Annual Reclamation Report 2 December 31, 2018

11.0 INTRODUCTION

This report summarizes exploration drilling, reclamation and care and maintenance activitiesconducted during the 2018 field season at the Pebble Project, a mineral exploration and development project operated by the Pebble Limited Partnership (PLP). PLP is a U.S. company wholly owned by Northern Dynasty Minerals Ltd. of Vancouver, Canada, conducting exploration-related activities on state mineral claims leased to the Pebble East Claims Corporation and Pebble West Claims Corporation. These activities are authorized by Miscellaneous Land Use Permit (MLUP) No. 6118 issued by the Alaska Department of Natural Resources, Division of Mining, Land and Water (ADNR-MLW).

During 2018 PLP drilled 28 new exploratory boreholes. Monitoring equipment was installed at 27 of these sites, while the remaining site was plugged and closed according to MLUP 6118 closure requirements. Repairs were conducted at two former drill sites. Total disturbed area from 2018 activity was less than one-tenth of one acre (0.091 acres). All disturbed areas have been fully reclaimed in accordance with AS 27.19 and 11 AAC 97.

In addition, PLP conducted minor repair and maintenance activities such as cap replacement and snow pole installations at existing monitoring wells and inspected 540 sites to ensure compliance with MLUP 6118 stipulations. Field season operating days totaled 183, from May 1 through October 31, 2018.

1.1 LOCATION

The Pebble Project is located in the Lake and Peninsula Borough in southwest Alaska. The main deposit is centered approximately 200 miles SW of Anchorage, 60 miles W of Cook Inlet and 17 miles NW of Iliamna (Figure 1). The Pebble Project comprises 2,403 Alaska state mineral claims and contains one of the world’s most significant undeveloped deposits of copper, gold, and molybdenum (Figure 2).

1.2 RECLAMATION OBJECTIVES AND REQUIREMENTS

Alaska statute (AS 27.19) and regulation (11 AAC 97) require mining operators to reclaim any disturbed land to a “stable condition”, which means rehabilitation to a state that allows for the reestablishment of a vegetative cover within a reasonable period of time. MLUP No. 6118,Section 1 identifies reclamation requirements, including:

Surface disturbance shall be held to a minimum, and will be reclaimed by backfilling, contouring, and spreading of organic rich overburden to promote stabilization and natural revegetation.

The area reclaimed shall be reshaped and recontoured to blend with surrounding physiography using strippings and overburden, and then stabilized to a condition that shall retain sufficient moisture to allow for natural revegetation.

Upon completion of drilling activities, drill pads shall be reclaimed as necessary, including reseeding, to encourage natural revegetation of the sites and protect them from erosion.



All drill hole casings shall be removed or cut off at, or below, ground level unless otherwise specifically approved by the Division of Mining, Land & Water.

All drill holes shall be plugged with bentonite hole plug, a benseal mud, or equivalent slurry, for a minimum of 10 feet within the top 20 feet of the drill hole in competent material. The remainder of the hole will be backfilled to the surface with drill cuttings.

MLUP No. 6118 also requires the filing of this reclamation report and Annual Reclamation Statement by December 31 of each year the permit is in effect.

MLUP No. 6118 also includes multiple special stipulations addressing:

Action Requirements on Inspection Reports (Special Stipulation B)Mineral Closing Order 393 (D) Bristol Bay Area Plan requirements (E) Wildlife Management (F-I) Drilling Waste and Cuttings Management (J)Site Monitoring, Maintenance, and Reporting (K-L) Water Use (M)

Activities for special stipulations B and D–M are described in Section 3.9. Water use (M) is summarized in Section 3.5. The entirety of this report satisfies Special Stipulation L (Annual Report).

11.3 WORK SUMMARY

Work conducted during the 2018 field season included:

Drilling, installation and reclamation of 27 new geotechnical monitoring wells. Drilling, plugging, and reclamation of one new geotechnical drill site. Repairs to drill sites 3127 and GH08-156. Routine maintenance (e.g., safety marker replacements, plug/cap maintenance, security controls). Continued monitoring of select sites to evaluate revegetation success and previous repairs.Routine inspection of 540 selected drill sites and field installations.

New drill sites are summarized on the Drill Sites tab in the attached AHEA Reclamation Spreadsheet (Appendix D) and shown on Figure 4. Inspections and site status are presented in Appendix C. Representative photographs are included in Appendix A. Repair sites are summarized in Table 1 and described in Section 3.4.



Table 1. 2018 Repair Site Summary

11.4 OTHER PERMITS AND REGULATORY REQUIREMENTS

PLP obtained Temporary Water Use Authorizations (TWUA) and Fish Habitat Permits to support exploration and repair work conducted in 2018, as shown in Table 2. A consultant working under contract to PLP (Stephen R Braund and Associates) obtained a cultural resources investigation permit from the state Office of History and Archaeology (OHA) to survey areas where ground disturbances may occur. All compliance reporting for cultural survey work is filed by the consultant directly to OHA.

Table 2. 2018 Permits and Authorizations



22.0 PROJECT DESCRIPTION

2.1 SITE ACCESS

Field operations are based out of PLP’s office at the Iliamna Airport in Iliamna, AK. Access to all worksites within the Pebble deposit is by helicopter only. PLP does not use ground vehicles to access the deposit area or travel between worksites. As a result, the deposit area remains free of temporary roads and tracks.

2.2 ENVIRONMENTAL CONTROLS

2.2.1 Vegetation and Tundra Preservation

PLP’s standard field work procedures require the use of wooden tundra pads and platforms for all heavy equipment and materials to minimize vegetation impacts. Individual worksites are also organized to have as small a footprint as possible, with mobilization and demobilization occurring within the shortest time frame to limit duration impacts. When a surface disturbance is necessary, groundcover, including vegetation, is removed and stockpiled for later use in reclaiming the site. Once the activity is complete, excavated areas are backfilled and re-covered with reserved tundra. Disturbed areas are also revegetated with native seed or an approved seed mixture as appropriate.

2.2.2 Fuel Management and Spill Prevention

PLP uses double-walled, welded aluminum fly tanks to transport and store all fuel for field operations. Tanks are filled at PLP’s Iliamna location to no more than 80 percent of the total capacity. (Most tanks used have a total capacity of 110 gallons, meaning each will contain no more than 88 gallons.) Each tank is visually inspected for leaks or spills prior to transport by helicopter. A separate, double walled 500-gallon storage tank is maintained with fuel at the MSD during the active field season. All residual fuel was drained prior to winterizing field operations.

All active fuel tanks are placed in welded aluminum containments sized to hold 110 percent of the tank’s maximum capacity. Containments are placed on level ground at least 100 feet from any surface water.

Each tank location is stocked with a spill containment and cleanup kit. All field staff have been trained in the proper response and reporting protocols as part of PLP’s SPCC Plan. PLP also maintains a contract with Alaska Chadux Corporation to provide 24-hour spill response, if necessary. After each worksite is demobilized, the area is inspected to ensure no leaks or spills occurred.

2.2.3 Erosion and Sediment Control

Certified weed-free straw was used in conjunction with re-seeding efforts at multiple locations to minimize wind and water erosion and promote more thorough vegetation growth.



22.3 MATERIAL & EQUIPMENT STAGING

2.3.1 Main Supply Depot

The Main Supply Depot (MSD) was initially constructed in 2004 and serves as the primary storage and staging area for field operations. The site occupies approximately 2.5 acres of a gravel bluff in the West Deposit area (SE1/4 SE1/4 of Sec 21, T3S R35W and the NE1/4 NE1/4 of Sec 28, T3S, R35W) (ADL Nos. 516811 and 516874).

Multiple temporary wood frame buildings (including West Bay 4 building) and platform tents provide sheltered storage for machinery, drilling equipment, environmental supplies, and variety of small parts and tools. Small quantities of drilling fluids, motor oils, and antifreeze are stored in sealed, original packaging inside weather-proof shelters. All temporary structures are constructed on elevated platforms or placed on tundra pads. Other items such as drill rods, lumber, tundra pads, outhouses, fuel containments, rig supports, are stored within the MSD yard on racks or elevated platforms.

The MSD was used as the primary staging area for 2018 field activities. At the end of the season, all fuel was removed from the site.

2.3.2 Fuel Storage

Jet A fuel is used for all large mechanized field equipment (pumps, generators, drill rigs). Multiple aluminum fly tanks were transported to and stored at the MSD by helicopter to support 2018 field operations in accordance with PLP’s fuel management policies (Section 2.2.2). The maximum volume of fuel stored at the MSD during 2018 was approximately 1000 gallons. Smaller volumes of fuel were transported to individual work sites as necessary and stored appropriately (aluminum containments, spill kits). All aluminum fly tanks were removed to Iliamna at the end of the 2018 field season. No fuel or other petroleum product spills were identified or reported during the 2018 field season.

2.3.3 Watershed

The Watershed site is located approximately 0.75 miles east of the MSD in the SW1/4 SE1/4 of Sec 22, T3S, R35W (ADL No. 524712). The site consists of three temporary buildings constructed on elevated platforms: one Quonset-style building with a corrugated metal roof (14’ x 16’) that serves as a light machine shop, and two wood frame buildings (9’ x 38’; 10’ x 16’) used to store hoses, miscellaneous hand tools and field supplies. A small generator shed is attached to the Quonset hut. One 110-gallon fuel tank (empty) is kept in an aluminum containment next to the shed.

PLP continues to use the Watershed site as a storage location for field equipment and light machine shop during all months of the year.

2.3.4 West Bay 1 and 3

Each West Bay location consists of two temporary wooden structures (an 8’ x 12’ emergency shelter and a smaller generator shack). These structures are used to provide shelter for monitoring crews during data collection. West Bay 1 is located in the SW1/4 SW1/4 of Sec 23, T3S, R35W



(ADL No. 524714). West Bay 3 is located in the NE1/4 SW1/4 of Sec 33, T3S, R36W (ADL No. 642412). PLP continues to use both West Bay locations to store field equipment.

Note: The facility previously identified as West Bay 4 remains in place, but due to its location within the footprint of the MSD it is not inventoried as a separate field site.

22.3.5 Meteorological and Communications

The Pebble 1 meteorological station is located in the SW1/4 NE1/4 of Sec 20, T3S, R35W (ADL No. 524829). The small site consists of a temporary fiberglass structure (approximately 8 x 8 ft) and associated equipment.

The Koktuli Mountain radio repeater is located in the NE1/4 SW1/4 of Sec 36, T3S, R35W (ADL No. 646608). The small site consists of a temporary metal structure (approximately 8 x 8 ft) and associated equipment.

PLP continues to use the Pebble 1 met station to collect basic meteorological data, while the Koktuli Mountain repeater remains the primary means of communication with helicopters and field crews.

2.3.6 Acid Rock Drainage Test Location

The ARD site is located in the SE 1/4 SE 1/4 of Section 22, T3S, R35W (ADL No. 524713). It was set up to evaluate real time weathering and acid generation potential in area rock. The site consists of 12 large plastic barrels filled half way with rock fragments. Barrels are racked on wood tundra pads.

When testing is not active, each barrel is covered with a 40-mil HDPE tarp to prevent water intrusion. Aluminum plates (3/8-inch or 1/4-inch thick) are also placed on top of each barrel and secured with straps to guard against wind and wildlife damage. Drainage tubes are also sealed to prevent leakage.

During the 2018 field season, the ARD test site was active from June through September. The site has been secured as described above for the 2018/2019 winter. Testing is scheduled to resume in spring 2019.

2.4 FIELD STAFF AND LOGISTICS

All work crews are based out of Iliamna and ferried to the work site by helicopter each day work is being performed. All waste is removed from the field and properly disposed in Iliamna.



33.0 FIELD ACTIVITIES

3.1 EXPLORATION ACTIVITY

PLP conducted new geotechnical drilling at 28 new sites in 2018. Six sites were drilled using a diamond core drill; the remaining 22 sites were drilled using a sonic drill. Core samples from all boreholes were removed for analysis at PLP’s Iliamna facility.

Monitoring instrumentation installed at 27 sites. These sites remain active and are used to periodically collect groundwater data required for baseline studies and engineering designs. Casing installation failed at one location (GH18-401S). As a result, this site was plugged and closed according to MLUP 6118 requirements.

Boreholes drilled in 2018 and their status are listed on the Drill Sites tab in the attached AHEA Reclamation Spreadsheet (Appendix D).

3.2 SURFACE DISTURBANCE AND RECLAMATION

Surface disturbances during the 2018 field season totaled 0.0912 acres, or 3,974 square feet. All disturbed areas have been reclaimed; 0.0 acres remain disturbed.

Each site was surveyed and photographed before drilling was initiated. Locations for sumps and the general site layout were recorded. Sump locations were selected and sized to enable sufficient infiltration without overflow. In many cases, sumps are shared between nearby drill sites to minimize the overall disturbed area (see Appendix D, Sump Pits).

The disturbed area for a particular site is calculated using GPS coordinates or field measurements taken by staff. Disturbed areas typically included one or more sumps, plus a collection trench that drains produced water from the borehole to the sump. PLP does not discharge any produced water to surface waters; no discharge trenches are excavated.

Prior to drilling, sumps and the collection trench were excavated either by hand or using a small Kubota excavator. Excavated material was segregated according to content, with vegetative cover removed in segments and preserved on fabric mats. Bulk soil was stockpiled on a separate fabric mat as close as possible to the original excavation. On average, collection trenches are roughly 15-inches wide. Individual sump pits are generally excavated to a depth of three feet with a surface area of 40-60 feet. Sump pits were monitored during drilling to ensure water does not overtop and discharge to the surrounding ground.

When drilling was complete at each site, all equipment and tundra pads were removed by helicopter. Reclamation crews inspected the site for any inadvertent spills and collected all debris, which was removed to PLP’s Iliamna facility for proper disposal. Any cuttings remaining on the surface were collected and placed in the sump for burial as required. All soil was returned to the excavation source and mounded above the surrounding ground to shed surface water. Salvaged vegetation was replaced atop the excavated trench or sump where practical.



Each disturbed area will be inspected in the subsequent field season to evaluate reclamation success and the need for any enhancements.

Disturbed area totals for each drill site are summarized on the Sump Pits tab in the attached AHEA Reclamation Spreadsheet (Appendix D). Photos of reclaimed sites are included in Appendix A.

33.3 CLOSURE SITES

3.3.1 Borehole GH18-401S

Following initial drilling for borehole GH18-401S, the monitoring well casing (PVC) was damaged during extraction, rendering the borehole inoperable for monitoring. Artesian conditions were not encountered.

The borehole was plugged using approximately 65 cubic feet of a bentonite grout mixture. Grout was injected from the terminal depth of 171 feet below ground to the surface. The surface area was reclaimed by replacing reserved vegetation and stabilizing exposed soils. The site will be monitored in subsequent seasons to ensure reclamation success.

Photos of Borehole GH18-401S are shown in Appendix A.

3.4 2018 REPAIR SITES

Maintenance activities were conducted during the 2018 field season (June – October). In addition to the 28 exploration drill sites, repairs were made to two existing sites as described below.Representative photos for re-drilled/grouted sites are provided in Appendix A.

3.4.1 Borehole 3127

This site was first repaired in 2016 by backfilling with bentonite pellets (see 2016 Annual Reclamation Report). These repairs were initially successful but subsequent inspection in spring 2017 showed that minor upwelling (approximately 1 gallon per minute [gpm]) had recurred. Water quickly dissipates into the surrounding tundra. PLP’s drilling contractor (Foundex Pacific) made two attempts to re-drill and grout the site in 2017, with limited success. Water flow was reduced but not completely cut off.

In 2018, the contractor again attempted to plug the borehole by drilling a vertical hole to intersect the original borehole (drilled at -49°angle) at the bedrock layer. Water was encountered at 53 feet below the surface. The new borehole was then pressure grouted using a mixture of cement (type 10), barite, and bentonite. The total volume of material was approximately 45 cubic feet.

A site inspection the following week confirmed that a small volume of water was still being produced despite the new repair effort. Water consistently flows at less than 1 gpm and dissipates into the surrounding ground within a few feet. There is no discharge to surface waters.

PLP has advised ADNR staff of continued repair efforts and jointly inspected the site in July 2018. PLP has retained the services of other drilling contractors who are developing an alternate



plugging and closure plan to eliminate all water flow. This plan will be submitted to ADNR for review by March 29, 2019.

33.4.2 GH08-156

This site is located on a hillside that experiences fairly consistent sheet flow at the surface. As a result, the surrounding ground is often saturated for long periods during the summer and fall. This site was identified in 2016 as a potential repair site due to water observed around the base. Inspection by PLP’s drilling contractor determined that water was not originating from the borehole, but was instead flowing from upgradient areas and pooling in the small depression around the casing. To confirm this assessment, PLP decided to permanently close the site by removing the aboveground casing backfilled the borehole with bentonite. The site was allowed to stabilize for several days and re-inspected.

The site was re-inspected in spring 2018 at which time some of the bentonite material had been flushed from the top of the borehole. The water source appears to be from the surface, but volumes may be sufficient to scour the material during runoff. In August 2018, PLP conducted additional repairs to the site by re-defining the top of the borehole, removing excess material, and pouring quick-release bentonite pellets down the hole. The pellets congealed successfully,forming a cap over the borehole area that allows water to flow across the surface without ponding or scouring.

The site will be re-inspected in 2019 to verify this repair effort. If similar scour effects are observed, PLP will consult with ADNR to identify alternative reclamation measures.

3.5 CONSUMPTIVE WATER USE

All consumptive water use was authorized by Temporary Water Use Authorizations issued by ADNR. Water use is summarized by intake point on the Water Sources tab in the attached AHEA Reclamation Spreadsheet (Appendix D).

One submersible borehole pump with the maximum pumping capacity of 25 GPM was used at each drill rig location. Each pump is affixed with an 18-inch distribution sleeve which has been certified by ADF&G for use in water bodies containing Group A fish (fry stage whitefish) or larger. The screen maximum approach velocity is 0.1 feet per second and has an outer mesh covering of 1mm x 12mm, slotted.

3.6 INVESTIGATION SITES

3.6.1 Borehole 9475

This site is located in the East Deposit area and was previously used for long-term monitoring. Upwelling was first observed in 2014, with an initial repair attempt made in fall 2015. Repairs at that time were unsuccessful, as upwelling had resumed by spring 2016. Additional repairs were attempted in 2017 by pressure grouting the original borehole to a depth of 102 feet with approximately 160 cubic feet of grout mix. Water flow was cut off and the site reclaimed.



In spring 2018, the site was re-inspected and observed to be producing water at an approximate rate of 2 gpm before dissipating into the ground approximately 130 feet downgradient. Grout material had been flushed to the surface by artesian pressure in late winter/early spring 2018. All flushed material was removed and disposed of off-site. The site was reclaimed and stabilized to prevent erosion and sediment loss.

PLP and ADNR jointly inspected the site in July 2018. PLP has retained the services of other drilling contractors who are developing an alternate plugging and closure plan to eliminate all water flow. This plan will be submitted to ADNR for review by March 29, 2019.

33.7 STATE INSPECTION

DNR staff conducted three separate inspections during 2018. DNR-Mining staff inspected the site on July 27 and August 21. DNR-Water staff inspected the site on October 8. PLP staff participated in each inspection.

As of the date of this Annual Reclamation Report (December 31, 2018), DNR has only made the July 27 inspection report available for review. Minor findings from this report (missing caps) were addressed by PLP and reported to ADNR. PLP will address any findings from the remaining reports when they are made available.

3.8 INTERNAL INSPECTIONS

PLP conducts routine inspections of project drill sites during each field season to ensure compliance with all permit and regulatory requirements. Information is summarized and provided to DNR, including current status, repair or maintenance needs, presence of above ground structures, reclamation status, safety markings, and abandonment method, if applicable.

PLP assigns an alpha-numeric code to each drill site following inspection to more easily characterize each location and plan future maintenance and inspection needs. Numerals (1-3) describe the borehole operating status (e.g., active or potential use for monitoring or future drilling) while letters (A-E) describe the surface condition, including reclamation status and maintenance needs, if any. A detailed explanation of each code is provided in Appendix B.

During the 2018 field season, PLP inspected 540 individual borehole locations. The status of each project borehole inspected in 2018 is provided in Appendix C.

As shown in Table 3, nearly all sites (99 percent) are in stable condition and require no further action (D and E). Three sites require follow up inspection or maintenance (C), while two additional sites require repairs to control minor upwelling (B). None of the project drill sites require major repairs (A) or otherwise pose a notable risk of causing adverse impact.

Inspection Categories



TTable B-1. Borehole Status Codes

Code Category Description1 Active Primary designation for active monitoring wells (groundwater quality, geotechnical, etc.).

Also used for some former exploration boreholes that are maintained as possible water sources. Active sites do not have material plugs (grout, cement, bentonite) but may be fitted with mechanical plugs or caps.

2 Inactive Site is not currently used as monitoring/study location, but is preserved for potential future use (e.g., additional drilling, water source). Inactive sites maintain aboveground structures (casing, valves, caps).

3 Closed Site is fully decommissioned. Borehole has been plugged as appropriate. All surface structures removed, with possible exception of wood post indicating location and borehole ID.

Table B-2. Reclamation/Maintenance Condition Codes

Code Category Description

A Major Repairs

Site condition presents an identified environmental compliance or health & safety concern, or is at risk of progressing if not addressed as soon as possible. Significant repairs necessary, typically requiring advanced planning, technical staff and additional equipment. Coordination and approval from DNR or other agency may be required.

Examples: upwelling of discolored or voluminous water; discharge to surface water. B Minor repairs Site condition requires repairs or rehabilitation, but is stable and not at risk of deteriorating further. Work

does not require technical staff but generally cannot be completed during routine maintenance trips or by one person. Advance approval from DNR or other agency is usually not required unless circumstances dictate. All repair activities summarized in annual report.

Examples: Margo plug replacement/installation; large area rehabilitation or revegetation efforts; grout injection.

C Routine Maintenance or Additional Investigation

Maintenance requirements are small or insignificant and generally the result of normal operation or exposure to elements. Repairs can be completed by staff during routine inspections and do not require specialized equipment or advance planning. Also used to identify sites where condition cannot be confirmed, thus requiring additional inspection or involvement of higher level staff.

Examples: application of sealant around cap; water valve replacement; ponded surface water with unconfirmed source.

D Stable/Monitored

Site condition is stable and has been fully reclaimed, but with past maintenance issues or known to have higher maintenance needs. All structural equipment, if any, is in good condition. Routine monitoring is generally more frequent than Category E sites.

Examples: artesian sites; sites with recent, major repairs.E Stable/

No ActionSite condition is stable and has been fully reclaimed. All structural equipment, if any, is in good condition. No known issues. No history of upwellings, leaks, or staining. Located in an area unlikely to cause concern (e.g., wetlands, artesian zone). Inspection frequency is lower than Category D sites.

In accordance with AS 27.19 (Reclamation Act):

I, hereby file an annual reclamation statement for the 2017 mining operation described in subject Application for Permits to Mine in Alaska. (Submission of this statement does not constitute reclamation approval.)

Volume of material disturbed in 2018: cubic yards (includes strippings and processed material).

Sluice days last season: Cubic yards of material processed daily: Annually : .

Total acreage disturbed in 2018: acres. (Includes stripped areas, mining cuts, overburden and tailing stockpiles and disposal areas, temporary stream diversions, stream bypasses, and settling ponds). Federal operators should include area of camp and access roads.

Length feet and Width feet of stream diversion.

Stream diversion: Temporary Permanent (check one).

Total area reclaimed in 2018: acres.

(This should match "total acreage currently disturbed" on the 2019 Reclamation Plan Form.)

Total un-reclaimed acres:

Spread and contoured tailings

Spread topsoil, vegetation, overburden muck or fines on the surface of contoured tailings

Reestablished flood plain with stream channel in stable position

RECLAMATION PLAN (33) RECLAMATION PLAN LETTER OF INTENT TO DO RECLAMATION

(Disturbed Area 5 Acres Or Greater or BLM Notices) (Disturbed Area Less Than 5 Acres) In accordance with Alaska Statute 27.19, reclamation is required of all mining operations. Reclamation bonding is required of operations with disturbance of 5 acres or greater. Completion of this application will meet the requirements for a "Reclamation Plan" for operations 5 acres and larger in size and for a "Letter of Intent To Do Reclamation" for operations under 5 acres. If you do not intend to use the reclamation methods presented below, you must provide additional information concerning your plans for reclamation under separate attachments.

BLM requires that the reclamation plan be consistent with §43 CFR 3809.420, Performance Standards for the Surface Management regulations for Federal Operations. Refer to 43 CFR 3809 or the BLM minerals website available at http://www.blm.gov/ak/st/en/prog/minerals.html for more information on what is needed for a reclamation plan on Federal lands.

Total acreage currently disturbed: acres. This should match: "Total Unreclaimed Acres" on your 2018 Annual Reclamation Statement for Small Mines, or line #7 on your 2019 Bond Pool Renewal Form. Disturbed ground includes all unreclaimed mining and exploration activity (excluding camps and roads) since October 1991. Federal operators must include areas of camps and roads.

New acres to be disturbed in 2019 acres. Total acreage (currently disturbed plus new acres): acres.

Acreage disturbed by land status: State (general) State (Mental Health) Private Federal

Total acreage to be reclaimed in 2019: acres; Total volume of material to be disturbed in 2019:

Include strippings and overburden to be removed. Cubic yards = Length (yards) x Width (yards) x Depth (yards).

(These measures are required by law. Those that do not apply may be crossed out; but, an explanation must be given as to why these

measures are not necessary at your site.)

Topsoil, vegetation, and overburden muck, not promptly redistributed to an area being reclaimed, will be individually separated andstockpiled for future use. This material will be protected from erosion and from contamination by acidic or toxic materials and will notbe buried by tailings.

The area reclaimed will be reshaped to blend with the surrounding area using tailings, strippings, and overburden and be stabilized. Stockpiled topsoil, overburden muck, will be spread over the contoured exploration sites to promote natural plant growth such that

the area can reasonably be expected to revegetate within five years. Stockpiled vegetation will be spread over topsoils. Exploration trenches will be backfilled. Brush piles, stumps, topsoil, and other organics will be spread on the backfilled surface to

inhibit erosion and promote natural revegetation. Exploration trenches shall be flagged and signs posted to notify the public of theexistence of the open trenches. All exploration trenches shall be reclaimed by the end of the exploration season in which they areconstructed, unless specifically approved by the DMLW.

Shallow auger holes (limited to depth of overburden) shall be backfilled with drill cuttings or other locally available material in sucha manner that closes the hole to minimize the risk to humans, livestock and wildlife.

All drill hole casings shall be removed or cut off at, or below, ground level. All drill holes shall be plugged by the end of theexploration season with bentonite holeplug or equivalent slurry, for a minimum of 10 feet within the top 20 feet of the drill hole. Theremainder of the hole will be backfilled to the surface with drill cuttings. If water is encountered in any drill hole, a minimum of 7feet of bentonite holeplug or equivalent slurry shall be placed immediately above the static water level in the drill hole. Completefilling of the drill holes, from bottom to top, with bentonite holeplug or equivalent slurry is also permitted and is considered to be thepreferred method of hole closure during which they are drilled, unless otherwise specifically approved by the DMLW.

If artesian conditions are encountered, the operator shall contact the DMLW (Kindra Geis (907) 451-2790) and the DEC (Tim Pilonat (907) 451-2136) for hole plugging requirements.

All buildings and structures constructed, used or improved, on State land, will be removed, dismantled, or otherwise properlydisposed of at the completion of the activity. The campsite will be cleaned up and left free of debris. In consideration of potentiallysignificant historic properties/cultural resources, do not remove or disturb any buildings, structures, objects, or artifacts that werelocated on the site prior to the current operation without preauthorization from SHPO (Contact Mckenzie Johnson of SHPO at (907)269-8726 or [email protected] ).

IMPORTANT: 1. Alternative reclamation measures may be approved if the reclamation measures presented above are not applicable to your site. Please explain in separate correspondence. Submit a sketch and describe additional reclamation measures you propose to conduct at your operation. Reclamation measures must comply with AS 27.19. 2. Federal land managers may require reclamation measures different to those identified above.

BONDING: In accordance with AS 27.19, bonding is required for all operations having a mined area of > five acres on State Land. This area must be bonded for $750.00 per acre, unless the miner can demonstrate that a third party contractor can do the needed reclamation for less than that amount. A Statewide bonding pool has been established and may be joined by completing the bond pool application form. No reclamation plan approval goes into effect until the bonding pool deposit and annual nonrefundable fee are paid. Federal land managers may have additional bonding requirements. Use bond form to calculate area of disturbance for bonding.
