Summary

Spectral IP/resistivity and magnetic surveys were done on the Tyko property –

2011 grid 29 km southeast of Manitouwadge, Ontario. The field work was done from

November 22, 2011 to January 18, 2012. Total production was 29,775 m IP/resistivity

and 56,385 m magnetics. The results have been presented on 5 maps at 1:5,000 and

20 stacked pseudosections at 1:2,500. One of the maps shows IP anomaly centers

over the magnetics with drill holes.

The Tyko and RJ Ni-Cu-PGE occurrences are well marked by moderate to strong

IP anomalies that suggest the occurrences are depth limited. The Tyko occurrence has

no clear resistivity or magnetic expression. The larger RJ occurrence is associated with

a resistivity low and high magnetic relief. The 2D IP inversion results suggest the RJ

occurrence continues to the east-southeast at depth.

Spectral IP/Resistivity and Magnetic Surveys Tyko Property – 2011 Grid, Manitouwadge Area, Ontario

Tyko Resources Inc. Spectral IP/resistivity and magnetic surveys were done on the Tyko property – 2011 grid,

centered 29 km southeast of Manitouwadge or 63 km east northeast of Marathon, Ontario. The work was done for Tyko Resources Inc. by JVX Ltd. under JVX job number 11-99. The field work was done from November 22, 2011 to January 18, 2012. Total production was 29,775 m IP/resistivity and 56,385 m magnetics.

Figure 1. Regional location map

The grid covers all or parts of claims 3012936, 3012937, 3012938, 4203376, 4203377, 4203385 and 4203397 registered to Tyko Resources Inc. The grid is made up of 22 north northeast lines at 100 m spacing (3300W to 5400W) and one tie line at 10000N. The maximum station range is 9225N to 12000N. The grid is bounded by Pickle Lake on the northwest and Peanut Lake to the southeast. Tyko Lake is just south of the property. Magnetic readings were taken every 5 m. IP/resistivity surveys were done in time domain with a pole-dipole combination array. The moving current electrode was advanced in 25 m steps. In general, 8 receiver dipoles were set out at each current electrode position. The first 2 or 3 dipoles were 25 m long. The last 5 or 6 dipoles were 50 m long. The moving current electrode was always grid north of the potential electrodes.

The results are presented on maps at 1:5,000 and stacked pseudosections at 1:2,500. The maps include total magnetic intensity, n=1 Mx chargeability, n=1 apparent resistivity and 2 compilation maps - IP anomaly centers over magnetics and IP anomalies over n=1 resistivities. Compilation maps show 2006 and 2007 drill holes provided by Tyko Resources. The stacked pseudosections include 2D inversion results for Mx chargeability and apparent resistivity.

Production summaries, grid registration, instrumentation and data processing are described in appendix 1. Weekly field production reports are reproduced in appendix 2. IP anomaly listings are in appendix 3. Instrument specification sheets are attached. The results of the survey are discussed below. 1. Presentation The results of the surveys are presented in 5 maps at 1:5,000 and 20 stacked pseudosections at 1:2,500. All maps show land tenure from the MNDMF claimap3 website and drainage from NRCAN geogratis.ca. A UTM grid (NAD83, Z16N) and latitude / longitude co-ordinates have been added. The 1:5,000 map sheet area is 3.25 x 3.6 km (603660 to 606910 e, 5419840 to 5423445 n, NAD83, Z16N). Map types are

2. Background Alan Aubut’s 43-101 ICI report indicates that, prospecting resulted in the discovery of the Tyko

Cu-Ni-PGE showing in 1999. Freewest Resources optioned the property, flew an Aeroquest AeroTEM survey and did two sets of ground IP surveys. Prospecting resulted in the discovery of the nearby RJ Cu-Ni-PGE showing in 2005. IP surveys and diamond drilling (13 holes, total 2230 m) by North American Palladium of the Tyko and RJ occurrences followed. The best intersection was 1.2% Ni and 0.506% Cu over 2 m in hole TK06-004.

The 2006 report from the North American Palladium states that:

“The Tyko property sits within an area that has seen very little government mapping or historic exploration. Regional-scale mapping indicated that the rocks in the area were predominantly granitic. Prospecting and mapping indicated that the granites contain numerous mafic to ultramafic xenoliths or fragments, some of which are mineralized.

Sulphide mineralization within these ultramafic fragments varies from fine-grained disseminated to coarse grained blebby. Macroscopically, the sulphides consist mostly of pyrrhotite and chalcopyrite with lesser pyrite. A second group of xenoliths are referred to simply as amphibolites. These rocks are usually barren except for minor amounts of pyrite. The mafic-ultramafic body intersected at the RJ showing is quite large and may be considered an intrusive body as opposed to a large “raft” in the granites.”

Figure 3. n=1 Mx chargeability

The 13 North American Palladium drill holes are listed in table 1 and plotted with the 2011 grid in figure 4. The Tyko occurrence is in the extreme south part of the grid and in the area of holes TK06-001 and TK06-002. The RJ occurrence is in the west central part of the grid and in the area of holes TK06-003 to TK06-005, TK07-001, TK07-002, TK07-003, TK07-005 and TK07-006. Some prominent sulphide intersections are listed in table 1. Drill log descriptions of the sulphides include disseminated, blebby, net-textured, stringer and semi-massive net-textured. The section of interest is named mineralized hornblendite. In the drill log, the northing for hole TK07-010 is listed as 5422155. From maps provided by Tyko Resources, this should be 5421155.

The 2011 grid is within an area flown for Tyko Resources in early 2011 with AeroTEM with 100 m lines at 350°. Total coverage was 751 km. The results were presented on maps of TMI, Zoff channel 0 at .0384 msec and Zoff offset profiles at 1:20,000. The magnetics map is shown in figure 5. All maps show EM anomaly centers. All EM anomaly centers represent surficial conductors - lake bottom sediments. No bedrock conductors were detected. This is consistent with results from earlier airborne surveys.

In order to better highlight any magnetic highs associated with the Tyko and RJ occurrences, Aeroquest was asked to remove the effects of the northeast trending mafic dikes from the TMI grid. The results were partially successful. Part of the problem in any 2D filtering of the airborne magnetics is the loss of resolution that comes with an average sensor terrain clearance more than 80 m. Short wavelength features seen in the ground survey become blurred at the higher terrain clearance.

3. Survey Results – Overall Statistics The average of all 11,250 total magnetic intensity readings is 56,872 nT. Range is 56,580 to 58,113. The reference geomagnetic field for this place (48.94° north, 85.56° west, 368 m amsl) and time is given by amplitude 57,023 nT, inclination 74.5° and declination 7.3° west of north.

Overall statistics for all Mx chargeabilities, apparent resistivities and for those from the first dipole only are listed in table 2. Also shown are the percentages of chargeabilities in 4 ranges. Units are mV/V for chargeability and ohm.m for apparent resistivity. A total of 7,794 dipoles were read.

As with most surveys in this type of terrain, background levels for Mx are ≤ 5 mV/V. 24% of all Mx values are in the range of 5 to 10 mV/V, the conventional range for ‘weak’ IP anomalies. A moderate IP anomaly normally means peak Mx values of 10 to 20 mV/V and strong means peak Mx values more than 20 mV/V. Under these criteria, less than 2 % of all chargeabilities are moderately or strongly anomalous. In the absence of bedrock conductors, most crystalline rock has a resistivity of more than 50,000 ohm.m. Sea water has a resistivity of around 1 ohm.m. Overburden resistivities in the Canadian Shield are commonly in the range of 50 to 200 ohm.m. In the absence of bedrock conductors, most variations in apparent resistivity are due to variations in the conductivity and thickness of the overburden. Most soil and bedrock conductivities are determined by water content and ground water conductivity. The distribution of n=1 apparent resistivities is shown in figure 6.

Figure 6. Distribution of n=1 apparent resistivities

n=1 resistivities more than 10,000 ohm.m (45%) usually means some outcrop and a prospecting history. n=1 resistivities in the range of 2,000 to 10,000 ohm.m (29%) often means access to bedrock may be possible by back hoe stripping. In the absence of bedrock conductors, n=1 resistivities less than 1,000 ohm.m (16%) usually mean no outcrop, some thickness of overburden and some reduction in the amplitude of IP anomalies from any underlying chargeable bodies.

More than 96% of the measured IP decays are of sufficient amplitude and quality to generate spectral parameters with a fit value of less than 5%. 80% is considered a good performance number for most surveys. Anything more than 90% is excellent. 4. IP anomalies IP anomalies that are thought to represent a discrete body of chargeable material have been picked from the pseudosections. The location and extent of the anomaly centre-top, IP anomaly amplitude, dipole number of the centre-top, spectral IP features and the resistivity setting and expression are taken from the measured pseudosections. IP anomalies are classed as weak, moderate or strong. IP anomaly listings are in appendix 3.

A total of 17 IP anomalies have been picked. 7 are classed as weak. 5 are moderate and 5 are strong.

all IP anomalies have centre-tops in the first dipole. These are all shallow chargeable bodies with estimated depths to top less than 20 m. No IP anomalies are seen in the measured sections at depth.

only 2 IP anomalies have an associated resistivity high. 8 have an associated resistivity low. 7 have no clear resistivity expression.

In areas of little or no overburden, Mx chargeabilities are often in the range of 5 to 7 mV/V. These are considered background values and characteristic of bedrock with little or no sulphides. These areas are not identified as weak IP anomalies unless they appear in a confined IP anomaly form. 5. Compilation Map

The 1:5,000 compilation maps shows IP anomalies and the 13 North American Palladium drill holes. There are 2 compilation maps – one with IP anomalies over the magnetics and one with IP anomalies over the n=1 apparent resistivity. The IP anomalies are shown as coloured squares. They are red for strong, orange for moderate and yellow weak. The anomaly ID is shown on the left side of the coloured squares.

6. Discussion The Tyko and RJ occurrences are well marked by moderate to strong IP anomalies with centre-tops in the first dipole. Most of the IP anomalies are consistent with depth limited chargeable bodies with depth extents from 50 to 200 m. The relationship between the low resistivities over the RJ occurrence and the mineralization is unclear. The strongest / shallowest parts of the Tyko and RJ IP anomaly sets are well sampled by the North American Palladium drill holes. Two weak IP anomalies away from the Tyko and RJ occurrences have been picked. Both are poorly defined, shallow features of little geophysical interest. They may be no more than high background chargeabilities isolated by overburden variations.

The Tyko occurrence and its host has no clear magnetic expression. Magnetic relief over the RJ occurrence is often high but the relationship between the occurrence and the magnetics is not clear (figure 7). Dighem and AeroTEM surveys have not identified any bedrock conductors on the property.

J V X


Stacked 2D Mx chargeability inversions for lines 5300W to 4700W in the area of the RJ occurrence (10000N to 15000N) are shown in figure 8. These affirm the strongest / shallowest IP anomaly is at 10200N to 10300N on line 5000W. There are 3 NAP drill holes in this line segment. They also confirm the depth limited nature of the IP zone.

New information from these sections is the implication that mineralization may be found at depths of 75 m under station 10175N on line 4700W. The inversion results suggest the RJ zone continues at depth east and south of its shallowest parts. More drilling into the inverted IP highs on lines 4800W and 4700W might be considered – with due regard for all of the uncertainties that accompany ‘inversion’.

NAP drilling focussed on the strongest IP anomalies and these are almost always the shallowest parts of the target. Inversion should correct the reduction in IP anomaly amplitude from targets at depth. Inverted IP highs at depth may or may not be real – they are best judged in parallel with the measured IP results.

7. Conclusions Spectral IP/resistivity and magnetic surveys were done on the Tyko property – 2011 grid,

Total production was 29,775 m IP/resistivity and 56,385 m magnetics. The results have been presented on 5 maps at 1:5,000 and 20 stacked pseudo sections at 1:2,500. Compilation maps show IP anomalies and drill holes over the magnetics and over n=1 apparent resistivity.

The Tyko and RJ occurrences are well marked by moderate to strong shallow IP anomalies of limited depth extent. Inversion suggests the RJ showing continues at depth east and south of its shallowest parts. Parts of these inverted IP highs are untested and may be drill targets. Allowance should be made for the possibility that some of these inverted IP highs are not real. Ian Johnson, Ph.D., P.Eng. Blaine Webster, B.Sc., P. Geo. February 24, 2012

For the IP/resistivity survey, coverage is measured from the station of the first moving current electrode to the station of the last potential electrode (ideal grid). For the magnetic survey, coverage is measured from the first to last station (ideal grid). Magnetic readings were taken every 5 m. IP/resistivity surveys were done in time domain with a pole-dipole combination array with the first 2 or 3 dipoles 25 m long and the last 6 or 5 dipoles 50 m long. Psuedosection plot point depths are from 19 to 175 m. The moving current electrode was always grid north of the potential electrodes.

Personnel The field work was done by JVX personnel Scott Mortson (party chief), senior geophysicist Dennis Palos and assistants Jeff Spiers, Jeff Boettcher, Yaroslav Kubacek, Michel Begin, Dan Kelly, Claude Robert and Brad Jackson. Data processing was handled by Hasnein Jeraj at the JVX office in Richmond Hill, Ontario. Grid The grid covers all or parts of claims 3012936, 3012937, 3012938, 4203376, 4203377, 4203385 and 4203397 registered to Tyko Resources Inc. The grid is made up of 22 north northwest lines at 100 m and one tie line at 10000N. The maximum station range is 9225N to 12000N. Grid registration is based on UTM coordinates collected with a hand held GPS receiver at 99 points at various locations on the grid, including line ends. The average separation between GPS control points is 705 m. The full set of GPS control points is listed in table 1. The grid is drawn by interpolation or extrapolation from these control points. The full grid is shown in grey in figure 1. Line segments with IP/resistivity are shown in black. Lake names in figure 1 are Pickle (northwest), Peanut (southeast) and Tyko (south).

Instrumentation Magnetometer

Gem Systems GSM-19, SN 6072060, 7052356 and 7082476

When set up for mobile readings, the GSM-19 magnetometer records line, station, total magnetic intensity and time. When operating as a base station, it records total magnetic intensity and time. Total magnetic intensity is measured to 0.01 nT. The base station was set to take a reading every 10 seconds. Specification sheets are attached. IP/resistivity

Scintrex IPR-12 time domain IP/resistivity receiver, SN 950248 GDD TXII – 1800W-2400V time domain transmitter, SN TX#258 Honda 3000 watt MG set. SN 1900-827-0000

For each potential electrode pair, the IPR12 measures the primary voltage (Vp) and the ratio of secondary to primary voltages (Vs/Vp) at 11 points on the IP decay (2 second current pulse). These 11 points are labeled M4 to M14. There is the option for an additional user defined slice (Mx). Units are



5

millivolts for Vp and milliVolts/Volt for M4 to M14 and Mx. Settings are

Vp : 200 to 1600 msec M4 centered at 60 msec (50 to 70) M5 centered at 90 msec (70 to 110) M6 centered at 130 msec (110 to 150) M7 centered at 190 msec (150 to 230) M8 centered at 270 msec (230 to 310) M9 centered at 380 msec (310 to 450) M10 centered at 520 msec (450 to 590) M11 centered at 705 msec (590 to 820) M12 centered at 935 msec (820 to 1050) M13 centered at 1230 msec (1050 to 1410) M14 centered at 1590 msec (1410 to 1770) Mx centered at 870 msec (690 to 1050)

The apparent resistivity is calculated from Vp, the transmitted current and the appropriate geometric or K factors. M4 to M14 define the IP decay curve. The Mx slice is commonly presented in pseudosections and maps.

JVX has chosen the above settings for Mx in order to better reflect an IP measurement from the older Scintrex IPR11 time domain receiver. In IPR11 surveys from the 1980s, this chargeability window was most often plotted and experience gained is based in part on this measurement.

The IPR12 also calculates the theoretical decay that best fits the measured decay. The theoretical decay is based on the Cole-Cole impedance model applied in the 1970s. The fit is based on a set of theoretical master curves with restrictions that limit the value of the calculation. JVX uses a different method to calculate impedance parameters (see below).

The Instrumentation GDD Inc. GDD TXII 1800 time domain IP transmitter operates off 120V output from a 3000 watt motor generator. Output is current stabilized from 150 to 2400 volt taps. The maximum current is 10 amps. Current and circuit resistance are displayed in digital form.

Data Processing and Presentation Grid The grid is drawn by interpolation or extrapolation from a set of 99 GPS control points – 99 widely separated line/stations with UTM coordinates from a hand held GPS receiver.

Base Map Land tenure has been downloaded as *.shp files from the MNDMF claimap3 website. Lakes,

rivers and roads have been downloaded as 1:50,000 *.shp files from geogratis.ca (Earth Sciences Sector of Natural Resources Canada). There are minor differences in topographic elements from federal and provincial sources.

Magnetics At the end of every survey day, data from the mobile and base station magnetometers are dumped to a PC. Output from both magnetometers are text files labelled by date and the operator’s name or ‘base’. Data dumps from the mobile unit show line/station, total magnetic intensity (nT) and time (decimal hours). Data dumps for the base unit show time and total magnetic intensity. Subsequent processing steps normally are

1. Apply base station corrections to the mobile data. Corrected total magnetic intensity values are appended to the mobile files and renamed as *_corr files. Bad data or repeat values are removed.

2. Move the contents of the files containing the corrected total magnetic intensity into a Geosoft database (*.gob).

Colour + line contour maps of the corrected total magnetic intensity are generated from the database using Geosoft Montaj. Random gridding with a 7.5 m grid cell is used.

In this job, the base station was not set up properly. The base station record could not be synchronized with the mobile records and could not be used for the diurnal correction. A low pass filter of the uncorrected total magnetic intensity grid was used as a substitute.

Because orientation is close to the survey grid, north/south magnetic features were poorly represented in the TMI grid. A further process of trend reinforcement was used to better show these features.

IP/Resistivity At the end of every survey day, the IP/resistivity data are dumped from the IPR12 to a PC.

Output is a text file with the date as the file name. Raw data from each survey line are collected in text files with the line number as the file name. The data are checked for quality and quantity. The data are archived for transfer to JVX Ltd. in Richmond Hill.

Office data processing is based largely on Geosoft Oasis Montaj v6.3 (www.geosoft.com). Impedance modeling is based on a suite of programs developed by JVX for the IPR11 and IPR12.

The collated text files for each survey line are taken into a Geosoft database. UTM coordinates for each line/station of the interpolated grid are added. The IP decays are analyzed for spectral content (see below) – the results are added back into the database.

The results are presented as plan maps of the n=1 Mx chargeability and n=1 apparent resistivity and stacked pseudosections. Stacked pseudosections show the Mx chargeability, 2D inverted Mx chargeability, apparent resistivity, 2D inverted resistivity, spectral IP time constant (tau) and spectral IP amplitude (MIP). All are prepared with Geosoft Oasis Montaj. Pseudosections assume an ideal survey line. Plan maps show the IP survey grid, station numbers, the colour grid and line contours. Random gridding with a 16 m grid cell is used.

Impedance Modelling The Cole-Cole impedance model was developed in the 1970s after it became clear that

chargeability is a complex property determined by amplitude (volume percent electronic conductors), grain size and grain size uniformity. In this model, the low frequency electrical impedance Z(ω) of rocks and soils is defined by 4 parameters. They are

r0 : DC resistivity in ohm.m m : true chargeability amplitude in V/V (also called MIP) τ : tau - time constant in seconds c : exponent

The form of the model is Z(ω) = r0 1 – m 1 - (1+(iωτ)c)-1 ohm.m where ω is the angular frequency (2πf).

The true chargeability (m or MIP) is a better measure of the volume percent electronic conductors - primarily pyrrhotite, pyrite and graphite. The time constant is a measure of the square of the average grain size. The exponent is a measure of the uniformity of the grain size. Common or possible ranges are 0 to 1 V/V (m), .01 to 100 seconds (tau) and .1 to .5 (c). In time domain IP surveys, impedance model parameters may be estimated using a best fit between theoretical and measured decays. The simplest approach is to use a set of master decay curves, pre-calculated for selected values of time constant and exponent. For a 2 second current pulse, the master curve set used here is for time constant values of .01, .03, .1, .3, 1, 3, 10, 30 and 100 seconds and exponent values of 0.1, 0.2, 0.3, 0.4 and 0.5. This gives a total of 45 master curves. All decays that give an RMS fit between measured and master decay of less than 5% are judged to be of sufficient quality to yield spectral IP parameters. Under ideal conditions, more than 90 % of the IP decays in any survey are of sufficient amplitude and quality to yield spectral parameters. 80 % is probably average for most surveys. The most common reason for the lack of spectral parameters is very low decay amplitudes – often seen in areas of thick and/or conductive overburden. Instrumentation and/or noise problems can occur over long sections of outcrop or at an abrupt boundary between outcrop and conductive ground.

Impedance Modelling The 2D IP/resistivity inversion results are from DCIP2D, a program library from the UBC Geophysical Inversion Facility for the forward modelling and inversion of DC resistivity and induced polarization data in 2 dimensions. The main steps in any inversion are

1. Model the area under the survey line into a mesh of rectangles. Mesh cells are usually a/2 m wide and a/4 m thick. There must be several cells of increasing size on all 3 sides outside the region where current has been injected.

2. Assign initial chargeability and resistivity values to each mesh cell. The default settings commonly are 0 and 10000 for all mesh cells (half space model).

3. Calculate what would be the measured chargeability and apparent resistivity from the model.

4. Compare the calculated and measured chargeability and apparent resistivity. Use these comparisons to make intelligent changes in the chargeability and resistivity of each mesh cell. Re-calculate what would be the measured chargeability and apparent resistivity from the revised model. Repeat this forward – compare – model change cycle until there is a reasonable fit between the calculated and measured chargeability and apparent resistivity.

The inversion results are not unique – any number of earth models will fit the measured chargeability and apparent resistivity. When properly applied, inversion may correct the IP results for overburden masking, terrain effects and physical attenuation due to depth of burial. When not properly applied, inversion can generate wildly unrealistic IP sections, including false IP anomalies. Inversion results are best viewed in parallel with the measured results. Chargeability highs seen only in the inversion are suspect.

Pseudosections Pseudosections are plotted using standard depth and position conventions. For fixed ‘a’ surveys, the plot point for any measured quantity for the nth potential dipole pair is (n+½)a/2 m forward of and below the current electrode. For combination surveys where the ‘a’ spacing changes from 25 to 50 m, the plot point for any receiver dipole is ‘x’ m forward of and below the current electrode where ‘x’ is half the distance between the current electrode and the centre points of the Rx dipole. Pole-dipole anomaly shapes depend on array orientation. The array sketch shown with each pseudo section shows the correct array orientation.

These plot forms have been found to give a reasonable image of target-top location, width and depth where 1) the anomalously chargeable and/or resistive body is an isolated, tabular body with a dip that is within ± 45° of vertical, 2) where background chargeabilities and resistivities (overburden and host rock) are uniform and 3) where the terrain is relatively flat. They are more difficult to interpret for irregular, nearby or shallow dipping chargeable bodies and where there is any amount of conductive cover or topographic relief. Forward or inverse modelling may be useful in such cases. For Mx, MIP and apparent resistivity, colour contour intervals in the pseudosections are taken from equal area distribution for the whole grid. Colour assignments for the spectral time constant are fixed.

Appendix 3 - IP Anomalies IP anomalies have been picked from pseudosections of Mx chargeability. The spectral chargeability amplitude MIP may be consulted where the anomaly is poorly defined. IP anomalies are identified by the line and station of the centre-top of the IP anomaly. Additions are an identifying letter, the chargeability peak amplitude in mV/V (Mx), the class (C : weak, Moderate or Strong), the dipole number of the anomaly centre-top (n), the spectral IP amplitude (MIP) in mV/V, the time constant range (TC), the n=1 resistivity at or over the centre-top (rho1) and the resistivity expression, if any, of the IP anomaly (resis). The time constant range is shown as S - short (< 0.1 sec), M - moderate or mixed (0.1 to 10 seconds) and L - long (> 10 seconds). A blank entry means the results were incomplete, inconclusive or unavailable. For an IP anomaly to be classified as weak, the peak Mx chargeability is normally in the range of 5 to 10 mV/V. Moderate strength IP anomalies have a peak Mx chargeability of 10 to 20 mV/V. Strong IP anomalies have a peak Mx chargeability of more than 20 mV/V.

Introduction The GSM-19 v7.0 Overhauser instrument is the total field magnetometer / gradiometer of choice in today’s earth science environment -representing a unique blend of physics, data quality, operational efficiency, system design and options that clearly differentiate it from other quantum magnetometers.

With data quality exceeding standard proton precession and comparable to costlier optically pumped cesium units, the GSM-19 is a standard (or emerging standard) in many fields, including:

* Mineral exploration (ground and airborne base station)

* Environmental and engineering * Pipeline mapping * Unexploded Ordenance Detencion

* Archeology * Magnetic observatory measurements * Volcanology and earthquake

prediction

Taking Advantage of the Overhauser Effect

GSM-19 v7.0Overhauser

Magnetometer / Gradiometer / VLF

Overhauser effect magnetometers are essentially proton precession devices except that they produce an order-of magnitude greater sensitivity. These "supercharged" quantum magnetometers also deliver high absolute accuracy, rapid cycling (up to 5 readings / second), and exceptionally low power consumption. The Overhauser effect occurs when a special liquid (with unpaired electrons) is combined with hydrogen atoms and then exposed to secondary polarization from a radio frequency (RF) magnetic field. The unpaired electrons transfer their stronger polarization to hydrogen atoms, thereby generating a strong precession signal-- that is ideal for very high-sensitivity total field measurement.

In comparison with proton precession methods, RF signal generation also keeps power consumption to an absolute minimum and reduces noise (i.e. generating RF frequencies are well out of the bandwidth of the precession signal).

In addition, polarization and signal measurement can occur simultaneously - which enables faster, sequential measurements. This, in turn, facilitates advanced statistical averaging over the sampling period and/or increased cycling rates (i.e. sampling speeds).

The unique Overhauser unit blends physics, data quality, operational efficiency, system design and options into an instrumentation package that ... exceeds proton precession and matches costlier optically pumped cesium capabilities. And the latest v7.0 technology up-grades provide even more value, including: - Data export in standard XYZ (i.e. line-oriented) format for easy use in standard commercial software programs - Programmable export format for full control over output

- GPS elevation values provide input for geophysical modeling

- <1.5m standard GPS for high- resolution surveying

- <1.0 OmniStar GPS

- <0.7m for Newly introduced CDGPS

- Multi-sensor capability for advanced surveys to resolve target geometry

- Picket marketing / annotation for capturing related surveying information on the go.

And all of these technologies come complete with the most attractive prices and warranty in the business!

MAGNETOMETERS

Maximizing Your Data Quality with the GSM-19

Data quality is a function of five key parameters that have been taken into consideration carefully in the design of the GSM-19. These include sensitivity, resolution, absolute accuracy, sampling rates and gradient tolerance.

Sensitivity is a measure of the signal-to noise ratio of the measuring device and reflects both the underlying physics and electronic design. The physics of the Overhauser effect improves sensitivity by an order of magnitude over conventional proton precession devices. Electronic enhancements, such as high-precision precession frequency counters enhance sensitivity by 25% over previous versions.

The result is high quality data with sensitivities of 0.022 nT / vHz. This sensitivity is alsothe same order-of magnitude as costieroptically pumped cesium systems.

Resolution is a measure of the smallest number that can be displayed on the instrument (or transmitted via the download process). The GSM-19 has unmatched resolution (0.01mT)

This level of resolution translates into well-defined, characteristic anomalies; improved visual display; and enhanced numerical data for processing and modeling.

Absolute accuracy reflects the closeness to the "real value" of the magnetic field -- represented by repeatability of readings either at stations or between different sensors. With an absolute accuracy of +/- 0.1 nT, the GSM-19 delivers repeatable station-to-station results that are reflected in high quality total field results.

Similarly, the system is ideal for gradient installations (readings between different sensors do not differ by more than +/- 0.1 nT) -- maintaining the same high standard

of repeatability.

The GSM-19 gradiometer data are consistently low in noise and representative of the geologic environment under investigation.

Sampling rates are defined as the fastest speed at which the system can acquire data. This is a particularly important parameter because high sampling rates ensure accurate spatial resolution of anomalies and increase survey efficiency.

The GSM-19 Overhauser system is configured for two "measurement modes" or maximum sampling rates --"Standard" (3 seconds / reading), and"Walking" (0.2 seconds / reading)These sampling rates make the GSM-19 a truly versatile system forall ground applications (including vehicle-borne applications).

Gradient tolerance represents the ability to obtain reliable measurements in the presence of extreme magnetic field variations. GSM-19 gradient tolerance is maintained through internal signal counting algorithms, sensor design and Overhauser physics. For example, the Overhauser effect produces high amplitude, long-duration signals that facilitate measurement in high gradients.

The system's tolerance (10,000 nT / meter) makes it ideal for many challenging environments -- such as highly magnetic rocks in mineral exploration applications, or near cultural objects in environmental, UXO or archeological applications.

unaffected by diurnal variation. Absolute accuracy is also shown to be

very high (0.2 nT/meter).

Much like an airborne acquisition system, the GSM19 “Walking” magnetometer option delivers very

highly-sampled, high sensitivity results that enable very accurate target location and / or earth science

decision-making.

Increasing Your Operational Efficiency Many organizations have standardized their magnetic geophysical acquisition on the GSM-19 based on high performance and operator preference. This preference reflects performance enhancements such as memory capacity; portability characteristics; GPS and navigation; and dumping and processing. Memory capacity controls the efficient daily acquisition of data, acquisition of positioning results from GPS, and the ability to acquire high resolution results (particularly in GSM-19’s "Walking" mode). V7.0 upgrades have established the GSM19 as the commercial standard for memory with over 1,465,623 readings (based on a basic configuration of 32Mbytes of memory and a survey with time, coordinate, and field values).

Portability characteristics (ruggedness, light weight and power consumption) are essential for operator productivity in both normal and extreme field conditions.

GSM-19 Overhauser magnetometer is established globally as a robust scientific instrument capable of withstanding temperature, humidity and terrain extremes. It also has the reputation as the lightest and lowest power system available -- reflecting Overhauser effect and RF polarization advantages.

In comparison with proton precession and optically pumped cesium systems, the GSM-19 system is the choice of operators as an easy-to-use and robust system.

GPS and navigation options are increasingly critical considerations for earth science professionals.

GPS technologies are revolutionizing data acquisition -- enhancing productivity, increasing spatial resolution, and providing a new level of data quality for informed decision-making.

The GSM-19 is now available with real-time GPS and DGPS options in different survey resolutions. For more details, see the GPS and DGPS section.

The GSM-19 can also be used in a GPS Navigation option with real-time coordinate transformation to UTM, local X-Y coordinate rotations, automatic end of line flag, guidance to the next line, and survey "lane" guidance with cross-track display and audio indicator.

Other enhancements include way point pre-programming of up to 1000 points. Professionals can now define a complete survey before leaving for the field on their PC and download points to the magnetometer via RS-232 connection.

The operator then simply performs the survey using the way points as their survey guide. This capability decreases survey errors, improves efficiency, and ensures more rapid survey completion.

Dumping and processing effectiveness is also a critical consideration today. Historically, up to 60% of an operator's "free" time can be spent on low-return tasks, such as data dumping.

Data dumping times are now significantly reduced through GEM’s implementation of high-speed, digital data links (up to 115 kBaud).

MAGNETOMETERS

This functionality is faciliated through a new RISC processor as well as the new GSM-19 data acquisition / display software. This software serves as a bi-directional RS-232 terminal. It also has integrated processing functionality to streamline key processing steps, including diurnal data reduction. This software is provided free to all GSM19 customers and regular updates are available.

Navigation and Lane Guidance

The figure above shows the Automatic Grid (UTM, Local Grid, and Rotated Grid). With the Rotated Grid, you can apply an arbitrary origin of your own definition. Then, the coordinates are always in reference to axes parallel to the grid. In short, your grid determines the map, and not the NS direction.

The Local Grid is a scaled down, local version of the UTM system, and is based on your own defined origin. It allows you to use smaller numbers or ones that are most relevant to your

Adding Value through Options

When evaluating the GSM-19 as a solution for your geophysical application, we recommend considering the complete range of options described below. These options can be added at time of original purchase or later to expand capabilities as your needs change or grow.

Our approach with options is to provide you with an expandable set of building blocks:

* Gradiometer * *

Walking- Fast Magnetometer / Gradiometer VLF (3 channel)

* GPS (built-in and external)

GSM-19G Gradiometer Option

The GSM-19 gradiometer is a versatile, entry level system that can be upgraded to a full-featured "Walking" unit (model GSM-19WG) in future.

The GSM-19G configuration comprises two sensors and a "Standard" console that reads data to a maximum of 1 reading every three seconds.

An important GSM-19 design feature is that its gradiometer sensors measure the two magnetic fields concurrently to avoid any temporal variations that could distort gradiometer readings. Other features, such as single-button data recording, are included for operator ease-of-use.

GSM-19W / WG "Walking" Magnetometer / Gradiometer Option

The GSM-19 was the first magnetometer to incorporate the innovative "Walking" option which enables the acquisition of nearly continuous data on survey lines. Since its introduction, the GSM-19W / GSM-19WG have become one of the most popular magnetic instruments in the world.

Similar to an airborne survey in principle, the system records data at discrete time intervals (up to 5 readings per second) as the instrument is carried along the line.

At each survey picket (fiducial), the operator touches a designated key. The system automatically assigns a picket coordinate to the reading and linearly interpolates the coordinates of all intervening readings (following survey completion during post-processing).

A main benefit is that the high sample density improves definition of geologic structures and other targets (UXO, archeological relics, drums, etc.).

It also increases survey efficiency because the operator can record data almost continuously. Another productivity feature is the instantaneous recording of data at pickets. This is a basic difference between the “Walking” version and the GSM-19 / GSM-19G (the “Standard” mode version which requires 3 seconds to obtain a reading each time the measurement key is pressed).

GSM-19 "Hands-Free" Backpack Option The "Walking" Magnetometer and Gradiometer can be configured with an optional backpack-supported sensor. The backpack is uniquely constructed -permitting measurement of total field or gradient with both hands free. This option provides greater versatility and flexibility, which is particularly valuable for high-productivity surveys orin rough terrain.

MAGNETOMETERS

GSM-19GV "VLF" Option

With its omnidirectional VLF option, up to 3 stations of VLF data can be acquired without orienting. Moreover, the operator is able to record both magnetic and VLF data with a single stroke on the keypad.

MAGNETOMETERS More About the Overhauser System

In a standard Proton magnetometer, current is passed through a coil wound around a sensor containing a hydrogenrich fluid. The auxiliary field created by the coil (>100 Gauss) polarizes the protons in the liquid to a higher thermal equilibrium.

When the current, and hence the field, is terminated, polarized protons precess in the Earth's field and decay exponentially until they return to steady state. This process generates precession signals that can be measured as described below.

Overhauser magnetometers use a more efficient method that combines electronproton coupling and an electron-rich liquid (containing unbound electrons in a solvent containing a free radical). An RF magnetic field -- that corresponds to a specific energy level transition -- stimulates the unbound electrons.

Instead of releasing this energy as emitted radiation, the unbound electrons transfer it to the protons in the solvent. The resulting polarization is much larger, leading to stronger precession signals.

Both Overhauser and proton precession, measure the scalar value of the magnetic field based on the proportionality of precession frequency and magnetic flux density (which is linear and known to a high degree of accuracy). Measurement quality is also calculated using signal amplitude and its decay characteristics. Values are averaged over the sampling period and recorded.

With minor modifications (i.e. addition of a small auxiliary magnetic flux density while polarizing), it can also be adapted for high sensitivity readings in low magnetic fields. (ex. for equatorial work)

GPS - Positioning You for Effective Decision Making

The use of Global Positioning Satellite (GPS) technology is increasing in earth science disciplines due to the ability to make better decisions in locating and following up on anomalies, and in improving survey cost effectiveness and time management.

Examples of applications include: Surveying in remote locations with no grid

* High resolution exploration mapping * High productivity ferrous ordnance (UXO) detection * Ground portable magnetic and gradient surveying for environmental

and engineering applications * Base station monitoring for observing diurnal magnetic activity and

disturbances with integrated GPS time

The GSM-19 addresses customer requests for GPS and high-resolution Differential GPS (DGPS) through both the industry’s only built-in GPS (as well as external GPS).

Built-in GPS offers many advantages such as minimizing weight and removing bulky components that can be damaged through normal surveying. The following table summarizes GPS options.

Key System Components

Key components that differentiate the GSM-19 from other systems on the market include the sensor and data acquisition console. Specifications for components are provided on the right side of this page.

Sensor Technology

Overhauser sensors represent a proprietary innovation that combines advances in electronics design and quantum magnetometer chemistry.

Electronically, the detection assembly includes dual pick-up coils connected in series opposition to suppress far-source electrical interference, such as atmospheric noise. Chemically, the sensor head houses a proprietary hydrogen-rich liquid solvent with free electrons (free radicals) added to increase the signal intensity under RF polarization.

From a physical perspective, the sensor is a small size, light-weight assembly that houses the Overhauser detection system and fluid. A rugged plastic housing protects the internal components during operation and transport.

All sensor components are designed from carefully screened non-magnetic materials to assist in maximization of signal-to-noise. Heading errors are also minimized by ensuring that there are no magnetic inclusions or other defects that could result in variable readings for different orientations of the sensor.

Optional omni-directional sensors are Performance available for operating in regions where the magnetic field is near-horizontal (i.e. Sensitivity: 0.022 nT / vHz@1Hzequatorial regions).
