Mining Incentives in Nigeria: Assessing the Investment Protection Framework
under the Nigerian Minerals and Mining Act 2007
Introduction
Mining is capital-intensive, technologically demanding and exposed to significant geological,
regulatory and market risks. For a country seeking to attract private and foreign capital into its
mineral sector, the availability of mineral resources alone is rarely sufficient. Investors also
require a predictable fiscal regime, the ability to repatriate capital, access to imported
equipment, protection of investment and mechanisms for dealing with the substantial
environmental costs associated with mining.
The Nigerian Minerals and Mining Act 2007 (“the Act”) recognised these requirements and
devoted Part III, sections 23–42, to “Mining Incentives.” The provisions cover a remarkably
broad range of incentives and institutional mechanisms, including capital allowances, customs
exemptions, foreign-exchange arrangements, tax relief, deductibility of environmental
expenditure, royalty treatment and the Solid Minerals Development Fund.
The incentive framework was clearly designed to make Nigeria’s mining sector attractive to
domestic and international investors. However, there is an important qualification for anyone
assessing the framework today: some of the incentives contained in the 2007 Act have been
overtaken, modified or rendered ineffective by subsequent legislation and the passage of time.
In particular, section 28’s tax-holiday provision has been deleted by the Nigerian Tax Act 2025,
while the five-year transitional provision in section 32 is no longer practically available to new
investors.
This article examines the principal incentives under sections 23–42, the relevant provisions of
the Nigerian Minerals and Mining Regulations 2011, and the extent to which the original
incentive framework remains relevant to mining investment in Nigeria.
- Who Qualifies for Mining Incentives?
Section 23 establishes the basic eligibility principle. It provides that persons eligible for the fiscal regime in Part III include companies or enterprises engaged in mining operations. This is significant because the incentive regime is linked to participation in the mining industry rather than being a general incentive available to every business operating in Nigeria. The practical starting point for an investor is therefore the acquisition and maintenance of an appropriate mineral title and compliance with the statutory conditions attached to that title. The 2011 Regulations reinforce this framework by requiring mineral-title holders to comply with the Act, the Regulations and applicable conditions governing their operations.
- The 95% Capital Allowance
One of the most attractive provisions of the original 2007 framework is section 24. A qualifying
mineral-title holder is entitled to a 95% capital allowance on qualifying capital expenditure
incurred in the year in which the investment is made.
The qualifying expenditure includes:
- certified exploration expenditure;
- development expenditure;
- processing expenditure;
- feasibility studies;
- sample assaying; and
- infrastructure costs, including replacement costs.
The provision also allows losses to be carried forward, subject to the statutory four-year limit
contained in the original Act. The policy objective is obvious: mining requires substantial
expenditure before commercial production begins. Allowing the investor to obtain significant
fiscal recognition for qualifying capital expenditure reduces the initial tax burden and improves
project economics. For an international investor, this is potentially significant because mining
projects commonly involve long exploration and development periods before revenue is
generated.
- Customs and Import Incentives
Section 25 provides another important investment incentive. Mining operators are granted
exemption from customs and import duties on plant, machinery, equipment and accessories
imported specifically and exclusively for mining operations.
The section also provides for:
- expatriate quotas;
- residence permits for approved expatriate personnel; and
- personal remittance quotas for expatriate personnel.
The imported equipment may subsequently be disposed of, but the applicable customs and
import duties must first be paid. The Mines Inspectorate Department is responsible for
approving the appropriate machinery, equipment and accessories and ensuring compliance. The
incentive is particularly relevant to mining projects requiring specialised equipment that may
not be readily manufactured or supplied domestically. It also demonstrates an important
feature of Nigeria’s mining policy: the legislation attempts to reduce the front-end capital cost
of establishing a mining operation.
- Foreign-Exchange Retention
Section 26 addresses another concern of international investors: access to foreign exchange.
Where a mineral-title holder earns foreign exchange from the sale of minerals, the holder may
be permitted by the Central Bank of Nigeria to retain a portion of the earnings in a foreign-exchange domiciliary account. The retained funds may be used for spare parts and other mining inputs that cannot readily be obtained without foreign currency. This provision recognises the foreign-exchange requirements of mining operations. Mining companies may have substantial
obligations denominated in foreign currency, including equipment purchases, technical services, spare parts and foreign financing.
- Free Transferability of Investment Funds
Section 27 provides an important investment-protection mechanism. Subject to the Act, a
mineral-title holder is guaranteed free transferability through the Central Bank in convertible
currency of: payments for servicing certified foreign loans obtained for mining operations; and
the remittance of foreign capital in the event of the sale or liquidation of mining operations or
an interest attributable to foreign investment. For international investors, this provision is
arguably as important as the tax incentives. An investor may be willing to accept taxation and
regulatory obligations if it can confidently recover and repatriate its capital. Section 27 therefore
addresses a fundamental component of investment security: exit and capital repatriation.
- Tax Relief: An Important Historical Incentive
Section 28 originally provided a three-year tax-relief period beginning from the date of
operation, with a possible additional two-year extension by the Minister. The extension was not
automatic. The Minister was required to consider matters including:
- the rate of expansion;
- efficiency and level of development;
- compliance with the conditions upon which the mineral title was granted; and
- training and development of Nigerian personnel.
However, this provision requires an important current-law qualification. Section 28 has been
deleted by section 197(9) of the Nigerian Tax Act 2025. Consequently, it would be misleading for
a contemporary mining-investment article to present the three-year-plus-two-year tax holiday
in section 28 as an incentive currently available to new investors.
This illustrates a broader point: Nigeria’s mining incentive framework cannot be assessed solely
by reading the 2007 Act in isolation. Investors must consider subsequent tax legislation.
- Protection under Foreign Investment Legislation
Section 29 provides that the Foreign Exchange (Monitoring and Miscellaneous Provisions) Act applies to foreign-currency investments made in respect of mineral titles. It also expressly applies the Nigerian Investment Promotion Commission Act to foreign investments made in respect of mineral titles. The provision is significant because it places mining investment within the broader Nigerian investment-protection architecture. The mining investor therefore operates within two complementary legal frameworks:
Mining legislation regulates the mineral project.
Investment legislation provides the wider framework for foreign investment.
For international investors, this interaction is important when conducting legal due diligence.
- Environmental Expenditure as a Tax-Deductible Cost
Section 30 is particularly interesting because it connects investment incentives with
environmental responsibility.
Mining companies are required to establish a tax-deductible reserve for:
- environmental protection;
- mine rehabilitation;
- reclamation; and
- mine closure.
The reserve must be certified by an independent qualified person, recorded in audited financial statements and supported by a dedicated account or trust arrangement. Tax deductibility is restricted to the actual amount incurred for reclamation. This is an important policy innovation. Rather than treating environmental protection simply as a cost imposed upon mining companies, the Act incorporates environmental expenditure into the fiscal framework. The message is clear: Responsible environmental expenditure should be recognised as part of the legitimate economics of mining. This principle is particularly relevant to contemporary ESG-oriented mining investment.
- Pension Obligations
Section 31 requires mining companies and enterprises to make tax-deductible pension contributions at the applicable rate under the then-existing Pension Reform Act. This provision is better understood as part of the broader fiscal treatment of mining companies rather than as a conventional investment incentive. It demonstrates that the Act sought to integrate mining operations into Nigeria’s wider employment and social-protection framework. However, because the provision refers to the Pension Reform Act 2004, it must be read alongside subsequent pension legislation. The current regulatory position should therefore be determined under the pension legislation presently in force which is pension reform act 2014 which is inpari materia with the provision of the repealed pension reform act 2004 except for changes in the rate of contribution which moved up a little for the employer and the employee.
- Annual Capital-Cost Indexation
Section 32 provided for annual capital-cost indexation whereby an unclaimed balance of capital costs would be increased annually by 5%. But the provision was expressly limited to mines
starting production within five years from the date of enactment of the Act. Since the Act was
enacted in 2007, this was a transitional incentive. It should therefore not be presented today as
a generally available incentive for new mining projects. This is another example of why historical
statutory incentives must be distinguished from incentives that remain legally available to
contemporary investors.
11. Royalty
Section 33 provides that minerals obtained during exploration or mining operations are liable to
royalty at rates prescribed by regulations. The Minister may reduce or waive royalty where
minerals are exported solely for analysis, experimentation or as scientific specimens, subject to
the statutory conditions. The Minister may also defer royalty payment for a specified period
with the approval of the Federal Executive Council. Royalty is therefore fundamentally different
from the tax incentives discussed above.
It represents a direct fiscal return to the State from mineral exploitation. The incentive element
lies in the statutory ability to reduce, waive or defer royalty in limited circumstances, rather
than in a general exemption from royalty. The Ministry currently publishes royalty rates
separately, including its published 2024 royalty-rate schedule.
- The Solid Minerals Development Fund
Sections 34–42 establish an institutional mechanism intended to support the development of
Nigeria’s mining sector: the Solid Minerals Development Fund (SMDF).
Section 34 provides that the Fund is to be used for purposes including:
- human and physical capacity development;
- geoscientific data gathering, storage and retrieval;
- equipping mining institutions;
- extension services to small-scale and artisanal mining operators; and
- infrastructure in mining areas.
This is an important distinction. Not every provision in sections 23–42 is an incentive that
directly reduces an individual company’s tax liability. Some are sector-development incentives.
The SMDF is intended to improve the ecosystem in which private mining investment occurs.
- Conclusion
The Nigerian Minerals and Mining Act 2007 was clearly designed to create an investment-
friendly framework for the development of Nigeria’s mineral resources. Sections 23–42 contain
a combination of direct fiscal incentives, investment protections and sector-development
mechanisms.
The most significant include:
- a 95% capital allowance for qualifying expenditure;
- customs and import-duty exemptions for qualifying mining equipment;
- expatriate and residence-related benefits;
- foreign-exchange retention arrangements;
- free transferability of specified foreign capital and loan-servicing payments;
- environmental-cost deductions;
- royalty reduction, waiver and deferral mechanisms in limited circumstances; and
- the Solid Minerals Development Fund.
The 2011 Regulations complement this framework by providing procedures and conditions for
implementing incentives and, importantly, by establishing administrative machinery for the
Solid Minerals Development Fund. Regulation 5 expressly contemplates procedures and
conditions for granting incentives provided under the Act, while Regulation 19 gives operational
effect to the Fund provisions.
Key Takeaway for Mining Investors:
Nigeria’s mining legislation provides significant investment incentives, but investors should
distinguish between incentives that remain operative, incentives that have been amended by
subsequent legislation, and transitional incentives that have expired. A proper investment
assessment should therefore examine the Mining Act, the 2011 Regulations and the current
Nigerian tax and investment legislation together.
