SUMMARY

A helicopter-borne magnetic and electromagnetic survey was flown between October 29 and November 4, 2002 on three claim groups of Aurora Platinum Corporation (Fishtrap Lake, Canopener-Rowlandson, and Sheridan Lake) in northwestern Ontario. This report describes all three surveyed areas but only discusses the results of Fishtrap Lake survey for the purposes of filing assessment work credits as required by the Ontario Ministry of Northern Development and Mines.

The Fishtrap Lake property is located approximately 300 km and 500 km northeast of Pickle Lake and Thunder Bay, respectively, in northwestern Ontario. It is centred at latitude 52 022'N and longitude 86024'W and may be found on NTS map 43D/8. The property accessed by major and subsidiary highways from Thunder Bay to Pickle Lake and from there by fixed-wing float and ski-equipped aircrafts and helicopter to the Fishtrap Lake property.

The Fishtrap property consists of 49 unpatented mining claims (760 units, 12,160 ha) located within BMA 523 862 Area (G-5125) of Porcupine Mining Division in northwestern Ontario. Aurora Platinum Corp. owns 10007o interest in all the claims on the property. Exploration work that consisted of a helicopter-borne magnetic and electromagnetic survey in the 2002 covers all the claims as shown on the Flight Path Map (Plate 1).

The geophysical sensors on the survey included Aeroquest's IMPULSE six channel frequency time domain helicopter electromagnetic system and a high sensitivity cesium vapour magnetometer. Ancillary equipment included a GPS navigation system with GPS base station, radar altimetre, video recorder and a base station magnetometer. The survey was flown in northeast and southwest direction at 125m-150m line spacing with EM bird terrain clearance of approximately 30 metres. The magnetometer sensor was mounted in the EM bird 33.5 metres below the helicopter. The survey speed was 120 km/hr or 70 knots and geophysical reading was acquired roughly 3.3 metres/second along flight track.

The survey data is presented as maps of the total magnetic intensity contours with EM anomalies, total magnetic intensity contours with EM anomalies, magnetic vertical gradient contours with EM anomalies, low, mid and high frequency EM offset proof of the magnetics, apparent conductance, EM B-field X-coil channel 10 amplitude and EM anomalies at l :20,000 scale. The main purpose of the surveys was two fold: 1) to acquire information with respect to the litho-structural framework on the basis of bedrock magnetic responses; and 2) to identify areas of precious and base metal sulphides on the basis of bedrock conductive and magnetic responses. All significant EM anomalies are listed in Appendix 3.

REPORT ON A HELICOPTER-BORNEMAGNETIC AND ELECTROMAGNETIC SURVEY

AEM Project Landsdowne House Area, Ontario

1. INTRODUCTION

This report describes a helicopter-borne geophysical survey carried out on behalf of Aurora Platinum Corp. on three different claim groups (Fishtrap Lake, Canopener-Rowlandson, and Sheridan Lake) of the AEM Project near Landsdowne House, Ontario.

The AEM project and the target mineralisation is described as follows on the company website: "Aurora has been actively exploring the AEM project and has acquired a number of new properties as a consequence of this work. Two additional layered mafic-ultramafic bodies have been discovered and ground in the area has been acquired. Copper-nickel mineralization has been found associated with both of these bodies. A number of gold properties have been acquired in the project area. Typical Archean vein-type gold mineralization was discovered associated with a prominent regional shear structure."

The principal geophysical sensors on the survey included AeroQuest's exclusive IMPULSE six channel frequency time domain helicopter electromagnetic system and a high sensitivity cesium vapour magnetometer. Ancillary equipment included a GPS navigation system with GPS base station, radar altimeter, video recorder, and a base station magnetometer.

The survey was flown at 125-150 metre line spacing. The flight direction was different for each block and was optimised for the local geology. Appendix l lists the UTM corner co-ordinates for the survey block. The total line kilometres flown was 2413.8 km including tielines. The survey flying took place between October 29 and November 4, 2002 and was completed with nineteen survey flights.

This report describes the survey, the data processing and presentation. Bedrock EM anomalies were picked and graded according to the interpreted conductance (conductivity-thickness) based on a vertical thin sheet model response to mid frequency coaxial coil configuration. A higher conductance indicates a better conductor. A list of picked EM anomalies may be found in the appendix.

If the starts and ends of each line outside the nominal survey boundary are excluded, i.e. clipped or windowed, the line kilometres falls to 2269.9 km. Nominal EM bird terrain clearance was 30+ metres (100+ ft). The magnetometer sensor was mounted in the EM bird 33.5 metres (110 ft) below the helicopter. Nominal survey speed was 120 km/hr or 70 knots. Scan rates for data acquisition was 30Hz (30 times per second) for the electromagnetics, lOHz (10 times per second) for the magnetometer, and altimeter and l Hz (l time per second) for the GPS determined position. This translates to a geophysical reading about every 3.3 metres along flight track but ground speed does vary depending on the strength of the prevailing wind and topographic relief.

Navigation was assisted by a OPS receiver and the AG-NAV2 flight path guidance system which reports OPS co-ordinates as WGS-84 latitude/longitude and directs the pilot over a pre-programmed survey grid. The x-y-z position of the aircraft, as reported by the GPS, is recorded at one second intervals.

The operator was responsible for ensuring the instrument was properly warmed up prior to departure and that the instruments operated property throughout the flight. He also maintained a detailed flight log during the survey noting the times of the flight as well as any unusual geophysical or topographic features. High altitude zero calibration lines were flown at regular intervals during the flight.

The integrated magnetics and GPS base station was located at the camp. The mag sensor and GPS antenna were installed on poles located metres away from any potential magnetic interference or any obstructions to the GPS signals. The magnetics data was logged internally in the magnetometer and transferred to the field processing station daily.

On return of the aircrew to the helicopter base, the PDAS-1000 acquisition system survey data was transferred to Zip Disk and then downloaded onto the field data processing work station. In-field processing included data archiving and flight path reconstruction, quality control checks and preliminary processing of the EM and magnetic data. Generation of a Geosoft GOB database and production of preliminary EM, magnetic contour, and flight path maps were done on the field data processing computer. Any data exhibiting either poor flight control or technical problems with the control or geophysical instrumentation or acquisition systems were rejected. In those event the lines were reflown.

4. AIRCRAFT AND EQUIPMENT

4.1 Aircraft

A Bell Textron 206L1 LongRanger helicopter - registration C-FLRU - owned and operated by Helicopter Transport Services (Canada) Inc., Carp, Ontario. Installation of the geophysical and ancillary equipment was carried out by AeroQuest Limited at the Pickle Lake Airport. The survey aircraft was flown at a nominal terrain clearance of 200-250 ft (61-76 m). Mean terrain clearance was 210 feet.

4.2 Electromagnetic System

The electromagnetic system employed was an AeroQuest IMPULSE 6 channel frequency domain towed bird system. This wideband frequency-domain system utilises a single computer-controlled, high-output transmitter driver to power single horizontal coplanar and vertical coaxial transmitter coils, producing a total of six frequencies (three in each coil orientation). The common coil approach used in IMPULSE has the potential to minimise system baseline drift and the often seen disparate performance of the many superimposed coil sets found in traditional frequency-domain systems. The IMPULSE system uses a larger diameter tubular coil platform (30" as opposed to the traditional 20") which permits the system to generate larger dipole moments, thereby resulting in an improved signal-to-noise ratio.

Calibration of the IMPULSE sytem conforms to the 4: l convention for coplanar to coaxial response. Furthermore, although the coil separations of the coplanar and coaxial coils are 5.8 and 6.3 metres respectively, the calibration is configured to give the equivalent response of a 6.5 metre coil separation system.

Calibration of the system is conducted with an external coil which when placed at a certain distance from the bird gives rise to an anomaly of known amplitude. The gain of the system is then adjusted such that the measured response in both the analog and digital records matches the known quantity. The calibration and phasing were checked with the external coils and ferrite bar respectively in Pickle Lake prior to the start of the survey to ensure the system was property set-up. Further checking of the system gain is carried out with an internal "Q-coil" mounted in the bird itself. The operator will close the internal coils at regular intervals, say the start, mid point, and end of each flight, which will generate an anomaly which should show a consistent amplitude. The data from both the external and the internal regular in-flight checks are included in the survey archive database.

4.3 Magnetometer

The AeroQuest airborne survey system employed the Geometrics G-822A cesium vapour magnetometer sensor installed in the EM bird, 39 metres below the helicopter. The sensitivity of the magnetometer is 0.001 nanoTesla at a 0.1 second sampling rate. The nominal ground clearance of the magnetometer bird was 30 metres (100 ft.).


Aurora Platinum Corp. - AFM Project

4.4 Ancillary Systems

Magnetometer and GPS Base Station

A GPS and magnetometer base station was set up at the camp to monitor the static position GPS errors to permit differential post-processing and to record the diurnal variations of the earth's magnetic field. The GPS receiver/signal processor was attached to a dedicated laptop computer, with Picodas logging software installed, for purposes of instrument control and/or data display and recording.

The magnetometer was a GEM GSM-19 overhauser magnetometer configured to measure at l second intervals. The sensor was placed on a tripod away from potential noise sources. The clock of the base station was synchronised with UTC time as output by the GPS receiver (in order to allow correlation with the airborne data). Digital recording resolution was 0.01 nT and the data was stored internally in the magnetometer. At the end of each survey day the data was dumped to the field processing computer and then merged with the general database.

The GPS base station employed a Leica MX9212-12 channel GPS receiver with external antenna. The static location of the antenna was recorded at one second intervals to permit differential corrections to be made to the helicopter GPS recorded flight path if required.

Radar Altimeter

A Terra TRA 3000/TRI-40 radar altimeter was used to record terrain clearance. The antenna was mounted on the inside of the helicopter on the bubble in front of the front passenger seat. The recorded data represented height of the antenna, i.e. helicopter, above the ground. The Terra altimeter has an altitude accuracy of +I- 5 feet

During the survey, a calibration check of the altimeter was performed at various fixed altitudes (determined by the aircraft barometric altimeter as well as the tow cable) above the ground to establish the correct relationship between the digital record, the pilot indicator and the actual terrain clearance. The digital record was corrected for any departures from the true height above ground.

Video Tracking and Recording System

A high resolution colour video camera was used to record the helicopter ground flight path along the survey lines. The video, in VHS format, is digitally annotated with GPS position and time and can be used to verify ground positioning information and cultural causes of anomalous geophysical data.


Aurora Platinum Corp. - AEMProject

GPS Navigation System

The navigation system consisted of an Ag-Nav Inc. AG-NAV2 GPS navigation system comprising a PC based acquisition system, navigation software, a deviation indicator in front of the aircraft pilot to direct the flight, a full screen display with controls in front of the operator, a Novatel 3 951R GPS receiver card mounted in the AGNAV console and a Novatel GPS antenna mounted on the EM bird.

Survey co-ordinates are set-up prior to survey and the information is fed into the airborne navigation system. The co-ordinate system employed in the survey design was NAD27 - UTM Projection, Zone 16. The raw pseudorange (C/A-code) calculated GPS positional data is recorded in WGS-84 latitude and longitude at one second intervals directly in the geophysical data file. The raw pseudorange GPS data itself is also stored in a separate file by the acquisition system. This data could be used for differential GPS post-processing if required.

Digital Acquisition System

The Picodas PDAS-1000 data acquisition system was used to collect and record the geophysical and positional data. The data was recorded on an internal hard drive and then transferred to 100Mb capacity Zip disks. An RMS analog chart recorder was linked to the acquisition system for real time profiles on paper that the operator could use for quality control.

All the maps show the flight path trace with time reference fiducials marked at a 10 second interval as well as skeletal topography of elevation contours, lakes, rivers, streams, and swamps.

The basic map coordinate/projection system used is NAD27 - Universal Transverse Mercator Zone 16. For reference, the latitude and longitude are also noted on the maps.

Stacked profile sections for each survey line have been prepared as Geosoft *.map files. Parameters shown on the stacked profiles include the six frequency pairs of EM data, EM bird height, calculated Terrain Model (DTM) and magnetic intensity. The time reference fiducials and UTM co-ordinates are indicated along the x-axis. They can be used to help locate the profiles on the plan maps.

Also plotted beneath the EM traces are the picked anomaly symbols. The same symbols are found on the plan maps and described in the plan map legend.

The digital profile raw and processed data is archived on CD-ROM in Geosoft GDB and XYZ format. In addition, the geophysical maps and stacked sections in Geosoft format are included. A description of the file format may be found in the appendices of this report.



7. DATA PROCESSING AND PRESENTATION

All in-field and post-field data processing was carried out using Geosoft Montaj as well as AeroQuest proprietary data processing software. Plotting was on a 36 inch wide HP650C ink-jet plotter.

7.1 Base Map

The geophysical maps accompanying this report are based on positioning in the datum of NAD27-Canada Mean The survey geodetic OPS positions have been map projected using the Universal Transverse Mercator projection in Zone 16.

A summary of the map datum and projection specifications are as follows:

Ellipse: Clark 1866Ellipse major axis: 6378206.4m eccentricity: 0.082271854Datum: North American 1927 - Canada MeanDatum Shifts (x,y,z): 10, -158, -187 metresMap Projection: Universal Transverse Mercator Zone 16 (Central Meridian 870 W)Central Scale Factor: 0.9996False Easting, Northing: 500,000m, Om

The skeletal topography underlying the maps was provided by Aurora Platinum Corp. from the digital National Topographic Data Base which is based upon the 1:250,000 National Topographic Series (NTS) maps. This database is exhibits a greater positioning error of the various geographic features as well as a reduced resolution compared to the 1:50,000 scale digital database .

7.2 Flight Path A Terrain Clearance

The position of the survey helicopter was directed by use of the Global Positioning System (GPS). Positions were updated every second and expressed as WGS84 latitude and longitude calculated from the raw pseudorange derived from the C/A code signal. Since selective availability was disabled, positional accuracy of up to +I- 6 metres may be obtained.

The instantaneous GPS flight path, after conversion to the local datum UTM co-ordinates, is drawn using linear interpolation between the x/y positions. The time reference fiducials are drawn on the map at appropriate intervals and are used to reference the data file to the plan map.

The height of the EM bird above ground along line is plotted as gridded offset profiles on a separate map.



The Digital Terrain Model (DTM) was derived by taking the satellite position altitude and subtracting the radar altimeter. No correction was made for the constant difference in position of the altimeter antenna (on bottom front of helicopter cabin) and the OPS antenna (on the tail boom). The calculated values are relative and are not tied to surveyed geodetic heights.

7.3 Electromagnetic Data

A two stage digital filtering process was used to reject major sferic events and to reduce system noise in the IMPULSE electromagnetic system.

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 0.4 sec 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 2 seconds. This filter is referred to as a 20 point linear filter.

The EM channels have been levelled to remove the residual zero offset by the use of a short background line at the beginning, middle, and end of each flight. The background line is flown at high altitude (M000 ft), theoretically far enough away from any ground conductivity response. Any residual response is therefore a system offset and can be removed from the on-line response by virtue of linear interpolation between the start and end of flight checks. If any non-linear drift remains in the data then artificial local levelling lines were employed. Any remaining long wavelength response of around l ppm or less may be considered background low amplitude error and may be disregarded.

During the high elevation checks, an internal (Q-Coil) calibration pulse in all EM channels was generated in order to ensure that the gain of the system remained constant and within specifications.

The EM profiles on the stacked sections were examined and discernible bedrock anomalies were noted. Surficial conductors are ubiquitous and typically feature a very strong broad quadrature response and a poor or negligible inphase response. These anomalies are often found over shallow lakes and swamps. Only those anomalies that exhibited a good inphase response at the low frequencies were picked.


Aurora Platinum Corp. - AE M Project

The anomalies are classified as follows:

i) Type 0: suspect or marginal anomalies that are within noise levels and would notnormally be considered, however they have a similar response on an adjacent line or have a coincident magnetic anomaly. They are indicated on the map with an "X"

ii) Type l: well defined probable bedrock source with positive inphase and quadrature response in the low frequency channels. They are indicated on the maps with one of seven different symbols reflecting the modelled conductance.

iii) Type 2 those anomalies that had a pronounced negative inphase response due tomagnetic permeability yet had a positive quadrature response which indicated coincident anomalous conductivity within the source. They are indicated on the maps as an open box with a superimposed cross.

iv) Type 3: includes those anomalies that to be caused by culture, such as buildings, or powerlines. They are indicated on the maps with a solid triangle.

Each anomaly has been given an identifying letter label. The positive inphase anomalies are plotted on the plan maps with a classified symbol denoting the interpreted conductance (conductivity-thickness) of the source in Siemens as well as depth in metres. In addition, the peak low frequency coaxial inphase response values are noted alongside the anomaly symbols. Weaker anomalies where the conductance could not be reliably estimated are denoted by a simple symbol without any labels other than a letter. Occasionally there would be responses that are marginal and questionable, i.e. that are within the noise envelope of the system, but were worth consideration because of a similar response on adjacent lines or perhaps a coincident magnetic high. These anomalies were picked and are indicated on the maps with a simple "X". They should otherwise be disregarded unless there is some other compelling solid evidence to suggest they are in fact real and caused by bedrock mineralisation.

Highly magnetic mineralisation will often give rise to negative inphase anomalies. If the magnetic source is also electrically conductive it may exhibit a coincident positive quadrature response with a complimentary shape. These types of anomalies were ubiquitous in the current airborne dataset. The conductive and magnetic anomalies are identified on the geophysical maps by a box with a cross. Unfortunately the negative inphase precludes the use of the standard interpretation diagrams to estimate a conductance or depth to top of the source.

A listing of all anomalies may be found in the appendix.

The apparent weight percent magnetite content of the subsurface was calculated using the Fraser method whereby:

Wa- 504V.7(2.37V.*267) and

Wâpparent weight percent magnetite Vâpparent volume percent magnetite Rôw frequency coaxial inphase response in ppm aêrrain clearance in metres

The weight percent data was gridded and windowed to accept only values greater than Q.5% in order to reduce noisy data due to residual levelling error.

The pseudo-layer half-space model was employed to derive an apparent resistivity plan map. Given the large amount of high frequency response due to surficial conductors, the mid frequency coplanar coil dataset was chosen to generate the apparent resistivity map. It is generated by using a look-up table to determine the resistivity for a given inphase and quadrature response. In the presence of an inherent levelling error of 1-5 ppm, the threshold response for determining the resistivity was set to 5 ppm.

7.4 Magnetic Data

The Total Magnetic Intensity (TMI) data were corrected for diurnal variations by adjustment using the magnetic base station and the tie lines. No corrections for the regional reference field (IGRF) were applied. The corrected profile data were interpolated on to a grid using a random grid technique. The cell size was 25 metres. Levelling errors caused by the rapidly alternating terrain clearance were removed by micro-levelling the grids. The final levelled grid provided the basis for threading the presented contours. The minimum contour interval varies to accommodate the magnetic relief in a given map.

The vertical gradient (1st Vertical Derivative) of the magnetic field was calculated using Geosoft's MAGMAP programme. Basically, the algorithm takes the fourier transform of the spatial domain total field magnetic grid and then applies a gradient operator and an upward continuation operator to remove high frequency noise. The frequency domain data is then returned back to the spatial domain and plotted as a colour image. It was then contoured..

IMPULSE Helicopter Electromagnetic (HEM) System

The IMPULSE EM is a digital helicopter-borne frequency-domain electromagnetic system developed by AeroQuest and introduced into the commercial geophysical survey market at the beginning of 1997. This innovative wideband frequency-domain system utilizes a single computer-controlled, high-output transmitter driver to power single horizontal coplanar and vertical coaxial transmitter coils, producing a total of six frequencies (three in each coil orientation). This differs significantly from conventional multi-frequency systems currently used in the industry in that the conventional systems use a multitude of independent coils (e.g., a separate and independent coil set for each frequency). As a result, the IMPULSE approach can avoid many of the pitfalls associated with a plethora of coils, all interacting with each other. Furthermore, the common coil approach used in IMPULSE has the potential to minimize system baseline drift and the often seen disparate performance of the many superimposed coil sets found in traditional frequency-domain systems. In addition, the IMPULSE system uses a larger diameter tubular coil platform (30" as opposed to the traditional 20") which permits the system to generate larger dipole moments, thereby resulting in an improved signal-to-noise ratio...all of which quickly translates to better integrity of the measured inphase and quadrature data and an improved depth of exploration.

Number of operating frequencies: 6 total (3 coaxial, 3 coplanar Typical operating frequencies (Frequencies are software selectable)

Coaxial: 870, 4350, 21750 HzCoplanar. 930, 4650, 23250 Hz

Coil orientations: Horizontal coplanar and vertical coaxial Tx-Rx coil separation: 6.5 m Typical transmitter dipole moments:

Coaxial: 870 Hz -150 Am2 peak. 4350 Hz-150 Am2 peak 21750 Hz-15 Am2 peak.

Coplanar: 930 Hz - 200 Am2 peak. 4650 Hz-100 Am2 peak. 23250 Hz-15 Am2 peak.

Outputs: 6 inphase and 6 quadrature channels calibrated in ppm Noise levels: Less than 1 ppm rms under ideal conditions Base-Line drift: Less than 15 ppm per hour after initial warm-up Output time: constant 0.033 seconds Output sampling rate: 30 per second System power: 30 Amps maximum at 22-28 VDC Tow cable: 40 metres long with Kevlar strain member and weak-link Temperature range: -30 to +S5 degrees Celsius Overall bird dimensions: 76 cm diameter, 7 m length Overall bird weight: 200 kg
