SUMMARY

i

Induced polarization and resistivity surveys were carried out during September and October, 1988 over a portion of the CK claims located on Raft River, 53 km north of Clearwater. British Columbia. The purpose of the work was to locate sulphide mineralization containing lead, zinc and silver.

I

I The property is easily accessible by 4-wheel drive vehicle by a series of logging roads from Clearwater. The terrain consists of moderate to steep slopes covered with moderately-populated fir, spruce, and cedar trees with moderate underbrush.

Most of the property is underlain by rocks of the Shuswap Metamorphic complex. This complex consists of a belt of amphibolite facies metasediments and orthogneiss which extends North to Hobson Lake and continues in a south-easterly direction for at least 200 kilometers. These are highly deformed pelitic and carbonate rocks which are often intruded by pegmatite and granitic gneiss, marbles and quartzites. Mineralization on the property occurs as stratiform lead-zinc occurrences with zinc content exceeding lead by a 5:l ratio.

The IP and resistivity surveys were carried out using a Huntec receiver operating in the time-domain mode with the dipole- dipole array at 5 to 7 separations. The dipole length and reading interval were 60-m. Nine lines were done.

CONCLUSIONS

I

1 . The resistivity survey has revealed an extensive anomalous low zone, labelled A, which correlates with a moderate I. P. anomalous zone. This anomalous feature stretches across at least six of the I.P. lines, from line G2 to at least G8, for a minimum length of 2500 metres. The causative source is possibly a lithologic change, with associated sulphides of economic interest, between biotite gneisses on the east side, and marbles/intrusives on the west side.

2. Three other resistivity anomalies occur on line G2, and are labelled B to D. These likely represent geological structures such as fault or fracture zones, or geologic strata.

3. Other IP (chargeability) anomalies occur from near surface to depth on several of the lines, and could reflect sulphide mineralization.


iii

RECOMMENDATIONS

1 . Anomalies A to D should be drilled to qualify the anomalies with true geological data. It should be remembered that determining true geological dips from I.P. and resistivity data is difficult, and that if one drill direction produces poor results, the opposite direction is recommended which may allow better interpretation of other anomalies. Pending the results, the following recommendations should be followed through with,

2. Some control over anomalies B to D could be obtained by extending some of the I.P./resistivity survey lines further northwesterly. Also, extending line G1 could further determine the extent of anomaly A northeasterly.

3 . Because of the large distance between the survey lines, it may be difficult to determine the continuity of any new anomalies from the surveys of recommendation (2) above. For this reason, detail lines may have to be run between the present lines. This detailing attempt may be preferred between lines G8 and G6, as well.

KAMLOOPS MINING DIVISION I BRITISH COLUMBIA

INTRODUCTION AND GENERAL REMARKS

This report discusses the instrumentation, theory, field procedure and results of induced polarization (IP) and resistivity surveys carried out over a portion of the CK claims, located over the Raft River in central British Columbia.

The field work was completed from September 22nd to October 17th, 1988 under the supervision of David G. Mark and under the alternate field supervision of Tracy Campbell, geophysicist, and Marc Beaupre, senior geophysical technician who also formed part of the field crew. A geophysical technician as well as two helpers completed the crew of four.

The main purpose of the resistivity survey was to map the con- tacts between the metasediments and volcanics. The purpose of the IP survey was to locate sulphides associated with the contact .

1 PHYSIOGRAPHY

The following is quoted from J.L. Oliver's 1987 drilling and geological report on the CK property.

"Elevation on the subject claims ranges between 850 and 1,700

metres. The topography is characterized by high interior plateaus, moderate rolling hills, which are steeply incised through three major drainage systems, Stratton Creek, Richie Creek and the Raft River. Valley walls are steep but accessible. I "An extensive forest fire in the late 1 9 4 0 ' s has produced thick second growth pine and spruce over much of the claim block. Thick stands of cedar are found in the lower elevations and within creek drainages. Undergrowth is typically extensive, and comprised dominantly of alder, aspen and snow brush. Annual precipitation is moderate, yearly snowfall averages 1.5 to 2.5 metres, with much of the claim block snowfree from late May to early October. The field season corresponds to this interval. Temperature ranges from -40 to +35 degrees Celsius may be ex- pected. Water for diamond drilling is available from numerous seasonal drainages but many of these are too small for drilling purposes by late August.

"Outcrop density is generally poor, less than 5 percent, with reliable exposures typically available only in the larger creek drainages. Most of the property is covered with an extensive coarse boulder till, which on average increases in thickness, often greater than 10 metres, in the lower valleys."

HISTORY OF PREVIOUS WORK

The history of the property is taken from Oliver's 1987 geological report:

"The property has been known and worked intermittently for the past 15 years. The discovery of high grade mineralized float near Kowalski Creek by Andy Horne in 1973 , lead to the staking of a large claim block which covered many of the occurrences subsequently found. Horne and second party, W.M. Bath Invest- ments optioned the property to Rio Tinto in that same year (Murrell, 1 9 8 0 ) .

"From 1974 to 1975 Rio Tinto conducted airborne EM/Mag surveys, directed an extensive program of soil geochemical surveys in the Main Boulder, New Showing area, and conducted a four hole diamond drill program on the Main Boulder occurrence. Ground pros- pecting and geological mapping resulted in the discovery of the East Side occurrence, on which three holes were drilled. Thin stratiform mineralization was intersected in two of the three holes, but these results were viewed as an insufficient basis to continue exploration (Murrell, 1 9 8 0 ) .

"The property was then optioned to Sicintine Mines, who operated a limited exploration program during 1976 . Their attempts to backhoe trench the New Showing zone failed, and the property was again returned to Andy Horne.

"During the period 1977 to 1985 Cominco held the property and conducted extensive programs of geochemistry, geological mapping and diamond drilling. From 1978 to 1981 , 68 BQ boreholes were drilled totalling 6,823.4 metres. Exploration work concentrated


5

on the New Showing and Main Boulder Areas. Several other occurrences were also drill tested, notable the North Strat, Mist, and Raft Synform Occurrences. No work was reported on the property between 1981 and termination of the option agreement in 1 98 5. I'

GEOLOGY

The geology of the property is taken from Oliver's 1987 geological report.

"The property lies entirely within rocks of the Shuswap Meta- morphic complex. This metamorphic complex exists as an arcate belt of amphibolite facies metasediments and orthogneiss which extends North to Hobson Lake and continues in south easterly direction for at least 200 km's to the core of the Monashees (Okulith, A.V. 1979; Campbell, 1 9 6 3 ) . "

"Rocks of the Complex are characterized by highly deformed pelitic and carbonate assemblages frequently intruded by younger pegmatite and granitic gneiss, lesser marbles and quartzites. The internal stratigraphy of the metasediments appears more often than not, to be highly heterogeneous, and lithologic cor- relations within these packages are difficult to make with con- fidence. The deformed pelitic and carbonate assemblages typically conformably overlie much older gneiss domes. The latter have early Protozoic (Aphebian) ages with the overlying supra- crustrals generally dated at EoCambrian, 773 Ma (Hoy, 1 9 8 7 ) .

"The complex hosts several stratiform lead-zinc occurrences, notably Ruddock Creek, Cottenbelt, King Fissure, and Big Ledge. Although some differences do occur in the relative stratigraphy


6

and position of mineralization, in most deposits mineralization is associated with the development of clean marble horizons, often at the transition between platformal carbonates (calc silicates) and pelitic sediments (biotite almandine gneiss) (Fyles, 1970). Massive sulphides in most of these deposits are laterally extremely extensive, striking for several kilometres, but usually thin, averaging about a metre in true thickness. Metallurgically, zinc greatly exceeds lead, 5:1, and precious metals are poorly developed. All of them are true stratiform deposits and have been affected by the same deformational events as their enclosing rocks."

INDUCED POLARIZATION-RESISTIVITY SURVEY a) Instrumentation

The transmitter used for the induced polarization-resistivity survey was a Model IPT-1, manufactured by Phoenix Geophysics Ltd. of Markham, Ontario. It was powered by a 2.5 kw motor- generator, Model MG-2, also manufactured by Phoenix.

The receiver used was a model Mark IV manufactured by Huntec ( '70) Limited of Scarborough, Ontario. This is state-of-the-art equipment, with software-controlled functions, programmable through the front panel.

The Mark IV system is capable of time domain, frequency domain, and complex resistivity measurements.

I b) Theory

When a voltage is applied to the ground, electrical current flows, mainly in the electrolyte-filled capillaries within the


7

rock. If the capillaries also contain certain mineral particles that transport current by electrons (most sulphides, some oxides and graphite), then the ionic charges build up at the particle- electrolyte interface, positive ones where the current enters the particle and negative ones where it leaves. This accumula- tion of charge creates a voltage that tends to oppose the current flow across the interface. When the current is switched off, the created voltage slowly decreases as the accumulated ions diffuse back into the electrolyte. This type of induced polarization phenomena is known as electrode polarization.

A similar effect occurs if clay particles are present in the conducting medium. Charged clay particles attract oppositely- charged ions from the surrounding electrolyte; when the current stops, the ions slowly diffuse back to their equilibrium state. This process is known as membrane polarization and gives rise to induced polarization effects even in the absence of metallic- type conductors.

Most IP surveys are carried out by taking measurements in the time-domain" or the I' frequency-domain" .

Time-domain measurements involve sampling the waveform at inter- vals after the current is switched off, to derive a dimension- less parameter, the chargeability, "M" which is a measure of the strength of the induced polarization effect.

Measurements in the frequency-domain are based on the fact that the resistance produced at the electrolyte-charged particle interface decreases with increasing frequency. The difference between apparent resistivity readings at a high and low frequency is expressed as the percentage frequency effect, "PFE".


Transmitted Waveform I

Recorded Voltage

The quantity, apparent resistivity, Pa, computed from electrical survey results is only the true earth resistivity in a homo- genous sub-surface. When vertical (and lateral) variations in electrical properties occur, as they always will in the real world, the apparent resistivity will be influenced by the various layers, depending on their depth relative to the electrode spacing. A single reading cannot therefore be attributed to a particular depth.

The ability of the ground to transmit electricity is, in the absence of metallic-type conductors, almost completely depending on the volume, nature, and content of the pore space. Empirical relationships can be derived linking the formation resistivity to the pore water resistivity, as a function of porosity. Such a


9

~ formula is Archie's Law, which states (assuming complete saturation) in clean formations:

Ro = 0-2 Rw -

Where: Ro is formation resistivity RW is pore water resistivity 0 is porosity

Survey Procedure

The IP and resistivity measurements were taken in the time- domain mode using an 8-second square wave charge cycle (2- seconds positive charge, 2-seconds off, 2-seconds negative charge, 2-seconds off). The delay time used after the charge shuts off was 200 milliseconds and the integration time used was 1,500 milli-seconds divided into 10 windows.

The array chosen was the dipole-dipole shown as follows:

DIPOLE-DIPOLE ARRAY

n

Potential Electrodes

10

The dipole length ('av) was chosen to be 60 m for all lines. The 60-m, 200-ft lines were read from one to five or seven levels (Inv), to given a separation of 420 m and a maximum theoretical depth penetration of 200 to 250 m. A separate test line was run with a dipole separation of 10 metres and read from one to seven levels, to give a separation of 80 metres and a depth penetration of 35 to 45 metres.

The dipole-dipole array was chosen because of its symmetry resulting in a greater reliability in interpretation.

Stainless steel stakes were used for current electrodes. For the potential electrodes, metallic copper in copper sulphate solu- tion, in non-polarizing, unglazed, porcelain pots was used.

Readings were taken over 9 different lines as shown on the survey plan within MacFadyen and Rotzien's report, to give a total survey length of 9220 m.

d) Compilation of Data

The chargeability (IP) values are read directly from the instru- ment and no data processing is therefore required prior to plotting. The resistivity values are derived from current and voltage readings taken in the field. These values are combined with the geometrical factor appropriate for the dipole-dipole array, to compute the apparent resistivities.

The chargeability and resistivity data were each plotted in pseudosection form on maps 2 through to 10 for the test line and lines G1 to G8, respectively at at scale of 1:2,500. The chargeability data was then contoured at an interval of 10 msec, and the resistivity data at a logarithmic interval of base 10

ohm-m.

DISCUSSION OF RESULTS

T e s t L i n e

The test line runs east-west across the north showing. A strong resistivity (low) anomalous curves across the western edge of the pseudosection, and correlates closely with some very strong I.P. responses. This anomaly could be caused by a minor fold of mineralized strata. From examining the geology map of this area, the test line was run over an area of known outcrops of calc-silicates and siliceous biotite gneisses. Little correla- tion is seen between the pseudosection resistivities and those from Scott's drill hole sample geophysical test results. This suggests that the drill-hole results cannot be used for any concrete interpretation of the pseudosections, but rather as a guide only. Geological data of drill hole results over an I.P. line would produce geological data better suited as an inter- pretative aid.

L i n e s G1 to 6 8

The most notable anomaly is resistivity anomaly A, which apparently outcrops on line G2 at 16+20E. Anomaly A can be traced from line G2 to line G8, and possibly as far south as line G6, for a strike length of 2400 to 3900 metres. Line G2, being the longest line, gives a good overall impression of the geophysical responses. The area on line G2 between anomalies A and B shows much variation in resistivities and chargeabilities.

The observed resistivity values from the survey under discussion do not agree with the measured values from a 1979 survey by Alan Scott (see Appendix 1 ) . A possible explanation for this could be stress fracturing within the marbles and calc-silicates


12

caused by the amount of known folding, faulting, and intruding of igneous rocks across the property. It must be remembered, also, that Scott's results are based upon only a few selected samples taken from drill cores and are therefore quite biased. It is assumed that the samples tested were, for the most part, unfractured and possibly dry.

Resistivity Anomaly A is an easterly-dipping, near-linear resistivity low, characterized by an underlying near-linear resistivity high zone, and an overlying, limited, non-linear resistivity high zone. While the underlying resistivity high occurs beneath every survey line, the overlying resistivity high nearly dis- appears or becomes weaker on several of the lines. The average resistivity value of anomaly A is approximately 400 ohmmetres, and is often less than 150 ohm-metres on some survey lines.

Anomaly A correlates with a small topographic depression between two moderate highs - a feature which is consistent across most survey lines. The chargeability values correlating with anomaly A are moderate, showing values between 30 and 4 0 msec, and suggest that the causative source of anomaly A could be a mineralized shear or fracture zone.

Anomaly A could reflect the contact zone between the biotite gneisses on its east side, and another rock unit on its west side. This hypothesis is supported by the contrasts in resistivities and chargeabilities on line G2. That pseudosection has lower resistivities and chargeabilities to the east of anomaly A, and shows less features. From the geological map, the east side of the pseudosection for line G2 corresponds to an area of mapped marble and calc-silicates. The moderate resistivity values for the rest of the lines south of G2 suggest that gneisses are the probable cause.

I 13

Resistivity Anomaly B is an easterly-dipping resistivity low which occurs at the western end of line G2. This anomaly is underlain by a very strong resistivity high which ranges from 3547 to 10134 ohm-metres as it curves up to form a topographic rise at the surface. Anomaly B occurs at the western edge of a wide topographic depression, and correlates with a good chargeability anomaly which ranges from 35 msec at level 1 , to 86 msec at level 7. The causative source of this anomaly could be mineralized pegmatite or a mineralized shear zone, both of which have very low resistivities and very high chargeabilities. The linear nature of the anomalies and their strong responses at depth suggest that the causative sources are both structurally controlled and have good depth extent.

Resistivity Anomaly C is a strong anomalous linear resistivity high dipping steeply eastward which correlates with a topographic rise immediately east of anomaly B and between 6+00E and 7+00E. The resistivity values range from 2702 to 5218 ohm- metres and correlate with moderate chargeability values averaging approximately 30 msec. The deep resistivity response suggests that the causative source is structurally controlled, and could be an intrusive. The causative source of this anomaly could be biotite gneiss, which can exhibit similar geophysical values and is seen to outcrop within this area. However, pegmatites typically have much higher resistivities than biotite gneiss, agreeing with the high values attributed to anomaly C. The topographic high associated with this anomaly supports the conclusion that a more resistive rock type is the causative source. A narrow, weak, and near linear anomalous resistivity/ chargeability low dipping westerly cutting through anomaly C and outcropping near 9+00E could reflect a younger unmineralized fracture zone cutting through anomaly C.

GEOTRONICS SURVEYS LTD .I

14

Resistivity/Chargeability Anomaly D is a moderate, steeply easterly-dipping anomaly occurring between anomalies A and C, and outcropping near 13+80E. The resistivity values range from 3 3 3 to 7 1 3 ohm-metres, while the chargeabilities vary from 46

msec at level n=l to a high of 124 msec at level n=7. The low resistivities do not have a linear nature as well defined as anomalies A or B, and so they could reflect fractured rock. The high chargeabilities suggest an increasing concentration of sulphides with depth.

The area between 9+60E and 13+20E shows resistivities from surface to depth in the range of 2500 to 7900 ohm-metres correlating with outcrops of biotite gneiss (units 9 & l o ) , and marble (unit 5 ) , as well as some small outcrops of the pegmatites (unit 3 ) . These three rock types have very high resistivities, and therefore most likely collectively cause the high responses in this area. From examining the geology map, line G2 could strike along the contact between the marble and calc-silicates on its north side, and the biotites on its south side. This could ex- plain why the zone of high resistivities widens towards the surface. However, a near-linear zone of high chargeability averaging approximately 50 msec and reaching 64 msec at depth dips- westerly along the lower half of the resistivity high, and immediately below a weak sub-linear resistivity low which could reflect a narrow fracture zone. This relation could reflect sulphides overlying a highly resistive bed of marble or calc- silicates. These sulphides could be structurally controlled by a minor fracture or fault outcropping near 12+10E which paral- lels that which outcrops at 9+00E.

Chargeability highs on this property often occur at depth along many of the lines as far south as line G6. One chargeability anomaly in particular occurs west of, and below, anomaly A and apparently dips mildly to deeply easterly. This anomaly corre-


15

lates closely with resistivity anomaly D on line G2, though anomaly D does not appear on any lines further south. This chargeability anomaly suggests the presence of sulphides in varying concentrations, most often at depth. While the

character of each successive pseudosection assists in determining the continuity of major anomalies, the distance separa- ting the pseudosections, and the short length of each (over the scale of this survey), work against this interpretation. For

these reasons, determining the continuity of the chargeability anomalies in particular is very difficult.
