3 SUMMARY Geochemical sampling of stream sediments and soils from the TOM claim, 20 units, on a tributary of Tom Creek, 60 km west of Germansen Landing was done by JMT Services Corp. on May 19, Samples have low values in arsenic (1-22 ppm) but weakly to moderately anomalous gold values (to 262 ppb in silt). Gold values probably originate from quartz-rich phyllites and schists of "Cache Creek" group outcropping in the area. A short progrme of mapping and sampling is recamsnended. Barry J. Price, H.Sc., June 15, 1981 FGAC

5 1. a ' NTRODUCTON The Tom claiiu was staked to cover weak rusty-stained rock exposure in a steep walled tr2eutary of Tom Creek. This creek has recorded placer gold productlon of 1624 uunces of gold to LOCATON & ACCESS Figure 1)- The Tom Property is located 40 miles southwest of Germansen Landing, which is reached by 120 miles of summer gravel road from Fort St. James. A four wheel drive road extends from near Germansen Rber to Kwanika Creek and Silver Creek and continues up Kenny 'Creek to Tom Creek. Condition of this road is unknown but should be passahle in dry weather. The property is most easily reached by helicopter from Fort St. James (100 mil, Smithers Capprox. 100 miles), or Genaansen Landing (40 miles). 111 CLAMS (Figure 21 a The Tom Claim was staked by C. Harivel for K. W. Livingstone on April 23, 1980 and recorded on May 23, the first northward flowing tributary of Tan Creek. Tpe 20 unit claim covers V- WORK PROGFV&DE Work on the property was done on play 19, 1981 by B. Price and C. Harivel, geologists. Mobilization was by helicopter fram Smithers for C. Harivel, and from Vancouver, via Germansen Landing by truck for B. Price. A total of 38 samples were taken on two traverses. Geochemical analyses for gold and arsenic were done by Chemex Laboratories Ltd., 212 Brooksbank Avenue, North Vancouver, B.C. Helicopter support was provided by Okanagan Helicopters Ltd., Smithers, B.C. Sample. locations and results are shown in Figure 3 in the map pocket.

7 2. V GEOLOGY Tom Creek, situated in the Vital Plountains, lies within a metamorphosed belt of the Riblion Chert memfier of the Cache Creek GroGp. Exposures along the trihtory of Tom Creek covered by the claim are of grey to black phyllite with numerous quartz partings and lensy veins. Foliation seen along the east creek bank strikes 168O to 188O with steep dip (80 E1_. Some cross cutting quartz-ankerite veins 1 exist, and some float of massive quartz-carbonate-mariposite rock is present in Tom Creek. Quartz-sericite schists are probably present within the creek drainage, judging from the abundance of this material as float: V GEOCHEMSTRY (.Figure 3) Sampling was inhibited by deep snow and high creek levels. A total of 39 soil, silt and rock samples were analyzed for arsenic and gold. a1 ARSENC Values in all types of samples are low, ranging from 1 to 22 ppm. None of the samples are considered anomalous for this element. b) GOLD - Prost soils and silts taken have measureable amounts of gold, ranging from less than 1 ppb to a high of 262 ppb. Samples with over 15 ppb are considered anomalous, and 12 of the 38 samples exceed this value. Quartz-rich phyllites and schists sampled gave 13 and 17 ppb gold. - slightly anomalous. Red soils have significantly higher gold content (e.g. P3521 than those taken over greyish clay till - present on the lower portion of the creek. The highest value occurs in silt- sample H315 from a mall tributary of Tom Creek east of the claim block (262 pfb1 - this value is considered strongly anomalous.

8 V1 CONCLUSONS AND RECOMMENDATONS Based on the results to date, further prospecting and sqpling is warranted on the property and adjacent to it, Source of gold in soils and silts is prohably the quartz-rlch phyllltes and schiks and detailed rock geochemistry will he necessary to verlfy this. Source of the silicfa-carbonate float should b searched for andmore of this material sampled. A short programme of mapping and saapling is recomended; 4 man-days with.2 geologist should be sufficient. Cost of such, a porgramme with.helicopter support, would be approxbately $4, Respectively submitted,
