MINING METHODS DESCRIBE THE TYPE OF MINING TO BE EMPLOYED [eg. quarry/ truck and shovel operation]: A description of mining operation, while not specifically regulated under SMARA, is provided here for contextual purposes in order to facilitate understanding of this plan. Mining will continue as an open-pit surface mine with benches. Operations will proceed in a single phase utilizing front-end loaders, bulldozers, excavators, scrapers and motor graders. AMENDMENT TO RECLAMATION PLAN MINERAL RESOURCES LLC MORRIS RAVINE MINE May 28, 2015 Page 3 of 12 Mining activities will be initiated by the removal and stockpiling/placement of vegetation and topsoil/overburden which overlie marketable materials. The handling of overburden and topsoil/growth media will be kept to a minimum, and to the extent practicable, overburden and/or topsoil/growth media will be placed in its final configuration at the time it is initially removed. After vegetation and topsoil/overburden is removed, marketable materials will be excavated and delivered to the processing plant by a combination of trucks, bulldozers, scrapers and conveyors. Moving forward, mining cut slopes will be excavated at a maximum slope inclination of 1.5:1 (horizontal:vertical), with benches that are approximately 50 feet high and 20 feet wide. To the extent practicable, slope contouring will occur concurrent with excavation activities. Final reclamation, consisting of final slope contouring and revegetation will commence after final excavation grades are achieved. Mined materials will be processed by a washing/screening/sizing plant to make salable products. Process water will be pumped to ancillary sediment ponds or tanks. Additional processes such as filter press, gravity separation, crushing, scrubbing, flotation and drying will be added as markets for more products are developed.

AMENDMENT TO RECLAMATION PLAN MINERAL RESOURCES LLC MORRIS RAVINE MINE May 28, 2015 Page 4 of 12 DETAILED DESCRIPTION OF RECLAMATION ACTIVITIES [Pursuant to Public Resources Code Section 2772] DESCRIBE THE PROPOSED USE OF THE SITE ONCE MINING CEASES AND RECLAMATION IS COMPLETED: After mining ceases and reclamation is complete, the land will be returned to a condition consistent with its prior land use, open land and grazing. A portion of the land may be returned to higher post-mining uses consistent with the surrounding properties, such as wildlife habitat enhancement area and/or residential. ATTACH EVIDENCE THAT ALL OWNERS OF A POSSESSORY INTEREST IN THE LAND TO BE MINED HAVE BEEN NOTIFIED OF THE PROPOSED END USE (e,g., copies of notices sent to land owner and mineral rights owner).  CHECK BOX IF EVIDENCE IS ATTACHED – The owner’s acknowledgment of the end use is evidenced by the execution of the statement of reclamation responsibility found at the end of this plan. PROVIDE A TIME SCHEDULE FOR THE RECLAMATION OF EACH AREA DISTURBED BY MINING. IF APPLICABLE , INDICATE RECLAMATION PHASES ON YOUR SITE MAP. The estimated date of final reclamation is 20 years from approval of this Plan amendment. Assuming a plan approval date of May 30, 2015, the estimated date of final reclamation would be May 30, 2035. DISCUSS HOW THE IMPLEMENTATION OF THIS RECLAMATION PLAN WILL AFFECT FUTURE MINING IN THE AREA This reclamation plan, with an end use of open land and grazing, will not preclude future mining in the area subject to appropriate entitlements. PURSUANT TO SMARA SECTION 2773, MY RECLAMATION ACTIVITIES WILL COMPLY WITH THE FOLLOWING STANDARDS PROVIDED IN THE CALIFORNIA CODE OF REGULATIONS (CCR), TITLE 14, ARTICLE 9, SECTIONS 3700-3710. CHECK APPLICABLE BOX  TOPSOIL SALVAGE, MAINTENANCE, AND REDISTRIBUTION - IF THE END USE CALLS FOR REVEGETATION OR CULTIVATION OF DISTURBED LANDS, I AGREE TO CONDUCT TOPSOIL SALVAGE, MAINTENANCE, AND REDISTRIBUTION ACTIVITIES IN CONFORMANCE WITH CCR SECTION 3711. Very little topsoil exists on site. Nevertheless, since this plan calls for revegetation, operator will comply with CCR Section 3711 topsoil salvage, maintenance and redistribution practices. Prior to mining marketable materials, topsoil/growth media will be excavated in a separate lift to the extent practicable and stockpiled/segregated (with signage as needed) for use in reclamation (see Figure 2 for approximate stockpile locations). Consistent with MIN 05-01, overburden may also be sold as a product. DESCRIBE HOW THE PROPOSED RECLAMATION OF THE MINE SITE WILL AFFECT PUBLIC HEALTH AND SAFETY, GIVING CONSIDERATION TO THE DEGREE AND TYPE OF EXISTING AND PROBABLE FUTURE PUBLIC EXPOSURE TO THE SITE. AMENDMENT TO RECLAMATION PLAN MINERAL RESOURCES LLC MORRIS RAVINE MINE May 28, 2015 Page 5 of 12 Proposed reclamation to open land and grazing will not jeopardize public health and safety at any time during mining, reclamation or post-reclamation activities. Safety measures such as fencing, signs, and setbacks are implemented as necessary to ensure public safety. The site is restricted to authorized personnel and visitors must check-in prior to entering any operating areas. BRIEFLY DISCUSS HOW CONTAMINANTS WILL BE CONTROLLED AND MINE WASTE WILL BE DISPOSED [eg. fuel storage]. NOTE: IF CYANIDE IS USED FOR ON-SITE PROCESSING, PRC SECTION 21151.7 REQUIRES THE PREPARATION OF AN ENVIRONMENTAL IMPACT REPORT UNDER THE CALIFORNIA ENVIRONMENTAL QUALITY ACT. Fuel and oil will be properly stored consistent with the requirements of a Hazardous Materials Business Plan (“HMBP”) and Spill Prevention Control and Countermeasure Plan (“SPCC”), if required. Cyanide will not be used. Incidental refuse and garbage will be deposited in trash cans and dumpsters and will be hauled off site periodically by a waste management company. Sediments will be controlled through implementation of a Storm Water Pollution Prevention Plan (“SWPPP”), which requires implementation of Best Management Practices (“BMPs”) to eliminate unauthorized non-stormwater discharges, control erosion and minimize discharge of sediment. Process water will be discharged pursuant to Waste Discharge Requirements, and will be managed in a combination of ponds and tanks. A filter press system may be installed to minimize discharges of process water. RECLAMATION STANDARDS CHECK APPLICABLE BOX  REVEGETATION - REVEGETATION WILL BE A PART OF MY APPROVED RECLAMATION PLAN. I AGREE TO CONDUCT MY REVEGETATION ACTIVITIES IN CONFORMANCE WITH CCR SECTION 3705. UNLESS NON-NATIVE SPECIES SUCH AS FORAGE GRASSES OR ORNAMENTALS WILL BE USED, SPECIFY AT LEAST FOUR NATIVE SPECIES THAT OCCUR ON SITE OR IN THE VICINITY OF THE PROJECT AND WILL BE USED FOR REVEGETATION.  CHECK BOX IF THE END USE PRECLUDES REVEGETATION OR THE CULTIVATION OF DISTURBED LANDS.  CHECK BOX IF REVEGETATION IS NOT CONSISTENT WITH THE APPROVED END USE. PROPOSED REVEGETATION PLAN: PROPOSED REVEGETATION MIX: A significant portion of the site has been disturbed by historic mining activities and denuded of topsoil. The remaining undisturbed areas to be mined are covered by thin, poor quality soils. To the extent practicable, available soils will be salvaged and fine sand/clay/silt material from the processing plant may be mixed with overburden materials in an attempt to supplement a soil-like material for use in reclamation. Growth media for revegetation could thus consist of a mix of native topsoil, process fines and overburden, and will be spread across the site prior to revegetation. AMENDMENT TO RECLAMATION PLAN MINERAL RESOURCES LLC MORRIS RAVINE MINE May 28, 2015 Page 6 of 12 The site is intended to be planted with a vegetative cover (erosion control mix and trees/shrubs) capable of self-regeneration without dependence on irrigation, soil amendments or fertilizer. Mine floor areas that are relatively level and suitable for grazing will be seeded with an erosion control seed mix only. No trees or shrubs will be planted on the level areas as they will be used as grazing land. Mine slope areas (1.5H:1V or flatter) and benches will be planted with an erosion control mix as well as trees/shrubs consistent with an end use of open land. Benches will be revegetated with trees/shrubs as part of final reclamation only in order to preserve their function as temporary haul roads if needed during mining operations. The erosion control seed mixture will consist of brome, California oats, zorro fescue common vetch, crimson clover, and California field flowers. This seed mix is selected to provide fast and permanent cover sufficient to stabilize the surface against effects of long-term erosion and will be similar to naturally occurring habitats in the surrounding area. Modifications to this erosion control seed mix may be appropriate based on availability from suppliers, cost, and species determined most suitable at the time planting occurs. Ideally, revegetation will occur between September and November, and include application of mulch and fertilizer. Any necessary soil amendments will be applied according to manufacturer’s specifications. The performance standard for successful revegetation with an erosion control mix will be 75% cover with at least three species types. In addition to the erosion control mix, seeds will also be collected from trees and shrubs – oak, pine, toyon, buckeye, bay laurel, and other native species – on the site and broadcast over the reclaimed slope areas each fall. If native seed application is determined to be impractical, then pine and oak seedlings may be purchased from and/or germinated at a local nursery and planted during reclamation. Tree and shrub stocking rates for slope areas (±40 acres slopes and ±10 acres benches) are intended to allow re-forestation to levels that are consistent with that which existed prior to mining disturbances. Baseline conditions at the site represent about 5 trees per acre less than 2” diameter at breast height (“dbh”), and about 19 trees per acre greater than 2” dbh (Glazner 1999). Consistent with UP 93-36, trees less than 2” dbh will be replanted at a 1:1 ratio and trees greater than 2” dbh will be replanted at a 2:1 ratio. Based on these requirements, a minimum of 43 trees per acre will be planted. For tree/shrub plantings, the performance standard for successful reclamation will be a replanting success rate of 80%, or at least 34 trees/shrubs per acre after the third year of planting. Since grazing activities are not anticipated to threaten the success of the proposed slope revegetation, planted trees and shrubs will not require fencing, caging, or other protection measures. AMENDMENT TO RECLAMATION PLAN MINERAL RESOURCES LLC MORRIS RAVINE MINE May 28, 2015 Page 7 of 12 During the revegetation establishment period, noxious weeds will be managed: (1) when they threaten the success of the proposed revegetation; (2) to prevent spreading to nearby areas; and (3) to eliminate fire hazard. Noxious weeds will be removed using a combination of herbicides, mechanical controls, and hand weeding. In some cases, complete eradication may not be practicable unless the weed-infested patches are small. At owner’s discretion, access roads and existing roads used for ingress/egress may remain following reclamation to facilitate the proposed end use. If removed, roads will be stripped of any roadbase materials and covered with suitable growth media or topsoil, and replanted or revegetated consistent with the erosion control seed mix described above. Revegetation monitoring will be conducted on an annual basis for a minimum of two years. The monitoring program shall be considered complete if during the last two years plantings required no human intervention. If intervention is necessary after the second year of monitoring, then remedial measures will be implemented and monitoring will continue until such time as the performance standards can be met or this plan is modified. SUCCESS OF REVEGETATION WILL BE JUDGED UPON THE EFFECTIVENESS OF THE VEGETATION FOR THE APPROVED END USE AND BY COMPARING QUANTIFIED VEGETATIVE COVER, DENSITY, AND NUMBER OF SPECIES OF THE RECLAIMED MINED LANDS TO LOCAL AREAS OF NATURALLY OCCURRING VEGETATION OR PRE-MINING CONDITIONS (BASELINE).

Reclamation is not expected to impact wildlife species or habitats. See Section 4.4, Biological Resources, of the “Initial Study and Proposed Mitigated Negative Declaration” dated December 6, 2006, prepared in support of MIN 05-01. Wildlife and wildlife habitat will be protected in accordance with California Endangered Species Act, Fish and Game Code, and federal Endangered Species Act requirements. CHECK APPLICABLE BOX  BACKFILLING, REGRADING, SLOPE STABILITY, AND RECONTOURING - I AGREE THAT ALL BACKFILLING, REGRADING, SLOPE STABILITY, AND RECONTOURING WILL CONFORM WITH CCR SECTION 3704. This plan has been prepared giving specific consideration to the proposed end use of open land and grazing. The current mine and surrounding areas were heavily mined during the past 150 years, and the current landscape is dominated by steep slopes and generally rugged terrain. Final cut slopes will be left at a maximum slope inclination of 1.5H:1V, consistent with Sierra Pacific Group’s slope stability analysis conducted in 1999 (see Appendix B, Slope Stability Analysis). Final reclaimed fill slopes, if any, will not exceed 2H:1V. Please see Figure 3, Reclamation Plan and Figure 4, Reclamation Plan Cross Sections. Some existing interim mining slopes in the Ione formation (generally north of the plant site) are standing at steeper than 1.5H:1V. Final reclaimed conditions of these slopes will be 1.5H:1V or flatter (consistent with Sierra Pacific Group’s slope stability analysis), unless additional slope stability analysis is conducted that indicates that a steeper slope will have an adequate factor of safety for the proposed end use. Overburden (including any mine waste rock) may either be sold as a product or used in reclamation. Where used in reclamation, overburden will be spread across mined surfaces, backfilled in the mine floor, or left in designated permanent overburden storage areas (see Figures 2 and 3). Overburden storage areas will be compatible with the end use, conformed to the surrounding topography to the extent practicable, and stabilized with an erosion control seed mix. BMPs will be implemented consistent with the site’s SWPPP. Process and storm water ponds ancillary to mining operations will be stabilized with BMPs and left in place following reclamation. AMENDMENT TO RECLAMATION PLAN MINERAL RESOURCES LLC MORRIS RAVINE MINE May 28, 2015 Page 9 of 12 Backfill is not proposed for urban use or resource conservation purposes. Backfill, consisting of the permanent placement of a mixture of overburden and silty clay material from the processing plant, will be performed using mobile equipment such as scrapers, compactors and bulldozers that will provide an appropriate level of compaction for the potential end use.  CHECK THIS BOX IF FINAL RECLAIMED FILL SLOPES, INCLUDING PERMANENT PILES OR DUMPS OF MINE WASTE ROCK AND OVERBURDEN, WILL NOT EXCEED 2:1 (HORIZONTAL:VERTICAL).  CHECK THIS BOX IF FINAL RECLAIMED FILL SLOPES, INCLUDING PERMANENTPILES OR DUMPS OF MINE WASTE ROCK AND OVERBURDEN, WILL BE : [INDICATED SLOPE RATIO] WHICH IS STEEPER THAN 2:1 (HORIZONTAL:VERTICAL).
