Mining Plan <br />Exhibit D <br />will be temporarily stored in the stope until a final disposal plan has been <br />approved by the DRMS. The suitability of the stope for tailings disposal (See <br />Attachment D -6, Attachment D -7, and Attachment D -8) will also be evaluated <br />once access is granted and a registered professional engineer can verify that a dry <br />stope exists. In addition, Wildcat will commit to conducting a humidity cell test <br />(ASTM D- 5744 -7) as outlined in the whole rock analytical work plan <br />(Attachment D -8). See Exhibit U for supporting information. Within 60 days and <br />as approved by DRMS, Wildcat will initiate the ASTM D- 5744 -7 humidity cell <br />test. <br />3. Phase 3 - Production Phase: May Day No 1. Operational Area <br />Following the mill optimization phase, production will begin on the remaining ore <br />stockpiled within the May Day No. 1 Stope (approximately 7,000 tons). Mining will then <br />commence at zones of mineralization in the vicinity of the May Day vein. Current <br />reserve estimates indicate mining will continue for a minimum of 5 years at a rate of 35- <br />100 tons per day, 5 days per week. <br />Blasting activities will be done in accordance with the protocols described in Exhibit 6.5. <br />Power to the mill will be provided by 110 kW diesel powered gensets. Diesel fuel will be <br />stored and handled in accordance with the EPP. (Exhibit U). <br />4. Phase 4 - Production Expansion <br />Based on the results of the underground exploration activities, the total operational area <br />may be expanded. Depending on the design of the expansion, either a Technical <br />Revision or an Amendment will be submitted to the DRMS for review and approval. <br />5. Phase 5 - Milling Completion and Closure <br />At the end of the life of the mine, all remaining ore will be completely milled and tailings <br />disposed of in accordance with the approved Reclamation Plan (Exhibit E) and Division <br />requirements. Closure of the mine will include demolition of non - historic buildings and <br />structures and removal of all salvageable material from the permit area. All non- <br />salvageable material will be buried in place or in the adits and stopes as defined in the <br />Reclamation Plan or removed from the permit area. Reclamation will be conducted as <br />detailed in the Reclamation Plan.
