PROSPECTING GEOPHYSICS LTD. REPORT GEOPHYSICAL SURVEYS ON PROPERTY OF GOLIATH MINES LT17. BENOIT TOWNSHIP, ONTARIO INTRODUCTION Goliath Mines Ltd. holds a 320 acre gold-bearing property in Benoit Tovmship, Kirkland Lake Gold Mining Area, Ontario. Previous v;ork has largely consisted of underground development and sampling of a gold-bearing zone of quartz and schist. Apparently, no surface exploration has been carried out on the property for lateral extensions on the gold-bearing zone or for possible parallel structures. As a result, geophysical surveys, consisting of V.L.F. (very low frequency) electromagnetic and magnetic surveys, have been completed over the property, prior to a diamond drilling programme. The follovung report and accompanying maps describe the results of the surveys. PROPERTY The property includes eight (S) contiguous claims in Lots 9 and 10 of the south half of Concession II, Benoit Tovmship, Ontario. The claims are registered as follov/s: L511463 L5H469 L5H467
PROSPECTING GEOPHYSICS LTD. - 2 - PROPERTY (cont'd) L57H63 L545707 L545710 L5457H L545712 The property is readily accessible by road as Highway 11 is situated along the west boundary. GEOLOGY The geology of the area is described by H. L. Lovell, 1971, in Geological Report 92 by The Ontario Department of Mines and Northern Affairs. The rocks in the area are predominantly volcanic, interbedded with some fine-grained sediments and tuff. The dominant intrusives in the area range from mafic to ultramafic rocks. The major fold in the area is a syncline, the axis of v;hich plunges from the northern part of Black Township, southeastward across Benoit Township. The volcanics have been tightly folded along the synclinal axis and the regional trend of the volcanic assemblage follows the northwest strike of the axis. However, locally, at the axis of the fold, they may strike northerly. Most shear zones of particular significance in the search for gold, strike north to northwest. On the Goliath
PROSPECTING GEOPHYSICS LTD. GEOLOGY (Cont'd) property, a gold-bearing zone, consisting of quartz and chlorite schist, has been partially developed underground by previous owners. This was in the period 1917 to 1920 with some additional sampling in 1936 when the workings were dev:atered. On the basis of this latter sampling, which included the milling of a 110 ton bulk sample, H. F. Knutson, Mine Manager, calculated an ore reserve of 97,963 tons grading 0.423 oz. gold per ton. SURVEY KETHODS AND INSTRUMENT DATA The geophysical surveys were carried out over a network of east-west lines at 300 foot intervals as shown on the accompanying maps. The equipment used in the V.L.F. electromagnetic survey was the Geonics E.M. - l6 system. The V.L.F. method uses the radiation from powerful military radio transmitters at low frequencies as primary signals as opposed to portable transmitters in the conventional E.II. methods. The instru ment hac tv:o receiving coils and the parameters measured are: (1) The vertical in-phase component. (2) The vertical out-of-phase component. ( quadrature coraponent) The interpretation of the results uses the relative measurements cf these two parameters and it is possible to outline such poor conductors as sheared contacts, breccia zones, faults, and alteration zones, as well as the good
PROSPECTING GEOPHYSICS LTD, SURVEY I-:STHODS AHD INSTRUMENT DATA (cont'd) sulphide conductors. Because V.L.F. anomalies are produced by a wide range of geological affects, profiles tend to show a complex "clattered" pattern and additional assistance is required to distinguish trends. By the use of the Fraser method of filtering tilt angle profiles, the readings are converted into contourable data and it is that data that are plotted on the accompanying map No. 1. The magnetic survey v:as carried out over the same net work of lines using an I1F - 2 Fluxgate magnetometer. The magnetometer measures the vertical component of the earth's magnetic field. Readings were taken at 100 foot intervals with some detail readings at 50 foot intervals. These are plotted as gammas on a separate map No. 2 after correction for diurnal variation. All conductor ax6s have been plotted on the magnetic map to aid in the interpretation. RESULTS OF THE GEOPHYSICAL SURVEYS A. El e c t r orna gn e t ic Surve3''; The results of the electromagnetic survey are shown on r.ap ITo. 1. An examination of the map shows a number of conductive zones with a general north to northwest strike. The major conductors are lettered A, B, C, etc., for reference purposes and are described below: Zone "A" is a north striking conductor that is caused by the power line along Highway 11.
PROSPECTING GEOPHYSICS LTD. -5- Zone "B" is likevd.se a surficial conductor that represents the Trans-Canada Pipe Line. Zone "C" is a northwest trending conductor v,rith an apparent dip to the west. The zone has a length of approximately 1,300 feet and is located about 300 feet v.'est of the shaft which was put down to develop the gold-bearing zone. The conductor, nore or less, parallels the river but continues northwards beyond the bend in the river where there appears to be 3or;-e faulting. This zone may well represent a shear zone and could be related to the gold-bearing zone developed underground. Zone "D" is a fairly strong north trending conductor situated some 700 feet east of the shaft. It has a length of approximately 1,600 feet but there is a distinct possibility that Zone "E^" is a faulted extension to the north. There is a hydro line trending northwest across these zones which may exaggerate sone of the readings but, there seems little doubt that they represent conductive z ones i n the underlying rocks. The conductivity of the zone is within the range of a shear zone. Zone "F" rr.ay well be the northerly extension of "C" zone and the change in trend nay be due to the influence of the hydro line on line 27M.
PROSPECTING GEOPHYSICS LTD. Zone "G" is a v.'eal: northwest trending conductor v:hich has its strongest portion at the south boundary of the property v.'hcre it continues to the south. B* Magnet i c Survey ; An examination of nap!!o. 2 with the magnetic survey results, shows a well-defined northv:est trending anomaly in the western half of the property. The readings in this portion, range from 1,000 to over 5^000 gammas as compared to 700 to 1,000 gammas in the eastern portion of the property. There seems little doubt that the anomaly represents a different rock formation, probably a more basic volcanic formation or possibly an intrusive. The eastern portion represents r.ore felsic volcanics such as rhyolite interbedded vat h tuffs. The major conductive cones, "C", "D", "E" and "F" are within the felsic volcanic assemblage, whereas "G" zone is within the magnetic anomaly near the contact. The conductor appears to parallel the contact. '!3 A::D RS The geophysical surveys outlined several conductive zones in the proximity of the known gold-bearing zone developed underground. One of these conductors referred to as "C" zone, may possibly be related to the gold-bearing zone.
PROSPECTING GEOPHYSICS LTD. - 7 - All of these zones show conductivity within the range of shear zones and thus warrant further investigation. The results should be closely correlated with all information available on the known gold-bearing zone, prior to a drilling programme. This could aid in providing priorities for drilling and such a programme should also include some holes to investigate the depth extension of the known gold-bearing zone, Respectfully submitted, PROSPECTING GEOPHYSICS LTD, Montreal, Quebec November 30, 196*0 H. *3.
