4. RESULTS AND SUMMARY INTERPRETATION

PREFACE

The Interpretation of exploration data requires combining different types of information to provide a geologic model. It implies bringing together all data components into an image that makes conceptual sense in terms of the geology of the exploration area. The identification of geologic objects and the inference of a spatial description of the lithology—consistent with all available information—are the objectives of the process. The more information that can be utilized, the greater the degree of confidence is going to be in the model generated (more certain is the result of the inference). The interpretational process should serve to combine different types of geophysical data, petrophysical

information on the rock properties, and information on the geology of the area.

INTRODUCTION TO GRADIENT SURVEYS

The gradient array survey results are relied upon as a bulk conductivity\chargeability mapping tool and large transmit dipoles employed provide significant depth of investigation in the central region of the grid and the relatively narrow receiver dipoles also offer significant lateral resolution, but are none the less subject to significant volume averaging.

Based on the array geometry chosen, gradient reconnaissance investigation depth approaching 300 meters were obtained - with the deepest penetration in the middle third of the array and shallower depths of investigation progressively closer to the transmit electrodes. The gradient apparent resistivity and chargeability data therefore represent a bulk average, from surface to depth, when observed in plan view. Additionally, the gradient array anomaly patterns are essentially sub-vertical (i.e. without complex, asymmetric pant-leg shapes, as in pdp and dpdp), and can be visualized in plan in the same manner as magnetic or gravity data. However, in the presence of moderate to shallow dips, the gradient array anomalies tend to be shifted down-dip relative to shallower arrays, such as pole-dipole – greater discrepancies can also occur with dipole-dipole, owing to the asymmetric array geometry, which tends to bias anomalies towards the infinity pole.

GRADIENT PLAN MAP RESULTS

The following discussion summarizes the results of the Gradient TDIP \ Resistivity survey over the PAGWACHUAN LAKE - GRID 1, undertaken by MATRIX GEOTECHNOLOGIES LTD in August 2011 , with induced polarization parameter able to detect and discern mineralization ranging from disseminate to massive concentrations and resistivity data mostly characterizing the geological structures.

IP\Resistivity results over the PAGWACHUAN LAKE - GRID 1 successfully define the geophysical signatures potentially associated to lithologic changes, structures, and chemical alteration. Total chargeability and apparent resistivity show that the property is generally characterized by relatively high resistivity, especially to the grid center and SW, suggesting the predominance of low conductivity geological units, such as mafic units and felsic\qtz\carbonate alteration and weak chargeability responses at depth.

The authors would like to emphasize the fact that the induced polarization phenomena, although generally less intense, is also found in the absence of electrically conductive bodies (known as non-metallic or electrolytic IP). To explain electrolytic IP, one often considers the presence of clay particles, whose surface would be charged negatively and hence would induce an accumulation of cations in the electrolyte. However, it is quite possible that the increase of secondary mineralization in the rock, might as well give considerable chargeability responses, such is the case of pyroxenite.


P-236 – November 2011 13

Figure 4: Total Chargeability Plan Map over Pagwachuan Lake – Grid 1

Induced polarization data indicate the occurrence of metallic/electronic and electrode chargeability. This phenomenon may be observed in electrically conductive bodies and/or non-metallic/electrolytic /membrane IP, which is also found in the absence of electrically conductive bodies. Consequently, the IP map might represent the distribution of metallic and non-metallic responses.

The gradient total chargeability responses at PAGWACHUAN LAKE - GRID 1 (Figure 4) are characterized by wide range in strength, varying between questionable\weak to very strong but generally falling in the weak category (avg. 4.1 mV/V) – consistent with weakly mineralized environment, with the peaks most likely corresponding to higher mineralization content\IF\graphite at depth. In addition, it is important to emphasize that the chargeabilities seem to be stronger to the grid south, likely representing increase sulphide\IF\graphite\argillitic content. Statistical analysis of total chargeability parameter shows that only 8 % of total chargeability data falls in moderate to strong category and almost 85 % falling in questionable to weak category, suggesting low contrast of IP anomalies over the background.

Total chargeability plan map shows the presence of several, chaotic and not line-to-line correlated induced polarization signatures, most likely related to the weak presence of sulphides or argillitic content or graphite e.g. the very strong induced polarization signature south of L.4+00E.


P-236 – November 2011 14

Figure 5: Apparent Resistivity Plan Map over Pagwachuan Lake – Grid 1

Apparent Resistivity data (Figure 5) display a wide range, varying between 277 ohmm and 34.7 kohmm (avg. 2.6 kohmm); indicative of relatively low porosity bedrock at depth – with the average consistent with compact sediments\metamorfic rocks. The apparent resistivity data define high resistivity almost NE-SW trending zones, interpreted as diabase\qtz\carbonate altered dykes or volcanics. The very high resistivity values possibly reflect the shallow occurrence of volcanics or dykes. High resistivity zones are relatively thin, with the exception of some localized high resistivity zones, and long trending generally showing very good line-to-line correlation; however local breaks and displacements are observed suggesting aggressive tectonic activity.

Statistical analysis of apparent resistivity shows that over 75% of resistivity data falls in low to moderate category, indicator of porous rocks at depth.

PDP SURVEY DESCRIPTION

Pole-Dipole (PDP) array (n=2a, a=25 m, dipole 1 to 6) was used as follow-up detailing tool over the most prominent gradient anomalies at PAGWACHUAN LAKE - GRID 1. Detailing survey was conducted over L.4+00E, L.5+00E, L6+00E and L7+00E. The following represents a brief description of Pole-Dipole


P-236 – November 2011 15

survey.

Pole-Dipole survey shows that the total chargeability is characterized by questionable chargeability signatures, with anomalous chargeabilities ranging from 6 mV/V to 12.7 mV/V, usually indicator of weak to moderate mineralization concentration. Surveyed data show the presence of moderate induced polarization anomalies to the south of surveyed lines, except for L.7+00E, generally associated with high resistivity, indicator of mineralized qtz\carbonate alteration. However, low resistivity induced polarization anomalies are observed as well, more specifically on L.6+00E, generally indicator of VMS.

TOTAL FIELD MAGNETIC DATA INTERPRETATION

The fundamental factor influencing potential field anomalies is the mineralogy of the rocks, which control magnetic susceptibility. The magnetic field is controlled by the accessory minerals in a rock, principally magnetite and their distribution may not be uniform for various reasons: concentration in distinct layers; uneven hydrothermal alteration etc.

Figure 6: Total Magnetic Field Plan Map over Pagwachuan Lake – Grid 1

Magnetic survey is a proven efficient tool in mineral\iron prospecting and\or the delineation of geological


P-236 – November 2011 16

contacts between intrusive rocks and sedimentary units. Sedimentary rocks usually exert such a small magnetic effect compare to the intrusives that most variations in magnetic intensity measurable at the surface result from intrusive rocks.

Ground total field magnetic results on the PAGWACHUAN LAKE - GRID 1 (Figure 6) display relatively wide variation in Total Field Magnetic (TFM). The diurnally and loop corrected magnetic contour maps are dominated by disturbances most likely related to the local disturbances and less to major geological changes (broad scale signatures).

The TFM disturbances are mostly observed north and center of surveyed grid, suggesting high content of magnetic material in the area and clearly forming long trending magnetic lineaments that seem to line-to-line correlate.

FFT PROCESSING

Vertical Derivative transforms are intended to facilitate the interpretation of gravity and magnetic maps. They are enhancement techniques which amplify the shorter wavelength features relatively to those with longer wavelengths. Vertical derivatives of any order may be prescribed. The higher the order the greater is the relative amplification of higher frequencies and greater too is the risk of accentuating noise to an unacceptable degree. For this reason vertical derivatives of order three and above are hardly ever calculated. Thus the First Vertical Derivative (FVD) and second vertical Derivative (SVD) transforms are the only transforms of this type that are routinely generated. The first vertical derivative can be used as an alternative to a residual display. The SVD or FVD are calculated using a filtered and unmasked grid of magnetic anomaly.

The following briefly discusses the FFT processing results of gridded data:

High Pass First Vertical Derivative (FVD) of RTE Data): Designed specifically to enhance the shallowest geologic sources in the data. As with other filters that enhance the high-wavenumber components of the spectrum, low-pass filters are applied to remove high-wavenumber noise.

In order to remove the directional ringing problems caused by the gridding process, a directional cosine filter was used and highly directional features can be isolated. The First Vertical Derivative of magnetic data shows the presence of NE-SW magnetic trends, especially to the grid north and center. Minor displacement or breaks are observed, but no major faults are interpreted from the FVD plan map.

High Pass Second Vertical Derivative (SVD) of RTE Data: The primary property of the SVD transform is that the ZERO CONTOUR represents the point of inflexion on the original anomaly curve which approximates the locations of edges of the causative bodies, providing that the bodies are shallow and have vertical sides. A series of SVD processing was undertaken however the FFT result were not different from the FVD results, previously described.

5. CONLUSION AND RECOMMENDATIONS

Gradient\Pole-Dipole time domain induced polarization \ resistivity and magnetic surveys over the PAGWACHUAN LAKE - GRID 1 have identified geophysical signatures, potentially related to lithologic contacts or geochemical alteration, fault-fracture, structures and, most importantly, the presence of increased chargeability, potentially related to mineralization.

The authors have the opinion that the combination of gradient array with pole-dipole array aggregate is a very efficient exploration tool, emphasizing the merit of pole-dipole configuration.

MATRIX GEOTECHNOLOGIES LTD will undertake a more detailed data interpretation, including possible geoscientific data integration and visualization.

Induced Polarization and Resistivity responses at PAGWACHUAN LAKE - GRID 1 can be divided, based on their associated resistivity and strength, in: disseminated mineralization type and MS type\mineralization along sheared zone\ contact type.

Disseminated mineralization type of interest is characterized by increased chargeability associated to high\nil\contact resistivity.

Argillitic\Graphite\MS\sulphide bearing type of signatures is characterized by increased chargeability associated to conductive host (low resistivity).

Prominent Induced Polarization responses in plan range from weak to strong, most likely suggesting moderate content of sulphides\Fe+2 rich rocks in the property

Magnetic survey over the PAGWACHUAN LAKE - GRID 1 accurately contours the presence of increased phyrrotite\ pyroxenite\IF or increase Fe2+ presence.

Considering the complexity of geological model and styles of mineralization, the authors strongly recommend undertaking secondary discriminative methods such as geochemistry\MMI surveys over most prominent geophysical targets in order to better select DH targets.

THEORETICAL BASIS AND SURVEY PROCEDURES

GRADIENT TDIP SURVEYS

The Gradient Array measurements are unique in that they best represent a bulk average of the surrounding physical properties within a relatively focused sphere of influence, roughly equal to the width of the receiver dipole, penetrating vertically downward from surface to great depths. The resistivity is among the most variable of all geophysical parameters, with a range exceeding 106. Because most minerals are fundamentally insulators, with the exception of massive accumulations of metallic and submetallic ores (electronic conductors) which are rare occurrences, the resistivity of rocks depends primarily on their porosity , permeability and particularly the salinity of fluids contained (ionic conduction), according to Archie’s Law. In contrast, the chargeability responds to the presence of polarizable minerals (metals, submetallic sulphides and oxides, and graphite), in amounts as minute as parts per hundred. Both the quantity of individual chargeable grains present, and their distribution with in subsurface current flow paths are significant in controlling the level of response. The relationship of chargeability to metallic content is straightforward, and the influence of mineral distribution can be understood in geologic terms by considering two similar, hypothetical volumes of rock in which fractures constitute the primary current flow paths. In one, sulphides occur predominantly along fracture surfaces. In the second , the same volume percent of sulphides are disseminated throughout the rock. The second example will, in general, have significantly lower intrinsic chargeability.

Because most minerals are fundamentally insulators, with the exception of massive accumulations of metallic and submetallic ores (electronic conductors) which are rare occurrences, the resistivity of rocks depends primarily on their porosity , permeability and particularly the salinity of fluids contained (ionic conduction), according to Archie’s Law. In contrast, the chargeability responds to the presence of polarizable minerals (metals, submetallic sulphides and oxides, and graphite), in amounts as minute as parts per hundred. Both the quantity of individual chargeable grains present, and their distribution with in subsurface current flow paths are significant in controlling the level of response. The relationship of chargeability to metallic content is straightforward, and the influence of mineral distribution can be understood in geologic terms by considering two similar, hypothetical volumes of rock in which fractures constitute the primary current flow paths. In one, sulphides occur predominantly along fracture surfaces. In the second , the same volume percent of sulphides are disseminated throughout the rock. The second example will, in general, have significantly lower intrinsic chargeability.

POLE-DIPOLE TDIP SURVEY

The collected data sets are reduced, using IP6 receiver, to apparent resistivity, total chargeability and metal factor as explained in the following figures and equations: Using the following diagram (Fig. C3) for the electrode configuration and nomenclature:6

DIPOLE-POLE ARRAY

Figure C3: Pole-Dipole Electrode Array

the apparent resistivity is given by:

metres-ohm I

VP a 1nn= 2a

where: “a” is the MN dipole spacing (metres) “n” is the separation parameter between C1 and P1P2 “VP” is the primary voltage measured between P1P2 (volts)

“I” is the output current between C1C2 (amperes) The Total Chargeability calculations are the same as the Gradient arrays as explained above:

The sets are then ready for plotting, profiling using the Geosoft SushiTM program. The Apparent Resistivity, Total Chargeability and Metal Factor (IP/Resistivity*1000) results of the Pole-Dipole surveys are presented in pseudo section format. All resistivities are in �-metres and chargeabilities in mV/V.
