conc_proc: Primary Sulfide Mineralization Extends To The Present Surface And Oxidation Is Limited To The Upper 15 Meters Of Fault And Fracture Zones. No Secondary Enrichment Has Taken Place Since Pleistocene Glaciation.
ore_ctrl: Fine Grained Bedded Tuffs Are The Most Favorable Host Rock Because Of Their Propensity For Brittle Fracture. The Lost Horse Intrusive Is Considered To Have Been More Important In Localizing The Orebodies Than The Copper Mountain Stock.
