Det ble også målt i 3 borhull, nr 998/00, 1000/00 og 1001/00. Det ble registrert 3 ledere: Nr. 1 og 2 faller sammen med tidligere slingramledere og er knyttet til hhv skifrig (rød) sone og i gneisene. Den tredje finnes på intrusjonskanten (grafittskifer, kalkskifer) under borhull 1001/00. Østenfor dette hullet ligger en indikasjon som anbefales undersokes videre.

3 REPORT Risto Pietilå GENERAL Fixed loop protem survey was carried out at Nikkel og Olivin mine site in order to "sterilize" certain part of the western contact area. Both down hole and ground surveys were implemented. 2 SURVEY PARAMETERS Fig. 1 shows the loop layout and surface lines. Same transmitter loop was used for down hole survey as well. Surveyed holes are listed in Table 1. II, ' Hole Y X ' z ' Di Azim Len th " Table.1. Ground surveys were carried out according to Table 2. Line 1300N 1400N 1850E 2200E From 1700E 1000N 1100N Table. 2. To 2500E 1600N 1700N Transmitter loop coordinates are 1700E-2100E and 1200N-1600N (400 by 400 m). Station interval used in ground survey was 25 m and in down hole survey 5 m/2.5 m respectively. Transmitter current was 14.9 A. 3 INTERPRETATION 3.1. Ground surve Figure 2. shows the location of conductors plotted on the slingram map. Conductors 1 and 2 coincide with slingram data signifying that the conductors are close to the surface. Conductor number 3 is approx. at 100 m depth hence being beyond the detection depth of the Max-Min. Conductor skiffer". 1 is related to the regional, conductive zone known as "rod

4 otab`okumpu REPORT Risto Pietilä Conductor 2 is in the gneiss area outside the surface boundary of the intrusion. This conductor has not been sampled or drilled during previous exploration projects. Hole P2 (drilled 1996) collared at 1875E, 1100N intersected some amphibolite layers embedded in gneiss but there is no data wether these rocks are conductive or not. Figure 3. Presents the ground magnetic map and the anomaly over the profile 1300N. lt seems that there is no mag anomaly in coincidence. Conductor 3 is located close to the contact area of the intrusion. This group of conductors can be explained by "svartskifer or -kalksilikatba- referring the geological map from Bruvann area. Figures summarise the location of conductors detected by the fixed loop ground survey. 3.2.Down hole surve The anomaly at hole is flat. No indication of conductors nearby (within m). Hole is rather flat as well. However there is a weak trend towards the end of the hole which could be related to the same conductor as \,vas picked up at hole Figure 11. Shows the location of the modeled conductor based on the Protem data at hole (Figure 12.) 4 CONCLUSIONS AND RECOMMENDATIONS Surface Protem detected 3 different conductors which are either known or embedded in barren rocks. Conductor number 2. however, is the most - unknown-. Downhole survey detected the conductor which is located below and on the eastern side of the hole This conductor is highly recommended drill tested. to be Risto Pietilä Senior Geophysicist Outokumpu Mining Oy
