Likely toxicity to manage: hexavalent chromium, nickel, manganese dust, iron.
- • Indian mustard (Brassica juncea) – Cr accumulator
- • Sunflower (Helianthus annuus) – metal uptake, harvest and dispose
- • Vetiver grass
- • Rhodes grass
- • Weeping lovegrass
- • Sweet thorn (Vachellia karroo)
- • Kalahari sour grass (Schmidtia pappophoroides) – dry areas
- • Dam: line or check the liner, plant reed beds on inflows to trap metals and sediment.
- • Excavation / pit: reshape walls to safe slopes, return stored topsoil, let water settle as a wetland with reeds or backfill.
- • Waste rock: cap with 30 cm topsoil, contour berms, plant grasses then pioneer trees.
- • Plant / processing: dust suppression, tree windbreak rows downwind.
- • Rehabilitated area: monitor cover each season; reseed bare patches.

- Tests still needed
- tailings pH, metals (XRF/ICP), EC, sulphate, water quality
Metal-absorbing plants (mustard, sunflower) must be harvested and disposed of safely, never eaten or fed to animals. Confirm species with a tailings chemistry test.
Compliance evidence checklist
| Obligation | Authority | Evidence status |
|---|---|---|
| Mining right / permit | DMRE | |
| Environmental Authorisation + EMPr | DMRE / DFFE | |
| Rehabilitation & closure financial provision | DMRE | |
| Mine health & safety (MHSA) | DMRE / MHSC |
Status tracks EVIDENCE, not an automatic verdict: "evidence missing" or "self-declared" is NOT the same as non-compliant. Only a recorded adverse finding is a failure — and it stays visible regardless of the overall picture. Statutory status comes only from recorded authorisations.
Funding scenarios

Unquoted planning scenarios — each needs its own scope, dated quotations, eligibility and approval before any figure is real. SEPARATE from the legal closure financial provision, which is a statutory obligation, not development funding.
