1.0 SUMMARY
The Kot 1-4 claims were staked to encompass a base metal (Pb,Zn) anomaly identified by a government sponsored geochemical survey.
The 1988 Kot program consisted of (1) grid location and construction; (2) ground geophysical (VLF and magnetometer) and (3) soil geochemical surveys.
The geophysical survey revealed two prominent north trending conductors. The soil geochemical survey showed only a few weak base metal anomalies. There is no apparent correlation between either of the geophysical conductors and the geochemical data.
2.0 INTRODUCTION
2.1 Location and Access
The Kot 1-4 claims are located approximately 120 km north northeast of the community of Smithers in Central British Columbia (Figure 1). The claims are located at the south end of the Nilkitkwa Range (latitude 55O 4 8 ' N; longitude 126O 50' W) in the southwestern portion of the Kotsine River Map sheet (N.T.S. 93M/15). The property is located midway between Kotsine Mountain and the Nilkitkwa River (Figure 2).
The Kot claims are most readily accessed by helicopter. The nearest road is situated near Boucher Creek on the east side of the Nilkitkwa River, approximately 30 km to the southeast. The Kot property is located roughly 22 km southwest of the British Columbia Railway track at Driftwood.
2.2 Propertv Status
The Kot 1-4 claims, owned by Placer Dome Inc. (P.O. Box 49330, Bentall Postal Station, 1600-1055 Dunsmuir St., Vancouver, B.C., V7X lPl), were staked in June and registered in July of 1985 (Table 1). They consist of four blocks each containing 20 mineral claims. The four blocks are centered about a common corner post located at UTM Northing 6186350 and Easting 635800 (Figure 2).

3.0 REGIONAL GEOLOGICAL SETTING
Figure 3, from Richards (1980), shows that the Kot property covers part of a large fault-bounded block of Jurassic age Volcanic and sedimentary strata which crops out in the upland ranges between the Nilkitkwa and Driftwood Rivers. The geology of the area is discussed in some detail by Tipper and Richards (1976). Tipper and Richards suggests that the Jurassic strata exposed in the Nilkitkwa and Driftwood Ranges reflects the development of a marine trough within the Hazelton volcanic arc. The package consists of four principal stratigraphic units. These are: (1) Unit lJTa (Figure 3), a basal unit of subaerial volcanic strata (Telkwa Formation: Bear Lake Facies): (2) Unit lJTm (Figure 3), an equivalent marine package: (Telkwa Formation: Kotsine Facies); (3) Units 1JN and lmJN (Figure 3), a mixed sedimentary and volcanic package (Nilkitkwa Formation) and (4) Unit MJS (Figure 3) an overlying package of fine classic sediment (Smithers Formation: Bait Member).
The Kot claims cover an area of anomalous stream sediment geochemistry underlain by volcanic and sedimentary strata belonging to the Kotsine Facies of the Telkwa Formation and to the overlying Nilkitkwa Formationb. The package is intruded by a sill or dyke of Early Jurassic diabase (Unit EJdb; Figure 3) which is correlated with a marine extrusive phase (Unit 1JA; Ankwell Member) of the Nilkitkwa Formation.
4.0 WORK PERFORMED
4.1 Introduction
The geochemical anomaly tested by the 1988 program is situated in a flat lying swampy area in claim block Kot 4. It was in this area that a grid was established (Figure 4), and the work was performed by a four-man crew.
The location of the property is such that it was accessed by helicopter from Smithers on a daily basis.

The grid was constructed using hip chains, compass and flagging. The work was contracted out. The geophysical and soil sampling surveys were performed by Placer Dome personnel.
4.2 Geoloav and Mineralization
Exposure on the area of interest is very poor. It is limited to only a couple of outcrops. In the area of the grid, the geology consists of north striking steeply dipping beds of shale, crystal tuff and laminated sandstone, all of the Telkwa Formation. Overlying the Telkwa Formation is the Nilkitkwa Formation, a mixed sedimentary and volcanic unit. A diabase sill within the Nilkitkwa Formation, located along the northerly trending ridge straddling the Kot 1 and Kot 2 claim line, forms the western boundary of favourable geology. (Figure 3)
Table 2 below documents the four rock samples taken during the 1988 program. The samples were sent to the Placer Dome Inc. laboratory in Vancouver for analysis. Results are listed in Appendix 1.
TABLE 2
SUMMARY ROCK DESCRIPTIOK
m!L& DescriDtion
26053 Grab sample from outcrop in creek bed. Rusty volcanic agglomerate. Calcite and quartz veining and flooding with up to 0.5% disseminated pyrite. No sulphides associated with the veins.
26054 Grab sample consisting of angular shale fragments uprooted by a fallen tree (not outcrop). Very sparse euhedral pyrite disseminations and calcite micro-veins.
26055 Grab sample from probable outcrop of rusty red crystal tuff. Outcrop forms a north, north- east trending ridge. Tuff is pyritic (0.1%) with some carbonate enrichment.
26056 Grab sample from possible outcrop. Small ridge at eastern edge of swamp. Black shale fragments with 5-10% quartz and calcite veining. Up to 0.5% disseminated pyrite and possibly very fine, dark sphalerite.

Of the four rock samples submitted for analysis, none gave a significant response other than a moderate zinc anomaly. Sample number 26056, taken from a northerly trending ridge, contained 0.9% Zn 272 ppm Cu and 54 ppm Pb. This specimen contained quartz and calcite fracture fillings with only a minor amount of visible sulphides along fracture walls. Samples of red crystal tuff and fine laminated sediment are fractured, and contain quartz infilling and other vein signatures but were devoid of base or precious metal mineralization.
4.3 Soil Geochemistry
The first phase of the 1988 program involved the location of a grid that was used for the geophysical survey and for locating soil samples. The grid was centered over reconnaissance soil sample #330 taken during the 1985 program. (April 1986 Assessment Report KOT 1-4 Claims)
The grid consisted of a one kilometer, cut, baseline running north-south and tied into the creek located approximately 500 meters to the east. Crosslines were constructed at 50 meter intervals either side of the baseline. The crosslines were established by compass and hip chain and stations were marked with flagging every 20 meters.
In 1988, a total of 42 B horizon soil .samples were collected at 40 m intervals, along lines 10+00N, 12+00N, 14+00N and 16+00N (Figure 5).
The samples were shipped to the Placer Dome laboratory in Vancouver where the -80 mesh fraction was analyzed for Au, Ag, Pb, Zn, Cu and Ba. The analytical data are listed in Appendix 11. Figures 6-10 show the distribution of Cu, Pb, Zn, Au, Ag and Ba in the soil.
The data show that there are some weak base metal (Pb,Zn) anomalies. There are no significant precious metal anomalies. The highest zinc value (1280 ppm) occurred at station 10+00N 13+00E, in the southeast corner of the grid. The lead values obtained showed few significant anomalies (high value of 77 ppm at 16+00N 12+40E). Values ranged fairly consistently between 10 and 15 ppm.
The geochemical data show no positive correlation with the north trending VLF conductors identified in the area of the survey.

4.4 GeoDhvsics
Survev Parameters
The geophysical surveys on the Kot claims were carried out during June 27-30, 1988. A total of 8.4 kilometers of line were surveyed. VLF readings were taken at 20m stations and magnetic readings at 10m stations. The station at Jim Creek (near Seattle, Washington) was used for the VLF survey.
EaUiDment Used
The magnetometer survey was conducted using a Geometrics G-856A portable proton magnetometer (memory- mag). The magnetometer data was tied to a base station value established on the grid. The data from the magnetometer was dumped out to floppy disk on a Kaypro I portable computer and eventually transferred to a Sun Microsystem work station for final plotting.
The VLF-EM survey employed a Geonics EM-16 which used the following transmitting station:
Jim Creek NLK 24.8 )dIz
VLF readings were also entered onto floppy disk in a Kaypro I computer and later transferred to a Sun Microsystem work station for final plotting.
Plottins of Results
The magnetometer survey results were plotted as plan maps of stacked profiles and posted data at a scale of 1: 2500 (Figure 12) An additional map was prepared after a five point filter had been applied to the magnetic data (Figure 13).
The VLF survey results were plotted as a plan map of the In-phase, Quadrature and Fraser Filter data at a scale of 1:2500 (Plan maps of posted data for in-phase and quadrature have also been plotted). The Fraser Filter data was calculated as per the method put forth by D.C. Fraser (1969, Contouring of VLF-EM data, Geophysics v. 34 p 958-967). See maps in the folder at the back of report (Figures 11, 14, 15).
6
Results of Geouhvsical Survevs
Two prominent VLF conductors were detected in the VLF survey. Several apparent contacts were outlined on the stacked profile magnetic maps.
5.0 CONCLUSIONS
The 1987 Xot exploration program has revealed two prominent VLF conductors in the southeast corner of the grid and has not exposed any significant base or precious metal geochemistry.
The VLF conductors are still open to the north and this area is still geochemically untested.
