Mining Plan <br />Exhibit D <br />F. Ore Stockpile Processing <br />Several historic stockpiles have been identified as having ore concentrations that are <br />suitable for milling and or for offsite processing. These are located at: <br />• May Day No. 2 bench; <br />• Idaho No. 1 bench; and <br />• Lamb bench. <br />The ore stockpiles (Figure D -5) will be re- located to the May Day No. 1 adit, using pre- <br />existing roads or hauled offsite for processing. <br />G. Augmentation Pond Construction <br />If an augmentation pond is required pursuant to Colorado State Engineer (SEO) <br />requirements, the augmentation pond will be located within the designated Idaho <br />Affected Area (Figure C -4). The augmentation pond construction work plan is presented <br />in Attachment D -6. The pond will be a non jurisdictional structure as defined by the <br />Colorado Division of Water Resources (DWR) regulations, and will be designed by a <br />Colorado Registered Professional engineer in accordance with DWR regulations and <br />maintained in accordance with SEO water right requirements. <br />H Reclamation Activities <br />Channel reclamation activities will be undertaken to remove soil and rock debris located <br />in Little Deadwood Gulch at both the May Day No. 2 and Chief Portal Operational Areas <br />per the approved work plans (See Attachment D -3 and Attachment D -4, respectively). <br />Areas disturbed when stockpiles are consolidated will be graded, contoured, stabilized, <br />and seeded in accordance with the Reclamation Plan. (Exhibit E). <br />2. Phase 2 - Milling Optimization <br />Following the mill retrofit, there will be a period of milling optimization using 7,000 tons <br />of the material that is located within the May Day No. 1 underground workings and ore <br />stored on the surface. Optimization is estimated to take at least 90 days following mill <br />commissioning. A final mill process description will be provided to DRMS within 30 <br />days of the completion of the optimization phase. <br />Wildcat Mining Corporation <br />May Day Idaho Mine Complex — 112d Permit Application <br />Revised August, 2011 <br />Exhibit D — Rule 6.4.4 <br />Page 5 of 10 <br />
