1. Introduction

1.1. Executive Summary This report describes the specifications and parameters of an airborne geophysical survey carried out for: KODIAK EXPLORTION LIMITED 1205 – 700 Pender Street West Vancouver, BC, V6C 1G8 Attention: W. S. Chornobay, President Phone: 604-688-9006 Fax: 604-688-9029 The survey was performed by: TERRAQUEST LTD., 2-2800 John Street, Markham ON, Canada, L3R 0E2 Phone: 905-477-2800 ext. 22, Email: [email protected]. The purpose of the survey of this type is to collect geophysical data that can be used to prospect directly for economic minerals that are characterized by anomalous magnetic, conductive or radiometric responses. 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. The lines are oriented to intersect the geology and structure so as to provide optimum contour patterns of the geophysical data.

1.2. Location The survey is located in northern Ontario, north of Lake Superior, within the Beardmore – Geraldton – Longlac belt. The survey is comprised of two blocks referred to as West Block and East Block. The West Block is located in parts of Irwin, Walters, Pifher and Elmhirst Townships, approximately 40 kilometres west of Geraldton, 15 kilometres northeast of Beardmore and 5 kilometres northwest of the hamlet of Nezah. Highway 11 passes to the south and road 801 passes through the West Block. It is irregular in shape with five sides and measures 14 kilometres wide and a maximum of 13 kilometres high (north-south). The centre of the area is approximately 49 degrees 44 minutes north and 87 degrees 46 minutes west.

The East Block surrounds the town of Geraldton and includes portions of Legault, Vivan, Colter, Hipel, Parent, Lindsley, Kirby, Salsberg, Errington, Fulford, McKelvie, McQueensten, Coltham, and Arby Townships. The survey block is irregular in shape with 40 sides. The maximum dimensions are 66 kilometres wide (east-west) and 25 kilometres high (north-south). The centre of is approximately 49 degrees 40 minutes north and 87 degrees 13 minutes west.

2.4. TOLERANCES - REFLIGHT

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 intended line separation over a distance greater than 1 kilometre.

2. Terrain Clearance: The aircraft mean terrain clearance was to be smoothly maintained at 70 metres MTC in a drape mode. Re-flights were done if the final differentially corrected altitude deviated from the specified flight altitude by +/-10m over a distance of 3 kilometres or more if, in the pilot’s opinion, it was safe to do so.

3. Diurnal Variation:

Diurnal activity in the survey was limited to 20 nT deviations from 5-minute chord.

4. GPS Data: GPS data included at least 4 satellites for navigation and flight path recovery. There were no significant gaps in any of the digital data including GPS and magnetic data.



11

5. Radio Transmission:

The aircraft pilot makes no radio transmission that interferes with 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 cumulative total of 1000 metres for the radiometric survey.

2.5. 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. The flight path guidance accuracy is variable depending upon the number and condition (health) of the satellites employed. The accuracy was for the most part better than 10 metres. Real-time GPS correction using the Trimble receiver and Omnistar broadcast services for North America improves the navigational accuracy to about 3 metres or less in the horizontal plane and 4-5 metres in the vertical direction.

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 flew 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 referred to as the FOM.

5.2. MAGNETIC LAG A magnetic lag test was performed by flying a line with discrete anomalies in opposite directions to determine the time lag of the airborne system.

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

5.4. 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.

5.5. RADIOMETRIC SENSITIVITY FACTORS The radiometric system sensitivity was determined from measurements acquired over the Breckenridge calibration test site monitored by the GSC.

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

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

6. LOGISTICS

6.1. PERSONNEL The contractor supplied the following properly qualified and experienced personnel to carry out the survey and to reduce, compile and report on the data: Field: Pilots Justin Wagner, Jason Long Mike Bisono, Mike Palmiter Operator Pat Murphy Geophysicist Kendahl Pomeroy Office: Chief Geophysicist Allen Duffy Geophysicists Kendahl Pomeroy, Brian Sargent, Pat Marchesi, Carolyn Boone Manager Charles Barrie

6.2. FLIGHT REPORTING The aircraft and operator arrived on July 29, 2008 and the geophysicist arrived on July 30. The survey was flown in 25 flights, (N87V-591-615) including all test and calibration flights, over 22 days from July 30th to August 20th. A total of 4 whole days and 2 half days were lost to aircraft maintenance and 1 whole day and 3 half days to weather. Airborne survey was performed on 8 whole days (2- flight days) and 4 half (1-flight) days.

6.3. BASE OF OPERATIONS The base of operations was at the Geraldton airport, Ontario, in the north central part of the survey area. The base station (combined high sensitivity magnetic and GPS) was set up at the airport well away from cultural interference. Accommodations for the crew were at the White Wolf Resort, telephone 807-854-1519. High speed satellite internet was available but not always reliable.

7. Data Processing

7.1. DATA QUALITY CONTROL The field data were transmitted via internet back to the office to inspect the data for quality control and tolerances on all channels. This included any corrections to the flight 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 In the first step the raw magnetic data was compensated for aircraft motion effects using data from the fluxgate sensor. 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 (16.12 metres), 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 (10.78 metres). Both gradients were “DC shifted” by subtracting the median value on a line-by-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. The RTF is a coherent, detailed and well leveled product but does not contain the low to lower-mid wavelength components; because the units are pseudo nT it should not be used for quantitative modelling. In the final correction process, the compensated tail sensor magnetic data were corrected with standard tie-line intersection leveling. The intersections of traverse and control lines were calculated and the difference in observed magnetic values was attributed to diurnal variation. In some active areas, with steep magnetic gradients, the difference reflects not only diurnal, but also some error due to small inaccuracies in both horizontal and vertical position at the line intersection. If the implied diurnal correction at these intersections was inconsistent with adjacent diurnal indications, the indicated correction was ignored. The correction applied was a linear sloping datum connecting the interpreted diurnal value at each control line intersection. The vertical magnetic gradient was subsequently calculated from the final processed total

magnetic field data grid (originating from the Tail Sensor). The finalized datasets were gridded with minimum curvature procedure with a cell size of 25 metres. Note that the extra non-contracted portions (2,176 km, see section 2.1) were flown and processed and provided on the final maps. The altitude of the aircraft was uncontrolled over the settlement of Geraldton, therefore caution should be exercised in the interpretation of data from this area. West Block- Total Magnetic Field

7.3. FINAL ELECTROMAGNETC DATA PROCESSING The Terraquest XDS system produced good resolution and consistent results. The Terraquest XDS-VLF system is currently in the developmental stage and as such only basic processing has been performed on this data. The x, y and z components of the XDS-VLF-EM data in the range of 22.0 to 26.0 kHz (which include Cutler and Seattle transmitter signals), were inverted, normalized, mean leveled and micro-leveled. The data were gridded with a cell size of 25 metres and presented as contour plots of the a) Line Field (Vcx) coil, b) Ortho Field (Vcp) coil and c) Vertical Field (Hcp) coil.

7.4. FINAL RADIOMETRIC DATA PROCESSING The radiometric data were processed according to guidelines established in the definitive IAEA Technical Report “Airborne Gamma Ray Spectrometer Surveying” (IAEA 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: 201 - 233 Cosmic (>3 MeV): 255

• Since the PicoEnvirotec GRS410 Spectrometer does not suffer from conventional

measurement “dead time”, no discrete correction for this effect need be applied.

• The raw count rates were corrected for static and ambient background sources (Aircraft, Cosmic and Radon) by using measurements from 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 for 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 four 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 ‘Savitsky-Golay’ filter, designed to reduce sample overlap effects. This five-point convolution filter has the following (normalized) coefficients:



26

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

effective 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 for each of the four integral windows are as follows:

Total Count : Exposure Rate, nano Gray/hour Potassium : Percent (%K) Uranium: Parts per Million equivalent Uranium (ppm eU) Thorium: Parts per Million equivalent Thorium (ppm eTh)

The radiometric data were gridded by minimum curvature method with a cell size of 25 metres and contoured. West Block – Total Count

8. SUMMARY An airborne high sensitivity magnetic, XDS VLF-EM and gamma ray spectrometer survey was performed over the Geraldton – Beadmore Project, on two areas referred to as West & East Blocks in northern Ontario, with 70 metre mean terrain clearance, 100 metre line intervals, 1,000 metre tie line interval, and with data sample points at 8 metres along the flight lines. The base of operations was at Geraldton, 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 final processing to produce two sets of the following colour maps:

a) Magnetics: total magnetic intensity of tail sensor and first vertical derivative, lateral and longitudinal gradients

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

All data have been archived as Geosoft database (GDB); all MAP and GRID files used to make the maps and this report are included in the archive. Respectfully Submitted,

Charles Barrie, M.Sc. Vice President Terraquest Ltd.
