1.0 Introduction

The Munro property of Big Red Diamond Corporation consists of several

unpatented mining claims, where recent work was performed on mining claims numbered

3016569 and 4241466 located in Munro and Beatty Townships, Larder Lake Mining

Division. During October 2010, a program of gridding and geophysical surveys was

conducted over a portion of this claim group. The geophysical program consisted of total

field magnetic surveying. Hussey Geophysics Inc, from Timmins, Ontario carried out

the magnetometer survey; while Archer Explorer of Edmonton, Alberta completed the

line cutting and chaining. The line cutting and geophysical surveys were completed

between October 6th

and October 28th

, 2010. These surveys were carried out in order to

map any discrete anomalies that may be associated with structural deformation, or

economic concentrations of massive or disseminated sulphide mineralization associated

with gold mineralization.

2.0 Location and Access

The Munro Property is located approximately 16 kilometres east of the Town of

Matheson, Ontario. The claim group straddles the Beatty / Munro Township line in the

Larder Lake mining division. A notable landmark is the old Johns-Mansville waste

tailings pile, behind which the property is located. Access to the property is via highway

101 east from Matheson along highway 101 for approximately 15 kms., then north along

logging roads for approximately 2 km. A trail off of the main logging road served to

access the grid (see figures 1 and 2).

3.0 Summary of 2009 Geophysical and Line Cutting Program

The line-cutting on the Munro Property grid totalled 16.66 kilometres, which

consisted of a 0.75 km. long baseline cut at an azimuth of 90 degrees. Grid lines were cut

and picketed as shown on the grid map and ranged in length from 1100 metres on the east

end of the grid to 1600 metres in the central areas. The grid lines were chained every 25

-5-

metres with pickets chained at 25-meter intervals along all lines. The lines were spaced

and cut at 50 meter intervals.

The geophysical program consisted of total field magnetic surveying. The total

magnetic field survey, using a Gem GSM-19 magnetometer, totaled 16.66 kilometers

with readings collected every 12.5 meters along all lines.

The geophysical data has been presented on plan maps at a scale of 1:5000,

showing the contours and postings of the magnetic data (see maps in pocket).

A description of the instrument and survey method can be found in appendix A.

4.0 Discussion of Results

The magnetic survey on the Munro grid indicates a relatively quiet magnetic

background with magnetic values ranging between 55955 and 56766 nT. The background

magnetic field strength is 56184 nT. The overall magnetic pattern in the grid area

suggest a northwest-southeast strike for the underlying lithology; and is disrupted by

several linear to ellipsoidal shaped anomalous magnetic highs, located between 800S and

600N. These anomalies are clearly evident on the contour map. These four anomalies are

easily identified on the contour map and have been labeled as magnetic anomalies D, E,

F, and G. The anomalies display magnetic amplitudes of up to approximately 600 nT

above background. These magnetic anomalies may reflect underlying mafic lithology

which often gives rise to this type of magnetic anomaly. Anomalies D, E, and F may also

reflect diabase dikes which are prevalent in this area. Magnetic anomaly G displays a

magnetic signature similar to what might be expected from a kimberlite pipe.

In addition to magnetic anomalies D, E, F, and G; several fault zones have been

interpreted within the Munro grid. These anomalies may represent major lithological

contacts or structural anomalies which may be significant in this area. These anomaly

locations are shown on the contour map.

No other significant magnetic anomalies were mapped over the Munro grid.

5.0 Conclusions and Recommendations

The magnetic survey over the Munro grid was successful in mapping magnetic

anomalies that may be prospective for further mineral exploration. It may be possible to

test these anomalies with a program of trenching or prospecting in order to determine

their source lithology.

It is possible that a program of induced polarization surveying would aid in better

defining any mineralized zones, which may have disseminated accumulations of sulphide

or graphitic minerals. These zones are often prospective for gold deposits. A limited

program of either dipole-dipole or pole-dipole IP surveying with an 'a' spacing of 25

meters and reading levels of n=1 to 6 is recommended in order to further evaluate the

Munro property if sufficient other geological evidence exists to support continued

exploration of the Munro claim group.

Any existing geological, diamond drilling or geochemical information that may

exist in the mining recorder assessment files should be investigated and compiled prior to

further exploration of the Munro property in order to accurately assess the area of the

current geophysical survey and to determine the most effective follow-up exploration

method for these anomalies.

Appendix A

Survey Theory - Total Field Magnetics

Magnetic Survey

Theory:

The magnetic method is based on measuring alteration in the shape and magnitude of the

earth's naturally occurring magnetic field caused by changes in the magnetization of the

rocks in the earth. These changes in magnetization are due mainly to the presence of the

magnetic minerals, of which the most common is magnetite, and to a lesser extent

illuminate, pyrrhotite, and some less common minerals. Magnetic anomalies in the earth's

filed are caused by changes in two types of magnetization: (1) Induced, caused by the

magnetic field being altered and enhanced by increases in the magnetic susceptibility of the

rocks, which is a function of the concentration of the magnetic minerals. (2) Remanent

magnetism is independent of the earth's magnetic field, and is the permanent magnetization

of the magnetic particles (magnetite, etc.) in the rocks. This is created when these

particles orient themselves parallel to the ambient field when cooling. This magnetization

may not be in the same direction as the present earth's field, due to changes in the

orientation of the rock or the field. The unit of measurement (variations in intensity) is

commonly known as the Gamma which is equivalent to the nanotesla (nT).

Method:

The magnetometer, a GEM Systems GSM-19 with an Overhauser sensor measures the

Total Magnetic Field (TFM) perpendicular to the earth's field (horizontal position in the

polar region). The unit has no moving parts, produces an absolute and relatively high

resolution measurement of the field and displays the measurement on a digital lighted

display and is recorded (to memory). Initially, the tuning of the instrument should agree

with the nominal value of the magnetic field for each particular area. The Overhauser

procession magnetometer collected the data with a 0.2 nanoTesla accuracy. The

operator read each and every line at a 12.5 m intervals with the sensor attached to the top

of four (56cm), aluminum tubing sections. The readings were corrected for changes in the

earth's magnetic field (diurnal drift) with a similar GSM-19 magnetometer, acting as a

stationary base station which automatically read and stored the readings at every 15

seconds. The data from both units was then downloaded to PC and base corrected values

were computed.
