Ottawa, Ontario (March 1, 2011) - Northern Shield Resources Inc. ("Northern Shield") [TSX-V: NRN] and Discovery Harbour Resource Corp. (“Discovery Harbour”) are pleased to announce that drilling has commenced on Northern Shield’s Wabassi Property in northern Ontario. Six drill-holes, totaling 1500 meters, are currently planned. Drilling will test VTEM anomalies “E and “C” and two larger ground EM anomalies within the A1 Zone where copper-(nickel) mineralization was discovered by Northern Shield and Discovery Harbour during last year’s drill program.

A recently completed ground EM survey completed over Anomaly E confirmed the presence of a 500+ meter long target that has considerable depth extent and strong conductivity.
