I Introduction

Between November 13th 2007 to December 18th 2007 and January 11th 2008 to February 4th 2008, Fugro Airborne Surveys conducted a HeliGEOTEM® II electromagnetic and magnetic survey of the Adelaide, King, Bay, and York Properties on behalf of MacDonald Mines Exploration Ltd. Using Webequie, Ontario as the base of operations 6,344 line kilometres of data were collected using two survey systems carried by an AS-350 B2 Helicopter and an AS-350 B3 Helicopter (similar to helicopter shown in Figure 1). The interpretation is presented in colour on paper and GEOSOFT digital map files. A complete processing report is presented as a separate document. Refer to the processing report for more details on the survey and system specifications as well as information on the data processing and final products. The following appendices to the processing report are of particular interest to the interpretation:

III INTERPRETATION

General Magnetic Theory The Earth's magnetic field, which changes from over 60,000 gammas in a vertical direction at the poles to about 30,000 gammas in a horizontal direction at the equator, induces a secondary magnetic field in rock bodies containing ferromagnetic minerals. It is this property to become magnetized by an external field that is described as the susceptibility of a rock. Some rocks contain a natural or thermoremanent magnetization that was acquired when the rock was last heated above the Curie point and subsequently cooled. The direction of this remanent magnetization is parallel to the magnetic field that prevailed during the cooling period. These fields, both the induced and remanent, disturb the otherwise smooth magnetic pattern of the Earth's field, and it is these perturbations that are of prime interest in aeromagnetic interpretation. The crystalline rocks of igneous or high-grade metamorphic origin, such as granite, basalt, gneiss and schist, usually contain sufficient quantities of ferromagnetic minerals (mainly magnetite) that their influence on the earth's field can be observed even when covered by sedimentary sections thousands of feet thick. The magnetic pattern over large areas of a single rock type is generally consistent throughout, and whenever the magnetic character changes, it usually implies a change in the rock composition. For example, the contact between a granitic mass and an ultrabasic unit can usually be precisely positioned where the magnetic pattern begins to change from the usual quiet character of granite to the more disturbed pattern of an ultrabasic rock body. The study of magnetic anomalies does, to some degree, depend upon the latitude; in high latitudes attention is devoted to positive anomalies, while at the equator negative anomalies are of prime interest. This is due to the inclination of the earth's magnetic field, which is near vertical, 90°, at the poles, horizontal, 0°, at the equator, and about 77 ° north in this survey area. In such a steep magnetic inclination, the strike of a magnetic body has little effect upon the magnitude and symmetry of the anomaly it produces. An E-W dyke will be primarily positive, with a very weak negative on its north side. The same dyke striking magnetic north (azimuth 353 in this area) will be a symmetrical positive, but only about 95% of its E-W amplitude.

Magnetic Interpretation Procedures In the basic electromagnetic interpretation, magnetic features in the vicinity of conductive targets are studied with regard to shape, size, strike and grouping to aid the evaluation of conductors and their potential correlation with basement. Basement lineaments relating to EM conductors are shown on the interpretation maps.

Overview of the Magnetic Field The survey areas lie in a magnetically active area in the vicinity of the “ring of fire” in the James Bay lowlands. Most of the strong magnetic features lying around the survey areas are generated by mafic to intermediate metavolcanics1 and Archean ultramafics.

Overview of the Electromagnetic Field Optimal products for the areas were selected and generated from the EM data, these products are: Adelaide Bay • EM Anomalies • EM Anomalies • Apparent Conductivity dB/dt Z channel 7 • Apparent Conductivity dB/dt Z channel 7 • Apparent Conductivity B-field Z channel 6 • Apparent Conductivity B-field Z channel 15

King York • EM Anomalies • Apparent Conductivity dB/dt Z channel 7 • Apparent Conductivity dB/dt Z channel 6 • Apparent Conductivity B-field Z channel 8

Apparent Conductance

The apparent conductivity was calculated by fitting channel specified channel of the dB/dt or B Field Z-coil response to the homogeneous-half-space model. Prior to the fitting, the data is deconvolved to the step response in order to provide a linear relationship as the conductivity of the ground increases from the resistive limit to the inductive limit. The apparent conductivity provides the maximum information on the near-surface conductivity of the ground which, when combined with the magnetic signature, provides good geological mapping.

Electromagnetic Anomaly Selection Traditionally with fixed-wing, towed-bird TDEM systems, such as GEOTEM and MEGATEM, the EM anomaly selection is done using the response from the X-coil data by fitting the peak amplitudes of the anomalies to a set of nomogram curves based on the vertical plate model. This allows for the determination of depth and conductivity-thickness-product (CTP) of the conductor (assuming, of course, that the vertical plate model is a valid representation of the conductive source). This is made possible by the fact that, due to the geometry of the fixed-wing, towed-bird systems, the peak of the X-coil response will correspond to the axis of a vertical plate-like conductor. However, with the HeliGEOTEM response, because of the difference in the Tx – Rx geometry, neither the response from the X or Z coil will peak over the axis of the conductor. Instead, over a vertical conductor, the response will show a cross-over on the X-coil and a minima on the Z-coil. Because of this, the anomaly peaks with the HeliGEOTEM data cannot be used to fit to the reference nomogram to derive CTP and depth-to-source. The EM anomaly map provided and used for the interpretation is instead an anomaly trend map which simply shows the locations of the anomaly peaks from the Z-coil response (from either the dB/dt or B-Field response) with an indication of the number of channels deflected. There is no fitting to a nomogram allowing for the calculation of CTP and depth-to-source. In the EM anomaly listing, provided as an appendix to this report, the UTM coordinates given correspond to the locations of the anomaly peaks but not the conductor axis. As part of the interpretation, where an anomaly response is judged to represent a vertical conductor, the assumed position of the conductor axis is shown on the map by the axis that is drawn. In the profile example below, showing HeliGEOTEM responses measured over vertical conductors, the locations of the EM anomalies shown on the map and the corresponding UTM coordinates given in the anomaly listing would correspond to the positions marked by a P. The interpreted position of the conductor axes are shown at the locations marked A.

Where the anomaly is suitably well defined and not overly disturbed by the presence of other closely spaced conductors, the EM response can be modeled interactively using a routine called EMQ which provides information on the position of the conductor, its depth below surface, its strike and dip as well as the conductivity of the source. Refer to Appendix A.

Electromagnetic Interpretation Procedures The general approach to EM interpretation is two-fold. One is to work from the data in plan form (maps), correlating back to the data in profile form; the other is to work from the profiles back to the maps. The basis of target selection is to look for "anomalous" responses. Some of these will stand out on the maps as somewhat isolated features along (hopefully) favourable structural intercepts. Conversely, some localized changes in conductivity may only be apparent in profile form and may not stand out on the maps due to surrounding conductivity. So, a general review of the EM anomalies in profile form is done to search for well-defined symmetrical shape, moderate amplitude, slow decay, etc., then checked on the maps for strike length, structural (magnetic/geologic) support and overall conductivity pattern. The conductor axes and zones were compared with the magnetic signature to separate the basement conductors from those arising from overburden. The magnetic signature over a shield area arises almost exclusively from the crystalline basement. Two levels of correlation with magnetic/geologic basement were noted: - structurally favorable (along contacts, intersected by faults, near intrusives, etc.); - coincidence of EM and magnetic bodies of similar dimensions. At the end of this process, the EM selections will normally fall into six groups, which will be: Based on the EM signature A. Anomalous on the maps and having good anomaly characteristics in profile form; B. Non-distinct on the maps but having good anomaly characteristics in profile form;

C. Anomalous on the maps but lacking good anomaly characteristics in profile form; Based on the Magnetic signature

1. With a magnetic coincidence suggesting a common source; 2. Showing evidence of structural control from the magnetic signature; 3. Showing no support from the magnetic signature. These six groups will then be recombined into nine categories, ordered in terms of their potential as massive sulphide or mineral targets, A-1 having the greatest potential to C-3 having the least potential.

Categories: A-1, A-2, A-3, B-1, B-2, B-3, C-1, C-2 and C-3 The EM responses discussed in the following section identify those anomalies, which generally met the criteria associated with possible mineralization. The category assigned to each selection is based on the criteria outlined above which can be summarized by the table below:

As some of the conductor axes are quite extensive, often crossing many survey lines, classification will be done on a selection of anomalies that represent the highest priority points of the bodies, instead of classifying each anomaly on every line separately which may at times be redundant. Conductors listed that do not have a classification assigned are generally bodies that display poor plan view response and profile expression and therefore do not fit into the A, B or C groups. However, these conductors do display evidence of weakly conductive properties and are included in the conductor list. A reminder that category A-1 identifies the greatest potential for mineralization with the priority dropping to category C-3 having the least potential. Refer also to Appendix B of the Logistics and Processing Report (Airborne Transient EM Interpretation), which provides more general information on the interpretation of time-domain electromagnetic data.

Conductors in the Survey Areas Significant conductors within the survey areas have been outlined on the interpretation map and are described below. The conductors are classified as conductive zones, points and axes. An axis describes a conductor that displays a relatively narrow, linear feature with defined profile response, often with indication of vertical extent. Single point anomalies are generally notable responses seen only on one line, and depending on their strength and the survey line spacing, can often be considered good exploration targets. Areas interpreted as conductive zones are generally broad conductors displaying a well-defined boundary on at least one of the EM grids, in this case the apparent conductivity and channel amplitude grids. Potential faults and basement lineaments are shown on the interpretation map in the vicinity of the conductors described below. Due to the abundance of strong magnetic response, the first vertical derivative grid is displayed as the base grid in order to help show the extent of the magnetic/electromagnetic correlation.

Appendix A - EMQ Modeling Results

The modeling with EMQ is done from the “Moment” data, which is itself calculated from the B-Field response. As such, weaker conductors which have a short time constant and a poorer B-Field response will generally not provide a sufficiently good signature on the derived Moment response to allow reliable modeling of the anomalies. Also, in order to be able to fit a response with a reasonable degree of confidence, the anomaly itself must be well defined with a minimum of disturbance from neighboring conductors. This means that, in order to be able to able to model an anomaly successfully, it must be a singular response and relatively isolated. A strong response, which is part of a cluster of anomalies, may not provide reliable modeling results if is too disturbed by the effect of nearby conductors. Notes on the EMQ presentation:

• The BLUE profile trace represents the measured response. • The RED profile trace represents the model results • The cross-section window shows a “sphere” which is the default model used by the

application. However, in this case, the simulated “plate” response was used to better reflect the linear – elongated nature of the responses. This is done by channeling all the current flow along one plane of the sphere, thus simulating the response from a plate. The outline of the plate corresponds to the plane drawn through the sphere.

• In the profile windows, the right-hand side of the image always corresponds to either North or East.

• The three profile widows, Top, Middle and Bottom, correspond to the response from the X, Y and Z coil respectively, or when modeling different moments from the same component would correspond to the 2nd, 3rd and 4th moment of the Z coil for example.

• EMQ solves for the following parameters: Position, depth, conductivity, dip, strike and diameter. When using the simulated “plate” response, the value of the “diameter” is a reflection of the total surface area of the conductor and is not an indication of the width of the conductor.

• If an “offset” is noted, this is relative to the flight line. However, the position given is correct and reflects the offset.

General comments about the modeling: As is the case for all modeling, the better the fit, the more confident the results. Although the “sphere” model is the fundamental model used by the program, the simulated” plate response is more commonly used to best approximate the conductors. Looking closely at the differences between the measured and modeled profiles, one often notes that the actual measured data, although it may have the same general shape and amplitude, displays a much more complex profile shape with numerous additional inflexions. This likely reflects the fact that the actual conductor is not homogeneous but rather made-up of numerous smaller conductive lenses and stringers which, as a volume, occupy a space that can be reasonably well approximated by a single enclosing “plate”. This results is an anomaly which has a composite shape that should correspond fairly well to the plate parameters used by the modeling. It is also important to remember that the GEOTEM and

Page 17: Fugro Airborne Surveys BASIC EM INTERPRETATION REPORT and … · 2017. 1. 16. · 4 I Introduction Between November 13 th 2007 to December 18 2007 and January 11 th 2008 to February

17

MEGATEM systems have a very large footprint (in the order of 400 to 500 m) and will tend to homogenize the conductive responses into a single response. This may result in depth estimates which are a bit too deep. The reporting of the depth estimates As mentioned, the fundamental model used by EMQ is the “sphere” model, although the response from a “plate” can be simulated by restricting the flow of EM currents to channel through a single plane of the sphere. However, the reader should be aware that the depth value reported by the program always refers to the top of the sphere, regardless of whether the “sphere” or “plate” model was used in the fitting. In the case of the plate model, the depth value given will reflect the top of the plate if the plate is vertical and will be close to the top of the plate for a steeply dipping plate. However, in the case of a shallow dipping or flat-lying plate, the actual depth to the plate itself will be closer to the depth value given “plus” half of the diameter of the sphere.

In the modeling results provided, if the simulated “plate” model was used in the fitting, then two depth values are given, one for the top of the “enclosing” sphere and one for the approximate depth of the plate which corresponds to the depth to the top of the sphere plus half of the diameter. The modeling approach used Like any modeling software, EMQ does not necessarily provide a unique solution. Often, several different solutions will give very comparable fits. The shape of an anomaly (comparing the differences and relative symmetries between the 2 or 3 components used, X and Z or X, Y and Z) is defined by the orientation of the body (strike, dip and offset from the flight line). Any change in these parameters will have a direct effect on the resulting shape of the anomaly such that the orientation of the body can usually be determined with very little ambiguity. The amplitude of the anomaly (and to some degree its wavelength) on the other hand, is controlled by the “conductivity-volume” and the depth to source. Here, multiple solutions can exist. A large diameter sphere of low conductivity and close to surface will give a very similar response to a much smaller diameter sphere of higher conductivity at greater depth. If one of these parameters is known, such as the diameter of the sphere or its conductivity, then the depth to source can be determined with little ambiguity. However, if all 3 parameters are unknown, then we’re back to multiple solutions.

The following approach to the modeling was used to reduce these ambiguities:

• Initially, 2 components (X and Z) of a given order (the 2nd order for example) were modeled in order to define the orientation of the body (strike, dip and offset from the line). On extensive axes that cross multiple survey lines, the strike was often determined directly from the map and fixed. Shorter axes or single point anomalies with less confidence on strike determined from the maps relied more on the strike determined from the modeling results.

• Then, as a second pass, having determined the orientation of the body at step 1, two or

more orders of the same component were modeled simultaneously (2nd, 3rd and 4th Moment of Z, for instance). Generally, the response from the best fitting component was used for this. The scalar differences in the amplitude of the response between the different order of moments will identify which of the alternatives is the most plausible. Since the orientation of the body cannot be determined very well from a single component, the values of dip, strike and offset obtained at step 1 were simply entered and fixed. Only the depth, diameter and the conductivity parameters were inverted.

When applicable, results from both steps are provided. *******************************************************
