DMC QUICK FACTS Over its 36-year history, DMC Mining Services has consistently proven itself as an innovator in its field.

• The company started as Dynatec Mining Limited and was founded in 1980 by Dr. Robert (Bob) Dengler and W.M. (Bill) Shaver.

• In its second year in business, it started building the Macassa Mine shaft, for which, it still holds the record for the deepest single-lift timbered shaft in the world at 7,225 ft (2,202 metres).

• In 1992, it developed the Long Round Concept for shaft sinking, an innovation that improved productivity by 20%.

• The company used Rail-Veyor haulage technology for the first time in North America at Vale’s 114 orebody in Sudbury to drive twin drifts at over 400 ft (121 metres) per week.

• In 2013, DMC’s president and CEO, Bill Shaver, won the EY Entrepreneur of the Year Award for Ontario in the category of business services.

• The company initiated and developed leading edge, shaft sinking technology using Shaft Boring Roadheaders (SBRs) designed and built in Germany for a twin shaft project in Canada.

• In 2015, DMC’s Jansen team performed the first ever installation of shaft tubbing using a robotic arm called the Blairmore Ring Erector (BRE).

LONGEVITY THROUGH EVOLUTION Journey from Dynatec to DMC Mining Services Since its founding in 1980 as Dynatec Mining Limited, DMC Mining Services has been through a number of acquisitions, takeovers and mergers, underscoring the company’s ability to create value.

• In 1988, Dynatec became Dynatec International after making its first major acquisition. It bought Vancouver-based Tonto Mining and Tonto Drilling Services, which gave the company a base in Western Canada, South America and the Western United States. With the merger, the company reorganized into Dynatec International, a parent company with nine subsidiaries, drilling and mining equipment valued at over $50 million and staff of 800 people.

• In 1997, the company merged with Sherritt International’s hydrometallurgical technologies business and was publicly listed as Dynatec Corporation on the Toronto Stock Exchange.

• In 2007, Sherritt International acquired Dyantec for $1.6 billion. This included its stake in the Ambatovy nickel project in Madagascar and the major shareholder position of FNX Mining. As part of the deal, Sherritt dividended the ownership of FNX to their shareholders and sold Dynatec’s mining services division to its old partner, FNX Mining. The Mining Services Division changed its name to DMC Mining Services in 2008.

• FNX Mining merged with Quadra Mining in a $3 billion, merger of equals in March 2010. • In March 2012, Polish copper miner KGHM Polska Miedź bought Quadra FNX Mining for $2.9 billion in cash. DMC Mining Services is a division of KGHM.

SERVICES OFFERED Contract Mining DMC has a long history as a safe and efficient contract miner, including operation of the 2,500 ton per day Inco Shebandowan Mine in the 1990s, and the 500,000 ounce per year Goldcorp Red Lake Mine in the early 2000s. Today, the company continues to provide comprehensive services ranging from mine feasibility and underground mine design, including mine shafts, ore and waste handling systems, mine dewatering systems, backfill systems and ventilation systems. It also advises on equipment selection and procurement. Once the feasibility and design of an underground mine has been established, DMC is able to develop and operate the mine with its equipment, trained personnel and management systems. Where it assumes responsibility for mine operation, DMC hires staff, develops production budgets and schedules, produces reports, maintains regulatory permits and filings, manages operating staff and assumes overall responsibility for safety and loss control. Mine Shaft Sinking Mine shaft sinking is one of the most critical and technically difficult aspects of underground mine development and construction. A mine shaft must be completed and commissioned for an orebody before any other underground mine development can begin. Accordingly, mine owners place a premium on rapid sinking schedules. DMC has the experience, skilled workers and the specialized techniques and equipment necessary to complete technically 5

challenging projects - such as those involving poor ground conditions or extreme depth - on time and on budget. The company has a history of innovation and continuous technical improvements, such as its patented Long Round technology, which has increased the speed at which shafts can be completed. It was also chosen as the contractor to sink two 3,280 ft (1,000 metre) shafts at BHP Billiton’s Jansen Potash Project, using innovative Shaft Boring Roadheader technology that it initiated and developed from concept to shaft sinking. Conventional Mine Development DMC is able to offer a bundle of related services, including lateral development work consisting of access ramps, declines, drifting and cross-cutting. Mine Construction Mine construction services are specialized activities related to both surface and underground mines. The company’s mine construction work has included: refuge stations, underground explosives magazines, underground shops, crushing and conveying systems, sumps and dams for mine dewatering systems, ground stabilization through the installation of rock bolts and the application of shotcrete, grout injection and backfill. Services also include vent doors and shotcrete walls, hoist and fan foundation installations as well as electrical and mechanical installations for hoisting, ventilation and dewatering systems. Civil Construction The company also provides services to customers in the civil underground construction industry. They

have

completed

underground

work

for

hydroelectric facilities (powerhouse and tailrace tunnel excavations, tunnel rehabilitation), ground stabilization and construction work for the Sudbury Neutrino Observatory and established a freshwater reservoir and collection system by installing a concrete bulkhead and piping system in an adjacent abandoned mine. DMC has also built a pedestrian walkway and utility tunnel under downtown Salt Lake City. Most recently, it has completed civil raise boring work in Atlanta, and is currently raise boring on a major sewer project in Indianapolis. 6

Raise Boring and Raise Excavation Raise boring is a continuous, mechanical method of excavating vertical or near-vertical holes between two levels of an underground mine. The holes can be used for ventilation, manways and ore and waste transportation. Raise boring is generally considered a safer, faster and more cost-effective way of excavating raises than more traditional drilling and blasting methods. Raise boring techniques are also used to excavate various raises and shafts for civil construction projects. In particular, raise boring leaves smooth walls, allowing for more efficient ventilation. Raise bored holes can also be used for hoisting or egress shafts. DMC has a fleet of nine raise boring machines, over 7,500 ft (2,000 metres) of drill pipe and 16 reamers with capabilities from 28 inches (71 centrimetres) to 20 ft (6 metres) in diameter. The smallest drills operate in only 12 ft (3.6 metres) of headroom. Alimak Raising is a drill and blast method that enables mining approaches that cannot be carried out using raise borers. It has the added advantage of in raise access for the installation of ground support and grouting of water inflows as the raise is excavated. Alimak Raising is a viable alternative for occasions where raise boring may not be viable due to access or power considerations. DMC owns and operates a fleet of mechanized raise climbers for these applications. Engineering Services DMC’s evaluation and design services include concept, prefeasibility and technical engineering. The company’s technical engineering capabilities cover all the major disciplines (mining, civil, electrical, structural and mechanical). DMC provides technical engineering services to assess and optimize mining projects. The group’s expertise includes: mine planning (conceptual/feasibility/detail); equipment evaluation and selection; mine and facility design; flow sheet layouts; material handling; ancillaries/utilities design; transportation system design; and cost estimating. The group also has considerable expertise in contiuous improvement as well as engineering by design. The group uses 3-D modelling, finite element analysis and computer simulation on all engineering solutions, and uses an engineering package schedule (PAS) as a tool to monitor and track design progress. Our engineering clients have included major mine leaders such as Barrick Gold, BHP Billiton, Vale, Glencore, Newmont Mining and KGHM International. 7

RECENT PROJECTS DMC has had the opportunity to work on challenging and innovative solutions for mining projects around the world. Here are just a few examples. Jansen Project, Saskatchewan

•

Contracted to develop and deploy Shaft Boring Roadheader (SBR) technology at BHP Billiton’s Jansen project, in Saskatchewan

•

SBR eliminates key safety risks associated with conventional shaft sinking excavation with removal of excavated material and rock support all occuring simultaneously

In December 2010, DMC won a contract to sink two 3,280 ft (1,000 metre) shafts — a Production Shaft and a Service Shaft — at BHP Billiton’s Jansen potash project in Saskatchewan. In a first for the mining industry, the 9-metre-diameter shafts are being sunk mechanically, using two SBRs — a marriage of tunnel-boring, high-speed vacuum and traditional shaft sinking technology. The operation of the SBR is fully automated and improves work safety by removing workers from the bottom of the shaft. The SBR allows workers to stand at different platforms or decks above the bottom of the shaft. Ground support is installed on one of the decks above simultaneously as the SBR excavates, and material is removed through an automated vacuum system that is controlled remotely with cameras. DMC helped design the SBR in concert with Herrenknecht, a large, tunnel-boring company based in Germany, and BHP Billiton for use at Jansen. The SBR is designed to deal with rock strengths ranging from 5 to 120 MPa, and the telescopic Roadheader sinks variable shaft diameters from 26 ft to 32 ft (8 to 10 metres). 8

Vale’s 114 Orebody, Ontario

•

Contracted to provide development and construction services for the first underground installation of Rail-Veyor haulage technology at Vale’s 114 Orebody

•

Elimination of the “big truck” model for underground mine development

In 2011, DMC won a contract to conduct 10,000 ft (3,050 metres) of development and mine 200,000 tons (2,500 tons per day) of ore using Rail-Veyor haulage technology. An innovative ore-handling system that combines rail and conveyor technology, the Rail-Veyor was used at Vale’s 114 orebody in Sudbury. Outside of a Vale test site in 2008, it was the first time the technology was used in North America. The aim of the project was to prove that Rail-Veyor technology can speed up trackless development. Part of the concept was to drive smaller headings, because as mine tunnels have gotten larger over the past 30 years, development has gotten slower. There are also more challenges with ground support and having to remove more muck at a higher rate. DMC’s objective with the Rail-Veyor project was to see if it could drive twin headings — two sideby-side tunnels — at 400 ft (121 metres) a week. It exceeded that with progress of up to 470 ft (143 metres) a week.

Turquoise Ridge Gold Mine, near Golconda, Nev.

• •

Owned by Barrick Gold and Newmont Mining Job consisted of underground development

The project covered five years of work from January 2009 to October 2013. DMC developed over 15,000 ft (4,500 metres) of a 15 ft x 16 ft (4.6 x 4.9 metre) drift. This project also included the excavation of an underground opening 60 ft (18 metres) tall by 30 ft (9 metres) wide by 160 ft (49 metres) long for the new North Zone Backfill and Shotcrete plant that was also designed by DMC. During this time, DMC crews were integrated into the daily, weekly and monthly plans for the Turquoise Ridge Mine site. Working with the owner, DMC achieved the desired goals for the site and advancement required for the future development of the North Zone area. Using its own equipment, DMC crews integrated successfully with the Barrick Team.
