Sustaining the Tinkisso

Gold recovery without chemicals sediment reject deposited 300m from river banks Shared river stewardship

The Tinkisso River sustains agriculture, fisheries, transport, and cultural life across central Guinea before joining the Niger. West African Dredging (WAD SA) recognises that our long-term success depends on preserving this waterway’s health.

Utilizing gravity-based separation and milling techniques, we achieve environmentally responsible ‘green gold’ extraction. This method ensures high efficiency and minimal environmental impact, preserving the integrity of natural ecosystems while producing pure gold.

Every operational choice—from dredger design to workforce scheduling—therefore aligns with one clear objective: keep the Tinkisso flowing clean, stable, and life-giving for generations.

Our three sustainability pillars

Clean Water

Twin decantation basins settle fines; treated water returns to the river crystal-clear and within national turbidity limits.

Safe sediment

All tailings are pumped through 300 m pipelines to inland deposition sites that are rehabilitated with native vegetation.

Living biodiversity

Hippo-corridor monitoring, riparian tree nurseries, and community-led wildlife patrols protect habitats and prevent bank erosion.

How we deliver

Responsible Dredging

Variable-speed, low-turbidity pumps and GPS-guided cutterheads minimise riverbed disturbance, while operators halt work during peak fish-spawning periods agreed with village councils.

Water-Quality Assurance

Sediment-laden water first settles in primary basins, then passes reed-planted polishing ponds before re-entering the Tinkisso. Monthly lab tests show suspended-solid levels consistently below 25 mg L⁻¹.

Reforestation & Wildlife

A nursery at Banfara raises 5,000 native saplings annually. Planted along reshaped sediment sites, they stabilise soil and extend shaded hippo corridors mapped with community scouts.

Community Co-management

Village elders, women’s groups, and youth representatives sit on a joint sustainability committee that reviews dredging timetables, road upkeep, and biodiversity budgets, ensuring shared priorities guide every decision.

Ready for production

WAD SA has installed its dredgers and recovery plant. The camp sites are ready. The workers have been trained. Once we receive the green light from the government, we are ready to start!
