1.0 INTRODUCTION
Facilitated by the cutting of a 3.2 line kilometer grid a ground magnetic survey was
conducted on the West Langmuir group of claims on behalf of Black Pearl Minerals Inc.
from August 11-12, 1998. The purpose of the program was to map the bedrock geology
and identify the potential for economic base metal and\or gold mineralization of the
property. The program consisted of clearing out the claim boundaries, cutting and
surveying an East-West Baseline (BL 12 N), the cutting of 9 100 m spaced crosslines
(L16W to L24W), and running a magnetometer over the entire cut grid.
2.0 PROPERTY LOCATION AND ACCESS
The West Langmuir property is located in the south west quarter of Langmuir Township
near the boundary between Langmuir and Fallon Townships, in the district of Cochrane,
Porcupine Mining Division of Ontario, Canada. The geograghical coordinates are Latitude
48 17' N and Longitude 81 03' W. (Fig 1).
The property is located 30 km southeast of the City of Timmins. It is accessible by an all
weather gravel road 31 km south of South Porcupine to within 14 km west of the property.
A seasonal tractor road passes through the north west part of the property.
The property consists of 2 unpatented mining claims held by Mr. D. Meunier of South
Porcupine. The property is currently under option to Black Pearl Minerals Inc. The claims
are listed below and are shown on the accompanying Property Map (fig 2).

3.0 PREVIOUS WORK
Early 1900 - Porcupine Miracle sank a shaft to 200 feet. This is located a few meters
north of claim P. 825716.
1983- Mercier Exploration Limited conducted radiometric, EM, ground magnetic
and geological surveys over a claim group that spanned the Langmuir/
Fallon Township boundary. The West Langmuir Property was part of this
group. Significant gold, silver and base metal assays were obtained from
the mafic volcanics located 1.5 km east of the property.
1984 - 86 Lac Minerals conducted geological, ground magnetic and EM surveys and
diamond drilling over a claim block east of the West Langmuir Property.
Anomalous base metal results were obtained from diamond drilling the mafic
volcanics.
1992 - Trinity Exploration conducted line cutting, ground magnetic and VLF surveys
and geological mapping on the Porcupine - Miracle Property adjacent to the
north section of the property. Sampling of the old muck piles in the vicinity
of the shaft returned gold assays up to 495 ppb.

4.0 GEOLOGY
4.1 REGIONAL GEOLOGY
The rocks underlying the area are part of the Abitibi Greenstone Belt which is part of the
Abitibi Sub-Province of the Superior Province of the Canadian Shield. The part of the
Abitibi Greenstone Belt that underlies Langmuir Township is composed of volcanic,
sedimentary and intrusive rocks that strike northeast in the northwest part of the township
and almost east-west in the southern part of the township. This is illustrated in figures 3 S
5. The volcanic, sedimentary and mafic to ultramafic intrusive rocks are located between
three plutons. The most westerly of the plutons is a small trondhjemite stock which
extends from Eldorado Township eastward into the west-central portion of Langmuir
Township.
The Fallon Stock is classed as a monzonite (Pyke 1981). It is predominantly located to the
south of the property in Fallon Township and does extend north into Langmuir Township.
The Blackstock Granodiorite ( Pyke 1970) extends west from Blackstock Township into the
extreme east-central part of Langmuir Township.
The volcanic, sedimentary and mafic to ultramafic intrusive rocks are draped around these
plutons and the variable strike and dip of these rocks are as a result of this. These rocks
are grouped into three assemblages (Jackson and Fyon 1991). The assemblages are
arrayed from northwest to southeast with the oldest rocks to the northwest and are
described below.
The Deloro Assemblage consists of pillowed, amygdaloidal, feldspar phyric calc-alkaline
basalt and andesite (Pyke 1982). The volcanics have been intruded by mafic to ultramafic
intrusive rocks which have been classified as gabbro and serpentinized dunite by Pyke
-5- POLK GEOLOGICAL SERVICES
1970. The contact between the Deloro Assemblage and the overlying Eldorado
Assemblage is thought to be stratigraphic (Jackson and Fyon 1991).
The Eldorado Assemblage consists of intermediate to felsic volcanic rocks, iron formation,
fine clastic sediments and ultramafic flows and intrusives. The contact with the overlying
Bowman Assemblage is conformable (Jackson and Fyon 1991). The volcanic rocks are
primarily rhyolitic to dacitic tuffs. Sedimentary rocks are oxide and sulphide facies iron
formation, chert, fine-grained sandstone and shale (Pyke 1982). Ultramafic rocks are
classed as peridotitic komatiites. The ultramafic intrusive rocks are described by Pyke
1982 as serpentinized dunite.
The Bowman Assemblage is a south facing series of peridotitic and basaltic komatiitic
flows interlayered with magnesium rich basalts.
Late diabase dikes occur throughout the area and are grouped into three types. The north
striking dikes are part of the Early Precambrian Matachewan swarm. Pyke 1982 has
shown the north-east trending dikes are divided into the Middle Precambrian Abitibi and
Late Precambrian Keewanawan swarms.
The area is covered by a blanket of Pleistocene glacial and post glacial sand, gravel and
clay.
Structure
The major structural feature in the area is the Montreal River Fault which cuts the township
in half in a northwest-southeast direction. It has a vertical dip and movement along the
fault is left handed. There are several other parallel to sub-parallel faults cutting across the
area. One northeast trending fault is known to cut across the area in the vicinity of the
Forks River ( Figure 5).

4.2 GEOLOGY OF THE PROPERTY
Outcrops on the property are generally restricted to the flanks and top of a topographic
high located on claim P. 825716. Four rock types were identified on the property and they
are described in the following section. The distribution of the outcrops is shown on the
West Langmuir Geological Map.
The property is underlain predominantly by metamorphosed mafic volcanics and ultramafic
peridotite flows. A 20-30 meter wide, North northwest trending diabase dike traverses the
property in the central portion of claim P.825716. An occurrence of porphyritic intrusive
was unearthed near the top of the claim group at the top of line 21 W.
Overburden
The overburden consists of a variable mantle of lacustrine silt and clay. The property is
well drained with a fairly mature forest cover of white and black spruce mixed with poplar.
The western end of the property is low-lying with local cedar and alder swamp.
Peridotitic Komatiite
The peridotitic komatiitic rocks (Bowman Assemblage, Jackson and Fyon 1991) are of a
flow nature. Good examples of this are found at the South end of L 18 W. There, a large
outcrop displays excellent spinifex and polysuturing textures. The orientation of these
flows is apparently 030, which is more northerly than other rocks seen on the property.
This may be explained by this outcrops proximity to the North Northwest diabase dike.
Most of the flows tested were weakly carbonitized.
.7. POLK GEOLOGICAL SERVICES
Mafic volcanics
The mafic volcanics observed on the property are quite similar in composition to the
ultramafic volcanics. They are set apart only by a finer grain size and an increase in
hardness. They tend to be very fine grained and dark grey green in colour and weather
to a dull brown as opposed to the rusty weathering of the ultramafic volcanics. Property
scale banding of the mafic and ultramafic volcanic units may represent cyclical
differentiation of the flows over time during deposition.
Diabase Dike
A large North Northwest trending dike (^20 M wide) cuts the property in the central portions
of claim P.825716. The dike is generally coarse grained but, some finer grained phases
were observed. The dike is generally magnetic but, so are the ultramafic flows.
Porphyritic intrusive
At the intersection of the Base Line (12 N) and Line 18 W , a small outcrop on the North
West corner of a sub crop related topography high was shown to host a significant volume
of porphyritic intrusive material. Within the outcrop is also some mafic volcanic material
contacting the porphyry in 2 ways: 1) fault contact along north trending fault or shear zone
and 2) irregular east west contact. It is apparant that the mafic volcanics are a raft caught
up in the felsic intrusive. The contacts showed no more than mineralization than did the
porphyry in general but, sampling was done with the possibility in mind.
This porphyry is pink in colour with some degree of hematization present. The porphyritic
phase is generally feldspar and the blasts are generally between 1 and 4 mm in dimension.

5.0 LINECUTTING
A linecutting program was carried out between July 27-31 1998 by Brian K. Polk, Jean
LaForest and Jim Perello all of whom reside in Timmins, Ontario. The grid consists of one
baseline (BL 12 N), 4 feet wide, with 9 cross lines (L16W to L24W), 3 feet wide, at 100
meter spacings for a total of 3200 meters. Pickets with labeled aluminum tags were
stationed every 25 meters and the grid was tight chained from the baseline with the
Baseline/ L24W intersection as an origin. The grid is shown in Map 1 (Magnetometer plan
with grid).
5.1 GPS SURVEY
In order to establish accurate survey control for this property and other Black Pearl
Minerals property in the area, Differential Positioning GPS was used to establish sub-
centimeter UTM coordinates for the end points of the base line. The coordinates are as
follows:

6.0 MAGNETOMETER SURVEY
The magnetometer survey was conducted by Kent Robinson of Timmins, Ontario between
August 11-12 1998. The ground magnetic survey was carried out using a (Gem Systems)
GSM-8 Proton Precession magnetometer. A base station was established at Hussey
Geophysics Inc. at 714 Mclean Drive, Timmins, Ontario using an identical continuous-
recording Gem Systems magnetometer to reduce diurnal variations. The magnetic datum
used in this case was 58,000 gammas. Readings were taken at 25 meter intervals along
the 100 meter spaced lines for a total of 3200 meters, with local fill-in readings in areas of
high magnetic intensity (300 meters). Refer to Appendix A for instrument operations and
specifications.
7.0 SURVEY RESULTS
The magnetometer survey was successful in outlining the basic geology of the property.
The contoured magnetometer map (MAP 1) shows the rocks trend Northeast to East
north-east across the property and are divisible into somewhat discrete magnetic units.
-10- POLK GEOLOGICAL SERVICES
Geologically the property is apparently underlain by 3 series of volcanic rocks, each with
ultramafics at the base differentiating into mafic flows to the north. The magnetometer
readings in the Southeast portions of the property are definitely substantiated by the
geology observed at those stations (i.e. high mag over ultramafics and diabase). The
diabase dike is fairly obvious but, because the surrounding rocks are generally magnetic
as well, the dike signature is locally obscured. Perhaps the most interesting feature is
found near the BL around L20 W then trending SW to terminate at 10+50 N at
approximately L21W. This magnetometer low feature represents the lowest magnetic
signature on the property and trends onto the historic Porcupine-Miracle mining property.
On this property, 2 shafts, one of which goes 200 feet down, were driven within a
mineralized felsic intrusive body (porphyry). The magnetometer survey indicates that this
porphyry does underlie some, if not a significant amount, of Black Pearl's property.
-11- POLK GEOLOGICAL SERVICES
8.0 CONCLUSIONS AND RECOMMENDATIONS
The magnetometer survey was successful in providing a good general geology for the
property in question. The survey agrees well with observed geology at a few locations on
the property and indicate the presence of a historically mined and mineralized porphyry
body on the property.
Recommendations for future work include geological mapping with some hand or
mechanical stripping around the porphyry occurrence outlined by prospecting and indicated
by the magnetometer survey.

- 4 -1.2 EARTH'S MAGNETIC FIELD
Figure l shows nominal distribution of Earth's magnetic field in kilogammas, with dotted lines separating equatorial and polar re gions. In polar regions an inclination of magnetic field vector is closer to vertical, while in equatorial regions it is nominally horizontal. To obtain the best precession signal and superior qua lity of operation, the sensor must be aligned accordingly. Orien tation line at the side of the sensor should be oriented vertically in polar regions and horizontally in equatorial regions. Although maximum signals are achieved by aligning the sensor orientation line close to the actual direction of the magnetic field, it is ge- ncraly not necessary to go beyond horizontal/vertical orientation mentioned above.
Range position on a front panel of the instrument should initially be selected closest to a nominal value of magnetic field shown for particular region in fig.l. As local distributions of magnetic field could be considerably altered, a proper range position should be determined by first valid reading of the magnetometer (first two digits of the display show a real magnetic field value for the place of measurement). During a survey, the field value may change beyond initially used range and the Range switch position should be adju sted accordingly, although the GSH-B will generally work correctly on several adjacent ranges.
Local ferromagnetic objects like screws, nuts, pocket knives, nickel coins, wristwatches, tools etc. may impair the quality of measurement by modifying the value of local magnetic field being measured or in drastic cases by even destroying the proton precession signal due to excessive gradients. For best results ferromagnetic objects should be kept away from the sensor. NiCd batteries, al though slightly magnetic, do not produce visible effect on measu rements if the sensor is installed on the staff and kept at arms length away from the operator and the console. For back-pack in stallation of the sensor a nonmagnetic set of batteries is recom mended .

3.1 INSTRUMENT DESCRIPTION
Major parts of the magnetometer are shown in fig. 3.1
(1) SENSOR, optimized for high sensitivity and gradient tolerance
(2) FILLING PLUG, to fill the sensor with proton rich liquid (kerosene or similar)
(3) CABLE CONNECTOR
(4) CABLE
(5) ORIENTATION LINE
(6) STAFF
(7) SHOULDER STRAP
(8) SENSOR CABLE CONNBCILR/ON-OFF SWITCH
(9) RANGE SWITCH
(10) DISPIAV WINDOW
ill) PUSHBUTTON, to initiate a desired mode of operation
(12) CHARGER/INTERFACE CONNECTOR for digital/analog output and external trigger, charger or external batteries
3.2 SET-UP AND OPERATING PROCEDURES
GSM-B is shipped with fully charged internal batteries, ready for field opera tion. To set-Lip the instrument, the sensor should be attached to the staff with correct direction of the orientation line and the staff extended. Connecting the cable to the front panel sets the instnnent in standby state. The display may or may not light at this point.The Range switch should now be switched to position closest to the local total iragnetic field intensity as shown in fig. 1.1Operation of the GSM-8 is internally nonltored and incorrect readings (due to external interference, excessive gradient or internal breakdown) are marked by two decimal points appearing after third and fourth digit of the display. Readings marked by decimal points should be disregarded.For best results the Range switch should always be set to the position closest to the first two digits of the displayed value of magnetic field. During surveys this may need occasional correction.
There are three modes of operation Of GSM-B l
b)
c)
a) Short depressinq of the pushbutton will initiate a SINGLE READING. Initiation is marked by a colon after second digit of the display. The colon stays liqhted only durinq polarization interval. The value of measured magnetic field appears on the display in gammas after about 1.85 sec. and stays displayed until the next reading isl taken or the instrument switched off. Incorrect readings are markej by decimal points, which stay displayed with the reading.
In SELFTEST MODE the pushbutton is pressed permanently. This mode consists of one normal reading of magnetic field, display test (displaying 88888) and battery test. Battery voltage is shown in ij although accurate only about 5*. This cycle is being repeated as long as the pushbutton is depressed.
In CYCLING MODE the pushbutton is depressed during polarizing infc until a new reading appears on the display and then released. Aft' display and battery tests, the instrument will start cycling auto matically at the rate of one reading in about 1.85 sec. A short depression of the pushbutton at any time will stop cyclina (after completing the cycle under way).Cycling mode is very convenient for base station and vehicle born'? operations or Cor a quick check-up of instruments consistency. . However, as it results in a large number of readings and relatively fast draining of the batteries, the cycling mode can optionally be disabled to prevent accidental initiations in a field.
Before starting a survey the batteries and the display should be checkej Battery voltage for fully charaed batteries must be above 12,500 on tht display. No survey should be started with battery voltaae being below 11,000 mV as shown on the display.
3.3 EXTERNAL BATTERIES
4. MUNftHftTCE AND REPAIR
- 9 -
GSM-8 is generaly^Rintenance free except for occasional cleaning and visual inspectioitfjtfi*chard.cal conditions of the cable, sensor and display window. Due tpjiosnblUties of gathering magnetic dust, the sensor, cable and staff should be periodig&ly washed with soap or detergent and water. Beycnd that a normal "carmen oonfe care" should ensure lasting use in rough field conditions.
When not uaeZr for longer periods the instrument should be returned to the car rying case, with sensor disconnected from the console.* i'Batteries should be kept charged when storing,the instrument. As NiCd batte ries have a memory , cycles of partial charging and discharging may result in reduced capacity. This can be cured by few cycles^ of full discharging and charging. Relatively fast discharge can be achieved by'setting^the instrument into cycling. Normal charging will take 14-16hr, while'fast charging using special charger (available from the manufacturer) can be'completed, within 3-4hr Spare NiCd batteries are readily available fron the manufacturer.'^.
'*- Ir ttt - ,.frSensor cable might occasionaly get damaged or broken iff heavy use. Vten repai ring be careful to connect centre wire to positivanerninal of the sensor and. pin A of input connector. All other wires and a shield are connected to negative terminal of the sensor and pin B of input connector. Pins C and D of the input connector must be shorted; the short acts aa J the main switch.
Use of improper external battery or short circuit in the sensor-cable assembly may blow a fuse (instrument appears completely dead). Spare fuses are found on the smaller of the two boards. The fuse must be soldered in, but it is highly reccnmended that the cause of malfunction be previously determined and removed. If sensor short is suspected, an ohm-meter can be used to measure a resistance between pins A and D of the input connector. It must be within 15-20 Chm. '"j;.-,** T^- - * .
While internal batteries satisfy any requirements for normal hand held (portable) operation even in cold weather, use of external batteries nu™, be necessary for base station or vehicle borne operation where automatic cycling is needed. For this purpose any 12V car battery will be satis factory, although lightweight external battery packages with sufficient^ capacity for 6-8hr of cycling operation may be ordered from the manufacl urer. \ Leads of the car battery can be connected directly to pins D (positive) and E (negative) of the Charger/Interface connector at the side of the console. Use of higher voltage batteries (up to I8v) requires that in ternal NiCd batteries be disconnected by opening an internal two pin , connector. Alternatively the batteries can be removed from the consolo by removina the instrument out of the case and then removing two screws at the range switch side of the larger PC board, pivoting the board for 90 degrees and undoing four screws holding the battery pack. Use of batteries of more than Ifiv may damaqe the instrument.External battery packs for disposable C or D size batteries, special . Alcaline or Mercury flat pack batteries are available from manufacture*!
