EXHIBIT D MINING PLAN This Exhibit, through reference to the sections itemized below, describes the methods that will be used for mining ore and overburden materials and associated beneficiation of the ore for this Amendment 11. Surface mining methods at the Cresson Project will remain essentially the same as currently approved. Amendment 11 adds underground development and mining methods, extends the final crest elevation of the East Cresson Overburden Storage Area (“ECOSA”), modifies the mining and backfilling sequence of the Globe Hill/Schist Island Mining areas, and modifies the final stacking plan for the Arequa Gulch Valley Leach Facility (“VLF”). The sections referenced below provide a description of method(s) of mining to be employed; discussion of earthmoving; water diversions and impoundments; the size of area(s) to be worked; and an approximate timetable for the operations. Also referenced below are the sections that describe the nature, depth, and thickness of the ore bodies to be mined; the primary and secondary commodities to be mined; and the intended use. Gold and silver continue to be the primary commodities mined at the site. The sections of the Project Description that describe the mining and processing for both surface and underground operations also are referenced below. The information to address this Exhibit is contained in the Project Description in Sections 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, and 12.0 of Volume I of this application. The contents of each section are described below. Section 5.0 Mining and Operations Management Plan (Surface and Underground) Section 6.0 High Grade Mill Facilities Section 7.0 Valley Leach Facilities Section 8.0 Precious Metals Recovery Facility Section 9.0 Support Facilities Section 10.0 Surface Water Management Section 11.0 Monitoring Section 12.0 Reclamation and Closure Appendices 1 through 14 contain detailed information relevant to the Mining Plan.
