Buchans River intersects 16.0 metres of 10.30% combined base metals: 6.64% zinc, 3.01% lead, 0.65% copper, & 15.06 g/t silver & 0.11 g/t gold

Buchans River Ltd. (BUV-TSX-V) is pleased to provide results for eight additional holes from its expanded 8,000 metre, drill program on the Lundberg zone located adjacent to the Lucky Strike mine in Buchans, central Newfoundland. Results continue to define a volume of near surface mineralized rock hosting stockwork sulphides which may represent a bulk tonnage resource amenable to open pit mining. Results further indicate higher grade sections exist within a northwest trending corridor that may define a higher grade volume of rock within the larger mineralized zone.
