Why geothermal in Fort Liard ? Good Geology Oil & Gas Wells Drilled in the Ft. Liard Area Hot sedimentary aquifer (HSA) versus volcanic system Good Data > 30 deep wells in the area, significant risk reduction ~5km away, 1 well to 4,579m (deeper than our target zone) ADKFN Land Claims Area Great Hosts ADKFN has the capacity to participate, capability to manage, and a genuine interest in developing the project
Our Target: Fort Liard’s power requirements Comparative Load information Current generation provides: 4,160V, 3 phase power at 60 Hz Historic peak demand: 540 kW Capacity (2006), current 523 kW Current consumption ~2.8 – 2.9 Million kWh’s (61.5% load factor) No daily measurement – so used Wha Ti and Tulita as proxies Used ‘worst case’ scenario for design – summer peak, maximal load increase
We propose to develop a HSA geothermal project for supplying Fort Liard’s power Project Schematic: Overview At site, Nahanni is ~4,250m deep, implying 170 C brine at Power OUT Heat OUT 0.6 MW NET 6.8 MW GROSS surface T IN T OUT 170 °C 109°C Binary technology employed to Binary Unit extract power NTPC’s existing diesel units as backup Injector Mattson 750m 1,500m Option for Phase II heat 27 project(s) off the rejected heat Kg/s (max) from the binary fluid Brownfield location: Beaver Producer Enterprises “Base camp” Nahanni 150m 4,250m
At the site, we intend to drill 2 wells and build a permanent power facility (A) Plant Site: Overview Land Ownership: Overview Drill Pad Plant Site

The subsurface Production target is the Nahanni formation Estimated Depths and Lithologies At site, Nahanni is ~4,250m deep and ~150m thick Permeability Porosity Existence of water and water quality ‘Bottom Hole’ Temperature ‘Bottom Hole’ Pressure
The Production well requires some pumping to bring the brine to surface Production Well Design Fully cased hole Casing diameters from 406mm to 178mm Groundwater protected by cemented casing and production tubing Lineshaft pump at ~ 200m Anticorrosion bleed below pump Specialty steel
The subsurface Injection target is the Mattson formation Estimated Depths and Lithologies At site, Nahanni is ~1,500m deep and ~750m thick Permeability Porosity ‘Bottom Hole’ Pressure Shale cap
The Injection well disperses the brine over a large open hole area Injection Well Design Fully cased hole to 750m Groundwater protected by cemented casing and production tubing Slotted liner supporting formation in re-injection zone (~750m) Specialty steel

In a later Phase II, there will likely be one or more direct heat projects 6.8 MW Gross @ ~ 70 °C (Binary) + large heat @ 109 °C (Primary) Even utilizing only 1.0 MW would be sufficient heat for ~140 homes or a large commercial operation The binary heat is effectively free and using a ‘heat sink’ will reduce air cooling loads and increase overall power production Common applications Household heat Green House and Fish Farming Drying (lumber, pellets, crop) Water systems, et al
The project schedule has significant slack built into it Drill, test, and complete wells – Summer/Fall 2012 Order long lead items – post-test in Summer 2012 Clear final site – Winter 2012/2013 Construction – 60 days – Summer 2013 Commissioning – 30 days – Fall 2013 Conservative online date – January 1, 2014
The economic benefits are overwhelming Net investment to GNWT = ~7.3 MM Versus diesel, but using diesel as backup, NPV >$30MM in cost savings Reduced commodity price volatility Build capacity to extend geothermal to other applicable communities in the North (power and direct heat)
Further, there are significant social benefits GHG reduction in Fort Liard Noise Reduction in Fort Liard First Nation ownership stake = long term income stream One time construction jobs Long term jobs available with Phase II direct heat applications Creation of a regulatory environment recognizing geothermal power/heat = future projects
Response to Environment Canada Broadly speaking, Borealis is prepared to accept the 19 EC recommendations as posed Recommendations and Comment: #7 Review of E2: Borealis/EC discussion regarding incremental reporting requirements #14 Migratory Birds: Continued open dialogue with EC on appropriate pro-active measures which would negate the interest of migratory birds for nesting in the area
Response to AANDC Broadly speaking, Borealis is prepared to accept the 23 AANDC recommendations as posed, with exceptions Recommendations and Comment #7: Worst case scenario for spills of primary fluid from drilling and operations: Borealis supports the original calculation provided on March 7 th , 2012 at technical hearing #8: Specific spill response: Borealis supports that a Spill Response, and specifically the training provided to on site personnel, needs to be flexible enough to handle a wide variety of contingencies while providing sufficient information to inform positive decision making #11 & 12 Groundwater: Borealis believes that committing to follow the direction on the National Energy Board and Alberta Energy Resource Conservation Board design, installation, and monitoring requirements, as requested in AANDC’s recommendation #14, is more than sufficient to protect local groundwater #14: Water monitoring of fluids: Borealis suggests that, for the first year, monthly samples be taken for analysis. Further, that after the first year of operation, samples need only be taken every 3-6 months.
Response to E&NR Worked with Environment and Natural Resources To better understand and directly address any concerns they have over our handling of any H 2 S emissions and/or hazardous waste Agreement on highly conservative H 2 S release rate associated with drilling and completion/servicing Agreed to expand our description of handling H2S emissions during drilling and operations Thank you! for working with Borealis & ADK to help to move this innovative renewable project forward in the NWT.
