Meadowbank Gold Mineralization

• The deposits show seven styles of sulfide mineralization that are grouped according to their relationship to the major deformation phases.

• Pre-D2 includes four styles of gold mineralization.

• 1) Early pyrrhotite replacement in oxide facies BIF along S1

• 2) Early pyrite replacement in oxide facies BIF along S1

• 3) Early, deformed, pyrrhotite bearing polymetallic S1 quartz veins in BIF and IV

• 4) Early, deformed, pyrite-rich, vuggy S1 quartz veins in BIF and IV
