3 SUMMARY Tiara Resources Corporation holds the Blue claims in the Cariboo Mining ~ivision of Central British Columbia. They are situated 130 kilometres northwest of Williams Lake, near the headwaters of Blue Lead Creek. Access is by helicopter. The property was staked in 1982 to cover an antimony anomaly resulting from a regional stream sediment survey carried out by the government. Also reported in the claim area is an occurrence of galena in quartz-veined limestone. Two days were spent prospecting, mapping and sampling in March Snow conditions were hazardous, providing poor access to outcrops. The property is underlain by sericitic and graphitic phyllite, quartzite and muscovite schist. Extensive quartz veining is evident by the abundance of quartz in float. The quartzite locally contains abundant pyrite. CONCLUSION Snow conditions at the time of the examination prevented any evaluation of the Blue claims. The antimony anomalies reported in the 1980 government geochemical release were not confirmed. However, the lack of -80 material in the sediment samples collected may have affected results.

4 A sample of pyritic and quartz veined quartzite was found to carry highly anomalous gold values (900 ppb). The abundant quartz vein material observed in float indicate that ma'pping and geochemical sampling should be continued when snow conditions permit. RECOMMENDATION A three phase exploration program is recommended to examine the known showings and to evaluate the potential for precious metal and tungsten deposits. Phase I is designed to carry out a preliminary prospecting, sampling and geological mapping. Phase 11, contingent on results of Phase I, consists of follow-up geological, geochemical and geophysical surveys, and Phase 111, if results of Phases I and I1 warrant, consists of diamond drilling. The estimated costs of each are: $17,000., $27,000., and $50,000. respectively.

6 INTRODUCTION The Blue claims were staked in 1982 to cover a 32 parts per million antkmony geochemical anomaly that was obtained from a regeional geochemical reconnaissance program carried out in 1980 by the Provincial and Federal governments (Open File 776, RGS-5) for the Quesnel Lakes area. A drainage 8 kilometres southwest of the claims yielded a 13 parts per million antimony anomaly. The claim area was reported to have been previously explored in 1975 and known as the Blue Lead property. Galena was reported to occur in quartz veins in limestone (B.C. Ministry of Mines Assessment Report 5537 and 1975 Annual Report p. E 125). The property was staked originally because of this reported occurrence and because of the potential association of gold with antimony (antimony is a common associate of gold and hence an important indicator element). Prospecting, mapping and sampling were carried out by D. Fleming and R. Kidlark on March 17 and 18, Deep snow and avalanche conditions prevailed, hindering access and providing few accessible outcrops and stream sediment sample locations.

8 LOCATION, ACCESS, PHYSIOGRAPHY The claims are situated 135 kilometres northeast of Williams Lake, B.C. (figures 1 and 2). and 82kilometres east of Likely, B.C. The claims cover an east flowing tri- butary of Blue Lead Creek, which in turn flows'into the east end of Quesnel Lake. Topography in the area ranges from moderately steep on the valley slopes to gentle on several flat benches. Elevations range from 1300 to 2300 metres. Access is by helicopter, based in Williams Lake or Quesnel. CLAIM DATA The property consists of 42 claim units (figure 3) as follows : Claim Name No. of Units Record No. Expiry Date Blue March 22, 1984 Blue March 22, 1984 Blue March 22, 1984 The claims are registered in the name of Douglas MacQuarrie but have been transferred to Tiara Resources Corporation.

11 (Windermere) Kaza Group and Isaac formation. Rock types include greywache, phyllite, schist and limestone. Lower Paleozoic shale and carbonate miogeosynclinal rocks outcrop north of the north arm of Quesnel Lake. Two prominent northeast trending faults cut through the property. Jurassic and Cretaceous intrusive rocks outcrop 12 kilometres to the southeast. Property Geology The Blue 1 and 2 claims, as indicated by stream bed float, are underlain dominantly by sericitic and graphitic phyllite with minor quartzite. Quartzite in outcrop was highly pyritic and quartz veins cutting the quartzite, carried minor disseminated pyrite. Streams sampled farther southwest along Blue Lead Creek, carried dominantly quartz-muscovite schist in float, with minor quartzite and phyllite. Carbonate stratigraphy was spotted from the air, southeast of Blue Lead Creek. Abundant quartz veining is evident on the claim group by angular quartz float in the stream beds. GEOCHEMISTRY Stream sediment samples were collected and where the snow cover permitted access to the creek beds. As a result, insufficient -80 mesh silt material was obtained for standard geochemical analysis.

12 The samples were therefore screened to -40 mesh and this fraction analyzed. Samples were analyzed for Mo, Cu, Ni, Co, Mn, Fe, Ag, Zn, Pb, Sb, Au and W. Sample sites are plotted on figure for and presented in Appendix I. Above background values were obtained for nickel ( >40 ppm) and tungsten ( >I0 ppm). A single grab sample from an outcrop of quartz-veined and pyritic quartzite (83 BFT 20) returned a significant gold geochemical anomaly (900 ppb Au).
