Included </p><p>here is the location and present holders of the property,instruments </p><p>used,with a brief explaination of field procedures,previous surveys </p><p>done on the property,and finally an interpretation of the results. </p><p>Also enclosed with this report are seperate profiles of each </p><p>line,as well as a complete map of each survey.</p></li><li><p>-2-</p><p>HOLDERS of CLAIMS; The, report presented here was written by </p><p>the technical personal of the Cayuga Syndicate,which is </p><p>headquartered at 360 Main St. ,V/innipeg,Manitoba. This organization </p><p>are the present holders of this property.</p><p>LOCATION: The claims surveyed are located in the north-east </p><p>sector of Vincent Township(NTS Map 42E12) and are registered as </p><p>#8/15986 to #845990 respectively,within the Thunder Bay Mining </p><p>District(Fig.l). The claims are accessible by way of Highway #11 and </p><p>various foot trails.</p><p>EQUIPMENT and PROCEDURE; The geophysical methods used on </p><p>these claims were of the reconnaissance type,that is ground based </p><p>magnetometer and VLF-EM. The surveys were conducted between June </p><p>and August 1986.</p><p>The instruments used were a Geometrics portable proton </p><p>magnetometer,model G-8l6 and a Geonics EM16 VLF-EM system. </p><p>Specifications for both instruments are given in figures 2 and 3. </p><p>A Geometrics G-856B portable magnetometer was used as a magnetic </p><p>base station.</p><p>As this report is concerned basically with recording data </p><p>for assessment purposes,no attempt will be made to probe the </p><p>theoretical aspects of the Magnetic or Electromagnetic methodology </p><p>or equipment design. A list of suitable references is supplied to </p><p>the reader wishing to pursue this line of thought.</p><p>A brief procedure used in these surveys is as follows. </p><p>For the magnetic survey,the first step is to get the base station </p><p>functioning. The base station is necessary to correct for diurnal </p><p>and micropulsation time variations. The base station is tuned in</p><p>order to acquire the best magnetic signal. This magnetic base was</p></li><li><p>-3-</p><p>found to be 60300 Gammas. The sychronization of the base clock </p><p>with the operators field clock and a time interval for readings </p><p>is then established. This interval was 60 seconds. Finally the </p><p>Auto switch is activated and the diurnal station monitor is </p><p>operational. The operator then proceeds down the line,takes and </p><p>records a reading at the station to the nearest minute. The </p><p>stations are at 25 meter intervals along north-south trending </p><p>lines,which are 100 meters apart. The total number of stations </p><p>for all five claims is 331.</p><p>The VLF-EM survey is performed by first orientating the </p><p>instrument perpendicular to the survey line in order to establish </p><p>a transmitting station for the best coupling effect. In this case </p><p>the transmitter is NAA originating from Cutler,Maine at a </p><p>frequency of 2^.0 kHz. The transmitter direction is determined </p><p>when the sound intensity is at a minimum. The next move is to </p><p>orientate the reference coil along magnetic lines,by slowly </p><p>moving the instrument back and forth until minimum sound intensity </p><p>and adjust the Out of Phase(Quadrature) component dial to further </p><p>minimize the sound. Read and record the number on the inclinometer </p><p>and the Out of Phase component dial. The operator must always face </p><p>north or in the case of north-south trending strike,one must face </p><p>west. This is necessary in order for the polarities to remain </p><p>constant through every line.</p><p>PREVIOUS WORK: As far as can be ascertained no published </p><p>evidence is available of prior work executed on these particular </p><p>claims. In the field however,there is evidence that some trenching </p><p>was done some time ago.</p></li><li><p>-i).-</p><p>I INTERPRETATION; The magnetic profiles (Fig. 4-2?) indicate </p><p>in general,a low magnetic response. There are points which show </p><p>major peaks both high and low. The magnetic anomalies that are </p><p>present imply that the structure causing them,is narrow and steeply </p><p>dipping. The structure seems to trend along strike,that is in a </p><p>east-west direction and is located,in general between lines 0+00 </p><p>and 18+00 West,covering a width of 100 meters,from stations 0+00 </p><p>to 1+00 South. There is a southern magnetic anomaly located between </p><p>stations 4+00 and 5+00 South,along lines 18+00 to 23+00 West. The </p><p>magnetic anomalies do not correspond exactly to the VLF conductors </p><p>noted below,but they are adjacent and thus they are most likly the </p><p>result of the same geological structure.</p><p>The VLF survey shows two conductive bodies trending </p><p>roughly in a east-west direction. The northern response is found </p><p>from line 0+00 and trends north-westerly to line 18+00 West and </p><p>probably continues further beyond the boundary of these claims in </p><p>the same general direction. This conductor seems to weaken toward </p><p>the eastern portion of the property.</p><p>The southern conductor is found between lines 14+00 </p><p>and 23+00 West (Fig.28-43). It trends in a east-west direction and </p><p>most likly continues further east. The two conductors are </p><p>approximately 200 meters apart. These conductors are very similar </p><p>in response,in that both the Inphase and Out Phase components show </p><p>in general,a complementary repetative pattern through all lines. The </p><p>profiles also suggest that the dip of the southern conducting </p><p>structure is relatively steep and to the north. The response </p><p>signal is in general of moderate strength and sharp,hinting at a </p><p>shallow structure in depth. The northern conductor has relatively</p></li><li><p>-5-</p><p>physical characteristics as the southern response,implying </p><p>that both conductors are the result of parallel geologic features. </p><p>From the geological evidence,there seems to be,contained </p><p>within the volcanic flows a thin belt of Iron Formation. This zone </p><p>is observable at random locations on surface between line 10+00 and </p><p>17+00 West and approximatly between stations 50 to 100 South. This </p><p>formation contains some sulphides but its magnetic susceptibility </p><p>is low. A few meters south of these exposures is found,again at </p><p>random shear zones containing up to 53d pyrite. These shear zones </p><p>are in line with an apparent topographic lineament. Both of these </p><p>structures may account for the geophysical responses encountered </p><p>on the northern portion of these claims. Therefore a possible fault </p><p>structure trending in general in a east-west direction maybe </p><p>contained within this property.</p><p>The southern conductor is not quite as obvious. Some </p><p>Carbonized Iron rich rock was observed near station J++00 South on </p><p>line 16+00 West. This may have some strike length to it. There are </p><p>also many intrusive rocks within this southern region,and the </p><p>anomaly may be a result of a lithological change.</p><p>CONCLUSIONS; The anomalous zones within these claims </p><p>will be explored in more detail in up coming field seasons. This </p><p>v/ill involve trenching and X-ray drilling. It seems however that </p><p>a major concentration of economic minerals is not likly in this </p><p>type of environment,as the large discoveries seem to occur in </p><p>general near volcanic-sedimentary contacts. This property is near </p><p>some major showings and it is for this reason that it v/ill also be </p><p>examined in future exploration programs.</p><p>Respectively Submitted</p></li><li><p>2M</p><p>4w4^^^^ * G^V^VmS' i</p><p>Scale: l cm. s 7.84 M.(A) .s 13.7 km.,___________ ^"'^ J1 fX * j.......*""* \ J-^J1 ri r ___ __ __ JBJ.</p><p>showing position of Vincent Township J ~ Mining district and location of claims </p><p>[within, township. ^^^^</p><p>Map within</p><p>(B)</p></li><li><p>Fig 2</p><p>SPECIFICATIONS</p><p>Sensitivity: 1 gamma throughout range</p><p>Range: 20,000 to 90,000 gammas (worldwide)</p><p>Tuning: Multi-position switch with signal amplitude indi cator light on display</p><p>Gradient Exceeds 300 gammas/ft (increased gradient to!- Tolerance: erance to 800 gammas/ft upon request)</p><p>Sampling Rate: Manual push-button, one reading each 6 seconds</p><p>Output: 5 digit numeric display with readout directly in gammas</p><p>Power Requirements:</p><p>Temperature Range:</p><p>Accuracy (Total Field):</p><p>Twelve self-contained 1.5 volt "O" cell, univer sally available flashlight-type batteries.
