Along with its introduction and operations update, this report includes information on our work in the areas of economic prosperity, training, social well-being, and health, safety, and environment. In all we do, every member of our team of over 1,100 people strives to work safely, to ensure the safety of their co-workers, and to bring safety home to their families and their communities. In terms of operations, 2015 was a challenging year for Diavik. We, like producers of other commodities, saw a significant decline in the pricing of our product. Fortunately, the work done by our team over the previous several years, positioned Diavik to remain profitable during market volatility and downward pricing. But, it was also a year of successes. Our A21 construction team kept the expansion project on schedule and on budget. Development of the A21 ore body represents a major expansion for us. Our team is managing this US $350 million project and adding to our sustainability. And, unlike many in the resource sector, we’re hiring, thanks to this project. In terms of our work to protect the environment, our water licence was renewed, which was a major accomplishment. As well, our environment team received national recognitions for wildlife and waste rock research. Our partnerships with local communities remain strong. Through our community contributions, we continue our support for northerners and for local organizations whose vision, like ours, is a stronger, healthier north. I am very proud of the donations and sponsorships we make and equally proud of the donations generated by employee-driven initiatives. We also recognize the value of education as the building block for strong communities, and last year, our cumulative contribution to scholarships surpassed $3 million. Time and again Diavik is proving itself as a leader in sustainable development. To learn more, I encourage you to review the pages that follow, and connect with us through Facebook and Twitter. Above all, thanks to every member of our team for ensuring we operate safely, efficiently, and respectfully. Besides A21, our geology team added to our reserves, and in so doing, we can aim for consistent production past 2023. This is excellent news for all our team, and indeed for Marc Cameron all our partners, including communities, businesses, and President and Chief Operating Officer governments. The Diavik Foxfire – our largest gem-quality rough diamond ever – was also an exciting discovery, in 2015. Diavik Diamond Mines (2012) Inc. 02 Through a responsible approach to mineral development, we ensure we maintain our licence to operate. This also creates the opportunity to plan, implement, and deliver sustainable contributions to social well-being, environmental stewardship, and economic prosperity, within strong governance systems. By continually engaging with communities, governments, employees, customers, and businesses, we continue to ensure our business is safe, healthy, and strong. Rio Tinto Rio Tinto is a leading global mining group that focuses on finding, mining, and processing the Earth’s mineral resources. Supporting world-class assets is a world-class workforce of 55,000 people working in over 40 countries. Their safety is always the first concern.

Introduction At Diavik, sustainable development is integrated into everything we do. Our operations provide benefits and opportunities for local communities, businesses, and governments. We work with all our stakeholders to deliver substantial and lasting benefits. Proud of our legacy to the North Sustainable development Businesses include open-pit and underground mines, mills, refineries, smelters and power stations, research and service facilities, railways, ports, and ships. Major products are aluminium, copper, diamonds, gold, industrial minerals (borates, titanium dioxide, and salt), iron ore, thermal and metallurgical coal, and uranium. For more than 140 years, Rio Tinto has been unlocking the wealth held in the Earth’s mineral resources. Some of its mines have been in operation and generating value for more than a century. Our vision is to be a company that is admired and respected for delivering superior value, as the industry’s most trusted partner. We work with local communities to create benefits. As a global resource industry leader, we are always looking for new answers to the complex global and local challenges, including resource scarcity, climate change, community employment, and regional economic development. 03 Introduction Proud of our legacy to the North Dominion Diamond Corporation Dominion Diamond Corporation is the world’s third largest producer of rough diamonds by value and is listed on both the Toronto and New York stock exchanges. Both of its production assets are located in the low political risk environment of the Northwest Territories in Canada where the company also has its head office. Dominion operates the Ekati Diamond Mine, through its 88.9 per cent ownership, as well as a 65.3 per cent ownership in the surrounding areas containing additional reserves and resources, and also owns 40 per cent of the Diavik Diamond Mine. Between the two mining operations, diamonds are currently produced from a number of separate kimberlite pipes, providing a diversity of diamond supply as well as reduced operational risk. It supplies premium rough diamond assortments to the global market through its sorting and selling operations in Canada, Belgium, and India. The company maximizes the sales value of its rough stones from the Ekati and Diavik mines, and maintains a preferred position as a supplier of rough diamonds to the world’s diamond manufacturers (cutters and polishers) by dealing directly with them and tailoring rough diamond parcels to the client’s particular needs. Rio Tinto Diamonds Through its 60 per cent of the Diavik mine and 100 per cent of the Argyle mine, Rio Tinto Diamonds is one of the world’s major diamond producers. Rio Tinto Diamonds’ share of the production from these mines are sorted and prepared for sale at its sales and marketing headquarters in Antwerp, Belgium. Rio Tinto Diamonds’ sales and marketing group aims to differentiate itself by: • Providing the right customer with the right assortment of diamonds; • Tailoring its approach to serve each customer; • Creating long-term, mutually beneficial business relationships; and • Retaining the flexibility to respond to market opportunities. It maintains an extensive industry intelligence network and a high level of customer and product support, and also believes in supporting consumer confidence in its diamonds and plays an active role in addressing key industry issues around product integrity and sustainable development. Rio Tinto Diamonds is a founding member of the Responsible Jewellery Council. Established in 2005, the council is a notfor-profit industry organization with a mandate to promote responsible, ethical, social, and environmental practices throughout the diamond and gold jewellery supply chain from mine to retail. Additionally, Rio Tinto Diamonds has taken an active leadership role in the World Diamond Council, which represents the diamond industry in the Kimberley process. 04 More recently, Rio Tinto Diamonds has partnered with the Diamond Empowerment Fund – an international not-forprofit organization supporting education initiatives in diamond producing countries – on a number of programs aimed at raising awareness of the positive impact diamonds have around the world in the communities in which they are mined. Introduction Proud of our legacy to the North Diavik’s northern commitments Diavik Diamond Mines (2012) Inc., located in Yellowknife, Northwest Territories, Canada, is committed to ensuring local communities benefit from the sustainable development of its mine. Commitments are formalized through individual participation agreements with the Tlicho Government, the Yellowknives Dene First Nation, the North Slave Metis Alliance, the Kitikmeot Inuit Association, and the Lutsel K’e Dene First Nation. Diavik also has a socio-economic monitoring agreement with the Government of the Northwest Territories, which was signed by Aboriginal partners. Regulatory requirements and an environmental agreement between Diavik, Aboriginal partners, and federal and territorial governments formalize Diavik’s environmental protection commitment. The Environmental Monitoring Advisory Board, created under the environmental agreement and the socio-economic monitoring agreement, allow communities and governments to monitor Diavik’s environmental commitments. 05 Proud of our legacy to the North NORTH Wind Farm Waste Transfer Area A21 Access Road Coronation Gulf A21 Location Umingmaktok Kugluktuk Coppermine River Arctic Circle Satellite image 23 August 2014 Diavik at a glance • A21 kimberlite ore body development on schedule and on budget • Four ore bodies – A21, A154 South, A154 North, and A418 • Spending (2000 to 2015) – C $6.8 billion ($4.9 billion northern, of which $2.5 billion was Aboriginal) • Operations workforce (31 December 2015) – 1,134 (546 northern) • Total mine life – 16 to 22 years (currently in year 14) • 2015 rough diamond production – 6.4 million carats • Reserves – 18.7 million tonnes NORT TERR HWEST ITORIE Y EL L at 2.8 carats per tonne S OWKN Diavik Diamond Mine IF E (31 December 2015) • Total rough diamond production – CAN ADA 97.5 million carats (2003-2015) 06 Bathurst Inlet Jericho Diamond Mine Tahera (closed) Northwest Territories Nunavut Contwoyto Lake Ekati Diamond Mine Dominion Diamond Corporation Gameti Wekweeti Lac de Gras Diavik Diamond Mine Rio Tinto/Dominion Diamond Corporation Mackay Lake Winter Road Wha Ti Snap Lake Diamond Mine De Beers (care and maintenance) Behchoko Gahcho Kue De Beers/Mountain Province Yellowknife N’dilo Dettah Lutsel K’e Fort Providence Great Slave Lake Hay River Fort Resolution In 2015, the first season of A21 rockfill dike construction, work was completed on schedule and on budget. One of the biggest construction aspects of the US $350 million project is crushing rock. The A21 dike will require three million tonnes of crushed rock and, at year-end, Diavik was ahead of plan. Most importantly, the work was completed safely. A big focus for the A21 team, and its contractors, is working on the water and vehicle interactions. Operations Development of the A21 ore body is a major investment in Diavik. Ore from A21, due in late 2018, will ensure consistent production levels over the final several years of Diavik’s mine life. Proud of our legacy to the North A21 on schedule and on budget A21 is being constructed with an integrated project team; one which has the A21 team working with many other Diavik departments, including fixed plant and health, safety, and environment. In 2016, rock crushing, dredging, and dike construction will continue. Dike enclosure will be the big milestone in 2016, a year which will also include the start of construction of the central cutoff wall. Other work done last year included building roads and laydown areas, dewatering/dredging pipeline construction, dredging, and north and south embankment construction. 07 Operations Proud of our legacy to the North 08 Operations Proud of our legacy to the North Mining and production For the year, Diavik produced 6.4 million carats of worldclass rough diamonds. The total was about 10 per cent below the previous year’s production. The decline was primarily due to lower mining rates in A154 North pipe and lower grade in A418 pipe. It was also due to the mine’s process plant shutdown for three weeks over the last few months of the year. Total ore mined, 2.1 million tonnes, was as planned. At year-end, ore stockpiles were estimated to contain about 250,000 carats. Diavik produces one of Canada’s largest diamonds Weighing 187.7 carats, it is Diavik’s largest gem-quality rough diamond and one of the largest ever discovered in Canada. Known as the Diavik Foxfire, it was showcased during an exclusive preview at Kensington Palace in London in December. The Diavik Foxfire also has an indigenous name: Noi eh Kwe (caribou crossing stone), which references the strong ties to the land and its legacy. It is likely that the 187.7 carat rough diamond will yield at least one very large polished diamond destined for an exclusive heirloom piece of jewellery. 09 Operations Proud of our legacy to the North Proven and probable reserves 31 December 2015 Pipe Tonnes (millions) Carats/ tonne Carats (millions) A21 3.7 2.7 10.0 A154S 1.5 3.3 5.1 A154N 8.8 2.4 20.8 A418 4.6 3.6 16.7 Stockpile 0.1 3.5 0.3 18.7 2.8 52.8 Total Some numbers may not add due to rounding. These reserves reflect the available technical information and are current at the time of publication of this report. The information that relates to ore reserves is based on information compiled by Calvin Yip, a Competent Person who is a Fellow of the Australasian Institute of Mining and Metallurgy and a full-time employee of Diavik. Calvin Yip is a Qualified Person within the meaning of NI 43-101. 10 The additional reserves include two million tonnes promoted from previously identified resource to reserve and several hundred thousand tonnes of new ore identified. As Diavik’s underground mine goes deeper, geologists are able to complete even deeper delineation drilling. The 2.8 million tonnes has implications for future years’ mine planning. Currently, Diavik mines about two million tonnes of ore annually. Eighty-five per cent of the road is constructed over frozen lakes connected by 65 land portages. Open for approximately eight weeks each winter, the ice road is a joint venture managed by Diavik Diamond Mines (2012) Inc., Dominion Diamond Ekati Corporation, and De Beers Canada Inc. The road opens to light loads and full weight capacity when ice thickness reaches 0.71 metres and 1.04 metres respectively. In 2015, Diavik trucked 2,795 loads (106,031 tonnes) of fuel, cement, explosives, equipment, and other materials over the winter road. Total northbound loads and tonnes for 2015 were 8,915 and 305,215. Total backhaul, all users, was 283 loads. The road opened February 1 and closed March 31. Operations Some 2.8 million tonnes, identified through ongoing drilling and evaluation by the mine’s geology team, have been added to reserves, more than offsetting the 2.1 million tonnes mined in 2015. Winter ice road Constructed annually for mine resupply, the Tibbitt to Contwoyto Winter Road is the world’s longest heavy haul ice road, extending 600 kilometres when built into Nunavut. Proud of our legacy to the North Reserves added In 2015, Diavik identified new reserves from within its A154 North ore body. At 2015 year end, Diavik ore reserves are 18.7 million tonnes, up nearly 600,000 tonnes year over year. Total carats are 52.8 million, down about 500,000 carats. Prior to commercial production, which began in 2003, Diavik projected a 16 to 22 year mine life. Diavik’s life of mine plan is to have consistent production past 2023. Doing so would result in Diavik successfully achieving, and potentially exceeding, the high end of its projected mine life. 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 Mine life A154 open-pit A418 open-pit A154/A418 underground A21 open-pit Mine schedule subject to market conditions, further resource evaluation, continued mine planning, etc. 11 Economic prosperity Proud of our legacy to the North Employment Diavik provides significant employment opportunities to the Northwest Territories and the West Kitikmeot region of Nunavut. These opportunities include full-time operational employment as well as seasonal term employment across various projects, including the A21 dike construction, the processed kimberlite containment dam raise, and the winter road. 2015 Operations Employment (DDMI and Contractors)* Total 1,134 (31 December 2015) 19% northern Aboriginal (213) 29% northern non-Aboriginal (333) 6% southern Aboriginal (67) 46% southern non-Aboriginal (521) *DDMI employed 722 direct employees in 2015, of which 54% were northern and 32% were Aboriginal. Employment by gender Male 989 (87%) Female 145 (13%) Total (31 December 2015) 12 1,134 Located in a valley created by glaciation, it initially included two dams, which have ultimately been connected to form a structure with a circumference of 5.6 kilometres. In November 2015, the PKC construction team completed a multi-year, five metre dam raise. Known as phase 6, this included rock placement, embankment sloping, heat-welded liner installation, and bedding material placement. The PKC dam varies between 18 and 48 metres in height. It holds 25.7 million tonnes of processed kimberlite and will be modified to store a total of 45.2 million tonnes. For the construction work, Diavik focused on hiring northern workers. Overall, 84 northerners gained seasonal employment. Over the past three years, total hiring was 63 per cent northern, of which 43 per cent was northern Aboriginal. Economic prosperity Proud of our legacy to the North Processed kimberlite containment construction completed Among Diavik’s key civil structures is its processed kimberlite containment facility, or PKC. A lined, engineered structure, and one which is encircled by a rockfill dam, it is the mine’s permanent safe storage area for waste rock generated by processing kimberlite. As the mine continues to process ore from the A154 and A418 ore bodies, and with A21 ore due in 2018, there is one more raise planned for the PKC. Throughout operations, geotechnical monitoring includes collecting data on water levels, seepage, and quality. PKC fact file • Thermistors at 45 locations to monitor ground temperature (design includes frozen foundation). • Slope inclinometers at four locations to monitor lateral deformation in the dam embankments. • Piezometers at 25 locations to monitor upstream and embankment pressure.

Several hundred people, working for Diavik and its contractors, will be required to construct the A21 dike. Once A21 construction is complete, Diavik will require about 80 people to open-pit mine the A21 ore body. These would be new full-time roles. Overall total 30 97 Throughout 2016, Diavik staff will continue to focus on hiring northern by providing local communities with information about employment opportunities. 14 A21 construction employment Underground mine production team Northern Aboriginal 49 (26%) Other northern 52 (27%) Total northern 101 (53%) Southern Total (31 December 2015) 89 (47%) 190 Economic prosperity Proud of our legacy to the North Employment history (individuals) 2012 2013 2014 2015 Northern Aboriginal 206 (19%) 202 (20%) 194 (20%) 213 (19%) Other northern 302 (28%) 283 (28%) 254 (27%) 333 (29%) Total northern 508 (47%) 485 (49%) 448 (47%) 546 (48%) Southern 563 (53%) 512 (51%) 500 (53%) 588 (52%) 1,071 997 948 1,134 Total 15 Economic prosperity Proud of our legacy to the North Spending In 2015, Diavik continued to focus on northern businesses and, in so doing, ensured major benefits flowed to local firms, many of which are Aboriginal. Two-thirds of spending, $259.2 million, was with local businesses, an increase over the $250.9 million spent with northern companies in 2014. Of the 2015 northern spend, $109.8 million was with Aboriginal businesses. Since 2000, Diavik has spent $4.9 billion with local businesses, or 71 per cent of the total business spend of $6.8 billion. Of the $4.9 billion in northern spend, $2.5 billion has been spent with northern Aboriginal businesses and their joint ventures. 2015 Operations Spending $149.4 million 39% other northern $126.9 million 33% southern 16 $109.8 million 28% northern Aboriginal $7,000 $2,526 $6,500 $6,000 $5,500 MILLIONS OF DOLLARS $5,000 $4,500 $4,000 Total northern spend $4,852 $2,326 $3,500 $3,000 $2,500 $2,000 $1,910 Economic prosperity Proud of our legacy to the North Total Cumulative Spending $1,500 $1,000 $500 0 2000-2015 Northern Aboriginal Other Northern Other Canadian Annual Spending $1,200 $604 $1,100 $1,000 MILLIONS OF DOLLARS $900 $800 $700 $276 $254 $600 $270 $500 $224 $245 $400 $300 $200 $145 $125 $115 $178 $180 $113 $310 $66 $120 $100 0 $256 $197 $58 2000-2002 2003 (Capital) $71 $143 $155 $112 $147 $206 2004 $144 $101 $108 2005 2006 $146 $215 $84 $76 $116 $135 2008 2009 2010 $101 2011 $149 $141 $143 $105 2007 $110 $110 2012 2013 $127 $81 2014 2015 (Operations) Northern Aboriginal Other Northern Other Canadian 17 Economic prosperity Proud of our legacy to the North Spending by category and priority group* Category Other northern Total northern Southern Total Freight, cargo, transport $14.8 $28.0 $42.7 $1.2 $43.9 Outsourced labour $61.1 $5.5 $66.6 $30.3 $96.9 Human resources $0.1 $1.6 $1.7 $2.2 $3.8 Passenger transport $7.6 $0.3 $7.9 $0.0 $7.9 Fuel, lubricants $0.0 $0.0 $0.0 $0.0 $0.0 Community relations $0.2 $0.3 $0.5 $0.1 $0.6 Consumables $14.0 $91.9 $42.1 $59.7 $164.8 Construction $0.9 $7.4 $8.3 $4.0 $12.3 Professional services $5.6 $2.8 $8.4 $7.9 $16.3 Telecommunications $0.0 $1.0 $1.0 $5.2 $6.3 Financial $4.9 $11.2 $16.1 $15.6 $31.7 Other $0.6 $0.6 $1.2 $0.3 $1.5 $109.8 $149.4 $259.2 $126.9 $386.1 Total spend * $ millions Some totals may not add due to rounding. 18 Northern Aboriginal Diavik is a strong supporter of the traineeships for graduates of the underground miner program and mineral process operator technician. Since 2014, Diavik provided traineeships for eight underground candidates (all northern Aboriginal), who were offered six-month training positions. Of these eight, four were offered and will transition to full-time positions, and the other four will complete their practicums in 2015. In addition, three candidates were offered traineeships in mineral processing and are expected to complete them by March 2016. As a sponsor of the NWT Mining Leadership Award, Diavik was extremely happy to support the award being granted to Shelby Nadli of Fort Providence, NT. Training Diavik has a long standing relationship with the NWT Mine Training Society. A founding member in 1998, Diavik has continued its support for this partnership-based not-forprofit organization. Proud of our legacy to the North NWT Mine Training Society Members of Diavik’s Health, Safety, and Environment team worked very closely with the Society to develop an industrial safety training boot camp, which is now recognized by all three diamond mines, as well as advanced mineral exploration projects in the Northwest Territories. It is also recognized by the Workers’ Safety and Compensation Commission. To date, 109 candidates have been certified for safety leadership and have obtained their tickets in lock out/tag out procedures, working at heights, confined space, standard first aid, CPR and AED, WHMIS, and radio operators certificate (aeronautical). The society has been working with employers, like Diavik, to place over 1,100 people in long-term employment. This represents five per cent of the entire labour force in the NWT. 19 Training Proud of our legacy to the North In the spring of 2015, Diavik donated an MHT436 haul truck to the society to assist with the delivery of the underground miner program. This donation results in $300,000 in annual savings for the society, as it no longer rents the equipment. Skilled trades Diavik has committed to train between eight and 18 apprentices annually. Diavik’s apprenticeship program increases skills and provides opportunities for employees. The society has received an extension of its funding to 30 September 2016 and looks forward to working with its partners on submitting a long-term training plan, which will include surface mining, underground mining, mineral processing, safety training, and diamond drilling. At year end, Diavik supported 29 apprentices, with 21 being northerners; of the 21 northerners, eight are northern Aboriginal. The socio-economic monitoring agreement apprenticeship commitment is eight to 18. Mining Industry Human Resources Council Certification In 2015, Diavik continued its participation in the Mining Industry Human Resources Council’s (MiHR) national certification programs for underground miners and mineral processors. Through these programs, individuals who achieve certifications demonstrate they have the skills that meet national standards, which have been developed by MiHR and the mining industry. Diavik has supported the MiHR certification, a national standardized certification program, since inception in 2011.

The renewal comes after the Wek’eezhii Land and Water Board recommended the renewal approval to the Government of the Northwest Territories. The licence reconfirmed existing environmental limits and adds engineering conditions, new to the NWT. Overall, the licence sets out the conditions and requirements for Diavik to continue to successfully protect the environment in which it operates and ensures it meets the highest standards. Diavik’s commitment to a safe and successful closure started before construction of the mine and it has been undertaking closure planning, consultation, research, and progressive closure activities throughout operations. In 2023, Diavik will require a renewed water licence, which will include the closure and post-closure phases. 26 2014 2015 Fresh water used Fresh water for plant 400,961 428,018 404,206 Potable water 67,774 72,175 73,988 Dust management 39,365 50,494 47,512 Fresh water, other 0 0 50,826** 508,100 550,687 576,532 11,838,632 11,737,313 11,617,635 0 0 0 North Inlet to Lac de Gras (water treated through north inlet water treatment plant) 12,616,049 11,438,537 11,903,811 Total 12,616,049 11,438,537 11,903,811 1,806,263 1,259,135 1,118,940 275,730 1,190,855 1,124,851 66,064 70,945 71,261 Total Underground dewatering Effluent discharged to Lac de Gras Collection ponds to Lac de Gras (clean water) Recycled/reused water within plant Recycled processed kimberlite containment water Recycled north inlet water** Treated sewage effluent Collection ponds to processed kimberlite containment (silty water) Total * 1 m3 = 1,000 litres **drills 894,330 201,558 288,817 3,042,387 2,722,493 2,603,869 Health, safety, and environment 2013 Proud of our legacy to the North Water usage (m3)* 27 Health, safety, and environment Proud of our legacy to the North Mines complete North’s largest grizzly bear DNA study With its remote location in the tundra of Canada’s subarctic, Diavik Diamond Mine operates in one of the most challenging environments in the world – an environment it shares with grizzly bears. During the summer months, grizzly bears are often seen in the mine area. Diavik monitors their location with the intent to protect them and staff. While up to 20,000 grizzly bears remain in Canada, the country’s Committee on the Status of Endangered Wildlife lists the animal as a species of special concern because of its sensitivity to human activities and natural events. The Canadian Barren Lands, named for the region’s lack of trees, are the most northern and eastern limits of the continental grizzly bear range. The research project, conducted in partnership with neighbouring Ekati Diamond Mine, aimed to determine 28 whether mining-related activity has influenced the number and distribution of grizzly bears over time. This was the largest grizzly bear study ever completed in Canada’s Northwest Territories. Following a successful pilot, environmental teams from Diavik and Ekati began a two-year study, in 2012, to collect baseline data about bear populations. Using traditional knowledge from community elders, the teams designed and placed 112 bear posts across 16,000 square kilometres of tundra, collecting 4,709 grizzly bear hair samples for DNA analysis. Results show the local bear population is stable or even increasing. In 2013, the study detected approximately ten grizzlies in a 1,000 km2 area, three times the number detected in the 1990s. In May, the two mines were presented with the 2015 Mining Association of Canada’s Towards Sustainable Mining Environmental Excellence Award for the grizzly bear research. Health, safety, and environment Proud of our legacy to the North Emergency response team The Diavik Diamond Mine emergency response team includes over 60 volunteers from across all site departments. The team trains year-round and competes locally, regionally, and internationally to maintain its skills. Diavik’s mine rescue team has won three western regional mine rescue competitions (North America’s largest) and, in 2012, placed third at the 8th Annual International Mine Rescue Competition held in Donetsk, Ukraine. 29 Health, safety, and environment Proud of our legacy to the North Key performance indicator Lost time injuries Lost time injury frequency rate* Medical treatments 2014 2015 3 3 4 0.24 0.28 0.32 7 3 5 0.81 0.55 0.73 Significant potential incidents 7 3 4 Health and safety regulatory non-compliances 0 0 0 Environmental regulatory non-compliances 1 1*** 1**** Significant environmental incidents 0 0 0 Environmental management system Maintained ISO 14001 Maintained ISO 14001 Maintained ISO 14001 192,544 182,427 192,843 $159.0 million $150.7 million $150.4 million All incident frequency rate** Greenhouse gas emissions (+CO2 equivalent) Closure security***** * Lost time injury frequency rate (injuries x 200,000 hours ÷ total hours worked). ** All incident frequency rate (lost time injuries + medical treatments x 200,000 hours ÷ by hours worked). *** A single sample from the north inlet water treatment plant exceeded grease/oil limits; investigation was unable to determine the cause. **** During A21 dike construction, total suspended solids one-time event limit of 25 milligrams per litre exceeded; see turbidity barrier and regulatory exceedance text on page 35 for more detail. *****Under the Diavik environmental agreement, a security deposit for the performance of the joint venture’s reclamation obligations is required. 2015 changes included $1.5 million added under department of fisheries authorization for the A21 dike and $1.8 million was deducted under the water licence due to updated closure plans. Diavik practices progressive reclamation, which results in the lowering of the amount. Wind farm reducing reliance on diesel With its award-winning wind farm, the Diavik Diamond Mine is the global leader in delivering cold climate renewable energy. In 2015, the mine’s four turbine, 9.2 megawatt wind farm diesel fuel offset was 5.2 million litres, reducing its CO2e by 14,404 tonnes (6.5 per cent offset).

The eighth session brought together elders and youth, selected by their community organizations, to focus on Diavik’s closure plans in relation to water monitoring and the dike, which included reef construction and shoreline design options. The panel applied their knowledge of fish and water, as well as observations made during previous site visits and the 2015 aquatic effects camp, to identify concepts, values, understandings, and complexities to be considered for these areas during the closure planning process. The panel noted 33 specific recommendations relating to reefs and water monitoring at closure, and identified the following themes: • It is important to continually monitor water quality and quantity after closure, using both traditional knowledge and western science. 32 • With slight modifications, the current aquatic effects monitoring program traditional knowledge study is strongly supported and should continue (and be held at the same location until at least 2018). • Fish need to be respected and have different habitat considerations for different life stages. • Youth need to be involved, both now and in the future. • Diavik and the panel is a model for collaboration between western science and traditional knowledge. • The future is uncertain and efforts to increase energy efficiency and monitor for climate change are important. This session’s report, titled Focus on Reefs and Monitoring Water, summarizes the discussion held and considerations identified by panel members for each theme. To date, the panel has provided a total of 130 detailed recommendations for consideration by Diavik and other parties. Each panel report and a tracking table that captures all recommendations, as well as Diavik’s response to each, are submitted to the Wek’eezhii Land and Water Board as part of Diavik’s annual closure and reclamation plan updates. Diavik site services and mine operations teams assisted in constructing the large-scale test pile, while the environmental team provided monitoring. More than 100 people were involved in the study, including seven principal investigators, three Diavik staff, 18 research technicians, six doctoral fellows, more than 60 students, and a research council program officer. The ten-year, active, on-site research project was completed without a single safety incident. Diavik collaborated with researchers and scientists from Waterloo, Alberta, British Columbia, and Carleton universities, and the study resulted in a better understanding of acid rock drainage, with improved methods developed to predict its chemistry and manage its environmental effects. It will also help other mining companies worldwide to better understand waste rock behaviour and develop mitigation strategies to better protect the environment. The research employed synchrotron X-ray spectroscopy and advanced numerical models to study both biological and geochemical processes. Waste rock contains sulphide minerals that, when exposed to air and water, can result in poor quality drainage. If not managed properly, this can harm fish and aquatic life long after the mine has closed. Health, safety, and environment Proud of our legacy to the North Award for innovative waste rock research In February, Diavik’s waste rock research project, designed to protect fragile northern environments, received a Synergy Award for Innovation from the Natural Sciences and Engineering Research Council of Canada. At Diavik, waste rock is tested for sulphur, with higher sulphur rock segregated and placed strategically within the mine’s waste rock pile. A cover system for this rock has been developed that takes advantage of the permafrost environment to limit low-quality drainage. David Johnston, Governor General of Canada, presented the award at Rideau Hall in Ottawa to the project team which included Diavik’s Principal Adviser, Sustainable Development, Gord Macdonald. The research has been critical to verifying Diavik’s long-term closure plan and in reducing its closure liability bond by about C $40 million. The research benefits Diavik’s closure planning and the knowledge gained is applicable to all mine sites, particularly mines in northern environments. 33 Health, safety, and environment Proud of our legacy to the North 34 Traditional knowledge study focuses on fish, water quality As part of the Aquatic Effects Monitoring Program, a traditional knowledge study was conducted in August 2015. The study was conducted at a camp on the south shore of Lac de Gras and included elder and youth participants from the Kitikmeot Inuit Association, the Lutselk’e Dene First Nation, the North Slave Metis Alliance, the Tlicho Government, and the Yellowknives Dene First Nation. or submerged vegetation and animals, presence/absence of surface foam and/or vegetation, clarity, movement, temperature, and taste. Water samples taken from Lac de Gras were boiled into tea to evaluate for taste. Results from scientific analysis of fish health and water quality support observations made by traditional knowledge holders that the present status of the fish and water in Lac de Gras is good. The primary objective was to exchange information, resources, and knowledge between traditional knowledge holders and scientists. The focus was Lac de Gras fish and water health. Another objective was to meet the regulatory requirements for monitoring aquatic health. Participants acknowledged that Diavik is working hard to keep the fish and water healthy, and indicated the study embodies a new relationship model for industry and communities. Elders, youth, and scientists collaborated to set nets, inspect overall fish health, capture scientific data, and collected traditional knowledge observations for each fish. Elders then tasted a total of four fish that they baked, boiled, fried, and grilled. To document the program, a report entitled Feeling the Spirit Together: Monitoring our Land, Water, Fish and Air will be posted on the Wek’eezhii Land and Water Board web site in 2016 and a video documentary, We Fish Today, for Fish Tomorrow, will be posted on the diavik.ca web site. Similarly, camp participants used indicators grounded in traditional knowledge to evaluate water quality. From this perspective, camp participants deduced that water quality is good by virtue of observing the health of surrounding The silt curtain, which surrounds the work area, extends from the lake surface to just above the lakebed. It redirects silty water generated during dike construction to the lakebed. Silty water can be generated during dredging of the dike footprint and lakebed, placement of crushed rock for the dike, and from placement of the filter blanket (the lakebed layer of rock at the base of the dike). As part of its regulatory requirements, Diavik’s environment team conducts water quality monitoring. This includes daily sampling to measure total suspended solids. Samples are collected at a background location on the lake and at three stations outside the turbidity barrier. These samples are taken throughout the water column and are studied daily in Diavik’s on-site water quality lab. The total suspended solid level is a measure of how much silt is in the water. Diavik has one regulatory limit for total suspended solids, which is a one-time level of 25 milligrams per litre over background level of two milligrams per litre. In addition to sampling for total suspended solids, Diavik has two turbidity buoys located outside the silt curtain. Turbidity is a measure of the amount of light which passes through water. The buoys collect data and if turbidity increases, the buoys send data to Diavik’s security department which notifies the environment department. The data is monitored and analyzed and if needed, the mine’s trigger action response plan is activated to lower turbidity. Regulatory exceedance – silty water On 8 August 2015, silt levels exceeded the one-time event of 25 milligrams per litre above background levels. Weather conditions at that time included sustained high winds. The resulting wave action caused air to accumulate under the curtain which ultimately raised the bottom of the curtain off the lakebed. The exceedance was identified and corrective action was taken; specifically, extra anchor weights were attached to the curtain to return it to vertical positioning. In a matter of hours, silt levels returned to below the regulatory limit. As of 2015, this was the only exceedance (includes A154 and A418 dike construction). Health, safety, and environment Proud of our legacy to the North Turbidity barrier deployed for A21 dike construction During construction of the A21 dike, Diavik deploys a turbidity barrier, or silt curtain, into the waters of Lac de Gras. This is the same technology that was used during construction of the A154 and A418 dikes. Water monitoring Diavik’s water quality monitoring system includes a surveillance network program for monitoring water in and around the mine site, and an aquatic effects monitoring program which measures changes in the Lac de Gras aquatic environment. Results from water quality monitoring programs are collated and reviewed to identify the need for any follow-up action. Wildlife monitoring Diavik monitors the potential effects of the mine on wildlife and wildlife habitat. Monitoring is done to help Diavik determine if the predictions made in its environmental assessment are accurate and to help assess the effectiveness of mitigation strategies. Currently, Diavik conducts caribou, raptor, wolverine, grizzly bear, and other wildlife monitoring programs. 35 Health, safety, and environment Proud of our legacy to the North Caribou monitoring Caribou are a key indicator species because of their cultural and economic value to northern residents as well as being of ecological importance. Diavik conducts low impact behavioural surveys of caribou at varying distances from the mine. Regulatory requirements are governed by a variety of environmental acts and regulations that set specific conditions through various permits, licences, and authorizations as well as the environmental agreement. For example, the water licence establishes effluent criteria for waste water discharge to protect the water. Closure planning As a requirement of Diavik’s Type A water licence, environmental agreement, and land leases, a report is prepared annually to report on progress, research results, and ongoing alterations or changes to the interim closure and reclamation plan. The progress report is externally reviewed and approved. Fish and fish habitat are protected, monitored, and managed in accordance with the requirements of fisheries authorizations. Environmental compliance As part of its commitment to the environment, Diavik is a signatory to an environmental agreement with local Aboriginal groups, and the federal and territorial governments. Finalized in March 2000, the agreement formalizes Diavik’s environmental protection commitments, establishes reclamation security requirements, and provides transparency and oversight to local communities. 36 Land leases outline the requirements for responsible land management practices, including provisions for infrastructure, and waste and hazardous materials management. The public can view these various documents at a public library in the Environmental Monitoring Advisory Board’s office in Yellowknife and/or through the Wek’eezhii Land and Water Board public registry (online and library). Health, safety, and environment Proud of our legacy to the North Inspection and enforcement Government inspections provide assurances that Diavik remains in environmental compliance. In 2015, regular inspections were conducted by the territorial Department of Lands, which holds primary responsibility for enforcement and inspection of the legal provisions of permits and licences related to land and water use and waste management. Fourteen inspections were conducted by the Aboriginal Affairs and Northern Development Canada/Government of the Northwest Territories inspector in 2015. Inspection reports are included in the Wek’eezhii Land and Water Board online registry, which can be sourced from its web site (wlwb.ca). Environmental management system To manage its environmental protection commitments, Diavik has implemented an internationally certified Environmental Management System (EMS) that: • Identifies and priorities environmental risks; • Identifies activities to protect the environment; • Ensures employees are properly trained; • Anticipates and avoids environmental problems; • Ensures regulatory compliance and due diligence; and • Ensures consistency with corporate environmental policy. Certified under the internationally acknowledged ISO14001 standard, Diavik’s EMS is designed to be simple, understandable, easy to implement, and adaptable. Diavik’s EMS includes protection for wildlife, water, and fish habitat – issues of particular concern raised by local communities. 37 Health, safety, and environment Proud of our legacy to the North Environmental Monitoring Advisory Board In March 2000, the environmental agreement was signed by Diavik, the Tlicho Government, the Yellowknives Dene First Nation, the Lutsel K’e Dene First Nation, the Kitikmeot Inuit Association, the North Slave Metis Alliance, the Government of the Northwest Territories, and the Department of Indian Affairs and Northern Development. Through the agreement, the Environmental Monitoring Advisory Board was established as a not-for-profit organization that works independently and at arm’s length from Diavik and the other parties to the agreement. The Board’s mandate is to assist with the implementation of the environmental agreement. It also serves as an external reviewer of Diavik’s environmental performance.
