1. Introduction

1.1. Executive Summary

This report describes the specitications and parameters of an airborne geophysical survey carried out for:

ST ARFIRE MINERALS INC. 520-355 Burrard Street Vancouver. BC V6C 2G8

Attention: Norm Elliot Phone: 604-669-5642 Fax: 604-687-6714

• The survt:y was performed by:

•

TERRAQUEST LTD., 2-2800 John Street. Markham ON. Canada L3R OE2

Phone: 905-477-2800 ext. 22 Email: howard@terraquest.ca.

The purpose of the survey of this type is to collect geophysical data that can bt: used to prospect directly t~Dr anomalous magnetic. conductive and radiometric areas in the earth's crust which may be caused by or related to economic minerals. Secondly, the geophysical patterns can be used indirectly for exploration by mapping the geology in detaiL including faults shear zones, folding. alteration zones and other structures.

To obtain this data. the area was systematically traversed by aircraft carrying geophysical equipment along parallel flight lines spaced at even intervals and oriented so as to intersect the geology and structure in a way as to provide optimum contour patterns of the geophysical data.

2.5. TOLERANCES - REf LIGHT

1. Traverse Line Interval

Re-flights would take place if the flight line separation of the final differentially corrected flight path is greater than 1.25 of the line spacing from the intended flight path over a distance greater than I kilometres.

2. Terrain Clearance:

The aircraft mean terrain clearance was to be smoothly maintained at 70 metres MTC in a drape mode. Re-f1ights were done if the tinal differentially corrected altitude deviated from the specified flight altitude by +1-10m over a distance of 3 kilometres or more it: in the pilot's opinion, it was sate to do so.

3. Diurnal Variation:

Diurnal activity during the survey was limited to 20 nT deviation from a 5-minute chord.

4. GPS Data:

GPS data included at least four satellites for accurate navigation and flight path recovery. There were no significant gaps in any of the digital data including GPS and magnetic data.

S. Radio Transmission:

The aircraft pilot makes no radio transmission that interteres with the magnetic response.

6. Sample Density: A reflight is required if the sample density along one or more of the survey lines exceeds 10 metres over a cumulative total of 1000 metres for the magnetic survey. and 100 metres over a cumulati ve total of 1000 metres for the radiometric survey.

2.6. NAVIGATION

The satellite navigation system was used to ferry to the survey sites and to survey along each line. The survey coordinates were supplied by the client and were used to establish the survey boundaries and the flight lines.

High Resolution AeromagnetIc. XDS VLF,EM & Radiometric Survey. Slater & Suganaqueh Projects. Montreal RH't!f. Ontario

The flight path guidance accuracy is variable depending upon the number and condition (health) of the satellites employed. The selective availability normally imposed by the military was at a minimum during this period and consequently the accuracy was for the most part better than 10 metres. Real-time GPS correction using the Trimble receiver and Omnistar broadcast services tor North America improves the navigational accuracy to about 3 metres or Jess in the horizontaJ pJane and 4-5 metres in the vertical direction.

4. Base Station Equipment

4.1. BASE STATION MAGNETOMETER High sensitivity magnetic base station data was provided by a cesium vapour magnetometer logging onto a computer and with time synchronization from the GPS base station receiver.

The magnetometer was the same as used in the aircraft, a CS-2 magnetometer manufactured by Scintrex. The magnetometer processor was a KMAG manufactured by Kroum VS Instruments and the data logger was an iP AQ PDA by Hewlett Packard. The counter was powered by a IOVAC 50/60hz to 30VDC 3.0 amp power supply with an internal 12VDC fan. The logging software SDAS-I was written by Kroum VS Instrument Ltd. specifically for the pocket pc hardware. 1t supports real time graphics with selectable windows (uses two liser selectable scales. coarse and fine). Time recorded was taken from the base GPS receiver. Magnetic data was logged at 2Hz. Data collection was by RS232 recording ASCII string and stored on flash card.

5. TESTS AND CALIBRATIONS

5.1. MAGNETIC FIGURE OF MERIT

Compensation calibration tests were performed to determine the magnetic influence of aircraft maneuvers and the effectiveness of the aircraft compensation method. The aircraft tlew a square pattern in the four survey directions at a high altitude over a magnetically quiet area and perform pitches (± 5°). rolls (± 10°) and yaws (±

5°). The sum of the maximum peak-to-peak residual noise amplitudes in the total compensated signal resulting from the twelve maneuvers is refen-ed to as the Figure of Merit (FOM) index.

5.2. RADAR ALTIMETER CALIBRATION A radar altimeter calibration was performed over the runway.

5.3. RADIOMETRIC SAMPLE CHECKS The performance and consistency of gamma ray system was checked before and after each flight day using sample pucks of uranium, thorium and cesium to ensure that there was no change in the system during the survey.

5.4. RADIOMETRIC SENSITIVITY FACTORS The radiometric system sensitivity was determined from measurements acquired over the Breckenridge calibration test site monitored by the Geological Survey of Canada.

5.5. RADIOMETRIC ALTITUDE ATTENUATION The altitude attenuation was determined from the results of flying over the runway.

5.6. RADIOMETRIC COMPTON COEFFICIENTS A pad calibration was performed over the GSC pads in Ottawa.

The field data were couriered back to the office to inspect the data for quality control and tolerances on all channels, This included any corrections to the tlight path, making flight path plots. importing the base station data, creating a database on a flight-by-flight basis. and posting the data. All data were checked for continuity and integrity, Any errors or omission or data beyond tolerances were flagged for re-flight and the crew was notified ready for their flight in the morning,

7.2. FINAL MAGNETIC DATA PROCESSING Raw magnetic data was initially compensated for aircraft motion effects in advance of calculating measured longitudinal and lateral magnetic gradients, The lateral magnetic gradient was calculated by subtracting the left wing sensor reading from the right wing sensor reading and dividing the resulting value by the tip-to-tip separation. yielding the measurement expressed as nT/m, The longitudinal gradient was similarly calculated by subtracting the tail sensor measurement from the average of the wing-tip values normalized by the wing-centre to tail sensor separation. Both gradients were "DC shifted" by subtracting the median value on a line­by-line basis and converted from aircraft-centric to survey grid orientation by selectively inverting (mUltiplying by -1) in the south and westbound directions, The gradient data was subsequently verified by generating a Reconstructed Total Field (RTF) grid using the Lateral and Longitudinal data grids as input.

In the final correction process the compensated tail sensor magnetic data were initially corrected with standard tie-line intersection leveling, Tie line leveled Total Field Magnetic data from the Left Wing. Right Wing and Tail Sensors were subsequently subjected to an enhanced micro­leveling procedure. operating on the regional magnetic component (isolated by removal of the reconstructed Total Field), Leveling in this manner minimizes "damage" to higher frequency geologic anomalies and improves upon residual errors left by traditional tie-line leveling. The vertical magnetic gradient was subsequently calculated from the final processed total magnetic tield data grid (originating from the Tail Sensor). The finalized datasets were gridded with minimum curvature procedure with a cell size of 20 metres.

7.4. FINAL RADIOMETRIC DATA PROCESSING

The radiometric data were processed according to guidelines established in the definitive lAEA Technical Report "Airborne Gamma Ray Spectrometer Surveying" (lAEA Technical Reports Series No, 323, 1991). The following specifics were performed:

• Recorded as a 256 channel spectrum, the four raw integral (or "terrestrial") windows (Total Count, Potassium, Uranium and Thorium) were initially generated by summing the recorded counts between their appropriate channel limits - as specified below: 256 Channel ROI definitions (based on 0-255 channel indices)'

Total Count: 30 - 233 Potassium: 115 - 131 Uranium: 139 - 156 Thorium: 20 t - 233 Cosmic (>3 MeV): 255

• Since the Picoenvirotec GRS410 Spectrometer does not suffer from conventional measurement "dead time", no discrete correction fDr this effect need be applied. The raw count rates were corrected fDr static and ambient background sources (Aircraft, Cosmic and Radon) by using measurements tt'om the frequent over-water crossings encountered during the survey and from pre- and post- flight over-water 'background' lines (where geologic radiation sources are suppressed) .

• The background corrected measurements were corrected tor Compton Scattering by application of "Stripping Coefficients" experimentally determined in a specific calibration exercise using standard large-scale radio-element sources (see Appendices).

• Count rates were further adjusted by correction to constant terrain clearance (altitude attenuation correction). This correction step includes the application of exponential attenuation coefficients, specific to each of the tDur integral windows, determined during a specific calibration procedure (see Appendices).

• As additionally recommended by the Geologic Survey of Canada, the final corrected count rates were passed through an optimized filter, sometimes referred to as a 'Savitsky­Golay' filter, designed to reduce sample overlap effects. This five-point convolution filter has the following (normalized) coefficients:

-.0857,0.3429,0.4857,0.3429, -0.0857 • Corrected radiometric data are delivered both as count rates (counts-per-second) and as

efTective ground units by application of sensitivity factors determined experimentally over the Geologic Survey of Canada's test range (Breckenridge Calibration Range, Ottawa - see Appendices). Applicable ground units fDr each of the fDur integral windows arc as tollows:

Total Count: Exposure Rate, nano-Gray/hour (nGy/hr) Potassium: Percent (%K)

8. SUMMARY

An airborne high sensitivity magnetic, XOS VLF-EM and gamma ray spectrometer survey was performed over the Slater & Suganaqueb Projects Ontario, located respectively approximately 70 kilometres north of Sault Ste Marie and 35 kilometres southeast of Wawa, with 70 metre mean terrain clearance, 100 metre line intervals, 2,000 metre tie line interval, and with data sample points at 6-8 metres along the flight lines. The base of operations was at Sault Ste Marie, Ontario. A high sensitivity magnetic and a GPS base station located at the airport recorded the diurnal magnetic activity and reference GPS time during the survey for adherence to survey tolerances.

The data were subjected to tinal processing to produce two sets of the following colour maps at J :20,000 scale for Slater Block and 1: 1 0,000 scale for Suganaqueb Block:

a) Magnetics: total magnetic intensity of tail sensor. measured lateral gradient. measured longitudinal gradient and first vertical derivative

b) XDS VLF-EM: x, y and z fields c) Radiometries: total count. potassium. uranium. thorium. ternary d) Flight Path e) Digital Terrain Model

All data have been archived as Geosoft database (GOB); all MAP and GRID tiles used to make the maps and this report are included in the archive.
