5. SURVEY METHODS AND FIELD PROCEDURES

5.1 Magnetic

The magnetic method consists of measuring the magnetic field of the earth as influenced by rock formations having different magnetic properties and configurations. The measured field is the vector sum of primary, induced and remnant magnetic effects. Thus, there are three factors, excluding geometric factors which determine the magnetic field. These are the strength of the earth's magnetic field, the magnetic susceptibilities of the rocks present and their remnant magnetism.

The earth's magnetic field is similar in form to that of a bar magnet. The flux lines of the geomagnetic field are vertical at the north and south magnetic poles where the strength is approximately 60,000 nT (or gammas). In the equatorial region, the field is horizontal and its strength is approximately 30,000 nT. The primary geomagnetic field is, for the purposes of normal mineral exploration surveys, constant in space and time. Magnetic field measurements may, however, vary considerably due to short term external magnetic influences. The magnitude of these variations is unpredictable. In the case of sudden magnetic storms, it may reach several hundred nT over a few minutes. It may be necessary therefore, to take continuous readings of the geomagnetic field with a base station magnetometer while the magnetic survey is done.

The intensity of magnetization induced in rocks by the geomagnetic field P is given by:

I r kH

where:

I is the intensity of magnetisationk is the volume magnetic susceptibilityH is the magnetic field field intensity

The susceptibilities of rocks are determined primarily by their magnetite content since it is strongly magnetic and widely distributed. The remnant magnetization of rocks depends both on their composition and their previous history. Whereas the induced magnetization is nearly always parallel to the direction of the geomagnetic field, the natural remnant magnetization may bear no relation to the present direction and intensity of the earth's field. The remnant magnetization is related to the direction of the earth's field at the time the rocks were last magnetized. Interpretation of most magnetometer surveys is normally done by assuming no reminant magnetic component.

Since the distribution of magnetic minerals (magnetite, pyrrhotite) will, in general, vary with different rock types, the magnetic method is often used to aid in geologic mapping. The magnetic survey is of particular importance because it may map areas of structural complexity, carbonatization, and silicification.

5.2 IP/Resistivity

5.2.1 Survey Method

The phenomenon of the IP effect, which in the time domain can be likened to the voltage relaxation effect of a discharging capacitor, is caused by electrical polarization at the rock or soil interstitial fluid boundary with metallic or clay particles lying within pore spaces. The polarization occurs when a voltage is applied across these boundaries. It can be measured quantitatively by applying a time varying sinusoidal wave (as in the frequency domain measurement) or alternately by an interrupted square wave (as in the time domain measurement).

In the time domain the IP effect is manifested by an exponential type increase or decrease in voltage with time. The frequency domain measures either the difference in voltage as a function of frequency (maintaining constant current) or the real and quadrature components of the voltage compared to the transmitted current.

Both methods measure essentially the same phenomenon and theoretically the response of one can be translated to the other domain by Fourier analysis. The two methods are qualitatively comparable if only a change in relative response amplitude is required, i.e. an anomaly in the time domain will have a similar anomaly in the frequency domain provided the noise levels and resolution of the measuring devices are the same.

The direct current apparent resistivity is a measure of the bulk electrical resistivity of the subsurface. Electricity flows in the ground primarily through the groundwater present in rocks either lying within fractures or pore spaces or both. Silicates which form the bulk of the rock forming minerals are very poor conductors of electricity. Minerals that are good conductors are the sulphide minerals, some oxides and graphite where the electrical flow is by electronic means rather than ionic.

The two methods of measuring the IP effect employ the same geometries of electrodes. The measurement is made by applying a current across the ground using the ground using two electrodes (current dipole). The potential field (voltage) and IP effect can then be mapped in an area around the current source using what is essentially a very sensitive voltmeter and a second electrode pair (potential dipole). The former parameter, when normalized for the amount of current flowing in the ground, reflects the bulk apparent electrical resistivity of the subsurface. The latter parameter, as previously mentioned, says something of the polarizability of the ground which is due to the content of metallic or clay minerals.

Disseminated mineralization does not occur in sufficient quantities to effect either the bulk polarizability or resistivity of the ground. The resistivity data is useful in mapping lithologic units and geologic structures such as faults, shear zones and pipes. For gold exploration it is particularly useful to delineate zones of silicification which is often associated with gold mineralization.

Historically the time domain IP response was simply a measure of the amplitude of the decay curve, usually integrated over a given period of time. Over the last decade, advances in technology have made it possible to measure the decay curve at a number of points, thus allowing the reconstruction of the shape of the curve. By measuring the complete decay curve in the time domain, the spectral characteristics of the IP response may be derived. The gradient IP array does not give an IP response suitable for an accurate spectral fit. In such cases spectral data is used as a check on data quality.

Recent studies have shown there is a relationship between the decay form and the texture or grain size of the polarizable minerals, i.e. the IP response is not only a function of the amount or type of the polarizable material. This could be important when it comes to ranking anomalies of equal amplitude or discriminating between economic and non-economic sources. The parameters that describe all the properties of the IP response are the spectral parameters m, c, and lau.

vxThe spectral data has proved useful in differentiating between fine-grained and coarse-grained sulphides or graphite. Gold is often found associated with sulphides that are fine grained. Experience has shown the M-IP parameter (derived m) is helpful in ranking anomalies in areas of high resistivity, where the apparent chargeability is increased systematicly. Also in areas of low conductivity, the parameter has proved advantageous in delineating lithology and determining which anomalies have sulphide sources.

As the source discrimination capability of the IP measurement (either time or frequency domain) remains somewhat unclear, we might recommend that in areas with geologic control, the IP decay forms be studied for significant and systematic differences. If such differences appear (at a particular receive time), such may be applied elsewhere in the same geologic environment. Our experience has shown time constants (tau) are important interpretation aids in areas of moderate to high resistivities which occur with pyrite in zones of silicification.

5.2.2 Field Procedures

The IP/resistivity survey on the G-Block property, Bisley Twp., employed the time domain method with a gradient array. The geometry of the gradient array is illustrated in the figure below.

The electrodes marked CI and C2 comprise the fixed current electrodes. Those marked by a PI and P2 are the potential electrodes and are moved between the current electrodes on a grid within the following constraints:

x/L remains less than 0.3d/L remains less than 0.3a/L remains less than 0.05

The line joining the two potential electrodes must remain parallel to the line joining the current electrodes. A separate and adjoining fixed current electrode setup is needed if gradient IP/resistivity measurments are to be read outside the current x/L or d/L constraints. The gradient array survey employed a 50m potential electrode separation and current electrode separation that was determined for each grid. The positions for the fixed current electrode separation are listed in Appendix B.

The waveform of the transmitted current is a two second on-off alternating square wave. The IPR-11 measures the voltage (primary voltage) across each potential dipole at an appropriate time after the current begins its on cycle, which approximates a D.C. measurement of voltage, in order to determine the apparent resistivity of the ground.

The equation for the apparent resistivity is given by

/^ r L'k/48 * V/I

where k = Z/Wl-V)/^2*^-!)}1 fa t {(HD)AZ2 t(H-D)8 )fcj

and Z r 2X/L and D r

For any array, the value of resistivity is a true value of subsurface resistivity only if the earth is homogeneous and isotropic. In nature, this is very seldom the case, and apparent resistivity is a qualitative result used to locate relative changes in subsurface resistivity only.

The IPR-11 will also measure the secondary or transient relaxation voltage during the two second off cycle of the current, which is a measure of the polarizability of the ground. Employing the two second cycle time, ten slices of the decay curve will be measured at semi-logarithmically spaced intervals starting at 45 milliseconds after current turn-off up to 1590 milliseconds after turn-off. The measured transient voltage when normalized for the width of the slice and the amplitude of the primary voltage yields a measure of the polarizability called chargeability in units of millivolts/ volt.

Chargeability (M) as measured by the IPR-11, is averaged over several periods of the transmitted waveform and normalized for:

1. the length of the integration interval;2. the steady state voltage and3. the number of pulses.

The spectral parameters M-IP, tau and "c" may be derived from the IPR-11 data with the Soft ][ software. Johnson (1984) summarizes the spectral parameters as follows:

M-IP: The chargeability (M-IP) is the relative residual voltage which would be seen immediately after shut-off of an infinitely long transmitted pulse (Seigel, 1959). M-IP is the numerically derived equivalent to Seigel's "m" or theoretical chargeability. It is related to the traditional chargeability, which is measured at discrete time intervals after the shut-off of a series of pulses of finite duration.

tau: The time constant (tau) and exponent (c) are those newly measurable physical properties which describe the shape of the decay curve in time domain or the phase spectrum in frequency domain. Por conventional IP targets, the time constant has been shown to range from approximately .01 seconds to greater than 100 seconds and is thought of as a measure of grain size. Pine grained mineralization loses charge quickly, coarse grained mineralization holds charge longer.

c: The exponent (c) has been shown to have a range of interest from 0.1 to 0.5 or greater and is diagnostic of the uniformity of the grain size (0.5 single grain size - 0.1 - many grain sizes).

The spectral fit for gradient array data does not give M-IP and tau values that can aid with the interpretation as mention above. As a result of this they were not plotted, but served as a data quality check. The spectral parameters, c, and the remaining slices of decay curve information (MO to M6, M8, and M9) were collected and monitoured to check the integrity of the data.

6. GEOPHYSICAL INSTRUMENTATION

JVX supplied the following geophysical instruments and accessories.

6.1 Magnetometer

One Scintrex IGS-2 system which included a Proton Precession Magnetometer, plus an MP-4 base station for automatic diurnal corrections.

The Scintrex IGS-2/MP-4 proton precession magnetometer system was used to take readings of the total magnetic field over the grid. An additional Scintrex IGS-2/MP-3 magnetometer is used as a base station magnetometer. Both units are microprocessor controlled and recorded readings with clock time on internal memory. The survey data from the field unit is corrected for ambient field changes at the end of every survey day by connecting field and base station magnetometers.

6.2 IP Receiver

The Scintrex IPR-11 time domain Microprocessor-based receiver was employed. This unit operates on a square wave primary voltage and samples the decay curve at ten time gates or slices. The instrument continuously averages primary voltages and chargeability until convergence takes place and the averaging process is stopped. Accepted data is stores internally on solid-state memory.

6.3 IP Transmitter

The survey employed the Scintrex TSQ-3/3.0 kw Time Domain Transmitter powered by,an 8hp motor generator. The TSQ-3 is designed for a selectable square wave output of 2, 4 or 8 seconds 'on' time. The in-field current output was accurately monitored with a digital multimeter placed in series to the current loop.

6.4 Data Processing System

a) An IBM-compatible portable microcomputer.b) Processing software including communications and plotting programs.c) An Epson dot matrix printer and tractor feed paper.d) Consumable items such as gridded paper, pens and floppy disks.

The instrumentation is described in greater detail in the specification sheets appended to this report.

7. DATA PROCESSING AND PRESENTATION

7.1 Magnetic

To allow for the computer processing of the data, the raw data stored internally in the data loggers of each survey instrumentation ( IGS-2/MP-4 for the mag units ) were transferred at the end of each survey day to floppy diskette by the in-field microcomputer and appropriate communications software.

An archived edited data file was created in the field from the raw data file by the operator removing repeat or unacceptable readings and correcting any errors such as station or line numbers. The concisely labelled and edited data were then output to a field printer as line profiles and contours.

In the JVX office the profiles, with posted values of the merged total field magnetic data, and contours of the total filed magnetic data were re-plotted in ink on paper at a scale of 1:2500 employing a Nicolet Zeta drum plotter and an IBM PC/AT. Final report quality prints (profiles and contours) of the data at scale 1:2500 drafted on mylar employing Geopak software and Acad are supplied.

7.2 IP/Resistivity Data Processing

The IP survey data were archived, processed and plotted by an Corona PC-400 microcomputer using an Epson PX-80 dot matrix printer. The system was configured to run the Scintrex Soft ][ software package, a suite of programs that was written specifically to interface with the IPR-11 IP receiver and to calculate the spectral parameters. At the conclusion of each day's data collection, data resident in the receiver's memory was transferred, via serial communication link, to the computer - thereby facilitating editing, processing and presentation operations. All data was archived on floppy disk. In the Toronto office data was ink-plotted as profiles, contours, and filtered contours on a Nicolet Zeta drum plotter interfaced to an IBM PC/XT microcomputer.

To allow for the computer processing of the IP data, the raw data stored internally in the IPR-11 was transferred at the end of a survey day to floppy diskette by the in-field microcomputer and the Soft ][ communications software. The raw data was filed on diskette in ASCII character format using an IBM compatible (MSDOS) microcomputer. Once the data was stored on diskette, a number of processing techniques were employed.

An archived edited binary format data file was created in the field from the raw data file by the operator removing repeat or unacceptable readings and correcting any header errors such as station or line numbers. The concisely labelled and edited data was then dumped to a printer under the heading Data Summary.

At the end of each survey day the spectral parameters M-IP, c, and tau were computed employing the Scintrex Soft ][ software package. This program compares the raw transient decay curve with a library of curves calculated from known parameters and by least squares fitting selects a best matching curve. A listing of the spectral parameters and a measure of fit with appropriate station and line labels (Spectral Analysis Summary) were then generated on a printer.

The M7 slice/apparent resistivity gradient array data was profiled and contoured in-field. The gradient array plotting y-position is taken as the mid-point of the two potential electrodes.

In the JVX office the profiles and contours of resistivity/M? were re-plotted in ink on paper at a scale of 1:2500 (arSOm) employing a Nicolet Zeta drum plotter and an IBM PC/AT. Final report quality profiles and contours of the data at scale 1:2500 drafted on mylar employing Geopak software and Acad are supplied.

The maps are presented in Appendix C.

VX _______________________8. DISCUSSION OP RESULTS AND RECOMMENDATIONS

8.1 Introduction

The Blake River Reconnaissance project on the H-Block Bisley Twp. grid is located in the Kirkland Lake area. The H-Block Bisley Twp. grid was surveyed to delineate ground magnetic features observed from an airborne survey. The lines were cut 100m apart with 50m line spacing detailing the two main airborne magnetic anomalies of interest. Gradient IP/resistivity was surveyed in conjugation with magnetics, to take advantage of low chargeability and associated low resistivity data that respond to the lithologic units and geologic structures such as faults, shear zones and pipes. The 1992 ground magnetic and gradient IP/Resistivity surveys further define the anomalies and prioritize them for drill targets.

Previous work by JVX in the Kirkland Lake area has shown that kimberlites have a circular magnetic high l resistivity low signature. Circular resistivity lows that do not correlate with magnetic highs are also considered for further consideration. Caution should be given to magnetic highs l resistivity lows associated with chargeability highs, as sulphides can be responsible for resistivity lows and magnetic highs. The chargeabilities greater than 5 mV/V are indicated on the compilation map as solid bars on the survey lines.

The major anomalies and prioritized target areas are based on magnetic highs, resistivity lows, and the association of the magnetic responses with the IP/resistivity data. These magnetic and resistivity anomalies are associated with interpreted cross structures CS-1, CS-2 and CS-3 striking NNW and NNE respectively. The detailed areas of investigation were determined from an airborne magnetic survey and the majority of the anomalies are within the detailed parts of H-Grid. The major anomalies are defined and labeled as M1/RL1, M2/RL2, M3, M4/RL3 and minor anomalies M5, M6, and M7. The ground survey further defines the magnetic anomalies with a parameter of magnetic highs Mla, Mlb,...M4a, M4b, etc. that are prioritized as recommended investigation targets based on their association, with interpreted cross structures, resistivity lows, inflections of resistivity high/low trends and magnetic trends (dykes). Chargeability highs associated with magnetic highs f resistivity lows can be the result of disseminated sulphides and chargeabilities greater than 5 mV/V are indicated on the compilation map as solid bars on the survey lines. The resistivity highs are also labeled RH1, RH2, and RH3 as well as topographic features and out-crop to aid with the geological mapping.

The relationship of magnetic highs with faults, dykes, and other cross structures may be favorable for kimberlites. There is evidence of other cross structures and linear trends that could be better recognized with east and west extension of the grid and more detailed geophysical and geological surveys.

The recommended target areas are based on magnetic highs in association with the IP/resistivity data. With any available geological/geochemical data, the included profiled maps should be used to further prioritize the exploration targets. The individual anomalies are discussed and prioritized with suggested drill targets in the following section.

8.2 Interpreted Magnetic and Resistivity Targets

Anomaly Ml/RLl ( 1050S-L1200S l 50E-200E )

Ml is a medium/strong magnetic high consisting of two strong magnetic highs Mla and Mlb associated with resistivity low RL1. Kimberlites are believed to be magnetic highs f resistivity lows in contrast with the surrounding host rock. As indicated on the compilation map ( plate H-5 ), Ml/RLl is bound between interpreted cross structures CS-2 and CS-3 striking NNE and NNW, with interpreted linear magnetic trend/dyke DI striking NNW through the intersection of the interpreted cross structures. Kimberlites may be favorable along magnetic linear trends intersected by cross structures. With the exception of a small one station chargeability high at L1100S/125E (possible noise) the relatively low chargeability ( < 5 mV/V ) over Ml/RLl suggests the resistivity is not affected by sulphides.

Most kimberlities have circular geophysical signatures. Ml/RLl appears circular, but, the south extent of the magnetic high / resistivity low anomaly Ml/RLl is undetermined due to the limited south extent of H-Grid. The west extent of RL1 is not accurately verified due to no IP/resistivity data recorded over, a beaver pond, on line L1100S from 25W to 100E. Two detailed lines at 1050S and 1150S as well as the south continuation of the grid is recommended to determine if the RL1 resistivity low extends as background or if RL1 is restricted to the dimensions of a near circular anomaly i.e. a kimberlite.

As indicated on the compilation map Ml/RLl consists of two strong linear magnetic anomalies labeled Mla and Mlb. Mla is part of the interpreted linear magnetic trend/dyke DI, striking NNW. Mlb is a strong magnetic anomaly on the SW side of Mla and centered within the resistivity low RL1. The magnetic anomaly Mlb has a short EW wavelength suggesting a shallow source, but Mla is part of Ml/RLl and therefore may be a magnetic high within the larger magnetic/resistivity feature. Mlb may be a kimberlite pipe intruded along the interpreted magnetic dyke Mla

TARGET T-la ( L1100S / 182.5E ) Medium Priority

Target T-1 a is a medium priority target within the strong magnetic high/resistivity low anomaly Mla/RLl. T-la is a strong magnetic high (121 nT) and it's position is interpreted to be independent of the ajacent magnetic dyke DI. The combination of a magnetic high/resistivity low adjacent to an interpreted magnetic dyke and approximately 150 m south of the CS-2, CS-3, intersection makes it favorable for kimberlites.

TARGET T-1 b ( L1200S / 100E ) Low Priority

Target T-1 b is a strong magnetic high (121 nT), low priority target within the medium/strong magnetic high / resistivity low anomaly Ml/RLl. T-lb is favourable for kimberlites due to it's close association to the interpreted magnetic dyke DI and interpreted cross structure CS-2. Mlb may be

circular around Tl-b but this cannot be confirmed without a detailed grid extention. Detailed south extension of the H-Grid can confirm the shape and dimensions of Ml b around target Tl-b and may raise the priority of T-lb.

Anomaly M2/RL2 ( Elliptical, L800S f L350S )

RL2 is an elliptically shaped resistivity low. RL2 is associated with intersecting NNS striking magnetic dyke DI, magnetic highs M2 and M3, and interpreted cross structure CS-1. The SW and SE of RL2 is bound by interpreted cross structures CS-2 and CS-3. There is geophysical evidence of other cross structures and linear trends that could be better recognized with EW continuation of detailed geophysical lines.

M2 is a medium/strong magnetic high within RL2 approximately 300 meters wide and 450 meter long, centered along 150E. Interpreted cross structures CS-1, CS-2 and CS-3 bound M2 at the NW, SE and SW respectively. M2 consists of two very strong magnetic anomalies labeled M2a, M2b as well as the interpreted magnetic dyke DI on the west side of M2.

M2a is a circular moderate ( 160 nT ) magnetic anomaly on the south side of M2 and is associated with the inflection of the resistivity low. M2a is a high priority target for follow up. ( Target T-2d )

M2b is a short strong magnetic anomaly with an associated inflection point resistivity low located near the intersection of structures CS-2 and CS-4. M2b is target T-2e.

Three other weak magnetic high targets are designated T2a, T2b and T2c. Targets T2a and T2b are small magnetic anomalies associated with M2 and the southwestern part of RL2. Target T2c has a sharp resistivity low associated with it therefore is classified as a high priority follow-up target. Targets T2a and T 2b are low to moderate priority targets.

Targets T2a, T2b, T2c, T2d and T2e do not have any significant chargeability response therefore there is not significant sulphides associated with it.

Magnetic Anomaly M3 (300S to 500S )

M3 consists of two strong magnetic anomalies M3a and M3b located in the western part of the grid. The magnetic anomalies M3a and M3b are 36 nT and 159 nT respectively and are associated with the resistivity high trend RH1. The interpreted cross structure CS-3 is responsible for the separating M3 into two anomalies. Two recommended target areas T-3a and T-3b are indicated on the compilation and discussed as follows.

TARGET T-3a ( L400S l 100W ) Low to Medium Priority

Target T-3a is a strong 159 nT magnetic high on the west inflection of resistivity low RL2. The magnetic response of M3a is recommended for followup becuase of its association with CS-3 and dike D-l. This relationship of a magnetic highs with cross structures and flanking resistivity lows may be favourable for kimberlites.

TARGET T-3b ( 450S f 75W ) Low-Medium Priority

Target T-3b is a strong 148 nT magnetic high on the west inflection of resistivity low RL2. The magnetic response is similar to T-3a therefore warrants follow-up.

Anomaly M4/RL3 ( Circular, L350S f LOS )

RL2 is a circular shaped resistivity low approximatly 200 meters in diameterr long, centered at 25W/ 250S. The north continuation of H-Grid would verify the north extent of the resistivity low. RL3 is associated with intersecting NNS striking magnetic dyke DI, magnetic highs M4a and M4b and interpreted cross structure CS-1. The SW and SE of RL2 is bound by interpreted cross structures CS-2 and CS-3. There is geophysical evidence of other cross structures and linear trends that could be better recognized with EW continuation of detailed geophysical lines.

Pour areas are targetted for follow-up.

TARGET T-4a ( L100S f 75E ) Medium Priority

Target T-4a is a strong 147 nT magnetic high on the east inflection of resistivity low RL3. The magnetic response of M4a is recommended for followup becuase of its association with CS-1 and dike D-l. This relationship of a magnetic highs with cross structures and flanking resistivity lows may be favourable for kimberlites. The target looks like a fold nose which could also be favourable for gold.

TARGET T-4b ( 200S /175E ) Low-Medium Priority

Target T-4b is a strong 131 nT magnetic high on the east inflection of resistivity low RL3. The magnetic response is similar to T-3a therefore warrants follow-up.

Target T-4c is a weak 99 nT magnetic high on the west inflection of resistivity low RL3. The magnetic anomaly appears to correlate directly with the resistivity low therefore the target is a high priority for follow-up.

TARGET T-4d ( 200S /175E ) Low-Medium Priority

Target T-4d is a strong 166 nT magnetic high on the east inflection of resistivity low RL3. The magnetic response occurs on the east flank of a resistivity low therefore warrants follow-up.

Anomaly 7c ( 1000S f SOB )

TARGET T-7

Magnetic anomaly 7 c is a one line moderate 136 nT magnetic response located northwest of resistivity low RL-1. The magnetic anomaly is associated with the creek and is adjacent to the dike which makes the anomaly worth following-up.

The other magnetic targets ( M5, M6, M7 ) should be reviewed. We have targetted magnetic anomalies with associated conductivity as this is the kimberlite model however all magnetic anomalies should be reviewed..

The chargeabilities are generally low with some higher chargeabilities located on RH-1. This area could be prospected for gold as well as any areas with chargeabilities over 7 Mv/V.

H-Grid, may be further followed up with additional geological/geochemical information. Pole dipole induced polarization f resistivity surveyed across the recommended targets would provide additional depth information and further locate the source.

9. SUMMARY AND CONCLUSIONS

During October to December 1992, Line-cutting, Magnetic and Gradient IP/Resistivity surveys were carried out by JVX Limited on behalf of Sudbury Contact Mines Ltd. c/o W.A. Hubacheck Consultants Ltd. on the Blake River Reconnaissance project, H-Block Property, Bisley Twp.; Kirkland Lake area, NE Ontario.

The recommended target areas are based on contoured magnetic highs in association with the IP/resistivity data. The highest priority targets are in the north and center part of the grid where large magnetic highs are intersected by interpreted cross structures and resistivity high l low trends. This relationship of magnetic highs/resistivity lows with faults, dykes, and other cross structures may be favorable for kimberlites. There is evidence of other cross structures and magnetic/resistivity target areas that warrant more detailed geophysicist surveys. Some caution should be given to the chargeability highs on lines 500S and SOW, as sulphides can be responsible for resistivity lows and magnetic highs. Detailed extension of the H-grid may help delineate the strike and length of cross structures and prioritize the anomalies with greater accuracy.

V X 18

The best targets with good associated resistivity lows are targets T-la, T-2d and T-4a. T-4c has a good resistivity low associated with it.

A line of pole dipole induced polarization / resistivity surveyed across the targets would also provide additional depth information and further locate the source. Clay areas which may cause resistivity lows could also have soundings performed on them to assure the resistivity low has depth extent. Other magnetic and apparent resistivity highs or lows (depending on the magnetic and resistivity contrast between the kimberlite and surrounding rock units) should be evaluated.

The geohysical data presented should be used in conjunction with available geological/geochemical data and the profiled geophysical data, to further prioritize the exploration targets.

The digital data from the H-Block surveys has been archived by JVX. A copy of all the data will be held by JVX on behalf of Sudbury Contact Mines Ltd. Sudbury Contact Mines Ltd. may at any time within this period request copies of the data on a time and materials basis.

If there are any questions with regard to the survey please do not hesitate to call the undersigned at JVX Limited.

IPR-11 Broadband Time Domain IP Receiver

The microprocessor-based IPR-11 is the heart of a highly efficient system for measuring, recording and processing spectral IP data. More features than any remotely similar instrument will help you enhance signal/noise, reduce errors and improve data interpretation. On top of all this, tests have shown that survey time may be cut in half, compared with the instrument you may now be using.

The IPR-11 Broadband Time Domain IP Receiver is principally used in electrical (EIP) and magnetic (MIP) induced polari zation surveys for disseminated base metal occurrences such as porphyry cop per in ac: H.-: ntrusives and lead-zinc

deposits in carbonate rocks. In addition. this receiver is used in geoelectrical sur veying for deep groundwater or geother mal resources For these latter targets, the induced polarization measurements may be as useful as the high accuracy resistivity results since it often happens that geological materials have IP contrasts when resistivity contrasts are absent A third application of the IPR-11 is in induced polarization research proiects such as the study of physical properties of rocks

Due to its integrated, microprocessor- based design, the IPR-11 provides a large amount of induced polarization transient curve shape information from a remark ably compact, reliable and flexible format Data from up to six potential dipoles can be measured simultaneously and

Function

The TSQ-3 is a multi-frequency, square wave transmitter suitable for induced polarization and resistivity measurements in either the time or frequency domain. The unit is powered by a separate motor- generator.

The favourable power/weight ratio and compact design of this system make it portable and highly versatile for use with a wide variety of electrode arrays. The medium range power rating is sufficient for use under most geophysical condi tions.

The TSQ-3 has been designed primarily for use with the Scintrex Time Domain and Frequency Domain Receivers, for combined induced polarization and resis tivity measurements, although it is compat ible with most standard time domain and frequency domain receivers. It is also compatible with the Scintrex Commutated DC Resistivity Receivers for resistivity surveying. The TSQ-3 may also be used as a very low frequency electromagnetic transmitter.

Basically the transmitter functions as follows. The motor turns the generator (alternator) which produces 800 Hz, three phase, 230 V AC. This energy is trans formed upwards according to a front panel voltage setting by a large transformer housed in the TSQ-3. The resulting AC is then rectified in a rectifier bridge. Commutator switches then control the DC voltage output according to the wave form and frequency selected. Excellent output current stability is ensured by a unique, highly efficient technique based on control of the phase angle of the three phase input power.

Scintrex has used low power con sumption microprocessors and high density memory chips to create the IGS Integrated Portable Geophysical System; instrumentation which will change the way you do ground geophysics.

Here are the main benefits which you will derive from the IGS family of in strumentation:

1. Depending on your choice of optional sensors you can make one, two or all of: magnetic, VLF and electromagnetic measurements. Thus, you may optimize the IGS system for different geophysical conditions and production requirements.

2. You will save time and money in the acquisition, processing and presen tation of ground geophysical survey data.

3. You will achieve an improvement in the quality of data through enhanced reading resolution, an increase in the number of different parameters measured and/or a higher density of observations. Further, errors which occur in manual transcription and calculation will be eliminated.

4. Your operator will appreciate the simplicity of operation achieved through automation.

5. Since add-on sensors are relatively less expensive, your investment in a range of IGS instrumentation may be much less than it would be with a number of different instruments, each dedicated to a different measurement.

The Scintrex IGS-2/MP-4/VLF-4/EM-4 permits one operator to efficiently measure magnetic. VLF and EM fields and to record data in computer compatible solid-state memory.
