Empowering Tanzania's artisanal and small‑scale gold mining community.

We help artisanal gold miners in emerging economies transition to mercury-free processing

Safe

Modern gold processing keep lakes, rivers, and oceans mercury-free, preventing mercury toxicity in people.

Efficient

Our modern processing techniques capture +80% of the gold in a given ore sample, more than double the 30% capture of mercury processing methods.

Verified

All gold purchased through Mwamba can be traced to its origin in the Lake Victoria Gold Fields of Northern Tanzania.

Our modern gold processing operations eliminate the use of mercury

We are buiding a network of artisanal and small-scale mining communities in rural Tanzania. We process our partners’ gold using clean and efficient Carbon in Pulp infrastructure.

How it works»

“We know mercury is inefficient, we know it is harmful, but we have no alternative. Mwamba is giving us the opportunity to build ourselves a better future. ”

Bayi Nhonoli, Gold Miner from Ngeza, Tanzania

Bayi is a MWAMBA advocate, helping us to pass a no child-labour & no-mercury agreement with Ngeza town council. In return, Mwamba has agreed to process all of the Ngeza miners' ore.

Artisanal and small-scale gold mining is the world’s largest source of mercury pollution

the mercury problem»

15 million+ miners

number of small scale gold miners in over 70 countries, including 4-5 million women and children
1400+ tons of mercury

are released into the environment through traditional artisanal small-scale gold mining each year
100% reduction in mercury processing

our impact goal for our partner communities in Tanzania

Mwamba’s model

Mercury negative

Mining communities formerly using traditional toxic mercury processing are now mercury free because of Mwamba’s efforts.
Conflict free

Gold does not come from a conflict zone where it’s sale would perpetuate war. We follow the World Gold Council's Conflict-Free Gold Standard.
Responsibly sourced

Mwamba gold is produced and sourced in a way that respects people and the environment.
Fair prices for miners

Miners receive as much as a 200% increase in payment by partnering with Mwamba.

Gold that makes a difference

We transition Tanzanian mining communities to mercury-free processing, reinvesting profits to improve working and living conditions for those involved.
