Objectives:

1. Using IP\Resistivity, to map bulk conductivity and chargeabilitydistributions in order to locate potential base-metal sulphide concentrations associated with diabase dykes for the purposes of drill targeting, and to assist in general geologic mapping of lithology, structure and alteration.

2. The n^-6 Dipole-dipole array was chosen based on its simplicity, cross- sectional imaging capabilities and shallow to moderate depth penetration characteristics. The gradient profiling technique was later chosen due to better signal-to-noise, improved survey economics, and superior lateral resolution and depth penetration.

4.1. OVERVIEW

The following discussion summarizes the results of the Gradient/ Dipole-Dipole TDIP/Resistivity surveys over the Hess Grid, undertaken by Matrix GeoTechnologies Ltd. The exploration target consists of offset dyke deposit, with the mineralization occurring as disseminated to massive sulphides.

The present geophysical interpretation makes use of both the Resistivity and Time Domain Induced Polarization surveyed parameters, but puts particular emphasis on the chargeability parameter, due to its ability to detect and discern sulphide mineralization ranging from disseminate to massive concentrations. Furthermore, given its property wide coverage, the gradient array survey results are relied upon as a bulk conductivity/chargeability mapping tool - with the more limited dipole-dipole coverage used to better define and detail the cross-sectional nature of the TDIP responses at depth. Of note, regarding the differences in information provided by the dipole-dipole and gradient arrays, in contrast to the dipole-dipole array data, which are more localized in their application, the nature of the information obtained, and the depth control, the present gradient surveys map are more regional in character - owing to the broader and stationary Tx array used and the resulting single stationary field distribution for the entire survey. The large transmit dipole employed provides significant depth of investigation in the central region of the grid and the 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 investigation depths approaching 250 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- this also contrast the dipole-dipole results, which are best considered in cross-sectional representation format. Furthermore, the gradient array anomaly patterns are essentially subvertical (i.e. without complex, asymmetric pant-leg shapes, as in dpdp), and can be visualized in plan in the same manner as magnetic 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 dipole-dipole - greater discrepancies can also occur with dipole-dipole, owing to the asymmetric array geometry, which tends to bias anomalies towards the infinity pole.

The geophysical interpretation plan presents the interpreted anomaly axes, highlighting the strength and resistivity association of the IP axes to their source/alteration type:

a) High resistivity IP axes, related to either disseminated sulphides or magnetite possibly associated with quartz-carbonate alteration or, alternatively, more felsic/less porous geology and/or bedrock/overburden topographic effects;

b) Nil (flat) resistivity and contact-type IP axes likely correspond to possibly more weakly- altered and/or thin/buried sulphide zones and/or mineralization along geologic contacts, or magnetite/hematite; and

c) Low (conductive) resistivity IP axes representing the key target signature relating to possible massive to stringer sulphides or, alternatively, faulted or clay-altered disseminated sulphides magnetite/hematite.

Clearly, while all anomaly types (high p / low p / nil p), could potentially represent equally valid exploration targets, the high resistivity/high chargeability association best represents the key geophysical target signature, based on the geologic model.

QS160-Februafy, 2001 11

The chargeability axes identified on the anomaly axis map have been: a) categorized according to their strength (weak, moderate, strong, very strong) using symbols, and b) classified according to their resistivity association (high p, nil p/contact-type, low p) using colored axes. The line-to-line correlation of anomalies into axes is based primarily on the resistivity association (i.e. resistive and conductive anomalies never aligned along the same axis due to likely dissimilar mineralogy l a lteration l origin) - thereby providing some measure of geologic/geophysical control to the interpretation. Note that, due to the relative insensitivity of Gradient to depth of burial, target depths have not been determined for the anomalies of interest.

In order to better highlight the close relationship between the IP (sulphide magnetite) and Resistivity (lithology, structure, alteration), the areas of geophysical interest have been identified on the interpretation plan, using variable cross-hatching styles: a) contrasting zones of resistivity, highlighting potential geological contacts, alteration zones and fault-fracture structure, b) zones of high chargeability, outlining potential regions of increased sulphide mineralization. In addition, fault structures have also been interpreted based on evidence from the TDIP results, generally represented by lower resistivity and lower chargeability.

HESS GRID

GRADIENT TDIP SURVEY RESULTS

The following represent the geophysical interpretation of the gradient survey over the Hess Grid, making use of Resistivity and TDIP surveyed parameters, particularly emphasis on the chargeability parameter, due to its ability to detect and discern sulphide mineralization ranging from disseminate to massive concentrations. Furthermore, given its property wide coverage, the gradient array survey results are relied upon as a bulk conductivity/chargeability mapping tool.

The total chargeability and apparent resistivity show that the Hess Grid is characterized by moderate to strong IP responses, ranging from 10 mV/V to 14 mV/V. This is associated with high/nil resistivity, which form NE-SW bands following - suggesting possible disseminated to semi-massive sulphides. Hence, in addition to more favorable, in terms of strength of chargeability the nil/high resistivity association of the highest priority targets also best fit the geologic target model, likely representing the mineralization along an offset dyke and/or contact deposit type. On the other hand, low resistivity/strong to moderate IP responses are observed, suggesting possible presence of massive mineralization in the property, implying the property is characterized by two type of geophysical targets.

More moderate chargeabilities associated with similar resistivity either indicate more deeply buried mineralization or weaker sulphide/magnetite content.

The gradient chargeability responses at Hess Grid a re characterized by the broad range in strength, varying between weak to very strong (1.0 to 19.4 mV/V) but generally falling in the weak category (avg. 6.0 mV/V) - consistent with non-polarizable geological units and/or moderate overburden cover. The total chargeability shows a well-defined chargeability contact in the north, associated with resistivity contact, likely defining the geological contact between more polarizable units to the north, consistent to intrusives and less polarizable metasediments. The strong measured chargeabilities observed in the central part of the grid are consistent to massive sulphides, when conductive, otherwise important concentration of disseminated sulphides and/or magnetite (when magnetic), particularly when high resistivity. The most important IP axes are generally strike extensive ^200 m), displaying generally strong responses, either reflecting high in concentration or shallow depth of burial along the strike. In addition to, the high IP features display wide, oval shape, occurring along high/low resistivity contacts, suggesting contact deposit types, likely with semi-massive to massive mineralization in the center rimmed by disseminated sulphides.

QS160-February, 2001 11

The apparent resistivities display a wide range, varying between 195 ohm-m to 77.5 k ohm-m (avg. 19.6k Q-m), indicative of a mixed low porosity bedrock at depth - with the average consistent with outcropped or shallow buried volcanics. Generally, the apparent resistivity plan map shows a more complicated distribution of the geological units, with higher resistivity units in the north and grid center, likely representing intrusives or metavolcanics. The very high resistivity values possi bly reflect the outcropping and/or shallow occurrence. The conductive units likely represent me- '^sediments and/or deep overburden, following the same trends as weak chargeability geology. As n roviously mentioned, the high/low resistivity contact observed in the north, approximately follow-

i q the TL2+OOS, likely represents the geological contact between volcanics and the more porousnetasedimentary units.

Nearly all the strong anomalies present good geophysical targets, especially those exhibiting conductive and nil/contact type resistivity association represent the primary geophysical target - ins list presented in Table VII is designed to help direct follow-up and possibly also DDH-testing into the best portion of the major axes.

Hess Grid

The Hess Grid exhibits moderate to strong IP anomalies in plan, dominant high/nil/contact re sistivity association, suggest the possibility of disseminated mineralization. In addition to, low re sistivity/strong chargeability present in the grid likely are related with heavily disseminated to mas sive. The geophysical axes of significance predominate the central part of the survey area. The gradient data shows a NE-SE band of high resistivity/weak to moderate chargeability likely repre senting disseminated volcanics or deeper zones of interest.

In response to the survey objectives, three (3) high priority targets have been identified in the central part of the grid area, which are of significant strength to warrant geophysical follow-up prior DDH-drilling program. For the most part, these also feature high bulk resistivities, consistent with disseminated sulphide mineralization. As many as two (2) lower priority targets are also defined, which either feature weaker chargeability - ground geophysical follow-up is strongly recommended prior DDH-drilling program.

We recommend the interpreted anomalous chargeability zones delineated by the combination of gradient and dipole-dipole surveys, represented as. Quantitative Sections, to be examined by drill-testing. Also, ground magnetic survey can provide useful information regarding the geological structures and the delineation of offset dyke in the property.

Further evaluation of the geophysical results in combination .with existing geoscientific data is also recommended. Drill testing the interpreted geophysical targets described above has been recommended according to target specifications defined based primarily on the combined inter pretation of gradient and dipole-dipole cross-sectional coverage, finalized in Quantitative Sec tions.

The chargeability axes display a variety of strengths and resistivity associations, such that, based on the gradient survey alone, all the most significant anomalies represent equally good tar gets, particularly the conductors - possibly differing only in their type-alteration. Particular atten tion should be given to the probable type of mineralization and alteration indicated by the resistivity association (i.e. high p s silicic, nil p = weak silicic/argillic, low p = argillic or stringer-to-massive). Additional comparisons against recommended ground magnetics could provide insight on the source mineralogy of many IP targets, i.e. magnetic = probable pyrrhotite or magnetite iron forma tion. The continued use of combined geophysical techniques, such as magnetics and TDIP, should prove useful in fully determining physical property distributions and mineral composition throughout the property.

Clearly, we recommend that the ground surveys be extended, as the strongest IP anomalies remain open, and additional geophysical follow-up are strongly recommended in the grids with gra dient survey coverage only, in order to obtain information regarding the depth extension of the geological structures and/or mineralization. Also, as previously mentioned additional ground mag netics survey is recommended helping to define the non-magnetic targets and/or structural geol ogy.

'EORFTICAL BASIS AND SURVEY PROCEDURES

GRADIENT INDUCED POLARIZATION SURVEY

The Gradient Array measurements are unique in that fiey best represent a bulk average of the sur- unding physical properties within a relatively focused sphere of influence, roughly equal to the width of the neiver dipole, penetrating vertically downward from surface t j great depths. These depth of penetration*d lateral resolution characteristics are typically presented in plan.

The resistivity is among the most variable of all geophysical parameters, with a range exceeding f. Because most minerals are fundamentally insulators, with the exception of massive accumulations of etallic and submetallic ores (electronic conductors) which are rare occurrences, the resistivity of rocks de- irids primarily on their porosity , permeability and particularly the salinity of fluids contained (ionic conduc- n), according to Archie's Law. In contrast, the chargeability responds to the presence of polarizeable min- iis (metals, submetallic sulphides and oxides, and graphite), in amounts as minute as parts per hundred. 1 1 the quantity of individual chargeable grains present, and their distribution with in subsurface current•" paths are significant in controlling the level of response. The relationship of chargeability to metallic itent is straightforward, and the influence of mineral distribution can be understood in geologic terms by nsidering two similar, hypothetical volumes of rock in which fractures constitute the primary current flow iths In one, sulphides occur predominantly along fracture surfaces. In t!ie second , the same volume per- rit of sulphides are disseminated throughout the rock. The second example will, in general, have signifi- r tly lowor intrinsic chargeability.
