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

Gold miners

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

Partnership model with equity participation for local land owners grows wealth and capacity in gold mining communities, creating inroads for value-added investment, knowledge, and technology transfer
Modern gold processing services significantly improve the safety and productivity of artisanal miners using mercury to process ore and extract gold independently
Access to modern mining technologies and investment opportunities enable miners to maximize their natural resources, eliminating liquidity barriers and accelerating the flywheel of economic development in the sector

Our operations enable local stakeholders in Tanzania's gold mining industry to maximize the value of their natural resources

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.

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

  • 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.

We are committed to furthering these UN Sustainable Development Goals through our work

Increasing income and vocational opportunity.
Lifting entire communities out of poverty.
Enabling investment in civic infrastructure.
Eliminating mercury in artisanal mining.


UDSM Mineral Resources Institute (MRI)
The Mineral Resources Institute (MRI) is a prominent academic center in the sub-Saharan region, offering robust training for middle cadre professionals in the extractive industry. Accredited by the National Council for Technical Education (NACTE), the MRI provides Competence Based Education in various Earth Science disciplines and has been operational since 1982, currently under the University of Dar es Salaam
Global Mercury Partnership
The Global Mercury Partnership is a UNEP initiative working to protect human health and the global environment from the release of mercury by reducing and, where feasible, eradicating global, anthropogenic mercury releases.
Mwamba is a private sector representative of the planetGOLD Programme Advisory Group. PlanetGOLD helps artisanal gold miners replace toxic mercury with cleaner techniques, as well as improve access to finance and facilitate the formalization of the sector.
