DRC mining code explained for investors and operators

The DRC Mining Code — formally Loi n° 18/001 du 09 mars 2018, a revision of the 2002 Code — governs all mining rights, fiscal obligations, environmental requirements, and community obligations applicable to mineral extraction in the Democratic Republic of Congo. It is the primary legal document any investor, operator, or offtake buyer needs to understand before engaging with the DRC mining sector.

The 2018 revision made changes significant enough that operators who negotiated project terms under the 2002 Code found their economics materially altered. The principal modifications are: removal of the ten-year stability clause; increase in royalty rates for strategic minerals; higher minimum state equity participation; introduction of a super-profits tax; and expanded environmental and social obligations.

What changed in the revised code

The 2002 Mining Code was widely regarded as investor-friendly. It included a ten-year stability clause under which fiscal and customs terms agreed at the time of an exploitation permit could not be varied for a decade. That stability provision gave project developers and lenders confidence that royalty rates, corporate tax rates, and import duty exemptions would hold for the project's initial operating phase.

The 2018 revision removed that stability guarantee. New projects no longer benefit from it, and existing projects lost it upon the 2018 revision's promulgation. This was the change most vigorously contested by operators; several companies initiated international arbitration or formal renegotiation processes after 2018.

The 2018 Code also reclassified several minerals — cobalt, germanium, coltan, and others — as strategic substances. Strategic reclassification raised the applicable royalty rate for those minerals from 2 percent to 10 percent of ex-works value.

Equity, licences and renewal conditions

The DRC Mining Code establishes two principal permit types: the Permis de Recherche (PR) for exploration and the Permis d'Exploitation (PE) for production. Both are administered by the Cadastre Minier (CAMI), which maintains the national mining register and handles all permit applications, renewals, and transfers.

A PR is valid for five years and is renewable twice for periods of five years each, subject to minimum expenditure requirements and restitution of a portion of the permit area at each renewal. A PE is valid for thirty years from the date of issue and is renewable for successive fifteen-year periods subject to compliance with the Mining Code.

Under Article 71 of the 2018 Code, an applicant for an exploitation permit must demonstrate: technical capacity to operate the mine; financial capacity to fund construction and closure; compliance with environmental conditions, including submission of an Environmental and Social Impact Assessment (ESIA) and receipt of a Certificate Environnemental from the competent ministry; and acceptance of the 10 percent non-dilutable state equity participation in the operating company.

The 10 percent state equity is granted free of charge to the DRC government at the time the PE is issued. It cannot be diluted by subsequent capital increases. The government-side interest is typically held through Gécamines or a designated state vehicle depending on the sector and province.

CAMI's permit management database is publicly accessible at cadastreminier.cd and allows query by permit holder, province, commodity, and expiry date. The database is updated periodically; formal verification of current permit status requires a notarised extract.

Royalties and fiscal rules

Royalty rates under the 2018 Code are applied to the ex-works value — the declared price at the mine gate, less transport, insurance, and refining charges to that point. Rates by mineral class as of April 2026:

Copper: 3.5 percent Cobalt (strategic): 10 percent Gold: 3.5 percent Coltan (strategic): 10 percent Cassiterite: 3.5 percent Wolframite: 3.5 percent Zinc: 3.5 percent Germanium (strategic): 10 percent Diamonds: 6 percent

The super-profits tax mechanism — governed by Article 251 of the 2018 Code — applies when the realised commodity price exceeds the feasibility-study price by more than 25 percent. The additional tax rate in that event is 50 percent of the excess profit above the threshold. The practical application of Article 251 requires annual reconciliation with the Direction Générale des Impôts (DGI), and the calculation methodology has been a source of dispute between operators and the government.

Article 71

Article 71 is the provision most frequently cited in project-level negotiations because it establishes the conditions a company must satisfy to convert an exploration permit into an exploitation permit. It requires, in summary: proof of technical and financial competency; a validated ESIA; acceptance of the 10 percent free-carried state equity; submission of a feasibility study; and confirmation of a social and community plan (Plan de Développement Communautaire).

Failure to satisfy these conditions at the application stage will result in permit refusal. Delays in ESIA approval — which requires sign-off from the Agence Congolaise de l'Environnement (ACE) — have historically been a source of project timeline slippage.

Article 241

Article 241 establishes the formula for royalty calculation and confirms the ex-works pricing basis. It also specifies the applicable royalty rate for each mineral class, cross-referencing the strategic-substance designation list. Changes to the strategic-substance list or the applicable royalty rate require a regulatory amendment rather than a full legislative revision, which means the government has a faster pathway to rate adjustments than a standard Code amendment would imply.

Certificate environnemental

The environmental certificate (Certificat Environnemental) is a prerequisite for the issuance of an exploitation permit. It is granted by the Ministry of the Environment on the basis of a completed and approved ESIA and an Environmental Management Plan (Plan de Gestion Environnementale et Sociale, PGES). The certificate must be obtained before CAMI can formally issue the PE.

In practice, the ESIA and certificate process takes between twelve and thirty-six months depending on project complexity, the completeness of baseline environmental data, and the pace of ministry review. Operators who have failed to budget adequate time and resources for this step have experienced significant project delays.

Environmental and community obligations

Beyond the certificate, the 2018 Code requires operators to establish an environmental rehabilitation fund, calculated as a percentage of total project capital expenditure, to cover mine closure and site rehabilitation. Contributions are made annually from the start of production.

Social obligations include the Plan de Développement Communautaire, an annual community development programme funded at a specified percentage of project revenue, and the Cahier des Charges — a contract between the operator, the relevant decentralised territorial entity (Entité Territoriale Décentralisée, ETD), and the provincial government that specifies the operator's local development obligations.
