m SUMMARY
A gold exploration programme involving 4,489 ft. of diamond dril-
I ling in 13 holes has been completed on a 1,320 acre property in
Bryce Township, northeastern Ontario, for Windjammer Power and Gas
l Ltd. and Yvanex Developments Limited.
The claims encompass the former Briscoe-Bryce No. l Vein Zone gold
l prospect which saw limited production in the I960 1 s. The rock
that was milled reportedly graded in the 0.5 to 0.6 oz Au per ton
l range. The gold occurs in quartz-pyrite-chalcopyrite vein
m material within a steeply dipping shear structure which is appro
ximately conformable with host intermediate volcaniclastics. The
l shear is a strong, through-going feature which has been defined
over a strike length in excess of 850 m by the previous and pre-
I sent drilling and is open in both directions and to depth.
Pre-1940 surface trenching indicated three surface oreshoots as

The 1981 drilling was carried out east of the old workings in a
previously relatively unexplored area. The grades in the 1981
drilling in this eastern sector are, in general, significantly
better than grades in the previous drilling under the old surface
workings.

The No. l or "main" vein shows a distinct stratigraphic control
being located in a chloritic tuffaceous unit in the basal portion
of a feldspar porphyritic crystal tuff which in turn is located
between two thick units of coarse intermediate volcanic breccia.

Gold values are closely restricted to a narrow, generally central,
quartz-sulphide vein within the shear. These high grade sections
often assay more than l oz Au per ton. Subordinate veins on
either side or sections of mineralized shear material generally do
not carry gold values.
Four holes were drilled elsewhere on the property to test geo
physical targets. No gold intersections of potential economic
significance were recorded. These holes were technically success
ful, however, in that the cause of the geophysical anomalies has
been explained in every case.
Several old trenches excavated by previous workers were located
and re-sampled. The trenches invariably expose quartz-pyrites
chalcopyrite vein material in chloritic shear zones. The veins
are generally very narrow and irregular. Values of up to 0.30 oz
Au per ton were recorded in selected grab samples. More syste
matic chip samples across vein structures returned low values.
Although none of the trench areas appear to have any immediate
economic significance, they do emphasize the widespread distri
bution of gold mineralization in the property area.
It is concluded that the No. l Vein Zone has potential to host an
economic tonnage of gold-bearing rock. The area between present
sections 0+00 and 5+OOmE is of greatest interest based on the work
to date. Potential grades of 0.20 oz Au per ton over mining
widths of 5 ft. are indicated.
A programme of additional diamond drilling totalling 7,100 ft is
recommended to further develop the economic potential of the No. l
Vein Zone with a minor amount of footage devoted to testing two

These surface zones are located between present baseline co

A total of approximately 6,000 ft. of various sizes
drill coring has been carried out on the No. 1 Vein
1930 and 1975 by previous workers including Noranda
Mining Projects of Canada Ltd., Briscoe-Bryce Mines
Mining and Exploration Ltd. and the Rip Van Winkel

All of this
l lm drilling has been relatively shallow with vein intersections
generally in the range of 50 to 100 ft (15 to 30 ra) vertically
l below surface.
l
l
Previous drilling between 0+SOmW to O+TSmE established that the
mineralized structure here continues to depth with generally low
gold values present. The best value recorded was 0.53 o z Au per
l ton over 0.3 m (previous hole MP-6, Map 3c).
l
l
Drilling immediately to the east of the above returned higher gold
values and substantially increased amounts of vein material within
the shear structure. The zone appears to dip approximately 75 e S
l in this region relative to a more vertical dip in the area of the
headframe. A previous hole in the vicinity of present line 1+OOmE
" returned 0.22 oz Au per ton over 1.0 meters (Noranda hole N-l).
B Another hole immediately to the east returned a 5.5 m section of
shearing and vein material with one section averaging 0.06 oz Au
l over 1.95 m. Contained within this was a 0.3 m section which
returned 0.32 oz Au per ton.
l A previous hole on the vein at present 2*75mE intersected a 0.8 m
section which returned 0.51 oz Au. A hole 60 m east of the above
g intersected the vein and returned an assay of 0.15 oz Au over
. 0.8 m.

l
llm Other known and reported gold prospects within the present pro
perty include the Contact Zone, South Zone/ J.R. Campbell occur-
I rences and the H. Briscoe Jr. (Honeymoon Lake) occurrence.
l
l
A 1980 programme completed on behalf of Windjammer-Yvanex con
sisted of geological reconnaissance and surface trenching and
sampling along with a programme of linecutting and ground geo-
I physical surveying (magnetics, VLF-EM, Induced Polarization).
l
l
The 1980 trenching and sampling on the No. l Vein generally con
firmed previously indicated gold tenors. A systematic chip sample
in the shaft beneath the headframe on the previous "C" zone re-
I turned 0.414 oz Au per ton over 0.7 m. Six selected grab samples
returned 0.270, 0.184, 0.149, 0.254 and 0.02 oz Au per ton. A
l
3216 Ib bulk sample taken from the shaft by previous operators
reportedly averaged 0.38 oz Au, 1.10 oz Ag per ton.
l A 3.0 m chip sample taken in 1980 across a trench in the previous
"A" surface zone returned 0.204 oz Au per ton. A chip sample
B across a 0.3 m massive pyrite band in the trench returned 1.04 oz
U Au. A 2.6 m sample across the vein in the existing shaft in the
"A" zone returned 0.270 oz Au per ton. A previous 1990 Ib bulk
l sample from the shaft reportedly averaged 0.76 oz Au per ton.

Geophysically, there is a complex and very low amplitude IP res
ponse locally associated with the No. l Vein Zone. The PFE (per-
I cent frequency effect) signature improves to the east and to
depth. The host shear zone appears on some lines as a distinct
l anomaly in the IP resistivity data. The anomaly is indicative of
m a vertical source which extends to depth. There is a flanking
VLF-EM response associated with part of the No. l Vein Zone.
l There is no magnetic signature associated with the No. l Vein.
m Induced Polarization surveying over the Contact Zone to the north
M o f the No. l Vein Zone indicates a strong resistivity-PFE anomaly.
This zone represents the contact between Catherine Group basalts
l to the north and Skead Group volcaniclastics to the south. The IP
anomalies probably relate to pyrite-chalcopyrite mineralization
known to be present in the interflow sedimentary Contact Zone.
B There is a strong VLF response along the Contact Zone. Previous
drilling encountered low Au values.
lIt was concluded that results of the above exploration were suf-
ficiently encouraging to warrant an aggressive diamond drill
l evaluation of the property. A programme of 2500 ft of N-size dia
mond drilling in 9 holes, which subsequently became 4500 ft in 13
l holes, was therefore recommended with drilling to commence in
early April of 1981. The above drilling was completed and is the
" subject of this report.

115.0 DIAMOND DRILLING PROGRAMME - 1981
l 5.1 Drilling
Drilling operations were carried out by Barron Diamond Dril
ling Ltd. of Haileybury, Ontario.
A total of 4,489 ft. of NQ drilling was completed in 14
l holes. One of the holes, No. 12, was lost in overburden and
had to be re-drilled as hole 12A so that a total of 13 holes
l was actually completed.
Core recovery was, in general, excellent. Recovery was poor
l in isolated instances where the rocks were heavily fractured
and sheared. Recovery in the No. l Vein Zone was very good.
l A few instances of locally poor recovery are a reflection of
open cavities in the vein rather than actual loss of core.
All drilling was carried out with a Longyear 38 machine sup
ported by a small tractor.
Drilling operations were completed in the period April 9 to
July 9, 1981.
Drill core is presently being stored in core racks in a cabin
I X on the property.
l lM The drilling programme was managed by MPH Consulting Limited
of Toronto on behalf of Windjammer and Yvanex.
l5.2 Assaying
l All assaying and analytical work was carried out by Swastika
m Laboratories Limited of Swastika, Ontario.
l Gold and silver determinations were made by fire assay tech
niques. Copper, along with occasional Pb and Zn, were deter-
I mined by atomic absorption.
Intersections of vein material were sampled in very short
l lengths, generally l ft. Such samples were completely pul
verized in the laboratory and two cuts taken for fire assay.
l
This minimized the effects of any erratic coarse gold and
provided for very uniform and representative assay results.
l Any core sections which appeared to have any Au potential
were split and assayed.
B Unused sample material has been collected from Swastika and
is being stored for possible future use.
lThe entire assay results for the 1981 programme are presented
l as Appendix A.

A minor progranune of trench re-sampling and geological recon-
l naissance was carried out in conjunction with the drilling.

6.O GEOLOGY
6.1 General
The property straddles the boundary between the Catherine
j Group and the Skead Group of earliest Precambrian (Archean)
mm metavolcanics. The Catherine Group is comprised of Mg-rich
and Fe-rich tholeiitic basalt flows with Fe-rich tholeiites
l predominating at the top of the group.
l The Skead Group consists mainly of massive calc-alkaline vol-
M canic fragmental rocks of basalt, andesite, dacite and rhyo-
lite composition. Some flows are present in the group. The
l fragmental rocks range from crystal tuff to tuff-breccia and
flow breccia. The coarser fragmental rocks contain a wide
l variety of felsic fragments. The main source of the volcanic
M ejecta appears to have been a large volcanic centre in Skead
Township to the north of the present property area. Recent
l government mapping has defined an additional volcanic centre
in the vicinity of Heather Lake immediately south of the
l present ground.
The contact between these two formations, the "Contact Zone"
l of previous workers, crosses the property in the vicinity of
detail baseline 4+OON. Present and previous work on the
l "Contact Zone" indicates that there is a major unit of inter-
l
l
l l j flow metasediments consisting of laminated cherty and
tuffaceous rocks containing pyrite and chalcopyrite sepa-
I rating the two formations.
m Porphyry and lamprophyre dykes intrude the volcanic rocks.
m An elliptical stock of feldspar porphyry containing several
gold veins is centered 2 miles east of the property. Another
l porphyry body located by recent government mapping occurs on
the west portion of the present property immediately south of
l Honeymoon Lake.
The Round Lake granitic batholith occurs directly north of
l the property area.
B Rock units on the property strike east-northeast and are
B steeply to vertically dipping. There is no evidence of any
fold closures in the immediate property area. Stratigraphic
l tops in the area are indicated to be to the southeast.
B The property is located between two major regional faults
H striking N40 0W, the Cross Lake Fault and the Montreal River
Fault. A study of the fracture pattern in Bryce Township in-
I dicates 3 prominent fracture directions; northwest, northeast
to east-northeast and north-south. A major northeast-
H trending airphotographic linear herein termed the "Sunday
l
l
16
Creek Linear" passes to the south of the property. These
fractures are important in that most of the gold minera
lization recognized to date in the area is controlled
by one of the above fracture directions, e.g. the Briscoe-
Bryce No. l Vein Zone along an east-northeast structure.
6.2 Mineralization
A 1941 Ontario Department of Mines report describes 34 gold
prospects in the Bryce-Robillard area (Moorhouse, 1941).
This author classified the more important gold occurrences
into a number of types according to structure and minera
lization as follows:
a) mineralized shear zones
b) mineralized porphyries
c) mineralized joints and shear zones in granite
The first group consists of deposits that occur ins
1) northeast-trending zones? (2) north-south zones and
3) northwest-trending zones. In the northeast-trending
zones, three types were recognized, i) those mineralized
with disseminated pyrite and other sulphides with quartz,
ii) those mineralized with massive pyrite * quartz and
iii) those mineralized with pyrite accompanied by chrome,
mica, and quartz.
17
The Briscoe-Bryce No. l Vein Zone would be an excellent
example of a mineralized shear zone of type ii).
There is an additional and very important type of gold occur
rence in the area, namely gold associated with laminated in
terflow sedimentary horizons consisting of cherty and tuf
faceous material containing stratiform laminae and dis
seminations and stringers of pyrite and chalcopyrite. These
units are typically sheared and show varying degrees of seri
citization, carbonatization and chloritization. This variety
would be analogous to Moorhouse's "mineralized shear zones of
type a-1". The Contact Zone on the Briscoe-Bryce property
and reported occurrences on the J.R. Campbell property would
be of this type. Much of the ore from some of the world's
major gold deposits such as Amoco's Detour deposit and the
Dome Mine at Timmins is or will be derived from orebodies of
this type.
The only serious attempt at commercial gold production in the
area was from the Briscoe-Bryce No. l Vein Zone. There are
no accurate records of the work but, according to Harold
Briscoe Sr., a total of approximately 100 tons of ore was
milled in a 60-75 ton per day mill installed on the property
in the mid 1960"s. The rock milled was taken from the dec
line and No. l and No. 2 shafts on the "A" and "C" zones res-
l lm pectively. Average grade of the mill feed is reported to
have been in the 0.5 to 0.6 oz per ton range. The operation
l appears to have been relatively crude. In any event, the
mill burned down in 1967 "before steady production had been
l achieved".

7.0 DESCRIPTION OF PROPERTY GOLD OCCURRENCES
There are several known and reported gold occurrences within the
confines of the present property area, the most important of which
are discussed following:
7.1 Contact Zone
During the early stages of prospecting in Bryce and Tudhope
Townships in the 1930's, considerable work was expended in
attempting to trench and sample a pyritic, carbonatized,
sericitized, silicified, sheared band of tuffaceous sedi
ments which occurs at the contact between the Catherine and
Skead Groups. This contact was apparently only exposed by
trenching in two locations along a strike length of over 3
miles. One of these trench localities was on claim T 25697,
now part of the property described herein. This so-called
"Bailey T-trench" was excavated in the 1930's and reportedly
returned 0.114 oz per ton Au across a width of 60 ft.
Five short holes were drilled in the T-trench area in 1939.
There were no Au values in the core above 0.02 oz per ton
although sludge samples reportedly returned up to 8 oz Au per
ton.
20
In 1967, two diamond drill holes were drilled 2100 ft. west-
southwest of Bailey's T-trench for Trihope Mining and
Exploration Co. to investigate a VLP-EM conductor on the
"Contact Zone". Although no ore values were reported, the
drilling did intersect bands of interflow tuffaceous and
cherty sediments with pyrite and up to ^ chalcopyrite.
In 1975, the Rip Van Winkel Syndicate investigated the zone
in the immediate area of the old Bailey Trench with a total
of 328.6 ft in two diamond drill holes. Both holes inter
sected the silicified, sericitized, pyritized "Contact Zone"
which varied in width from 13.3 ft. (Hole 1) to 30 ft. (Hole
2). Assay results were "disappointing" with the best value
being 0.03 oz Au over 10 ft.
7.1.1 Sampling - 1980
The Bailey T-trench was located during the 1980 explo
ration programme. An attempt to completely excavate
the old trench with a backhoe was only partially suc
cessful.
A portion of the actual contact zone was exposed im
mediately north of an old, cribbed, water-filled shaft
at the T-junction in the trench. All quartz *
21
sulphide mineralization was blasted and sampled.
There were no gold values of economic significance in
any of the samples with the highest value of 0.03 oz
Au per ton being from a thin massive pyrite band im
mediately adjoining the old shaft. It is probable
that the best mineralization is present at the bottom
of the shaft. This could not be sampled during the
present work as this area of the trench was beyond the
reach of the backhoe.
An additional trench to the north that reached bedrock
likewise failed to return any values of significance.
Although disappointingly low in an economic sense, the
values are in accord with previous drill results and
indicate that this interflow unit is distinctly ano
malous geochemically in gold. Such a unit may have
acted as a source rock or protore for subsequent gold
concentrations in favourable structures elsewhere
along this auriferous sulphidic unit.
The original assay value of 0.114 oz Au over 60 ft in
the Bailey T-trench must be totally discounted. If
real, it is possible that the value represented a sur-
l l l l
l
l
l

face enrichment not representative of the underlying
bedrock.
7.2 Briscoe-Bryce No. l Vein Zone
l The original showing was found by the Briscoe Brothers by
m trenching through clay after they had found mineralized auri
ferous float along the old wagon road in this vicinity in
l 1935. Between 1935 and 1957 much laborious trenching was
done between the present two shafts and eastward by hand,
l horse-drawn scoop or scraper and by drilling and blasting.
m Most of these old trenches reportedly never reached bedrock.
An eastward sloping, 40" decline was sunk at the west end of
l the surface workings (headframe - Map 3c) and a vertical
shaft was sunk and timbered to a depth of 32 ft. toward the
east end of the surface workings, above present hole 81-1.
In his 1941 report, Moorhouse notes that
"......after trenching had exposed the mineralized zonein some 15 pits...sampling indicated an ore shoot 450 ft. long and 3 to 4 ft. wide, averaging 0.20 to 0.28 ounces of gold per ton."
Subsequent workers determined that the surface zone,(between
present 0*25mW and 1+251HE on Map 3c), consisted of 3 indi-
vidual "oreshoots" as follows:
23
"A" Oreshoot - This was exposed on surface for a length of
135 ft. It is reported as averaging 0.29 oz Au per ton over
an average width of 4.0 ft. Mining Projects of Canada Ltd.
subsequently extended this oreshoot an additional 185 ft. to
the east by diamond drilling. Gold values in the drill-
M indicated extension are low being in the 0.04 to 0.06 oz per
ton range. Harold Briscoe Sr. showed the author assay
B results which indicated that a 1990 Ib bulk sample from the
shaft in the "A" zone returned 0.76 oz Au per ton and
B D.40% Cu. There was no silver assay performed.
"B" Oreshoot - This is located immediately west of "A" and is
l reported to average 0.373 oz gold per ton across an average
width of 1.6 ft. for a length of 165 ft.
lB "C" Oreshoot - This is reported as grading 0.194 oz Au per
ton across an average width of 3.0 ft. for a length of 80 ft.
B based on surface sampling. There is an approximately 60 ft.
section of "very low-grade material" separating the "B" and
l "C" oreshoots. A 3216 Ib bulk sample taken from the shaft in
m the "C" oreshoot returned 0.38 oz Au and 1.10 oz Ag per ton
according to old assay results. Additionally, it is reported
l that virtually every round in the decline exposed visible
gold.
l
l
l
l lm 7 .2.1 Sampling - 1980
Considerable difficulty was encountered in reaching
l bedrock with a backhoe in the vicinity of the pre
viously reported "A", "B" and "C" oreshoots. Clay
l
overburden in these areas is deeper than 15 ft., the
maximum penetration capability of the backhoe.
l Sampling at the top of the now filled-in #1 shaft
beneath the headframe appears to confirm previously
l indicated gold tenors. A 0.7 m chip sample across the
m vein exposed on the west wall of the shaft returned
0.414 oz Au per ton. Four selected grab samples re-
I turned 0.270, 0.184, 0.149 and 0.254 oz Au per ton.
Two massive pyrite grab samples from the decline re-
I turned Au values in the 0.02 oz range.
Sampling in the area of the No. 2 shaft on the "A"
l oreshoot (line 1+OOmE) returned the most encouragement
of the programme to date. A 3.0 m chip sample on the
B east wall of trench #5 on the vein at line 1+OOmE
B returned a weighted average of 0.204 oz per ton Au. A
2.6 m chip sample across the west face of the No. 2
l shaft returned a weighted average of 0.270 oz per ton
Au.
l
l
l lm Examination of selected grab sample values from within
the zone strongly suggested that the average grade in
l a bulk sample would be higher, possibly substantially
so, than the previous values. For example, in the
l above trench, the central 1.0 m chip sample returned
m only 0.002 oz Au yet a grab sample, #5, from within
this zone returned 0.63 oz Au per ton. Likewise, the
l northernmost chip sample returned 0.002 oz across
0.5 m yet two grab samples from within this zone
l returned 0.72 oz Au and 1.04 oz Au per ton respec-
m tively. The latter value represents a sample across a
0.3 m massive pyrite pod on the west side of the
l trench.
l Several old trenches excavated by previous workers were
j located and re-sampled during the 1981 drill programme.
The trenches invariably expose quartz-pyrite
l j- chalcopyrite vein material in chloritic shear zones.
The veins are generally very narrow and irregular.
B Values of up to 0.30 oz Au were recorded in selected
B grab samples. More systematic chip samples across the
vein structures returned low values. Although none of
l the trench areas appear to have any immediate economic
significance, they do emphasize the widespread distri-
bution of gold mineralization in the property area.

8.0 DRILL RESULTS - 1981
8.1 Summary
The 1981 drilling on the No. 1 Vein Zone in combination with
previous work has established that the vein extends from at
least 0+SOmW to 8+OOmE, a distance of 850 meters (2800 ft.).
The vein is open in both directions and to depth.
The present drilling was carried out on 100 m centres east of
the old surface workings towards a previously unexplored
area. The grades in the 1981 drilling in this eastern sector
are, in general, significantly better than grades in the
previous drilling under the old workings.
Drill results on the No. 1 Vein Zone are summarized

DESCRIPTION
ANDESITIC TO CHLORITIC CRYSTAL TUFFrelatively massive, featureless, coarse feldspar porphyritic crystaltuff. This material forms the matrix to above unit; contact with abovpyroclastic is marked by a 1 ft band of dark fine grained tuff or mud stone with quartz veining.The crystal tuff unit consists of white plagioclase crystals and da'rkgreen chlorite clots in a greenish chloritic matrix with scatteredquartz eyes. Rock is weakly carbonatized where tested with weak HC1.There is local, trace pyrite and variable hematite mainly on slip andfracture surfaces and in veinlets ± quartz-carbonate. There is anoticeable increase in hematization progressing down the hole.A weak schistosity is present generally at 60" to c. a.The tuff has been finely fractured with clear quartz ± carbonate andhematite forming hairline to 1/2 inch veinlets; one fracture set is at60 8 ro 80" to c. a.No appreciable sulphide association; there is a concentration of sili cification from 144 to 173; this veining is cut by later, thickerveinlets of white quartz, carbonate and hematite.JLby tt: B inch tragment of fine-grained volcanic (? ) showing chillededges against turt with 1* pyrite.175 ft: 2 inch quartz-carbonate-hematite vein zone alona local shearat JL5 0 to c. a.185 ft: 3 inch fraament of fine-grained volcanic.186.5 fti 1 inch vein of whLte quartz at 20" to c. a.209 ft: 1 inch qtz - carb. -hem. vein at 20" to c. a. with one smallcrystal chalcopyrite.221 ft: 1 inch atz-carb-hem vein at O 0 to 20 0 to c. a. as noted^ theseveinlets appear to be later than the foreqroincr fine, clear quartz-hematite filled fracturing.

DESCRIPTION
VEIN ZONE f #2)narrow qtz-py-cpy zones in intermediate tuff; mineralized sections are carbonatizedand show a licrht areenish sericitization/silicification; pyrite often has a coarsegranular fractmental aspect as in previous holes. Discrete mineralized sectionsare as follows :
1/2 in at 254 ft.1/2 in at 254.5 ft.3 in at 255.5 ft.1/2 in at 256.5 ft.1/2 in at 259 ft.
