3 r- SUMMARY NTRODUCTON This report sumnarizes the results of a diamond drilling programme completed on the Red-Chris Property during June Work was conducted by Texasgulf nc. on behalf of Texasgulf Canada Ltd., Great Plains Development Company of Canada Ltd. and Silver Standard Mines Ltd. A total of metres of diamond drilling, in five holes, was completed during the 1978 program. Drilling was contracted to D.W. Coates Enterprises Ltd. of Richmond, B.C. who employed a diesel-powered Boyles BBS-1 wi re1 ine rig, recovering BQ core. PROPERTY LOCATON, ACCESS AND TERRAN The Red-Chris property, comprising 241 mineral claims, fractions and MGS units, is located northwest of Kluea Lake, some 20 km southeast of skut Village at approximately latitude 57"45'N, longitude 129'45'W (see Location Map: Fig. 1 and Property Claim Map, Fig. 2). Access is by helicopter from the Stewart-Cassiar Highway at Tatogga Lake or Eddontenajon, or by bulldozer trail leading southward from the 6.C. Railway access road west of Ealue Lake. vehicles only. HSTORCAL OUTLNE This trail is passable for tracked Mineral showings have been known for many years in the area lying between Kluea and Ealue Lakes. The present phase of exploration activity on these prospects began in 1969, when Great Plains Development Company of Canada Ltd. located the Chris and Money claims. Programmes of geological mapping, geochemical soil sampling, magnetic and induced polarization surveys, followed by trenching and diamond drilling, totalling 1230 metres in ten holes, were completed by Great Plains during the period The Red and Sus claims were located by Silver Standard Mines Ltd. in Geological, geochemical and geophysical surveys, followed by bulldozer trench'ing were completed in 1971.

6 Ecstall Mining Ltd., now Texasgulf Canada Ltd., became interested in Silver Standard's property in An option agreement was negotiated and a percussion drilling programm, totalling approxiamtely 900 metres in 14 holes, was completed. nitial results were encouraging and a mre thorough exploration program was proposed. n 1974, an agreemnt was negotiated with Great Plains whereby the Chris and Money claims were pooled with the Silver Standard and Ecstall holdings. During the period further geological, geochemical and geophysical surveys were undertaken and a total of 67 diamond drill holes and 30 percussion drill holes were completed, aggregating 12,265 metres and 2,280 metres respectively. As a result of this work, two zones of significant copper-gold mineralization were outlined; the broad, low-grade Main Zone and the much smaller, but higher grade East Zone. Comnercial production from these zones was not feasible under economic conditions prevailing in 1976, but it was apparent that the potential of the property would be enhanced if the tonnage of higher grade material, accessible to open pit mining, could be increased. To this end, a programme of bedrock surface geochemical sampling was completed over the Main Zone in 1977 in an attempt to define higher grade zones at the sub-outcrop. Anomalies defined by this work were tested by the 1978 drilling program forming the subject of this report DAMOND DRLLNG PROGRAMME Results of the 1978 diamond drilling programme were disappointing. high grade mineralization, comparable in tenor to the East Zone, was intersected. Geological and assay data are summarized in the drill logs included as Appendix A of this report. Drill hole collar locations relative to claim boundaries and previous No

8 - 3- drill sites are shown on the Drill Hole Location Plan (Fig. 3) following page 2. t should be noted that core was logged in mperial units, to conform with data obtained prior to metrification. All core, from this and previous drilling programmes, is stored at the camp site, on the property. CONCLUSONS The new data obtained in 1978 do not alter earlier geological interpretations in any significant way, however they do indicate that higher grade mineralization intersected at depth in earlier drilling on the Main Zone, cannot be projected upwards to the sub-outcrop. The estimated tonnage of mineralized material available to open pit mining on the Main Zone, has been reduced by approximately 4%, the average grade remains unchanged and the stripping ratio has become slightly less favorable. The Red-Chris Property remains a significant copper resource, but cannot be considered an ore reserve under prevailing economic conditions. J.M. Newell, P.Eng.
