Senegalese President Bassirou Diomaye Faye signed Décret n° 2024-1502 on 31 July 2024, suspending all artisanal and industrial mining operations and barring the issuance of new mining exploration and exploitation titles within a 500-metre corridor along the left bank of the Faleme River until 30 June 2027. The measure was adopted in Council of Ministers on 18 July 2024 following a ministerial mission to the zone in May 2024, and is motivated by severe environmental degradation, public-health risks from mercury and sediment contamination, and border-security concerns along the Senegal-Mali boundary in the OMVS basin.

Mechanism

Décret n° 2024-1502 establishes a three-year exclusion zone along the left bank of the Faleme River — the Senegal-Mali border watercourse draining roughly 23,000 km² of the Organisation pour la Mise en Valeur du fleuve Sénégal (OMVS) basin. The decree:

1. Suspends all artisanal gold-mining (orpaillage) operations within 500 m of the left bank for the duration until 30 June 2027. 2. Bans issuance of new mining titles (exploration and exploitation permits) in the same perimeter, blocking new entrants during the suspension period. 3. Mandates enforcement coordination across the ministries of Energy/Mines, Armed Forces, Environment, Labour, and Education — a multi-ministry mission had visited the zone on 26–27 May 2024 and documented the contamination crisis.

The primary driver was documented mercury contamination from artisanal gold processing and the near-total destruction of riverbank vegetation, causing cross-border pollution that reached Mali and Guinea downstream. Border-security dimensions were cited separately: the Faleme corridor has been a locus of unregulated cross-border mineral flows and associated informal economic networks.

Downstream implications

Cross-border gold flows: The suspension directly constrains informal and semi-formal gold production in one of Senegal's highest-density artisanal-mining zones. Displacement to non-restricted Senegalese sites or across the border into Mali is probable (as enforcement challenges reported in September 2024 suggest).
Title pipeline freeze: No new exploration or exploitation licences may be granted in the perimeter through June 2027, disrupting junior mining companies' timeline for advancing Faleme basin projects.
OMVS multilateral signal: Environmental commentators and OMVS civil society bodies framed this as a precedent-setting sovereign regulatory act that peer OMVS states (Mali, Guinea, Mauritania) were being implicitly invited to replicate along their own Faleme banks — a signal for transboundary basin governance rather than purely a domestic action.
Senegal resource governance trajectory: Filed alongside 2019-02-01-senegal-loi-2019-04-contenu-local-hydrocarbures (local-content statute for hydrocarbons) and 2026-03-12-senegal-primature-petroleum-mining-contract-renegotiation (contract-renegotiation programme), this decree completes a cluster of early Faye-administration resource sovereignty actions spanning the petroleum, mining, and artisanal-mining sectors.

Open questions

Whether President Faye will extend the suspension beyond June 2027 if river-quality remediation is incomplete.
Whether Mali, Guinea, or Mauritania enact parallel exclusion zones on their own Faleme banks in response to OMVS civil-society pressure.
Enforcement efficacy: September 2024 reporting confirmed persistent violations, with security forces seizing equipment but unable to halt the activity entirely.
