CANADA NORTH FIBRE LOOP PROPOSED GEOTECHNICAL & GEOPHYSICAL PROGRAM OVERVIEW MACKENZIE AND PEEL RIVER CROSSINGS FEASIBILITY STUDIES REVISION 0006 AUGUST 2 2016

PROJECT INTRODUCTION The Canada North Fibre Loop (CNFL) is a Northwestel (NWTel) driven project  to complete a fibre loop between 26 terrestrial Northern communities in the Yukon and the Northwest Territories. This loop will be accomplished by running a 775 km length of fibre cable  along the Dempster Highway from Dawson City, YT to Inuvik, NT and joining up with the Mackenzie Valley fibre line currently under construction. Presentation includes 2 main portions:  Description of fibre redundancy  Description of scope of work for geotechnical and geophysical studies  Phase 1 of this project is to finalise the design and cost.  Phase 1 includes desk top assessments, GIS work and some field work.  As recommended by the Gwich'in Land and Water Board, we are reaching out  to all stakeholders and First Nations to discuss the project and the requirement for this small drilling program in particular. 2

FIBRE REDUNDANCY • Current situation results in service disruptions for Northern communities • Solution requires significant investment in fibre infrastructure Northwestel seeking to implement self-healing fibre rings to protect services for communities in the Yukon and Northwest Territories 3

FIBRE WITH NO DIVERSITY (CURRENT STATE) • If fibre is damaged due to events such as a forest fire or a contractor who cut the line while doing work along the road – then service between communities 1 and 2, and then communities 2, 3 and 4, is disrupted. • Depending on location of damaged cable, it can take from 6 to 12 hours to mobilize resources to repair the cable, travel to the site, complete repairs & restore service. • As businesses increasingly rely on the Internet to operate – whether for point-of-sale equipment, inventory management, purchasing, airline passenger check-in or a host of other applications – any service outage can result in forced shut-downs and/or closures until service is restored. Fibre damage can have significant impact on the economy & community 4

SELF HEALING FIBRE LOOP (FUTURE STATE) • A fibre loop (or ring) can be compared to an oval racetrack: there are 2 ways around the track and if you start in one direction and encounter an obstruction, you can simply turn and go the other way around the track to get to the other locations. • With a ring, if the control equipment senses a disruption in the data travelling in one direction, it simply re-routes traffic in the other direction so that communities remain fully connected. Fibre rings are automatically self healing, maximizing network reliability, ensuring no loss of service for customers 5

CANADA NORTH FIBRE LOOP • Canada North Fibre Loop would connect fibre in the Yukon with the MVFL in the Northwest Territories, creating full redundancy in the two Territories • Requires placing approximately 775km of fibre from Dawson City (YK) to Inuvik (NWT) • Benefits of this project – once complete, this self-healing fibre loop will provide robust protection against fibre cuts in: - Yukon, Northern BC and along the Mackenzie Valley in the NWT (26 communities) - Cellular and Internet in the satellite served communities in the North (36 communities) • In preparation for this link, Northwestel will complete the extension of the existing fibre from Stewart Crossing to Dawson City in 2016 Building a more connected North 7

CANADA NORTH FIBRE LOOP STATUS Yukon Government has endorsed the Canada North Fibre Loop as best solution for redundancy  Northwest Territories Government is supportive of this project  Nunavut Government supportive  High level cost estimates range significantly today, and phase 1 is to provide a more accurate estimate and  provide the project timing required to construct the fibre route, this information is needed to facilitate the approvals and funding needed to undertake the project Proposed geo-technical work is important to clarify costs of boring under two major rivers in the NWT  9

PHASE 1 - STATUS Initial planning stage:  Preliminary river crossing investigations  Route review  Construction methodology review  Stakeholder engagement  Desktop assessment of cultural, environmental and wildlife sensitivities  Geotechnical and geophysical investigations:  Current plan is to complete geotechnical and geophysical investigations at the Mackenzie  and Peel River crossings Purpose is to understand subsurface details at existing ferry/ice bridge crossings in order to  determine cost and feasibility of crossing with a large horizontal directional drill (HDD) Type A Land Use Permit required for investigations  NWTel and Ledcor Technical Services (LTS) will commence engagement with intent to  apply for the Type A Land Use Permit under the Gwich’in Land and Water Board (GLWB) 10

PROJECT TEAMS Northwestel Ledcor Technical Services   John-Eric Petersson Jordan Woodall   Kluane Adamek Cheryl Katnick   Don Pumphrey Dan Commons   Paladin Crossings has been contracted to plan large HDD crossings and will be managing the geotechnical and geophysical investigations. 11

PROGRAM OVERVIEW Goal is to determine the subsurface profile of sediments and rocks  Cannot estimate cost and effort of the large drills without knowledge of the  underlying structure Drill will occur within DoT Right of Way next to existing ferry terminals  Highway or Ferry traffic will not be affected during drilling operations  Crew to stay in Tsiigehtchic & Fort McPherson and travel to and from site  Hours of work to be between 7 am and 7 pm  14

PROGRAM OVERVIEW Geotechnical Investigation  1 bore drilled on either side of rivers (Mackenzie 90m, Peel 65m deep)  20 m x 25 m work space per bore  3-person crew, up to 15 days to complete all four drills  Geophysical Investigation  Electrical resistivity (ERT)  Bathymetry survey  Ground penetrating radar (GPR)  3-person crew, 5 days to complete at both sites  15
