SUMMARY

Canamax, as the operator of the 50/50 Bell Creek Joint Venture with Dupont of Canada initially, and now with

"Canadian South African Management", who most recently

replaced DuPont as the J.V. partner, have in 1984 continued to explore the Bell Creek properties located northeast of Timmins.

The gold oriented exploration program in the project area consisted.of .diamond drilling only. This work was executed during the winter months, was exploratory in

nature and involved various optioned properties in Hoyle and Murphy Twps. There, dri11-targets already existed from

earlier geophysical surveys, or drilling was again continuing on known auriferous vein zones as in the case of Marlhill. A total of 2,451.0 nfetres of drilling was performed in 13' drill holes.

No drilling was done in 1984 on the North - or Bell Creek auriferous zones which have recently been made acce ssible from highway 101 by the construction of a gravelled motor road. Also currently underway are constructions of ancillary facilities at the Bell Creek mine site for a shaft- sinking and underground development program aimed at the future exploitation of the above named gold deposits.

CONCLUSIONS

A 250 metre long segment of Marlhill's MI vein lying between holes 212 and section 150W is fairly straight and probably mineable. The latest drilling shows that the vein can also be continuous to a depth of 200 metres but more drilling is needed to verify dimensions and average grade, the latter is probably in excess of 4 gms Au. A potential - but early tonnage reserve of at least 200,000 tonnes can be calculated using the following dimensions:

250m x 150m x 2.0 x 2.7 sp.g.

The presence of a second vein zone nearby, the BRI vein, has been known to exist for a long time but was difficult to follow in old drill holes. Additional future drilling on this vein should follow-up on the success of our most recent drill holes in tracing this zone.

Drilling on the Rose and Wetmore Options culminated with the abandonment of these properties. Although these claims may still hold some merit for more exploration, none could be recommended at this time.

The completion of our drilling on the 04 group brought these claims to 'Lease' as well as the information that the northern limits of the volcanics lie on Stringer ground and no further north.

The results of the Allerston drill hole show that weak alteration zones containing some gold do exist west of the dike and in line of strike of those east of the dike.

RECOMMENDATIONS

Surface exploration is recommended for the Broulan-

Marlhill properties, the bulk of it is in the form of diamond dri11 i ng.

DRILLING

Broulan S^ Lot

Drill one hole of about 150 metres in length north

of the North Zone and north of 81-45 with the objective to explore the ground between this hole and the graphitic marker. Known to date are several parallel auriferous zones

in the hangingwalls of the North Zone and this planned hole,

which is on the same block of ground as all zones would seem to stand a good chance of finding others in the footwalls.

Marlhill - Broulan NH Lots

Several holes are recommended from 150 - 200m each

to test the MI vein at depth in the large unexplored gap laying between the hole 211 intercept and section Line SOW.

This drilling will simultaneously search for the NW extension

of the BRI vein.

Another hole should be drilled due west from a location 30 metres north of the base line on BR ground. After cutting the MI vein zone, this hole will explore for

a possible third vein lying west of the MI vein and which may strike northerly as well. The existence of such a zone

is suspected from a so far unexplained vein intercept in hole 80-18 assaying 8.0 gms Au over 6.7 metres and which cannot be 'correlated with the MI vein. {DDH 80-18 following

the strike of a vein?)

IP SURVEY

Marlhill S?s Lot

Perform a carefully conducted IP survey with a twotarget approach:

1) Search for subtle IP anomalies coupled with resistivity-highs extending south-easterly from the MI-BRI veins.

2) Run a survey using different dipole separations on lines which cross the possible strike extensions of our. two North Zone horizons to the east of Bell Creek.

The re-cutting and chaining of older Rosario picket lines at 125m intervals for a total of 5 km of survey lines would have to precede the IP survey if we consider surveying the entire ^ lot.

STRIPPING

A re-evaluation of areas suitable for bulldozing or backhoeing in the 4 corner areas of the Marlhill-Broulan \ l ots may selectively reveal additional areas for stripping. If such work were contemplated, it would necessitate the prior clearing and burning of trees, a job preferring the fall or late winter months.

INTRODUCTION

The 1984 drilling was the latest exploration work in a now 5 year old search for gold deposits throughout the project's property holdings. This work was initiated by Rosario, which became Canamax, in equal partnership with DuPont till 1984, when Canadian South African Management acquired Dupont's share.

The past exploration efforts led to the discovery of three separate gold deposits for which one of these, namely the North Zone's 'A' Horizon, production is planned once it's economic potential .can be verified underground together with a then prevail ing strong price for gold. The occurrence of a second nearby deposit in the form of the. dual Bell Creek Zone, can later be further evaluated by concurrent underground exploration as well. No diamond drilling was performed this year on the above named two deposi ts .

This report deals with some additional drilling oh a third deposit known as the Marlhill vein (s) and on other exploratory drilling on optioned and staked ground as des cribed below in detail.

- 6 -

PROPERTY

The Bell Creek project comprises .109 parcels (40 acre claim equivalents) in the form of patented lots, staked and optioned claims in Hoyle and Murphy Townships.

The aggregate property area now actively being held totals 4360 acres or 1765 hectares.

The main block of ground is contiguous and extends from Lot 8 in Hoyle Twp. westerly to Lot 4 in Murphy Twp. In north-south direction the property extends from Con II north to include the south ^ o f Con IV in Hoyle Twp., while in Murphy Twp. it extends north from the Tisdale-Murphy boundary to the south h o f Con IV, as well. In addition there is one isolated group of 4 claims in Lot 5 of Con II in Murphy Twp.

The Bell 04 group of staked claims in Hoyle and Murphy Twps. have now earned sufficient assessment credits, therefore, an application for.'Lease' was filed.

During the year 8 staked claims in Murphy Twp., - known as the -10 group, were allowed to lapse as they were assessed unfavorable from geophysical data and from the fact that they lie west of the Burrows-Benedict Fault which implies displacement of our Bell Creek stratigraphy. Two other patented and optioned properties were also dropped as a consequence of the herein described drill program, namely the Rose h L ot in Murphy Twp. and the 10 patented Wetmore claims are not included in the above total".. A list of all active claims and options is appended.

ACCESS

Canamax has recently constructed a gravelled motor road to the Bell Creek Shaft site on the Broulan Option. The rest of the Bell Creek properties are best accessible from here by muskeg bombadiers over the various trails or winter roads.

The distance from Timmins to the property travelling east on highway 101 and later on the gravelled road via the former Reef Mine, is about 25 km.

PREVIOUS WORK

The heavily overburdened area was prospected for gold many years ago when an auriferous quartz vein was found in Lot 9 of Con II in Hoyle Twp. This occurrence was later staked and drilled by Broulan Reef Mines which in the pro cess patented their claims. In the late 1970's Rosario Resources acquired this property along with various other patented h l ots or staked claims. These properties still represent the core of the actual Bell Creek holdings.

Following the acquisition of this ground and the layout of grids, Rosario then embarked on a program of overburden drilling and ground geophysics initially alone and later in joint venture with DuPont of Canada. The then ongoing exploration work as mapping, trenching and diamond drilling was continued with Amax (Canamax) coming to the scene in 1982 replacing Rosario as the J.V. partner and operator o'f the program.

- 8 -

During the course of the past activities, the Marlhill MI vein system was found followed by the Bell Creek dual auriferous zones and the North Zone's orebody, known as the 'A' Horizony all located in Hoyle Twp.

Also prior to 1984, other exploratory diamond drilling was performed on the Allerston, Stringer, Dommel , Fisher, Prentice, *Thomson, *0ntario Paper, *Joanis, Chartrand, Rose and Wetmore options, the last six properties are now no longer part of our active holdings. Since the inception of Rosario's diamond drilling phase in 1978, a total of 31,664 metres of drilling was done over the entire- project area and was shared by all joint venture partners. * = p roperties never included in project 045, but incl. in total drilled metreage.

RESULTS OF THE 1984 PROGRAM

A. F i e 1 d Work - Diamond Drilling

Some of this year's drilling was done on veins in Marlhill's northern ^ lot where a multiple vein system may develop into a third gold deposit.

Other drilling also reported here in detail was exploratory in nature and was intended to further evaluate some of our optioned properties like the Rose and Wetmore options where some of our drilling was already done in 1983. As the overall results were disappointing, these two properties were recently dropped.

With the simultaneous objective of fulfilling assessment work on our 04 group of staked claims, located along the northern fringe of our property - holdings, a cross-section was drilled to explore a segment of this area. Drilling revealed the existence of extensive sedimentary formations in this totally overburdened area.

Finally, one drill hole was put down along the common Allerston-Broulan Reef boundary with the objective to check across the postulated strike extension of the Bell Creek stratigraphy west of the diabase dike. A weak aurife rous zone encountered here may need follow-up work at a future date.

- 10 -

l - Drilling on Marl hi 11-Broulan Option

Two drill holes for a total of 471.0 metres were drilled in the winter of 1984 on Marlhill's northwest h lot. These 2 holes, numbered 201 and 202, were drilled below MI vein intercepts of 1983 drilling. Holes 201 and 202 established the downward continuity of this vein to a vertical depth of 150 metres and 200 metres, respectively. The return of erratic gold assays from this vein indicate the sporadic nature of free gold occurring mostly in quartz rather than with more consistent sulphide associations.

f

Three more holes, aggregating 447m i numbered 203, 211 and 212, were drilled during the winter from the adjoining Broulan Reef northern^ lot in westerly direction so as to intercept the east dipping MI vein at greater depth. As can be seen on the drill plan, the curving MI vein strikes northerly at this point. The MI vein was cut, however, all vein intercepts are already on Broulan Reef ground. The vein intercept in hole 203 assaying 6.47 gms Au over 2.4 metres appears to correspond to the Broulan Reef #1 vein (BRI), which outcrops south of the 212 collar. Thus, hole 203 was probably stopped short of reaching the MI vein as this vein retreats northwesterly from here on. At the same time and as to compound the difficulty in reaching this vein, DDH 203 deflected significantly to the north. If the MI vein indeed lies ahead of the end of this hole, it's location would be vertically below the Marl hi 11-Broulan Reef boundary. As to the above mentioned BRI vein, if it continues in northwesterly direction then it is projected to enter Marlhill ground about 160m north of the surveyed Marl hi 11-Broulan four corner post.

- 11 -

What follows are some brief comments on drill holes 201 , 202, 203, 211 and 212.

DDH 045-01-201

This hole was drilled due south at -75 on Line 150W. The MI vein was cut at a vertical depth of 150 metres which is 100m below the intercept in hole 167. Sulphide mineralization and gold contents are low, similar to hole 167 above. The vein zone appears spread-out along this

drill section but it's true width will be less than indicated, This hole was not surveyed with a directional drill hole compass but is assumed to have deflected to the west similar as other surveyed holes have done in this area.

Drilling on this 150 W section appears to have delimited the vein's westerly extent for the time being.

DDH 045-01-202

This hole on section 90 W was drilled due south also, but at -70 0 . The MI vein was cut at a vertical depth of 200m, or 140m below the hole 169 intercept. The direction al Tropari survey indicates that the vein intercept was to the west of section which brings the assays obtained in line

with those from holes 166 and 168.

- 12 -

DDH 045-01-203

This hole was collared on Broulan ground and drilled due west at -75 0 . It's objective was to cut the two northwest striking and east dipping vein zones known as the BRI and MI veins, at greater depth. As already mentioned above, only one vein intercept was achieved assaying 6.47 gms over 2.4 metres and which seems to correlate with the BRI vein. Thus the MI vein was apparent ly not reached as the drill hole and MI vein zone turn away in opposing directions.

DDH 045-01-211

The hole's collar was 35 metres south of 203, drilling was also due west at -75 0 and has accomplished it's objective to cut the east dipping BRI and MI vein zones. Both zones are spread-out and so are their values. From earlier drilling here the MI vein is known to be 'broken-up 1 along this section, which suffered maximum deformation. The vertical depth of the vein intercepts was 50 metres for the BRI vein and 90 metres for the MI vein.

DDH 045-01-212

The direction of drilling was again parallel with hole 211 at the same dip. As above, the drill targets were the two veins of which the BRI vein crops out near the hole's collar and which was subsequently cut near surface, assaying 7.98 gms. Au over 2.2 metres. The MI vein was also relati vely well .mineralized and showing some VG. The geological width of the zone was 5.2 metres and this can be substan tiated with averaged assays of 2.86 gms over this width or 4.19 gms over 2.0 metres. This intercept was 75 metres vertically below surface.

2. Drilling on Rose Option - Murphy Twp.

Three drill holes numbered 207, 208 and 209 were drilled during the winter for a total of 579.0 metres-.

The purpose for this drilling was to evaluate previously untested IP anomalies and a minor auriferous zone found in last year's drilling.

As a result of this work a broad geological cross- section was obtained across most of this heavily over burdened ^ lot. Rocks encountered were all of mafic volcanic origin. Their strike is roughly E-W and they dip steeply to the south. The talcose komatiitic basalt and fragmental units from hole 199 re-appeared again in this year's hole 207, showing the continuity of these units in E-W direction. Lacking other work along strike it is difficult to say whether they actually are the western extensions of the Pipestone Fault stratigraphy.

The weak auriferous zone in last year's hole 199 does not seem to have continuity, at least not in westerly direction and where tested with hole 207. A more interesting and broader alteration zone found in hole 208 correlates with an IP anomaly but unfortunately does not contain any mineralization of economic interest. It was, therefore, recommended not to excercise another year's option when it was due in July.

- 14 -

Below follows a brief summary of 1984 drill holes:

DDH 045-01-207

This hole was collared some 58 metres west of hole 199 and drilled north at -50 0 . Rock types encountered are talcose komatiitic basalts and fragmentals as in 199 but without it's small gold occurrence.

DDH 045-01-208

This hole was collared south of hole 199 and drilled north towards it, nearly accomplishingan 'overlap 1 with the south dipping volcanics. A shear zone near the top of hole and a pyrite-minerali zed, strongly calcitic alte ration zone from 135.0 - 143.5 metres will account for the IP anomalies. This zone contains locally abundant tour maline but no anomalous gold values.

DDH 045-01-209

Exploratory drilling to the north of 199 encounter ed mafic fragmental volcanic rocks but no alteration zones of any kind.

3. Drilling on Wetmo re Option - Hoyle Twp.

A total of 162.0 metres were drilled in one driM hole numbered 213. The purpose for this drilling was to evaluate certain - hitherto untested horizons prior to up coming option payments in August. In the light of the disappointing results obtained, this option was likewise not renewed.

Drilling concentrated on geophysical targets pre viously located. These consisted of magnetic and EM anomalies which are locally flanked by responses from an induced polarization survey. The area is heavily over burdened. The strike direction of the underlying rocks was determined from the EM survey. Drill hole 213 showed that a sequence of sedimentary rocks dip northerly. This reve lation implies the possible existence of a previously un recognized syncline, marked by the presence of these rocks in correlative direction with a regional AEM anomaly.

Summary of DDH 045-01-213

This hole was drilled due north at -50 on Line 500E, collar location was 225N.

It's target was a HEM anomaly with flanking,IP and some subtle magnetic correlations. The hole stayed in sediments all the way as alternating argillite with grey wacke beds whi eh, signi f icantly, dip steeply to the north.

The argillite contains some graphite and pyrite. Nothing was seen to explain the weak mag feature. Check samples sent for assay did not reach the gold anomalous threshold values of 0.5 PPM.

4. Drilling on Staked Claims 04-Group, Hoyle Twp.

With the performance of three drill holes numbering 204, 205 and 206 for a total of 606.0 metres of drilling', we completed all assessment work required to bring all claims in this group to 200 days, while exploring this previously undrilled area for mineralized zones.

The 3 holes were put down north of the Stringer Option and along the old Rosario Line 36E. The holes were planned to roughly cross-section the area in N-S fashion while checking a local weak HEM conductor at the same time. Thus, drilling covered portions of claims P525276, 525303 and 525306.

All holes encountered a folded sequence of massive greywackes with argillites striking E-W and showing local variations in their dips as being either north or south dipping. The width of these sediments as defined by the drilling amounts to 1700 metres when measuring from Rosario Hole 80-4 located in the north k o f the Stringer Option, which already was in sediments.

Nothing of any economic interest was seen in the drilling. All check samples sent for assays returned NIL values in gold, even from some quartz veins or from minor graphitic or pyritized sections.

5. Drilling on Allerston Optioned Claims - Hoyle Twp.

Drilling on these optioned claims which already have 'Leased Status 1 amounted to 186.0 metres in l drill hole.

The Allerston Hole was numbered 210 and was drilled north at -50 0 along it's common boundary with Broulan. The hole's objective was to explore across the projected strike extension of the Bell Creek stratigraphy in westerly direct ion from the diabase dike.

Hole 210 encountered a weak alteration zone assaying 1.95 gms Au over 1.2 metres in tuffaceous basalt near it's contact with leucoxene basalt. This occurrence is near other anomalous gold intercepts in hole 81-17 which are all roughly on strike with other auriferous alteration zones in similar rock east of the dike. Although weak in character, these occurrences nevertheless point out the direction for future exploration.

B. Off i c e Interpretation

North l B ell Creek Zones -

A "Surface S Drill Hole Geology Plan" was pre pared at a scale of 1:1000.(In Back Pocket).

The plan shows outcrop-geology near the 290 metre surface level and an up-dip projection of drill hole geology or mineralized zones to the 250 metre level, which is approx. 10 metres below the bedrock-overburden inter face.

Interpreting a coloured print of this map suggests an easterly plunge and a structural deformation of the volcanic/sediment assemblage along the course of Bell Creek.

North Zone -

A 'Drill Hole Deviation Plan 1 at a scale of 1:500 is included in the back pocket.

The plan shows that drill holes on the North Zone will consistently deviate to the west amounting to a relative displacement of - 15 metres from the horizontal, depending on the depth of the intercepts.

GREEN WEATHERED BASALT

Fine-grained basalt, weakly chloritic and calcitic. Rock is schistose andleached. Low core angles range from 0-10 to the core axis.

ALTERED VARIOLITIC BASALT (FLOW TOP BRECCIA)

Fine-grained, greenish-grey, weakly carbonated basalt 1s fairly massive andappears to be variolitic in nature and pillowed as well. Rock is stillweakly chloritic but calcite alteration increases with depth. Occasionalbarren carbonate veins (calcite) with little quartz. Local large fragment isbleached and saussuratized. Basalt contains dark-grey alteration zones overnarrow sections which appear to be composed of minor graphite, chlorite.calcite or some local Po. Lower contact is arbitrary.

38.7 m 1 cm wide calcitic band with 15* combined Po 4 Cpy at 100 tothe core axis.

88.4 - 89.7 m Calcitic alteration zone, minor quartz. Section contains 4tcombined Py, Po 4 Aspy. Foliation is about 30 to the coreaxis. (True width of zone is much less than indicated).

102.4 -102.9 m Narrow band of semi-massive Po, little Py 4 Cpy in calciticmatrix, at low angle to the core axis.

CARBONATED BASALT

Fine-grained green calcitic carbonated rock. Basalt appear to be pillowed andmore massive than In unit above, fragments and varioles appear to be mostlyabsent or else they are more obscured here because of the higher degree ofalteration.

Rock is medium-grained and green in top h o f section, changing to fine-grained greyish-green, weakly carbonated basalt in the bottom 15. Fractures are chloritic, a coarse quartz sweat with cubic pyrite occurs near the bottom.


Grey, fine-grained basalt, likely being our pillowed flow top breccia. Calcitt carbonate alteration Increases downhole showing some isolated barren quartz- carbonate stringers or sweats with a little Py in their walls. Fragments are easier discernable with depth and there rock is usually bleached to a lighter grey. Carbonatedbasal t becomes rather massive and is of medium-grain in bottom 15 m.

33.8 - 34.8 schistose broken core

- 39.4 oxidized fracture at 450 to the core axis.

- 42.4 as above, oxidation next to 3 cm wide quartz-carbonate vein with some pyrite, at 45 to the core axis.

- 43.8 as above - no quartz.

- 50.3 9 cm wide oxidized quartz vein at 500 to the core axis. No sulphides.

DESCRIPTION

CARBONATED AND MINERALIZED MI VEIN ZONE - VG

The indicated broad width of this zone is due to silicified hangingwall rockwhich is included here. The main mineralized and gold-bearing zone is pro bably around 1.5 m in width.

Calcite-carbonate alteration changes to ankerite (dolomite) in the quartzvein and immediately below it.

102.50 - 107.3 silicified wallrock. Numerous foliated quartz stringers-sweats or narrow veins. 1-23! coarse Py-cubes or littlefine Py t, Po. Minor Aspy in bottom ^ ra.

107.3 - 108.3 VG - Main MI quartz vein. Grey to milky-white quartzshowing 11 specks of free occurring gold along a vein'length of 30 cm. Vein is flecked with fine muscovite mica.ankerite or brown tourmaline. Py is about 2S, Po is 0.5J!and only very minor Aspy in the vein itself. Some Aspyoccurs at the foliated bottom contact together with one finespeck of gold.

DARK-GREY CARBONATED FOOTWALL

Highly altered, dark-grey carbonated rock. Pervasive graphite (?) dolomite-calcite-hydromuscovite alteration. A 0.5 m long foliated section right belowvein shows foliation running parallel to the core axis. Minor carbonatedstringers and quartz, add coarse cube of Py.

GREY CARBONATED ROCK

Fine-grained carbonated rock as above. Calcitic constituents increase. Colouragain becomes darker grey near the end with an apparent increase of quartz-carbonate sweats and stringers - now less calcite. Very minor local specksof Py. Schistosity is from 30 - 40 to the core axis.

ARGILLITE AND GREYWACKE

Intermittent argillite and greywacke interbeds showing Individual contactsfrom 20 - 32 to the core axis, i.e. hole is going down-dip. Argillite bedsare composed of very fine-grained silt-like materials, moderately bedded;colour ranges from grey to darker grey, the latter may be due to minorpervasive graphite.Greywackes are composed of fine, medium and locally coarse-grained polymicticrocks showing local inclusions of argillite. Colour is greenish-grey. Indi vidual argillite-greywacke contacts are usually sharp and well defined butlocally they are ragged or flame-like into the greywacke*. Leached quartz- .carbonate bands, minor local Po. Bottom contact at 20 to the core axis.

- 16.5 Ragged argillite-greywacke contact, graded bedding in grey wacke indicate tops are up-hole i. e, south.

MASSIVE GREYWACKE

Grey, fine to locally medium-grained rock has the appearance of alteredleucoxene basalt. Detrital coarser material are grains of quartz, feldsparsand lensy inclusions composed of a light grey, fine-grained material. Rockcontains some minor disseminations of Py S Po, The only other features arenarrow barren quartz-carbonate bands which cross-cut rock near 60 to thecore axis and some small angular inclusions of a finer grained rock in bottom3 metres.

ALTERED GREYWACKE AND MINOR ARGILLITE

Rock is schistose and calcitic to 84 m with minor dark-grey, massive beds ofargillite. This is followed by altered fine-grained greywacke which may bederived from fine volcanic tuffs or ash, rock is more massive than on top ofsection. Some pervasive alteration and discolouration is due to intermittentcross-cutting quartz veins or stringers showing minor Py or Po in the walls.Section shows only minor bedded materials.- 82.0 Schistosity over printing bedding at 700 to the core axis.

94.7 - 97.7 Widely spaced barren quartz stringers and veins, minor Pyin the walls.

was ground in broken sections. No sulphides or quartz veins.

99.0 - 102.0 Barren white quartz veins in oxidized carbonated rock.


Fine grained, greenish-grey basalt, weakly schistose and carbonated throughout.

Rock is intermittently variolitic down to 117, Om, small varioles have blurred

outlines and are of a light green colour. In addition, rock shows some

occasional large clasts of same light green colour. Orientation of varioles

Or clasts show alignment with schistosity at 60 to the core axis, Pervasive

alteration minerals include calcite, dolomite, chlorite and light green mica,

the latter accounts for the bleaching of varioles and clasts. 2X coarse and

fine Py near bottom associated with carbonate stringers.

ALTERED AND WEAKLY GRAPHITIC BASALT

Fine grained, greenish-grey to dark-grey rocks shows weak but pervasivegraphite and calcite contents. Basalt may be tuffaceous as there are someminor bedded sections dipping at 65 to the core axis. Widely spaced quartz- carbonate stringers or sweats give cause to some coarse aggregates of pyrite Bottom contacts with greenish-grey altered basalt is sharp at 45 to the coreaxis and there is 0.52S fine pyrite associated with quartz-carbonate stringers.

121.1 - 121.3 Quartz-carbonate stringers, some coarse Py.


Fine grained rock is greyish-green and weakly carbonated (calcitic alterationwith light green muscovite mica). Alteration increases in the lower Jj,minor bedded and stretched clasts begin to appear. There is the odd narrowquartz-carbonate band with some coarse pyrite.

MINERALIZED ALTERATION ZONE

Altered fine grained rock appears to be a tuffaceous basalt. Weak butpervasive graphite alteration gives this rock a grey to locally darker grey colour. Section contains from 5 - IDS Py as fine or coarse cubes. Somefine cubic Py forms streaks of massive Py in association with patches ofmassive brown tourmaline or with white dull quartz veins, containing abundantgrey calcite which is locally coarsely crystalline. (No Aspy or differentsulphides).

Carbonate and chlorite have developed preferencially along fractures ard fragment rims. - Fracturing of rock 1s locally prominent and approaches t?-* degree of brecciation. This appears to be due to a late state tectonic event.The core from 27.50 to 76.30 is strongly affected by weathering because It 1s highly fractured so close to the bedrock surface. The consolidation of the rock increases with depth as 76.30 metres is approached.The fragments are lithologically the same as the fine g ra f nad matrix.102.40 - 102.67 Quartz Vein.

NOTE: Alteration in this moderately fractured unit is caused by chlorite, minor local pervasive graphite, few minor quartz-carbonate stringers (calcite) with very minor local sulphides as described above. Unit is not pervasively carbonated but the calcite content increases in the weakly graphitic sections below 290.5 m.

Core angles given aboye do not reflect bedding angles, some rare reliable beddi.ng angles can be found locally in connection with small clasts, which are oriented from 60 - 70 to the core axis.

Greenish-grey massive basalt, chlorlte-calcite alteration. Minor quartz -carbonate stringers with a little pyrite. Bottom contact 1s sharp at 30 tothe core axis.


Grey, altered fragmental rock becoming progressively stronger carbonateddownhole showing some sporadic cubes of pyrite and minor quartz-carbonatebands or sweats. Calcitic carbonate alteration. Minor tight oxidizedfractures near bottom.

CARBONATED AND MINERALIZED BROULAN REEF VEIN (BRI VEIN)

This 1s the old Broulan Reef vein which is being intersected for the firsttime by Canamax drilling. Vein material is spread-out over a wide areawhich 1s due to the fact that the drill hole is not cutting the vein atright angles.

This mineralized vein zone is a grey carbonated and fragmental unit, Inter mittently silicified, pervasive hydromuscovite mica occurs throughout,carbonate alteration is now dolomitic. Entire section contains 2-33S pyriteand local appreciable very fine Aspy. Pyrite occurs in aggregate - or cubicform, subhedral Py in snowflake crystal clumps. Fractured sections arestrongly oxidized, some vein material was ground near 48 m.

44.0 - 44.7 Silicified section, fine Aspy and some tourmaline near the top.

44.7 - 46.2 Grey carbonated rock, minor quartz-carbonate sweats, 0 - 5Xfine snowflake pyrite.

CARBONATED MI HORIZON

The actual MI vein appears to occur at the top of section but the entiresection will be sampled as there are some sporadic quartz veins with minorPy at different locations, therefore, any Au mineralized branch-veins may getpinpointed by assays. The dolomitic carbonate alteration with pervasive micadevelopment extends nearly to the bottom of this section where it is replacedby calcitic alteration. This in Itself usually marks the end of any mineral ization.

SUMMARY OF BELL CREEK UNDERGROUND EXPLORATION PROGRAM

To Accompany 198fr OMEP Submission

INTRODUCTION

The objective of the Bell Creek underground exploration

is the in situ examination of the 'A 1 horizon of the North

Zone on four levels. Current plans call for drifting on the

drill*-indicated economic portions of the deposit on the 60,

120, 180 and 240 metre levels, and raising between the

levels. A sampling regime consisting of a combination of

face, back and muck samples will be used to compare grade, and

thereby determine the economic viability of the deposits.

WORK COMPLETED

In May 1984 a contract was awarded to Patrick Harrison

and Company to erect a mining plant, sink the shaft to 260

metres, cut stations on four levels and carry out certain

specified lateral work. The contractor commenced work in

3une. Copies of Progress Reports from R. MacPhail P. Eng. are

attached along with a graphic presentation of the actual

versus the proposed work schedule. Photographs showing

changes at the site between November 1983 and November 1984,

as well as the surface plant are attached.

r-2-

COMMENTS

The Bell Creek underground program is proceeding on

budget but is somewhat behind schedule. An irregular bedrock

profile in the area of the service building resulted in more

rock work than was anticipated. This coupled with a late

start and a delay in delivery of the prefabricated building

resulted in a two month set back in the planned work

schedule. Barring unforseen delays it may be possible to make

up some of the delay during the sinking and crosscutting

sequence now in progress.

1984 the work on the by Patrick Harrison and

MINE HOIST: The brake paths were precision ground and the new..... wooden brake shoes were arced to fit. The hoisting ropes can be installed as soon as the L... Lilleys are calibrated and after the mine inspector and hoist consultant have the brake deceleration :c readings to their satisfaction, hopefully by January 3rd.

. T:M ........., V A.'.'C ......__

ELECTRIC POWER: The electrical sub-contractor and his crewhave spent all of the month of December installing the hoist and hoist signal electrics. Throughout most of this time they worked on two shifts, 5^ days per week. Patrick Harrison and Company Ltd. have installed their two Sullair, screw-type, compressors and augmented the 600 volt power supply by installing a 500 K.V.A. dry transformer in the shop area. Even since it was energized, our used 1000 K.V.A., 2400 to 600 volt, transformer has emitted a loud vibration hum and .we may have to have the supplier replace this unit.

The electric cables for the yard lighting, the parking lot, the ventilation raise and the industrial water pump have been buried on surface, but none of these facilities have been completed.

SERVICE BUILDING AND ACCESS TUNNEL_______________ The shower and toilet facilities are complete and the hoistroom and the permanent office are finished. The contractor has erected a temporary wall to separate the miners' clothes dry from the shop area and enclosed an office space for his clerk and engineering technician

- 2 -

All of the propane heaters and one of the three electric floor heaters are operational. Most of the permanent lighting panel is connected, and when the light fixtures are delivered and installed, the service building construction will be finished.

In the access tunnel the lights, doors and heater are installed and all of the electric lines and the various pipe lines have been run and connected. A second pair of cable portholes had to be put in the wall when we learned that there was only one cable attachment hole in each hoist drum.

HEADFRAME: Except for the east side of the headframe tower, all of the painted steel cladding is in place. The roof and all four walls are cladded on the upper portion of the penthouse. Until the shaft bottom has been sunk another 80 to 100 feet, the east wall of the tower will remain open to allow for the blasting percussion. The ore slide above the bin and the shaft sinking dump doors, complete with pistons and controls, have been installed.

After the hoisting ropes are installed the bucket and sinking crosshead will be installed in the north hoisting compartment which will permit the attachment of the guides and chairs in this com partment. The sinking clam will have to remain in the south hoisting compartment until the shaft has been deepened enough for several timber sets to be installed.

ORE 6 WASTE BINS: The ore chutes have been installed in the bottom of the ore bin, the entry to the south side of the load out has been partition off and temporary wooden doors have been installed on the north side. Lights, heaters, and the permanent rollup door on the north entry are pending. The availability of welders and mechanics has delayed the building of the bin house on top of the the reinforced concrete ore and waste bins. This bit of construction should not interfere with the sinking operation. In the meantime the waste rock will be dumped through the bin and chute directly onto the truck.

During the month of November 1984 the work on the development of the Bell Creek Project, by Patrick Harrison and Company Limited, was as follows:

Mine Hoist: The auxiliary air compressor for the hoist is connected to th,e hoist braking system, and all of the safety valves are in place and connected to their air lines. The main 600 volt electric power lines to the motor and the various auxiliary power lines are being installed. When the hoist can be turned the brake paths will be precision ground and the new brake shoes arced to fit.

Electric Power: All of the electric power in use at the site is being furnished by the main sub-station. The power lines to the parking area, the yard lighting and the water supply pumps are being run and buried. Until recently the electric power on the site has been distributed through surface lines from the contractor's Diesel generator.

The new hoist panels and resistance grids have been installed in the hoist-room and are being connected to the 600 volt power supply.

Service Building and Access Tunnel: Except for the glass for the windows and man doors, the outside of the building is complete. Inside, the divider wall between the hoist-room and the shop is half built and the walls for the office and bathroom have been framed. The propane unit heaters are in place, and most of the gas lines have been run. In the access tunnel, the concrete floor has been laid, the potable water line and the propane gas line have been laid between the stairway and the mine shaft. There are no permanent lights in the access tunnel or in the service building, in fact none of the lighting wires have been installed.

- 2 -

Air Compressors: The contractor has brought two rotary screw type air compressors to the site, and because of their size and the sound they generate, he has chosen to install them in a temporary building against the outside north wall of the service building.

Headframe: The main structure has been completed, aligned and the bolts tongued. The sheave wheels have been aligned and bolted down, the manway completed, and the lightning rod and the flagpole, with an aircraft warning light, are installed above the roof. The cladding of the headframe tower has commenced with the west side being covered from the roof of the collar house up to the lower sheave deck. Until the deck house roof is installed and the shaft deepened, the east side of the tower will remain open, but the north and south sides will be cladded to the penthouse roof. The collar house requires the hanging of the doors, the lights and the metal flashing around the eaves.

Ore S Haste Bins: The reinforced concrete walls are finished to height and after the ore and waste chutes and the skip dump slide are in place the deck house will be built to enclose the top of the bins. Until there are more definite plans for the road and the mill conveyorway, the loadout from the ore and waste bins will operate through a north door only and the south door opening will be partitioned.

Shaft Sinking Equipment: The blasting set is in place in the shaft collar and four tugger hoists have been installed around the collar. One to raise and lower the mucking clam, two to handle the moving of the blasting set and the fourth for general servic ing. The electric drive motors are wired and the hoisting ropes installed on all of these tugger hoists.

The cross heads and sinking buckets have been delivered to the site and the dump doors and sinking clam are to be delivered in a few days.

Miscellaneous: Lake Shore Inc. are doing an analysis of the steel head frame for the siemic and wind load conditions of this area. We require this for certification and as installed in the St. Louis, Missouri area the headframe was .designed for use^as.jjT,

structure^ and because the shaft was used for hoistingthe crossbracing extended right to the ground on all

four sides of the tower. For our use, we have to be able to move supplies and equipment on and off the cage and, therefore, we have to eliminate the crossbraces on one side of the tower, on the deck house side. Lake Shore will determine whether some reinforcing steel pieces are required for the certification in the Timmins area.

Mine Hoist:

Patrick Harrison has a mechanical foreman assembling the hoist, putting all the brakes and clutch linkages etc. together. When everything is in place and properly adjusted the final grouting of the motor base and the brake posts will be made. The delay in the delivery of the pre- engineered service building interfered with this hoist assembly work.

Service Building and Access Tunnel:

Angle-iron brackets were attached to the north side of the access tunnel and the 8 inch compressed air line was installed on the lower shaft of the brackets. An upper shaft will hold the electric wires for the headframe and the underground. With the laying of the concrete floor and the lighting, the access tunnel will be completed.

The frame for the service building has been erected, the large overhead doors were installed and the wall cladding commenced. Over the two bays, which house the hoist and the electrical switch gear, the roof lining was put into place to provide shelter from the weather and to permit working on these components.

Headframe:

A steel frame, 44 feet high was erected on the north side of the headframe tower to extend the shaft manway up past the collar house. When enclosed, this section will house the stairs up to the bin deck. From the elevation of the bin deck the headframe manway will extend up in the west side of the tower. At the end of the month one landing and two stairs had been installed for the headframe manway. As soon as the manway landings are completed the installation of the girts and the cladding will start.

At times the work on the upper portions of the headframe has to be stopped to allow the ore and waste bin construction to proceed on the ground below.

Electric Power:

The main sub-station is complete with the fence erected and the connection to the mine site end of the pole line made. All of the secondary switches and distribution panels are in place in the service building and their connection to the primary sub-station is in progress. The energizing of this sytem should be possible by mid month.

Potable Water Supply:

Potable water is being supplied to Harrison resident trailer at the site, but the pipe line to the headframe and the service building has not been completed.

Industrial Water Supply:

A two inch pipe line in an insulated box has been laid from the creek pump house to the shaft area. This line is heat taped also and will be extended across the road to the shaft manway.

The pump and pump line for the reclaimed water has not been constructed yet. This will require another small pump house and an insulated pipe box.

Ore and Wate r Bins:

The ore and waste bins are being constructed of reinforced concrete. To date the foundation walls and the floor for the bins has been completed. A form, 10 feet high, has been built and ready for the concrete to be poured, with this pour the bottom third of the concrete bin walls will be ready for the forming and pouring of the next two lifts.

Telephone:

The permanent telephone line has been brought to the mine site and from a junction box temporary lines have been extended to the con tractors' two office trailers and to the superintendant's resident trailer.

Service Building and Access Tunnel:

The backfilling and compacting of the granual fill was completed, the installation of the reinforcing grid wire and it's connection to the electrical bus bars was made, which permitted the concrete pour to form the finished floor slab. The electrical bus bars will carry off-peak power to heat the service building.

Except for the finish soil topping, the access tunnel is com pletely buried in granular compacted fill, and the installation of the concrete floor will complete the access tunnel.

- 2 -

Headframe:

With all of the main frame of the headframe standing, it would appear that the headframe erection was almost finished, in reality it is about half done. Most of the connections are only partially bolted and after the remaining crossbraces are added the structure must be aligned and all of the bolts torqued. Additional pieces must be added for the guides, the skip dumps, the manway to the top, and the girts for the cladding on the outisde of the tower.

Our hoist and skip arrangement is different from that used in Missouri and the sheave deck had to be refabricated. This was accomplished by rearranging the steel components from the original two sheave wheel decks. Some new steel had to be fabricated to complete our hoisting compartment configuration.

Sewage Disposal System:

The concrete septic tanks were set in place all of the piping for the inlet and discharge was completed, inspected, approved and buried.

Settling Ponds:

The two settling ponds were completely built, the overflow wells built and the 6 inch inlet and discharge pipes installed. The return water pumping system remains to be constructed.

Industrial Water Supply:

In order to get the 20 ft length of 4 ft diameter culvert pipe in the proper position, a second excavation was made which permitted the top of the culvert pipe to be lowered to the road top elevation. A precast concrete collar was installed, completing the suction well for the industrial water. Work began on the building of a l x l foot pipe box to house the 2 inch industrial water supply line.

Potable Water Supply:

The 12000 gallon potable water tank was anchored to the bedrock and buried immediately north of the pumphouse at diamond drill hole MH 81-6, The 25 gal. per min. suction pump will supply water to the large storage tank, and a domestic type pressure pump will distribute the potable water to the mine site buildings.

Ma i n sub-station:

The tower and the primary 3750 K.V.A. transformer was transported to the mine site and installed on it's foundation. A ground grid with a resistance of 5.0 ohms was installed to the northeast of the sub-station and when the surrounding fence is built and the incoming and outgoing electric cables attached the sub-station will be ready to be energized.

Shaft collar: By the end of the month the forming for the shaftcollar and access tunnel walls was completed and when poured will complete the shaft collar except for the ceiling of the access tunnel at the shaft compartments. This ceiling area requires a steel support set and will be poured as part of the deck house floor.

Hoist foundation: The forming, reinforcing and pouring of the concretehoist foundation was completed and after the initial curing period the bearings for the hoist main shaft will be set and grouted in place.

- 2 -

Headframe piers: After pouring a block of concrete in the form of a 5 ft cube for a rough footing, the pyramidal piers for the headframe back legs were formed, reinforced and poured. The four legs of the headframe tower rest on the concrete shaft collar.

Service building and access tunnel: The sectional steel culvert pipe that forms the access tunnel was bolted together and when it is alligned and all the bolts torqued the back filling with granular fill can begin. All of the back fill will be compacted in about one foot lifts and in the northeast corner about 12 feet of fill will be required.

At the west end of the access tunnel the steel pipe is attachedto a rectangular concrete box which will house the stairs leadingup to the shop floor. At the east end the access tunnel pipeattaches to an extended north wing of the shaft collar.

Sewage leaching bed: The granular fill for this leaching bed has been trucked to the site and an area about 100 ft square has been built to a depth of about 5 ft. This area is required to permit the laying of the 500 ft of pipe for the sewage disposal system. The concrete septic tank has been delivered to the site, but the pipe laying and tank installation has not been started.

Settling ponds: The granular fill to build the first half of the wall for these two settling ponds has been brought to the site and laid in place.

Industrial water supply: Some of the large pieces of rock from the road levelling was deposited on the west side of the main culvert at the creek and a 4 ft culvert pipe with screened inlet holes was stood on end to form a suction wall for the industrial water pump.

Main sub-station: The footings, piers and the top slab for thisfoundation were poured and the fill compacted around it.

Hoist refurbishing: A great deal of time was taken with the machineshop work on the main shaft and the clutch hubs and other refurbi shing work had to be delayed until the final measurements of the main shaft were available; such as the finish machining of the drum bushings and the main bearings. All of machine shop work is now completed and most of the final assembly has been made.

Hoist Electrics: The new electrical controls are ready and as soon asdrawings for the mine inspection approval are received we will have the electrical controls delivered. We commissioned Walter Dow S Company to provide us with approved drawings for our sub station installation and now they are to draw up the hoist control schematics.-'A! Higgins of Can-Test brought his test equipment from Sudbury to ultra sonically test the pins and rods of the hoist brakes and to magnetically inspect the brake paths and other components of the hoist that were not tested in Red Deer Alberta before we purchased it. Even though the brake and clutch pins are all new, ultra sonic testing is necessary before the hoist can be commissioned and thereafter every twelve months.

Road on the site: The drilling and blasting to lower the western extension of the road was completed and grading of the finished extension started. The excavation of the rock was required to prevent the run off water from accumulating at the shop doors.

Shaft collar: Except for the blasting of a few pops all of the rock work above the 285 metre elevation was completed during the month of June. In the month of July the 7.8 x 3.6 metre excavation was taken down 4.8 metres and an additional 6.83 x 2.80 metre excavation was taken down 2.44 metres. The present shaft bottom is at an elevation of 277 metres and the airtrack holes extend down to the 267 metre elevation. In the larger top portion of the excavation the walls were drilled for #8 re-bar dowels and this portion of the shaft collar was formed and poured with reinforced concrete.

- 2 -

Headframe piers: The bedrock was uncovered, washed and dowel!ed pre paratory to pouring rough footings for the back leg piers. The headframe columns will rest on the concrete shaft collar.

Service building and access tunnel: In preparation for this structuresome rock excavation was needed for the west end of the access tunnel and a shaving off of about 0.3 metres in the southwest area. Most of the broken rock from here and from the road excavation will serve as fill to support the floor slab for this building.

An greement has been made with the contractor for an extension of 3 x 12.2 metres to the north side of this building to house the main secondary electrics. The access tunnel which extends from the west end of the service building and below the floor slab will have reinforced concrete walls and floor at each end and the main, or center section, will be a corrigated steel culvert. To more or less level the area where the hoist foundation will be constructed, a form was built, the bedrock was washed and dowel!ed and about 37 cubic metres of concrete were poured.

Hydro electric power: The local power commission has completed theirrehabilitation of their power line and made the connect ion to own line.

Telephone: Canamax has prepaid the construction costs for the permanent telephone line to be built from Florence St. in the east region of the city and construction will commence as soon as the material arrives.

The main sub-station: The dismantling of the Langmuir sub-station has beencompleted and the components will be set up at our mine site when the concrete base is ready. Patrick Harrison's crew has taken on the work of building the sub-station foundation.

Hoist: The main shaft and clutch hubs will be shipped from the Toronto machine shop as soon as the new keys are pressed into the keyways. All of the other mechanical components are ready for the new installation. Dominion Electric has been contracted to supply us with an up to date refurbished electrical control system which will include a new consul and dynamic braking.

Composite B: 6.34 g/t Au

Several samples of both composites were amalgamated prior to cyanidation

tests to remove the salting effect of free gold. The amount of gold recovered by

amalgamation from Composite A ranged from 56-72 7. and from Composite B ranged

from 48-72 7..

2. Gravity Concentration and Magnetic Separation

The recovery of gold by gravimetric methods was investigated. A sample

of each composite was ground to 53 7. minus 200 mesh and fed over a laboratory

Wilfley table. The table concentrate was cleaned on a Mozley mineral separator.

The Mozley table concentrate was further upgraded by removing the magnetics in a

Frantz magnetic separator. The results are summarized in Table No. 1.

A mineralogical examination was performed on the magnetic and non-magnetic

fractions of the cleaned gravity concentrate from test No. 190 (Composite A).

Essentially all the gold in the non-magnetic product was free whereas over 90 *l, of

the gold in the magnetics was present as middlings. The size of the free gold varied

from 3 to 70 urn. The results of a grain count on particles in the non-magnetics

showed that 84 7, of the particles were non-opaques, 11 7, were pyrite and 5 7, were

arsenopyrite or marcasite. Over 80 7, of the sulphides'were liberated. These results

suggest that it should be possible to produce a higher grade gold concentrate by

gravimetric methods. Cleaning of the gravity concentrate in the laboratory was

limited by the size of the sample.

Summary - Continued

3. Direct Cyanidation Testwork

The effect of the following parameters on the recovery of gold from

Composites A or B were investigated: fineness of grind, cyanide concentration,

retention time, preaeration, pulp density and creek water. All tests were conducted

in bottles on rolls. In tests 108-119, the variation in the residue assays indicated

the presence of free gold. These residues were amalgamated and reassayed in

triplicate to determine a residue assay not affected by the presence of free gold.

It is the average of these assays which is included in the tabulated results. The

feed to tests 121-128 was tabled prior to leaching, and the table concentrate was

amalgamated. The amalgamation and table tailings were combined for cyanidation

tests. In all subsequent tests, the ore was amalgamated and the amalgamation tail was

used as feed to the leach tests.

- 6 -

SuWmcnary - Continued

3.1.Effect of Fineness of Grind

The fineness of grind was varied from 53 7, to 87 7c minus 200 mesh to

examine its effect on gold extraction from Composite A. The sample was aerated

for 6 hours prior to leaching. The cyanide and lime concentrations were maintained

at 0.5 g/L NaCN and 0.5 g/L Ca(OH)2 respectively. The results are summarized in

Table No. 2.

. Effect of Cyanide Concentration

Tests were conducted on Composite A in which the cyanide concentration was

reduced from 0.5 g/L NaCN. Again, the samples were amalgamated and the tailing was

preaerated for 6 hours prior to the cyanide leach. The results are presented in

Reducing the cyanide concentrate below 0.5 g/L NaCN led to higher residue

assays and a lower extraction of gold. The results from earlier testwork showed that

the difference in fineness of grind in the range shown above did not affect the

cyanidation results and therefore could not account for the increase in the residue

assays.

3.3. Effect of Retention Time

The effect of increasing the retention from 12 to 36 hours on the recovery

of gold from Composite A was investigated. In tests 108 to 116, the samples were

preaerated for six hours before the cyanide leach. The cyanidation residues were

later amalgamated. The residue assays given in Table No. 4 are those obtained after

amalgamation. The recoveries and calculated heads are based on these assays. In

tests 121 to 145, the ore sample was amalgamated before leaching. The reagent

concentrations in all tests were 0.5 g/L NaCN and 0.5 g/L Ca(OH)z.

3.4. Effect of Preaeration

The effect of preaeration on reagent consumption and gold recovery was

examined. The preaeration time was varied from Q to 24 hours. The cyanide

concentration was maintained at 0.5 g/L NaCN throughout the 24 hour leach period

and the lime concentration at 0.5 g/L Ca(OH)2 during prearation and leaching.

The results are summarized in Table No. 5.

Preaeration had no significant effect on the extraction of gold after

24 hours, however, the addition of a 6 hour preaeration stage did reduce the

consumption of cyanide. Extending the preaeration time from 6 to 12 hours further

reduced the cyanide consumption in the tests conducted. Because of the range of

consumption figures seen in other testwork, further tests would be required to

quantify the effect of extending the preaeration stage beyond 6 hours. The fineness

of the material entering the preaeration stage will also have an effect on the lime

required and the absolute cyanide consumption. An additional benefit from the

preaeration may be the reduced iron concentration in the cyanidation circuit.

3.5. Effect of Pulp Density

The effect of pulp density on the cyanidation recovery of gold from

Composite B was briefly examined. A sample was ground to 84 7. minus 200 mesh and

amalgamated to remove the free gold. Cyanidation tests were conducted on the

amalgamation tailing at various pulp densities. In each test, the sample was

preaerated for 6 hours then leached in a 0.5 g/L NaCN solution for 24 hours.

3.6. Effect of Creek Water

Parallel cyanidation tests were conducted on Composite B using tap water

and the creek water sample provided. The test charges were ground to 77 7o minus

200 mesh and amalgamated. Each amalgamation tailing was split into two parts to

run the parallel leach tests. Each sample was preaerated for 6 hours followed by a

24 hour leach maintaining 0.5 g/L NaCN. The results are given in Table No. 7.

4. Intensive Cyanidation

Tests were conducted on Composites A and B to investigate the recovery of

gold from a gravity concentrate by intensive cyanidation. The effect of regrinding

the concentrate prior to leaching was briefly examined. The gravity concentrate

was agitated in a covered plastic jar using an Agitair cell. Oxygen was circulated

to the sample throughout the leach period. At the beginning of the leach, 30 g/L

NaCN was added raising the pH above 11. The results are summarized in Table No. 8.

Gold recoveries in the cyanidation stage of 98 7, were achieved from both

composites. Regrinding of the concentrate was essential.

The degree of regrinding required to obtain a high recovery was not

determined. The results from test No. 189 suggest that a retention time less than

24 hours may be sufficient. Further testwork is required to optimize this process.

5. Zinc Precipitation Testwork

The precipitation of gold from a pregnant solution using zinc dust was

briefly investigated. The cyanide concentration of the pregnant solution was adjusted

to 0.5 g/L NaCN. The solution was deaerated with nitrogen. Lead nitrate and zinc

dust were added and the solution was agitated with the nitrogen gas. It was then

filtered while maintaining an oxygen-free environment. The results varied. The

best results were achieved in Test No. 149. With a zinc dust addition 100 times

the theoretical requirements, the gold in solution was reduced from 2.34 mg/L Au to

0.012 mg/L which represents 99.5 7. precipitation. In other tests, the precipitation

was less efficient, possibly due to inadequate contact with the zinc dust.

6. Cyanide Destruction Testwork

Cyanide destruction tests were conducted on zinc precipitation barren

solutions from Composite A using the alkaline chlorination and SOa/aeration methods.

- 1A -

nary - Continued

6.1. Alkaline Chlorination

Two alkaline chlorination tests were performed on a sample of zinc

precipitation barren solution. Chlorine was added slowly as a 5 7, NaOCl solution

while maintaining the pH above 11 with lime. When the emf had stabilized, it was

assumed that the reaction was complete. Sodium arsenate was added to fix any

residual chlorine. The results are presented below.

By increasing the Cl/CN ratio from 7 to 10, the total cyanide level in

the effluent was reduced from 9 to 3 mg/L CN . The iron in the barren solution could

account for 1.5 mg/L CN as a ferrocyanide complex. It would not be possible to

reduce the cyanide below this level using this method despite increases in the

chlorine addition as the ferrocyanide complexes are not destroyed by alkaline chlorina

tion.

6.2. S0 2 /Aeration

The destruction of cyanide using the S02 /aeration method was also examined.

Tests were conducted in a baffled vessel with agitation provided by a mechanical

mixer. An 802/air mixture was metered into the solution. The pH was maintained at

8.5-9 using an automatic titrator to control the flow of a lime slurry. Copper

was added as a dilute copper sulphate solution.

In the initial tests, 50 mg/L Cu was added and the SOa/CN ratio was

varied from 3.2 to 4.5 g/g, with a retention time of 30 minutes. Under these

conditions, the cyanide level in the barren solution was not reduced below 43 mg/L CN,

Subsequently, sufficient copper was added to complex the free cyanide (assuming

Na 2 Cu(CN) 3 ) before- 'the S02 addition. In test No. 150, sufficient SOz was added to

provide a 4:1 SOa/CN ratio over 30 minutes. The total cyanide in solution was

reduced from 238 mg/L to 2.8 mg/L CN . Extending the retention time to 60 minutes

resulted in a barren solution analysing 2.3 mg/L CN . In a continuous test, test No.

158, twice the amount of copper required to complex the free cyanide was added. The

SOj/CN ratio was maintained at 6. The barren solution analysed 107 mg/L CNT and

68 mg/L Cu. A sample of barren solution was retreated for 30 minutes with a 4/1

SC-2/CN addition and no further copper addition. The retreated barren solution

analysed 0.25 mg/L CN and 1.8 mg/L Cu. The results indicate that it is possible to

reduce the cyanide content to acceptable levels using S02 /aeration method but further

testwork would be required to optimize the conditions.

7. Settling and Filtration Testwork

Settling and filtration tests were conducted on Composite B using samples

of creek water. The feed was ground to 77 'L minus 200 mesh and amalgamated before

further treatment.

7.1. Settling Tests

Tests were performed to investigate the effect of pulp density and lime

addition on the settling characteristics of the amalgamation tailing. A single

test was conducted on a sample of pulp after a 24 hour cyanidation. The results

9. Effluent Simulation

Tests were conducted on Composite A and Sample AG-B to simulate the barren

bleed and tailing. A l kg sample of each was ground to 77 "l, minus 200 mesh and

amalgamated. The amalgamation tailing was preaerated for 6 hours then leached in

a 0.5 g/L NaCN solution for 24 hours, filtered and washed three times with water.

The pregnant and wash solutions were combined and the gold precipitated with zinc

dust. This gold barren solution was used to wash and repulp a second cyanided

pulp. The repulp was followed by a fresh water wash. The procedure was used to

simulate a 2-stage drum filtration circuit. The solutions were combined and treated

by zinc precipitation to produce a sample of barren solution. The procedure is

outlined in Figure No. 1. More detailed flowsheets are included in the Details

SAMPLE PREPARATION

On April 2, 1984, five core and two reject samples were received at

Lakefield Research and given our Reference No. 8424478. Each of the core samples

was crushed to minus 6 mesh. Two separate head samples were riffled out of each of

the seven samples. The remainder of the samples were combined to produce Composite A,

Approximately 10 kg of minus 6 mesh material was cut out for Bond Work Index

determination. The remaining ore was further crushed to minus 10 mesh. Two head

samples were riffled out and test charges were prepared.

Composite B was prepared by combining the following samples:

Conditions:

To conduct a S02 7Air cyanide destruction test on a Zn precipitation barren solution.

The test was conducted in a 500 mL baffled beaker. The sample was fed with a Beckman solution pump. The solution was agitated by a mechanical stirrer. The pH was maintained by a ratiometer pH meter in conjunction with a titrator connected to a magnetic valve controlling the flow of the lime slurry. The SOa/Air mixture was controlled using a Matheson flowmeter. After the 30 minute batch (start-up), the circuit ran continuously for 90 minutes. The solution was collected during the last 30 minutes for analyses. The assay sample was filtered through a 0.45 vim micropore filter.

2.0 litres of preg. solution from Test 129 from which most of the gold had been precipitated with Zn dust.

Zinc Dust Precipitation

Purpose:

Procedure:

Feed :

Conditions:

Calculations:

To investigate the precipitation of gold from a pregnant cyanide solution by adding zinc dust.

The cyanide strength was made up to 0.5 g/L NaCN and the solution was poured into a separatory funnel. The nitrogen flow was adjusted between 70 and 80 with a 604 flow meter (glass ball) to deaerate the solution. After deaeration, lead nitrate and zinc dust were added to the solution. The reagents were mixed with nitrogen for the required contact time. The solution was then filtered through a micropore filter while nitrogen flowed through the solution.

To investigate the effect of using creek water on the cyanidation response of Composite B.

The thickened pulp from the settling tests was combined with the remaining amal tailings to make up the original 2 x l kg samples and the pulp density was adjusted to 30 7. solids with creek water. Both samples were preaerated for 6 hours with lime. The cyanidations were carried out in a single stage on rolls. After 24 hours, the two pulp samples were combined and an assay sample was removed. The remaining pulp was used for settling and filtration tests.
