Summary:In conjunction with bedrock and Quaternary mapping, geochemical sampling of shallow till over the St George granitic batholith of southern New Brunswick delineated most or all of the known occurrences of W, Mo and Cu. Gold was sought in a regional survey of the Grenville Province in eastern Ontario. On the regional scale, the heavy mineral fraction gave the best anomaly definition and contrast but the -250 mesh fraction was found to be the most cost effective for defining exploration targets. For detailed surveys, humus was found to be highly cost effective. [T.F.]
