A SOLID RECORD OF SAFETY BY DESIGN

Over its 37 years in business, DMC Mining Services has established a reputation for safety, thanks to the company’s top leadership and its on-site supervisors.

To reinforce this culture of safety, DMC has set up a safety and health management system that defines our fundamental approach to managing and controlling workplace hazards and risk. The management system defines accountability and facilitates management’s effort to assure our projects are set up for success through safety design.

Safety programs in place include First Aid and CPR training, supervisor development programs, job specific training and project and field level risk assessments. An E-learning program offers a DMC company orientation module, 32-hour MSHA training and an eight-hour MSHA refresher training for on-site and remote access.

DMC has been recognized many times for its health and safety efforts. We were the runner-up in the Ontario government’s Workplace Safety North (WSN) workplace safety excellence audit in 2013, and won awards for having the lowest total medical injury frequency performance in 2011, and for workplace self-assessment in 2011.

DMC encourages reporting and collects leading indicators such as near misses, workplace interactions, five point safety system quality and action plan close out. Having this information helps management to understand what needs to be improved so future incidents or events can be prevented, and drives continuous improvement to achieve Zero Harm.

The company has a philosophy at its core of Zero Harm, and is constantly looking to improve safety.

OUR SERVICES

Mine Shaft SinkingMine 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 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 foot (1,000 meter) shafts at BHP Billiton’s Jansen Potash Project, incorporating Rio Tinto Mine of the Future ™ technology that it developed with Herrenknecht AG in Germany.

Raise Boring and Raise ExcavationRaise 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.

7

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 feet (2,000 meters) of drill pipe and 16 reamers with capabilities from 28 inches (71 centimeters) to 20 feet (6 meters) in diameter. The smallest drills operate in only 12 feet (3.6 meters) 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.

Mine ConstructionMine 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.

Conventional Mine DevelopmentDMC is able to offer a bundle of related services, including lateral development work consisting of access ramps, declines, drifting and cross-cutting.

Civil ConstructionThe company also provides services to customers in the civil underground construction industry.

DMC has 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. DMC has completed civil raise boring work in Atlanta, and a major sewer project in Indianapolis.

Engineering ServicesDMC’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 continuous 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.

Contract Mining ServicesDMC has a long history as a safe and efficient contract miner, including operation of the Inco Shebandowan Mine, the Goldcorp Red Lake Mine and the Midas Joint Venture Mine.

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.

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 S.A. bought Quadra FNX Mining for $2.9 billion in cash. DMC Mining Services is a division of KGHM International, which is the successor of Quadra FNX Mining and operates today as the international arm of KGHM Polska Miedź S.A.
