Gahcho Kué Mine Draft Emergency Response Plan November 2013

Gahcho Kué Mine - i - November 2013 Emergency Response Plan Version 1 PLAIN LANGUAGE SUMMARY (De Beers) is planning to build the Gahcho Kué Diamond Mine (Mine) in the Northwest Territories (NWT) in addition to operating a winter access road to the mine site. The Emergency Response Plan (ERP) has been developed to describe the standards and specific procedures that will be followed by De Beers and its contractors in the unlikely event of an emergency related to the Mine. It follows De Beers guiding principles which include maintaining personnel safety while minimizing impacts to the environment, neighbouring communities, productivity, property and assets. During the construction phase of the Mine, this document will serve as operational guideline for the Engineering, Procurement, and Construction Management (EPCM) consultant and De Beers to ensure appropriate management oversight is implemented during an emergency. The ERP will be enacted when an incident (i.e., accident, fire, spill, personal injury etc.) occurs beyond the control of the personnel at the scene which includes the mine site, winter road and any other areas related to the Mine. Included in the ERP are the roles and responsibilities for De Beers and their contractors in addition to the responsible regulatory authorities for particular emergency situations. Specifically, the roles of the Project/ Mine Manager, Construction Manager, Site Safety Manager, Emergency Response Team Leader, Emergency Response Team, Medical Personnel, Site Environmental Superintendent, and Protective Services Manager are listed. Moreover, the ERP lists how each role is to interact for situations ranging from Minor Emergencies (Level 1) to a Crisis (Level 4). This includes a communication protocol, sounding alarms, assessment of the situation, response and debriefing. The ERP then details how and when outside agencies such as the Royal Canadian Mounted Police, Canadian Forces Search and Rescue, Air Ambulance, Fire Service, Aboriginal Affairs and Northern Development Canada, Environment Canada, Fisheries and Oceans Canada, Environment and Natural Resources Canada, The Workers Safety and Compensation Commission of the Northwest Territories, The Government of the Northwest Territories and Aboriginal Parties are to be contacted. Finally, the protocol for returning to work following an emergency is outlined.

Gahcho Kué Mine - 1 - November 2013 Emergency Response Plan Version 1 1 INTRODUCTION The Emergency Response Plan (ERP) has been developed to describe the standards and specific procedures that will be followed by (De Beers) and its contractors in the event of an emergency related to the Gahcho Kué Mine (Mine). During the construction phase of the Mine, this document will serve as operational guideline for the Engineering, Procurement, and Construction Management (EPCM) consultant and De Beers to ensure appropriate management oversight is implemented during an emergency. Emergency situations and corresponding procedures are defined including roles and responsibilities and communication with appropriate regulatory authorities. The document is also intended to serve as a training and reference guide for staff and contractors. Emergency Response Plans will be updated at various stages throughout the life of mine to reflect the operating conditions and ensure conformance with standards.

Gahcho Kué Mine - 2 - November 2013 Emergency Response Plan Version 1 2 PURPOSE This standard establishes specific procedures for the Mine that will be implemented in the event of an emergency and ensures that the EPCM consultant and De Beers will have proper management oversight during the emergency. An emergency response is a reflection of the way a corporation conducts its business. The EPCM consultant and De Beers are responsible corporations that conduct business to the highest of ethics and within the laws of Canada. The priorities include: personnel safety (workers and public); minimal impact on the environment; minimal impact on property and assets; neighbouring communities; maintain Mine schedule; minimal emergency response time; optimal response effectiveness; coordination with regulatory agencies and industry; minimal loss of productivity; and EPCM consultant s and the Owners Corporate Reputation. This document is also intended to be used as a training and reference guide for personnel in the performance of their duties during emergency situations. It is intended to ensure that a fast and organized response is carried out SAFELY, EFFICIENTLY AND EFFECTIVELY. These practices are not intended to be rigid. Deviations may be necessary, if the situation dictates, to allow flexibility to tailor the response for the emergency at hand. DO NOT UNDER REACT. The intent of EPCM and De Beers is for the response to be managed safely and competently within its resources and capability.

Gahcho Kué Mine - 3 - November 2013 Emergency Response Plan Version 1 3 SCOPE AND INTENT 3.1 SCOPE 3.2 INTENT This procedure applies to all Mine areas that may be involved in an emergency and is intended to ensure that the Mine is adequately prepared to respond to any emergency during the construction phase. It covers the following types of emergencies: incident resulting in fatality; incident resulting in injuries; fire and or explosion; weather/whiteouts; hazardous chemical/oil spill on water or land; rescue from height/depth or confined space; vehicle/equipment accident; bomb threat; terrorism/violence threat; building evacuation; winter road incident; and aircraft emergency. The ERP is enacted when an incident (i.e., accident, fire, spill, personal injury, etc.) occurs that is beyond the control of the personnel currently at the scene. Normal departmental procedures should be followed during any incident until it is determined that the situation is beyond the control of the personnel on the scene, or the normal departmental procedures have broken down or are unavailable. At this point the ERP should be invoked. The emergency response procedures and the personnel and department responsibilities presented here, apply to all types of emergency situations that may develop at the mine site, on the winter road, or any other areas related to the Mine.

Gahcho Kué Mine - 4 - November 2013 Emergency Response Plan Version 1 In the event of an emergency that requires communication with parties external to the Mine, the procedures in the Northwest Territories (NWT) Crisis Management Plan will be initiated. Figure 1 shows an overview of the Emergency Response Flow Process and communication protocol at the Mine. The function and responsibility of the various departments and individuals identified in Figure 1 are discussed in the following sections of the plan.

Gahcho Kué Mine - 15 - November 2013 Emergency Response Plan Version 1 8 PROCEDURES 8.1 REQUIREMENTS A system shall be in place to ensure that the Mine ERP is tested, documented, regularly updated and clearly communicated. The plan addresses: 8.2 USE OF THIS PLAN mine hazardous activities that could occur; response strategies for reacting to potential emergencies; details of responsibilities and authorities in regards to the various types of potential emergency situation; and medical assistance and follow-up plan. ERT s availability to respond and assist during emergencies, as required. Integrate the Mine ERP being with those of the communities and/or responsible authorities where there is an interface. Emergency simulations program to test the effectiveness of the ERP. Recommendations resulting from the emergency simulations program which should be documented and communicated to the appropriate level within the Mine team. This plan has been divided in two parts: The main body of the plan describes the procedures and protocols for emergency response within the Mine. The appendices provide checklists and procedures to be followed in the event of an emergency. These are presented in clear, concise language, and describe the responsibilities and actions that individuals should take during an emergency. 8.3 MINE EMERGENCY RESPONSE STRUCTURE The Mine shall maintain an emergency response organization as follows: Emergency Response Coordinator (ERC) Site /Construction Manager.

Gahcho Kué Mine - 16 - November 2013 Emergency Response Plan Version 1 Incident Commander Site Safety Manager or designate. Emergency Response Team ERT Volunteers from Contractors and Mine personnel will only undertake actions they are trained and competent to perform. The ERT shall assist any external emergency services upon arrival. 8.4 CLASSIFICATION OF EMERGENCIES The emergency response plan is based upon a four-tiered structure. Emergencies are identified and categorized into one of four levels, depending upon the nature and severity of the incident. Each level is managed by an escalating degree of management seniority and external assistance. The ERP provides the flexibility to tailor the size of the response to the specifics of the incident and allows for rapid adjustments as the incident evolves. The initial determination of the event classification, when notified, is made by local management with input from field personnel. However, the event could be subsequently reclassified upon further review. It is essential to define the level of response required as quickly as possible, in order to provide an appropriate response to the situation. A Mine incident is escalated to a Level 1 or Level 2 emergency by sounding an alarm or summoning the ERT to respond to an incident. Most incidents are not severe enough to warrant classification beyond a Level 1 or Level 2, and are handled by site emergency response and medical personnel. Escalation from Level 2 to a Level 3 or Level 4 is decided by the Emergency Response Coordinator in consultation with the Incident Commander in the Emergency Operations Centre (EOC). A Level 3 or Level 4 emergency is considered to be a Crisis and procedures and protocols are defined in a separate Crisis Management Plan. levels. Each emergency situation is different at its occurrence and will have the potential of developing into a more serious situation if not addressed immediately. Each situation can be classified, generally, as falling under any one of the below noted

Gahcho Kué Mine - 17 - November 2013 Emergency Response Plan Version 1 8.4.1 Minor Emergency Level 1 A Level 1 emergency is triggered when someone on site triggers an alarm or summons ERT or medical personnel to an incident scene. Local on-duty employees trained to respond to the particular type of emergency addresses the situation. Examples of minor emergencies are: small fire; minor oil spill easily contained; and minor vehicle accident with no injuries. Site ERT and Mine management are notified immediately. 8.4.2 Serious Emergency Level 2 A Level 2 emergency is one for which the potential human and environmental exposure goes from low to moderate, and can be corrected with on-site resources. A Level 2 response is managed by the Mine ERT who may also call on third party emergency services for assistance, should the incident warrant it. Examples of serious emergencies: moderate fire; serious vehicle accident resulting in injury; structural failure; weather emergency; moderate chemical spill contained with mitigations; and moderate plant and/or equipment damage. Site ERT and Mine management are notified immediately. 8.4.3 Crisis Level 3 A Crisis - Level 3 is one with regional implications, where potential human, environmental, or corporate exposure is significant. A Level 3 emergency requires the help of off-duty and/or off-site people, outside vendors, as well as

Gahcho Kué Mine - 18 - November 2013 Emergency Response Plan Version 1 local police, fire and/or emergency medical service crews. Media and/or other stakeholders are inquiring about the situation. Details of the incident or situation are known outside the corporate office or operation. When an emergency has been elevated to a Level 3 or Level 4, it becomes a Crisis and is to be managed by following the Crisis Management Plan. Examples of Level 3 situations: major equipment fire; structural failure; missing persons requiring Department of Defence search and rescue deployment; bomb threat/extortion; collision road accident with multiple casualties; and major environmental spill or release. The Emergency Response Coordinator (ERC) is responsible for coordinating logistical support to the impacted area. Logistical support includes: 8.4.4 Crisis Level 4 overall management of emergency and coordinating broader support; search and rescue services; liaison with government representatives; and liaison with contractors. In a Crisis Level 4, the situation is out of control and will impact an extended area and/or numerous people indefinitely. Normal business operations will be curtailed and employees diverted from routine duties until situation resolved. EPCM, Owner and third party resources would be deployed to respond to a Level 4 emergency. Regulated authorities may assume overall responsibility. Federal and territorial agencies may be called in to assist. Examples of Level 4 situations:

Gahcho Kué Mine - 19 - November 2013 Emergency Response Plan Version 1 major structural fire; missing persons requiring Department of Defence search and rescue deployment; death and/or multiple fatalities; missing or crashed aircraft; and major environmental spill or release. 8.5 EXTERNAL EMERGENCY SERVICES AND REGULATORY AGENCIES Regional emergency services (Royal Canadian Mounted Police [RCMP], Coast Guard, Environment Canada, Department of Defence, Transport Canada and other agencies) have legislative authority to control specific incidents and emergencies when called onto the Mine. In all circumstances, the Mine ERT will support the external emergency services. All external emergency services will be contacted by Mine personnel to review the scope of the Mine and communicate required services in case of incident. Mine contracted environmental service provider will work within the requirements established by the legislative authorities. To effectively work with governmental agencies, Project leadership personnel will ensure the following: Appropriate government agencies participate in the pre-planning measures for emergency response. All participants understand their respective roles and responsibilities and how to access additional available resources. All contracted emergency service providers are included in pre-planning and simulations. Everyone agrees to the use of common terminology and knows what it implies with respect to command and control of the emergency incident. Agencies are involved in simulations/drills. 8.5.1 Royal Canadian Mounted Police Provide law enforcement services including: maintaining law and order;

Gahcho Kué Mine - 20 - November 2013 Emergency Response Plan Version 1 protecting life and property; coordinating search and rescue; ensuring all victims are registered; assisting with community/public evacuation; providing security, traffic and crowd control, as required; acting on behalf of the Coroner, Coroners Act; and notifying next of kin of fatalities and/or serious injury. 8.5.2 Canadian Forces Search and Rescue The Air Force shares responsibility for search and rescue in Canada by drawing support from the Canadian Coast Guard and from a vast network of civil and government organizations, volunteers and other agencies. It begins with a distress call to one of the three Joint Rescue Coordination Centres (JRCCs) staffed by military and Coast Guard personnel or to one of the two Maritime Rescue Sub-Centres (MRSCs) staffed by Coast Guard personnel.

Gahcho Kué Mine - 21 - November 2013 Emergency Response Plan Version 1 Figure 2 Location of Joint Rescue Coordination Centres in Canada The JRCC/MRSC then verifies that the call is a genuine emergency. The next stage is swift and decisive, with the JRCC/MRSC tasking the appropriate resources (Resource locations as indicated on the following map). If it's a maritime emergency, the Canadian Coast Guard and its Auxiliary volunteers are mobilized. If it's an aeronautical emergency, the Air Force is called into action, as can the many volunteers of the Civil Air Search and Rescue Association (CASARA), station located in Yellowknife, NWT. Within minutes of an alarm being sounded, the crews are briefed, search areas assigned and the search and rescue teams are dispatched to the scene to find, administer medical attention, and rescue the victims. 8.5.3 Ambulance Service / Air Transport Service Provide care services including:
