I Final Plan Format and Context
The Review of Land Use and Final Plan for Land Use Permit W2009X0002 has been prepared to provide a synopsis of the history of the land use area, a review of the chronology of the issuance of the Land Use Permit (LUP), a review of the intended/actual land use at the site and a plan describing actual land use within the permitted area. The intent of this Plan is to provide the context of the LUP application/issuance, describe the intended activities (as provided in the application) compared to the executed activities and provide the Final Plan as required under Section 33 of the Territorial Land Use Regulations.
II Background
The North Inca Mine was an advanced gold exploration property that operated between 1945 and 1949. On-site exploration activities included geological mapping, surface diamond drilling (9,700 metres (m)), sinking an exploration shaft to a depth of 98 m, and underground diamond drilling (2,800 m). Review of site records indicates that there had not been significant exploration activity on-site between 1949 and the remediation of the North Inca site. The Department of Indian Affairs and Northern Development (DIAND) Contaminants and Remediation Directorate (CARD) oversaw the assessment and remediation of the North Inca Mine site. The location of North Inca is provided on Figure 1. The configuration of the Colomac winter road, used for the transportation of materials to and from the North Inca site, is provided on Figure 2.

5. Summary of Operations
a) Describe purpose, nature and location of all activities The remediation of the site is to be carried out in accordance with the North Inca Remedial Action Plan. The following general activities are planned: • Close the opening to the underground and fill in surface trench; • Regrade rock pile along the shoreline; • Demolish any remaining infrastructure and treat debris as required; and, • Collect and consolidate any waste and debris on site for removal.
Please see attached Appendix B of the land use application for a general description of remediation activities. More in-depth information and can be found in Section 1.2 of the North Inca Remedial Action Plan. No new roads on-site or infrastructure are proposed; some maintenance and upkeep of remediation measures is expected. Equipment and materials will be brought to the site via the Colomac winter road; a small spur road will be built to gain access to the site.
Note: the Appendix B referenced above was the Appendix B of the application. The remediation of the North Inca Site was carried out in accordance with PWGSC contract documentation. These documents were based on the Remedial Action Plan (RAP) for North Inca, which was submitted with the application. The primary purpose of the civil works activities over the duration of the land use permit was to remediate the mine site and ensure the protection of local and downstream environments.
The site work was completed between March 2009 and March 2010. The Contractor mobilized equipment and materials during the March 2009 winter season. The 2009 winter season included partial set-up of the camp, removal of the designated and hazardous materials and demolition of buildings and structures. The summer construction season ran from June 2009 to August 2009, with completion of the structure demolition, debris removal/stockpiling, contaminated soil removal/stockpiling, construction of the mine opening seal and re-grading earthworks. The final off-site
______5 Land Use Permits W2009X0002 Final Plan March, 2012
transportation and disposal of stockpiled materials and complete site demobilization was concluded during the March 2010 winter season.
One final activity that was completed in March 2011 was the removal of the D3 dozer that was found between the North Inca and the Diversified Mine Sites. The D3 was dragged over a pre-existing trail to the shoreline. It was loaded onto a truck and shipped by Winter Road to the Mine Heritage facility in Yellowknife, where it is currently on display. A small oil stain that had been identified under the D3 will be remediated as part of the remediation of the Diversified Mine Site.
March/April 2009 Winter Season TEES commenced site activities March 20th, 2009, basing their operation out of the Colomac Mine site camp. CJ Contracting, a subcontractor of TEES, cleared snow off the ice between the Colomac winter road and the site (for the spur road to the site) to permit access to the North Inca Mine site areas.
The 2009 winter work was completed between March 20th and April 9th, 2009. The activities carried out included: • Construction of a site access spur road off of the main Colomac winter road for the winter season work; • Snow removal; • Initial site survey; • Removal of designated substances and hazardous materials from the buildings; • Demolition of building structures and preparation of equipment for off-site transport; • Debris removal (e.g. steel bed debris from the camp site, small miscellaneous steel materials) from the mine site; • Burning of untreated wood debris; • Consolidation of empty drums; • Transportation of building debris to the Colomac Site; • Off-site transportation of heritage items to Yellowknife; • Transportation of asbestos-containing materials to Colomac site for disposal in the Spruce Lake Disposal Cell; • Off-site transportation of hazardous paint and equipment to a Hazardous Waste facility; • Transportation of empty drums to the Colomac Site; • Mobilization of summer work materials and equipment; and • Demobilization of equipment intended for only the winter program.
June/ July/ August 2009 Summer Season TEES mobilized their 2-person start-up crew and a 3-person Discovery Mining Services (DMS) crew to the North Inca site on June 22nd, 2009 to begin construction of the camp. The first TEES work crew and the PWGSC department representative were transported to the site on June 29th, 2009. All summer access to the site was via float plane. ______6 Land Use Permits W2009X0002 Final Plan March, 2012

b) Please indicate if a camp is set up A small temporary field camp will be set up to accommodate work crews during the remediation work. The contractor will determine what type of camp set up is required to support remediation efforts. Currently the best option for the camp would be on the east side of the peninsula with drinking water obtained from Indin Lake. Sewage wastes will be disposed of in a sump on site.
Domestic waste will be managed on site by a fuel fired EPA approved incinerator.
A shelter was erected during the March 2009 land use operations. This shelter contained a displayed copy of the LUP. DMS erected the temporary field camp between June 22nd and 29th, 2009. The camp was taken down and removed during the March 2010 demobilization.
The TEES field camp was located on the flat plateau level of the mine site area near the location of the former mine dry/hoist house locations; the sump was located at the back of the camp. The sump location was reviewed by DIAND Inspectors and written authorization provided July 3rd, 2009. Sewage from the pacto toilets was burnt daily and grey-water was disposed of in the sump. The land use area was kept clean at all times. Combustible camp garbage and debris were burnt daily in the camp incinerator.
Water for the camp was obtained from Indin Lake and the water intake was constructed with a screen. Water treatment was specified in the LUP by the Government of the Northwest Territories (GNWT) – Health. The contractor, TEES, tested the water from Indin Lake during the winter work program and confirmed that water quality met Health Canada (HC) Guidelines for Drinking Water Quality. Regular testing continued during the operation of the camp.
6. Summary of potential environmental and resource impacts (describe the effects of the proposed land use operation on land, water, flora and fauna and related socio-economic impacts).
Any impacts to the North Inca site will be positive. Please refer to the Remedial Action Plan (RAP) for a complete description of potential environmental and socio economic impacts from the project and prescribed mitigation measures.
Generally, impacts to the North Inca site were positive, with the removal of debris and environmental contaminants. Site work was completed in a manner which minimized effects on the land, water, flora and fauna. Plywood sheeting was used to support areas where there were signs of rutting due to All-Terrain Vehicle (ATV) use. Sediment and erosion controls, in the form of silt fences and floating turbidity curtains, were used for the work near the shoreline. ______16 Land Use Permits W2009X0002 Final Plan March, 2012
Interaction with the local fauna was avoided. For example, a bird nest was seen on the ground adjacent the access route to the Camp site. The area was sectioned off with warning tape to avoid disturbing the nest. Workers were made aware of the area. The GNWT-ENR Wildlife department was informed of the nest and saw no issue with working around the area.

7. Proposed Restoration Plan
This application is to authorize the remediation of the site. The site will be remediated to current acceptable measures which were agreed to by both the Government of Canada (through Indian and Northern Affairs) and through consultation with Tlicho representatives. As the project to be undertaken is such that will mean improvements to the site, any changes are assumed to be beneficial. All camp structures brought on to the site will be removed upon completion of the project and Land Use Permit. For the remediation details please Appendix B for a general overview and attached North Inca Remedial Action Plan.
Note: The Appendix B referred to in the above passage was the Appendix to the application. As the project was undertaken to remediate a former mine site, changes to the site have been beneficial. All camp structures brought on to the site were removed upon completion of the remediation project. The grey-water sump was backfilled and restored at the completion of site work. Land restoration was conducted as per Condition 26(1)(o) of the LUP, with all clean-up and restoration of the lands completed by the end of the remediation project.

8. Other rights, licenses or permits related to this permit application (mineral rights, timber permits, water licenses)
a) Other rights, licenses or permits
There are no existing rights, licenses or permits for this site.
A burn permit application will be submitted by the contractor to reduce brush and non-hazardous wooden materials.
Rights, licenses or permits for this site were not established between the time of the application and the completion of remediation. Burn permits were obtained by the contractor for all required burning to reduce brush and non-hazardous wooden materials.
Prior to the application for the permit, Pine Valley Mining Corporation (PVMC) held Mineral Claims and leases that included or were near the North Inca site. PVMC also obtained a Storage Authorization Approval (MV2003X0024) on December 19th, 2006 for storage of equipment on the nearby Diversified property. The Claims and leases were transferred to George Stephenson by PVMC on June 1st, 2007. On September 21st, 2007, Mr. Stephenson withdrew his application for the assignment of the PVMC Land Use Permit.
A land application (#86 B/6-7-1) for a reserve was filed with the Lands Administration Division of AANDC. The reserve includes the North Inca shaft cap, trench re-graded area and waste rock re-graded area. The area of the application is shown on Figure 12.
b) Roads- Is this to be a pioneered road? Has the route been laid out or ground-truthed?
No. A small spur road (approx 500m) will be built onto the winter road to Colomac in order to access the North Inca Site. Contingency and mitigation measures are formed under that contract. Existing roads are to be cleared and utilized as required.
Maps of the existing Colomac Winter road route can be found in Appendix D of the Land Use Permit Application.
Note: The Appendix D referred to in the above passage was the Appendix to the application. No new roads were developed under this permit; pre-existing roads or trails across the bedrock were utilized to access areas of the site. Brushing of the existing roads was completed in compliance with Condition 26(1)(n) (Methods and Techniques for Debris and Brush Disposal) of the Land Use Permit. A small spur road (approx 500m) was built from the winter road to Colomac in order to access the North Inca Site for mobilization and demobilization.

The Departmental representative (DR) monitored and reported on the use of equipment at the North Inca site. They reported that the equipment used for the work was listed in the application.
The majority of equipment used on the North Inca project was contractor supplied. The exception was limited use of the Crown Equipment from the Colomac Project during winter operations. This included use of a Colomac Tandem Truck, for transport of materials from North Inca to Colomac for disposal, a pick-up truck for use of site personnel, a truck and float for movement of major equipment and a payloader for movement of heavy loads, bags, etc. This equipment use occurred at a period of low equipment usage at the Colomac site, so the Colomac project was not affected.
Summary of Crown Assets Used at North Inca Description of Comments Crown Asset Tandem Truck Used February 15 – 28, 2010 – from Colomac Crown inventory. Returned to Colomac in good condition at the end of use. Used for transport of North Inca wastes from North Inca to the disposal areas at Colomac. As this equipment was already at the Colomac site, use of this equipment saved considerable mobilization costs without impacting the operations at Colomac. Pick-up Truck Used February 8 - 28, 2010 – from Colomac Crown inventory. Returned to Colomac in good condition at the end of use. The pick-up truck was used to transport personnel from Colomac to North Inca (North Inca personnel stayed at Colomac accommodations), as a weather haven while on the North Inca site, and for general transportation between North Inca and Colomac. . As this equipment was already at the Colomac site, use of this equipment saved considerable mobilization costs without impacting the operations at Colomac.

Description of Comments Crown Asset Truck and Used February 15 - 28, 2010 – from Colomac Crown inventory. Returned to Colomac in float good condition at the end of use. This equipment was used for staging other heavy equipment, both Crown and contractor owned, between North Inca and Colomac. It was also used in conjunction with the Tandem Truck to transport materials from North Inca to Colomac for disposal. As this equipment was already at the Colomac site, use of this equipment saved considerable mobilization costs without impacting the operations at Colomac. Loader Used February 15 - 28, 2010 – from Colomac Crown inventory. Returned to Colomac in good condition at the end of use. The loader was used for loading material into the Tandem Truck and onto the float for transport to Colomac for disposal. Some general scraping and clean-up was also completed with this equipment. As this equipment was already at the Colomac site, use of this equipment saved considerable mobilization costs without impacting the operations at Colomac.
11. Fuels
11. Fuels () Number of Capacity of containers Location containers Diesel x 1 100,000 Litres (~60,000 North Inca litres to be brought in to Site site) Gasoline x 4 45 gal drums North Inca Site Aviation fuel Propane x 1 100 lb unit North Inca Site Other
The work fuel storage containers were placed at the interior edge (farthest edge from Lake) of the mine site area. CARD notified WLWB and the DIAND Resource Management Officer (Clint Ambrose) of the inability to achieve the 100 metre set back from the ordinary high water mark of Indin Lake for the fuel storage. The Inspector provided written confirmation that DIAND-CARD was authorized to store fuel 30 metres from the ordinary high water mark of Indin Lake, with the condition that secondary containment (i.e. drip trays) be implemented for fuel transfer locations and under fuel drums used for fuel supply to heater units for tents in the camp.
All container outlets were sealed, except the outlet in use. Spill kits were available on site and secondary containment was in place under fuel drums. The diesel fuel storage tanks were a 4,500 litre (L) horizontal double walled tank and a 9000-L vertical double walled tank. Additional gasoline and diesel was stored on-site in 45 gallon drums. Secondary containment was placed under all transfer nozzles, valves, etc. Five 100 pound propane tanks were also kept on-site. Aviation fuel was not stored on site as planes re-fuelled at Colomac. No fuel spills were reported.

12. Containment fuel spill contingency plans
A draft Spill Contingency Plan, with MSDS sheets, is included with the application in Appendix C. The successful contractor will be asked to prepare a Spill Contingency Plan that meets or exceeds the requirements of this plan. The plan must be submitted to INAC before any work occurs on site. This plan will be forwarded to the Wek'eezhii Land and Water Board and Inspectors before any site activities occur.
Spill kits will be available on site and secondary containment will be in place under the fuel drums that are supplying the pumps. All tanks will be double walled green tanks. Secondary containment will be placed under all transfer nozzles, valves, etc.
Note: Aviation fuel will not be stored on site - any planes requiring fuel will go to Colomac for re-fueling.
The Contingency Plan and Reporting Practices for Oil and Hazardous Material Spill (TEES, 2009) was submitted to the DIAND South MacKenzie District Office on June 30th, 2009. The contingency plan and spill kits were in place during all remediation work to respond to any potential spills.
13. Method of fuel transfer (to other tanks, vehicles etc)
Electric Pump, API certified hose, couplings, sliptanks on flatbed or trailer.
Fuel was transferred to on-site equipment using dispensers and electric pumps, in accordance with fuel management standard operating procedures. API certified hose, couplings, and slip-tanks on flatbed or trailer were also used.
14. Period of operation (includes time to cover all phases of project work applied for, including restoration)
It is anticipated that equipment and materials will be mobilized to the site in March 2009. The remediation work will take place during the summer of 2009 with equipment and materials demobilized on the 2010 winter road.
Work on the North Inca Remediation was completed in three phases. The 2009 winter program was completed between March 20th and April 9th, 2009. The 2009 summer program extended from June 22nd, 2009 to August 13th, 2009. The 2010 winter program was completed between March 8th, 2010 and March 29th, 2010. The D3 Dozer was removed from the North Inca site in February 2011, and taken to the Mine Heritage Society in Yellowknife. Arrangements have been made for recovery of hydrocarbon ______22 Land Use Permits W2009X0002 Final Plan March, 2012
impacted soil from a leak under the D3. The soil will be manually excavated and treated with hydrocarbon impacted soils from the Diversified Mine site.
No further land operations are anticipated at the North Inca site.
15. Period of permit (up to 5 years with a maximum of 2 years extension)
2 years
Land Use Permit MV2009X0002 was granted for a period of 5 years, and expires March 18th, 2014.
V LAND USE
Over the duration of this land use permit, a number of land use activities were undertaken. Waste consolidation and impacted soil remediation was completed. The site was already negatively impacted by the previous mine development, so the activities under this permits were in support of overall site remediation and improvement.
In accordance with Section 33 of the Territorial Land Use Regulations, the following plans are provided: a) Lands subjected to the land use operation; b) Lines, trails and cleared areas used during land use operations; and c) Excavations and other works and places.
Also provided in this section is a calculation of the territorial lands used in this operation and an aerial photograph showing the lands subject to the land use operation.
