5 5 1. INTRODUCTION At the request of Mr. Brian Fowler, a Magnetic survey was performed on the Lunny Lake Property. The geophysical survey was carried out in April 2007 and it included a Mag survey over various grid lines. The survey grid totalled 6.7 km. This property is locatedin the Archean Schreiber-Hemlo Greenstone Belt that is part of the Abitibi-Wawa Shebandowan Subprovince of the Superior Province. The grid was cut to cover a base metal target and three (3) showings. A magnetic survey was performed over the grid are to highlight areas of mineralization. 2. PROPERTY, LOCATION AND ACCESS The Lunny Lake Property is located in the Wabicoba Lake area of the Thinder Bay Mining District, approximately 16 km northeast of the three producing Hemlo Gold Mines and 330 km east of Thunder Bay. The property can be accessed by the Dead Otter Lake/Twist Lake roads at a point about three kilometres east northeasterly of the Property. Figure 1. Localization of the Lunny Lake Property

Data dump in memory or on a line by line basis in digital or hardcopy formats. 2.3 Ah Lead Acid battery. 12 V at 0.65 Amp -40 to 60 C. Humidity 0-100% Fully sealed desiccant cartridge. 6. BASE STATION Same as above (section 5) except for; Cycle Time: Data Memory: Internal - minimum is determined by the reading period, max 9999 sec in 1 sec intervals 28, ,000 readings. Power Supply: 12 V external battery The base station was located approximately 50 m away from the edge of a base cabin at coordinates approximately E and N (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 8 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 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 QCIQA 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. 11. PREVIOUS WORK The following companies have worked in the general area of the Lunny Lake Property, namely: Cecil Von Klein and his associates staked 134 claims and the property was optioned to McIntyre Porcupine Mines Ltd. The company carried out a program of linecutting, geological mapping, and ground geophysical surveys in the past. Discovery of a number of copper-nickel and copper-lead-zinc occurrences. Electromagnetic conductors and magnetic anomalies were teseted with 28 diamond drill holes. Good copper, zinc, silver, gold and lead values were obtained from drill holes around #4 showing. Caravelle Mines Ltd. acquired control of the McIntyre property and called it the Pulfa prospect. The Pulfa prospect consists of 253 contiguous claims. Associated companies have carried out evaluation work over the area in the past. The work consisted of photo-geological and aeromagnetic interpretations, reinterpretation of previous information, geochemical soil surveys, ground electromagnetic, magnetic, and IP surveys, geological

9 9 mapping and drilling. Most of the drilling was focussed around the #4 Showing and the A Zone. Caravelle confirmed the results obtained by McIntyre under the #4 Showing Geologists of the Geological Branch, Ontario Department of Mines carried out field mapping of the Black River Area during the various summer seasons (Milnes 1968). A combined airborne geophysical survey was flown between June 11 th and 13 th for Caravelle Mines Ltd. By Se1co Exploration Company Ltd. With a Mark IV INPUT and 200 meters spacing and variable line directions. A number of weak anomalies were detected. Arrangements for further developments on the mining property were taken with Fa1conbridge Nickel Mines, dated January 31 st, A ground magnetic and AFMAF-Longwire surveys were carried out over the claims by Central Geophysics Limited of Winnepeg. Some diamond drill holes were done but the claims were dropped. Noranda Exporation Co. Ltd. Completed an airborne survey and some geological mapping, Magnetics and VLF. Noranda Exporation Limited carried out further drilling in the area. Seven drill holes were completed, numbered PN-1 to PN-7. Drilling was focussed around the #4 Showing and to the south thereof. Noranda confirmed the values obtained by McIntyre and Caravelle under the #4 Showing. Noranda also drilled several holes south and southeast ofthe #4 Showing. Holes PN-2 under the #4 Showing returned 1.5m assaying 0.69% copper, 0.93% zinc and g silver per ton. 12. REGIONAL GEOLOGY The Lunny Lake Property is located within the Archean Schreiber-Hemlo Greenstone Belt that is part of the Abitibi-Wawa-Shebandowan Subprovince. The Black River area is underlain by an assemblage of Archean greenstones, intruded by granitic plutonic rocks. The mafic metavolcanics formation, which includes pillowed units, has been interpreted as the oldest and lowermost horizon of a gradational sequence. The mafic metavolcanics grade upward into intermediate metavolcanics, felsic metavolcanics, pyroclastic rocks (agglomerates) and sediments. The property is situated on the northern portion of the synform and dominated by east-west striking sequences of metavolcainic and sedimentary rocks bounded to the south by the Lusher Lake Pluton.

10 PROPERTY GEOLOGY The Lunny Lake property is underlain by Mafic metavolcanic rock from the lowermost stratigraphic unit and consists of pillowed flows which grade into fine to medium and medium to course grained amphibolites. Tops determination taken from pillows indicates a south younging direction. Interflow sediments, tuff and iron formation are found intermixed within the mafic flow. A calcsilicate unit intermixed with felsic to intermediate flows and pyroclastic rocks overlies the mafic volcanic. The sequence grades in tum into a thick succession of metasediments consisting essentially of conglomerates and greywacke. Locally, the emplacement of the Dotted Lake Pluton has produced a large easterly plunging anticline. The Theresa Lake property is located on the southern limb of this structure. Three parallel interflow sedimentary units have been traced in a fairly continuous fashion across the entire property. These units consist of laminated greywacke, arkose, argillite, calcareous mafic to felsic volcanogenic sediments and tuffs and fine-grained amphibolite interbedded with chert, banded sulphide and banded magnetite-amphibole. Though these units could be labelled as iron formations, banded magnetite probably accounts for less than 5% of the sequence in each unit. Each unit contains highly anomalous amounts of gold mineralization, as well as minor chalcopyrite, sphalerite, and molybdenite. The lowermost unit is in contact with the Armand Lake Porphyry. They vary in thickness from 15 meters to less than 1 meter. Compositionally, they are quartz-feldspathic, probably derived from exhalative chert, siltstones or clay beds. 14. FIELD WORK AND PROCEDURE The geophysical operator moved to the property and the grid was done from mid to late April The lines were cut and gridded with a 25m long chain. The grid extends E-W with N-S lines from 6+00W to 0+00 with 100 meter line to line spacing, and from 0+00 to 4_50E and from 7+00E to 9+00E, with 50 meters between each set of lines. A baseline intersects the grid at 4+50N. The magnetic survey covered the lines of the grid for a total of 6.7 km. Measuremnets were taken every 25 meters between stations. 15. MAGNETIC SURVEY 15.1 PURPOSE OF THE MAGNETIC SURVEY 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.

11 11 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 all lines 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: The profiles appear as red lines at a vertical scale of 1000 gammas per centimetre, with a base value of 0 gammas RESULTS OF THE MAGNETIC SURVEY The property magnetic background is around 57,700 gammas with a maximum of 60,879 gammas and a minimum of 54,290 gammas. The Magnetic colour contour map shows a main Iron Formation south of the Base line at aroud 3+25N and seems to continue but weaken on lines 7+00N to 9+00N anround 4+50 N. The total field results have provided three (3) magnetic horizons with a predominant northwest-southeast trend. At least four (4) thin high linear magnetic anomalies cross the grid area. These features may possibly be related to thin iron formations. 16. DISCUSSION OF THE GEOPHYSICAL RESULTS The geophysical survey covers gold bearing zones. The grid extends 1500 meters in length to cover zones 2, 4 and 5 and the area in between. The survey area is characterized by a series of high magnetic anomalies that may correspond to iron formations that appear to cross the grid. One VLF anomaly appears to coincide well with the main Mag Axis and could be characterized by sulfides CONCLUSION and RECOMMENDATIONS The Magnetic survey gives a good image of the geology and helps to discriminate numerous magnetic horizons. In particular, one of the magnetic layers corresponds to a VLF anomaly that could be related to a sulphide bearing zone. Prospecting and sampling should be followed up with an emphasis on the areas of higher magnetism. A closer station to station spacing of 10m or 12.5m 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. A detailed survey would confirm the ground truth of any longer wavelength anomalies.
