May Day and Idaho Mine Complex 112 (d) Permit Application <br />• Mill Retrofit requires no interim reclamation. <br />• Ore Stockpile Processing <br />The ore stockpiles located at: <br />o May Day No 2 bench (May Day No 2 Operational Area) <br />o Idaho No 1 bench (Idaho Operational Area) <br />o Lamb bench (Lamb Operational Area) <br />and will be processed in the mill, requiring no interim reclamation. <br />• Augmentation Pond Construction <br />The one acre foot augmentation storage pond will be constructed in an area identified on Figure <br />C-4 as outlined in Exhibit 6.5. <br />• Reclamation Activities of Little Deadwood Gulch at May Day No. 2 and Chief Operational Areas <br />will be reclaimed as outlined in Exhibit 6.5. <br />Phase 2 - Milling Optimization <br />• This activity is within the May Day No. 2 Operational Area and does not require interim reclama- <br />tion. Reclamation of this facility will be conducted during final closure. <br />• Proposed tailings storage in stope (i.e., underground) will not require reclamation. <br />Production Phase: May Day No 1. Operational Area <br />• Interim reclamation during this phase will consist of route maintenance of BMPs and weed con- <br />trol. <br />Exploration <br />• Exploration will include 11 boreholes and their associated exploration roads as shown on Figure <br />C-4 (Exhibit Q. <br />• Exploration activities will be limited to drill pads of dimensions 175' x 175' (0.7 acres); 7.7 acres <br />for 11 holes). One hole will be drilled at a time over a period estimated to be approximately 90 <br />days. Each borehole will be abandoned in accordance with State Engineers requirements prior to <br />mobilizing to the next drill location. Re-grading and seeding of each drill pad will commence as <br />soon after abandonment as season and weather conditions permit. Exploration roads will be per- <br />manent. <br />Production Expansion <br />• Based on the results of the exploration phase, the total operational area may be expanded. Interim <br />reclamation activities are not expected during this phase. <br />Milling Completion and Closure <br />May Day Idaho Mine Complex 112(d) Permit Application <br />September 21, 2010 (REVISED Oct. 22, 2010) <br />19
