i <br /> EXHIBIT D RECEIVED <br /> 6.4.4 EXHIBIT D — Mining Plan MAR 2 0 2025 <br /> DIVISION OF REDLAMATId b a <br /> MINING AND SAFTIEY <br /> (A) Description of The Method(s) of Mining to Be Employed <br /> The West Side Placer will employ placer mining methods.This includes the digging,moving ore,processing ore,returning <br /> ore to the active mining block and reclaiming. <br /> Mining activities will take place in five-acre blocks,with no more than three blocks disturbed at one time.Typically,one <br /> block is actively being mined,one is being stripped in preparation for mining,and one is in reclamation.Including the six- <br /> acre footprint for the screening plant,within the already disturbed 9.9 acres from the current 110 permit.The maximum <br /> total of 29.9 acres will be disturbed at any given time. <br /> The following methods will sequentially employ when mining;refer to Table D.(A).1. <br /> (1) Prepping The Mining Block <br /> 1. Documentation <br /> A gps survey will be run on each mining block,marking out corner configurations for the block to be mined. <br /> Coordinates will be recorded and documented.Site photography will be used to document pre-mining state of each <br /> block. <br /> 1 <br /> 2. Physical Prep of Mining Block <br /> A bulldozer will be used for the systematic stripping of topsoil across each 5-acre mining block.The bulldozer is tasked <br /> with removing a layer of topsoil,ranging from 8 to 16 inches in depth.Once removed,the topsoil will be carefully <br /> stockpiled along the perimeter of the mining block.This strategic placement aids in preserving the topsoil for future <br /> reclamation purposes.The topsoil removal process within a 24-hour period for each mining block(Three eight-hour <br /> shifts). <br /> (2) Mining of the Ore Body <br /> The ore body is situated directly beneath the topsoil layer.The excavator or scraper will systematically works its way <br /> downward,gradually creating a vertical wall along the interface of the ore body.This methodical approach ensures <br /> controlled excavation and stability of the mine walls.The excavation will advance methodically towards the far end of <br /> the mining block.A maximum of 20 acres(4 mining blocks)of the mining will be exposed for stripping,excavation and <br /> reclamation at any given time.Each block will be mined in approximately a month or less. <br /> 1. Moving of Ore to Screening Plant <br /> Haul trucks or scrapers will be used to move ore from the active mining block to the screening plant.County roads <br /> and temporary haul roads will be used to move ore from the active mining block to screening plant. <br /> 2. Processing Ore at Screening Plant <br /> The primary function of the screening plant is to efficiently sort, and process excavated material,generating a 4 mesh <br /> 13 <br /> HARD ROCK/METAL MINING REGULAR(112)APPLICATION AuPt Industries LLC I PO Box 1424-Edwards,Colorado 81632 1970 306 1784 <br />
