) SUMMARY
Cal Graphite Corporation has purchased a contiguous
block of 16 unpatented mining claims situated in Butt Township,
ontario. The group covers approximately 665 acres and is
located 16 air-miles east of the village of Sundridge p Access
is excellent via paved and good quality bush roads.
The Cal Graphite Corporation property lies within
the Grenville Structural Province of the Canadian precambrian
Shield. This is an assemblage of highly ~etamorphosed
gneissic rocks between 2500 and 1250 million years old.
within these rocks are pelitic horizens containing graphite
) crystalline flakes which have historical production records.
One major graphite-bearing pelitic unit occurs on Cal
Graphite Corporation's Butt Township property. It has been
drill tested along an l800-foot strike length and dips at
o 40 to the southeast.
Drilling in 1981, and Cal Graphite's 1985 diamond
drill program, have confirmed and extended the graphitic
unit. The unit's true width varies from 46 to 243 feet. The
graphite flakes are coarse with 90.55 percent of the graphite
in an average concentrate being +100 mesh or larger. This is
a premium flake size in the graphite market and yields a
) premium price in the range of $1000 0 to $1200. (U.S.) per
ton of concentrate Q

-_ ... _--------------
As a result of combining the 1981 and 1985
diamond drill program we have established reserve figures
for the graphite-bearing unit. Proven tonnage (adjusted to
remove the waste rock) totals 6,200,562 short tons averaging
3.71 percent total carbon with another 1,824,709 short tons
averaging 3.49 percent total carbon in the probable cat~egory-
(adjusted to remove the waste rock). The graphite-bearing
unit outcrops at surface and is amenable to open pit mining.
The graphitic zone remains open along strike and down dip.
Recent deeper drilling indicates both width and grade
continuity down dip.
Stripping and bulk sampling have also been
completed on the subject property. Based on the 1985 diamond
drill and surface sampling results we have recommended
proceeding to a Phase 11, and possibly, a Phase 1x1 program
totalling $600,000.

While the graphite showings in Butt township have
long been known there is no record of previous work on the
property prior to 1979. In 1979 the Butt township propE~rty
was staked and the vendors optioned the ground to Vesuvius
crucible Company of pittsburg, Pennsylvania. Vesuvius Crucible
Company is a major U.S •. crucible maker and utilizes 6000 tons
of crystalline flake graphite per year o Vesuvius was apparently
seeking a good quality source of graphite for its own u!~e.
During 1981 and 1982 extensive exploration ~l7ork
was completed on the Butt township property, including
stripping, bulk sampling and the drilling of 20 diamond drill
holes, VC-l to VC-14B, totalling 3808 feet. All the holes,
except 14B, intersected extensive sections of griiiphite-bearing
pe1ite. Metallurgical tests were also performed for VeslUvius
Crucible at Lakefield Labs resulting in recovery of good
quality crystalline-flake with a carbon content in the 94-95
percent (LOl) range by simple flotation or flotation and
tabling. In March 1985 the ground carne open and was staked
by a new party.

Graphite in the Grenville has been known since 1845.
Limited production took place in 1840's, 1870-1896, and from
1896-1954 in Quebec and Ontario. The graphite was gene:rally
crystalline flake and it occurred in pelitic and semipelitic
beds within larger paragneiss sequences. The carbon content
is thought to be of primary sedimentary origin, the graphite flake
being formed during the metamorphism of carbonaceous shale,
siltstone and wacke. The semipelitic gneiss in the area is
generally dark grey and is composed of plagioclase, qual:-tz,
biotite and variable amounts of red garnets with frequent
hornblende. Pelitic gneiss has a faint violet colour caused )
by distinct pale pink or maUve garnets and it lacks hornblendes.

To date 22 diamond drill holes have been completed
totalling 5465 feet. These additional holes have been added
to Map 1 in the pocket of this report and onto the relevant
cross sections. The holes have consistently intersected
large thicknesses of graphite flake-bearing rock. In addition,
it became evident that the 1981 diamond drilling did not
penetrate the full thickness of graphite -bearing rock, but

example the true thickness of 130 feet shown in the 19B1
drilling for hole VC-12 was found to be 243 feet durin9 our
1985 drill program.
The majority of the 1985 diamond drill proHram
was intended as fill in holes, however the last hole (CAL-85-7D)
was a deeper hole intended to test the down dip continuity of
the graphitic zone o As can be seen from section VC-7 1:he
downdip continuity of the zone is excellent.
A large area has also been stripped in front of
holesVC-7 and VC-6A. At present a SOO-ton bulk samplE~ is
being completed o The bulk sample is being transported to
Sudbury mill facilities v There it will be milled in order
to assess overall graphite grade and to recover sufficient
graphite flake for testing by end-users to determine sllit-
ability of the final product for diverse uses. Several
additional areas were stripped to expose the graphite-1Jearing
unit at selected locations on the property.

CONCLUSIONS
These salient points can be made regarding Cal
Graphite's Butt Township property:
a) A graphite-bearing unit occurs on the ,subject
property along at least 1800 feet of st~rike length and the
unit dips at _400 to the southeast.
b) The graphitic unit is open both along strike
and down dip.
c) The graphitic rock is from 46. to 243 feet
wide (true width) as indicated by 1985 diamond drilling.
d) The graphite flakes are coarse with 90.55
percent of the graphite in the +100 mesh fraction.
e) Deeper drilling (Holes CAL-85-7D and
CAL-aS-lID) have indicated t:he graphitic unit had dip
continuity.
£) Based on 1981 and 1985 diamond drill programs
we can establish tonnage reserves of graphite-bearing material.
Proven reserves (adjusted to remove the waste) are 6,200,562
tons grading 3.71 percent total carbon, while probable

PEASE II is designed to bring the claims to lease
and to extend and upgrade the graphite reserves. It also
allows for test-milling of the Phase I bulk sample and
development of a generalized flow sheet. The graphite
concentrate from this test will be made available to various
graphite end-users for testing to determine the product's
suitability for diverse end uses. Phase II will allow survey
control necessary for engineering of an open pit design.
Provisions are also made for additional lab analysis of the
graphitic materialo
PHASE III will be dependent on the results ()f
Phase II; specifically the flow sheet, grades and marke1:ability
of the graphite. Phase III is intended to allow constrllction
of an on-site pilot plant rated at 250 tons per day. The

REPORT ON STRIPPING AND BULK SAMPLING
BUTT TOWNSHIP PROPE~
ONTARIO
In late September,. 1985 a program of overburden stripping
and bulk sampling was commenced. over Cal Graphite Corporation's
Butt Township Graphite Property. A 3 cu. yd. hydraulic shovel
was utilized for overburden stripping and all work was completed
on claim E.O Q 808729.
The purpose of the stripping program was to esi:ablish
the continuity, grade and inferred contacts of the Main or
East graphitic zone. The stripped overburden was dug from
the side of the hill and piled lower on the hill into a
primitive roadbed to allow the tracked hydraulic shovel· to
advance across the face. Map 1 in the Interim Explorat:ion
Report dated October 30, 1985 and amended January. 27, 1986
shows the stripped areas in blUe.
Finally, in October, 1985 the shovel reached a flat
area between diamond drill holes CAL-85-6C and CAL-85-8C where
a large graphitic area was cleared. The shovel then proceeded
to dip roughly 200 tons of graphitic bedrock. This material

EXECUTIVE SUMMARY
1.0 BACKGROUND INFORMATION
Cal Graphite Corporation owns a 23-claim, crystalline flake
graphite property situated 16 miles east of Sundridge village,
Ontario and 155 miles north of Toronto. Since the spring of
1985 the property has been the object of an intensive two
phase exploration program. Phase I (1985) consisted of the
completion of 22 diamond drill holes, stripping and bulk
sampling. Phase II (1986) added 34 dia~ond drill holes,
surveying, land clearing and overburden removal.
Two distinct flake graphite-bearing horizons were delineated
on Cal Graphite Corporation's property, the Hangingwall and
Footwall Zones. The zones aro very wide, possess excellent
quality, coarse crystalline flake graphite. Based on the
success of Phases 1 and II this mining feasibility report is
the final step to a production decision when taken together with marketing commitments.
This feasibility report is based on costs submitted by
contractors, Ontario Hydro, Bell Telephone, consultants and
other experts who have had input into the costs and prices.
The costs and prices are conservative and where more than one
cost or price was obtained the average was utilized. The
authors consider the quoted costs and prices are conservative
and may possibly be lower in practice.

2.0 ACCESS, TOPOGRAPHY AND ENVIRONMENT
The subject property is accessible via paved highway 518
East from Emsdale village for a distance of 10 miles to
Forestry Tower Road. Forestry Tower Road at mileage 9 is
located at McGuire Lake in the centre of the property and
on the graphite horizons.
The local topography is a rejuvenated peneplain area with
young V-shaped valleys and detailed relief up to 400 feet.
Overmature maple trees cover the slopes. Overburden is
usually less than 10 feet deep and consists mainly of silts
and clays with small boulder till areas. Drainage is
generally southward into the Magnetawan river and thence
westward as part of the Great Lakes Drainage System. Locally,
drainage is sluggish and water flow is low.
As with all mining projects some disturbance of the environ
ment is inevitable and it is anticipated that continued
communication with the involved ministries should allow
organized and stable evolution of this multi-staged mining
project with minimal environmental impact.
The following major developments are necessary for production:
Development Phase
(1) Selection and Preparation of Mill Site
(2) Selection and Preparation of Tailings Sites
( 3 ) Construction of New Bypass and Internal Property Roads (4) Diamond Drilling on McGuire Lake ( 5 ) Damming of Graphite Lake ( 6 ) Draining of McGuire Lake
@: CONSTABLE CmJSUL TlNG !NC~
Operating Phase
(1 ) Draining of Minnow Lake
( 2 ) Selection of Additional Tailings Sites
( 3 ) Preparation of Additional Tai 1 ings Sites ( 4 ) Construction of Underground Decline
( 5 ) Waste Rock Disposal Site
These developments would require government permits and
careful, detailed, discussions of each procedure prior t;o
implementation. Once development began it would be too
late to evoke radical changes in procedures.

3.0 GEOLOGY
Cal Graphite Corporation's Butt Township Property lies within
the Grenville Structural Province (1800 to 2500 million years)
of the Canadian Precambrian Shield. Specifically, the subject
property is included in the Parry Sound Domain, an assemblage
of layered paragneiss and minor amounts of marble. Metamor
phism has reached granulite facies and the former amorphous
graphitic sedimentary rocks have been transformed by
tremendous heat and pressure into crystalline graphite flakerich horizons.
Since the 1370's, when a provincial surveyor described the
presence of graphite on the subject property, the area has
been the object of a few feeble exploration efforts. In
the 1980's exploration and development work accelerated,
particularly since the spring of 1985 when Cal Graphite
Corporation acquired the property. Prior to 1985 a total
of 20 diamond drill holes (3808 feet) were completed on the
Hangingwall Graphite Zone. In 1985 Cal Graphite Corporation
completed an additional 22 diamond drill holes (5465 feet),
mostly on the Hangingwall Graphite Zone, but with minor
attention to the Footwall Graphite Zone which is also present
on the subject property. In 1986 Cal Graphite Corporation
drilled 34 diamond drill holes (75,744 feet) with a large
proportion of these holes testing both Footwall and Hang"ingwa7l Graphite Zones.

Both Graphite Zones consist of quartz-feldspar-crystalline
graphite gneiss host rocks which strike 045 0 and dip 40 0
eastward. The boundaries of each ore horizon are assay
rather than lithologic contacts. The waste rock is a
garnet-biotite-quartz-feldspar gneiss. Both ore and waste rock types are extremely competent.

Mine planning of the Cal Graphite orebody is restricted to
few alternatives due to topographical, geological and
environmental conditions. The orebody consists of the
Hangingwall and Footwall Zones that outcrop on surface in
the centre, but lie under lakes at the east and west
extremities. Permission to drain the lakes must be obtained
from the ministries of Environment and Natural Resources.
The orebody is designed to be mined in five zones as follows:
Zone Ore (Tons in 1000s) Mining No. Titl e Grade Ore Waste Method

TOTAL 2.42 29,452 25,456
In the first five years of production, it is intended to concentrate mining in the Hangingwall of the Main Zone at
baseline lO,OOON. This gives easy access to the Hangingwall,
that has a higher grade and a low mining ratio of waste:ore. Refer to sections 9,400E - 10,100E.
In year six, a ramp decline from the mill site will be driven
to be used as a conveyor gangway. Ore passes will be driven
into the ore zones and will be used to pass crushed ore from
the pit, to the conveyor and into the mill coarse ore bin.
The object is to reduce mining costs and offer an 2nvironmentally clean ore transportation system.
A production schedule for the total tonnage of ore and waste contained in the reserves is stated in the following table.

The final concentrate produced by this testwork represents
grade and flake size commanding premium product prices in
the graphite market. Extensive additional testwork is
necessary prior to final mill design. These tests would
establish optimum crushing method and size. It would also
establish the optimum flow-chart to produce each separate
product. In contrast to base metal or precious metal mills
this graphite mill must be able to vary the flake size and
carbon content to meet several product specifications. Thus
the final design must be versatile enough to fill all possible

8.0 CONCLUSIONS AND RECOMMENDATIONS
Cal Graphite Corpof'ation's Butt Township flake graphite
property is economically viable over a mining life of34
years producing graphite concentrate at a rate of 20,000
tons per year. Pre-production planning must start as soon
as a final production decision is reached and must include:
1. Environmental Approvals
2. Hydro Line Construction Planning
3. Tailings Dam Design
4. Lake Dam Design
5. Lake Drainage Permission
To maximize cost returns and mining layout efficiencies these steps are recommended:
1. start milling at higher production rate
in years 1 to 5 (See: Economic Table17) to maximize cash flow to payoff i nit i a 1 capital costs.
2. Design the mill for more than 3000 tons per day to allow additional product production in case of
larger market share. This would significantly lower operating costs.
3. Examine graphite market to obtain higher priced product lines which would lead to an even higher rate of return.

Cal Graphite Corporation's Butt Township property
consists of 23 unpatented mining claims covering approximately 1100 acres and situated 16 miles east of the
village of Sundridge. The property lies in the Grenville
Structural Province of the Canadian Precambrian Shield.
More specifically, the group lies within the Parry Sound
Domain; an assemblage of 1800 to 2500 million year old
paragneisses and minor marble. The Parry Sound Domain
rocks have been deeply buried and subjected to granulite
facies levels of heat and pressure. Ancient carbonaceous
argillaceous beds were metamorphosed to quartz-feldspar
crystalline flake graphite gneisses. Later retrograde
metamorphism resulted in the formation of carbonate as a matrix and binder for the rock units.
Two crystalline flake graphite-bearing horizons are
known on Cal Graphite Corporation's Butt Township property.
They strike 045 0 and dip 400 to the southeast. The units
are generally monoclinal but contain minor internal
ptygmatic folding and, in the area of sections 9500 and
960UE, a minor fold occurs in the hangingwall contact of
the upper unit. The two units are sub-parallel with the
main unit called the Hangingwall Zone and the lower unit
named the Footwall Zone. Surrounding and between the
graphitic gneiss horizons are garnet-quartz-feldspar
biotite gneisses. Generally speaking the Hangingwall Zone

is of slightly better grade material than the Footwall
Zone. The contacts of each Zone are transitional
assay boundaries. Garnet gneiss bands are found within
the Hangingwall Zone (comprising 2.6% of the unit) and
slightly more frequently within the Footwall Zone.
Similarly, graphitic gneiss bands are present in the
garnet gneiss rock, particularly within the interval of
waste rock between the two Graphite Zones. The Graphite
Zones vary in mineable widths from 60 to over 500 feet.
Both the graphite and garnet gneisses are extremely
competent but, due to a carbonate matrix, compressive
strength is roughly 11,000 psi for both units. It is
not expected ei ther rock type wi 11 cause tock support
problems, however the graphitic gneiss unit diSintegrates
over a short time due to chemical weathering. For added
pit support our pit design has 40-foot berms.
The graphite flake in Cal Graphite Corporation's
property is very large with 84.15 percent of the flakes +100 mesh size. The flake is easily freed from the host
rock during crushing and maintains its integrity during
milling. Gangue minerals are silica grains and biotite
flakes. Re-grinding and further cleaning remove these
gangue minerals because they are not contained within
the graphite crystal flake. These characteristics produce premium products for the world graphite market.

TONNAGE AND GRADE ADJUSTMENT FACTORS
Tonnage figures were calculated based on the results
of 76 diamond drill holes. The sections contain each
relevant diamond drill hole and its optimum mining width
and grade. Computer calculations were completed for each
intersection listing a variety of grades over selected
widths. Maximum mining widths were chosen by the authors
over grade considerations to facilitate future simple,
bulk mining methods in our design rather than costlier
selective mining methods. Each section was planimetered and
a volume factor of 13.2 cubic feet per ton of are and waste
was used for tonnage calculations. This volume figure was
established in several specific gravity tests in a laboratory.
Proven and probable tonnages were chosen based on:
1. Proximity of Next Diamond Drill Hole
2. Area of Influence of Proven Reserves for Each
Diamond Drill Hole Did Not Exceed 100 in
any direction.
3. Probable Reserves Fall Outsi of the 100-Foot
Area of Influence for Each Diamond Drill Hole.
Grades are given in percentage by weight of graphitic carbon.
The method of analysis is by double loss on ignition (L.O.I.).
An approximately 2-gram sample fraction of pulverized core
is weighed and placed in a crucible. The crucible is put
in an oven at 6500 C for 45 minutes, removed and cooled in
a dessicator. This first stage removes the low temperature
volatiles; such as sulfides, carbonates and water. After
re-weighing, the crucible is placed back in a 9500 Coven
for four hours, removed and cooled in a dessicator. Again
the sample was re-weighed and a calculation made of the
weight loss for the high temperature volatiles, in this
case graphitic carbon. This analytical method is widely

1. ACCESS AND ENVIRONMENT
The Cal Graphite Corporation property is located in
Butt Township, Ontario, and consists of twenty three (23)
contiguous claims, covering 1100 acres. Present access to
the property is east off Highway 11 on Highway 518 East at
the village of Emsdale. Proceed along 518 East for a
distance of 10 miles, turn onto Forestry Tower Road and
continue for 9 miles to arrive at McGuire Lake, the
approximate centre of the Cal Graphite property.
The topography of the area is rugged, with abrupt
ridges and valleys ranging from elevations of 280 feet to
405 feet above lake water level. Glaciation and erosion
have tended to round the hills and local glacial tills are
present. Most of the overburden material consists of clay.
The area is well treed with secondary and tertiary growth on
the highlands, consisting of mature and immature deciduous
trees, mostly maples. Heavy vegetation exists on the lower
slopes and wet marshy conditions in the valleys. Drainage
from the northern part of the property is in a northern
direction via a creek from Minnow Lake to Graphite Lake.
The southern portion drains in a southeastward direction into
the Magnetawan River system and eventually into the Great
Lakes.

A - PRESENT
This phase is underway, consisting of exploration
diamond drilling, tree cutting, overburden removal,
surveying, metallurgical testing and the compilation of a
"Feasibil ity Report" on the Cal Graphite project.
Ministerial permits have been obtained for the work in
progress and are due to expire in March 1987 , the conclusion date of Phase A. It was stated, that a copy
of the "Feasibility Report" would be made available to
the M.N.R., M.O.E., and M.N.D.M., when completed and
after expiration of the required period of confidentiality.
B - SHORT TERt~
It is anticipated that this phase will last until the
spring of 1988 and is the most important relative to environ
mental decisions that must be made.
Mutual concerns were expressed at the meeting and it was agreed that in order to save time ill reaching decisions
and issuing the required permits, close co-operation in the
planning to bring this operation into production would be
maintained. The number of items to be mutually resolved as
soon as possible are detailed as follows:
1. New Road Location
The present access road, Forestry Tower Road, is used
as a public thoroughfare by local fishermen and hunters. It
passes through the property and over the proposed open pit.
To divert this road around the pit should not be considered
an option, due to the proximity of blasting and possible
danger from fly rock.

It is recommended that a new road be constructed that
would go north off the Algonquin West Access Road for a
distance of four miles, and join up with the public access
road, west of the Graphite Property. Similarly, a road
will be constructed for internal property use along the
proposed tailings valley which would also meet the Algonquin
West Road. Gates will be located at both the start and end
of the present public road and at the junction of the newly
constructed tailings road to stop access onto the property.
The public would still have access around the property
towards the Tim Lake area via the four mile diversion.
The prevalence of all-terrain vehicles poses a continuing
problem to any type of industry operating in isolated areas.
Solutions to the problem can only be made by personnel
having detailed knowledge of the overall topography.
2. Tailings Treatment System
The tailings treatment system would consist of tailings,
settling and polishing ponds. The area that appears most
suitable runs southeast of McGuire Lake through a valley
that descends gradually to the Magnetawan River. The
intention is to construct dams at the south end of each pond,
and allow the treated overflow water to run successively
from each pond until it drains into the Magnetawan River
system. Analysis of the tailings resulting from metal
lurgical testing of the ore, do not appear to present an
environmental problem. Present provisions call for re-cycling
of process water from the tailings system back to the mill to
minimize the necessity to release any water into the
Magnetawan River System.

It is recommended that the dams be designed by geo
technical personnel specializing in that field and constructed
to their specifications. Waste rock, gravel and clay are
readily available and in quantity. It is appreciated that
this area will not contain the total tons of tailings
produced, and ongoing consultation will be required to
locate future disposal sites or modify the presently
selected area.
3. Mill Site Location
It is recommended that the mill be located in an area
at the head of the tailings treatment system, but at a
higher elevation. This will necessitate levelling and
cutting into the hillside, but this location will serve
two purposes. As all drainage from this area will tend to flow
into the tailings disposal system, it should eliminate any
possibility of adverse environmental daloage due to spillage
ilt the m; 11 .
ii It is intended to drive a decline ramp in a
north-easterly direction, through the hill, under the ore
body and ultimately transport the ore to the mill by
conveyor. This will reduce the surface truck haulage and
consequently the spills, dust and noise associated with it, resulting in a more efficient operation and greater enviY-on
mental acceptance.
4. McGuire Lake
As the orebody extends eastward from section lO,OOOE to lO,600E (Map 1), it passes under ~1cGuire Lake, a small
shallow lake whose maximum depth is about 20 feet at the
centre. Current diamond drilling shows a grade improvement
in the ore, and the zone open to the east. It is the ultimate

intention t o mine the McGuire Lake zone as a separate open

diamond d r i l l program from the frozen lake surface will be
necessary t o confirm the ore configuration, however rega.rdless
of d r i l l r e su l t s drainage of McGuire Lake i s necessary.
I t i s suggested that i t wou ld be possible t o dig and
i n s t a l l a culvert a t the southeast t i p of McGuire Lake, and
allow controlled drainage of the lake in to the t a i l i ngs
treatment system. (Refer t o Map 1 ) .

on the west s ide. (Refer t o Map 1 ) . I t i s suggested that Yinnow Lake, presently draining in to Graphite Lake, be
dammed a t the north end and a deep enough ditch be cut a t
the south end t o allow the lake t o be drained in th i s d i rect ion. Further def in i t ion d r i l l i ng will be requested

diamond drill program from the frozen lake surface will be
necessary to confirm the ore configuration, however regardless
of drill results drainage of McGuire Lake is necessary.
It is suggested thatit would be possible to dig and
install a culvert at the southeast tip of McGuire Lake, and
allow controlled drainage of the lake into the tailings
treatment system. (Refer to IYlap 1).
C - LONG TER~l
The long term phase starts with commen~ement of
nroducticn, possibly the spring of 1988. The present
mining plan calls for progressive, increasing tonnage,
starting at 1000 tons/day in the first year, and rising
to full production of 3000 toris/c,il.Y in U:e fourtn year.

property, from a shallow pit carried transversely across
the ore, for a period of five years or so. Concerns to
be addressed in this phase are:

During this period, permission will be requested
to drain Minnow Lake which is located above the ore zone
on the west side. (Refer to Map 1). It is suggested that
Minnow Lake, presently draining into Graphite Lake, be
dammed at the north end and a deep enough ditch be cut at
the south end to allow the lake to be drained in this
direction. Further definition drilling will be requested
in this area. When the lake is drained, the mining pillar

D - WASTE ROCK DISPOSAL
During the short and long term phases, a lot of waste
rock will be removed and used in the construction of roads, dams and berms. This will still leave a large amount of
broken waste rock to be disposed of during mining life. It
is anticipated that the ore will be developed and mined
from these independent open pits, and with proper scheduling
the first pit mined can accept the waste from the second and third pits. HoweveG regardless of how carefully scheduled the
mining sequence is,a large amount of waste rock will still
have to be placed on a waste stockpile. A location should
be designated that is environmentally acceptable, haulage
roads should be constructed lf required, and the area limed. ,
E - PIT AND PROCESS WATER
Water will not be generated as a result of mining,
but will occur in the pit as a result of the elements, rain and snow. It is intended to pump water from the pit via
pipeline to the mill and feed into their process supply.
The water used for processing in the mill should be
pumped from the settling pond back into the mill, used to process ore and returned to the tailings pond to commence the re-cycling.

3. Assume stripping and hydraulic removal of top soil
to be continuing during the fall of 1985 and to be completed
in 1987.
4. Assume a large tonnage of waste will be required
in 1987 to be used for roads and dam construction at McGuire
Lake, tailings, settling and polishing ponds. Other waste
berms will be required for water diversion. The design of
the dams and tailing treatment system would not form part
of this feasibility study.
5. Assume mining is by "open pit" method as far as
possible, with some ore below the pit being salvaged by
underground mining.
As soon as a decision is made to bring the Cal
Graphite property into production, further pre-production
work is required, classified into Administrative Preparation
and Site Preparation.

D. ROADS The present "Forestry Tower" access road runs
through the property and directly over the proposed open
pit. A new road will have to be constructed that will by
pass the mine site. It should be relocated to depart from
the Algonquin west road, near the Magnetawan River and run
NE, a distance of three miles to meet the Tim Lake Road.
The location of the road is envisioned to pass well east of
the mining operation and tailings fill system.
The road will require ~150,OOO tons of waste rock and
the cost is anticipated to be in the range of $590,000. The
road will be used to haul the bagged concentrate and will be
30' wide with a good gravel surface. The costs will be a

4. PLANNING
The mining of the Cal Graphite property ore-body is
restricted to few alternatives due to topographical, geological and environmental conditions. These constraints affecting mine planning and design are:
A. TOPOGRAPHICAL AND GEOLOGICAL
The ore body consists of two major zones, the Footwall
Zone and the Hangingwall Zone. Both zones come to surface
in the central area, but lie under lakes on the east and west
extremities. The east lake is called McGuire Lake and the west ~1i nnow Lake. (Refer to I"lap 1).
The orebodies dip to the southeast at an angle of about 40
0 and a large hill overlies the central zone.
The ore body has been separated into four distinct mining blocks:
1. t~ai n Block
2. McGuire Lake Block
3. Minnow Lake Block
4. Below Main Block (S.E.)
The reason for this configuration is that Block 4 is southeast of the Main Block and not amenable to open pitting due to excessive waste removal.
Blocks 2 and 3 are environmental concerns.

Blocks 2 and 3 lie under lakes that will require draining. The lakes concerned are Minnow Lake and McGuire
Lake and are both shallow. Minnow Lake drains northward
via a creek into Graphite Lake, and McGuire Lake is a spill
water lake from Graphite Lake that drains southeasterly into the Magnetawan River System.
Permission to drain the lakes and build a retaining
dam at the neck of Graphite Lake will be required from the
M.N.R. and M.O.E. This will in effect remove the lake and
creek mining pillars shown on all sections, allowing full recovery of ore. (Refer to sections and Map 1).

The design of the Main Zone open pit can be discussed
in detail, but the McGuire and Minnow Lake zones cannot be
planned until the lakes are drained and the geology of their
ore clearly delineated. Similarly, the method of extracting
the "Below r~ain Zone" should not be determined at this time
as actual mining may not occur until year 34.
1. Main Haulage and Pit Roads
The surface haulage road from the pit to the Mill will
be upgraded to accept 40 ton haulers. The pit haulage
road will start at the N.E. pOint of the pit and
decline at -10%, the maximum safe grade for winter
operations. A single haulage road of 40-foot width
~~ill be maintained, until the pit is mine~ to its
full width at lake water level. A return haulage
road will then be ~stablished to exit the pit at
the southeast end, closer to the mill. The roads
will be sanded in the winter (Dry Tailings) and a
barrier maintained on the open side of the roads.
The road will be extended to 50-foot widths on
curves and the downgrade reduced to -5%. The
contractor will maintain all haulage roads into and
throughout the pit for anefficient operation, They
are to be dressed using granular material, loaded,
dumped and spread by the contractor. He is also
responsible for plowing snow in the winter, oiling in the summer and keeping roads clean and free from spillage.
2. Benches
For the purpose of this feasibility study, the pit
slope is designed to include a much larger margin of
safety than may be required. Two 40-foot benches
should be drilled at -65 0, blasted and mucked. A
berm of 40 feet should be left from the toe of the ! , I I

Therefore a waste dump s i t e dec i s ion i s not required

second bench to the collar of the third. The
reason for this configuration, is that every 40-ft.
berm left is wide and competent enough for use as
either a road or clean out bench. The compressive strength of the rock is in the 8500-
11,000 P.S.I. range and should not present any
difficulty in drilling. The drilling pattern for a
40-foot bench can be as high as 9' x 6' in are and
waste usi ng 3" bits. Thi s waul d result in an average
break of 130 tons/hole. At full production of 6000
tons of are and waste, 1,835' feet of drilling/day
would be required on two shifts.
The ratio of waste to are calculated and used for
thi s study averages 1: 1. However, after the pi tis
started and the exposed faces proved competent, it is
conceivable that the slope angle could be reduced
with a resulting drop in the was~e tonnage.
Waste disposal is a cause of concern, given the
magnitude of waste to be store~, and a site will have
to be located and limed. In the pre-production and
first two years of production a total of 750,000 tons
of waste will be required for dams, roads and berms.
Therefore a waste dump site decision is not required
immediately.
The present mining schedule is based on mining
the Main Zone, phases 1 and 2, and then mining the
HcGuire Lake zone followed by the II1-innow Lake Zone.
In reality, if permission is obtained at an early
date to drain the lakes, it is recommended that these
two latter zones be mined before the Main Zone and if
the mining is complete they will serve as waste storage sites.

4. Crusher A portable crusher will initially be set up at the
mill site to crush to -6". Stockpiles of 25,000
tons of crushed and uncrushed ore should be maintained
at the crusher site as mill and crusher feed, in case
of delay in the mining cycle; e.g. snow storms,
ligh~ning storms or breakdowns. Later in the mining schedule, when ore passes
are available in the pit, the crusher should be
moved back to the pit. All ore storage sites will be limed.
5. Pit Water The majority of pit water will occur as a result of
the elements and "run off" from hi gher ground. It
will also be drained into the pit via the decline

After f ive years of operation, and a good cash flow

After five years of operation, and a good cash flow
has been generated, it is envisaged that an under
ground conveyor system could be used for all ore transportation.
The decline ramp would be approximately 4500-
feet long at a -15% gradient, and would start at a
portal adjacent to the mill. A series of ore passes
and fingers will be driven from the ramp, in ore, to
the pit bench. A series of two conveyors will be
hung from the back and feeders installed in the ore
pass raise above the belts. Ventillation intake
and exhaust raises will be driven to surface and
fans and heaters installed. The exhaust raise will be outfitted and used as an escapeway.
(Refer to Figures 3 and 4).
This system will allow the portable crusher to
crush near an ore pass grizzly and use its stacking
belt to feed directly to the ore pass. Scooptrams
will be required to supply the crusher. The ore
could be crushed to -4" or less, that would r'educe
wear on the belt and reduce crushing time and costs in the mill.

On completion of mining, certain work will be required
in order to conform to present mining and environmental regulations, and ultimately to return the area to its

If however, the mine produces for the mining life

Based on the mlnlng plan detailed in the previous
section, ore tons, grade and waste tonnages for each mining
zone are listed below:
(in 1000s) Stripping Ratio Zone Tons Grade vJaste: Ore
Initial Open Pit 2,769 2.74 0.39: 1
Main Open Pit 12,907 2.34 1 . 14: 1
McGuire Lake Pit 3,333 2.99 To be assessed after ~1innow Lake Pit 6,325 2.36 lakes drained and Drilled.
Assume 1:1 ratio for study
Below Main Pit 4,118 2.08 U/G Mining
TOTAL 29,452 2.42
As previously stated in this report, specific pre
production work is required before mining ore can commence.
However, for the purpose of drawing up the following time
frame production schedule; it is assumed this work has
been completed, and Year 1 starts when milling commences.
It is pointed out, that the mining rates stated can be
increased, as production is governed by the mill capacity
that in turn is geared to sales volume.

c. OPERATING COSTS
Operating costs have been calculated for a mining period
of thirty four years, the time period assumed for this
analysis. Underground mining commences after this time and
costs have not been requested for this study.
Waste
The cost of handling waste has a large cost impact
due to the magnitude of the tonnage involved. A waste
disposal analysis was made, and it is possible to reduce
the waste handling costs dramatically, over the thirty
four year period. The costs of breaking and hauling waste
for the construction of tailings dams in the treatment system is a legitimate charge to Capital Expense.
Table 9 shows the disposal locations for waste.

# 3 Scenario (Tons in 1000s)($ in 1000s CAN.)
Covers years 6-34 inclusive and the only difference
between # 2 and # 3 Scenario is the ore handling. In this
scenario, the ore will be broken and crushed in the pit,
and dumped through grizzlies, into ore passes and transported
to the mill by a series of two conveyor belts to the mill.
The waste can be handled the same way, but for this study it
will be assumed it is done the conventional way, as in

D. PERMANENT DEVELOPMENT COSTS
A permanent development cost will be entailed for
the ramp decline required for use initially as conveyor
gangways and eventually for use during the underground
phase of mining. All development will be in waste or low
grade ore, and will be done by a contractor.
An area contractor was approached and asked if they
would consider supplying a tentative price schedule for
the underground work at the "ea 1 Graphite" property. It
was emphasized that these costs were for a "Feasibility
Study" only, and in no way was the request to be construed
as a tender to perform work or a guarantee that they would
be awarded the contract if the property was to be developed.
These conditions were accepted and their cooperation was
excellent.
A meeting was held in the Lively, Ontario, field
office of Cal Graphite Corporation and the mining and
development method was explained.
General parameters given to assist in developing costs ~vere:
Work to be performed on a 3-shift/day, 6 day/
week basis, with the contractor supplying all
equipment and materials to complete his specified work.
ii All technical support services, surveying,
geology and engineering control would be supplied
by Cal Graph ite.
iii Cal Graphite would supply electric power and water.
iv The contractor would supply all piping, ventilation
tubing, rock bolts, rebars, screen and any other ground
conditioning materia7.

4. CAPITAL COST
The capital costs are listed on the following Table in the year they occur.
Capital Costs are in 1986 dollars, and a residual value has not been assessed for milling or mining equipment due to the large production tonnages and length of time involved.
Abandonment costs are estimated for re-generating the open pit areas only, as underground mining will continue after year thirty four, the time period under discussion.

4. Power and Reagent Consumption
Average power consumption in the rod mill was 2.4 kWh/tor.I • Approximate ly
150 g/t kerosene was added to the rod mill and rougher flotation as ;he primary
graphite collector. Approximately 200 g/t NaOH and 500 g/t Na 8ili Lte were
added to the scavenger circuit to d~sperse and depress the gangue c lstituents
in the flotation recovery of -100 IIlesh graphite.

NATURAL GRAPHITE
Graphite is a natural form of carbon. Natural graphite is a lustreous, black carbon mineral, crystallized in the hexagonal system with rhombohedral symmetry. Flake graphitp. is opaque, flexible and sectHe. and exhibit~ perfect basal cleavage. Natural graphite is unctuous and is relatively soft with a hardness of 1 to 2 on Mohs' scaI€'. It has a black colour and a biack streak on glazed porcelain. Its specific gravity :is 2.266 g/cm3. Graphit~ iR an excellent conductor of heat and electriCity; and it has a high melting temperature of 3 OOO·C, It is extremely resistant to acid, chemically inert Ilnd highly refractory.
Natural gnphite \is widely distributed throughout the world ',and is of common occurrence in metamorphic rocks produced by regional or contact metamorphism. Amorphous graphite is a microcrystalline graphite fonned by crystallization of the, carbon from organic sediments such as coal. The graphite occurs as distorted seams of minute microcrystalline particles in termixed wit h ungraphitized materials. The graphite content may vary from 15 per cent to 98 per cent depending on the degree of metamorphism and the original carbon content in the sediments. Crystalline lump, or vein graphite, occurs in the form of massive vein or circular accumul;:ttion formed probably from hydrothermal origin. The graphite occurs along the contacts of intrusive rockB with limestones. Such occurrences appear in foliated or columnar forms. Crystalline flake graphite is found disseminated in m~tamorphosed siliceous or calcareous sediments such as marble. gneisg and schist.

USES AND SPECIFICATIONS
T h e uses of natural graphite depend on its physical and chemical properties. The s t r eng th of graphi te increases an i ts temperature rises. I t has a high thermal conductivity and a low absorptivn coefficient for x-rays and electrons. Flake graphite enhances anisotropy in bodies where forming processes, such as extruslon and pressing. align the flakes. It res is ts oxidation better than granular graphite.
Flake graphite is used in the manu- facture of crucible for the steel, nonferrous and precious melals industr ies . It is pre- f e r red to microcrystalline graphi te because it bu rns more slowly, has a high attrition resistance and imparts s t ructural s t rength

North America will remain largely dependent on foreign sources for graphite. No shortage of gr.phlte Is foreseen as world resources of natural graphite appear unllmited. However. the availability of the low-cost. high-grade graphite could be affected by the policies of foreign govern-
ments in supplying cI)untrles. Should this happen development of alternative sources nf high-grade graphite will likely occur In order to seCUre indURtry. especially in Japan and the United States which will sUI! have to rely on imports for coarse crystalline n"ke graphite.

Dear Sir: RE: Cal Graphite -Feasibility Study
As stated in our discussions, a feasibility study is be 19 done for Cal Graphite Corporation, relative to their property in Butt TWp., Ontario
The intention is to mine the ore body by open pit a dep 1 of 450 feet vertically below lake elevation. Initially, t ore will be broken, crushed to - 6" and hauled to the m Ll, an average distance of 3000 feet. The longer term plan calls for a decline ramp 12' X IS' to be driven a.,.proxi ltely 4500 feet, that will form the conveyor gallery. Inclin 1 ore passes will be driven and ore will be crushed to -6 dumped into the ore passes, and conveyed over the belt the mill.
It would be appreciated if you could submit unit prices :or the work described on the attached list. Replies will: kept confidential.
A tentative production schedule is as follows:
TONS/DAY
ORE WASTE
Year 1 ~OOO 300
2 1500 450
3 2500 1200
4 3000 3000
The decline ramp will be started during this period.
Thank you for your assistance.
Yours truly,
