A. SUMMARY AND RECOMMENDATIONSA diamond drill program is recommended to test an interpreted fold
ructures and area of anomalously low magnetic susceptibility in the quartz magnetite ironstone unit located at 4+25W from L2N to 2S.
B. INTRODUCTION
The Lundmark Lake property of Esso Minerals Canada consists of 15 contiguous unpatented mining claims held by Esso Resources Canada Limited under option from Mr. Ernest Bazinet. These claims are numbered Pa 1006276 through Pa 1006290. A program of linecutting and geophysical surveying was conducted between March and June of 1988.
The exploration program was conducted in order to evaluate the potential for gold mineralization in silicate-facies ironstone in the style of the Opapimiskan Lake deposit located 20 kilometres to the southeast. An ironstone has been interpreted on the property from airborne geophysical surveys published by the Ontario Geological Survey.
C. LOCATION AND ACCESS
The 15 claims of the Lundmark Lake Property are shown on Figure 4. A complete list of claims is found in Appendix I. The property is located south and west of Lundmark Lake, some 4 or 5 kilometers east of the north-eastern-most end of North Caribou Lake. Access to the lake, and hence, the adjourning claims is possible for light, fixed-wing, float-equipped aircraft chartered from Pickle Lake.
D. TOPOGRAPHY AND VEGETATION
The area is relatively flat and low-lying in most parts. These areas are hummocky, mossy and have a moderate cover of tag alder and black spruce. Other areas consist of boulder fields and ridges that have thin overburden, and correspondingly less vegetation cover. The shores of the lake are either bouldery with thick vegetation, or boggy, wet and mossy.
E. PREVIOUS EXPLORATION
Reconnaissance mapping was carried out in 1985 by the Ontario Geological Survey (O.G.S. Map P2965). Very few outcrops were located in this program. An airborne EM and magnetometer survey was flown over the area in 1985 for the O.G.S. Mineral exploration has been carried out east and north of the claim group, concentrating upon aeromagnetic and airborne electromagnetic anomalies interpreted to coincide with ironstone units. A brief summary of exploration work done in the Lundmark Lake region is summarized in Appendix IV.
F. REGIONAL GEOLOGY
The North Caribou Lake meta sediment-metavolcanic terrain forms part of the Sachigo Subprovince, which consists of several relatively small accurate and irregularly shaped metavolcanics-metasedimentary belts surrounded mainly by younger granitoid rocks.
The northwestern part of the North Caribou Lake belt consists for the most part of a thick clastic metasedimentary sequence (Eyapamikawa Lake Metasediments) flanked to the north and south by mafic metavolcanics (North River and South River Metavolcanics, respectively). The North River and South River Metavolcanics, and the intervening Eyapamikama Lake Metasediments extend continuously past Akow Lake to the Opapimiskam Lake area. The overall width of

Both clastic and chemical metasediments occur. The oxide-bearing ironstones and iron-rich pelites or silicate facies ironstone host gold deposits at Opapimiskan Lake, The gold occurrence at Opapimiskan Lake is stratabound and uniformly distributed throughout a large volume of rock.
The majority of the property is comprised of massive or pillowed mafic metavolcanics of the South River Metavolcanics sequence. In the south-western most corner of the property, metamorphosed and foliated portions of the North Caribou Lake Batholith comprised of granites and diorites.
G. RESULTS OF THE GEOPHYSICAL SURVEY
i. IntroductionThe claims which comprise the property were recently optioned from Mr. E.
Bazinet. Linecutting was conducted from March 15th to March 25th, 1988.
As the regional trend for stratigraphy in the area is roughlynorthwest-southeast, the baseline for the grid was cut to an orientation of 33?" to ensure geophysical surveys were conducted perpendicular to strike.
A summary of the personnel, contractors, dates worked and qualifications of the author and supervisor of the work is given in Appendix II.
A ground magnetometer and VLF-EM survey was conducted on the grid from April 8-12, 1988 by Northwest Geophysics using the OMNI-PLUS system described in Appendix III. The results of these surveys are presented in Maps l, 2, and 3 at a scale of 1:5000.
ii. Interpretation of the Results
a. Magnetite- and Pyrrhotite-bearing IronstonesThe magnetite- and pyrrhotite-bearing ironstones are characterized by
moderately high but variable magnetic susceptibility accompanied by a VLF-EM response in areas of continuous massive sulfides. The massive iron sulfides are typically lensoidal and may not continue along strike.
The dominant ironstone unit(s) are interpreted to subcrop from: L 7N 2+50W to 6S 3+OOW
L IN 4+25W to 5S 3+75W
L 12N 2+50E to 7N 1+50EThe units appear reasonably linear magnetic features and the only possible fold structure occurs between 2N and 2S at 4+25W. It is this folded ironstone which represents the best potential area for gold mineralization and is recommended for drill testing.

APPENDIX III
Survey Specifications and Data Reduction Techniques
A. IntroductionThe survey was carried out with an EDA "OMNI PLUS" VLF-
Magnetometer system. More information on the OMNI PLUS system is available in the copy of the OMNI PLUS brochure contained in this Appendix.
B. Magnetometer SurveyThe "OMNI PLUS" magnetic field strength measurement utilizes
the precession of spinning protons (hydrogen nuclei) in a sample of hydro-carbon fluid. The protons behave as small magnetic dipoles. These are temporarily polarized by a uniform magnetic field generated by a current in a coil of wire. When the current is removed, the spin of the protons causes them to precess about the direction of the earth's magnetic field. The precessing protons then generate a signal in the coil, whose frequency is proportiona.1 to the total magnetic field intensity. The processing sensitivity of the OMNI PLUS is . 02 Gammas.
Measurements were taken with the OMNI PLUS at 12.5 metre intervals along survey lines spaced 100 metres apart. To correct for time variations of the earth's magnetic field (diurnal), a second OMNI system was used as a base station monitor/recorder with readings every thirty seconds or less. Changes in the base station readings were automatically removed at the end of each survey day from the measurements obtained along the survey lines.
A datum/zero level of 59,000 nT was subtracted from the corrected magnetic measurements for presentation purposes. The final, corrected readings are plotted on Figure 2 and a contoured plan of the data at a contour interval of lOOOnT is presented in Figure 3 at a scale of 1:5000.
C. VLF-EM SurveyThe VLF (Very Low Frequency) EM method employs an artificial
source of EM waves - a VLF antenna, several hundred feet high, which acts essentially as a vertically grounded wire. A worldwide- network of high-power VLF stations established for marine and air navigation, act as the sources for the VLF-EM exploration method. At present, suitable transmitters for EM prospecting in North America are located at Cutler, Maine; Annapolis, Md. and Seattle, Washington. The transmitted frequencies (in the 20 KHz band) are very low frequency (VLF) only by comparison to broadcasting standards, but are in fact very high relative to any other geophysical EM system.
The VLF antenna current is vertical. The main magnetic field component of the primary (transmitted) signal is horizontal and theoretically tangent to circles about the antenna mast. Hence, a transmitting station should be chosen so that its direction is almost parallel to the geological strike in the survey area so as to produce a magnetic field perpendicular to the strike. If a conductor is located in the survey area, eddy currents are established producing a secondary field in the vicinity of the conductor. The OMNI PLUS equipment measures the vertical components of this secondary field.
The fact that the source is at infinity means the primary field is essentially uniform over the survey area and hence all conductors are energized uniformly. This enables the detection of
l l l l l l l l l l l l l l l l l l l
a broad variety of conductors, ranging from good conductors -
Caphite, massive sulphides, to poor conductors - muskeg, clay ges, shear zones, contacts. At times this may be a disadvantage,
however, since it may emphasize large-scale, relatively poor conductors at the expense of smaller concentrated bodies. In many environments, the anomalies of interest can be masked by the large amount of geological noise. The penetration of the system is limited by its high frequency in the presence of conductive overburden. However, if the subsurface is resistive, for example, little overburden, the penetration can be quite deep due to the transmitter being so far removed.
The VLF-EM method is also affected by topographic effects, spurious anomalies being picked up on top of conductive hills because the resultant field tends to follow the slope. The distinction between anomaly conductivity and depth is also often difficult. Another major drawback is that it is not always possible to use a transmitting station which gives a primary horizontal field striking at right angles to the geologic strikes in the survey area. In this case, two VLF transmitters, at approximately right angles to each other, should be used to provide better coverage.
The OMNI PLUS system utilizes three orthogonal sensor coils rather than two sensor coils used in conventional systems. The system requires no orientation, by the operator, of the sensor head toward the transmitting station. Instead, the OMNI PLUS compensates automatically for the direction of travel along the survey grid lines as well as for the angle of the sensors from the vertical plane through the use of tiltmeters. The OMNI PLUS then calculates and records in memory the in-phase and vertical quadrature of the VLF-EM field. The system calculates each of these two parameters from the in-phase and quadrature measurements at all three sensor heads.
Readings were taken at 12.5 metre intervals along survey lines spread 100 metres apart. The Cutler, Maine station was used for this survey.
The in-phase and quadrature responses are posted and platted in profile plan form at a horizontal scale of 1:5000 and a vertical scale of l cm=50% on Figures 1.

BenefitsCombined VLF 7 Magneto meter/ Gradiometer SystemThe OMNI PLUS incorporates the capabilities of the OMN! IV "Tie- Line" Magnetometer and Gradiometer System with the ability t9 measure the VLF magnetic and electric fields.Only one OMNI PLUS is needed to' record all of the following geophysical parameters:
1. The total magnetic field2. The simultaneous gradient of
the total magnetic field3. The VLF magnetic field,
including:- the total dip- the total field strength of the VLF magnetic field
- the vertical quadrature, or alternately, the horizontal
. amplitude A. The VLF electric field,
including:- the phase angle-apparent resistivity
As an example, at each location the OMNI PLUS can cs/cufate and
record in a matter of seconds, three VLF magnetic field and two VLF electric field parameters from two different transmitters, a magnetic total field reading and a simultaneous magnetic gradient reading.
No Orientation RequiredThe OMNI PLUS requires no orientation, by the operator, of the sensor head toward the transmitter station. This simplifies field procedures as well BS saving considerable survey time. When two VLF transmitters are measured, the benefits of this time-saving feature are auto matically doubled. There is no requirement for the operator to orient himself and the sensor head toward the first selected transmitting station and then re orient towards the second trans mitting station.Consistent high quality data is achieved in the OMNI PLUS due to the utilization of three ortho gonal sensor coils rather than two sensor coils used in conventional systems. The quality of data is not then dependent on the operator's ability to correctly orient the sensor head for optimum coupling with the transmitting station.The OMN! PLUS compensates automatically for the direction of travel along the grid lines as well as for the angle of the sensors from the vertical plane through the use of tiltmeters.
Three VLF Magnetic Parameters RecordedThe OMNI PLUS calculates and records in memory the:-total dip- tots! field strength- vertical quadrature The operator has the option to substitute the horizontal amplitude for the vertical
lKadrature. The OMNI PLUS
culates each of these rameters from the in-phase
and quadrature measurements f all three components.
Automatic calculation of
taser Filter e OMNI PLUS automatically
calculates the Fraser Filter, from
(e dip angle data, regardless of e interval between the stations Dng the grid lines. The operator
(longer has to manually per- m this mathematical calcula- n thereby reducing the pos
sibility of human error. The Baser Filter algorithm follows es-
blished conventions.The operator can choose to out- out e ither the total dip or the Baser filtered data, or both.
KIculation of Ellipticity e OMNI PLUS calculates the true
ellipticity of the VLF magnetic
( Id from the measurement of e in-phase and quadrature of three components. The
ellipticity provides more
Icerpretative information about e anomaly than the dip angle
and is less influenced by over- rden shielding.I
Automatic Correction of irnary Field Variations
Ie OMNI PLUS can be used as a base station to monitor primary fcld changes from up to three WF transmitters as well as Sernately measuring the variations in the magnitude of
earth's magnetic field. Only _e OMNI PLUS is needed to perform both functions.
X i OMNI PLUS base station can n automatically correct, by :ar interpolation, the field
units for these drift variations in
t primary VLF and total gnetic fields.
Measurement of VLF Electric FieldThe OMNI PLUS calculates and records the apparent resistivity and phase angle from the measurement of the VLF electric field. This VLF electric field measurement can be accomplish ed by using capacitively or resistively coupled electrodes at spacings of 5,10 or 20 meters.
Other BenefitsAutomatic TuningThe OMNI PLUS automatically tunes up to three VLF trans mitters within a frequency range of 15 to 30 kHz, once the operator has programmed in the specific frequencies.
Base Station SynchronizationThe OMNI PLUS has a unique "count-down" feature which can be activated in the field unit upon synchronization with the base station. The field unit then displays and decrements the re maining time, in seconds, until the base station is scheduled to ' take a measurement. The operator can obtain a field reading at exactly the same time as the base station. The sim ultaneous field and base station measurements significantly im prove the automatic correction accuracy.
Automatic "Tie-Line" CorrectionThe OMNI PLUS can automatically correct by itself the VLF field data for atmospheric variations and changes in-the primary field originating from the VLF transmitter. By tieing-back into one or several tiepoints on the grid, the OMNI PLUS will
automatically calculate and apply the drift measured to the field data previously recorded in memory. More information on this unique "tie-line" method can be obtained from page 3 of the OMNI IV brochure.
Notation of Natural and Cultural FeaturesThe OMNI PLUS can record natural and cultural features unique to each grid location. This capability eliminates the need for a field notebook and provides additional information that can assist in interpreting recorded data.
Analogue OutputSince VLF as well as magnetic data is often easier to interpret as a profile plot, data collected by the OMNI PLUS can be represented in analogue format at a vertical scale best suited for data presentation. The operator can selectively output in analogue and/or digital format, up to 10 of the following parameters:- total d ip- Fraser filtered data- ellipticity- VLF total field strength- vertical quadrature- horizontal amplitude- apparent resistivity-phase angle- magnetic total field strength- magnetic vertical gradient
Computer interfaceThe OMNI PLUS can transfer un- corrected, corrected or filtered data to most computers with a RS252C port. In some cases, a DCA-100 Data communications Adaptor may be required, computers with collection packages including either "X-ON,X-OFF"or"ENQMCK" communications protocol formats are also compatible.
