COMPANY CHANGES

Navachab Gold Mine changed ownership on 1 July 2014 from AngloGold Ashanti Pty (Ltd) to QKR .

LEGAL COMPLIANCE

Navachab Gold Mine has a very comprehensive Environmental Management System which was implemented in accordance with the Initial Environmental Review Report done by Envirolink in April 1997. The review report as well as the complete Environmental Management System (EMS) was submitted to the Ministry of Environment and Tourism for approval (First page of Environmental Review Report Addendum A).

EIA for the Dense Media Separation (DMS) Plant was done by A Speiser Environmental Consultants CC in May 2009 (Addendum B) and first Environmental Clearance Certificate (ECC) was issued by Ministry of Environment & Tourism (MET) on 22 July 2011 (Addendum C).

The current ECC expires on 31 August 2019 (Addendum D) and this report accompanies the application for renewal.

ISO14001 CERTIFICATION

The EMS was first ISO14001 certified on 20 April 2007. Navachab Gold Mine has maintained its certification system since and the next certification date is 19 April 2019.

EMS OBJECTIVES & TARGETS

An Environmental Risk Assessment (ERA) was carried out as part of the initial EIA and Objectives and Targets are set annually. These Objectives and Targets are implemented and monitored by the EMS procedures set out in Section 6.

EMS PROCEDURES & MONITORING

The following EMS procedures are in place to guide and monitor the various environmental aspects, objectives and targets for the activities under ML 31 Accessory Works.

6.1 PR/ENV/064 – AIR & CLIMATE Dust monitoring is done continuously with fall out buckets. In addition, a PM10 monitor is used in situations where dust levels are exceedingly high.

6.2 PR/ENV/065 – SOIL, VEGETATION, LAND CAPABILITIES AND AESTHETICS Ongoing rehabilitation of WRD’s as they are handed over by Mining Department. No tree planting activities took place due to the continued drought conditions.

6.3 PR/ENV/066 – MINE EXTENSIONS & CHANGES

No extensions of the PCP are planned.

6.4 PR/ENV/067 – WATER SAMPLING

Groundwater monitoring is done on a monthly and quarterly basis according to the conditions in the Waste Water and Effluent Disposal Exemption Permit 604 (Addendum E).

6.5 PR/ENV/101 – WILDLIFE & RESERVE MANAGEMENT

Navachab Farm (outside of the active mining area) is maintained as a safe haven for game. Game animals can roam freely as there is no game fencing around the farm and no hunting is permitted.

6.6 PR/ENV/102 – MINE CLOSURE

Mine closure calculations are kept up to date with new developments and relevant closure costs.

6.7 PR/ENV/103 – WILDLIFE EMERGENCY PREPAREDNESS

This procedure mainly deals with wildlife emergencies including snared animals and animals infected with rabies that have to be put down.

6.8 PR/ENV/104 – BIODIVERSITY AND INVASIVE SPECIES

Biodiversity hotspots are identified and monitored and invasive species like Prosopis and Wonderboom are eradicated on ad hoc basis.

6.9 PR/ENV/201A – SALVAGE DISPOSAL

All waste material is placed in marked telecons and managed according to the Navachab Waste Management guidelines.

 Salvage items are taken to the salvage yard for storage and reuse. No salvageable items are landfilled. These include selling of: o Bulk steel, vehicle batteries, motors to scrap metal dealers o Tyres to scrap tyre dealers o Bulk plastic drilling bags to plastic recyclers o Small scrap items including redundant equipment and furniture, wooden crates / planks / pallets, empty drums, building materials, conveyor belting etc are sold on tender to employees and residents

6.10 PR/ENV/201B – WASTE DISPOSAL

 Hazardous Waste streams: o Medical waste taken to Walvis Bay Hazardous Waste site for incineration o Hydrocarbon solid waste removed ad hoc by WESCO and disposed at the Walvis Bay Municipal Waste site o Used Oil to WESCO and EXIGRADE o Cyanide Waste burnt in Cyanide burning area at the Ore Processing Plant under Ministry of Health and Social Services (MoHSS) Exemption Permit (Addendum F).  Non-hazardous Waste streams: o Remaining paper, plastic, boxes and food waste dumped and burnt at the landfill. Due to the baboon plaque on site all domestic waste items have to be burnt to prevent the baboons from strewing the waste all over site.

6.11 PR/ENV/301 – DUST SUPPRESSION Dust suppression is done with water bowsers on a fixed daily programme

6.12 PR/ENV/501 – CLEAN-UP OF HYDROCARBON SPILLAGES Any hydrocarbon spillages are cleaned up according to procedure and soils rehabilitated.

ENVIRONMENTAL INCIDENTS AND CORRECTIVE ACTIONS

Environmental incidents reported were mainly resulting from high dust levels due to the extremely dry conditions and hydrocarbon spills. Incidents are addressed immediately.

FUTURE ACTIVITES

All biodiversity exclusion zones and protected tree species will be indicated for avoidance in future mining plans. Monitoring and measurement of environmental parameters will continue as per EMS.
