SUMMARY The East West Resource Corporation and Maple Minerals Corporation jOint venture holds 304 claim units in 23 claims in the Ames, Burchell, Crayfish Lake, Moss, and Tilly Townships, within the Shebandowan greenstone tElt, about 70 miles/ 112 km west of Thunder Bay, Ontario. The claims are recorded 50% to each company. This report deals with the recent helicopter bome time domain EM and magnetic geophysical survey over part of the claims group to explore for extensions of mineralized showings on surface.

On May 20th to June 7th, 2005, Geotech Ltd flew the Pele area with the helicopter-bome time domain

electromagnetic/magnetic survey system. This survey was intended to outline electromagnetic conductors and to obtain detail magnetic information for the purpose of outlining the subsurface geology. Results of the survey are appended as maps. The survey covered a wider area including the Pele Gold Aberdeen property, which has been optioned by the Companies. The portion of the SUM:lY relevant to this report is measured to be 82.49 km.

INTRODUCTION

East West Resource Corporation together with Maple Minerals Corporation have been directing their attention to greenstone belts in addition to interest in ultramafic intrusives. The Obadinaw Group claims are in the Shebandowan greenstone belt in the Wawa subprovince. The Archean age Superior Province includes several greenstone belts with iron formations and sulphide occummces, many with economic basemetal mineralization. Although the greenstone belts have been subject to exploration for many years, newer geophysical techniques have improved the discrimination of conductive features as well as providing a better depth penetration. Helicopter borne geophysical surveys have been used for many years, but they have been based on frequency domain systems which have limited depth penetration, although generally resolution of near surface features has been good. The move to time domain electromagnetic systems began in the 1960's with the Barringer Research INPUT® system. INPUT® improved depth penetration, although resolution was less. Several time domain systems have been developed since, among them the Fugro (formerly Geoterrex) Megatem® system with high power and very good depth penetration. Recently Geotech Ltd has developed and tested the helicopter borne Time Domain Electromagnetic (TDEM) system. Test flights by Megatem® and TDEM have shown comparable depth penetrations but better lateral resolution for the latter. The Companies decided to use the TDEM system for a detail look at several areas of the Shebandowan greenstone belt and the present claims group in particular.

GEOLOGY OF THE CLAIM GROUP AND AREA

The Obadinaw claims are in the Shebandowan greenstone belt of the Wawa Subprovince of the Superior Province. The age is Archean. The Shebandowan greenstone belt is arcuate in shape reflecting the curvature of the QueUco - Shebandowan greenstone belt boundary, approximately WSW - ENE as shown by the magnetic trends. The Shebandowan greenstone belt is subdivided into the Burchell and Greenwater assemblages. with a third suite of rocks. the Shebandowan assemblage. consisting of sedimentary and volcanic rocks which overlie unconformably the Burchell - Greenwater boundary. locally straddling it. The Burchell assemblage is divided into three cycles, with cycle 1 intruded by the Shebandowan Lake intrusion. The lower part of cycle 1 comprises massive basalt flows locally altered to chlorite schist. Pillow lava underlies the dacite and rhyolithic units in the upper parts of the cycle. Near the base of this cycle are tabular. serpentinized, peridotite units that contain copper - nickel mineralization. Cycle 1 contains the most extensive basic intrusions in the greenstone belt. Cycle 2 also contains numerous mafic intrusions. but also distinguished by a thick unit of rhyolite to dacite, which extends along the northem part of the belt. The main mass of this felsic unit located in and south of the Burchell area is displaced and separated from the more tuffaceous eastern part by right-handed transcurrent movement on the Crayfish Creek fault. (The geology information has been abstracted from "Geology of Ontario; OGS Special Volume 4. Pt1. 1991.) Further geological information in: Ontario Geological Survey. 1991. Airbome electromagnetic and total intensity magnetic survey, Shebandowan Area; Ontario Geological Survey. Maps 81571. 81572. 81573. 81588. and 81589, scale 1 :20,000. The property covers an eight km long nort~east extension of a series of shear zones that continue from the La Rose gold occurrence in Moss Township. The Obadinaw claim group covers sheared and altered metasediments as well as felsic intrusions that are similar to the rocks hosting a new gold discovery on the La Rose property. The property also covers a 4-5 km section of the Boundary Fault which parallels the structure associated with the La Rose showing and is adjacent to structures associated with gold zones at the Aberdeen Mine where five zones of gold mineralization occur (information from East West Resource Corp).

HELICOPTER TIME DOMAIN ELECTROMAGNETIC - MAGNETIC SURVEY

On May 20th to June 1h, 2005, a helicopter borne geophysical survey was flown over an area covering

Moss and adjacent Townships. Navigation was by GPS and radar altimetry. The flying height was maintained at 85 m above ground, with the VTEM sensor at 30 m above ground and 70 m above ground forthe magnetic sensor, and aircraft velocity was nominally 80 kmlhour. In total 16'76 line-km were contracted to be flown. The low altitude of the sensor and relatively slow speed of he aircraft, coupled with the superior depth penetration and sensitivity of a time domain electromagnetic systnm has produced survey results where closely located conductors have been discriminated. This is important in areas where graphitic conductors run alongside sulphide conductors, whether iron formations or economic sulphides, thus aiding in mapping the geology and drilling. Test flights over known mineral occurrences have compared favourably with results of fixed-wing time domain systems, where the much higher altitude has caused adjacent conductors to merge. The flight line direction was northwest-southeast with a nominal 100 m separation. The data has been plotted as total field magnetic contours and stacked EM profiles for the Obadinaw claims. Claim outlines have been shown on the maps. Not all of the claims were covered. A synopsis of the Geotech specifications is appended with further details of the operation and equipment.

Discussion of Results The magnetic and EM conductor trends are nearly SW to NE, following magnetiC trends. Strong rmgnetic anomalies are present on claim 3007116 and along the northern edge of the survey coverage, in the easternmost part of the survey area with flanking EM conductors. Most of the electromagnetic anomalies are of low amplitude on both the early and late time windows. The airborne EM results are presented as prOfiles, with claims, at a scale of 1 :20,000, the scale at which the data was delivered by Geotech Ltd. The detail magnetic survey is presented as a contour map for total magnetiC intenSity at a scale of 1 :20,000. The claims were digitized from Government claim maps. In order to provide a quick view of the data, the maps have also been reduced to a scale of 1 :30,000 and appended to the report.

CONCLUSIONS AND RECOMMENDATIONS

Most of the EM responses have a very low amplitude. and are best viewed on detail profiles on individual lines where they can be enhanced for better analysis. It may be useful to have VLF-EM or induced polarization to further probe conductors. which appear in the airborne work but have no surface evidence. Pseudosection calculations on the VlF-EM data may separate close conductors not already evident in the helicopter survey as well as depth and depth extent within the range of VlF-EM detectability. This would be followed by induced polarization where deemed useful. prior to drilling.

The airborne geophysical survey using the Geotech helicopter borne VTEM system has produced a number of results in the form of conductors. Some of these conductors may be eliminated through surface mapping as being either graphitic formations or non-economic sulphides. There will remain a number of features which can only be analyzed by drilling. particularly those at depth. The airborne survey was using a GPS based navigation system with UTM coordinates at NAO 83. The locations are therefore comparable with coordinates obtained by ground surveys. the use of which can thus be much reduced.

1. INTRODUCTION

1.1 General Considerations

lbese services are the result of the Agreement made on April 281h

, 2005 between Geotech Limited and East West Resource Corporation, to perform a helicopter­borne geophysical survey over two (2) blocks near Kashabowie, Ontario, Canada.

16761ine-km of geophysical data were acquired during the survey.

Mr. Robert Middleton acted on behalf of East West Resource Corporation during data acquisition and processing phases of this project.

Survey blocks are as shown in Appendix A. The crew was based in Kashabowie, Ontario for the acquisition phase of the survey, as shown in Section 2 of this report.

The helicopter was based at the Hotel parking lot in Kashabowie for the duration .h

of the survey. Survey flying was completed by June 7 ,2005. Preliminary data processing was carried out daily during the acquisition phase of the project. Final data presentation and data archiving was completed in the Aurora office of Geotech Limited by July, 2005.

1.2. SUlVey and System Specifications

Survey blocks were flown at nominal traverse line spacing of 100 metres and 200 metres. Tie lines were flown perpendicular to traverse lines.

Where possible, the helicopter maintained a mean terrain clearance of 85 metres, which translated into an average height of 30 meters above ground for the bird­mounted VTEM system and 70 meters above ground for the magnetic sensor.

The two survey blocks were flown using an Astar B+ helicopter, registration C­GCYE, operated by Expedition Helicopters Inc. Details of the survey specifications are found in Section 2 of this report.

1.3. Data Processing and Final Products

Data compilation and processing were carried out by the application of Geosoft OASIS Montaj and programs proprietary to Geotech Limited. Maps, grids and databases of final products were presented to East West Resource Corporation.

The survey report describes the procedures for data acquisition, processing, final image presentation and the specifications for the digital data set.

1.4. Topographic Relief

The survey blocks are located approximately 15 kilometres south-west of Kashabowie.

Topographically, the blocks exhibit a complex relief, with elevation range from 400 metres to 550 metres above sea level. The blocks intersect several rivers and lakes. Wetlands are also observed. Due to building areas surrounding Burchell Lake, the flight path was not properly cover as planned. The properties have road access.

2. DATA ACQUISITION 2.30780 2.1. Survey Area

Survey blocks and general flight specifications are as follows:

Table I - Survey blocks

2.2. Survey Operations

Line L4010 - 6230 T6900 - 6960

T7900 - 7930

Survey operations were based in Kashabowie, Ontario for the acquisition phase of the survey. The crew was housed at Kashabowie Lodging for the survey period .

2.3. Flight Specifications

The nominal EM sensor terrain clearance was 30 m (EM bird height above ground, i.e. helicopter is maintained 85 m above ground). Nominal survey speed was 80 kmlhour. The data recording rates of the data acquisition was 0.1 second for electromagnetics and magnetometer, 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 GPS receiver and data acquisition system, which reports GPS co-ordinates as latitudeliongitude and directs the pilot over a pre­programmed 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.

2.4. Aircraft and Equipment

2.4.1. SurveyAircraft

An Astar B+ helicopter, registration C-GCYE - owned and operated by Expedition Helicopters Inc. was used for the survey. Installation of the geophysical and ancillary equipment was carried out by Geotech Ltd.

2.4.2. Electromagnetic System

The electromagnetic system was a Geotech Time Domain EM (VTEM) system. The layout is as indicated in Figure 1 below.

Receiver and transmitter coils were concentric and Z-direction oriented. The EM bird was towed 45 m below the helicopter. Transmitter coil diameter was 26 metres, the number of turns was 4. Transmitter pulse repetition rate was 30 Hz. Peak current was 200 Amp. Receiver coil diameter was 1.1 metre, the number of turns was 100. Duty cycle was 40%. Peak dipole moment was 424,800 NIA. Wave form - trapezoid. Twenty-five measurement gates were used in the range from 130 I!S to 6340 I!s. The transmitter wave form and the receiver decay recording scheme is shown diagrammatically in Figure 2. Recording sampling rate was 10 samples per second.

2.4.3. Airborne magnetometer

The magnetic sensor utilized for the survey was a Geometrics optically pumped cesium vapor magnetic field sensor, mounted in a separate bird towed 15 m below the helicopter. 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 nanoTeslas to the data acquisition system via the RS-232 port.

2.4.4. AncillarySystems

2.4.4.1. Radar Altimeter

A Terra TRA 3000/TRI 30 radar altimeter was used to record terrain clearance. The antenna was mounted beneath the bubble of the helicopter cockpit.

2.4.4.2. GPS Navigation System

The navigation system used was a Geotech PC based navigation system utilizing a NovAtel's W AAS enable OEM4-G2-3151 W GPS receiver, Geotech navigate software, a full screen display with controls in front of the pilot to direct the flight and an Nov Atel GPS antenna mounted on the helicopter tail.

The co-ordinates ofthe block were set-up prior to the survey and the information was fed into the airborne navigation system.

2.4.4.3. 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. Contents and update rates were as follows:

DATA TYPE SAMPLING I

TDEM 0.1 sec

Magnetometer 0.1 sec

GPS Position 0.2 sec

RadarAltimeter 0.2 sec

Table 3 - Sampling Rates

2.4.5. Base Station

A combine magnetometer/GPS base station was utilized on this project. A Geometries Cesium vapour magnetometer was used as a magnetic sensor with a sensitivity of 0.00 1 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 in the motel where the crew was housed in Kashabowie, away from electric transmission lines and moving ferrous objects such as motor vehicles.

The magnetometer base station's data was backed-up to the data processing computer at the end of each survey day.

4. DATA PROCESSING AND PRESENTATION

4.1. Flight Path

The flight path, recorded by the acquisition program as WGS 84 latitude/longitude, was converted into the UTM 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 eastings (x) and UTM northings (y).

7

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 20 metres. This filter is a symmetrical 1 sec linear filter.

The results are presented as stacked profiles of EM voltages for the gate times, in logarithmic scale.

4.2.1 Resistivity - Depth sections

Lines were subjected to Resistivity - Depth calculation using Geotech proprietary software. Time domain geophysical data from 0.13 milisecond to 6.34 milisecond were used in the calculation.

Two hundred fifty six (256) traverse lines were presented as Resistivity -Depth sections.

4.3. 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 aero magnetic 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 the traverse lines. A micro-levelling procedure is then applied. This technique is designed to remove persistent low-amplitude components of flight-line noise remaining after tie line levelling.

The corrected magnetic line data from the survey 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 0.2 cm at the mapping scale. The Minimum Curvature algorithm was used to interpolate values onto a rectangular regular spaced grid.

5. GEOPHYSICAL INTERPRETATION

5.1. Pe/e block

The Pele block is composed of numerous tabular, "'plate-like" conductors with moderate to strong conductance. The conductors are grouped in conductive trends but individually appear as numerous interrupted segments with varying strike lengths (200 to 600 metres in length).

The conductive trend is associated with the northwest side of a mafic complex that trends north east through the map area. The EM anomalies are coincident with or flank the second derivative magnetic anomalies.

The conductive trend to the north does not have any coincident magnetic response. The EM anomaly to the south lies on the south flank of the second derivative magnetic anomaly.

6.1. Survey Report

The survey report describes the data acquisition, processing, and final presentation of the survey results.

6.2. Maps

Final maps were produced at a scale of 1 :20,000. The coordinate/projection system used was WGS84, UTM zone 15 north. For reference the latitude and longitude are also noted on the maps. All maps show the flight path trace and topographic base data.

The following maps are presented to East West Resource Corporation on paper as results of the helicopter-borne geophysical survey carried out over the two blocks.

• Total Magnetic Field contours and colour image • Logarithmic scale Time Gates 0.22 - 6.34 profiles

7. CONCLUSIONS

A time domain electromagnetic helicopter-borne geophysical survey has been completed over two survey blocks near Kashabowie, Ontario, Canada.

2

The total area coverage is 188 km. Total survey lim~ coverage is 1676 line kilometres. The principal sensors included a Time Domain EM system and a magnetometer. Results have been presented as colour contour maps and stacked profiles at a scale of 1 :20,000.

Final data processing at the office of Geotech Limit(~d in Aurora, Ontario was carried out under the supervision of Andrei Bagrianski, Data Processing Manager.

Geophysical interpretation was made by Roger Barlow, Geophysicist.

A number of EM anomaly groupings were identified. Ground follow-up of those anomalies should be carried out if favourably supported by other geoscientific data.
