1. INTRODUCTION
At the request of Mr. Dave Saunders, prospector, a magnetometric and electromagnetic VLF surveys were carried on the Smiley Lake Property. An old grid was identified and a new grid was flagged. Geophysical surveys were carried out by Geosig Inc in May 2001. The magnetometric and VLF surveys covered the grid for a total of 13.6 km.
2. PROPERTY, LOCATION AND ACCESS
The property is located 80 km north of Thunder Bay. The Smiley Lake property is accessible by a logging road connecting to the Highway 527 around km 70. The property is located 15 km west of the main Highway.
3. CLAIMS
The geophysical surveys covered only a partial section of the property. Two ( 2 ) claims were covered by ground work. They are #1215553 and 1242418.
4. PERSONNEL AND INSTRUMENTATION
The Mag-VLF survey was carried out by Pierre Simoneau, geol. M.Sc.
The following instruments were used for the Mag-VLF survey:
- GSM-19WV field work, GEM System Inc., Richmond Hill, Ont. n/s 45369- GSM-19W base station, GEM System Inc., Richmond Hill, Ont. n/s 45349- GSM-19W mag sensor, GEM System Inc., Richmond Hill, Ont. n/s 4426556- GSM-19W mag sensor, GEM System Inc., Richmond Hill, Ont. n/s 4426558- GSM-19V(1) VLF sensor, GEM System Inc,. Richmond Hill, Ont.
The report was written by Pierre Simoneau, geol. M.Sc.
The maps and pseudo-sections were drawn and interpreted by Pierre Simoneau.
5. FIELD WORK AND PROCEDURE
The geophysical work was contracted to GEOSIG INC.
The magnetometer and the VLF surveys were done between May 13 and May 16, 2001
The grid extends in a SW-NE direction with NW-SE lines from 12+OOW to 8+OOE, with 200 m between each line. The main base line is at 0+00. The lines were flagged north and south of the baseline.
The Mag and VLF survey covered all the lines (except part of the baseline) for a total of 13.6 km. VLF stations (Cutler, Maine and Jim Creek (Seattle), Washington) were read at 12.5m separation, with detailed readings at 6.25m.
6. MAGNETOMETRIC SURVEY
6.1 Process of data and work
The measurements for the magnetic total field were taken in a mobile mag mode with a four (4) seconds sampling readings and label readings taken each 12.5 meters and some details at 6.25m.
A GSM-19WMV was used on the field with a GSM-19W base station with a 15 seconds registering readings period. The magnetic readings have been automatically corrected for diurnal variations when the data was dumped with a base value of 59100 gammas. The magnetometer system measures the value of the total magnetic field with a precision of 2.0 gammas.
6.2 Presentation of the results
Geophysical data was processed and presented on maps using the computer software programs; Geosoft and Microstation.
The magnetic results are presented on a profile map ( no. 3 ) and a total field contour map ( no. 4 ) at the metric scale of l : 2 500.
The property magnetic background is around 58 000 gammas with a maximum of 77984 gammas and a minimum of 40 000 gammas. The small high linear magnetic anomalies correspond to thin iron formations (usually less than 15m) and have a direction that generally crosscut the lines at an angle of 20 east of the baseline . At the southern end, the linear magnetic features a fold .
Most of the magnetic anomalies are just beside a VLF anomalie. This could be a result of pyrrhotite-pyrite or pyrite layers in oxide facies Iron Formations.
7. ELECTROMAGNETIC VLF SURVEY
7.1 Process of data and work
A GSM-19WMV was used on the field. The readings were taken at 12.5 meters spacing with some details at 6.25m. The VLF survey was made with two main stations - Cutler (NAA, 24,0 kHz) and Jim Creek-Seattle (NLK, 24,8 kHz).
7.2 Presentation of the results
The results are presented on profiles maps No. l and 2 at the metric scale of 1: 2,500.
The VLF survey detected seven (7) anomalies . A VLF anomaly is not usually a drilling target without other indicators. It is suggested to confirm a VLF anomaly with other geophysical method prior to drilling.
8. CONCLUSION
Reinterpreting the old surveys with the new one with what we say on the field make beleive that there is two syncline carrying conductors and narrow Iron Formations.
The geophysical campain gave interesting information about this property. Part of the property was covered by a previous VLF and MAG survey. This survey conducted with new instruments confirm the presence of 7 VLF. anomalies. These anomalies have an east-west trend.

GSM-19 overhauser magnetometer Features
Sensitivity = 0.02 nT
Absolute Accuracy * 0 .2 nT
Sample Rates up to 5 Hz
Low Power Consumption
General
"Overhauser" Once you experience it, you'll never go back to proton. Overhauser technology brings you sensitivities one to two orders of magnitude better than proton, yet in a light weight package. This is because the overhauser magnetometer consumes less power than proton magnetometer, allowing a lighter weight for batteries.
What is the Overhauser technique? The Overhauser sensor contains the electrons' fluid that has been added to a hydrogen rich in the form of "free radial". The resulting mixture yields a sensor with 5000 times gain in proton polarization. Since the Overhauser polarization effect does not require static magnetic fields, but uses radio frequency fields transparent to protons, measurement can be done concurrently with polarization. The result is a sensor with much greater sensitivity, that can be sampled much more rapidly than the standard proton sensor.
Overhauser magnetometer systems therefore maximize resolution while minimizing power consumption. Even with Walking Gradiometer systems, sampling at rates of once per second; Even in cold temperatures of - 40 zero degrees Celsius and greater, the internal rechargeable battery can still be relied on for a 10 hour day, or longer.
The GSM-19 Overhauser is a State-of-the-Art Magnetometer l VLF system and offers the data quality, reliability, and extensive list of capabilities, and options, that allow it to meet a very wide spectrum of applications.

Instrument Description
"Physical Overview"
The parts of the GSm-19 magnetometer/gradfometer are as follows :
The sensor is a dual coil type designed to reduce noise and improve gradient tolerance. The coils are elec trostatically shielded and contain a proton rich liquid in a pyrex bottle, which also acts as an RF resonator.
The sensor cable is coaxial, typically RG-58/U, up to 100m long.
The staff is made of strong aluminium tubing sections (plastic staff optional). This construction allows for a selection of sensor elevations above ground during surveys. For best precision the full staff length should be
used. Recommended sensor separation in gradiometer mode is one staff section (56cm from sensor axis to
sensor axis), although two or more sections are sometimes used for maximum sensivity.
The console contains all the electronic circuitry. It has a 16 keys keyboard, a 4 x 20 character alphanumeric display, and sensor and power/input/output connectors. The keyboard also serves as an ON-OFF switch.
The power/input/output connector also serves as RS232C input/output and optionally as analog output and/or contact closure triggering input.
The keyboard, front panel, and connectors are sealed i.e. the instrument can operate under rainy conditions.
The charger has 2 levels of charging, full and trickle, switching automatically from ont to another. Input is normally 110V 50/60HZ. Optionally, 12 VDC input can be provided.
The all-metal housing of the console guarantees excellent EMI protection.
"Software Version 4.0"
There are several major versions of software for the GSM-19. As of August 92, GEM Systems added a major software upgrade to its GSM-19 family, enhancing its capabilities. This new generation of software (version 4.0) has the following advantages:
Diurnal correction (reduction) with interpolation can be used in conjunction with other GSM-19 models with software version 4.0 (or special software for correction with an EDA Mag Base station). This allows the base
mag to run with longer cycle time Previous software could do interpolation only with fast GSM-19 types.
Memory filing system. Now 50 files can be stored in a directory, and mode of operation can be changed without erasing memory. With the software previous to version 4.0, only 1 file could be retained in memory, and this would be lost when modes of operation were switched.
Line and station numbers have been enlarged. Lines can now be 5 digits as opposed to 4 digits in previous software. Station numbers are now 7 digits as opposed to 6 in the previous software.

Standard Features
The GSM-19 magnetometer console features a real time graphic display of the current profile. In addition digital display of the current reading, current position, and warning messages are provided. The console design, with internal rechargeable battery pack, allows the unit to be completely sealed against the elements. With the built in heater for the display the GSM-19 magnetometer is ready to go wherever your surveys may take you.
Tuning is automatic worldwide, with provision for manual override. In high gradient conditions the GSM-19 magnetometer monitors the signal decay rate and displays a warning message when the gradient becomes too great. Filters for rejection of 50 or 60 Hz noise are provided.
Diurnal corrections may be done in traditional fashion with one magnetometer unit as a base station and a second unit used as the mobile field unit. At the end of the survey the two units are connected and the field unit creates a corrected data file (which still includes the raw data file) based on the temporal drift recorded by the base station.
As a standard feature GSM-19 magnetometer also offer the capability of making tie point measurements for automatic diurnal corrections. To use this feature the operator records a base value and then loops back to this point periodically during the survey to record another measurement, and thus build a file of the drift. In this way a single instrument may be used to make diurnal corrections.
The RS-232 port on the GSM-19 magnetometer will output data as it is collected. This allows interface to GPS loggers that will accept RS232 data. The standard GSM-19 magnetometer may be operated in a remote mode via computer. Memory storage is 512 K in the standard unit, and may be upgraded to 2 MB.
Grid coordinates are stored with either numeric or compass designations. A seven digit number may be used to designate lines and positions. Line and position spacing is entered so that with every reading the position may be automatically updated. An End of Line feature allows the next line to be quickly selected, plus changes the sign on the position spacing. If the previous line had been adding positions as the operator moved, then on the next line, positions will be subtracted as the operator moves. The operator may also easily manually enter his grid position for cases where gaps in the line are necessary.
'•Walking Mag Option"
The GSM-19 magnetometer is the first to offer the "Walking Mag" concept. The reason for this is the outstanding advantage the Overhauser sensor has in this application. With the "Walking Mag" option the operator may select a sample rate of up to two samples per second. At this rate Overhauser technology can still deliver a noise level that is quite acceptable, about 0.1 nT, and the lower power consumption means that a full day of surveying can still be done with just the internal rechargeable battery.
As shown in Figure 1 the near continuous data from the "Walking Mag" technique provides increased definition for any type of survey. For surveys with densely spaced grids, such as archaeological or environmental surveys, field productivity is markedly improved, typically by a factor of five.
When in the Walking Mag mode the operator still presets his line and station spacing. When a known station is passed a grid update key is pressed and the current reading is tagged with this station. Readings taken between these marked positions are then linearly interpolated for their grid position when data is transferred to a computer.
A further refinement of the Walking Mag concept is the Hip Chain Option. This option uses a hip chain to trigger the magnetometer to take a reading at discrete intervals. A Hip Chain consists of an optical encoder that records revolutions of a wheel wound with disposable cotton string. The string is tied off at the beginning of a line, and as the operator walks the string is pulled out, and the magnetometer is automatically triggered. With the Hip Chain option sample rates up to five samples per second are supported.
Omnidirectional VLF
3sur5 01-05-2213:51
magnetometer, GSM-19 fileVy/CI/Geosig/Gem/testLhtm
The GSM-19 VLF features a three coil design, with new larger coils in 1997, to achieve a non orientation capability with excellent sensitivity. Up to three VLF stations may be recorded, along with the magnetic reading, with the pressing of a single key.
As each VLF station is read the total field strength is displayed. This value may be used to determine if a station's signal is strong enough to obtain useful data. At the end of each reading the in phase, out of phase, and horizontal components are displayed and recorded for each station.
To determine what stations are available the Scan feature may be used. The entire VLF spectrum is scanned and stations with their corresponding signal strength are displayed. Automatic tilt compensation is provided up to ten degrees. Beyond this a warning message appears with display of the amount of tilt in each direction, enabling the operator to correct his position and take the reading again.
For Walking Mag applications a Walking VLF option is also available. With this option a single VLF station may be measured at sampling rates up to once per second. In this mode both magnetic and VLF readings may be collected at the one hertz rate.
Simultaneous Gradiometer
Many mining, environmental, and archaeological applications may benefit from using the gradient measurement. For near surface anomalies, generally twenty meters depth or less, the gradient anomaly will be larger, and narrower, than the total field anomaly. This permits the more accurate location of the target, and gives better sensitivity. The gradient measurement has the added value of being free from diurnal drift.
The most accurate gradient measurements are made when both sensors are polarized and measured at precisely the same time. In this way any slight movement of the sensor staff pole will not affect the reading. With the GSM-19 Gradiometer Option the pressing of a single key will initiate measurement of both the total field and gradient. Both readings are displayed and stored.
