May Day Mine and Mill Site, Wildcat Mining Corporation, 110(2) Permit Amendment <br />Exhibit C <br />(d)' Description of Deposit to be Mined (Rule 6.3.3 (1) (c) (d) (e)) <br />Three types of mineralization are distinguished in the permit area: highly disseminated epithermal <br />gold-silver-telluride thin veins [typically less than five (5) feet], limestone replacement deposits <br />and disseminated mineralization in porphyry. Underground mining will occur by conventional <br />cut-and-fill or shrinkage-stope trackless mining along existing veins of the May Day No. I and <br />No.2 portals. <br />As the extent of the deposits is unknown, development and exploration will occur concurrently. <br />(Detailed discussion of the mine and mining physical setting is presented in Attachment C-1' and <br />C- I A-Exploration Program). <br />(e) Mining Operation Components (Rule 6.3.3 (e) (fl (a)) <br />The following components are displayed in Figure E-3 within Exhibit E - Map: <br />Access Roads: Access road to the mine site is directly from County Road 124 as shown in <br />Exhibit E-1 and E-2. The access road as designed (Sukura, 2007) is for vehicles where <br />the gross weight is equal to or less than 15 tons. An access agreement is in place from <br />County Road 124 to the Bridge (owned by Mr. Mike Clement) crossing the La Plata <br />River and an easement granted to Wildcat Mining Corporation from Fairview Land <br />Corporation on a preexisting private road from the bridge to the May Day Mine. <br />Adits: Underground mining will occur at the May Day Level No. 1 (location shown in <br />Figure E-3, Exhibit E - Map). Exploration and development activities will occur at No. 2 <br />portal. No mining is contemplated from the Lamb portal) (Rule 6.3.3(1)(e)). <br />Processing including crushing will operate 7 days a week. Dust production from mining <br />and milling will be controlled using water generated in the work area. Water consumptive <br />use is authorized under the approve water right (Exhibit C- 03). <br />At the May Day Level No. 2 portal the adit will be developed, the portal will be <br />rehabilitated and steel sets are designed and will constructed (see Attachment C-1B) at <br />the entrance, and a bench will be extended directly out from the existing bench. <br />Processing Facilities-May Day No. 1: A mill is contained within a drift with the <br />dimensions of approximately 15 feet wide, 13 feet high and 100 feet long with steel sets <br />placed every 4 feet. The mill will be buried under a geotechnically stable cover of not <br />less than 2 feet to mitigate noise and visual impacts. The milling process is described in <br />Section (m) of this Exhibit and in the attached 43-101 report (Attachment C-1) <br />Ventilation <br />Ventilation has been approved by the Mine and Safety and Health Administration and <br />will be implemented in accordance with MS14A criteria and guidelines.
