden drilling at a closer spacing followed by diamond drilling.
The fine fraction of till and bedrock samples were also analyzed chemically
by Bondar Clegg geochem lab in Ottawa for copper, zince, molybdenum and gold.
Two drill holes from a total of 24 holes were completed on Tuscaloosa claim
block. Both holes were abandoned in thich gravel/till beds without reaching
beadrock. Drilling indicated that most of the property is covered by at least
120 metres of overburden therefore exceeding the capacity of the drill rig. As
in the deeper holes depressions have been filled by thick accumulations of
gravel and washed till.
- 12 -
Only one gold grain was identified from a till sample taken from hole
EP-01. It appears to be of distal origin.
Geochemical analyses by Bondar Clegg of Ottawa of the 1/4 sample split
showed only one truly anomalous sample. Values greater than 3,000 ppb Au in
till samples are considered anomalous in this type of survey {Averill-Overburden
Drilling Management, personal communication). One sample RC-IT-10-13 was
conered anomalous, with a gold value exceeding 15,000 ppb. The sample was taken
at the bottom of hole IT-10 in gravel till. Unfortunately it occurs as a single
point anomaly as none of the samples taken above it were anomalous and the hole
was abandon without reaching bedrock.
Overburden Drilling Management concluded that, "Our study shows that
neither free gold nor auriferous pyrite is present in the retained 1/4 split of
the anomalous IC-10-13 concentrate. It is therefore reasoned that the strong
anomaly in the 3/4 split was produced by a single coarse gold grain. Anomalies
of this type are of no significance, even when they occur in tills. The anomaly
occurs in a gravel horizon at an unknown distance above bedrock. Follow-up is
not warranted". (S. Averhill, November, 1983)

5.5 GEOPHYSICS
Results of the one line-mile reconnaissance I.P. survey conducted on the
property in July 1983 were inapplicable by the failure to penetrate the thick
conductive clay overlying the bedrock. The ground geophysics performed by
Noranda Mines Limited in 1975 suggests the presence of a coincident magnetic and
VLF (very low frequency) electromagnetic conductor south of Highway 817 on the
southwestern third of the present day property. This may be explained by the
present geology survey as the following:
(1) There exists a schistose shear within the mafic metavolcanics that has a significant distribution of rusty gossan and an exposure of graphite. The same zone is also calcium carbonatized. Thus the zone is a likely explanation for a VLF electromagnetic conductor;
(2) A lithological change occurs immediately south of the rusty, schistose zone of mafic metavolcanics, where a lens of felsic metavolcanics occurs. Such a lithological change could also explain Noranda's coincident magnetic and VLF electromagnetic anomalies (ie: magnetically, felsic volcanics have a near nonexistent magnetic mineral content while amphibolitized mafic metavolcanics, by comparison, have a relatively high magnetic mineral content).
A geophysical report by Sutherland dated May 1983, suggests the presence of
three significant VLF (very low frequency) electromagnetic anomalies, Zone A,B
14
and C.
Zone A, north of Highway fil? and extending from the eastern property
boundary west to area between Lines 4400 West and 4800 West, wraps around the
western nose of a topographic ridge of mafic metavolcanics which is surrounded
to the north, south and west by sand plains and swamps. Thus Zone A can be
explained as the results of a topographical interface between a ridge and
overburden.
Zones B and C, according to Sutherland, display good to moderate
electromagnetic conductivity but have no definite magnetic correlation. Prom
the present geology survey, Zone B appears to coincide with the larger lens of
felsic metavolcanics south of Highway 817 and can be explained as an anomaly
related to a lithological change. Zone C correlates well with the exposure of
graphitic schist located south of Highway #17 on Line 8000 West at approximately
124-tOO South.
A study of the magnetic data obtained from the combination of all ground
and airborne magnetic survey available for the Tuscaloosa Oil and Gas property
and the Hemlo gold belt has enabled us to correlate favourable stratigraphic
horizons across the property.
The property can be divided into two E-W trending magnetic domains. A high
magnetic domain occupying the southern part of the claim group correspond to the
outcropping mafic volcanogenic unit.
- 15 -
The low magnetic response delineated in the remaining portion of the
property reflects the presence of metasediments or possibly felsic volcanic
rocks.
6.0 CONCLUSIONS AND RECOMMENDATIONS
Exploration of the property has been hampered by the lack of outcrop
exposures and deep overburden cover. Conventional exploration methods such as
soil sampling were replaced by an overburden drill program. In a few cases the
overburden drill holes had to be abandoned without reaching bedrock because
depths exceeded the capacity of the drill rig.
Further overburden drilling is not recommended because of the lack of a
well developed basal till.
From our knowledge of the "Hemlo" stratigraphy it appears that the
favourable horizon occurs at the interface of the mafic volcanogenic-felsic
volcanic rock units and the overlying metasediments. These stratigraphic units
are easily identified using magnetic data and have been recognized on the
Tuscaloosa Oil and Gas property.
Furthermore a fault structure cross-cutting the property may serve as a
locus for fumarole centres within the sedimentary basin.
According to our exploration model exhalitive facies hosting the Hemlo gold
depsoits are most likely to occurs in small sub-basins or grabens with the
exhalitive centres probably located along the faulted boundaries.
- 16 -
The recommended program would require fence type diamond drilling along a
north-south section across the basin. This will provide valuable stratigraphic
information and hopefully verify the presence of altered felsic volcanic rock
and/or an exhalitive horizon. Lithogeochemical analyses of selective drill core
sections would help detect any traces of hydrothermal activity related to ore
forming process at particular stratigraphic intervals.
Given the logistical problem created by the depth of overburden in diamond
drilling it is recommended that a seismic or gravity survey be undertaken prior
to drilling to assist in the selection of drill sites. The seismic survey also
has the potential of identifying baritic facies associated with gold
mineralization as barite act as an attenuator of seismic signals.
It is also recommended that prospecting and rock sampling of the rusty
gossan, mafic metavolcanics {Zone C) on the southwestern portion of the property
be considered.

The properties form a contiguous six mile by three mile block
centered roughly five miles west of the Village of Hemlo
(Figure 1).
The objectives of the surveys were to explore for sulphide
horizons similar to the horizon which hosts the gold deposits
under exploration and development on the International Corona
Resources, Lac Minerals and Goliath Mines/Golden Sceptre Mines
properties.
The surveys provided reconnaissance coverage of the properties
involved at more or less equispaced intervals and at the same
time traversed a number of conductors that were outlined by
VLF-EM surveys conducted on the properties.

The surveys were conducted with a Huntec time domain induced
21 polarization sytem consisting of a Mark IV receiver and a
M| 2.5 kw transmitter/motor generator. Appendix I contains
detailed specifications of the instruments used.
iIn the time domain induced polarization method, current is
^B transmitted into the ground through a pair of electrodes
mm ( current dipole). At a pair of remote electrodes (potential
dipole) the primary voltage which is a function of subsurface
resistivity and secondary voltage, or the induced polarization
effect which is a measure of polarizeable mineral content, are
measured. The transmitted current wave form is a modified
square wave consisting of on-off-on-off cycles of equal
duration, in this case two seconds. The primary voltage is
measured during the on cycles and the induced polarization
effect is measured during the off cycle. The principles of
time domain induced polarization are illustrated in Figure 2.
The Huntec Mark IV receiver measures the induced polarization
parameter chargeability on 10 individual channels. Channel
width (Tp) and delay time (Td) between current 'shut off and
beginning of the measurement are adjustable to suit the
conditions of the survey. For this survey delay time and
channel width were 50 msec and 100 msec respectively. Data for
- 6 -MPH
several of the channels was recorded but it was found that the
10th channel provided the best quality data. Use of the 10th
channel effectively eliminates inductive electromagnetic
effects which may be present in the earlier channels.
The dipole-dipole electrode array with an electrode spacing (a)
of 200 feet expanded through four separations (n - 1-4) was
used for the survey. Initially, an electrode spacing of 100
feet was used to provide adequate resolution of the narrow,
less than 100 foot wide target expected. However, the
electrode spacing was increased to 200 feet when it was found
that the 100 foot electrode spacing did not provide adequate
penetration. The electrode spacing used for the detailed
surveys varied depending on the conditions encountered.

3.0 PRESENTATION OF RESULTS
The results of the survey are displayed in pseudosection format
showing apparent resistivity in ohm-ra and chargeability in
msec. Contour are at semi-logrithmic intervals because of the
wide range, in particular in the resistivity results, in the
recorded data. Plotting of the data follows the usual
procedure, that is half way betwen the two extreme electrodes
at a depth determined by 45* diagonals drawn from the centre of
the dipoles as shown in Figure 3.
Plotting the data in this manner builds up a vertical section
of data points which represent increasing depth of exploration
with increasing n. The term "pseudosection" is used because
the plotted depth does not necessarily represent the actual
depth at which the measurement was made. The actual depth of
the measurement depends on the geoelectric properties of the
ground.
The pseudosections are plotted so that 1" * the electrode
spacing, therefore scales vary accordingly, as follows: a *
100 feet, 1:1200; a * 200 feet, 1:2400; a - 300 feet, 1:3600;
and a * 400 feet, 1:4800.
The results are also compiled on a plan map to show the spacial
distribution of the coverage affected and to allow correlation
with the results of other geotechnical work.

4.0 RESULTS AND DISCUSSION
4.1 Introduction
An interpretation of the results of the surveys is
displayed below the data on the pseudosections. The
extent and position of the cause of anomalies recorded are
illustrated by a 'bar 1 and identified numerically. The
interpretation also displays prominent resistivity
boundaries and contacts. Locations of the anomalies are
also shown on a plan compilation map (Nap 1) to illustrate
their spatial distribution and to facilitate correlation
with other geotechnical information.
Anomalies outlined are discussed on a property basis in
section 4.3 so that the information can be exerpted, if
necessary, for inclusion in geotechnical reports on
individual properties.
4.2 General Considerations
Noisy electrical conditions encountered during the course
of the survey account for the large number of negative
chargeabilities recorded. Collection of the channel 10
information effectively eliminated noise generated by
electromagnetic coupling expected in low resistivity
environments such as those encountered in the area. The
noise appeared to affect all of the receiver channels and
- 10 -
therefore was probably caused by atmospheric disturbances
and/or electrical interference from other induced polari
zation surveys that were in progress in the area at the
time of the work* The noise, however, does not appear to
have been detrimental to the quality of the survey since
anomalous conditions in the results are readily identi
fied. A number of other negative chargeabilities
particularly those associated with rapid spacial and
amplitude changes in apparent resistivity are theoretical
ly acceptable.
Large parts of the survey remained ineffective despite
increasing the electrode spacing from 100 feet to 200 feet
because of thick, moderately conductive overburden
conditions in the area. Areas where the survey was
ineffective are identified on the pseudosections and the
plan map of the survey. To improve the effectiveness of
the survey, the electrode spacing and/or the number of
separations recorded would have to be increased. However,
increasing the electrode spacing decreases the ability of
the survey to resolve narrow targets and employing larger
separations without increasing transmitter current output
may reduce the signal strength to levels where reliable
data cannot be acquired.
MPH
The calculated response expected at n - 4 for a dipole-
dipole electrode array with an electrode spacing of 300
feet over a geo-electrical section with the following
typical parameters:
overburden thickness: 300 feet
target width: 100 feet
overburden/bedrock resistivity contrast: 10
overburden IP effect: O msec
bedrock IP effect: 1 msec
target IP effect: 10 msec
consists of a background of 0.1 msec and an anomaly over
the target of 0.15 msec. Given the electrical inhomoge
neity normally encountered in field conditions, this weak
anomaly is probably not detectable.
VLF-EM conductors detected by previous surveys on the
properties are located on the pseudosections. None of
these conductors appear to be caused by features of
possible economic importance. Most of the conductors
occur at contacts between high and low resistivities which
reflect the contact between bedrock ridges and over
burden. Others occur in areas where large contrasts in
resistivities which probably reflect contacts between
stratigraphic units were recorded.
f r i \ -\.
,MPH- 12 -
Areas where high resistivities were recorded generally
coincide with topographic highs and reflect outcropping or
shallow subcropping bedrock. Variations in resistivity
within these highs are probably related to changes in
lithologies which may be assist geological mapping.
Identification of all of the resistivity units is beyond
the scope of this evaluation which is principally directed
toward anomaly identification and may in fact be wasteful
because of the reconnaissance nature of roost of the
survey.
The major high voltage power line which crosses the area
caused interference in the results. The interference
extended for one or two electrode spacings near the power
line. Other but less severe electrical interference was
experienced in the vicinity of Highway 17 and the CPR
railway track which cross the area.
Physiographic features such as the Black River and several
lakes in the area interrupted the continuity of the survey
lines and interfered with the survey coverage. It is
possible to survey uninterrupted across bodies of water in
the summer time but with attendant logistically difficulty
and time consumption. In areas where continuous coverage
across bodies of water is necessary, it may be prudent to
delay the work until winter months.

4.3.5 Tuscaloosa Oil and Gas Ltd.
Anomaly 1: Line 36+OOW, 103+OOS - 107+OOS
Anomaly 1 is a variable chargeability response caused by a
400 foot wide body associated with a zone of high resist
ivity. The resistivity high reflects near outcropping to
outcropping bedrock ridge which is flanked by thick low
resistivity overburden. The chargeability anomaly
probably reflects a sulphide rich facies within the
bedrock rather than an isolated sulphide body. Elsewhere
on the line, particularly north of 99+OOS the overburden
is too thick for effective penetration by the survey.
f / /i s \ -(MPH^^^
Anomaly 2: Line 68+OOW, 113+OOS - ?
Anomaly 2 is identical in character to anomaly 1. Evi
dence from regional geological mapping and a magnetic
survey conducted on the property indicates that it occurs
in basic volcanic rocks. The belt of favourable volco-
clastic sedimentary rocks north of the basic volcanics was
not effectively evaluated because overburden thickness
exceeds the depth of penetration of the survey conducted.
Anomaly 3: Line 88+OOE, 119+OOS - 135+OOS
Anomaly 3 is similar to anomalies 1 and 2 and therefore
does not constitute a favourable target with respect to
gold mineralization at this time. The results of the
- 25 -
MPH
resistivity survey conducted indicate that bedrock
outcrops or suboutcrops in the area so that surface
exploration methods such as prospecting and/or geochemical
surveys might be effective in evaluating the area. Target
in the area would be a massive sulphide situation rather
than volcano-clastic sedimentary rock hosted gold
situation like the Heralo gold deposits.
Anomaly 4: Line 88+OOE, 97+OOS - 99+OOS
Anomaly 4 reflects a questionable 3 reading anomaly
recorded in an area of low resistivity which reflects
thick overburden conditions. The anomaly does not appear
to be a bedrock response.
- 35 -MPH
5.0 CONCLUSIONS AND RECOMMENDATIONS
The induced polarization surveys detected a number of anomalies
on the properties. Most of the anomalies are attributed to
lithological responses rather than discrete sulphide occur
rences. A number of the anomalies are spurious, occurring in
areas where the survey was ineffective because of thick
overburden conditions.
Valid anomalies of possible economic interest occur on several
of the properties as listed below:
Property
Triple Crown Resources Ltd.
Laco Resources Limited
Devonian Resources Ltd.
Southern Union Resources Ltd.
Anomaly
2/5 and possibly 4
2 and 3
1 and 2
1, possibly others
Detailed surveys on some of these features was done at the time
of the initial coverage. Additional detailing where warranted
is recommended in section 4.3. Geological mapping, prospecting
and geochemical surveys in the vicinity of these anomalies are
recommended to assess their economic potential.
Thick overburden cover over large parts of the area reduced the
effectiveness of the survey. Parts of the area, particularly
( -l'*l those where encouragement has been received from other
geotechnical evidence, could be resurveyed using an electrode
l spacing larger than the 200 foot electrode spacing used for the
survey. It is cautioned, however, that a survey with a larger
electrode spacing, say 300 feet or 400 feet, may be ineffective
ft in resolving the narrow target expected in the area.

INTRODUCTION
The following report deals with a group of mineral
claims owned by Tuscaloosa Oil S Gas Inc. in the vicinity of Hemlo, Ontario, west of the gold occurrence of Corona Resources Ltd., presently being delineated by diamond drilling and readied for
a feasibility study in conjunction with Teck Exploration Ltd.. Existing evidence indicates that the subject property is underlain in part by a similar assemblage.of volcanic rocks found near the Corona Resources Ltd. occrrence. A previous geophysical survey
over the subjects property was carried out by Noranda Mines Ltd. in 1975, but since that time no further work was carried out over the Tuscaloosa property.
This report reviews the results of the earlier mineral
exploration recorded in the general Hemlo area, particularly on Corona's property for which the greatest amount of information is available and for which the writer was responsible for the supervision and direction for the recent exploration of said
^ property in the calender year of 1981.This report is based on an examination of the Tuscaloosa
Oil and Gas Inc. property and an intimate knowledge of Corona
Resources Ltd. gold occurrence. Numerous geological traverses in the fall of 1981 reviewing the Hemlo volcanic belt, supple
mented by a study of assessment work reports on file at the Ministry of Natural Resources in Thunder Bay and personal files
have been reviewed and studied for the Tuscaloosa Oil ft Gas Inc. report.
An initial two phase exploration program on the Tuscaloosa claim group is proposed herein to explore for zones
of gold and base metal mineralization and generally to assess the mineral potential of the property.

of Thunder Bay, Ontario. The claims are illustrated and identified on Plan No. TO-82-3. These claims together with their
next assessment work due dates are listed below:
Claim Numbers Next Assessment Work Due Date
TB632697 to TB632708 (inclusive) October 15, 1982
This claim group is located in the west part of Lecours
township, and its geographic centre lies some 2 miles west of Pringle. Pringle is located along the Canadian Pacific Railway
along the north shore of Lake Superior almost equidistant from
Thunder Bay and Sault Ste. Marie. See Plan No. TO-82-1. Access
to the property is best gained by way of the Trans-Canada Highway ; No. 17 approximately 15 miles east of Marathon. See Plan No. TO-82-2.
cTOPOGRAPHY AND VEGETATION
Personal mapping experience and photogeological studies along the Hemlo volcanic belt indicate to the writer that the topography is generally flat with minor relief 80 feet to 100 feet south of the highway with low rolling hills north-east of the highway. On the Tuscaloosa Oil S Gas Inc. claim group, rock exposures are separated by marshy ravines and sandy knolls. Ground examination and aerial photographic studies of the Tuscaloosa Oil S Gas Inc. property show it to be extensively and densely forested with black spruce, balsam fir and scattered jack pine.
Spotty stands of poplar have been observed. Undergrowth consists of moose maple, tag alder, labrador tea and sphagnum moss.
Overburden consists of unconsolidated Pleistocene detritus, mainly boulder clay, tills, and varved clay deposits
commonly exposed along creeks. Depths of overburden are expected to be variable from s1iallow("5 '-15') near outcrop areas and possibly deep (SO'+J to the north and west portions of the claim group, !
-3-
r The availablity of water on the Tuscaloosa claimgroup is available from north-south running creeks which feed into the Balck River north of the highway and a north-south creek feeding into the Little Black River south of the highway.
HISTORY OF EXPLORATION
The writer has searched the assessment work files in the office of the Resident Geologist, Ontario Ministry of Natural Resources (O.M.N.R.) in Thunder Bay. In 1975, Noranda Mines Ltd. carried out geophysical electromagnetic and magnetometer surveys over the Tuscaloosa claim group. Two Radem V.L.F. conductors were located, one north of the highway on the east end of the property, and a second conductor of good strength south of the highway. This second conductor was followed for 2000 feet, however field examinations by Noranda"s crews interpreted this conductor to be caused by a fault. No further work was done on this property.
s Considering the relative ease of access to the property it is highly probable that at least some cursory examination may have been made, but no records exist to indicate such activity.
Gold was first discovered in the district in the summer of 1945 near Moose Lake some eight and a half (8.5) miles east, by T. Ollmann of Heron Bay on a group of patented claims (The Ollmann- Williams claims). Since that time, a number of companies including Lake Superior Mining Corporation, Teck Exploration Company Limited, Ardel Explorations Limited, Noranda Explorations Ltd. and most recently, Corona Resources Ltd., have conducted exploration programs, including diamond drilling, geophysics, geological mapping and geochemistry. By December 31, 1981, Corona Resources Ltd. had completed 175 drill holes and outlined two auriferous pyritic zones enclosed in an altered package of siliceous- sericitic-agglomeritic tuff. From January of 1982, Teck Corporation Ltd. optioned the Corona Resources Ltd. property and is currently carrying out a feasibility study to .place the Corona property \int.o
( production. Roughly one million (1,000,000) tons of drill-indicated
-4-
(gold-bearing material has been outlined with a grade better than
0.20 oz. Au. per ton.
In 1978, during his mapping of the Hemlo area for the
O.M.N.R., T.L. Muir (Open File Report 5280) collected a number
of grab samples of rusty pyroclastic material along Highway 17
roughly 2 miles west of the Corona Resources Ltd. property
and had them analyzed for a variety of metals. One sample assayed
0.32 oz. per ton Au., and 0.48 oz. per ton Ag..
REGIONAL GEOLOGY
C
(
The general geology of the Hemlo area is shown on
Map 2220, "Manitouwadge-Wawa Sheet" published in 1972, scale one
inch to two miles (O.M.N.R). In 1978 the area was mapped by
Muir and Lafleur and is shown on O.M.N.R Map 2452 scale l inch
to % mile, and described in O.M.N.R. Open File Report (O.F.R.)
5280.
The dominant rock types appear to be a series of
conformably intercalated volcanic formations, as follows:
1. Mafic metavolcanics consisting of flows and
their associated pyroclastic units.2. Intermediate to Felsic Metavolcanics,
mainly pyroclastic.
3. Metasedimentary units consisting of siltstones,
argillites, laminated clastic wackes, etc.,
mainly derived from volcanic source areas.
Medium to high grade metamorphism has sufficiently
recrystallized these formations and as a result reliable top
determinations are difficult to identify. In general the rock
formations strike east-west and dip steeply to the north. Four
identifiable intermediate to felsic intrusive plutons have been
named by Muir (et al), the Cedar Lake Pluton, Heron Bay Pluton,Gowan Lake Pluton, and the Pukaskwa Gneissic Complex. These v i i plutons have played a major part in the regional metamorphic!
-5-
finger printing of the volcanic suite as well as locally deforming and fracturing the volcanics with numerous more or less pronounced topographical lineaments criss-crossing the region in a variety of directions. One of these major lineaments has been called locally as the "Hemlo Fault" or "Lake Superior Shear Zone". The portion of the "Lake Superior Shear Zone" has been delineated by diamond drilling on the Corona Resources Ltd. property and has been identified as an altered siliceous, sericitized, tuffaceous agglomerate horizon containing auriferous pyrite zones, with minor amounts of fuchsite, tourmaline and molybdenite and trace amounts of sphalerite, chalcopyrite and native gold.
Feldspar porphyry and quartz porphyry sill-like masses intrude the volcanic and sedimentary belt locally and quartz diabase mafic intrusives cross-cut all units in a north-south pattern.
The aeromagnetic maps of the region define the general position and trend of the metasedimentary-volcanic belts and distinguish them from the felsic plutons.
LOCAL GEOLOGY AND MINERALIZATION
The property of Tuscaloosa Oil and Gas Inc., in the Hemlo area, i s underlain by a generally east-west trending sequence of mafic metavolcanic flows and pyroclastic units. Noranda Mines Ltd. indicated a narrow discontinuous lens of quartz-biotite schist south of the highway and parallel to their V.L.F. conductor. The formations are generally vertical to steeply dipping north. A diabase dyke runs north-south across the Tuscaloosa claim group. Because of the apucity of the outcrops north of the highway it is possible that felsic flows and related pyroclastics may be present.
The Heron Bay Felsic Pluton is in contact within the south east boundary of the claim group.

CONCLUSIONS
Recent exploration on the Corona Resources Ltd.
property in the Hemlo area has been successful in delineating
auriferous pyrite of a stratbound nature enclosed within volcaniclastic sediments. Similar gold bearing occurrences within this same unit have been sampled and assayed elsewhere in the Hemlo area by T.L. Muir (O.M.N.R.) which may be evidence of other zones of auriferous sulphide mineralization in the Hemlo area.
Rock formations underlying the Tuscaloosa Oil k Gas Inc.
property should be re-examined to look for gold bearing units similar to those mentioned above.
RECOMMENDATIONS
It is recommended on the basis of the successful technical work carried out by Corona Resources Ltd., that the
Hemlo property of Tuscaloose Oil k Gas Inc. in the District of
Thunder Bay, Ontario, be explored for gold deposits by means of the following techniques:
1. Establish a control grid of cut picket lines over the claim group from which geophysical and geological surveys
would be guided. Traverse lines to be cut on 400 foot intervals at right angles from a surveyed base-line running 085 0 E and survey stations established at 100 foot intervals.
2. Electromagnetic V.L.F. EM-16 survey and magnetometer survey over the control grid to re-establish previous conductors outlined by Noranda in 1975.
3. Detailed geological mapping of the claim group at a scale of l inch to 400 feet. Sampling of all outcrops indicating silicification, sulphide mineralization, and other alteration minerals (Fuchsite, tourmaline, sericite, etc.) for gold and other base metals.
A. Provisions for diamond drilling of promising geological structures and geophysical anomalies as outlined by the above methods.
s
-7-
ESTIMATE OF COSTS
The estimate of costs is based on a first phase exploration program consisting essentially of geophysical and geological
mapping and an allowance for a limited amount of sampling and
trenching. Contingent on favourable results from the above first phase, the second phase costs would consists essentially of diamond drilling, assaying and supervision.
