Description of work to be conducted and Final Reclamation Procedures: <br /> Sweetwater Mining Corporation plans to re-open re-stabilize and conduct sub-surface <br /> exploration of the existing Adobe Longhorn mine before moving to a plan of operations level <br /> disturbance. The NOI exploration consists of five phases. <br /> Phase One: Safely Re-Opening Portal #1 & #2 <br /> After conducting an onsite reconnaissance of the portal locations on the Adobe Longhorn#1 <br /> claim we found that using hand tools to re-open the portals would put myself and my employee <br /> at risk of falling/sliding scree rock that surrounds the two portals. Our solution is to temporarily <br /> use a bobcat E32 compact excavator with rubber tracks to scrap down the loose rock surrounding <br /> the portal that has fallen into the two-portal locations over the past 100 years. The compact <br /> excavator would be onsite for a maximum of 14 days and then removed from the site for the rest <br /> of the exploration process. <br /> Phase Two: Re-Stabilization of Portal #1 & #2 <br /> The stabilization process of both portals includes installing a wooden framed portal to protect <br /> and stabilize the opening and access point to the sub-surface workings. This will be completed <br /> by using 8" X 8"Douglas fir timbers and cut with battery operated circular saws and hand saws. <br /> The timbers will then be placed in location and secured using both nails and a framing hammer, <br /> lag bolts and a portable battery powered hand drill/driver. A locked metal gate will also be <br /> placed in the timbered entrance to prevent animals & humans from entering the interior of the <br /> mine. <br /> Phase Three: Sub-Surface Stabilization <br /> After completion of the surface stabilization of portal#1 & #2, Sweetwater prospectors will <br /> begin by re-stabilizing the interior of the mine using the same timbering method and tools as <br /> outlined the Phase two, only for the sub-surface workings. In addition to timbering, split set roof <br /> bolts and resin roof bolts will be used if/when necessary. Both types of roof bolts will be driven <br /> using an air powered mining drill/driver. Are ultimate goal with exploring this mine is to use <br /> basic tools that are either battery powered, hand powered, or air powered to minimize the use of <br /> internal combustion tools and eliminate the use of internal combustion equipment wherever <br /> possible to reduce our overall noise, fuel, and engine footprint on location. <br /> Phase Four: Exploration <br /> Sub-surface exploration methods include using hand tools, rock hammers, rock chisels, and pick <br /> axes to chip interior vein samples for offsite lab analysis. Each sample will be bagged in <br /> waterproof sealed bags in the interior of the mine and then placed directly into a hand pushed <br /> mine cart to the entrance of the portal. The mine cart will be unloaded directly into the back of a <br /> pickup truck and hauled offsite. No interior ore samples will touch the ground on the surface or <br /> be exposed the air and rain so there is no opportunity to degrade or contaminant the surface <br /> environment. Traditional mine rail will be laid only in the subsurface workings to facilitate the <br /> movement of the hand powered ore cart. All rail will already be pre-cut before arriving; <br /> completely eliminating the need for a portable demo saw onsite. <br /> Phase Five: Closing Exploration & Interim Reclamation Procedures <br />
