Great Atlantic expands Nashwaak Lake property

Executive Summary

• Great Atlantic Resources Corp. has expanded its 100%-owned Nashwaak Lake tungsten property in western New Brunswick from approximately 222 hectares to approximately 645 hectares through the staking of new mineral claims.
• The expansion includes areas with historical tungsten anomalies, including significant rock samples returning up to 20,300 ppm tungsten and soil samples showing anomalous values.
• The property is located approximately 2.5 kilometres from the Sisson project (Northcliff Resources Ltd.), which hosts a major tungsten-molybdenum deposit with proven and probable reserves.
