2.5 FIELD INSTRUMENTATION

JVX supplied the following geophysical instruments. Additional information about the instruments may be found in Appendix A.

2.5.1 Gravimeter

The Lacoste and Rhomberg gravimeter is a microgal instrument designed to measure the gravitational field at an accuracy of .01 milligals and a precision of .005 milligals. A milligal is approximately one millionth of the normal gravitational attraction of the earth. A gravity range of 200 mgal can be read.

The drift in this instrument is measured at 1.0 mgal/month and less than .5 mgal/month after one year of operation. This is considered negligible. The accuracy of the observed gravity reading is limited by the accuracy of the elevation and horizontal control, the drift of the instrument and the accuracy of tidal acceleration measurements.

2.5.2 Magnetometer

The Scintrex IGS-2/MP-4 proton precession magnetometer system was used to measure the total magnetic field over the grid. A second base magnetometer monitored the background magnetic field at a location off the survey grid. These base station data were used to make the diurnal correction.

J VX

2.5.3 Chain+Level

This device provides vertical control to an accuracy of , 207o (2 mm/m elevation) and can measure a maximum elevation difference of 15 m. Elevation differences are calculated as a function of the pressure difference between two measuring points. Temperature differences at the measuring points are taken into consideration by the instrument.

2.6 FIELD PROCEDURES (LEVELLING)

Grid lines with station pickets at 50 m intervals were surveyed, and elevations established on hubs placed near the pickets in a suitable location for the gravity operator to take the gravity measurement.

Levelling required two operators. Temporary bench marks were established in order to close all open level loops to an acceptable standard of l part in 5000.

All gravity measurements were taken within 2 hours of reading a base station. Two GSC gravity base stations located along Highway 558 were used.

J VX

3 DATA PROCESSING

3.1 MAGNETICS DATA REDUCTION

Prior to the survey, the two magnetometers were synchronized in order to minimize the reduction error. While the magnetic survey was conducted, base station readings were collected on a continuous basis.

The magnetic field measurements, time and position information were recorded in the instrument's solid state memory at the base station and on the grid. At the end of each day the correction for the diurnal shift was made automatically by either linking the base station magnetometer to the field magnetometer or by dumping each magnetometer to a PC and running appropriate JVX software for the drift correction.

Base station readings were subtracted from survey readings in order to remove the diurnal variation of the magnetic field. Noise spikes caused by steel culverts under the road, were edited out on Line A. These data were then reformatted to mapping format and archived on to a floppy disk.

The station spacing is a constant 12.5 m for the magnetic profiles and irregular (ie. 50- 200 m) for the gravity profiles. Only stations with both magnetic and gravity values were used by the modelling software. It is for this reason that some magnetic samples, in particular single point anomalies, have disappeared on the models plots.

3.2 GRAVITY DATA REDUCTION

At the conclusion of each survey day the data were dumped to a PC and backed up on floppy disk. An archive data file was created after editing repeated or unacceptable readings, field errors and format errors. Gravity data reduction was accomplished by a program called GRAVRED.

Base station gravity readings were taken within two hours and at the start and end of each survey day, in order to correct for instrument drift and temperature variations.

8

Once edited, the gravity data were reduced to a datum plan. This was done by applying latitude, earth-tide, free air and elevation corrections, the formulas for which are in Appendix B.

Latitudes and longitudes obtained from a 1:50,000 topographic map were used to first reduce the data to a theoretical earth reference surface (ie. at mean sea level) or geoid, using JYX software.

A correction was made for the elevation of the survey above this datum. Because the increased distance from the earth's center of gravity to the survey elevation point decreases the observed gravity, a free-air correction was made.

This first elevation correction (i.e., Bouguer correction) compensates for the increased attraction of the mass between the datum and each gravity station (ie. the Bouguer slab). The second elevation correction called the terrain correction is applied when there is severe topographic variation. This is required because of the mass attraction of elevated terrain and negative mass attraction due to mass deficiency of lower elevations surrounding each gravity station. Usually, this correction is unnecessary.

Making the above corrections yields Bouguer gravity data. A curve or surface which coincides with the regional trend is often subtracted from these data to produce a residual gravity profile or surface. For this modelling study, the residual gravity values were used for the modelling component of this study.

Both magnetic and gravity datasets were compiled into a file suitable for the gravity/magnetics modelling package GMSYS. Because the station spacing is a constant 12.5 meters for the magnetic survey and 50-200 meters for the gravity survey, some magnetic readings were discarded during the modelling process.

3.3 GRAVITY and MAGNETIC MODELLING

GMSYS displays a calculated gravity curve (an unbroken line) based on the input geological model along with the observed residual gravity readings. The difference or error between the calculated and observed gravity is also displayed. The total field magnetics is similarly displayed.

The input geological model consists of a number of interconnected polygons, each having attached parameters, the main ones being density and susceptibility. General parameters such as the Bouguer slab density (2.65 g/cc), base magnetic field (57000 gammas), declination (13 degrees), anomaly strike (azimuth 45-90 degrees) and profile azimuth are established before beginning the model. The gravity and magnetic model profiles are calculated using these parameters and assume infinite strike length although in reality this parameter is not infinite as in the case of circular anomalies.

Potential field models in general are ambiguous because an infinite number of geological models produce similar responses. This is the biggest limitation of gravity and magnetic modelling. The geophysical interpretation thus hinges on known geological parameters which help to constrain the model. However, the gravitational model constrains the magnetic model since they are based on the same geological model.

3.4 DATA PRESENTATION

I Toftle plots of the gravity and magnetic data were generated both in the field and in the head office using the GEOPAK Line Processing package.

At the head office, the AUTOCAD computer-aided drafting package was used to add any necessary features (e.g. title block, north arrow).

Plates l and 2 are plots of the magnetic and gravity profiles at a scale of 1:5000 8c l :25000 respectively. Plate 3 is a compilation map of Magnetic X Gravity model at l :20000 scale. Plate 4 is a compilation plot of the topography, magnetics and Residual gravity 1:20000 scale.

3.5 DATA PLOTTING

After being transferred to a field computer at the end of each survey day, the data were examined, corrected, and organized by the instrument operator. Results were plotted on the following printers:

- STAR NX-80 colour dot-matrix printer ' CPSON FX-80 dot-matrix printer

These plots were used to monitor progress and data quality, and to make an initial interpretation. Thus the survey parameters and design were altered when necessary.

Data sets were sent by courier to the head office of JVX in Richmond Hill, Ontario. They were processed and results plotted on the following printers:

- BRUNING ZETA 36 inch pen plotter- TEKTRONIX COLORQUICK ink jet printer- FUJITSU DL2400 colour dot-matrix printer- TEXAS INSTRUMENTS MicroLaser Pro 600 Laser printer

4 INTERPRETATION METHODOLOGY

JVX uses its many years of experience in geophysical interpretation to extract the most accurate information from the data. The procedures involved are simplified for the sake of clarity.

4. l MAGNETICS

Regional data were compared with survey profiles. Geological information was also examined for possible magnetic signatures. A strike direction for the magnetic trend or anomaly was determined for each line of the survey and input as a model parameter. At this point a conceptual model for the magnetic source body was developed.

4.2 GRAVITY

The residual gravity field was interpreted by inspecting the data for anomalously dense bodies, density discontinuities and their depths. Because the wavelength of these anomalies increased with depth of gravitational source, the near surface anomalies were interpreted and modelled after the general trends were determined.

4.3 MODELLING CONSTRAINTS

The magnetic profiles were modelled first using a susceptibility contrast of 0.02 emu/cc for a body whose top is between 600-2200 meters depth. No data on magnetic susceptibilities were available for this study. However, the maximum thickness of the Huronian is approximately 1000m (OGS Report 276) and this thickness was used as a first approximation of the depth to the top of the magnetic source. This source may be a diabase sill which is likely to be located at the contact between the Huronian and the Archean.

The densities used for the gravity model were 2.65 g/cc for the Huronian, 2.8 g/cc for the Archean and 3. l g/cc for diabase dikes and sills. Alluvial deposits such as tills were modelled using a density of 2.3 g/cc. These densities were found to be within the range

11

J VX

of densities of local rock types found in published manuscripts (OGS Report 237, 276). The sill was placed at the Huronian-Archean boundary to be consistent with these published reports.

The gravitational model elements were given zero susceptibility so as not to disturb the magnetic model. The density and geometry of the magnetic body remained constant as the parameters of the gravitational model were adjusted. These restrictions facilitated the fitting of both gravity and magnetic profiles with the same geological model. This is comparable to the geological case where increased magnetite content does not significantly contribute to the overall density of the geological unit while producing a sizable magnetic anomaly.

The north-south lines B, C and D were modelled first. The thicknesses of the geological units where the baseline intersects these lines were transferred to the baseline model and used as fixed points for the geological model.

5 RESULTS and INTERPRETATION

5.1 GENERAL

Magnetic profiles and the observed gravity were plotted on Plates l and 2 at 1:5000 SL 1:25000 scale with posted values. Plate 3 includes the gravity and magnetic profiles as part of the compilation map. This map also displays the thicknesses of the magnetic and gravity sources, referred to as 'magnetic body' and 'dense body' on the models described below. Plate 4 is a compilation plot of observed gravity, magnetics and topography profiles at 1:2OOOO scale. Figures 5 to 8 show the residual gravity and magnetic profiles as well as the geological model which has been developed for each profile.

The regional gravity map for the Cobalt area (OGS map P-2296) shows a prominent gravity high to the west-northwest and a prominent low to the east-south east of the survey grid. The gradient of this field appears to be generally uniform from -32 to -26 mgals within approximately 9 km (length of baseline A) and dipping to the east-southeast.

The observed gravity measurements range from -42 to -28 mgals. There is a significant residual gravity anomaly. The residual gravity field ranges from -40 to -28 mgals. The observed gravity profiles for Lines B.C and D exhibit positive north gradients which are

12

J VX

nearly orthogonal to the regional gradient . This is why the range of measurements changes little from observed to residual gravity.

The magnetic survey grid is dominated by a kidney-shaped magnetic high on the DIGHEM Helicopter Magnetometer survey map. This high is of the order of 2500 gammas and has a strike of approximately 30 degrees.

5.2 GRAVITY/MAGNETIC MODELLING

The modelling results are compiled on Plate 4 which reproduces the gravity and magnetic profiles. The general extent of the geological sources which produce similar gravity and magnetic anomalies as measured in the survey are outlined. This map demonstrates that the gravity and magnetic anomaly sources have similar orientation and extent. These geological features closely parallel the baseline and the existing regional fault pattern which has been reproduced here with slight modification.

Not only are the gravity gradients on the north south lines similar, but there is evidence of a negative gravity response to the small graben which runs through the survey grid from east to west. The regional fault pattern has been altered to reflect the position of the negative gravity anomaly on Line D. The negative gravity anomaly on Line A is slightly out of position with respect to the graben faults but the width of this anomaly suggests a high angle of intersection of the graben with the baseline. The small gravity trough is modelled as a clastic wedge with relatively less dense material.

There appears to be no magnetic response to the graben although some single point anomalies which have been modelled as exposed dikes are near the graben anomaly (eg. Line C, station 900S).

5.2. l LINE A-Baseline (East/West direction)

Line A (Figure 5) is characterized by a broad 2.5 mgal residual gravity high with a low centered about station O. A broad magnetic high with a range in intensity of approximately 1000 gammas coincides with this gravity high. The peak residual gravity is measured east of the north/south lines (east of station O) which suggests that the gravitational source is probably thickest east of the survey grid.

The model has a magnetic source which reaches a maximum thickness of approximately 1200m and tapers to Om past the line in both directions. This source is shallower near Line D and deepest near line B. The magnetic source generally dips to the west as modelled on this line.

A dense body with a maximum thickness of approximately 2100m produces a good fit with the gravity profile. This gravitational body is thickest in the east and fills a wide

basin (approx. 20 km.) in the Archean. The small gravity low centered at station O is modelled as a thickening of the Huronian.

5.2.2 LINE B (north/south - intersection at station O on baseline)

The residual gravity profile for Line B (Figure 6) is inclined (-39.6 to -SOmgals) to the north with a small trough ( l mgal) centered at the baseline intersection ( station O). A magnetic high of approximately 900 gammas is centered near this gravity low.

The magnetic source is modelled as a prismatic body with a north dip and maximum thickness of 900m. It is at the approximate center of a large basin depression.

Two magnetic diabase dikes which extend to the magnetic source have been included in the model to produce the single point anomalies on the magnetic profile.

The basin depression is the source of the gravity anomaly and is centered north of the profile location. This model has the largest residual gravity anomaly within this survey and the deepest basin extent of all the models.

The small trough near the center of the gravity profile is possibly due to the presence of a clay deposit which was reported by the field crew. A number of east-west faults are reported in this area and two faults are adjacent to this clay deposit (OGS Report 237). This provides evidence for a fault mechanism causing small negative gravity anomalies which are observed on the other survey profiles.

5.2.3 LINE C (north/south - intersection at station 1650 on baseline)

Line C (Figure 7) shows a relatively small magnetic anomaly (approx. 400 gammas) and an inclined gravity anomaly similar to Line B. The residual gravity profile displays a smaller range of values, however the peak is l. Smgals higher than at Line B. This feature is modelled by positioning the dense gravitational body closer to the surface. Figure 7 also shows that the dense body is probably smaller than at Line B.

A small trough on the gravity profile (ie. station lOOOSJis likely caused by a near-surface sedimentary wedge similar to the clay deposit on Line B. This feature is located near a small graben and is likely the same graben which intersects Line B.

The magnetic profile has a relatively lower intensity on Line C compared to the other survey lines. Consequently, the magnetic source is deeper and the gradient is lesser on this model. The model shows that the magnetic source occupies the deepest part of the dense basin unit. Relative to adjacent models for Lines B and D, Line C apparently crosses a saddle on the magnetic source.

A large spike on the magnetic profile is modelled by a magnetic diabase dike which extends from the surface to the magnetic body.

5.2.4 LINE D (north/south - intersection at station 5600 on baseline)

The residual gravity range over Line D (Figure 8) is approximately -31 to -35mgals. This is the least anomalous gravity profile within this grid. A relatively small dense body similar to adjacent north-south lines is modelled at the center of a broad Archean basin. A relative increase in the thickness of this dense body and a thinning of the Huronian northward produces the inclined gravity profile. This is consistent with all lines within the grid.

A small gravity trough, similar to Lines A, B and C is also present. The same graben faults, as mentioned above, which are mapped farther to the south (OGS Report 237) may intersect Line D at this gravity trough.

The magnetic intensity falls 800 gammas towards the north. This profile also exhibits the highest gradient of all the profiles in the grid. The model suggests that the magnetic source is relatively shallow (approx. 700m vs. 1200m for Line C). The magnetic source as shown in Figure 8 is large compared to the surrounding gravity source.

There are two positive spikes which may represent magnetic dikes or faults extending from the surface to the magnetic body in this model.

* The survey grid is located on an Archean basin which may have influenced the formation of a dense body such as a diabase sill. This basin is as much as 3000m deep.

* This diabase sill and basin structure is centered in the northeast area of the survey grid and the resulting displacement of less dense rock types has probably caused the observed residual gravity anomaly.

* Within this diabase is a magnetic source which is 600-1200m deep. This magnetic source may be relatively shallow under Line D and deepest under Line C. This magnetic body may extend up to 4 km north of the baseline along Line B.

* The regional fault pattern is apparently related to a small residual gravity low on Line B and C which may be further extended to Line D. This graben trends in an east direction and is infilled with clastic material such as clay or till which produces the gravity low.

* The magnetic and gravity anomalies as modelled and presented in this study appear to be controlled by the same basement feature as shown by the coincident location of the mapped gravity and magnetic source features. The gravity and magnetic anomalies appear to closely parallel the regional fault pattern.

* This study would benefit from additional closely-spaced gravity and magnetic lines and additional geological data in order to further constrain the models. Important parameters would include average densities of the rock types involved in this area and their magnetic susceptibilities. Depth control points of the various structures identified by this study would help to fine-tune the models.

APPENDIX A

Background

to the

Geophysical Methods

MAGNETIC METHOD

The magnetic field measured at any point on or above the earth's surface Is a combination of:

1) the earth's magnetic field,

2) the induced magnetization of near-surface material, and

3) the remanent magnetization of near-surface material.

The total measured field is equal to the vector sum of the magnetic field arising from all three factors.

1 THE EARTH'S MAGNETIC FIELD

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. This field can be considered to be constant in space and time for exploration surveys.

2 INDUCED MAGNETIZATION

An external magnetic field (for example, the earth's) induces the magnetization of a ferrous body. This magnetized body then produces an additional magnetic field, known as the induced field, which is given by the following formula:

where:I s the induced magnetic field (nT) — a vectork = the volume magnetic susceptibility of the materialH s the external magnetic field (nT) — a vector

MAG-1

Thus, the strength of the induced magnetic field is a function of the susceptibility of the body. In turn, the susceptibility is a reflection of the content of ferrous minerals, most importantly magnetite. Note that the induced field is parallel to the external field.

3 REMANENT MAGNETIZATION

The remanent 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 remanent magnetization may bear no relation to the present direction and intensity of the earth's field. The remanent magnetization is related to the direction of the earth's field at the time the rocks were last magnetized. Generally, one can assume that there is no significant remanent magnetization when interpreting magnetic data.

4 DIURNAL CORRECTION

Although the earth's magnetic field is essentially constant, time-varying magnetic fields may result from atmospheric phenomena. Fields due to magnetic storms may vary by hundreds of nanoteslas in a few minutes. Therefore, it is necessary to monitor the background magnetic field constantly using a stationary base station magnetometer. The field measurements can then be corrected for the background magnetic variation. This process is known as diurnal correction.

5 INTERPRETATION

Magnetic data are used to map regions of different magnetic susceptibilities (i.e. ferrous content). The magnetic method cannot detect gold directly, but it can map structures which can aid in locating areas of silicification and carbonization. When used in conjunction with geological and other geophysical data, magnetic data can help select targets which are favourable for economic mineralisation.
