StructureUnique Continuity Of Gold-Bearing Horizons Over Extended Area, Though Well Marked By Folding, Faulting And (Locally) Erosion And Redeposition Of Overlying Conformable Sediments., Dips Vary From Gentle To Nearly Vertical In Mine Area. Folding And Faulting From Moderate To Severe. Overlying Lavas And Dolomites Are Thin To Massive. Both Minable Reefs Outcrop On Mine Property In Upthrow Fault Blocks, But Bulk Of Ore Occurs At Depths In Excess Of 200 Meters.
