Summary

In December, 2008, a 95 line km VTEM survey was flown over a 4 claim block CKidd Property') centered 3 km west northwest of the Kidd Creek mine. 7 Probable bedrock conductors within or on the edge of the claim block have been identified. Some of these conductors may have been drill tested in 1964. Others have not and some of these are suggested as possible VMS targets. A circular magnetic high within the claim block is a possible kimberlite pipe.

Report on a VTEM Survley Kidd Property, Timmins, Ontariorio

2090720 Ontario Inc.

On December 19, 2008, a helicopter EM and magnetic survey (VTEM) was flown over the Kidd Property centered 25 km north northwest of Timmins and just west of the Kidd Creek mine (figure 1). The survey was flown by Geotech for 2090720 Ontario Inc. The property includes claims 4211459 to 42 11462 (figure 2). The airborne survey covered a 10 km 2 area at 100 m. Total coverage was 95 line km.

Figure 1. VTEM survey, Kidd Property (from the Geotech report)

The results were presented at 1:10,000. All maps show EM anomaly centers. Map types are total magnetic intensity contours calculated vertical magnetic gradient contours dB/dt offset profiles B field offset profiles + total magnetic intensity BF26 (1.953 msec) contours

The airborne survey is described in appendix 1. Geotech picked 83 EM anomalies. 25 EM anomalies representing up to 7 bedrock conductors are within or on the edge of the Kidd Property.

12 drill holes from 1964 are within the claim block. Information on these drill holes from assessment records and on the Chance Zn-Pb-Ag deposit east of the claim block has been provided by 2090720 Ontario Inc. and is summarized in appendix 2.

The Chance deposit is within the area of the current survey. Its airborne expression and setting is described in appendix 3.

The property is within the area covered by a 2002 Megatem survey that is available as OGS Geophysical Data Set 1041. This survey is described in appendix 4.


..IVX

The VTEM results within the claim block are reviewed in light of the potential for VMS deposits and limited exploration in the 1960s. The 7 bedrock conductors within or on the edge of the claim block are described. Suggestions for further work on some of these conductors are made. A circular magnetic high that holds promise as a possible kimberlite pipe is discussed. The results of this work are presented on 3 maps at 1: 1 0,000. They are

1. TMI contours + VTEM EM anomaly centers + drill holes + conductor axis labels 2. CVG contours + VTEM EM anomaly centers + drill holes + conductor axis labels 3. VTEM and Megatem EM anomaly centers

The base map is as provided by Geotech. All maps show flight path and a UTM grid - NAD83, Z17N.

The Kidd Property is centered 3 km west northwest of the Kidd Creek mine (figure 3). The Kidd Creek Zn-Cu-Pb-Ag deposit was discovered in 1963 by Texas Gulf Sulphur by drilling a strong airborne electromagnetic anomaly. Since the commencement of mining in 1963, the Kidd



~vx

Creek deposit has produced 124.22 Mt grading 6.18 % Zn, 2.31 % Cu, O. 22% Pb and 87 glt Ag along with other elements such as Cd, Sn and Ge. With the development of D Mine, the extension of the deposit from the 6800 level to the 10,000 level, Kidd's reserves stand at approximately 23.66 Mt.

Figure 3. Kidd Property and Kidd Creek mine (oblique view provided by 2090720 Ontario Inc.)

Much of the land around the Kidd Creek deposit has been tightly held by many of the original owners since the discovery of the mine. Some of the land was explored in the early 1960's and has remained dormant since that time.

The Kidd Property was originally explored by Bunker Hill at the time of the Kidd Creek discovery. Records show that twelve (12) diamond drill holes were put into this block to test various EM and induced polarization anomalies. Assessment files that describe this work are summarized in appendix 2. The location, azimuth, inclination and length of drill holes, extracted from sketch maps in these assessment files, are listed in appendix 2.

Although lithologies are favourable for VMS deposits, massive sulphides were not found in any of these 12 drill holes. Some of the holes were explained by graphite. Geophysical methods of the time would have beeJl sorely tested by thick, conductive overburden. On average, the overburden in these 12 drill holes was 45 m thick. Range was 25 to 71 m. This is an ideal setting for VTEM.

The area was flown with Megatem in 2002. Although Megatem and VTEM have similar penetration, VTEM can locate steeply dipping thin sheet type conductors under 50 m of conductive overburden with surprising accuracy. In such settings, drill testing such targets based on VTEM alone is often possible.

The Chance deposit, a small, high grade VMS deposit just east of the Kidd Property, was discovered in the mid 1970s. Despite 40 m of conductive overburden, it is marked by a high conductance VTEM anomaly separate from a formational conductor 175 m to the west (appendix 3). It is in an area of a confused cluster of Megatem anomalies that is difficult to separate from those from the formational conductor.

2. Conductors

Within the claim block, EM anomaly strings and named bedrock conductors are concentrated within or on the edge of claims 4211459 (conductors C1 to C5) and 4211462 (conductors C6 and C7) . Conductors C1 to C5 and drill holes F1 and F4 to F9 are shown with the total magnetic intensity contours in figure 4. Conductors C6 and C7 and drill holes F2, F3, FlO, F11 and F12 are shown with total magnetic intensity contours in figure 5.

VTEM anomaly centers with a dip indication (central orange cross) represent steeply dipping thin sheet conductors. In most cases, the anomaly center should be within metres of the leading or upper edge of the conductor. Conductor form and location are more speculative under VTEM anomalies with no dip indication. In the description of each conductor that follows, VTEM anomaly centers are identified by flight line and ID (appendix 1, table 3).

Figure 4. TMI with conductor labels and drilling, north part

C1 : 1000A, 10108, 1020A

This conductor is largely north of the claim block and is open to the northwest. It sits on the northeast flank of a 50 nT magnetic high. Based on amplitude and clarity, the best of the set is 1010B - it suggests a thin sheet conductor with an intermediate dip to the northeast at an estimated depth of 45 m. Conductance is very high (49.1 S dB/dt).



.. vx C2 : 1040B, 1050A, 1060C, 1070B

C2 is a 300 m long conductor that crosses the northeast corner of claim 4211459. All 4 EM anomalies suggest a vertical thin sheet conductor. In terms of EM anomaly amplitude, clarity and quality, 1050A is the best of the set. Based on peak separation, the depth is 40 m. Conductance is high (43.2 S dB/dt). C2 has no clear magnetic expression.

C3 : 1040A, 1050B

C3 is made up of two positive EM peaks with little indication of conductor form, location or depth. C3 may be over the down dip side of a northwest extension to C5. Alternatively, 1040A and 1050B are due to particularly thick or conductive overburden. Over most of the survey, elevated early time EM channels are consistent with some thickness of conductive overburden. Strong bedrock conductors that are not steeply dipping thin sheets are recognizable only at late times. This gets difficult in that grey area where overburden conductivity and conductor conductance get too close.

C4: 1060B,1070C, 1080B,1090B, 1100B, 1110B

C4 is a 500 m long conductor axis in a mixed magnetic setting. All EM anomalies suggest a near vertical thin sheet conductor. The best ofthe set are 1070C and 10808. Estimated depths are 55 m (1070C) and 70 m (1080B). dB/dt conductance estimates are 32.5 S (1070C) and 24.6 S (1080B). Drill holes F7, F8 and F9 as plotted would not have intersected C4. If drill testing C4, a drill set 75 m northeast of 1070C and inclined to the southwest might be considered. Collar at 469636 e, 5394414 n, azimuth 225°, inclination -50°, length to 150 m.

C5: 1060A, 10700, 1080A, 1090C, 1100A, 1110C, 1120A, 1130B, 1140B

This string of 9 VTEM anomaly centers has been grouped into one conductor axis but it might better be separated into two short conductors, each associated with its own magnetic high. The connecting EM anomalies 1080A and 1090C are nondescript weak positive peaks of an uncertain cause.

The northwest part of C5 is defined by 1060A and 1070D on the western edge of a 135 nT magnetic high. Drill holes Fl, F4, F5 and F6 as plotted would not have intersected C5. 1060A suggests a near vertical thin sheet conductor at 30 m depth. 1070D suggests a conductor with an intermediate to steep dip to the northeast at 45 m depth. Conductance estimates are not high (12.3 and 17.6 S). 1070D has the better magnetic expression. If drill testing this part of C5, a drill 75 m northeast of 1070D and inclined to the southwest might be considered. Collar at 469333 e, 5394108 n, azimuth 225°, inclination -50°, length to 150 m.

The best EM/magnetic anomalies of those that make up the southwest part of C5 are 1100A and 1110C. Both are at or near the peak of a 115 nT magnetic high of similar dimensions. The conductor is near vertical and is at an estimated depth of 70 m (1100C). dB/dt conductance estimates are moderate to strong -15.7 S (1110C) and 23.3 S (1100A). Strike length and magnetic setting make this one of the better airborne targets in the claim block. If drill testing this part of C5, the drill might be set 100 m northeast of the mid point between 1100A and 1110C. Collar at 469718 e, 5394000 n, azimuth 225°, inclination -50°, length to 200 m. The proposed collar is within a few metres of the claim boundary as taken from the MNDM claimap3 website.

Figure 5. TMI with conductor labels and drilling, south part

C6: 1170A, 1180B, 1190B, 1200B, 1210A, 1220B, 1230C, 1240B, 1250B, 1260C, 1270C, 1280C, T1510A

C6 is a 1 km long conductor open to the southeast. It is made up ofVTEM anomalies that range from very weak in the north to strong in the south. C6 has no clear magnetic expression. Its southern part is east of a 75 nT magnetic high. The conductor appears to be at depth - the depth estimate for 1240B is over 100 m. Bunker Hill drill holes FlO, Fll and F12 as plotted may have intersected C6 near the end of hole. Strike length and a neutral magnetic setting make this a second priority airborne target.

C7 : 1270B, 1280D

C7 is made up of two positive EM peaks with little indication of conductor form, location or depth. As with C3, these may be overburden anomalies.

3. Possible Kimberlite Pipe

The circular 50 nT magnetic high on the border between claims 4211460 and 4211461 (figure 6) might be considered as representing a possible kimberlite pipe. From the vertical gradient, the apparent diameter of the source is 200 m. As with other circular magnetic highs in the region, it is covered by Keating kimberlite coefficient anomalies (appendix 4). The target is

2090720 Ontario Inc. JVX 9-21


~vx

under a swampy area of similar dimensions. Early time EM levels over the target are at least as high as anywhere else in the survey - 50 m of overburden is likely. The target center is near 468900 e, 5393290 n.

Figure 6. TMI, center part

4. Conclusions

Results from a recent 95 line km VTEM survey over the Kidd Property have been reviewed. 7 bedrock conductors within or on the edge of the claim block have been identified. Drill holes from 1964 may have come close to some of these conductors but uncertainties in location leave this largely unresolved. Geophysical methods of the time would have been tested by 40 to 50 m of overburden.

Of the 7 named conductors, the two short conductors that make up C5 may be the most interesting. Despite modest conductance estimates, they have the best magnetic setting. Suggestions for drill testing both are made.

A circular magnetic high within the claim block might be considered as a possible kimberlite pipe.

One target outside the claim block deserves mention. It is 1190A at the center of a 200 m long, east/west trending conductor southwest of the claim block. 1190A represents a thin sheet type conductor with a steep dip to the southwest. The estimated depth is less than 25 m. The conductor has a coincident 15 nT magnetic high. The dB/dt conductance estimate is 20.5 S.

Appendix 1 : VTEM Survey

A helicopter EM (VTEM) and magnetic survey was flown by Geotech for 2090720 Ontario Inc. over a 10 km2 area centered 25 km north northwest of Timmins and just west of the Kidd Creek mine (figure 1). The survey area includes claims 4211459 to 4211462. The survey was flown in December, 2008. The Geotech report is dated February, 2009. The Geotech job number is 8258. Total production was 95 km on northeast lines at 100 m. The results were presented at 1:10,000. Map types are

total magnetic intensity dB/dt offset profiles B field offset profiles + total magnetic intensity VTEM BF25 (1.641 msec)

All maps show flight path. a topographic base and claim fabric taken from the MNDM claimap3 website.

Figure 1. Flight path (figure 2 from the Geotech report)

Following delivery of the report, maps and databases from Geotech. they were asked to pick EM anomalies representing probable bedrock conductors and to add annotated EM anomalies to the maps and database. A revised set of maps were provided. Scale. layout. flight path. topographic base and claim fabric are the same as in the original map set. Map types are

The power line monitor shows nothing over the claim block. There are power line responses in the eastern part ofthe survey - at the ends of lines 1210 to 1280. UTM coordinates of the center of the power line response and a nearby EM anomaly are listed in table 2. As there is no increase in EM sensor terrain clearance over these power line responses, the power line (if there) is local. The power




line responses are often asymmetric and of the same shape as the nearby VTEM EM anomaly. All of this suggests this is not a power line but a formational conductor energized at 60 Hz from grounded electrical noise from the Kidd Creek mine.

Table 2. Power line responses

Geotech picked 83 EM anomalies . There are 2 types -

- a single positive EM peak that may represent a flat lying to intermediate dipping conductor (dip < 60°), the top of a broad conductor or any number of irregular conductors. Confidence in conductor form, location and depth is usually low. These are type K for 'thick' sheet in table 3. The EM anomaly center is at the EM peak. Conductance estimates and amplitudes are taken at the EM peak. 13 of th e 83 EM anomaly centers represent 'th ick' conductors.

- a double peak EM anomaly that may represent a steeply dipping thin sheet conductor. These are type N for 'thin' sheet in table 3. The EM anomaly center is at the leading or upper edge of the conductor. Conductance estimates and amplitudes are taken at the stronger EM peak. Plotted EM anomaly centers show dip sense. Confidence in conductor location, form and depth is usually high. 70 of the 83 EM anomaly centers represent steeply dipping thin sheet type conductors. Of these, 8 are shown as vertical.

the dBjdt decay (CondSF) is 23.0 S. Range is 6.1 to 59.1 S. The average conductance estimate from the B field decay (CondBF) is 37.2 S. Range is 6.8 to 91.8 S. [t is common for CondBF to be about twice CondSF. Anything over 20 S is usually considered strong. Anything over 50 S is very strong and is often of immediate exploration interest.

The average BF26xl00 is 5.1 pVmsecjAm4. Range is 0.1 to 29.3 pVmsecjAm4. Shallow, strong flat lying or flat topped conductors should generate BF26xl00 peaks of more than 250 where shallow means 10 m or less and strong means a conductance of at least 20 S. Lower peak BF26 values usually mean greater depth of burial.

Amplitudes are as recorded - no attempt has been made to separate the EM responses from the conductor and from the overburden. Independent of geometrical attenuation, thick conductive overburden tends to reduce overall time constants and may lead to lower conductance estimates.

Table 3. EM anomalies

As part of the EM anomaly picking, Geotech amended the database to show the last channels of 4 used to calculate the time constant (NchanSF, NchanBF), the time constants (TAUsf, TAUbf), the conductance estimate taken from the time constant (CONDsf, CONDbf), an anomaly channel (anoms) and the BF26 amplitude. The time constant calculation is described in an appendix to the Geotech report. Geosoft databases may be opened and EM channels displayed as profiles using the freely available Geosoft viewer.



Appendix 2 : Exploration History and Drilling

Claims 4211459, 4211460 and 4211463 were explored by Bunker Hill Extension Mines Ltd. shortly after the Kidd Creek discovery in 1963. Assessment files show twelve (12) drill holes from 1964 to test various EM and induced polarization anomalies in these claims. There are drill logs for the first three holes (B-1, B-2 and B-3). The rest of the holes were drilled by Bunker Hill but do not appear to have been reported in the Bunker Hill assessment file (file T -805). Drill holes 4 to 12 have been taken from Hollinger Mines assessment file compilation maps (Files T -1790 and T-3646) with limited information and no logs. Assessmentfiles are T-805 from Bunker Hill (AFRI files 42A11NW0573 and 42A11NW0987), T-1760 from Hollinger Mines (AFRI files 42AllNW0559 and 42A11NW0560) and T-3546 from Homestake.

Kevin Filo of 2090720 Ontario Inc. has identified the 12 drill holes by Bunker Hill Extension Mines Ltd. from various sketch maps in these assessment files and has provided best estimates of locations, azimuths, inclinations and lengths. His findings are summarized in table 1. His notes for each hole follow.

In table 1, the hole number (F1 to F12) has been assigned by Kevin Filo. Ref. is the hole number as shown in sketch maps from Bunker Hill (B-1, B-2, B-3, B-4, B-10, B?) or Hollinger Mines (H-1 to H-14). UTM coordinates are NAD83, Z17N. Lengths are in metres. Dip information is not available for drill holes taken from Hollinger maps. For these holes, (H-1 to H-14), lengths are as project to surface. Lengths if the hole was inclined at -500 are shown in brackets.

'ov' in table 1 is the overburden thickness in metres as shown on sketch maps. These numbers are consistent with overburden thicknesses from drill logs for B-1, B-2 and B-3.

Ref.Pt. in table 1 is the sketch map reference point from which all drill holes are located. Reference Point A is the No.1 Post of claim 4211461(51/2 5W1/4 Con VI Lot 8) at 468919 e 5393876 n. Reference point B is the No.3 Post of claim 4211462(51/2 5W1/4 Con V Lot 7) at 469715 e, 5392263 n.

Summary

- holes Fl, F4, FS and F6 are all drilled in the same area. These holes appear to have evaluated the one conductor that they are clustered around. The cause of this conductor was graphite bands. The holes intersected felsic volcanics which have an important relationship to VMS deposits like Kidd Creek and Chance. Some minor chalcopyrite was noted in Fl in a small rhyolitic section of the hole.

- holes F2 and F3 were drilled to evaluate induced polarization targets. These holes failed to explain the cause of the IP anomalies. The holes did intersect some dacite suggesting the presence of some intermediate to felsic volcanics in this portion of the property as well.

- holes F7 and F9. Limited information from the Hollinger compilation map shows these holes intersected some graphite.

- hole F8 does not appear to have intersected any conductor.

- holes FlO, Fll and F12 intersected some graphite according to limited information.

From Kevin Filo - 'Limited drill data suggests a favorable lithology for VMS deposits on the property. From the various orientations of drilling it is evident that there is likely some folding on this property and the actual strike orientation ofthe geology may be somewhat complicated.'



Appendix 3 : The Chalnce VMS Deposit

In the mid 1970s, a small, high grade lead-zine-silver deposit was discovered by Chance Mining and Exploration 2 km northwest of the Kidd Creek mine. The Chance deposit consists of two closely spaced sulphide lenses that are near vertical and under about 40 m of overburden. The lenses reside in a zone that is 80 m long, 5 m wide and runs to a depth of about 250 m. In 1999, Falconbridge calculated an inferred resource estimate of 176,900 tonnes grading 12.8% Zinc, 3.24% Lead and 178 g/t Ag.

In 1999 Opawica Explorations Inc. entered into an option and joint venture agreement with Falconbridge Limited (now Xstrata PLC) on the Chance property. The property includes 51/2, Lot 6, Conc 6 and N1/2, Lot 6, Conc 5 (figure 1).

From figure 1, the deposit is near the southern boundary of lease claim P56133. From this, the center of the deposit is estimated at 47 1140 e, 5393853 n. From a sketch map in the July 19, 1985 issue of the Northern Miner, the deposit is estimated to be centered at 470980 e, 5393939 n. From this same sketch, the deposit is 180 m east of a north northwest trending band of argillites/greywacke.

Both estimates for the position of the Chance deposit are within the area of the VTEM survey and near the northeast end ofline 1210. The average estimate of position, 471060 e, 5393896 n, is 25 m northwest ofVTEM line 1210 at closest approach.

Figure 1. From www.opawica.com

The Chance deposit (at 47 1060 e, 5393896 n) is shown as a green cross on the magnetic map from the VTEM survey (figure 2). The nearby VTEM EM anomaly center (1210B) represents what Geotech suggests is a thin sheet conductor with a steep dip to the southwest. Conductance estimates are very high (59.1 5 dB/dt, 82.3 5 B).



Appendix 3. The Chance VMS Deposit

The EM profiles suggest another conductor 175 m to the southwest. This was not picked by Geotech but would be the logical continuation of a formational conductor with a steep dip to the northwest. A power line response centered 178 m southwest of 1210B may represent the formational conductor energized by grounded 60 Hz noise from the Kidd Creek mine.

Appendix 4 : 2002 Megatem Survey

The area was surveyed with Megatem in February/March, 2002 as part of larger regional survey COGS MNDM GDS 1041, 'Timmins Megatem'). This survey covered some 1500 km2 (figure 1) with a survey total of 11,173 line km. The Kidd Property is in block Ai (figure 2).

Part of the map showing Megatem and VTEM EM anomaly centers is shown in figure 6. The large number of Megatem EM anomaly centers is because this area was flown east/west at 125 m and north/south at 200 m. Annotations on the Megatem EM anomaly centers are written parallel with the flight path.

The comparison between the two EM anomaly sets over what Geotech suggests are strong, steeply dipping thin sheet conductors is good. There is the usual scatter of up to ± 50 m of the Megatem EM anomalies relative to the conductor axes as represented by the VTEM EM anomalies. There are a number of weak Megatem EM anomalies with no VTEM picks. There are a few strong EM anomalies of each type with no picks of the other type. In this area, Megatem and VTEM appear to have equal penetration. VTEM provides a more accurate placement of conductor axes and gives dip. The VTEM results are easier to read.
