2 PHONE r otf,,nm PHONE HO EM WAGNER-MILLS GEOPHYSICAL SURUEVS TORONTO, CANADA SUITE 4oi, 62 RICHMOND ST. WEST GENTLEMEN: WE HAVE COMPLETED THE MAGNETOMETER SURVEY OVER THAT PART OF THE AREA COVEkED BY GULL LAKE. THE PROPERTY IS SITUATED IN SCHOLES TOWNSHIP, ONTARIO, CONSISTING OF THE FOLLOWING CLAIMS* T 1* T U702I T 1* T 1*6599 METHODS AND RESULTS OF THE SURVEY A SCHMIDT-TYPE MAGNETOMETER WAS USED MEASURING THE VERTICAL COMPONENT OF THE ANOMALOUS MAGNETIC FIELD. THE SENSITIVITY OF THE INSTRUMENT IS ABOUT (PLUS OR MINUS) 2.5 GAMMAS. THE OBJECT or THE SURVEY WAS TO FIND THE CONTIN UOUS EXTENSION OF THE MAGNETIC ANOMALIES/ AS LOCATED ON THE LAND BY PROSPECTING GEOPHYSICS LIMITED IN 1959* T 0 T HE A RtA COVERED BY THE LAKE. FOR THIS THE FRAME OF REFERENCE OF THE PREVIOUS SURVEY WAS ADOPTED IN THE PRESENT WORK AND AFTER THE CORRECTIONS HAD BEEN MADE, EACH LINE WAS ADJUSTED TO OBTAIN SMOOTH CONTINUITY. THE FAC., THAT THE AMOUNT OF THE NECESSARY ADJ"STMENT DID NEVER EXCEED 100 GAMMAS REFLECTS FAVOURABLY ON THE ACCURACY OF BOTH SURVEYS. THE RESULTS or BOTH SURVEYS ARE COMPRISED IN THE SUBMITTED MAGNETIC CONTOUR MAP DRAWN TO A SCALE OF l" r 300 FT. AND FEATURING A CONTOUR INTERVAL OF 1000 GAMMAS. INTERPRETATION THE PREDOMINANT PATTERN OF THE MAGNETIC CONTOUR MAP IS THAT OF. LARGE, NEARLY ISOCLINAL FOLD, WITH AXIAL PLANE STRIKING N 55 E APPROXIMATELY. THE MAGNETIC MATERIAL FORMING THIS STRUCTURE WAS- X NEAR UN l FORM THl CKNESS OF ABOUT 350 FEET ON THE NORTHERN AND ABOUT 650 FEET ON THi SOUTHERN LIMB, AND A UNIFORMLY HIGH DIP OF Afco'UT JJQ?.

3 - 2 - THERE ARE A NUMBER OF SMALL FEATURES APPARENT, SUPERIMPOSED ON THE MAIN PATTERN, SUCH ASt (i) LOCALIZED MAGNETIC HIGHS ON THE NORTHERN LIMB SUGGEST IN HOMOGENITY IN THE MAGNETIC MATERIAL OR MORE LIKELY, A COCAL VARIATION OF DEPTH. (M) DISCONTINUITY IN THE PATTERN SUCH AS AT LINE 8E AND THE NORTHERN PART OF LINES *)6E A ND 50E SUGGEST DISCONTINUITY OF THE MAIN STRUCTURE, CROSS STRUCTURES AND/OR DISPLACEMENTS. (MI) THERE ^NUMEROUS EVIDENCES or SOME MINOR PARALLEL MAGNETIC FORMATIONS CONFINED TO SMALLER AREAS. ALL THESE MINOR FEATURES ARE CHIEFLY APPARENT ON THE NORTHERN PART OF THE AREA WHERE THE RELATIVE SMALLER DEPTH FROM THE SURFACE TO THE MAGNETIC MATERIAL ALLOWS A BETTER RESOLUTION BUT THEY MAY EXIST IN A SIMILAR WAY ON THE SOUTH. NUMBERICAL ANALYSIS OF THE RESULTS YIELDED THE FOLLOWING ESTIMATIONS! IN THE VICINITY OF THE NORTHERN PART OF LINE 48E THE DEPTH TO THE MAIN MASS IS ABOUT 2^0 FT. IN THE VICINITY OF LINE ~]2L, SOUTH OF THE BASELINE, THE DEPTH IS ABOUT ^50 FT. THE DEPTH ESTIMATION CAN BE TAKEN TO EXPRESS LOWER LIMITING VALUES, OR MINIMUM DEPTH. CORRELATION WITH AEROMAGNETIC MAP TENDS TO DIS PROVE THE CONCEPT OF ONE DISTINCT FOLDED STRUCTURE. IT SUGGESTS A MAJOR FOLD FORMED BY \HE SOUTHERN LIMB OF THE PRESENT PATTERN WHICH APPEARS TO BC CONTINUOUS AS FAR AS JOAN LAKE AND IS JOINED THERE BY THE MAGNETIC FORMATION EXTENDING FROM THE NORTH END OF CUMMINGS LAKE. IN THIS LARGER FOLDED STRUCTURE THE MAGNETIC TREND NORTH OF THE BASELINE WOULD BE JUST ONE OF THE MINOR PARALLEL CROSS FEATURES - OR STRUCTURES EASILY RE COGNIZABLE ON THE AEROMAGNETIC MAP. THIS CONCEPT IS SUPPORTED BY THE FACT THAT THE GROUND MAGNETIC ANOMALY SEEMS TO EXTEND WITH A SMALLER INTENSITY BEYOND THE SUPPOSED NOSE OF THE FOLD AS A CONTINUATION OF THE LOWER LIMB.
