1.0 Introduction

During the period December 6/07 through to January 12/08 an exploration program was carried out over four mining claims situated in Concessions 2 in the southeast comer of Cap reo I Township, Sudbury Mining District In general these claims cover large areas of sparsely treed, wet, swampy ground. G.P.S. controlled base lines were established and grid line positions were measured along base lines. Grid line station intervals, at 25 meters, were measured and pickets with written grid co-ordinates were erected. A total of23.05 kilometers of base and grid lines were then surveyed with a fluxgate magnetometer.

2.0 Pro~rty Ownership

"407043 Ontario Limited" is the recorded claim holder (100%), Their address is:-3725 Regional Road #15, Chelmsford, Ontario. POM ILO

2.1 Claims- Capreol township 4209837 to 4209840 4209842 and 4209843 these six claims comprise 21 units and cover:­The west half of Lot 1, Con. I. The south half of the west half Lot 1, Con 2. The south east quarter of the north half of Lot 2, Con.2 All of the west half of Lot 2, Con.2.& and the east half of the east half Lot 3, Con.2. All the west half Lot 3, Con 2. The south half of Lot 4, Con.2.

2.2 Location and Access Grid and survey work performed occurs in the west half of the claim group in Con 2 on the north side of Regional Road 85 and north of the fonner radar base. The Sudbury Airport is 3 kms. southeast of the east property boundary. Road access is available to the southwest end of grid lines "0 & IE".

3.0 Transportation & Grid Work

Personnel involved in grid preparation and survey work are residents of the Greater Sudbury area who traveled daily to and from work by truck and/or automobile. Edward Rose and Frank Racicot established the base line starting point "O"and it's 1200 azimuth on December 6th and 8th

Walter Collins and his son Walter Jr. established control base line 00 and 700N, also tie line 600S.

Transportation & Grid Work Continued

Control lines have chainage pickets at 50 meter intervals while grid lines are picketed at 25 meter stations with line co-ordinates written on pickets. Grid line intersections with the 00 base line were read with a Garmin G.P.S. instrument and readings recorded. Grid work commenced December 7 /07 and was completed January 3 108. Because short sections of grid line have crossed crown land, outside of the actual claim boundary, these line portions have been deleted and no assessment credit is being claimed. For convenience in determining costs the grid is theoretically divided into two grid areas referred to as the West Grid, containing 10.05 kms. ofline, and the East Grid encompassing 13 kms .. , for a line total of 23.05 kms.

4.0 Magnetometer Survey «(objective).

In conducting mineral exploration the main purpose of the magnetic survey is to outline basic and ultrabasic rock types, which generally contain disseminated magnetite and/or pyrrhotite, and also to locate concentrations of pyrrhotite in areas covered with water or overburden.

4.1 Magnetometer survey procedure The instrument used was a Sharpe MF-I fluxgate magnetometer which measures the vertical component of the earth's magnetic field directly in gammas, positive or negative, over a range of 100,000 gammas. This hand held magnetometer requires no orientation and after coarse leveling the magnetic reading is recorded from a meter mounted on the top of the instrument.

Magnetic base reference stations were established at all grid line intersections on the 00 base line. This was achieved by commencing readings at station 0+00 through to line 14 E. All readings are recorded with the time read. After a short waiting period the base line is re-read from 14E back to 0+00 and readings recorded. Assuming minor changes in the duplicated readings, plus or minus 20 gammas, the two readings taken at each line interval are then averaged and this averaged reading becomes the reference reading for making diurnal drift corrections on each line read. Using this correction method all magnetic readings are made relative to the first reading taken.

Magnetometer Survey (Procedure Continued)

During the survey most readings were read on the 3000 gamma instrument Scale. This magnetic survey commenced Dec 28 /07 and was not completed until January 12/08. Snow storms in December and a full week of mild miserable rainy weather, caused very slow progress. Melting snow caused pickets to fall and many actually floated away from their measured locations in this vast swamp area requiring time consuming re-positioning. A total of 906 magnetic readings were taken.

4.2 Magnetometer Survey Results

Drift corrected magnetometer readings have been computer plotted in contour form on a 1 :2000 scale black and white map. Individual magnetic readings are indicated numericly along each grid line surveyed and the exact station position read is indicated wi1h an "X".The 25 gamma contour lines are finer and less prominent than the heavier, more obvious 1 00 gamma lines. In several strongly anomalous magnetic areas only lines of 100 gamma value are used to deHne the anomaly.

4.3 Magnetic Survey Interpretation:

The southern two thirds of the survey area is primarily within the background range of 1750.

Two very minor magnetic low are worthy of mention:-

1) Parelleling grid line 2E is a -50 to -250 gamma low with a strike length of 1.5 kms. No obvious cause can be offered for this weak zone.

.. .4 Magnetic Survey Interpretation (continued)

2) Perpendicular to the grid following the "00" base line is a subtle, 3) 50 to -150 gamma low, which was also noted on aeromagnetic

survey "Map 1511 G, Capreol Township" shown as a much broader low zone but correlating with the plotted position of the Airport Fault on "OGS Map 2491; Sudbury Geological Compilation" Fault zones are often mineralized with pyrite and/or graphite and their weak magnetic low expression may possibly be the result of deep glacial gouging and weathering along such vulnerable zones of weakness.

5.0 Conclusion:

The northern one third of the grid covers high dry ground and rock outcroppings were noted by the field crew. This area contains a very prominent, positive linear magnetic anomaly +200 to +800 gammas above background and an occasional reading occurs in the 4,000 gamma range. The strike direction of this anomaly is also perpendicular to the grid in perfect alignment to one of two parallel, olivine diabase dikes plotted on geological Map 2491 very close to the northeast comer of the grid. A small section of olivine diabase is also plotted just northwest of the northwest comer of the grid on geological "Map No 38G -- Sudbury Basin Area". The significance of olivine diabase is that it generally contains varying amounts of disseminated magnetite resulting in positive linear anomalies which often cut through all other magnetic features on aeromagnetic maps.

Along the northern boundary of the grid there appears to be a second buildup of magnetic values possibly indicating the presence of the second parallel diabase dike previously referred to.

The magnetic survey successfully outlined several anomalies which are explainable with the help of competent geological mapping. It is quite possible that the magnetic low fault zone may be weakly conductive, as many are. This could be checked out with a V.L.F. E.M. unit if the property owner is interested.O

6.0 Recommendation:

One day of prospecting in the area where the strong linear zone occurs would probably verifY the above interpretation.
