AVERAGE WIDTH OF THE ORE ZONE (171 METERS) IS MEASURED ALONG THE DIP PLANE OF THE ORE BODY. THE MINIMUM DEPTH TO THE MINERALIZED ZONE IS THE FLOOR OF THE EXISTING PIT (A DEPTH OF 30 METERS FROM THE ORIGINAL LAND SURFACE). TOTAL ESTIMATED DEPTH TO THE ORE BODY IS ESTIMATED TO BE 191 METERS FROM THE SURFACE. GENERAL STRIKE AND DIP OF THE ORE ZONE IS WEST-NORTHWEST DIPPING 50 DEGREES SOUTH. |
