5 Page 3 NTRODUCTON: LOCAT ON : ACCESS : A ground magnetometer survey was completed over all SYLVA claims along flagged grid lines 150 metres apart from July 24 to September 19, The SYLVA claims are located about six miles west of Twinkle Lake along the BERG road sixty road miles SW of Houston, B.C. at 53'17'N, 127"07'W, NTS 93 E/14. Access is via sixty miles of forestry access gravel road from Houston, B.C., to Twinkle Lake, then about six miles west along a 4-wheel drive road to the property. Approximately 9000 feet of rough trail was prepared by bulldozer for drill access. CHAN AND COMPASS GRD: A control grid of approximately 30 1 ine-km. was established on the SYLVA claims by means of a chain and compass survey. East-west lines were flagged 150 metres apart, with station spacings measured at 30 L metre intervals. MAGNETOMETER SURVEY: A, nstrumentation A proton precession magnetometer model was used for the survey. The total field is measured to the nearest 10 gammas with the sensing bottle carried on the surveyor's back. Method of Survey Base stations were established at 150 metre intervals along the control grid base line (50t00W) so that diurnal drift corrections and daily variations in the magnetic field could be made. Readings were taken during the survey at these base stations at intervals not exceeding two hours, and usually less than one hour. Three readings were taken at each station 30 metres apart along the flagged lines 150 metres apart. The readings were averaged and corrected for diurnal dri ft and dai ly variations. The corrected values in gammas were plotted on the accompanying map. M.L. Legros and 3. Bennett conducted the survey.

6 Page 4 C. nterpretation Add 56,000 gammas to the values on the map to obtain the total intensity at each station. The values were contoured with a 500 gamma contour interval. Several one to four station highs reached over 4000 gammas. No pattern appears to be associated with these high values. Outcrops in the area consistently carry minor amounts of disseminated magnetite, not usually visible, but djscerni ble with a magnet. The more abundant spot highs in the east central part of the area are related to weakly magnetic - tuffaceous vol cani cs. GH: kdl G..
