COASTAL AND MARINE MANAGEMENT PLAN

The objective of this CMMP is to provide the framework for:

ensuring compliance with all relevant statutory requirements;
Rex Minerals Policies and Standards;
implementing tools and practices to manage and minimise the

impact of mining activities on the coastal and marine environment;

providing details on marine monitoring responsibilities; and
maintaining an effective response mechanism to deal with issues

and complaints.

OBJECTIVES OF PLAN

STATUS OF MARINE ENVIRONMENT COASTAL AND MARINE MANAGEMENT PLAN

The upper Gulf St Vincent supports seagrass communities on sand

substrates, dominated by Posidonia, Halophila and Heterozostera species.

Rocky reefs were also recorded, consisting of rock boulders and

broken bottom reef with sparse macroalage and filter feeding communities.

Shipping out of Port Ardrossan, commercial and recreational fishing

have had an impact on the seabed and fisheries.

The baseline survey identified metals including copper, zinc, arsenic

and cobalt around the Wharf and elevated hydrocarbon concentrations in sediments off Rogues Point.

COASTAL AND MARINE MANAGEMENT PLAN STATUS OF COASTAL HABITATS

Exposed tidal flats provide important food and resting places for

migratory shorebirds and nursery areas for fish species between Pine Point and Rogues Point.

The shorelines are characterised by sand, wrack, rocks and shell grit,

and low dunes.

Vegetated sand dunes with sand stabilising plants and shrubs, with 47

coastal flora species identified.

11 species of coastal birds.
Human activities have imposed impacts evident with erosion of cliffs

and gullies, and introduced plant and marine species.

CONTROL STRATEGIES COASTAL AND MARINE MANAGEMENT PLAN

The main risks to the coastal and marine environment are from dust

deposition on the coast and seabed, and runoff water from the mine.

The risks to the coastal and marine environment are negligible but Rex

Minerals has developed a separate dust management plan (AQMP) and surface water management plan (SWMP).

MONITORING PROGRAM COASTAL AND MARINE MANAGEMENT PLAN

Annual monitoring

Annual monitoring undertaken by suitably qualified person.
Focused on coastal and marine habitats between Pine Point and Rogues Point.
Annual surveys will involve visual inspection surveys and photo-point

monitoring of cliff faces, gullies and intertidal habitats.

Annual survey of seagrass health and marine ecosystem.

Records

Species composition and density of seagrass communities.
Seagrass physical parameters such as groundcover percentage, leaf length

and biomass.

GPS referenced video transects of seabed habitats.
Visual and photographic evidence of coastal/foreshore habitats.
