VANCOUVER, B.C.--(BUSINESS WIRE)--May 17, 2000--Columbia River Resources Inc. (OTCBB:CRVV) is pleased to announce results from Phase II Trenching at the Ayaco Gold Project located on the northern extension of the Yamfo Gold Belt in Ghana, West Africa. These latest results have dilineated the continuation of mineralisation 100m along strike from the previously announced trench. This intersection was encountered on line 130+00N where the weighted average of one metre horizontal channel samples over 8m gave 2.19g/t gold from stations 4717 to 4724. The weighted average over 11m from stations 4717 to 4727 gave 1.88g/t gold. These results are based on 50g Fire Assay determinations which include 4.37 g/t gold over 3 metres. The mineralisation is associated with intensely sheared medium to coarse grained greywacks with quartz veining and pyrite-sericite alteration. The host lithology is similar to that encountered in the mineralized zones at the Yamfo Deposit, on strike and southwest of the Ayaco Project. Repeat analysis of the mioneralised zones, using 600g composite pulps applying the Leachwell method gave 2.63 g/t gold over 8m with a laboratory repeat of 2.55 g/t gold. Over the 11m intersection, the Leachwell analyses gave 1.96g/t gold with a repeat of 2.05g/t gold. These slightly higher values obtained in the Leachwell tests relate to the greater sample weight analyzed and the coarse nature of the gold. IP Analysis and Drilling Recent results of IP profiling along mineralised zone, at 200m line separation, indicated coincidence between a strong chareability and resistivity response. This is linked at surface with the mineralised zone. The geophysical evidence suggests continuity of the mineralised zone for a distance of 2200 metres and persistance to a depth exceeding 200 metres. Final processing of this data is currently being undertaken in Canada. The Phase II Reverse Circulation Drilling programme of 4000 metres is scheduled to commence at the end of next week. The Company will announce drill results as they become available with the first expected to commence within the next 4 weeks. On Behalf of Columbia River Resources Inc.
