2 i j R. A. MACGREGOR, P.ENG. PAGE NO. l In t r odu c t ion Report on Magnetometer and VLF-EM Survey Part of Lots l to 6, Concessions 5 and 6 f Skead Township, Ontario - Linecutting, followed by J4aanetometer and VLF-EM surveys were carried out at various tiroes between August and November at three localities in Concession 5 and 6, Skead Townshin. Ontario. The results are shown on three separate sheets. Location, Access and Ownership The claims (w) are located in lots l to 6 Concession 5 and lots 2 to 4 Concession 6 Skead Township. District of Temiskaming, Ontario. Claim numbers are L , , , , 4O1398-JG008*, inclusive. The Claims are recorded in the name of R,A. Macgregor, 134 Palace Dr. Sault Ste. Marie, Ontario and L. Lacasse, Larder Lake, Ontario. Access is from Highway 624 which crosses the property about 9 miles south of Larder Lake, Ontario. Previous Exploration In previous exploration a shaft was sunk about 30 feet on claim L400703, and some surface pits sunk at various places throughout the area. An airborne magnetomer survey has been flown over the area and some ground magnetometer work done in the area of sheet 3 in the past. Gold is reported from the 30 foot shaft. A large part of the claims are covered by drift, Geology The property is underlain by a volcanic sequence of rocks, mostly mafic volcanics with narrow felsic volcanic bands. Through the north part is a belt of ultramafic rocks, mostly serpentinized peridotite, which may also be altered volcanic flows. Much of the property, particularly the ultramafics as outlined by the high magnetics are covered by overburden. Survey Procedure Base and tie lines were extended from adjoining claims on which lines had been previously cut. Cross lines were then run at 400 foot intervals normal to the base lines. S ome..qjl,tllfi. JL ine S. we re recutting of lines cut in the winter a few years ano. All lines were chained and picketed at 100 foot intervals. 3-y,

3 R. A. MACGREGOR, P.ENG. PAGE NO. 2 Magnetometer readings were taken with a Sharpe - uxg ignetometer at 50 foot intervals. The looping method was used for control of diurinal variation."?n this method a base station is selected and readings taken alona lines describing a loop, arriving back at the starting base station in less than two hours. A second loop is then started using either the sane base station or another which is tied to the previous loop. Readings are then corrected for diurinal variation by assuming the tine between readings is the same and distributing any variat.ron equally among the intervening readings. No reading!" correction was applied less " than " the accuracy of the "~""' base station ' A VLF-EM. survey^was carried out using a Crone Radem.. set to the signal from Cutler. Maine (17.8 KHp). Readings were taken at 100 foot intervals usina the procoditre outlined in Appendix JE, The looping method was used for control of variation, the same as described for the maanetometer survey excepting that the time was noted for each station. Results and Conclusions Magnetometer The magnetics outline the ultramafics which appear to occur more as discontinuous lenses than as a uniform sill. The magnetics also show the trend of the volcanic flows. Jfost north of the old Fidelity shaft on Sheet 2 is a narrow high magnetic band which could be a narrow iron formation. In the west part of Sheet 3 high magnetic readings indicate an ultramafic band which trends northeasterly rather than the usual northwesterly trend. Faulting may be the cause, but the area is entirely covered by overburden. The VLF-EM survey shows a number of cross-overs which extend across several lines and are possibly caused by faults or conductive overburden. The west part of sheet 3 contains no strong cross-overs possibly due to the depth of overburden, A number of strong single line cross-overs are worth checking by other geophysical methods, They are: Sheet 1: Line 100W, 5 -f 00 S and 9 -f 20S Sheet 2: Sheet 3: M on Line 48W 15 * 4ON on Line 60W N on Line 24E from South tie line 3 * SON on Line 8E from South tie line possibly extending to line 12E All the areas are drift covered, Respect^uMy submitted, R,A, MacHregoi#vP,Eng
