GEOLOGICAL REPORT CANABEC EXPLORATIONS LIMITED

RABAZO AND NAVEAU TOWNSHIPS, ONTARIO

NUMMARY

The property consists of twenty-five contiguous

unpatented mining claims bordering on Rabazo and Naveau Town

ships, in the District of Algoma, Ontario.

These claims cover several known gold occurrences

located southeast of the Townsite of Wawa, Ontario. Wawa has

a well documented history as a gold camp, having at least a

dozen or more past producing gold occurrences within the area.

One such producer, known as the Norwalk Mine, is located on

this property.

I feel that the previous work on this property stopped

short and dicJ not indicate the true potential of the mineral

ization as seen in the surface exposures over the whole of the

property. Some of these mineralized occurrences were resampled

and the resultant assays indicated good values in gold in

competent geological rock units.

Several showings had very little previous work, some

of which included surface trenching, pitting and minor adit

drifting done prior to 1940. The only evidence of drilling work

was noted a few hundred feet southwest of the Norwalk shaft,

paralleling several major quartz vein occurrences. The assess

ment records indicate that some 1,500 feet of diamond drilling

had been carried out prior to 1963 with some assays in gold.

ifer,V/:''fjC??' f .'''.,c. w. ARCHIBALD

In all, eighteen claims were surveyed at 200 foot

line intervals. The results of this survey indicated a

noticeable pattern to the mineralized showings which sub-

paralleled the general strike of the geological units.

(See Map) .

From these results and the anomalous trends pro

duced by the geophysical surveys, there are several areas

outlined which may hold significant gold and base metal

potential. These would have to be tested further by diamond

drilling as most of the surface expressions are poorly exposed

or covered by overburden.

PROP.ERTY

The property consists of twenty-five contiguous

mining claims in the District of Algoma, Ontario. The claims

are numbered as follows:

SSM 497993, 466678, 502010 to 502013 inclusive,SSM 521218 to 521225 inclusiveSSM 467838 and 467839SSM 467867 to 467872 inclusive, in Rabazo Township.

SSM 466676 and 466677 in Naveau Township.

Twenty claims are located along the northeast side

of Rabazo Township (M. 1556) and five are within Naveau Town

ship (M. 1546) with the Township line as a common border.

ACCESS^ and TOPOGRAPH.Y

The property is located in the District of Algoma

approximately six miles south of Wawa, Ontario, just off the

Trans-Canada Highway 17. Wawa lies approximately 140 miles

north of Sault Ste. Marie and can be reached by daily air

service or automobile.

The property is bisected by an all-weather access road

which connects the High Palls Dam project with the Trans-Canada

Highway 17. It is approximately three miles east of this High

way and covers about 1,000 acres of ground.

The twenty-five contiguous claims are more than half

covered by glacial-fluvial overburden. The relief is generally

low and the ground swampy to the oast but it is cut extensively

* C W. ARCHIBALD

by ravines and drainage channels along the western boundary.

This ground occupies part of the old Michipicotan River basin

and erosion has cut ravines to depths in excess of one-hundred

feet in many places.

Outcrops cover approximately fifty percent of the

property and rise steeply in a northeast to southwest direction.

Two high-voltage transmission lines cross the property

in a northwest to southeasterly direction. The major power line

carries some 250,000 volts and cuts through the noi thorn boundary

of this claim group. The other set of lines carry power locally

from the High Falls Dam to the Wawa Townsite.

GEOLOGY

The area around Wawa consists of a series of inter

mediate to basic volcanic flows interbedded with metasediments

and intruded by later granitic, alkalic and ultramafic rock types,

The Wawa area is well known for its high mineral pot

ential having many well documented occurrences of gold and base

metals such as copper, lead, zinc, molybdenite and nickel. Most

noteworthy are the vast strataform deposits of siderite and

hematite iron formations owned by Algoma Steel.

The property is underlain by undifferentiated mafic

to felsic metavolcanics and supposedly Archean roetasedinents.

3 C. W. ARCHIBALD

The O.D.M. Preliminary Geological Map (P. 640) indicates the

presence of several major units in contact within the boundary

of the property.

The major rock units encountered include intermediate

to basic volcanics grading from andesite to dacite in composition

and acid volcanics which graded from a trachyte to an inter

mediate trachy-andesite and often varied in composition and

colour within a few feet. Intruded into these units were

assemblages of gabbros, quartz diorites, quartz porphyry and

a feldspar porphyritic syenite to granite.

The sedimentary units depicted on the O.D.M. Sheet

(P. 640) appeared as porphyritic quartzites, quartz arenites

or biotite rich gneisses. These units often occurred inter

calated with the metavolcanic and intrusive units and were

very difficult to distinguish clearly due to the degree of

local metamorphism and subtle gradational changes. Very little

sedimentary structure was evident.

The general strike of the units was northwest to

southeast with a strong lineation determined by the flow struc

tures, pyroclastic fragments and alteration within the indiv

idual rock units.

The metavolcanic units occupy most of the western

portion of the property with increasing ultramafic content

occuring closer to the major contact with the coarse grained

w . C. W. ARCHIBALD

granitic syenite intrusion along the eastern border of the

property. Localized lenses of gabbro, hornblende amphibolite

and quartz-eye porphyry were observed east of the High Falls

road. Later intrusions of diabase and quartz veins and

stringers are also evident. Much of the quartz consists of

a massive, milky-white to clear variety.

The gold mineralization occurs within, or in contact

with, many of these quartz stringers or vein occurrences,

especially where pyrite is the mineralization associated with

the quartz. Often the pyrite is weathered and rusty and may

account for some localized enrichment of the gold values.

Several linear massive sulphide occurrences were also

observed. These follow the trend of the geological units and

appear to be associated with basic metavolcanic and ultramafic

rock types. The major accessory minerals were pyrrhotite,

pyrite and minor chalcopyrite, graphite and quartz. Sampling

at several locations indicated some values in gold which lends

strength to the similar geological association found at the

Centennial Gold Mine, just a half-mile to the east.

Several good targets have been defined through geo

logical extrapolation and geophysical anomalies. These will

be tested by diamond drilling to verify any mineralization

at depth.

ECONOMIC GEOLOGY

Located within the boundary of this property are

several old shaft? and adits that were part of the original

discoveries in the Wawa Area. These include the Norwalk Mine,

a past producer, the Fred C. Shaft, the Stenbaugh Showing and

several other minor gold occurrences. Very few records of the

past work, production or underground development exist.

References indicated that some gold production was

obtained from a small mill located at the site of the Norwalk

Shaft but no details as to ore grade, tonnage or underground

geology are available. This work was carried out during the

1920's and early 1930's with very little work done since thatO

time. Inspection of the mine site and waste dump indicated

a very small operation. The country rock at the dump consisted

of a green siliceous to sericitized schist fractured and cut

by quartz and calcite vein networks. The shaft was sunk on a

five foot wide splash of rusty quartz cutting a massive quartz

porphyry.

The other showings that were examined on the property

hewed a similarity in geological structure. Most occurred on

or near a zone of shearing or fracturing where quartz and rusty

pyrite mineralization appeared to intrude into zones of struct

ural weakness. These fractures often cut the existing geological

units at some concordant angle but the fr ,jency of these vein

networks appear to be linked to both the structural and geological

trends in the area.

l^'v"- '. :~' ' - ' . C. W. ARCHIBALD'. .W - CONCLUSIONS -----~------

v - . The Wawa area has had a long history as a high pot

ential mineral producer, especially in gold. The accompanying-'

location map shows the spr^ial relationship between this oroperty

to the past producing depoaits and their geological significance.

The latest work in the area by the Ontario Department

of Mines included correlation of all the available geological

data and recent reconnaissance napping. The results were pub

lished in 1971 with the printing of a new geological map numbered

P. 640, which indicated a different geological picture to the

previous compilation by Goodwin in 1963.

A In view of the new geological relationship and the9

spatial relationship between felsic, acid metavolcanics and their

proximity to granitic and carbonatite intrusive bodies, the

mineralogical and orogenesis takes on a new perspective.

The occurrences of gold in the area has a definite

relationship to certain rock units which includes both the felsic

metavolcanics and intrusive units found on the property. The vein

occurrences vary from less than an inch to several feet in width

and are often discontinuous in sise and length. Several showings

occur close to widenings or splashes in the quartz. These veins

appear to cut the existing units often at varying angles. Some

traverse local faulting and fracturing but do tend to widen at

these junctures, lending weight to the idea that they were con

temporaneous to structural activity.

C. W. ARCHIBALD' 'RECOMMENDATIONS~~" ~ ------

The geological survey included mapping of all the

existing outcrops, trenches, pits and topography. Samples

were taken at all mineralized locations and an effort was

made to determine the extent and directions of the mineral

ization with respect to the old gold showings and new occur-

rjnces.

At this close interval, the detailed geological

compilation gave enough information to determine a general

pattern to the geological units as to strike, dip and structure,

and to what rock units the gold mineralization was most closely

associated. It also revealed the relationship of the gold to

accessory mineralization such as pyrite, which in turn provides

a useful exploration tool for sampling and mapping.
