5. Environmental Management: Groundwater Quality

6. Environmental Management: Groundwater Quality
A groundwater monitoring programme was established with the aim to asses impacts and/or any potential contaminants on groundwater quality.
The programme follows the prescribed plan set by Jones and Wagner (November 2012) that formed part of the Tschudi Project EIA.

7. Environmental Management: Potable & Effluent Water Quality
POTABLE WATER MONITORING PROGRAMME
To ensure that water used for drinking purposes on the mine is potable and good for human consumption.
EFFLUENT MONITORING PROGRAMME
Monitor effluent quality from sewage treatment works.

8. Environmental Management: Soil Management
To salvage and protect available soil resources.
Soil stockpile are stored according to the EMP.

9. Environmental Management: Protection Of Biodiversity
All staff and contractors are encouraged to report sightings of animals that enter operational areas so they can be relocated to avoid danger and harm.
Primary and secondary game fencing in and around mining and processing areas.
A seed and weed inspection system was developed and currently implemented to prevent the proliferation of alien invasive species.

10. Environmental Management: Ambient Noise Monitoring
Monitor ambient noise levels
Independent contractor comes on site for yearly tests.
WMN ensures that our operations minimise noise generation.

11. Environmental Management: Waste Management
To prevent the contamination of soils and water resources due to inappropriate management and disposal of waste.
Waste generated is separated at source into general waste and hazardous waste.
Contractors manage their own waste. However, WMN oversees overall effective implementation of waste management onsite.
General Waste
General waste is disposed at the Tsumeb general waste landfill site.
Hazardous Waste
Hazardous waste is disposed at a hazardous waste disposal site.

12. Environmental Management: Ambient Air Quality Monitoring
An air quality monitoring programme is comprised of:
Total suspended particulate evaluation by dust fallout sample collection at nine locations (i.e., dust bucket samplers)
PM10 particulate evaluation by mini-vol sample collection at one location.
The programme is put in place to monitor the effectiveness of dust management during operations and implement improvements as required.
Surface wetting is out on in-pit roads, drilling, crushers and at materials handling points.
PM10
Dust fallout
Sampled every 6 days.
Dust fallout monitoring is carried out every 30 days at all the 9 locations as per SANS Guidelines .

18. Challenges Lack of recycling facilities in the Tsumeb area.
Pit dewatering
Currently using diesel driven pumps inside the pit.
Plan is to lower the pit water levels by means of electrical pumps outside of the pit.
Anti-poaching

19. Successes Environmental Forum Stakeholders Involvement
Progressive Rehabilitation
Pit Dewatering
Recycling Initiatives i.e. Paper & Used oil
Positive feedback from external Auditors on our annual compliance audits
