The overall setting for the project is shown in Figure 2.
BLOCK 18 – NATURE OF ACTIVITY The Rosemont Project is a copper mining project. The Project will produce more than 230 million (M) lbs of copper per year (roughly 10% of annual US production) for 20 years. Average annual production of molybdenum and silver will be 5 M lbs and 3.5 M oz, respectively. Past and recent exploration activities have confirmed or identified the availability of approximately 600 million tons (MT) of ore. This schedule estimates a mill through-put of approximately 75,000 tons per day, which translates into an annual mill through-put of approximately 27 MT per year.
Mining of the ore will be through conventional open-pit mining techniques. Waste rock will be blasted and transported by haul truck to the waste rock storage area. Ore will be blasted and either transported by haul truck to the leach pad, or crushed and loaded onto a conveyor for transport to the mill. Ore will be processed either by conventional sulfide milling or by leaching. Tailings will be stored using a dry stack tailings technique minimizing airborne releases and water seepage. The placement of waste rock will be initiated with perimeter buttresses and will be placed in the dry-stack tailings storage areas to provide structural and erosional stability of the tailings pile.
The copper concentrates from the milling operations will be shipped off-site to a smelter. Leach ore (oxide material) will be placed on the leach pad. Solutions from the pad will be collected in a solution pond and then processed through the SX/EW plant. Copper cathodes generated from the SX/EW plant will be transported off site for further processing.
The proposed project will involve the construction and operation of various mine features, associated structures, and anticipated infrastructure necessary to support these facilities. These constructed features include: the mine pit, waste rock storage areas, heap leach area, dry-stack tailings facility, ancillary facilities and structures, mine haul roads, access roads, and off-site water and power transmission lines. The nature of the activities associated with each of these mine features, with regards to this permit application, is described below.
Mine Pit The design of the open pit and internal mining phases incorporates geotechnical recommendations for safe slope angles, internal ramp development for access to all working areas, and pit wall smoothing to enhance stability and operator safety. Pit slope angles between ramps will vary according to rock strength, lithology and structural controls, but are expected to range from 28° to 48° between ramps. Where possible, catch benches will be spaced on 100-ft vertical intervals to maximize the effective widths for containing scree. At the rim, the ultimate open pit will be about 6,500 ft across north to south, 6,000 ft across east to west (totaling about 950 ac in area), and will be about 1,800 to 2,900 ft deep. The pit bottom elevation is projected at 3,150 ft above mean sea level (amsl).

Seven conceptual mining phases, or pushbacks, were developed for the feasibility study of the Rosemont Project and used to generate a mine production schedule. Each phase will develop about two to four years of sulfide ore reserves for the 20-year production schedule. The first phase, or starter pit, will be located toward the southwest corner of the ultimate pit, leaving about a 300-ft-wide subsequent pushback in Phase 5 that will extend to the final limits along the west side. Peak material handling rates will occur in Years 1 and 2 falling off slightly starting in Year 3. A sulfide ore stockpile will be constructed near the primary crusher, mostly within the ultimate pit limits, to facilitate subsequent recovery in Year 1 of mill operations.
The pit bottom will reach 5,050 ft amsl elevation in Phase 1. Phase 2 expands the starter pit to the east and north. Waste stripping in Phase 2 will advance to the 5,250 ft amsl bench. Phase 3 further extends the pit to the east, and Phase 4 expands the open pit to the north and east. Nearly all of the oxide ore reserves will be placed onto the leach pads by the end of Year 6. Phase 5 will enlarge the pit on the west and southwest sides to their ultimate limits. The pit bottom will be at the 4,250 ft amsl bench, and the upper benches on the west side of the pit will reach their ultimate limits as Phase 5 stripping commences from 6,100 ft amsl down through the 5,850 ft amsl elevation. Phases 6 and 7 progressively expand the pit to the east and southeast, following the orebody down its easterly slope.
Waste Rock The waste rock storage area, approximately 1,460 acres in size, will be constructed south of the tailings facility. It is designed to accommodate approximately 750 million tons of material, with an additional 540 million tons of waste rock dedicated to construction of the perimeter buttress and other facilities. The waste rock storage area will receive pit-run waste rock consisting largely of limestone and skarn rock types, with some andesite, quartz monzonite porphyry, and arkose. The presence of substantial quantities of limestone and skarn will provide a large buffering capacity within the waste-rock storage areas to minimize the generation of acid rock drainage (ARD).
Site preparation of the waste rock storage areas will involve grading the existing topsoil in preparation of construction of the perimeter buttress. Graded material, in addition to waste rock, will be used onsite. Flow-through drains will be constructed within the major drainages to facilitate stormwater flow through the waste rock storage area.
The placement of waste rock on the south and east sides of the waste rock facility will be initiated with perimeter buttresses designed to minimize the visual effects of the project for travelers on State Route 83 (SR 83) and for viewers in the surrounding area. The outside face of the buttresses will be revegetated and reclaimed as soon as practicable after they are completed. Waste rock in the remaining portions of each phase will then be deposited west and/or north of (behind) these buttresses. Waste rock will also be placed in the dry-stack tailings storage areas to provide structural and erosional stability.
Concurrent with the starter buttress construction, waste rock will be deposited in lifts internal to the waste rock storage area in the upper Barrel Canyon and Trail Canyon drainages. This concurrent development is necessary to minimize congestion and improve safety and equipment productivity in the buttress areas. The ultimate crest elevations of the waste rock storage areas at the end of mining operations will be about 5,600 ft amsl for the Barrel Canyon drainage and 5,300 ft amsl for the Trail Canyon drainage.
Heap Leach Oxide ore will be transported by haul trucks from the open pit to lined leach pads. The oxide ore will not be crushed, but will be dumped in 30-ft-high lifts atop the lined pads for subsequent leaching. Crawler dozers will be used to spread the oxide ore and cross rip the material to a depth of 5 to 6 ft to promote the infiltration of barren leach solution. Oxide ore will be leached with weak acidic solution, and the leach solution will be processed using solvent extraction-electrowinning (SX-EW) technology to produce high purity copper cathode plates. Oxide ore mining and placement on the leach pads will be concentrated in the early years of operation. About 85% of the oxide ore will be placed onto the leach pad by the end of Year 5 and by Year 10 the pad should be drained and closed. As the area of the leach dump will be
Page 2 of 10 Rosemont Copper Project, SPL-2008-00816-MB Section 404 Permit Application overlain with waste rock, the acreage dimensions of the area are included within the area calculations for waste rock storage. Site preparation of the waste rock storage areas will involve grading the existing topsoil in preparation of initial site construction. Impacts to potential waters of the U.S. will occur during initial site preparation. Captured storm flows will be incorporated into the process flows.
A stormwater pond will be installed to collect any excess water that may be generated during a large precipitation event. The Pregnant Leach Solution (PLS) pond, a double-lined collection pond containing the copper-bearing leach solution, will be designed to overflow to the stormwater pond. Water that may accumulate in the stormwater pond will be periodically transferred by pumping to the raffinate solution pond.
Tailings Dry-Stack Facility The Rosemont dry-stack tailings facility will receive dry tailings from the sulfide ore processing plant. This material will be stacked behind large buttresses constructed from pit-run waste rock. Consequently, this waste rock storage area will be active from late preproduction throughout the life of the mine. The dry- stack tailings facility will ultimately measure approximately 987 acres in area. The general design concept is to construct uniform lifts of dry tailings that are buttressed by the waste rock containment berms.
Advantages of the dry stack tailings stack method over conventional tailings disposal are:
• eliminates the need for an engineered embankment and seepage containment system • maximizes water conservation and minimizes water makeup requirements • can result in a more compact site • allows opportunities for concurrent reclamation and dust control
Site preparation for the tailings will include grading and, where appropriate, construction of flow-through drain systems consisting of coarse rock material. An initial buttress will be constructed with waste rock to accommodate approximately one year of tailings storage. Concurrent tailings and waste rock placement will occur throughout the life of the tailings facility. Waste rock will be advanced ahead of the tailings level in successive lifts. The waste rock buttresses will have top widths of 150 ft to accommodate two-way haul traffic and outer slopes of about 3H:1V with benches to achieve an overall slope of approximately 3.5H:1V. This configuration will allow visual screening of the tailings placement activities from SR 83 and concurrent reclamation of the lower perimeter buttress slopes.
Dry tailings will be delivered by conveyor from the filter plant down to the tailings facility. Tailings will be placed with a radial stacker and a dozer will be used to spread the dry tailings and provide sufficient compaction for the conveyor and stacker as necessary. When the primary conveyor is inactive due to relocation or maintenance, a secondary conveyor will be used.
Initial runoff sediments upgradient of the tailings facility will be captured in a sediment pond located downstream of the tailings stack. An attenuation pond upgradient of the flow-through drains is designed to temporarily store flows from the 100-year, 24-hour storm event and drain within 30 days. Direct runon from the adjacent waste rock pile slopes will be controlled by temporary waste rock berms to direct surface water flows away from the tailings operation.
Surface Water Management For the purposes of stormwater management, the open pit, the heap leach facility, and the plant site are closed systems, with all direct rainfall contained on site. Currently designed stormwater diversions include the flow-through drain system, process water temporary storage (PWTS), and open pit diversions. In addition to the primary diversions, a storage and recovery system sump will be developed in the waste rock storage area. Project water management facilities are intended to have sufficient capacity to handle runoff generated from 100-year, 24-hour storm events. Sediment control facilities are designed to reduce the total suspended solid loads to the minimum practical level for the 10-year, 24-hour storm event, defined as total suspended sold concentrations equal to existing conditions.
Page 3 of 10 Rosemont Copper Project, SPL-2008-00816-MB Section 404 Permit Application
Stormwater flows from the plant site will be collected in the lined PWTS pond, located immediately downgradient of the plant site. The PWTS pond functions as a closed system with all water that is directed to the pond from the plant, in addition to collected stormwater runoff, incorporated into the process water flows.
The buttresses of the dry stack tailings facility will advance ahead of the tailings surface to provide containment while concurrent reclamation and best management practices, such as settling ponds, will be used to limit erosion on the outer slopes. The top of the tailings area is largely impervious and will be sloped inward so precipitation falling on top of active tailings area will remain on top and evaporate. Ponded water may be pumped to the PWTS pond as needed to limit infiltration into the tailings mass. Stormwater management at the waste rock facilities will be similar to that for the dry tailings facility.
Diversions The first phase of the north diversion (Permanent Diversion Channel No. 1), to be constructed by Year 0, channels upland flows into McCleary Canyon north of the plant site. The north diversion is a trapedoizal, riprap lined channel designed to divert stormwater runoff from the 100-year, 24-hour storm event.
Flow-through drains, where possible, will be constructed within existing drainages throughout the dry stack tailings facility and the waste rock storage area. Flow-through drains are porous rock drains that allow stormwater to be diverted underneath the dry stack tailing facilities and waste rock facilities. Selected clean waste rock will be stacked over the top of the rock drain material. The flow-through drains were designed to allow conveyance of the 100-year 24-hour storm volume from the contributing basin through the drain within 30 days.
The open pit diversion collects flows from a small basin west of the open pit and diverts flows away from the pit highwall. The diversion is constructed in two phases with the initial diversion constructed in Year 0. The second phase of the diversion will be constructed in Year 5 as the pit expands and eliminates the initial phase. The design for both phases is a trapezoidal, riprap lined channel designed to divert runoff from the 100-year, 24-hour storm event. Both phases of the diversion channel discharge into a natural drainage west of the heap leach facility.
A typical diversion cross-section is provided in Figure 5, with a typical culvert crossing of the diversion provided in Figure 6.
Ancillary Facilities and Structures The ancillary facilities necessary to support the Rosemont mine and ore processing operations include an administration building, change house, warehouse with lay down yards, analytical laboratory, light vehicle and process maintenance building, mine truck shop, mine truck wash and lube facility, powder magazines and ammonium nitrate storage, and a main guard shack with truck scale. Also included are fuel and lubricant storage and dispensing facilities for mine and process equipment.
Site preparation for the ancillary facilities will include standard grade and fill practices to allow for level surfaces for building construction.
Haul and In-Plant Roads Mine haul roads will be constructed around the north, east, and south edges of the planned ultimate pit limits. Temporary haul roads will be constructed internal to the ultimate pit limits as necessary to provide access to all working faces and to provide connection to the primary crusher, oxide leach pads, and the waste rock storage area located to the southeast, east, and northeast of the pit. Mine haul roads will be constructed using material excavated from the open pit, typically consisting of limestone, skarn, arkose, andesite, and quartz monzonite porphyry rock types. Road surface material may be crushed and screened as needed to produce a smooth running surface. Roads will be slightly crowned to promote drainage of surface runoff to side ditches. Side ditches will funnel stormwater to the flow-through drains or diversion channels. All drainage crossings will be culverted as needed.
Page 4 of 10 Rosemont Copper Project, SPL-2008-00816-MB Section 404 Permit Application
Pit haul roads will generally be 125-ft wide, inclusive of safety berms and ditches, and will support the traffic of 260-T off-highway mine haulage trucks. The gradient for the mine haul roads will vary but will generally be under 10%; short intervals may be constructed as steep as 12%. The minimum inside lane radius for switchbacks within the pit will be 40 ft. Roads will be slightly crowned to promote drainage of surface runoff to side ditches or berms. Safety berms will be constructed to a minimum height of about 6 to 8 ft, the height at the center of the largest truck wheel.
In-plant roads will generally measure 24-ft wide with 5-ft wide drainage channels, as required, along both sides of the road. In-plant roads will extend from the plant entrance around the perimeter of the process facilities and along the crushed ore conveyor to the mine truck shop. An access road will leave the perimeter road at the crushed ore stockpile and serve the fresh water storage tank, potable water tank, and process water tank. All traffic on plant roads will be right hand traffic until reaching the mine truck shop. At this point, traffic will become left hand drive to accommodate haul trucks in the area. An access road will also be constructed between the open pit and the truck shop located near the plant site. This road will have the same design parameters and speed limits as the mine haul roads. Like the open pit and heap leach facilities, the plant site, including in-plant roads will be a closed system with all precipitation and local runoff collected in the PWTS pond and treated as contact water.
Access Roads Access to the property will be via two routes: the primary access route from the east, and a secondary access route from the west. The primary access road to the Property will extend approximately 3.7 mi from SR 83 at a point between mile markers 46 and 47 and end at the main guard building at the entrance to the plant. The main access road will be designed for 35-mph traffic and consist of two lanes, one in each direction. Each lane will be 14-ft wide with a 4-ft wide shoulder, providing a 36-ft wide road bed. Each side of the roadway will have a collection ditch which will typically be 4 ft deep with side slopes of about 2H:1V. The resulting 8-ft wide channel on each side will collect and direct stormwater to diversion channels or receiving waters. The total road corridor, with collection ditches, will be at least 52 ft wide. The access road will be crowned in the center with the surface sloped 2% to each side. The road surface will consist of 8 in of compacted ADOT aggregate (Class 2). The minimum easement for the access road on level ground will be 68 ft, and greater where cut and fill toe lines extend beyond the minimum distance. Fifteen culverts ranging from 30 to 96 inches in size are located along the primary access road and mine access road, as shown in Figure 3. A typical culvert cross-section is provided in Figure 7.
Secondary access to the plant will be provided to the west over the ridge of the Santa Rita Mountains, and will connect to Santa Rita Road at Helvetia Road. This west access road is considered a secondary access for plant maintenance employees to access the fresh water pump stations and pipeline. The design for the secondary access road from Santa Rita Road to the plant entrance is based on one 11-ft wide lane without shoulders, similar to existing FS roads.
Off-site Water and Power Transmission Lines Electrical power will be provided by Tucson Electric Power (TEP) from a link attached to transmission lines on the South Substation loop. The transmission line includes above-ground transmission lines and an associated unpaved maintenance road, with only minor temporary impacts to potential waters of the U.S. In general, it is anticipated that no transmission line poles, substations, or other structures will be constructed in potential waters of the U.S. Impacts to potential waters of the U.S. will occur only from the construction of a 12 foot-wide unpaved access road, and most of these impacts are anticipated to be temporary; that is, where feasible, the potential waters of the U.S. will be restored to preconstruction contours following construction of the transmission lines and access road. The only permanent fill will be the culverted crossings of waters.
The proposed waterline alignment largely parallels Santa Rita Road through the Santa Rita Experimental Range (Figure 2). The pipeline will be constructed with a minimum soil cover of 36 inches within State Land or BLM easements, and 24 inches on the mine property. The pipe bedding requirements will follow
Page 5 of 10 Rosemont Copper Project, SPL-2008-00816-MB Section 404 Permit Application the manufacturer’s recommendations. Isolation valves will be installed in the pipeline at intervals of approximately 3,000 feet and at elevation changes of 250 feet. The pipeline at the wash crossings will be constructed below the calculated scour depth of the wash, and grade control structures will be provided at the largest washes to provide additional protection (Figure 4). Construction of the pipeline will include an unpaved permanent maintenance road and up to five forebay reservoirs and pump stations. The reservoirs and pump stations will be built outside potential waters of the U.S.
BLOCKS 21 and 22 – TYPES OF MATERIAL BEING DISCHARGED AND THE AMOUNT OF EACH TYPE IN CUBIC YARDS AND SURFACE AREA IN ACRES OF WETLANDS OR OTHER WATERS FILLED The types of materials being discharged as a result of the proposed project are listed in Table 1, below. Due to the overall size of the facilities, estimated final volumes or tonnages of the entire facilities are provided.

Project Feature Impacts and Volume of Fill Project Feature Impact/Fill Type Approximate Total Volume Permanent Impact to or Tonnage of Fill Waters (acres) Mine pit Blasted and excavated waste rock N/A 4.4 (consisting of limestone, skarn, arkose, andesite, and quartz monzonite porphyry) Leach pad/Waste rock storage Oxide ore and excavated waste rock 1.3 billion tons 9.0 area Dry-stack tailings facility Native soil and rock, excavated waste 600 million tons 20.7 rock Ancillary facilities and Native soil and rock, excavated waste 2.4 million cubic yards 3.6 structures rock, concrete Access/haul roads Native soil and rock, excavated waste 1.5 million cubic yards 0.8 rock, riprap Water and power transmission Native soil and rock Minor 0.1 lines Total 38.6
In addition, the project is anticipated to result in indirect impacts to approximately 2.5 acres of ephemeral channels by virtue of being cut off from upstream flows (Figure 3). The project will also result in approximately 0.5 acre of temporary impacts resulting from construction of the water and power lines for the project.
BLOCK 23 – DESCRIPTION OF AVOIDANCE, MINIMIZATION, AND COMPENSATION The proposed project has been engineered to avoid and/or minimize impacts to potential waters of the U.S. to the maximum extent practicable. Several aspects of the project have been specifically designed with this goal in mind. The locations of all mine facilities, structures, and associated infrastructure have been chosen to avoid special aquatic sites identified in the vicinity of the project, specifically the wetland feature identified at Scholefield Spring in Scholefield Canyon. Additionally, mine facilities, particularly the tailings facility, have been engineered to minimize their footprints and impacts. The dry-stack tailings design proposed for the project has a smaller footprint than standard tailings, allowing the project to be constructed within a single drainage basin (Barrel Canyon). In addition to these measures, the Applicant will finalize a Habitat Mitigation and Monitoring Plan in conformance with the Corps’ 2008 mitigation rule prior to issuance of the permit. A preliminary mitigation concept has been previously submitted to the Corps.
