INTRODUCTION.

Between April 1 st and 7th, 2002, Peter E. Walcott fc Associates Limited undertook limited induced polarization surveying over part of the Armstrong property, located some 15 kilometres west northwest of the settlement of Armstrong, Ontario, for Valeric Gold Resources Ltd. of Vancouver, British Columbia.

The survey was an add-on to a three line survey carried out by Geoserve Canada Inc. of Timmins, Ontario in January 2002, which was curtailed due to the inability to inject current into the frozen ground.

Two traverses of some 1500 metres in length were carried out on the previously established Line 5000N, and the newly cut Line 4875N, established by the I.P. crew, with the bearing of the lines at N 670 E.

Measurements - first to sixth separation - of apparent chargeability - the I.P. response parameter - and resistivity were made along the aforementioned lines using the pole- dipole technique with a 50 metre dipole.

The data are presented in contour form on individual pseudo sections bound in this report.

The progress of the survey was severely hampered by the frozen ground conditions and the overlying snow cover - in cases taking over an hour to attain injection of the required minimum of 200 milliamps into the ground.

GEOLQGY.

Basically the property is underlain by foliated Archean tonalite through granodiorite rocks, intruded in places by Nippissing diabase. The Black Sturgeon fault, which with related rift-graben structures coincide and were the likely conduits for the large mafic to ultramafic intrusions to the south, which demonstrate PGE element associations - the basis for the Noril'sk model -, is projected to run through the claim block.

For further information the reader is referred to reports held by Valeric Gold Resources Ltd.

PREVIQUS WORK.

The writer is unfamiliar with previous work in the property area except for some lakebottom, soil and rock chip sampling, and the previously mentioned I.P. survey byGeoserve.For further reference the reader is referred to the aforementioned reports of the previoussection.

PURPOSE.

The purpose of the survey was to ascertain the response, if any, of the PGE mineralization noted in outcrop at the base of the steep cliff on the eastern edge of the narrow linear north northwest trending lake on the western extremities of the original grid, and to use this response to map out areas of mineralization.

SURVEY SPECIFICATIONS.

The induced polarization (IP.) survey was conducted using a pulse type system, the principal components of which are manufactured by Iris Instruments of Orleans, France.

The system consists basically of three units, a receiver (Iris), transmitter and a motor generator (Iris). The transmitter, which provides a maximum of 4.0 kw d.c. to the ground, obtains its power from a 4 kw 400 c. p. s. three phase alternator driven by a gasoline engine. The cycling rate of the transmitter is 2 seconds "current-on" and 2 seconds "current-off with the pulses reversing continuously in polarity. The data recorded in the field consists of careful measurements of the current (I) in amperes flowing through the current electrodes Ci and Cj, the primary voltages (V) appearing between any two potential electrodes, PI through P?, during the "current-on" part of the cycle, and the apparent chargeability, (Ma) presented as a direct readout in millivolts per volt using a 200 millisecond delay and a 1000 millisecond sample window by the receiver, a digital receiver controlled by a micro-processor - the sample window is actually the total of ten individual windows of 100 millisecond widths.

The apparent resistivity ( fa) in ohm metres is proportional to the ratio of the primary voltage and the measured current, the proportionality factor depending on the geometry of the array used. The chargeability and resistivity are called apparent as they are values which that portion of the earth sampled would have if it were homogeneous. As the earth sampled is usually inhomogeneous the calculated apparent chargeability and resistivity are functions of the actual chargeability and resistivity of the rocks.

The survey was carried out using the "pole-dipole" method of surveying. In this method the current electrode, Ci, and the potential electrodes, PI through P7, are moved in unison along the survey lines at a spacing of "a" (the dipole) apart, while the second current electrode, C2, is kept constant at "infinity". The distance, "na" between Ci and the nearest potential electrode generally controls the depth to be explored by the particular separation, "n", traverse.

On this survey a 50 metre dipole was employed and first to sixth separation readings were obtained.

SURVEY SPECIFICATIONS cont'd

Considerable problems were encountered in trying to place the "infinity"- Ci - to ensure the passage of sufficient current for reliable readings, and several locations had to be tried before a suitable one with an appropriate contact resistance was found. Subsequently, as mentioned previously, considerable time was spent in reducing the contact resistance of the six stainless steel stakes used for the current electrode Ci, particularly on the esker at the western extremity of the grid lines, where moving them six or more times with the application of some 5 gallons of salt water was not uncommon to ensure the injection of the minimum 200 milliamps - not to mention the fact that the stakes needed to be extracted with the use of vice-grips after each insertion.

In all some 2.7 kilometres of surveying were completed on two lines before a decision was made to delay further work until summer as it was not possible to scale the cliff at any other location - Figure 2.

DISCUSSION OF RESULTS

The writer will not dwell extensively on the results of the survey as Valeric Gold has decided to drop its option on the property.

The resistivity and chargeability results compare favourably with those obtained by Geoserve on the higher ground to the east above the cliff on Line 5000N where contacts were easier to obtain, but the chargeabilities differed somewhat west of 4300 E.

A broad zone of higher chargeability can be seen between 4175 and 4700E on the pseudo section with an increased near surface response between 4250 and 4600E.

A pant-leg shaped resistivity low can be observed around 4200E partially occasioned by the shear hosting the mineralization, but also due to the topography and the lake to the west.

A similar resistivity low can also be seen on Line 4875N - the only other place to run a traverse up the cliff. The shallow chargeability response is also discernible around 4400E, but the western edge of the broad zone shifts 50 metres westward.

The two zones of higher chargeability between 3800 and 41 GOE on Line 5000N appear compressed into one between 3800 and 3875E on Line 4875N associated with lower resistivities.

No distinctive signature was obtained over the showings but in the writer's opinion a 25 metre dipole would have been better suited for this determination.

SUMMARY. CONCLUSIONS AND RECOMMENDATIONS.

Between April 1 st and 7th, 2002, Peter E. Walcott & Associates Limited undertook limited induced polarization surveying (IP.) over part of a property located in northwestern Ontario, for Valeric Gold Resources Ltd.

The survey was carried out on two short traverses up a cliff where access was limited in an effort to determine the I.P. response over the PGE and associated sulphide mineralization observed in showings along the base of the same cliff.

No distinctive signature was noted over the area of interest with the large dipole used - 50 metre -, but the mineralization appeared to be part of a large moderate response.

A better defined chargeability high was noted further to the west on Line 4875N accompanied by a decrease in resistivity.

This feature and the mineralized horizon should be geologically ground truthed and sampled in the summer months before further commitment to additional I.P. surveying.
