1 INTRODUCTION
At the request of Mr. Brian Fowler, a Magnetic survey was performed on the Killala Lake Property. The geophysical survey was calTied out in April 2007 and it included a Mag survey over various grid lines . The survey grid totalled 6.5 km. This property is located southwest of the Manitouwadge camp, a few kilometers southwest of the Killala Lake Alkalic Complex. A Mag survey was performed over two (2) new grids to highlight areas of potential mineralization.
2. PROPERTY, LOCATION AND ACCESS
The Killala property is located in the KillaJa - Vein Lake area of the Thunder Bay .\!fining District, approximately 60 km southwest of Manitouwadge and 240 km northeast of Thunder Bay. The property can be accessed by logging roads on Hwy 17. The logging roads are then travelled for aboUl 30 kilometers north to the property.

The base station was located approximately 50 m away from the edge of a base cabin at
coordinates approximately 531311E and 5434636N (UTM ZONE 16 NAD 83).
The base station magnetometer recorded the diurnal variations of the earth's magnetic field
each day. The base station clock was synchronized with that of the mobile ground
magnetometer to permit subsequent removal of diurnal drift.

7. SENSOR ORIENTATION
Optimal signal strength was achieved by orienting the base station and the portable sensor
along magnetic north. The Scintrex ENVI MAG proton magnetometers require that the
sensors be aligned along magnetic north for maximum field strength coupling during data
acquisition.
8. SIGN CONVENTION
All survey lines in the claim ran in an North South direction. A positive (North and East)
and negative (South and West) sign convention was adopted for all survey readings.
9. DIURNAL CORRECTIONS
8
Diurnal variations caused by atmospheric effects such as ionospheric activity were accounted
for in the data each day by correcting the mobile data against base station data. Magnetic
corrections were part of daily QC/QA data checks.
10. FIELD WORKSTATION
A Intel P4 laptop was used onsite to verify data quality and completeness. Base stations and
mobile readings were transferred from the ENVI data consoles to a laptop and imported as
xyz's into a Geosoft Oasis Montaj database. The database enabled visual on screen display
of both positional and geophysical data for quality control purposes.
Lastly, the report was written by Mike Vumbaca B.Sc. and Pierre Simineau, geol. M.Sc.
The maps were drawn up by Pierre Simoneau.

12. REGIONAL GEOLOGY
9
The bedrock is predominantly of Precambrian age and may be considered in five distinct groups: metavolcanics, migmitites, granitic rocks, mafic intrusive rocks, and alkalic rocks.
Aprroximately sixty percent of the entire area is underlain by granitic rocks which may represent three ages of intrusion.
Each of the previously mentioned rock types have been cut by diabase dikes of the porphyritic and non-porphyritic type.
The youngest rocks within the area are those of the Killala Lake Alkalic Complex, northeast of Killala Lake.
13. PROPERTY GEOLOGY
The property is situated west of Killala Lake, southwest of the Killala Alkalic Complex.
The geology id dominated by a northeast-southwest striking sequence of migmatites.
A considerable amount of mineral exploration has been done in the Killala Lake area and several small copper showings have been found. Some of the occurrences are found at the boundaries of diabase dikes while others are located along strike shears in the metavolcanics or migmatic rocks.
14. FIELD WORK AND PROCEDURE
The geophysical operator moved to the property and the grid was done from mid to late April 2007.
The lines were cut and gridded with a 25m long chain. Two separate grid were cut and bth extend in an N-S direction. The western grid extends E-W 8+00W to 5+00 W and from 0+00 to 5+00S with 100 meters between each line. The eastern grid extends E-W with N-S lines from 6+00E to 14+00E with 100 meters between each set of lines with chaining from 0+00 to 4+00N or 6+00N. A baseline intersects the grid at 0+00.
The magnetic survey covered the lines of the grid for a total of 6.5 km. Measurements were taken every 25 meters between stations.

15. MAGNETIC SURVEY
15.1 PVRPOSE OF THE MAGNET]C SVRVEY AND METHODOLOGY
Magnetic surveys are useful in exploration as magnetic anomalies mostly represent changes in the physical properties of subsurface rocks. The property of a rock determines its magnetic effects and the intensity of its magnetization. During a survey, the total magnetic field is measured and a total field map is processed and produced that allows for the definition of both near-surface magnetic bodies.
The measurements for the magnetic total field were taken at a two (2) second sampling rate between a 25 m station to station spacing interval along ali lines.
15.2 PRESENTATION OF THE RESULTS
Geophysical data were processed and presented on maps using the computer software programs; Geosoft and MicroStation.
The magnetic results are presented on a profile map (no. 1) and a total field contour map (no. 2) at the metric scale of 1 : 2 500. The profiles appear as red lines at a vertical scale of 1000 gammas per centimetre, with a base value of 0 gammas.
15.3 RESULTS OF THE MAGNETIC SURVEY
The property magnetic background is around 57,700 gammas with a maximum of 59,243 gammas and a minimum of 57,154 gammas. The Magnetic colour contour map shows that the migmatite is magnetic since the northwest corner of the eastern grid where the migmatite is crossing shows high magnetic values (Mag-5). Under this assumption, one might also determine that the western grid is also underlain by migmatites (Mag-l and Mag-2) from the strong magnetic signature
16. DISCUSSION OF THE GEOPHYSICAL RESULTS
The geophysical survey covers five (5) magnetic horizons.
The survey arca is characterized by a series of three (3) high magnetic anomalies that may correspond to the migmatites horizons that are crossing the grid. Two magnetic anomalies CMag-2 and Mag-3) may follow dikes that could be carrying sulphides.
17. CONCLUSION and RECOMMENDATIONS
The Magnetic survey gives a good image of the geology and helps to discriminate numerous magnetic horizons.
11
Prospecting and sampling will follow with an emphasis on the areas of higher magnetism.
A tighter station to station spacing of 10m or 12.5m rather than 25m would enhance the higher frequency and shallower wavelengths in the order of five (5) meters. A tighter, more detailed survey should be run in the future to enhance smaller scale anomalies, less than five (5) meters.
