4 FLY CLAMS NTRODUCTON The Fly claims are located just east of Highway 97 at 2 Mile House. Access is either off the highway or from a gravel road that follows Mile Creek from the highway east. The Fly to 22 claims were staked on June 30, 973 and Fly 23 to 32 on July 22, 973 by W. Spilsbury for Union Miniere Explorations and Mining Corporation Limited. An induced polarization and resistivity survey was done $ 4 from July 3 to August 7, 973. The.P. crew chief was Mr. H. Holm and the project geologist was Mr. P.P. Master, who were responsible to Mr. A. Burgoyne, P.Eng. GEOLOGY The claims are mostly underlain by Pleistocene glacial overburden and Tertiary volcanic cap rock. GRD CONTROL Qu For the survey, the claim lines were used. The northern tip of Soda Lake was used as a reference point (line 5N, SW). The lines are (true) east to west with stations flagged and chained every 00 feet. A minimum of blazing and axecutting was done. NDUCED P~LAR~ZATON AND RESSTVTY SURVEYS 0 Field Procedures McPhar model P 660 frequency domain induced polarization equipment has been employed in this survey. The transmitter operated on a constant alternating current output of approximately amperes depending on electrode contact resistance, and the two current frequencies used were.325 and 5.0 hz. Power for the transmitter was supplied by a motor generator with a rating of.0 kilowatts and an output of 25 volts. The receiver was of a remote variety which determined the resistivity at 5.0 hz as a detected volt- age, and, as a second operation, compared the change in resistivity at 5.0 hz and.325 hz by measuring the change in voltage. This change is a measure of the induced polarization phenomenon, termed the apparent Frequency Effect

7 2 (in X). The definition of this parameter is as follows: - fa.325 hz. - Pa 5. Ohz F.E. (ai - Pa 5.0 hr where Pa is resistivity. The most common array used with the frequency domain technique, the dipole-dipole array was utilized on this survey since it provides both the advantages of low inductive coupling and symmetrical anomalies. n the field, measurements are made as follows. Current is applied to the ground at two points a distance (X) apart. Potential differences are measured at two other points (X) feet apart, in line with current electrodes but separated from it by an integer, number of times (N) times the basic distance (X). n this survey the electrode separation (X) equalled 400 feet for N *, 2, and in places for N =, 2, 3, 4. High current electrode contact resistances were overcome by utilizing aluminum foil soaked in brine solution as electrodes. Non-polarizing porous pots were used for the detection of potential differences. Data Processing and Presentation of Results The voltage detected by the receiver at the higher frequency were. recorded along with the constant current output of the transmitter and the apparent resistivity in ohm-feet/2 TT calculated using the following formula: -.=- Pa 2rr (G.X) c, where V is the detected voltage in volts is the current output of the transmitter in amperes X is the dipole electrode separation G is a constant function of the geometry of the array: for N =, G = 3, N = 2, G = 2... The apparent Frequency Effect is measured directly from the receiver as in the section on Field Procedures. Another quantity utilized in the presentation is a normalized parameter called the apparent Metal Factor. Since the measurement of the degree of polarization is related to the apparent resistivity of a rock mass, this

The Metal Factor is obtained by normalizing the apparent Frequency Effect for varying resistivities. n presenting the results, the three parameters are plotted at the intersection of grid lines for each set of electrode positions, one from the center point of- the current electrodes and the other from the center point - of the potential electrodes (see Figure 2). n general, the plots are designated as pseudo-sections and not true depth sections. The separation between sender and receiver electrodes is only one factor which determines the depth to which the ground is being sampled for any measurement. The operator for the induced polarization and resistivity surveys was H. Holm. Helpers included W. Bepple, P. Wong and R. Lancaster. nduced polarization surveys covered line 20N from 6W to 25W, line 35N from 6W to 20W, line 50N from 9W to 2W and line 65N from 7W to 2W, a total of 37,400 line feet or 7.08 line miles. Lines 20N and 50N are claim lines while lines 5N, 35N and 65N are spaced 500 feet on either side of the claim lines. (See Figure 3). No significant results were obtained. CONCLUSONS AND RECOMMENDATONS Most of the results show very low chargeability effects and relatively high resistivities. Due to lack of rock outcrop no clear-cut interpretation of the induced polarization and resistivity effects can be made. No further work is recommended on this part of the claims.
