1.1 Terms of Reference and Objectives of this WorkThis work was initiated in response to a request from Charles Desjardins to conduct a gravity survey with the objective of mapping structure that may be associated with gold mineralization.

As shown in Figure 1, the project area is located about 2 km south of the village of Starratt-Olsen which is about 25 km southwest of Red Lake. The north half of the area is in Baird Township. Access to the area was made by snow machine; from Flat Lake Road (Jubilee intersection ), and from two trails from Starratt-Olsen.

OGS Preliminary geological map P.3196 (Baird Township) covers a good part of the study area. The area is underlain by a sequence of Early Precambrian felsic and mafic volcanics intruded by granitoid plutons.

The gold mine at Starratt-Olsen was in operation between 1948 and 1956 and produced 164,000 oz of gold. It is in a SW-NW trending zone of deformation. Mineralization is largely contained in a felsic tuff.

200m north of the property is the New Faulkenham Mines shaft. Sunk in 1944/5 to 210m. Estimated reserve is 15000 tons grading 0.428 oz/ton gold. Selco Mining drilled a copper deposit (207o Cu) associated with an airborne EM anomaly, located in the eastern part of the property. Both gold and copper deposits are located in Figures 2 and 3 of this report.

1.2 Gravity Survey and Data ReductionThe surveying was conducted by this author assisted by Mr. John Williams. Surveying was done in the period March-24-31 2004. Measurements were taken at 100 m interval along north-trending lines at 200m spacing.240 gravity measurements were taken using a thermostatically controlled Sodin gravimeter; 286-T which rested on a 0.7 m. high tripod. Temperature setting was 25 degrees Celsius. The instrument has a sensitivity of 0.01 milligals (mgal).

A barometric system was used to determine relative station elevations. The method involves a digitally recording barometric monitor located at a base of operations and a "rover" unit (A.I.R barometric altimeter) located at each gravity measurement location. Maximum separation between base and rover was 2000 m. Measurements were also frequently tied to points of known elevation. Accuracy of this method is about 1 meter or 0.2 mgal.

1.2.1 Drift and Instrument Scale Correction.All gravity traverses commenced and ended by a reading at the survey base station. Instrument readings were converted to milligals using the instrument constant;

0.10062 mgal/instrument division

1.2.2 Latitude CorrectionThe data was corrected for northerly gravity increase; 0.7953 mgal/km.

1.2.3 Elevation CorrectionGravity decreases rapidly with distance from the centre of the earth. This decrease is alsopartly dependent on the density of the material underlying the gravity station.

The elevation correction may be written as + 0.3086 -0.041866 mgal/meter,where 6 is the density of the material between the gravity station and the minimumelevation of the survey. The selected density was 2.67 gm/cc.

For lake stations, the correction is 0.071 x water depth in meters.

1.2.4 Data CompilationA principal product of this survey is a digital recording of the reduced Bouguer gravity datain file GA2.dat that accompanies this report. It contains 5 columns of information;

1. station number2. UTM easting in meters, Zone 15, NAD833. UTM northing in meters Zone 15, NAD834. station elevation in meters,5. Bouguer gravity in milligals. O C*

O ^ O Terrain corrections were not applied to the data.

A map showing contoured Bouguer gravity and distribution of measurements in UTM co ordinates (NAD83), accompany this report as Figure 2. About 20 additional GSC measurements were used in the compilation.

2.1 Geological Interpretation and RecommendationsMost prominent feature exhibited in the gravity map (Ffigure 2) is a decrease in gravity from east to west of -6 milligals. This can be attributed to a decreasing thickness of greenstone covering the granite basement as we leave the axial part of the Red Lake synform.

Superimposed on this gradient are a number of secondary gravity features. A band-pass filter was applied to the gravity data in order to enhance these secondary features as opposed to regional gravity changes. The result is Figure 3.

Superposed on this gravity map are structures associated with apparent dislocation of gravity features. These include

* Three NNW trending fault zones; F1 and F2* Two NW-trending fault zones F3, F4 and F5.

Figure 4 is a segment of aeromagnetic map P1580 derived from an INPUT survey (1978) conducted by Questor for the OGS. Note the copper deposit associated with an observed conductor in the east part of the survey. The interpreted 5 gravity faults are traced on this map. Dislocation of magnetic zones across these fault lines corroborates much of the gravity iterpretation. Right-lateral dislocation across several of these faults is implied by the aeromagnetic map.

Wallace and Atkins (1993) show a number of NW-trending faults in OGS map P3196.

The position of these faults appear to explain the termination of gold mineralization trends at Starratt-Olsen and also at New Faulkenham.

Drilling to date has not tested the possibility that these dislocations actually host goldmineralization.It is recommended that two of the fracture zones be drill tested;

1. F5 immediately adjacent to the copper mineralization.2. F4 near the northern boundary of the permit3. F3 immediately west of the Faulkenham shaft.

Respectfully submitted,
