MacDonald Mines Exploration Ltd. announced that it has received gold and silver assays for 100 sonic boreholes at its Wawa-Holdsworth Project. Most of boreholes were drilled in an exploration target that was defined using geophysical methods, in a previously non-excavated area. Nine sonic boreholes discovered a new zone of Oxide Sands with evidence of significant gold and silver mineralization. Highlights from the sonic drilling program: Discovery of a new Oxide Sand Zone, 250 metres west of the last confirmed Oxide Sands. The strike of the Oxide Sands now totals 1.5 km and remains open to west. Grades of 5.71 g/t gold equivalent ("AuEq") over 3.05 m including 9.31 g/t AuEq over 1.83 m in the newly discovered zone.
