Mineral Deposit Model
Comment (Reserve-Resource): SCOTT BERRY HAS STATED THAT THE DUMPS ARE 70% RECOVERABLE. THIS MATERIAL WILL BE LOADED DIRECTLY INTO THE PRIMARY CRUSHER BY THE MILL FRONT-END LOADER.
Comment (Reserve-Resource): A PENNINGTON CO. PEGMATITE PROPOSED OPERATION WILL REPROCESS DUMPS LEFT BY PAST PRODUCERS AND GLORY HOLE MINE RESOURCES IN RECOVERABLE MT
Comment (Geology): THE GEOMETRY SET DIMENSIONS ARE A COMPOSITE FROM THE ADDING OF THE FIVE PEGMATITE ORE BODIES TOGETHER. THE DIP IS VARIABLE BUT IN GENERAL IS GREATER THAN 55 DEGREE IN AN EAST SOUTH-EAST DIRECTION.
Comment (Ownership): U.S. MINING IS THE ACTUAL PROPERTY OWNER FOR THE INGERSOLL MINE: A 10% LEASE/PURCHASE OPTION IS HELD BY THE INGERSOLL MINING COMPANY.
