Ore controlNortherly- And Northwesterly-Trending Faults And Their Intersections Host Au Mineralization. These Faults Can Host Au Values Exceeding 0.25 Opt Au Over Narrow Widths, Suggesting They Are The Main Conduits For Au-Bearing Hydrothermal Fluids. Dikes Occupying The Faults Host Small Volumes Of High Grade Ore. Economic Au Mineralization Rarely Migrated More Than A Few Feet From The Faults.
