INTRODUCTION
This report on the evaluation of the McFinley Red Lake Mines shaft area
during 1985 and early 1986 has been prepared by G.M. Hogg, P.Eng. , at the
request of the directors of the Company. It summarizes the operations and
results of the evaluation program carried out over the entire period, most
of which were financed and directed by McFinley Red Lake Mines Limited
(McFinley).
The program has consisted of underground drifting and crosscutting, under
ground drilling, samping and geological mapping. All work has been carried
out on the two available levels in the McFinley shaft area (ISO 1 and 400'
levels). The program has been supervised by Mr. J.F. Whitton, Project
Manager, with J.S. Redpath Ltd. acting as mining contractor, and N.
Morissette Diamond Drilling Limited as drilling contractor. Assaying has
been carried out by a number of independent laboratories, and Lakefield
Research has completed some preliminary metallurgical test work.
This program of evaluation was undertaken by McFinley subsequent to the
termination of the Phoenix Gold Mines exploratory program in early 1985.
Its objective was the opening and effective sampling of gold zones in
proximity to existing workings, essentially as proposed in our report of
April 2, 1985. At this time work completed has been substantially in
excess of the proposed program, and the assessment of the resulting data
is still in progress.
PROPERTY DESCRIPTION, ACCESS
The McFinley property consists of 30 patented and surveyed mining claims
lying in the southwestern part of.Bateman Township, Ontario (see Figure
1). It lies about 5 miles north of the Cochenour Willans (Wilanour) mine,

and is accessible via gravel road from the town of Cochenour.
The property area is shown in Figure 2, and includes most of the McFinley
Peninsula as well as McFinley Island to the north. The Abino property of
Goldquest Exploration Inc. lies immediately to the south. The McFinley
shaft location is also shown on Figure 2 , and it is in this location that
underground exploration has been carried out over the past year.
Installed at the shaft site are a steel headframe, compressors, hoist
and generator, all owned by McFinley. Electric power for mining purposes
is presently supplied by diesel, but an electric power line does exist to
the Abino decline site to the south and could readily be extended to the
McFinley shaft site if necessary. Also installed close to the shaft are
two office trailers, and bunkhouse and cookery facilities sufficient for
approximately 30 men. These are maintained on a rental basis.
The vertical shaft, originally sunk by Little Long Lac interests during
the 1955-56 period, extends to a depth of 428 feet. Levels at depths of
150 and 400 feet were established at the time of sinking, and provide
current access. Track equipment, partially owned by McFinley, is used for
mining purposes. Loading pockets have not been installed so mine rock is
currently hoisted in cars.
HISTORY OF PROJECT
Early work in the McFinley Peninsula area located gold, silver and base
metal mineralization associated with cherty metasediments in what is now
the shaft location, and on McFinley Island to the north. Sporadic drilling
and trenching operations were carried on through the 1930's and 1940's,
but it was not until 1955 that underground exploration was undertaken.
At that time Little Long Lac interests opened the the McFinley shaft to

a depth of 428 feet, and established levels at depths of 150 and 400 feet.
The extent of the Little Long Lac work is shown in Figure 3 (in pocket),
totalling 1,358 feet of advance on the two levels prior to closure in
1956.
McFinley interests proceeded with surface exploration in the late 1970's
and early 1980's, defining extensive linear distribution of substantial
gold values within the property area by surface drilling. In August, 1984,
under agreement with McFinley, Phoenix Gold Mines Ltd. proceeded with the
construction of an access road, surface drilling, and the re-opening of
the shaft. To the termination of the Phoenix program in April, 1985, an
additional 1,570 feet of underground drifting was completed on the 150'
and 400' levels (see Figure 3, in pocket), and approximately 6,000 feet
of diamond drilling done from these openings. Approximately 34,000 feet
of surface drilling were also completed on the property during the Phoenix
program.
With completion of this program Phoenix interests were deemed to have
earned a 50 percent interest in the McFinley property. Management of the
project then reverted to McFinley, and underground exploration was
recommenced by this company during. May, 1985.
The subsequent McFinley program, largely completed during 1985, involved
the opening of an additional 2,468 feet of drift and 1,259 feet of cross
cut on the 150" and 400' levels (see Figure 3, in pocket). In addition,
30 feet of raising and 23,300 feet of underground diamond drilling were
completed, and an extensive chip sampling program was carried out. Since
the end of February, 1986, geological mapping, additional sampling and
data assimilation have been carried on. Recently much of the available
assay and geological data have been computerized.

GENERAL GEOLOGY
As illustrated in Figure l, the McFinley property lies along a NNE-trending
belt of intermixed metasediments, basaltic volcanics and ultramafic units.
This belt is traceable in sinuous configuration through the Cochenour
Willans (Wilanour) deposit area to the south, and thence in an easterly
direction into the Campbell-Dickenson deposit areas. It thus forms a very
important depositional locus for gold mineralization in the northern Red
Lake area.
In the McFinley property area this gold-bearing heterogeneous belt is
composed mainly of interlayered cherty metasediments, mafic tuff and
basaltic flows, all underlain by ultramafic talc schist. These rocks dip
to the northwest at 55 0 -75 0 , and normally strike in a N 30 0 E direction.
As indicated in Figure 4 (in pocket), which shows the geology of the
McFinley shaft area, the contact between the metasediment/volcanic complex
and the underlying talc schist is highly irregular to the north of the
shaft. This major irregularity, which may be the result of folding, fault
ing or depositional conditions, extends to depth at a plunge of approxim
ately 60 0 to the southwest. In detail numerous local irregularities caused
by faulting and/or folding are also noted, these being most prominent in
proximity to the talc schist contact.
Gold occurrence in the McFinley shaft area is largely restricted to the
cherty metasediments, which as a rock type is commonly geochemically
anomalous in gold content. Therein rather coarse native gold may occur,
which is often concentrated in minor contact-associated veining. Gold
also occurs in sulphide-rich bands or veins closely associated with pyrite,
arsenopyrite, sphalerite, galena and silver. These will be described in
greater detail in subsequent sections of this report.

EXPLORATION OPERATIONS
With financing arrangements completed the McPinley evaluation program
commenced during May, 1985. As noted, the stated objectives of this program
were (1) to open known gold zones in proximity to existing workings on the
150' and 400' levels, and (2) to effectively sample these zones by chip
sampling and underground drilling. These obvious requirements could not
be met during the previous program because of financial and time restrict
ions.
During the McFinley program 3,775 feet of new underground workings were
opened on the 150' and 400' levels, and 145 drill holes were completed
totalling 23,333.1 feet. The extent and location of the new drifting and
crosscutting completed are shown in Figure 3 (in pocket), and may be tab
ulated as follows:
Level Location Drifting (ft.) Crosscutting (ft.) Raise (ft.)

Total Footage* 2,468 1,259 30
* Of this total 1,295 feet of drifting and crosscutting were completed by Dec. 31, 1985.
It will be noted that the 157 Drift and the 403 Drift in the above tabulat
ion are "slusher drifts", designed to test the feasibility of controlled
mining along narrow, well-mineralized zones. It appears that a minimum
mining width of 3.0 to 3.5 feet can be maintained using this method.
G. M HOGG i ASSOCIATES LTD

A chip sampling procedure for all mineralized zones encountered was
recommended by Mr. H.H. Bird, P.Eng., and utilized throughout most of the
program. This involved the sampling with air gun of each mineralized face
on horizontal lines at waist and chest levels, and back sampling at five
foot intervals across strike. Approximately 6,000 samples were taken on
this basis in the course of the program, and analyzed for gold content.
Preliminary metallurgical test work was carried out on some composite
samples taken from various locations (see Appendix I).
In addition to current geological mapping by staff, W.A. Barclay, Consult
ing Geologist, carried out a structural study of gold distribution in
various parts of the underground area. Particular attention was paid to
establishing zonal continuity between the 150' and 400" levels. A limited
petrographic study on rock and ore specimens was also completed (see
Appendix II).
Necessary improvements to the mine plant, power plant and access road were
also effected during the program period.
Due to the considerable pressure of routine data acquisition and daily
direction of the program, it was not possible to provide other than basic
plotting of information during the operating period. Computerization of
data has since been completed, and thorough study and interpretation of
the results of the program are now in progress.
GEOLOGICAL CHARACTER OF SHAFT AREA
In reference to Figure 4 (in pocket), geological knowledge of the deposit
area has been substantially expanded and refined. Additional workings have
been opened in an intensely brecciated and silicified area close to the
talc schist contact (158 DR), and along a relatively regular chert horizon
(156 DR) to the north of the shaft. To the south the 155 and 401 drifts
GM HOGG i ASSOCIATES LTD
7.
have been extended along the sheared but comparatively regular sulphide
zone known as the "D" vein. Also, subdrifts have been opened in the foot
wall chert area (157 DR) on the 150' level, and along a narrow chert hor
izon in the hanging wall chert/boitite tuff milieu (403 DR) on the 400'
level.
Comments are given in the following text in respect to (1) the "C" Zone
(158 DR) , (2) the "B" Zone (156 DR) , (3) the "D" Zone (155 DR and 401 DR) ,
(4) the Footwall Chert Zone (157 DR), and (5) the 403 Zone (403 DR). These
various mineralized zones are perhaps more clearly identifiable in Figure
5 (in pocket), which shows the extent and configuration of the zones as
presently understood.
C Zone Area;
As noted, the C Zone area (158DR) is intensely sheared and brecciated. Formational dips are to the west at about 45", but irregular. Brecciat ion of chert and veining is widespread, as is silicification in the containing biotite tuff. Disseminations and fracture fillings of pyrite are common, and generally fine gold occurs in a discrete lenticular zone of silicification along the northern end of the 158 drift. The auriferous zone appears to conform to an embayment in the talc schist/ biotite tuff contact, but the limits and configuration have not yet been defined.
Drilling has indicated a similar zone may exist near the shaft on the 400' level, but it is unlikely that this is continuous with the zone existing in the 158 drift on the 150' level. It is possible that other en echelon zones similar in character occur between the two levels.
B Zone Area:
The B Zone area includes both auriferous sulphide veining, and narrow cherty horizons which contain some visible gold. These zones exhibit a northerly strike and dip at approximately 60 0 to the west. Although excellent specimens of free gold have been obtained from the cherts in this area, adequate mining widths and zonal continuity have not been demonstrated. This zone has been opened along the 156DR.
D Zone Area:
The D Zone south of the shaft has been followed for a distance of approx imately 1,000 feet on the 150' and 400' levels, and has been intersected

in drilling at a depth of 800 feet below surface. It is a variably sheared sulphide/vein system containing generally coarse pyrite, arsenopyrite, pyrrhotite, sphalerite and galena in varying amounts. The zone pinches and swells along strike, from a few inches in width at the minimum to about 5 feet in width at the maximum in the areas observed. Occasionally very high gold and silver values have been reported from the sulphide zone, but the material appears to average in the range of 0.20 oz.Au/ton and 4.0 oz.Ag/ton. It is notable that high silver values occur only in the sulphide-rich mineralization of the D and B Zone complexes.
The D Zone dips at about 65 0W, and appears unconformable with the foot wall cherts to the east. It may well be conformable with the overlying formations to the west, however.
Footwall Chert Zone:
The Footwall Chert Zone lies subparallel to the D Zone, and dips at approximately 60 0W, It consists of veined chert up to 4 feet in width, which contains some disseminated pyrite and erratically distributed coarse free gold. Gold mineralization favours the contact areas, and in the 157 drift has been observed over a strike length of approximately 150 feet. This portion of the zone has not been opened on the 400' level but has been located in drilling.
403 Zone:
The 403 Zone was located in crosscutting to the west of the D Zone on the 400' level. It is a narrow chert horizon in which coarse visible gold occurs, again favouring contact areas. The zone extends over a strike length in excess of 500 feet on the 400' level, and has been located by drilling at the 150' level, and below the 400' level.
On the 400' level the 403 Zone is overlain by a 25 foot zone of veined and brecciated chert in which some visible gold has been observed. This unit has not been located at the 150' level, nor has it been extensively drilled elsewhere.
In review the recently-completed program has indicated the C Zone area to
contain a series of rather flat-lying auriferous silicified zones in a
strongly disturbed environment. The configuration of these zones is complex
and additional work will be required for definition.
The mineralized zones to the south of the shaft are lenticular, dip at
60 0 -65 0w, and plunge to the south at approximately 60 8 . Two zonal types
are recognized, both apparently stratabound and exhibiting good continuity.
C.M HOGG& ASSOCIATES LTD.
9.
Evidence suggests that the sulphide type has very great tonnage potential
at a limited grade, and that profitable mining of the "swell" areas will
be possible. The gold-chert zones so far recognized are probably of very
good grade, but of lesser tonnage potential.
In the immediate vicinity of the shaft at the 150' level several gold
occurrences have been noted. These include the original B sulphide zone
investigated by Lac interests in 1955-56, and visible gold in overlying
cherts. Zonal continuity in this small area appears' poor, however, and the
existence of substantial reserves therein is unlikely. It will be noted
that the shaft centerline will intersect the projected southerly plunging
talc schist contact at a vertical depth of about 650 feet.
SAMPLING Si ASSAYING
Sampling of the McFinley underground workings on a systematic basis has
been extensive. However, the often coarse and erratically distributed
native gold in the deposit generally, a condition which could not be
anticipated at the outset of the program, has severely limited the effect
iveness of the resulting sample data.
Numerous cases exist in the 157 and 403 slusher drifts in particular,
where visible gold has been noted in face mapping and in muck, but all
face and back samples taken on the structured basis have returned values
of less than 0.10 oz.Au/ton. Recently some panel sampling, that is, random
sampling of each formation exposed at a face, has been done for comparative
purposes. An average of panel samples in one case in the 403 drift yielded
a value in excess of 0.50 oz.Au/ton, while the average of chip samples was
less than 0.10 oz.Au/ton, While the panel sample would appear the more
representative in this instance, the procedure is obviously subject to
undesireable bias on the part of the sampler.
GM HOGG 4 ASSOCIATES LID
10.
A second related problem was encountered in assaying procedures, identified
by a system .of duplicate assaying which was applied to all earlier samples
taken during the program. In some cases samples known to contain visible
gold returned very low values, and in others a very wide discrepancy in
check values was evident. In the 403 Zone, for example, a spread of 16.30
to 0.13 oz.Au/ton was reported on one sample. This problem was subsequently
overcome to some degree by finer grinding of samples, and by more thorough
mixing of samples prior to splitting.
At this time then, because of uncertainties in the accuracy of sampling
data, it is not possible to accurately determine the grade of potential
ore zones. This is particularly true in areas of coarse gold occurrence
such as the Footwall Chert and 403 Zones, which the writer would provision
ally estimate at a grade of 0.30 to 0.50 oz.Au/ton over narrow mining
widths.
In respect to the sampling program the reported results accompany this
report in Folders l and 2. Folder l contains sheets showing contoured
assay ranges over sampled openings at a scale of l inch to 20 feet (horiz
ontal drill holes included on Waist Level Sample Sheets). In Folder 2 the
actual assay values and locations are shown on the l inch to 5 feet work
sheets from mine records.
POTENTIAL RESERVES
Limited openings exist on the 150' and 400' levels of the McFinley shaft
area, and several potential ore zones are exposed within them. As noted,
present sampling data is considered unreliable, so potential reserves can
be estimated only on a provisional basis, and are restricted to areas
which are presently opened to some degree.
Q.M. HOOO 6 ASSOCIATES LTD.
11.
Figure 5 (in pocket) illustrates the character and extent of the various
mineralized zones of the McFinley shaft area as presently known, In ref
erence to this zonal configuration, the provisionally estimated reserves
immediately available in the shaft area above the 400' level are as
follows:
D Zone; 100,000 tons @ 0.20 oz.Au/ton, 4.0 oz.Ag/ton
Footwall Chert Zone; 20,250 tons @ 0.40 oz.Au/ton
403 Zone; 30,000 tons @ 0.40 oz.Au/ton
C Zone; 3,000 tons @ 0.30 oz.Au/ton {above 150' level)
Note: These are "in place" reserves, uncut and undiluted.
It should be emphasized that the possibilities for the development of
substantial additional reserves above the 400' level are by no means
exhausted. It will also be noted that auriferous chert and sulphide zones
have been intersected in exploratory drilling at depths in excess of
800 feet from surface, so the entire mineralized system in the shaft
area is open to the south and to depth.
FUTURE EVALUATION REQUIREMENTS
At this time the resolution of grade levels in the various mineralized
zones exposed in the recent McFinley program remains of the highest prior
ity. As noted, the 157 DR and 403 DR are "slusher drifts" on strongly
mineralized chert zones which are well-suited to the extraction of size
able bulk samples. There are also numerous sample sites on the sulphide-
rich and metallurgically complex D vein, but since most openings lie along
main access drifts care must be taken in sample extraction.
Since there are few laboratories which are capable of testing the sizeable
quantities of material required for an adequate determination of grade,
the options available to McFinley are (1) to arrange a large scale test at
CM HOGG l ASSOCIATES HO
12.
an existing milling plant, or (2) to construct a small crushing and
extraction plant on site.
Insofar as grade testing at an existing mill will involve relatively large
tonnages, and there may still be doubt as to actual grade levels maintain
ed, the construction of a less costly test mill facility on the McFinley
property is considered the more desireable alternative. Testing will, of
course, be limited to the treatment of auriferous chert material which is
amenable to high gold recovery using gravity methods. The sulphide mater
ial, on which grade levels are better defined by past work, should be
concurrently subject to metallurgical testing by a laboratory such as
Lakefield Research to establish the necessary parameters for larger scale
mill design. However, only very limited tonnages of the D vein material
will be required for this investigation.
It is also clear that the shaft area as presently opened represents only
a very small part of the potential ore system in this location, and it
is not necessarily the best. Accordingly it is recommended at this time
that a deep drilling test be undertaken as illustrated in Figure 6.
In this respect geological projection suggests that the large, strongly
mineralized D zone complex, including both auriferous chert and sulphide
vein material, will intersect the highly disturbed talc schist contact
area at a depth of 1,500-2,000 feet approximately 1,000 feet southwest of
the shaft. This may well produce an area of strongly deformed and heavily
veined gold concentration of the C zone type. A 10,000 foot surface drill
ing program is proposed to test this possibility.

contingent on a number of variables which remain uncertain at this time.
Comparative cost ranges are given for the two alternative test programs
noted in the preceding section.
Alternative 1; {Mill Test)
This program is estimated to involve the extraction and milling of 20,000-
25,000 tons of material which would be milled at a local facility over an
eight month period. Costs include mill rehabilitation, start up and closing
costs for the mill, to be operated at a rate of 250 tons per day.
At the McFinley property no extensive modification in muck handling pro
cedures are contemplated, but a ventilation raise would be required, and
stope preparation work is necessary. Local trucking costs are considered.
Including the proposed surface drilling program, metallurgical test work
and support services the operational cost is estimated at $ 4.5 million.
This would be reduced by the forcast production and sale of approximately
6,000 ounces of gold ^ 2.5 million).
Alternative 2; (On Site Test)
This program would involve the extraction of 5,000-6,000 tons of auriferous
chert material which would be crushed and tabled at a 50 ton per day plant
erected at the McFinley property. An eight month operating period would
be required. In this instance no modifications of consequence would be
considered in the existing underground workings or mining plant.
Including the proposed surface drilling program, metallurgical test work,
milling plant construction and support services the total cost of this
program is estmated at $ 1.4 million. This would be reduced by the forcast
production and sale of approximately 2,500 ounces of gold ^ 1.0 million).

CONCLUSIONS S RECOMMENDATIONS
The recent evaluation program conducted by McFinley on its Bateman Township
property in the Red Lake District of Ontario met the stated objectives with
positive results, with the exception of the completion of a fully effective
sampling operation. The extremely erratic distribution of gold mineralization
within the auriferous cherts in particular could not be anticipated, bearing
in mind that only a few occurrences of visible gold had been observed in
the underground workings available prior to the inception of this program.
The extensive chip sampling operation, while believed ineffective in the
establishment of firm grade levels, was successful in defining potential
ore areas. These are recognizeable on the basis of frequency of assay values
in excess of 0.06 oz.Au/ton, often coupled with visible gold occurrence.
It is our opinion that the McFinley property has the potential of becoming
a profitable gold producer. However, prior to serious considerations in
respect to production and development to deeper levels, it is necessary to
resolve uncertainties in grade definition and prove the presence of potent
ial ore concentrations at depth.
With these objectives in view a program of bulk sampling and surface diamond
drilling has been proposed, with alternative sampling plans defined. The
installation of a small sampling plant at the property, with the capability
of free gold recovery, is considered the more effective and least costly
of the two alternative plans and its implementation is recommended. On this
basis the proposed drilling and sampling program will cost approximately
S 1,400,000.

The gold extraction varied with the type of ore aample. The free gold
ranged from 6.3 X to 18.9 X. 46.5 X - 79.4 X of the gold waa extracted by cyanide.
The overall gold recovery waa 52.8 X - 93.2 Tt. The poor gold recoverlea may have
been due to micron alee gold partlclea Included In sulphide minerals.

These features are suggestive of extensive recrystallization.Carb veins out across all bands, sometimes with assoc preferential growth of carb along planes of Intersection with amph-rlch bands. Carb later than sulphides. Some amph Is found along the margins of the carb velnlets within qz bands, although there Is no other nearby amph In those bands. Recrystallization and carb velnlng at or soon after the peak of regional metamorphism?The sulphides are essentially absent from the carb) they are highly localised and were probably Introduced to the rock before the carb velnlng. The qz gs, as mentioned above, Is quite constant throughout, and Is a secondary feature. It Is hard to tell on HS/CTS scale whether the banding Is a primary feature.Summary i a well-banded quartz amphibolite, cut by late carbonate velnlng. Minor concordant pyrrhotite. A "banded chert 1 In mine terms, It Is quite possible {but not definite) that this feldspar-free banded rook Is e metasediment, subjected to greenschlst-faoles metamorphism [1], although the simple mineralogy Is Insufficient to further constrain the conditions of metamorphism. Intense multi-stage rock deformation In the Red Lake district (e.g. [2]) clearly requires care In Interpretation.

Found particularly In the qz-rich bands In the rock, sometimes assoo with carb. 3H.* Apatite- colourless equant grains of high relief and very low bir. Max gs I80x150um, located In qz-rich bands. Tr.
Texture) Leucocratic bands are composed largely of recrystalllzed qz (see also Descr. 222). Carb also shows possible traces of recrystallization (above). Carb may enclose anh opaque grains, In addition to delicate sprays of feathery amph. Opaque grains are located at or near leucocratic - melanocratic margins, a feature also noted in Descr. 222. The ore phase(s) may be late In the paragenesis) It is anh, with qz and carb Inclusions, displaying Irregular margins, often enclosed by carb.
Summary) amphibolite ('banded chert 1 In mine terminology),'metamorphosed at upper greenschist to lower amphibolite grade. Iron formation and chert are recorded as interflow sediments In the local volcanic stratigraphy [1], A (volcano-) sedimentary origin Is consistent with the petrographic features of both thin sections (Descr. 222-223), and may be applied provided good field data can exclude the possibility that the light and dark llthologles were mingled by strong folding and/or deformation.
The fact that the sulphide Is associated with quartz-rich material In this sample, and with darker lithologles In Descr. 222, Is compatible with the notion that In this rock quartz-sulphide veinlng was Injected parallel to compositional contacts.

Harid specimen data) banded amphibolite, carrying approx 101 pyrr concentrated Into particular bands. Some carb in bulk (indicated by eff in dil HC1). Late (7) silica veins with dark selvages localise sufficient gold to constitute exceptional ore. Apparent remobllizatlon of some gold along thin {*X1mm) cracks. The auriferous fractures are normal to the rook banding, and examples up to 13mm long are visible. Some pinkish (?) garnet is visible in the PH. 1 piece and 3 chips.
Major Minerals)* Gangue- 80K.* Pyrrhotite- anisotropic, anh. 19J.
Minor and Accessory Minerals (2)))" Native gold- isotropic, with reflections from scratches on rotation. Rounded blebs up to 500x200um are found in the pyrr. A few blebs (max size 20x20um) and velnlets of gold (and lesser amounts of blebby pyrr) are enclosed by sphal. The gold In this setting has a harsher colour than the larger masses elsewhere, perhaps because it is recessed Into the sphal during the grinding process, and acquires a rougher finish as a result. Apparently extensively remobllizedt see Texture section. Velnlets occur with lengths OOmm, roughly 50um wide, boundaries undulating on a tOum scale, often enclosing small rounded pieces of the silicate vein margins. IJ(-).* Sphalerite- dark grey relative to pyrr, and darker than mag. Isotropic, with Internal reflections. 2 large grains (800x600 and 1200x500um) visible in PH in gold-rich area. Tr.* Chalcopyrite- max ga 60x40um, In pyrr. Tr.
Texture[ gold and pyrr may have been mobile, In some degree, at the same time) gold and pyrr both plate sphal, as rims of variable width (5-60um thickness of gold). There Is local enclosure of gold by pyrr. A 'sunburst' effect of pyrr and gold Infilling spaces between radiating silicate laths (amph?) Is seen In the main gold mass on one side of the mount. Some of the gold velnlets can be traced back to silicate-hosted gold blebs. In only one case was another ore mineral (sphal) found In small amounts In a gold velnlet.Remoblllzed gold appears to cut right through the garnet-bearing bulk, suggesting mobility after the peak of metamorphism. The gold velnlets are located in fractures in brittle silicates, not within the massive sulphide bands. To be precise, the favoured location for the fracture fillings is In dark silicate bands, not In white (T) qz-carb or In sulphidic bands. The fractures are straight) they appear to be locally offset (perhaps due to partial filling of an array of en echelon fractures), but are not folded. Preferential brittle fracturing has created this small-scale llthologloal control.
Summary) metabasite, probably of original basaltic composition [13, which has attained almandine amphibolite facies grade. Ooid may have been Introduced during a veinlng event) It was then partially remoblllzed Into late extensional fractures In a brittle silicate host.
Preparation of PTS would elucidate details of silicate-gold relationships and facilitate EPM, If required.
Age) Archean.

Hand specimen data) grey-black vfgr siliceous ('cherty'1 ) rock, banded, with extensive pyrr content, approx 25J In the whole rock. Minor py and abundant traces of native gold are also visible, particularly on sawn surfaces. The gold is assoo with gangue In pyrr layers, and shows evidence of filling of late fractures, a process seen so well In the companion sample (Desor. 224). Very siliceous sample) no eff In dll HC1. 1 pleoe and 1 chips.

Minor and Accessory Minerals* Pyrite- euh sections in pyrr. Apparently pure, except for rare, rounded pyrr inclusions (max 100x20um). Max gs 900x600uro. In one unusual case a horseshoe-shaped py mass nearly surrounds a small pyrr grain. 2\.* Native gold- soft yl tint, occurs as rounded blebs In pyrr, max size l80x7Qum, Isotropic, but with variable reflections prominent In ext positions, located at scratches in the soft metal surface. Mostly found as fracture fillings In brittle gangue) the largest velnlet Is roughly 2mm long and 60um wide. Abundant tr.* Chalcopyrite- max gs t60x)00um, located 'in pyrr In a sulphide-filled fracture. Tr.
Texture; open to Isoclinal drag folds [2] are traced out in silicate gangue bands within the pyrr bulk. Ooid cuts qz-rich veining within the sulphide-rich rock.In plane of PTS(C), gold-filled sections of fractures may begin at pyrr contacts, but often do not. Some sulphides do occur In the fracture environment) fractures contain either gold or sulphides) some pyrr fractures occur, one parallel to a gold fracture but some way along the same band, with Inclusions of py and chalc.One rectangular il30x200um bleb of gold is in contact with pyrr at either endi It bridges a thin silicate band within the sulphide mass, and is parallel to the thin gold-filled fractures in the brittle gangue beyond. Another thin, ragged, gold-filled fracture has the same orientation, 1.2mm along the same band. An exception to the general rule, two thin veinlets of gold extend along the.silicate band, parallel to the sulphide. This apparent anomaly may be due to 'sheltering' of the thin gangue (within the massive sulphide) from the extensional cracking in the wider bands. Cold is never found deep within the sulphide) it Is always near the silicates.A tentative history of this rock would Involve relatively early sulphide introduction, folding, veining and gold Introduction, and late fracturing and gold remoblllzatlon. Cold is thought to postdate the sulphide.
Summary) gold ore, apparently hosted in Iron formation sediment, as opposed to metabasio rooks (o.f, Descr. 224, [1]). Structural relations suggest late remobilizatlon of gold, following the peak of the deformatlonal event recorded In the folding of the (presumed) banded sediment.
Arsenopyrite and galena have been reported from the area [1], - but were not noted here.
Age) Archean.
