How the joint venture came about

Twiga Minerals was created in 2020 to settle a years-long standoff over unpaid taxes, an export ban on mineral concentrates and disputed valuations. The settlement gave the state a free-carried stake plus a share of economic benefits, and became the template government points to in dealings with other large investors.

The North Mara human rights record

North Mara carries the most serious community record of any East African gold mine: repeated deaths and injuries in confrontations between security forces and intruders on the mine's waste rock and tailings areas, and litigation brought in overseas courts on behalf of affected families.

Remediation commitments, an independent grievance mechanism and changes to security arrangements have all been announced. The Bulletin tracks documented incidents, not company assurances.

Bulyanhulu

Bulyanhulu is a deep underground gold mine restarted after a period on reduced operations. Its tailings history and the 1990s displacement of artisanal miners from the site remain part of the asset's unresolved record.
