4 Earthworks & Site Development Photos: NUNA Remote Mine Site Development Proper classification of Canada s permafrost is essential to mine planning, development and operation to ensure the location of mine infrastructure will have the least impact on permafrost. NUNA s combined management and site personnel have worked throughout Canada s North gaining a high level of experience with varying permafrost. Additionally, NUNA has the earthmoving fleet capacity to address the movement and placement of millions of cubic meters of earth required for mine site development. Successful Projects by NUNA & Partners AGnico-eaGle MINES LIMITED Meadowbank Gold, Nunavut, Canada NUNA s work primarily comprised the construction of an 108 km all-weather road starting north of the Hamlet of Baker Lake to the Meadowbank site. Nuna planned and mobilized all equipment and supplies to Baker Lake necessary for year-round construction activities with only 6 weeks to source and position at Churchill, Manitoba for furtherance by barge to Baker Lake. Road construction required the planning and development of 22 quarry locations, crusher operation, drill and blast activities, survey control for layout and as-built preparation as well as installation of 9 bridges to facilitate the river crossings and 119 culvert installations. NUNA also carried out the construction and maintenance of all necessary infrastructure to support the operation. newmont MINING CORPORATION (Formerly Miramar Mining Corporation) Hope Bay Gold Project (Doris North), Nunavut, Canada Since 1991 Nuna has worked closely with Miramar Mining (former owner) with respect to project planning, design and costing estimates. Nuna continues that process under Hope Bay s new owners, Newmont Mining. In 2007, Nuna mobilized, via barge, equipment, supplies and a crew of 37 into site and provided site services, construction of the Windy Lake 2,800' airstrip, camp pad, tote road, crushing and construction and maintenance of seasonal ice access roads (Roberts Bay to the Doris North site). In 2010, Nuna became General Contractor, as well as part of the EPC Design-Build Team, to optimize design and minimize total installed costs. NUNA provides a full complement of services including safety, engineering, quality control and procurement and are involved in all planning, scheduling and execution of site civil infrastructures: roads, airstrips, jetty landings, quarry development, culvert and bridge installations, and site services support.

5 Dependable Project Development Committed to Northern Development Dams & Dikes Photo: NUNA NUna provides efficient and cost-effective dam and dike construction services. Structurally and environmentally sound, frozen core dams provide an efficient and reliable control of tailings and other effluents in challenging environmental conditions.

6 Dams & Dikes Photos: (l-r) J. Herman, J. Herman, Diavik Frozen Core Dams Frozen core dams are a type of earth filled dam typically constructed in high latitudes with permafrost conditions. Coolant circulates through thermosyhons to maintain a water-tight region of the permafrost within. NUNA has designed and assembled its own plants for the construction of frozen core dams. The plants can accurately monitor the moisture content and temperature of core granular material prior to placement and produce up to 4,000 tonnes per 24-hour shift. Bhp Billiton DiamonDS Inc. EKati Diamond Mine, Northwest Territories, Canada NUNA has been involved as a contractor with BHP from the early stages of devel op ment of its $1 billion EKATI Diamond Mine. One challenge for the EKATI Mine was to build an 800 m long frozen core dam to contain 100 million m 3 of processed kimberlite in an area where there was no source of low permeable soil and a number of other soils constraints such as sand, gravel, boulders, permafrost and an unfrozen zone below the boulder creek bed. The solution EBA Engineering designed and NUNA constructed the award-winning Leslie Long Lake Frozen Core Dam with a core created of saturated, processed sand and gravel placed in layers during the winter so that each layer froze before subsequent material was added. Thermosyphons, which are passive devices, were installed to keep the structure and the otherwise permeable creek bed frozen. The success of this dam resulted in 3 other similar dams at EKATI s satellite site, Misery, which NUNA constructed. Dikes Dikes serve to isolate portions of lake beds from the main lake body providing accessibility for open pit mining. Rio Tinto, Diavik Diamond Mines inc. Diavik Diamond Mine, Northwest Territories, Canada Lac de Gras Constructors (LDGC) is a joint venture between NUNA and Peter Kiewit Sons, formed to construct Diavik Diamond Mines A154 dike, North Inlet dike, A418 dike, and raising of the PKC dams. LDGC s A154 and A418 dike contract comprised dike construction, dewatering and pre-stripping. The A154 dike is the first dike of its kind constructed in Canada and was completed ahead of schedule. The A154 kimberlite pipe, located 20 m below water off an island in Lac de Gras, required the construction of a 3.9 km long and up to 25 m high dike to enclose an area of 1.5 km 2. Construction of the dike involved placing 2.2 million m 3 of zoned rock fill and a plastic concrete diaphragm wall which extended through both the fill and the till foundation. The wall was joined to the granite bedrock by a continuous barrier of jet-grouted columns. A418 s water retaining dike and cut-off wall is 1.2 km long, required approximately 1.1 million cubic meters of rockfill and was built in water up to 32 m deep. A418 dike joins the existing A154 dike with construction methods similar to A154 various sizes of rockfill, a central plastic concrete cut-off wall, jet and curtain grouting and installation of instrumentation. A significant crushing facility prepared much of the rock obtained from A154 open pit.

10 Ice Roads & Airstrips Photos: NUNA Ice Roads & Airstrips NUNA has constructed the majority of Nunavut s and the Northwest Territories exploration and early-mine operation access ice roads and Hercules aircraft capable ice airstrips. For Canada s remote north, ice roads and airstrips are critical supply links. In particular, the regional mining industry depends heavily on the Tibbitt to Contwoyto Winter Road for the transportation of construction equipment, building materials, equipment parts, oil and essential survival goods such as food and fuel for power generation. Successful Projects by NUNA & Partners Tibbitt to Contwoyto Winter Road Joint Venture The Tibbitt to Contwoyto Winter Road (TCWR) has developed from an 800 load per annum road system to a renowned and engineered ice super highway with transport trucks delivering up to 10,000 loads during the months of February and March each season. Since 1998, NUNA has constructed, maintained and dispatched the TCWR (formerly Lupin Winter Road). Camps, shops, laydown areas and fuel storage have been strategically positioned along the route enabling NUNA to respond quickly to various demands placed on operating a heavy haul ice road in Canada s remote and harsh north. The TCWR starts 70 km north of Yellowknife, Northwest Territories, traverses between 400 km and 600 km (depending on mining activities) and 85% frozen lakes and 15% land portages at its longest length. In earlier years, the route terminated at Echo Bay s Lupin Gold Mine and then was extended to reach Tahera s Jericho Diamond Mine. With both of these mines in care and maintenance status, the TCWR now terminates near the Diavik Diamond Mine.

11 Committed to Northern Development Dependable Project Development Mine Reclamation Care & Maintenance Photo: NUNA Nuna s experience in reclamation, care and maintenance is born out of its involvement in many of the major Canadian arctic mine developments and exploration programs.

12 Mine Reclamation Care & Maintenance Photos: NUNA 100+ years of experience NUNA s management team and northern operation personnel have a combined years of experience in the design and execution of remote arctic mining developments and reclamation projects such as the reclamation activities of Port Radium and Pine Point, located in the Northwest Territories. NUNA understands and adheres to the strict environmental regulations that govern reclamation of mine sites including: handling of hazardous materials (hydrocarbon contaminated soils, reagents) tailings, reclamation and site rehabilitation. NUNA s site specific procedures are based on our Integrated Health, Safety and Environment Management System (IHSEMS). NUNA establishes and implements hazardous materials handling and disposal programs at all NUNA work sites. Successful Projects by NUNA & Partners Public WorKS Government Services Canada Giant Mine, Yellowknife, Northwest Territories, Canada In 2004, NUNA, through a joint venture with the Deton Cho Corporation, was contracted by Public Works Government Services Canada to provide care and maintenance at the Giant Mine site. The site carries pre-existing environmental conditions including 237,000 tonnes of arsenic trioxide stored underground. NUNA s services at Giant Mine cover a wide range including maintaining site facilities and equipment, underground access and hoisting and pumping equipment, site security, pipework upgrade and demolition of bulk fuel storage and selected buildings. NUNA reconstructed the nearby Baker Creek, specifically the rehabilitation of the existing channel over a linear distance of 600 m (1,969'), creation of a new stream channel and construction of a 21 m (70') clear span steel bridge to support future heavy equipment traffic. Giant Mine Freeze Optimization Study Under the Giant Mine care and maintenance contract, Deton Cho/ Nuna Joint Venture provided construction services to support a trial project designed to optimize methods of freezing the underground arsenic storage chambers. Our work included surface drilling by a variety of methods (mud rotary, coring and down hole hammer) and installation of piping for a mechanical freezing system, instrumentation installations, underground development required for horizontal drilling and freeze pipe installation, surface civil works and site grading and bulkhead construction.

13 Committed to Northern Development Dependable Project Development Large Diameter Drilling Photo: Shore Gold Inc. Nuna Drilling provides large diameter drilling using the Bauer BG 36, a state of the art drill rig capable of augering to a depth of 85 m and flooded reverse circulation drilling (1,200 mm diameter) to an ultimate depth of over 350 m.

14 Large Diameter Drilling Photos: NUNA Nuna Drilling Services NUNA Drilling s Bauer BG 36 drill rig systems are capable of drilling 1,200 mm (4') diameter holes to a depth of 350 m (1,150'). These diesel-powered electric/hydraulic units utilize Caterpillar-powered crawler units with retractable masts. After a unit is walked to a large diameter drill (LDD) location, overburden to a maximum depth of 85 m (279') is augered using a Kelly system with a selection of excavation tools. A Bauer-supplied oscillator is used to set and recover double-walled casing to as much as 40 m (131') depth. Beyond that depth, or in harder formations, the system is reconfigured to use reverse circulation drilling. In reverse circulation mode, 6 m (20') long sections of 9-5/8" double-walled drill pipe are added to the drill string utilizing a manipulator which enables an operator to handle pipe while safely removed from the suspended load. Compressed air is supplied down the hole between the inner and outer pipe walls. Air valves which form part of the drill string allow high-pressure air to enter the inner pipe at a distance above the hole bottom and to escape to surface; the vacuum created lifts slurry from the hole bottom. Holes are drilled in flooded conditions utilizing drilling muds to stabilize open holes below the casing. A variety of drill bits are employed to suit conditions which range from soft soils to rock with high compressive strengths. Drill data is electronically recorded for later analysis. Sampling for diamonds in kimberlite is accomplished through the use of a desanding unit which separates drilling fluids from the sample, washes the sample and recovers materials greater than a specified size. The samples are bagged and transported to a designated area. Drilling operations are 24 hours per day, year-round. Successful Projects by NUNA & Partners Shore Gold Inc. Star Diamond Project, Prince Albert, Saskatchewan, Canada Bulk Sample 184 Holes (39,000 m) (128,000') Shore Gold Inc. s Star Diamond Project lies in Fort à la Corne, Saskatchewan, hosting one of the most extensive kimberlite fields in the world. The kimberlite is overlain by as much as 120 m (394') of overburden consisting of sand, mudstone, boulders and glacial till. NUNA Drilling was chosen to conduct a large diameter drill program, with an initial target of 72 holes, to collect bulk samples from the extensive area. Holes were 1,200 mm in diameter (4') with depths ranging to over 300 m (984'). Working with Bauer Maschinen GmbH, NUNA Drilling developed new equipment and techniques to drill holes in 2 stages. The process used 2 sets of fully-equipped mobile BG 36 drill rigs, bentonite and polymer solutions and primary support equipment; all provided by NUNA Drilling. Holes were Kelly drilled through the first 85 m of overburden and then the rigs were switched to reverse circulation drilling and geologists were provided sampling intervals. Rigs were walked between holes and the skid-mounted support equipment was repositioned with support equipment. Operations continued year-round on a 24 hour basis. NUNA Drillings work for Shore Gold extended onto the FALC Joint Venture ground where a series of similar holes were drilled. Accumulated drill program covered 184 holes (39,000 m) (128,000').

15 Committed to Northern Development Dependable Project Development Heavy Equipment Contract Training Photo: NUNA NUna TRAINING TECHNOLOGieS delivers to your doorstep professional, cost effective and comprehensive heavy equipment operator/instructor training and safety programs. NUna utilizes classroom, simulator and field training methodologies meeting legislative and industry best practices.

16 Heavy Equipment Contract Training Photos: NUNA Quality & Value NUNA provides heavy equipment training and safety programs to Canada s mining and construction industries, government and educational institutions. The foundation of our training is based on years of experience gained as equipment operators, safety facilitators and as mining and construction contractors. NUNA s instructors understand that people learn by different means and that Canada comprises various cultures and environments and have developed training programs accordingly. Companies that employ heavy equipment understand that proper equipment training protects people and assets. Training can represent a significant amount of the operating budget. The fixed costs of lost equipment productivity revenue, fuels and lubes, and the wear and tear a machine might receive in the initial training process are all good reasons to look for a better way. NUna s heavy equipment simulator training is value adding by lower costs and risk to employees and equipment. Field & Simulator Contract Training custom designed specific to training those who desire to work in the mining and construction industry while meeting the needs of mining and construction operations. Simulator Based Training Programs Haul Truck, Wheel Loader, Crawler, Dozer, Track Excavator, Motor Grader Combination Program Simulator and Field Field Based Training Programs (including valuable classroom sessions), Skid Steer Loader, Forklift, Compact Equipment, Motor Grader, Flag Person, Diamond Drill Helper, NUNA s mobile heavy equipment simulators offer a safer, faster and more economical means to test, train and retrain frontline equipment operators and instructors. Designed to meet various operator levels, training programs can be customized to meet the unique requirements of a wide range of mining and construction operations. Within the simulator, the operator sees, hears and feels everything in a realistic way just as if they were operating the actual heavy equipment. Instruction in practical terms on how to react to brake failures, tire fires, wet and slippery conditions, fog and dust and night driving are just a few examples of this simulated reality training. NUNA s simulator provides the trainers with selectable lesson levels that record the operator s performance and the machine s operation from start-up to shut-down. This important feature ensures unbiased evaluation. A new or pre-employment operator is exposed to all simulator lessons and error warnings, while experienced operators undergo refresher testing without assistance from the simulator trainer. Lessons make use of advanced multimedia including voice-over narration and graphics (in both English and local dialects) to get the correct method and message across. NUNA supplements this training with classroom video, manuals, study material and examination. The simulator s inter changeable vehicle, site and dash components provide complete flexible training on a wide range of equipment types, such as the full line of Caterpillar haul trucks, excavators and shovels; and Bell, Komatsu and Hitachi dozers, loaders, rope shovels and underground machinery. The simulator can be up and running within hours of arrival at a mine/construction site, and is so cost-effective that companies can recover training costs with the saving on fuels and lubes alone.
