Mineral Rights: Where Contract Law Meets Natural Resources
Mineral rights — the contractual right to explore for, extract, and sell minerals, oil, gas, or other subsurface resources — occupy an unusual position in intangible asset classification. The resources themselves are tangible; the right to extract them is intangible. Under IFRS 3, mineral rights are classified as contract-based intangible assets because they arise from government-granted concessions, leases, or contractual arrangements with landowners.
In extractive industry acquisitions, mineral rights can represent the dominant asset — the right to access proven reserves is worth far more than the physical infrastructure used to extract them. Valuation requires combining geological assessment (what is in the ground) with legal analysis (what the right permits) and economic modelling (what the extracted resources are worth).

The Intangible/Tangible Distinction
In extractive industries, the boundary between intangible and tangible assets is particularly nuanced:
| Asset |
Classification |
Basis |
| Mineral right / concession |
Intangible (contract-based) |
Contractual right to explore and extract |
| Proved reserves (in the ground) |
Tangible asset |
Physical resource with measurable quantity |
| Exploration data and geological models |
Intangible (technology-based) |
Know-how and proprietary data |
| Extraction infrastructure |
Tangible (PP&E) |
Physical equipment and facilities |
| Environmental rehabilitation obligation |
Liability |
Contractual or regulatory obligation |
★ Key Takeaway
The mineral right is the licence to extract; the reserves are what is extracted. In a PPA, both must be identified and valued, but the mineral right — being contractual and finite in duration — is classified as an intangible asset, while the reserves may be classified differently depending on the accounting framework and the entity's approach.
Valuation Using the Income Approach
Mineral rights are valued by estimating the future economic benefit from extraction and sale of the underlying resources:
Assess the resource base
Determine proved and probable reserves accessible under the mineral right. This requires geological assessment and independent reserve reports (typically classified under PRMS or JORC standards).
Project extraction volumes and timing
Model the extraction profile: annual production volumes, ramp-up period, plateau production, and decline curves. The profile depends on the resource type, extraction method, and infrastructure capacity.
Apply commodity price forecasts
Use forward curve pricing for near-term periods and long-term consensus forecasts for later years. Apply a risk premium for commodity price uncertainty.
Deduct extraction and operating costs
Subtract all-in sustaining costs (AISC), capital expenditure, royalties payable to government or landowners, and environmental rehabilitation costs.
Discount Rate Considerations
Mineral rights carry several unique risk factors that affect the discount rate:
- Commodity price risk — prices can be highly volatile (oil, copper, lithium)
- Geological risk — reserves may prove less than estimated
- Regulatory risk — governments can change concession terms, impose new taxes, or revoke rights
- Political risk — for mineral rights in emerging markets, country risk is significant
- Environmental risk — changing regulations may increase extraction costs or restrict operations
Discount rates for mineral rights typically range from 10-20%, with higher rates for early-stage exploration and lower rates for mature, producing assets with proved reserves.
✔ Example
A mining company is acquired with a copper concession granting extraction rights for 25 years. Proved reserves: 500,000 tonnes of copper. Projected annual production: 25,000 tonnes at an all-in sustaining cost of $5,500 per tonne. Current copper price: $9,000 per tonne. Using a 15% discount rate and conservative commodity price assumptions, the mineral right is valued at approximately $420 million — representing the present value of the extraction profit over the concession term.
Concession Terms and Renewal
Mineral rights are defined by their concession agreements, which specify:
| Term |
Description |
Valuation Impact |
| Duration |
Concession period (typically 10-50 years) |
Sets the maximum useful life |
| Royalty obligations |
Payments to government or landowner |
Reduces net cash flow |
| Production commitments |
Minimum extraction requirements |
Creates obligation risk |
| Environmental conditions |
Restoration and rehabilitation obligations |
Reduces net value |
| Renewal provisions |
Rights to extend the concession |
May extend useful life beyond initial term |
| Reversion clauses |
What happens to infrastructure at expiry |
Affects terminal value |
⚠ Warning
Mineral rights in jurisdictions with weak rule of law carry significant expropriation risk. Historical precedent — government seizure of mining assets in Venezuela, Bolivia, and Zimbabwe, among others — demonstrates that contractual rights can be overridden by political decisions. The valuation must incorporate country risk and the specific political environment.
IFRS 6 and Exploration Assets
IFRS 6 (Exploration for and Evaluation of Mineral Resources) provides specific guidance for exploration and evaluation expenditures, which interact with the IFRS 3 treatment of mineral rights acquired in a business combination.
Key interactions:
- Exploration-stage rights — rights covering unexplored territory have value primarily based on geological potential, making them more speculative and harder to value
- Development-stage rights — rights covering resources under active development combine intangible right value with tangible development asset value
- Production-stage rights — the most straightforward to value because extraction is underway and production data provides reliable inputs
The Energy Transition Dimension
The global energy transition creates both risk and opportunity for mineral rights valuations. Fossil fuel mineral rights (oil, gas, coal) face long-term demand decline and potential stranded asset risk. Conversely, rights covering critical minerals for the energy transition — lithium, cobalt, nickel, rare earths — are appreciating as demand for batteries, renewable energy, and electrification grows. Valuation assumptions must reflect the specific mineral's position in the energy transition.
Mineral rights are one of eight contract-based intangible assets under IFRS 3. For the full classification, see 35 types of intangible assets. To explore valuation methods in detail, read our guide to intangible asset valuation methods.
