1.0 Summary and Conclusions

During December, 1994, Royal Oak Mines Inc. hired M.C. Exploration Services Inc. to complete 12.0 km of Time Domain Induced Polarization (I.P.) and Total Field Proton Precession Magnetic (T.F.M.) survey work on their Semple-Hutt property located about 62 km south of Timmins, Ontario.

This work was successfill in outlining several areas which responded favourably to the I.P. survey, and work to determine the cause of these I.P. responses, consisting of drilling and/or trenching, is warranted.

2.0 Property Description, Location and Access

The Semple-Hutt property consists of 42 claim units (672 ha) located about 62 km south of Timmins (Figure 1). These claims are within Semple and Hutt townships, and are listed in Table l and shown in Figure 2. The property is owned by Royal Oak Mines Inc., P.O. Bag 2010, Timmins, Ontario, P4N 7X7.

3.0 Past Work and Geology

Work in the area of the property dates back to 1958, when Jonsmhh Mines Ltd. exposed what is now called the Decker Showing, a series of gold-bearing quartz veins within deformed mafic volcanics. This showing is about 500 m west of the area covered by this report (Rg. 2).

In 1962, geophysical and geological surveys and 5,095 feet of drilling was done by Hollinger, covering the Semple-Hutt property, with work ibcussing on a pyritic graphite horizon near the small lake in the southern part of the property. Work between 1972 to 1979 consisted mainly of geophysical surveys, and three holes were drilled by Essex Minerals in the area covered by and surrounding the current property.

The Decker Showing was re-worked in 1986-1988 by Pamorex Minerals, who did an IP. survey, mapping, sampling, as well as drilling seven holes totalling 2,442 feet. Assay results from drilling were disappointing, as they were not as extensive as those from surface sampling.

The property was covered by the Ontario Department of Mines in Map 2291 (1968). The map indicates the bedrock of the property to consist of a sequence of mafic, intermediate and felsic volcanics which have been folded into an east-plunging syncline, which has been subsequently cross-folded.

In 1992, the property was mapped by Royal Oak Mines Inc.

4.0 1994 Program

Between December 5 and 20,1994, MG. Exploration Services Inc. (P.O. Box 362, Porcupine, Ontario, PON ICO) completed 12.0 km of I.P. and magnetometer survey work, which was supervised by Richard Daigle.

The details of this work are in the Appendix, in a report written by R. Daigle, along with the pertinent maps and pseudo-sections.

5.0 Conclusions and Recommendations

As covered in the Geophysical Report (Appendix) several areas were outlined by the I.P. survey which require further work.

Possible near-surface sulphide mineralization occurs at Line O at (H-25S and Line O at S+75N, two areas that require testing by mechanical stripping.

The high chargeability on Line 2E at 7+OON requires drill testing.

Lower priority additional work includes drill testing of the mag and resistivity highs on Lines O to 3E north of the baseline.

Geophysical Agenda

Royal Oak Mines Inc. of Timmins, ON, completed 12 kilometers of Time Domain Induced Polarization Survey on the Semple-Hutt Property. M. C. Exploration Services Inc. ( MCX ) of Porcupine, ON, completed eight sections of IP survey using the Dipole Dipole Array reading n l to 6 with a Dipole Spacing "a" of 50 meters. Crews accessed the property travelling 70 km's south down the langmuir bush road out of Porcupine, ON. The fixed transmitter located along the Wicks road supplied power for all eight lines where crews started surveying line 300E then progressed westerly up to line 400W. LineslOOE, 0+00, 100W and 200W were problematical when crews attempted to achieve sufficient current for good penetration. Penetrating the high contact-resistance ( from 10 to 30 Kohm's ) involved using up to four grounding rods with a water-salt-copper sulfate solution to finaly lower the contact resistance for adequate penetration. Production was cut back by 50% until line 300W was reached. The IP survey statisics is included on the following page.

A Total Field Proton Precession Magnetic (TFM) Survey was then requested by Royal Oak and carried out by MCX on Dec. 19th, 1994. The EDA PPM-350 in conjunction with the EDA PPM-400 base station was used to cover the similar 12 km*s of NS grid lines. The detailed TFM survey read 970 stations and is leveled with a reference field of 57925nT's. The base station was located on tie line 1100N/ 150W. The TFM data range for the survey is from 57031 to 59969nT's with a mean of 58043nT's.

Equipment specifications and survey procedures are featured in the reports addendum.

The main objective of the geophysical program is to attempt to delineate a geological setting which may host auriferous quartz vein within intermediate to mafic metavolcanics. The showing developed by Pamourex in 1987-88 is assumed to strike near N70DegT. The showing is recognized with the following; minor conductivity where trenching revealed a zone of erratic quartz-calcite veining in silicified, carbonatized and sheared andesite with the quartz and adjacent wallrock well mineralized with disseminated to euthedral pyrite ( J. Hogan, 1988 Exploration Summary Report ). The mapped east plunging synclinal structure ( ODM map 2291 ) which in turn has been cross-folded onto itself will concern geophysical interpretations.

IP Section Evaluations

Line 300E is the first of eight lines read and has four separate anomalies. The first most southern anomaly is obscured ( off line ) and has a chargeability effect reaching 7 V/mV's with an apparent resistivity of 85 to 245 ohm's/ 50 meters. This characteristic implies sediments underlie the south segment of line 300E. The second IP anomaly from SON to 25ON with lower IP effects ( than the afore mentioned ), happens within a high apparent resistivity and is characteristic to possible ultramafic intrusive type rocks. The third IP anomaly at 700N with IP high and moderately low apparent resistivity happens along a postulated felsicXintermediate to mafic contact. The fourth IP anomaly is obscured to the north and implies probable sediment type rocks from SOON to 900N. The response over this limited segment correlates with mapped intermediate to mafic metavolcanics ( ODM map 2291 ) thus attributing the lower apparent resistivity to graphite content. Section 300E will be used as a guide to what may be expected on the remaining eight traverses.

The high apparent resistivity responses on the west portion of the grid are nearer to surface comparable to line 300E. This is conformable to the east plunging synclinal structure. The sections show anomalies dipping south from line 300W to line 200E, thus implying that the synclinal structure undertakes an upright tilt near line 100E. The IP high/ resistivity low running along the south limit of the survey implies a felsic/ intermediate to mafic contact runs near 200S across all the lines ( 4W to 3E ). A similar contact runs from line 400W/ 875N to line 0/875N, then takes a sinuous trend crossing line 100E/800N and then line O again at 375N and is traceable up to line 200W to then become confined. This occurs in conjunction with the mapped cross-fold seen on ODM map 2291. The broad high IP effects at the north limit of line 300E implies this line runs along strike. Another along strike response is seen on line 400W where a prominent resistivity high occurs. A moderately high resistivity response interrupting the broad high postulates an ultramafic/volcanic contact. The abiding ultramafic ( ODM map 2291 ) on line 400W/50N agrees with the IP survey and is then projected easterly across the grid. The classical IP effect seen on lines 300E and 200E with associated apparent resistivity response infers an intruding ultramafic unit with an upright tilt. Several intense high apparent resistivities due to near surface ( or outcrop ) effects obscure the deeper n levels, these problematical areas occur as follows; L400W/ 100S to SOON, L300W/ SON to 550N, L200W/ 100N S SOON to 700N, L100W/ 150N Si 550N to 700N and LO/ 125N fie GOON to 700N. Two of these surface effects have corresponding significant IP effects located on line O at 25S and 575N. Other similar near surface targets occur on lines 100W/ 25N 6. 525N and 200W/ 25N S 475N 6 700N. The near surface high IP effect on line 300W/ 75S happens with a lower apparent resistivity implying a target within intermediate to mafic metavolcanics.

Page 15: ROYAL OAK MINES INC SEMPLE-HUTT PROP 1994 ASSESSMENT …

Magnetic Evaluation

The magnetic results on Plan l are contoured at a 50 nanoTesla interval and show discontinuous trends. A broad high magnetic susceptibility reaching 1398 nT's intruding from the west ( line O from 300N to 600N ) up to line O occurs in conjunction with a high resistivity/ chargeability anomaly which infers a probable ultramafic unit. Two narrower high magnetic trends intruding from the west also happen on line 400W at 125S and SON, the northern high mag at SON correlates with mapped ultramafic unit seen on ODM map 2291. These highs then take a sinuous SE trend and become diffused. The most north weak twin highs from line 100E to line 300E associated with high resistivity and chargeability infer that a probable ultramafic unit follows this sinuous trend. The weak high magnetic anomaly seen on line O at 150S implies probable sulfide mineralization. The two mag lows seen on line O from 525N to 450N and SON to SOS perhaps reflect alteration, however are likely dipole effects from the flanking mag highs. The high mag reaching beyond 1900 nT's above background seen at the north limit of line 300W correlates with the mag high mapped by D. Londry ( 1987 Geophysical Report ). This high magnetic trend was then associated with variable concentrations of disseminated magnetite appearing to confirm a localized, tight fold in the area of the main zone.

Implications

The IP survey delineates several targets of significance where further testing is warranted. The near surface effects can perhaps be investigated by stripping. Two prominent key areas suggesting near surface sulfide mineralization are as follows; Line 0/25S and Line 0/575N. Both of these targets are traceable on line 100W and happen near surface. The IP high resistivity low on line 200E at 700N merits drill testing, however it can perhaps be correlated with the near surface anomaly seen on line O at 575N. Drill testing of the mag, IP, and resistivity highs trending across lines O to 300E north of the baseline would confirm the source of the intrusive unit.

Recommending more TEM survey be done on the target area in an EW direction at 100m intervals. This type survey can be done on compass orientated lines and tied into existing cut lines. The mag and IP targets seen at the north limit of the gridded area are problematical and warrant further investigation.

SURVEY PROCEDURE

MAGNETICS

Theory;

The magnetic method is based on measuring alteration in the

shape and magnitude of the earth's naturally occurring magnetic

field caused by changes in the magnetization of the rocks in the

earth.

These changes in magnetization are due mainly to the

presence of the magnetic minerals, of which the most common is

magnetite, and to a lesser extent ilmenite, pyrrhotite, and some

less common minerals.

Magnetic anomalies in the earth's field are caused by

changes in two types of magnetization: induced and remanent

(permanent). Induced magnetization is caused by the magnetic

field being altered and enhanced by increases in the magnetic

susceptibility of the rocks, which is a function of the

concentration of the magnetic minerals.

Remanent magnetism is independent of the earth's magnetic

field, and is the permanent magnetization of the magnetic

particles (magnetite, etc. ) in the rocks. This is created when

these particles orient themselves parallel to the ambient field

when cooling. This magnetization may not be in the same

direction as the present earth's field, due to changes in the

orientation of the rock or the field.

Page 18: ROYAL OAK MINES INC SEMPLE-HUTT PROP 1994 ASSESSMENT …

The most common method of measuring the total magnetic

field in ground exploration is with a proton precession

magnetometer. This device measures the effect of the magnetic

field on the magnetic dipole of hydrogen protons. This dipole

is caused by the "spin" of the proton, and in a magnetometer

these dipoles in a sample of hydrogen-rich fluid are oriented

parallel to a magnetic field applied by an electric coil

surrounding the sample. After this magnetic field is removed,

the dipoles begin to precess (wobble) around their orientation

under the influence of the ambient earth's magnetic field. The

frequency of this precession is proportional to the earth's

magnetic field intensity.

Field Method:

The magnetics data was collected with an EDA PPM 350 proton

procession magnetometer, which measures the absolute value of

the earth's magnetic field to an accuracy of */- l gammas. The

magnetometer was carried down the survey line by a single

operator, with the sensor mounted on an aluminum pole to remove

it from any surface geologic noise. Readings were taken at

12.5m intervals.

The readings were corrected for changes in the earth ' s

total field (diurnal drift) with an EDA PPM 400 base station

magnetometer, which recorded readings every 30 seconds as the*

survey was being conducted. The data from both magnetometers

was then dumped with a computer and base corrected values were

computed.

INDDCED POLARIZATION SURVEY

The Time Domain Method for Measuring IP

There are two basic systems or methods for the measurement of IP:

a) Frequency Domainb) Time Domain

In this'lecture we shall discuss the Time Domain method, its advantages and limitations.

The phenomena of induced polarization was reported in the literature as early as 1920 by Schlumberger. However, modern development of the method in the U.S. are generally dated to Bleil (1953). Khen a steady-state current into the earth is interrupted, it is observed that the voltage monitored at some point in the vicinity of the electrode generally does not immediately drop to zero. Instead, the voltage drops to some voltage V and thereafter decays with the time toward zero (see Figure 1).

Page 22: ROYAL OAK MINES INC SEMPLE-HUTT PROP 1994 ASSESSMENT …

The decay voltage or transient voltage indicates that the earth's resistivity is not simply resistive, but also has a reactive term too. The earth's resistivity is in general complex and might better be called an imped i vi ty. The term complex resistivity is more frequently being invoked to describe the total nature of the earth's resistivity. Modern time domain or transient techniques for measuring IP have developed from this very simple method of observing the IP response. A measure of the IP response, called CHARGEABILITY (M), is simply the amplitude of the secondary or decay voltage Vs (t) relative to the amplitude of the steady state voltage measured Vp while the current was on (see Figure 1).

The secondary voltage is usually much smaller then the primary voltage, so it is usual to express the secondary voltage in units of millivolts while retaining the units of volts for the primary voltage. Thus, the units of IP as measured using a pulse transient technique are often given a s mv/V. If the secondary voltage and the primary voltage are expressed in the same units, their ratio (i.e. Vs/Vp) is a dimensionJess fraction. Sometimes, therefore, the IP response (chargeability) will be expressed as a percent.

The definition of chargeability as suggested in Figure l indicates that it is a .function of time. Thus, there are an infinite number of possibilities for the definition of a single parameter which characterizes the measured chargeability or IP response. Much of the ongoing IP research today is centered around studying the total decay curve or, equivalently, the frequency spectra of the IP response, to determine additional information pertaining to the nature of the source of the IP response.

Modern time domain IP surveying instrumentation provides an efficient way of periodically repeating the experiment described in Figure 1. The time domain transmitter periodically pulses the current circuit. In addition, it com/nutates the polarity of the pulses. The transmitter waveform is illustrated in Figure 2. It is standard practice for the current ON time to be equal to the current OFF time. The ratio of the current ON time to the fundamental repetition period of the transmitter is often called the DUTY CYCLE and therefore when current on time equals the current off time the transmitter has a 50 percent duty cycle. An 8 sec repetition period (0.125Hz) and a 50 percent duty cycle is the most common IP transmitter waveform. However, there are some transmitters available for which both the duty cycle and the fundamental period can be varied.

DEFINITION OF NEWMONT IP PARAMETERS 'M 1 a 'L 1

FIGURE 2: Definition of the Neumt IP Parameters t" and -M*.

Standard Definitions for Chargeability (M)

Figure l suggests that the IP parameter, chargeability varies with time and so it does. However r for practical reasons the entire decay curve is generally not sampled. Instead, the secondary voltage is sampled one or more times at various interals.

Because the secondary voltage is received at extremely low levels in many prospecting situations, measurements of its amplitude at any given time is extremely susceptible to noise. Therefore, the secondary voltage is usually integrated for a period of time called a gate. Thus, if the noise has a zero mean, the integration will tend to cancel the noise. Figure 2 illustrates the "Newmonf gates. The Newmont M factor is a standard time domain IP parameter throughout North America. The gate delay (i.e. the time after current interruption before integration starts), 0.45 sec was chosen to allow enough time for normal electromagnetic effects and any capacitive coupling effects between the transmitter and receiver to attenuate so that the secondary voltage consists only of the IP decay voltage.

Ill

Page 24: ROYAL OAK MINES INC SEMPLE-HUTT PROP 1994 ASSESSMENT …

In many, but not all, prospecting situations, the 450 msec delay before integration is sufficient time for any electromagnetic effects to have decayed away. The gate width is arbitrary but it is generally chosen to be an integral multiple of 60 Hz periods (i.e. 16.7 msec) so that the effect of 60 Hz noise is cancelled in the integration. The Newmont M gate width is 39 periods long while the L parameter is 78 periods long. The Newmont L factor as defined in Figure l is a parameter which helps to signal the presence of anomalous decay curve shape. The ratio of L to M (i.e. L/M) is unity whenever a typical IP decay curve is encountered. When L/M departs significantly from unity in a prospecting situation, the presence of EM coupling is strongly indicated. The reader is referred to Swift (1973) for an analysis of this parameter.

Multiple Gate Time Domain Receivers

The foregoing discussion suggests that there is more information in a time-domain decay curve than a simple chargeability. Indeed, contemporary research in the IP method is now directed toward an analysis of the entire waveform. In order to obtain more information on the decay curve shape, most IP instrument manufacturers make a receiver which is capable of measuring more than one gate along the transient. Figure 3 schematically illustrates one-half of a time domain waveform and 4 arbitrary along the secondary voltage. The gate definitions are arbitrary, subject only to practical considerations mentioned earlier. However, the gates which are farther out in the decay curve necessarily must integrate a signal of much lower amplitude. As a result, it is usual to increase the gate widths by some multiple of the first gate width. Figure 3 suggests a binary increase in the width. Some instruments choose the gate widths and calibration constants so that whenever a decay curve having the standard shape of an IP response is measured, the chargeabilities measured at each gate are the same.

Pole Dipole Array

The use of the Pole Dipole array i s much Jess common then the Dipole Dipole array but it has distinct advantages. The most notable advantage is the much stronger current density obtained from the single current pole on the traverse. This results in the strongest potential voltage measurable from any of the arrays. This stronger signal to noise permits operation in noisier areas and areas of thicker overburden.

This array is set up similar to that of the Dipole Dipole array except that one current electrode is fixed at geometric infinity or lOa ( 10 times the potential dipole ) across strike. The plot point is mid way between the on line current and the centre of the potential electrodes.

lil Ol "l 02 MS Oj Us

*M*k*f Ikt fUttl

ADVANTAGES

1. Good SP rejection. The strong signal to noise ratio effectively eliminates the SP effect*2. Not susceptible to "masking" effects. This is the recommended array in areas of conductive overburden.3. A fairly sensitive and selective array.4. Returns highest Vp of all arrays. Hence it is ideal for work in noisy areas.5. Relatively faster than Dipole Dipole.6. Low inductive coupling.

DISADVANTAGES

1. Asymmetrical response - peak is only over the source when the spacing "a" is less than the depth of investigation. There will occur a double peak with the stronger of the two on the current side of the potential. This requires that moving current be always kept in the same relative position to the measuring dipole.2. Requires communication between current on line and transmitter.

The Motor-Generator Set consists of a reliable Briggs and Stratton

four stroke engine, coupled to a brushless permanent aagnet alter

nator. The transmitter design employs solid-state components both

for pouer switching and control circuits. Output waveforms and

frequencies are switch selectable; square wave continuous for

frequency domain and square wave Interrupted for time domain. The

programmer Is crystal controlled for high stability. While care

still must be taken when working with high voltages, the TSQ-3

features overload, underload and thermal protection for maximum

safety. Stabilization circuitry ensures that the output current

is automatically controlled to within 0.1Z for up to 20Z external

load or 10Z Input voltage variations. Voltage, current and

circuit resistance are presented on a LED digital display.

Basically, the Motor-Generator and Transmitter function 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 in 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 waveform and frequency

selected.

In Table l the maximum output current from the transmitter at certain values of load resistance is given for each position of the output voltage selector switch. The maximum load resistance limit occurs because of the built-in underload protection which shuts off the transmitter if the output is less than 85 mA. Figure 4 is a graph of output current vs voltage.

3. Theory of Operation

Power is supplied to the TSQ-3 transmitter through the alternator input connector from the three phase, 800 Hz alternator driven by {

a single cylinder, 4 stroke 8 HP engine. The main advantages of this brushless, permanent magnet alternator are: high efficiency, high overload capacity, short circuit immunity and minimum main tenance. The 10 m long input cable has four conductors, three for i

the three phases and the fourth to connect the alternator housing and the back pack to the TSQ-3 grounding lug. An additional grounding lug is provided on the mounting frame of the motor- generator which must be grounded as well. :

Figure 5 is a block diagram showing the basic function of the TSQ-3 transmitter.

Two of three input phases are sensed by the Overload Sensors. In case of an overload, the Protection Circuits open the solid-state Input Switches. The same action takes place if the output current drops below 85 mA, which is sensed by the Open Loop Sensor. If the current stabilization range of 20Z is exceeded, the Over-Range Sensor initiates the same action.
