REPORT ON A HELICOPTER-BORNE

VERSATILE TIME DOMAIN ELECTROMAGNETIC SURVEY

Bourdon West, C1, C3, D1, E1, N1, N3, N4, N5, and N6 Blocks Webequie, Ontario

Executive Summary During June 20th to August 26th, 2008 Geotech Ltd. carried out a helicopter-borne geophysical survey for Noront Resources Ltd. over ten (10) blocks situated in the province of Ontario, Canada. Principal geophysical sensors included a versatile time domain electromagnetic (VTEM) system, and a caesium magnetometer. Ancillary equipment included a GPS navigation system and a radar altimeter. A total of 8753 line-kilometres were flown. The survey operations were based out of the McFauld’s Camp and Richard’s Lake Camp located in Ontario. In-field data quality assurance and preliminary processing were carried out on a daily basis during the acquisition phase. Preliminary and final data processing, including generation of final digital data and map products were undertaken from the office of Geotech Ltd. in Aurora, Ontario. The processed survey results are presented as electromagnetic stacked profiles, and as a colour grid of the B-field EM late time channels, total magnetic intensity, calculated magnetic vertical gradient, calculated dB/dt and B-field time constants (Tau). Digital data includes all electromagnetic and magnetic products, plus ancillary data including the waveform. The survey report describes the procedures for data acquisition, processing, final image presentation and the specifications for the digital data set. No formal interpretative discussion is included in this report; however EM anomaly picking, time constant (Tau) analyses and calculated magnetic vertical gradient maps have been added as additional products.

During the survey of the Bourdon West, N1, N4, and N5 blocks the helicopter was maintained at a mean height of 76 metres above the ground with a nominal survey speed of 80 km/hour. This allowed for a nominal EM sensor terrain clearance of 41 metres and a magnetic sensor clearance of 63 metres. During the survey of the N3 and D1 blocks the helicopter was maintained at a mean height of 74 metres above the ground with a nominal survey speed of 80 km/hour. This allowed for a nominal EM sensor terrain clearance of 39 metres and a magnetic sensor clearance of 61 metres. During the survey of the C1 block the helicopter was maintained at a mean height of 78 metres above the ground with a nominal survey speed of 80 km/hour. This allowed for a nominal EM sensor terrain clearance of 43 metres and a magnetic sensor clearance of 65 metres. During the survey of the C3 block the helicopter was maintained at a mean height of 73metres above the ground with a nominal survey speed of 80 km/hour. This allowed for a nominal EM sensor terrain clearance of 38 metres and a magnetic sensor clearance of 60 metres.


During the survey of the E1 block the helicopter was maintained at a mean height of 77 metres above the ground with a nominal survey speed of 80 km/hour. This allowed for a nominal EM sensor terrain clearance of 42 metres and a magnetic sensor clearance of 64 metres. Lastly during the survey of the N6 block the helicopter was maintained at a mean height of 75 metres above the ground with a nominal survey speed of 80 km/hour. This allowed for a nominal EM sensor terrain clearance of 40 metres and a magnetic sensor clearance of 62 metres.

The data recording rates of the data acquisition was 0.1 second for electromagnetics, magnetometer and 0.2 second for altimeter and GPS. This translates to a geophysical reading about every 2 metres along flight track. Navigation was assisted by a CDGPS receiver and data acquisition system, which reports GPS co-ordinates as latitude/longitude and directs the pilot over a pre-programmed survey grid.

The operator was responsible for monitoring of the system integrity. He also maintained a detailed flight log during the survey, tracking the times of the flight as well as any unusual geophysical or topographic feature.

On return of the aircrew to the base camp the survey data was transferred from a compact flash card (PCMCIA) to the data processing computer. The data were then uploaded via ftp to the Geotech office in Aurora for daily quality assurance and quality control by qualified personnel, operating remotely.

2.4 Aircraft and Equipment

2.4.3 Airborne magnetometer

The magnetic sensor utilized for the survey was a Geometrics optically pumped caesium vapour magnetic field sensor, mounted in a separate bird, 13 metres below the helicopter, as shown in Figure 6. The sensitivity of the magnetic sensor is 0.02 nanoTesla (nT) at a sampling interval of 0.1 seconds. The magnetometer sends the measured magnetic field strength as nanoTesla to the data acquisition system via the RS-232 port.

2.4.4 Radar Altimeter

A Terra TRA 3000/TRI 40 radar altimeter was used to record terrain clearance. The antenna was mounted beneath the bubble of the helicopter cockpit (Figure 6). 2.4.5 GPS Navigation System The navigation system used was a Geotech PC104 based navigation system utilizing a NovAtel’s CDGPS (Canada-Wide Differential Global Positioning System Correction Service) enable OEM4-G2-3151W GPS receiver, Geotech navigate software, a full screen display with controls in front of the pilot to direct the flight and an NovAtel GPS antenna mounted on the helicopter tail (Figure 15). As many as 11 GPS and two CDGPS satellites may be monitored at any one time. The positional accuracy or circular error probability (CEP) is 1.8 m, with CDGPS active, it is 1.0 m. The co-ordinates of the block were set-up prior to the survey and the information was fed into the airborne navigation system.

2.4.6 Digital Acquisition System

A Geotech data acquisition system recorded the digital survey data on an internal compact flash card. Data is displayed on an LCD screen as traces to allow the operator to monitor the integrity of the system. The data type and sampling interval as provided in Table 4.

2.4.7 Base Station

A combined magnetometer/GPS base station was utilized on this project. A Geometrics Caesium vapour magnetometer was used as a magnetic sensor with a sensitivity of 0.001 nT. The base station was recording the magnetic field together with the GPS time at 1 Hz on a base station computer. The base station magnetometer sensor was installed where the crew was housed at the McFauld’s Lake Camp, located 89 kilometers south-east of Webequie, Ontario (52° 47’41.0" N, 86° 02’ 54.0” W) 100 meters west of the camp, away from electric transmission lines and moving ferrous objects such as motor vehicles. The base station data were backed-up to the data processing computer at the end of each survey day. The base station magnetometer sensor was also installed at the Richard’s Lake Camp, located 85 kilometers north-east of Webequie, Ontario (53° 11’50.35" N, 86° 07’24.22 W) 100 meters west of the camp, away from electric transmission lines and moving ferrous objects such as motor vehicles. The base station data were backed-up to the data processing computer at the end of each survey day.

4. DATA PROCESSING AND PRESENTATION

Data compilation and processing were carried out by the application of Geosoft OASIS Montaj and programs proprietary to Geotech Ltd.

4.1 Flight Path

The flight path, recorded by the acquisition program as WGS 84 latitude/longitude, was converted into the NAD83 Datum, UTM Zone 16 North coordinate system in Oasis Montaj.

The flight path was drawn using linear interpolation between x, y positions from the navigation system. Positions are updated every second and expressed as UTM easting’s (x) and UTM northing’s (y).

4.2 Electromagnetic Data

A three stage digital filtering process was used to reject major sferic events and to reduce system noise. Local sferic activity can produce sharp, large amplitude events that cannot be removed by conventional filtering procedures. Smoothing or stacking will reduce their amplitude but leave a broader residual response that can be confused with geological phenomena. To avoid this possibility, a computer algorithm searches out and rejects the major sferic events. The filter used was a 16 point non-linear filter.

The signal to noise ratio was further improved by the application of a low pass linear digital filter. This filter has zero phase shift which prevents any lag or peak displacement from occurring, and it suppresses only variations with a wavelength less than about 1 second or 15 metres. This filter is a symmetrical 1 sec linear filter.

The results are presented as stacked profiles of EM voltages for the time gates, in linear - logarithmic scale for both B-field and dB/dt response. B-field time channel recorded at 1.953 milliseconds after the termination of the impulse is also presented as contour colour image. Graphical representations of the VTEM transmitter current waveform output voltage of the receiver coil are shown in Appendix C.

Generalized modeling results of VTEM data, written by consultant Roger Barlow and Nasreddine Bournas, P. Geo., are shown in Appendix E. An explanation of the EM time constant (Tau) calculation is provided in Appendix F.


4.3 Electromagnetic Anomaly section

The EM data were subjected to an anomaly recognition process using all time domain geophysical channels and using both the B-Field and dB/dt profiles. However, based on its enhanced response over high conductance/small area targets, the B-field was relied upon for the EM anomaly selection and analysis process. The resulting EM anomaly picks are presented as overlays on all maps. Each individual conductor pick is represented by an anomaly symbol classified according to calculated conductance3 (Figure 16). The conductances were obtained directly from the EM dB/dt and B-field EM time-constants (Tau)4 using the oblate spheroid conductance model (McNeill, 1980)5 according to specifications provided by the client6 (I. Johnson, pers. comm., 08/07/28). Identified anomalies were classified into one of six categories, base on dB/dt conductance. The anomaly symbol is accompanied by postings denoting the calculated dB/dt conductance, calculated B-field conductance, and the B-field value (time gate 1.953*1007). Each symbol is also given an identification letter label, unique to each flight line; thin types of anomalies are also denoted using a small pink circle. The anomaly symbol legend is given below.

Figure 16 - EM Anomaly Symbols (Symbols on right are only used for the N4 and C3 blocks)

3 Note: The conductances were obtained from the dB/dt and B-field EM time constants (Tau) whose relationships to Tau were calculated using the oblate spheroid model of McNeill (1980) 4 Note: An explanation of the EM time constant (Tau) approach to VTEM data is provided in Appendix F. 5 Ref: McNeill, J.D. (1980). Applications of transient electromagnetic techniques, Technical Note TN.7, Geonics Ltd., Mississauga, ON, 17pp. 6 Note: q/a ratio set equal to 0.0125 for VTEM dB/dt time constant of 3.65 msec and conductivity thickness (δt) equal to 73.2 siemens, over the Eagle One deposit. 7 Note:B-field values for all thin plate anomalies are calculated with the value 1.953*10


EM anomaly symbols are presented in all final maps, i.e. VTEM profiles and total magnetic intensity grid. The anomalous responses have been picked on each line, reviewed and edited by a geophysicist on a line by line basis to discriminate between bedrock, overburden and culture conductors. The new channels were created in each of the Geosoft “XYZ” tables for the block. The identified time domain electromagnetic VTEM anomalies are listed in Appendix G.

4.4 Magnetic Data

The processing of the magnetic data involved the correction for diurnal variations by using the digitally recorded ground base station magnetic values. The base station magnetometer data was edited and merged into the Geosoft GDB database on a daily basis. The aeromagnetic data was corrected for diurnal variations by subtracting the observed magnetic base station deviations. Tie line levelling was carried out by adjusting intersection points along traverse lines. A micro-levelling procedure was applied to remove persistent low-amplitude components of flight-line noise remaining in the data. The corrected magnetic data was interpolated between survey lines using a random point gridding method to yield x-y grid values for a standard grid cell size of approximately 0.25 cm at the mapping scale. The Minimum Curvature algorithm was used to interpolate values onto a rectangular regular spaced grid. The magnetic derivative analyses are obtained using algorithms developed inside the Geosoft MagMapTM platform. These FFT-based analyses are preformed directly onto the Geosoft grids of the final corrected total magnetic intensity.

5.2 Maps

Final maps were produced at scale of 1:10,000 and 1:20,000. Due to the size of some survey blocks and final scale of the maps, some blocks have been spilt into separate maps sheets (see Appendix A). The coordinate/projection system used was NAD 83, UTM Zone 16 North. All maps show the flight path trace and topographic data; latitude and longitude are also noted on maps. Mineral claims, provided by the Ontario Ministry of Northern Development and Mines, are also presented on each map. The preliminary and final results of the survey are presented as EM profiles, a late-time gate gridded EM channel, color magnetic TMI contour maps, color calculated magnetic vertical contour maps, and calculated time constant (Tau) color contour maps.

6. CONCLUSIONS AND RECOMMENDATIONS 6.1 Conclusions

A helicopter-borne versatile time domain electromagnetic (VTEM) geophysical survey has been completed over ten (10) blocks near the town of Webequie in the province of Ontario, Canada. The total area coverage is 791.1 km2. Total survey line coverage is 8753 line kilometres. The principal sensors included a Time Domain EM system and a magnetometer. Results have been presented as stacked profiles, anomaly symbols, and contour colour images at a scale of 1:10,000 and 1:20,000. No Formal interpretative discussion is included but EM anomaly picking, time constant (Tau) analysis and calculated magnetic vertical gradient maps are included.

6.2 Recommendations Based on the geophysical results obtained, a number of interesting EM and magnetic anomalies were identified across the property. We therefore recommend a detailed interpretation of the EM and magnetic data, in conjunction with the geology, using inversion and modelling technique to further characterize the observed anomalies and to more accurately determine their parameters (depth, conductance, dip, etc.) prior to ground follow up and drill testing.

GENERALIZED MODELING RESULTS OF THE VTEM SYSTEM

Introduction

Introduction

The VTEM system is based on a concentric or central loop design, whereby, the receiver is positioned at the centre of a 26.1 metres diameter transmitter loop that produces a dipole moment up to 401,180 nIA at peak current. The wave form is a bi-polar, modified square wave with a turn-on and turn-off at each end. With a base frequency of 30 Hz, the duration of each pulse is approximately 7.3 milliseconds followed by an off time where no primary field is present.

During turn-on and turn-off, a time varying field is produced (dB/dt) and an electro-motive force (emf) is created as a finite impulse response. A current ring around the transmitter loop moves outward and downward as time progresses. When conductive rocks and mineralization are encountered, a secondary field is created by mutual induction and measured by the receiver at the centre of the transmitter loop.

Measurements are made during the on and off-time, when only the secondary field (representing the conductive targets encountered in the ground) is present.

Efficient modeling of the results can be carried out on regularly shaped geometries, thus yielding close approximations to the parameters of the measured targets. The following is a description of a series of common models made for the purpose of promoting a general understanding of the measured results.

General Modeling Concepts

A set of models has been produced for the Geotech VTEM® system with explanation notes (see models C1 to C18). The reader is encouraged to review these models, so as to get a general understanding of the responses as they apply to survey results. While these models do not begin to cover all possibilities, they give a general perspective on the simple and most commonly encountered anomalies.

When producing these models, a few key points were observed and are worth noting as follows:

● For near vertical and vertical plate models, the top of the conductor is always located directly under the centre low point between the two shoulders in the classic M shaped response.


● As the plate is positioned at an increasing depth to the top, the shoulders of the M shaped response, have a greater separation distance. ● When faced with choosing between a flat lying plate and a prism model to represent the target (broad response) some ambiguity is present and caution should be exercised. ● With the concentric loop system and Z-component receiver coil, virtually all types of conductors and most geometries are most always well coupled and a response is generated (see Figures C17 & C18). Only concentric loop systems can map such wide varieties of target geometries.

The Maxwell TM modeling program (EMIT Technology Pty. Ltd. Midland, WA, AU) used to generate the following responses assumes a resistive half-space. Variation of Plate Depth

Geometries represented by plates of different strike length, depth extent, dip, plunge and depth below surface can be varied with characteristic parameters like conductance of the target, conductance of the host and conductivity/thickness and thickness of the overburden layer.

Diagrammatic models for a vertical plate are shown in Figures C-1 & C-2 and C-5 & C-6 at two different depths, all other parameters remaining constant. With this transmitter-receiver geometry, the classic M shaped response is generated. Figures C-1 and C-2 show a plate where the top is near surface. Here, amplitudes of the duel peaks are higher and symmetrical with the zero centre positioned directly above the plate. Most important is the separation distance of the peaks. This distance is small when the plate is near surface and widens with a linear relationship as the plate (depth to top) increases. Figures C-5 and C-6 show a much deeper plate where the separation distance of the peaks is much wider and the amplitudes of the channels have decreased.

Variation of Plate Dip

As the plate dips and departs from the vertical position, the peaks become asymmetrical. Figures C-3 & C-4 and C-7 and C-8 show a near surface plate dipping 80º at two different depths. Note that the direction of dip is toward the high shoulder of the response and the top of the plate remains under the centre minimum.

As the dip increases, the aspect ratio (Min/Max) decreases and this aspect ratio can be used as an empirical guide to dip angles from near 90º to about 30º. The method is not sensitive enough where dips are less than about 30º. For example, for a plate dipping 45º, the minimum shoulder starts to vanish. In Figures C-9 & C-10 and C-11 & C-12, a flat lying plate is shown, relatively near surface.


Note that the twin peak anomaly has been replaced by a symmetrical shape with large, bell shaped, channel amplitudes which decay relative to the conductance of the plate.

In the special case where two plates are positioned to represent a synclinal structure. Note that the main characteristic is that the centre amplitudes are higher (approximately double) compared to the high shoulder of a single plate. This model is very representative of tightly folded formations where the conductors where once flat lying.

Variation of Prism Dip

Finally, with thicker, prism models, another algorithm is required to represent current on the plate. A plate model is considered to be infinitely thin with respect to thickness and incapable of representing the current in the thickness dimension. A prism model is constructed to deal with this problem, thereby, representing the thickness of the body more accurately.

Figures C-13 & C-14 and C-15 & C-16 show the same prism at the same depths with variable dips. Aside from the expected differences asymmetry prism anomalies show a characteristic change from a double-peaked anomaly to single peak signatures.

General Interpretation Principals

Magnetics

The total magnetic intensity responses reflect major changes in the magnetite and/or other magnetic minerals content in the underlying rocks and unconsolidated overburden. Precambrian rocks have often been subjected to intense heat and pressure during structural and metamorphic events in their history. Original signatures imprinted on these rocks at the time of formation have, it most cases, been modified, resulting in low magnetic susceptibility values.

The amplitude of magnetic anomalies, relative to the regional background, helps to assist in identifying specific magnetic and non-magnetic rock units (and conductors) related to, for example, mafic flows, mafic to ultramafic intrusives, felsic intrusives, felsic volcanics and/or sediments etc. Obviously, several geological sources can produce the same magnetic response. These ambiguities can be reduced considerably if basic geological information on the area is available to the geophysical interpreter. In addition to simple amplitude variations, the shape of the response expressed in the wave length and the symmetry or asymmetry, is used to estimate the depth, geometric parameters and magnetization of the anomaly. For example, long narrow magnetic linears usually reflect mafic flows or intrusive dyke features. Large areas with complex magnetic patterns may be produced by intrusive bodies with significant magnetization, flat lying magnetic sills or sedimentary iron formation. Local isolated circular magnetic patterns often represent plug-like igneous intrusives such as kimberlites, pegmatites or volcanic vent areas.

Because the total magnetic intensity (TMI) responses may represent two or more closely spaced bodies within a response, the second derivative of the TMI response may be helpful for distinguishing these complexities. The second derivative is most useful in mapping near surface linears and other subtle magnetic structures that are partially masked by nearby higher amplitude magnetic features. The broad zones of higher magnetic amplitude, however, are severely attenuated in the vertical derivative results. These higher amplitude zones reflect rock units having strong magnetic susceptibility signatures. For this reason, both the TMI and the second derivative maps should be evaluated together.

Theoretically, the second derivative, zero contour or color delineates the contacts or limits of large sources with near vertical dip and shallow depth to the top. The vertical gradient map also aids in determining contact zones between rocks with a susceptibility contrast, however, different, more complicated rules of thumb apply.


Concentric Loop EM Systems

Concentric systems with horizontal transmitter and receiver antennae produce much larger responses for flat lying conductors as contrasted with vertical plate-like conductors. The amount of current developing on the flat upper surface of targets having a substantial area in this dimension, are the direct result of the effective coupling angle, between the primary magnetic field and the flat surface area. One therefore, must not compare the amplitude/conductance of responses generated from flat lying bodies with those derived from near vertical plates; their ratios will be quite different for similar conductances.

Determining dip angle is very accurate for plates with dip angles greater than 30º. For angles less than 30º to 0º, the sensitivity is low and dips can not be distinguished accurately in the presence of normal survey noise levels.

A plate like body that has near vertical position will display a two shoulder, classic M shaped response with a distinctive separation distance between peaks for a given depth to top.

It is sometimes difficult to distinguish between responses associated with the edge effects of flat lying conductors and poorly conductive bedrock conductors. Poorly conductive bedrock conductors having low dip angles will also exhibit responses that may be interpreted as surficial overburden conductors. In some situations, the conductive response has line to line continuity and some magnetic correlation providing possible evidence that the response is related to an actual bedrock source. The EM interpretation process used, places considerable emphasis on determining an understanding of the general conductive patterns in the area of interest. Each area has different characteristics and these can effectively guide the detailed process used.


The first stage is to determine which time gates are most descriptive of the overall conductance patterns. Maps of the time gates that represent the range of responses can be very informative.

Next, stacking the relevant channels as profiles on the flight path together with the second vertical derivative of the TMI is very helpful in revealing correlations between the EM and Magnetics.

Next, key lines can be profiled as single lines to emphasize specific characteristics of a conductor or the relationship of one conductor to another on the same line. Resistivity Depth sections can be constructed to show the relationship of conductive overburden or conductive bedrock with the conductive anomaly. ___________________ Roger Barlow Consultant ___________________ Nasreddine Bournas, P.

APPENDIX F

EM TIME CONSTANT (TAU) ANALYSIS

Theory As established in electromagnetic theory, the magnitude of the electro-motive force (emf ) induced is proportional to the time rate of change of primary magnetic field at the conductor. This emf causes eddy currents to flow in the conductor with a characteristic decay, whose Time Constant (Tau) is a function of the conductivity and geometry of the survey target. The decaying currents generate a proportional secondary magnetic field, the time rate of change of which is measured by the receiver coil as induced voltage during the Off time. The receiver coil output voltage (e0) is proportional to the time rate of change of the secondary magnetic field and has the form,

e0 α (1 / τ) e – (t / τ)

Where, τ = L/R is the characteristic time constant of the target R = resistance L = inductance

From the expression, conductive targets that have small value of resistance and hence large value of τ yield signals with small initial amplitude that decays relatively slowly with progress of time. Conversely, signals from poorly conducting targets that have large resistance value and smallτ, have high initial amplitude but decay rapidly with time 1

1. EM Time Constant (Tau) Calculation The EM Time-Constant (TAU) is a general measure of the speed of decay of the electromagnetic response and indicates the presence of eddy currents in conductive sources as well as reflecting the “conductance quality” of a source. Although Tau can be calculated using either the measured dB/dt decay or the calculated B-field decay, dB/dt is commonly preferred due to better stability (S/N) relating to signal noise. Generally, TAU calculated on base of early time response reflects both near surface overburden and poor conductors whereas, in the late ranges of time, deep and more conductive sources, respectively. For example early time TAU distributions in an area that is indicative of conductive overburden are shown in Figure 1.

If TAU is calculated across a wide range of time it becomes an integrated parameter and can be used to differentiate conductive sources (Figure 2).

Figure F2 - Map of B-field (left) and TAU (right) with EM anomaly picks due to deep conductive targets.

There are many advantages of TAU maps:

- Because TAU is time integral parameter, all conductive zones and targets are displayed independently of their depth and conductivity on a single map.


- Very good differential resolution in complex conductive places with many sources with different conductivity.

- Signs of the presence of good conductive targets are amplified and emphasized independently of their depth and level of response accordingly.

- Targets which create negative responses in certain known geologic situations, for example due to the relative location of the target, the conductive cover and the coincident geometry of the VTEM system, will usually produce a positive TAU.

In the example shown in Figure 3, three local targets are defined, each of them with a different depth of burial, as indicated on the conductivity depth image (CDI). All are very good conductors but the deeper target (number 3) has a relatively weak dB/dt signal yet also features the strongest total TAU (Figure 4). This example highlights the benefit of Tau analysis in terms of an additional target discrimination tool.

Figure F4 – Map of total TAU and dB/dt profile.

The EM Time Constants for dB/dt and B-field were calculated using the “sliding Tau” in-house program developed at Geotech, using a method similar to the “adTau” of Witherly and Irvine (Condor Consulting Ltd., Lakewood, CO). The EM decays are obtained from all 24 available decay channels, starting at the latest channel (ch33). Time constants are taken from a least square fit of a straight-line (log/linear space) over the last 4 gates above a pre-set signal threshold level (Figure F5). Threshold setting for the current project were 0.0075 pV/A*m4 for dB/dt and 0.015 pV*ms/A*m4 for B-field. The sliding Tau method determines that, as the amplitudes increase, the time-constant is taken at progressively later times in the EM decay. Conversely, as the amplitudes decrease, Tau is taken at progressively earlier times in the decay. If the maximum signal amplitude falls below the threshold, or becomes negative for any of the 4 time gates, then Tau is not calculated and is assigned a value of 0.0ms by default.
