Mineral Deposit Valuation

Red Flags When Buying a Mineral Deposit: 10 Things to Check

Having a valid subsoil use permit and substantial mineral reserves does not guarantee that a deposit can be developed legally, technically, or economically. Before investing, it is essential to assess not only the geology but also legal rights, land ownership and access, environmental restrictions, and the project's actual economic viability.

The term "buying a mineral deposit" is commonly used, although legally, a transaction may involve the acquisition of shares or ownership interests in a subsoil use company or the transfer of subsoil use rights under the procedure established by law. These are different legal mechanisms with different implications for the buyer. In particular, the transfer of subsoil use rights is regulated by Article 16-1 of the Subsoil Code of Ukraine.

Below are ten key factors to examine before signing an agreement and determining the final value of a mineral asset.

1. Issues with the Subsoil Use Permit

Verify the current permit holder, the authorized type of subsoil use, the permit's validity period, geographic boundaries, restrictions, and amendment history.

Red flags: suspension or risk of termination of the permit; failure to comply with the subsoil use agreement or work program; ongoing litigation; discrepancies between the asset being offered for sale and the actual boundaries of the permit.

Documents to request: the subsoil use permit and all amendments, the subsoil use agreement, the approved work program, correspondence with regulatory authorities, and evidence of compliance with permit obligations. Legal basis: Subsoil Code of Ukraine.

2. Overestimated Reliability of Mineral Reserves

A large reserve figure in a deposit passport does not reveal the level of geological confidence, reserve categories, raw material quality, or the relevance of the underlying economic assumptions. A historical classification of reserves as economically viable does not guarantee profitability under current market conditions.

Red flags: outdated geological reports without accessible primary data; unclear reserve or resource categories and classes; insufficient testing; discrepancies between geological reports, official reserve evaluation documents, and current reserve records.

Documents to request: geological exploration reports, state expert review and reserve evaluation protocols, reserve estimation materials, geological maps and cross-sections, borehole data, production records, and information on changes in reserves. Regulatory basis: Classification of Mineral Reserves and Resources of the State Subsoil Fund (Cabinet of Ministers Resolution No. 432).

3. Unresolved Land Ownership and Land Use Issues

A subsoil use permit does not automatically grant the right to use surface land for an open-pit mine, waste dumps, processing facilities, access roads, or other mining infrastructure.

Red flags: lack of land use rights for critical areas; privately owned plots within the planned mining area; incompatible designated land use; registered encumbrances; inability to secure safe and practical access.

What to check: cadastral parcel numbers, registered property rights and encumbrances, and spatial overlaps between the subsoil permit boundaries, mineral reserve boundaries, mining allotment, and planned mining footprint. Legal basis: Land Code of Ukraine and Subsoil Code of Ukraine.

4. Territorial and Environmental Restrictions

Mineral reserve boundaries may overlap with territories or zones subject to special land use and environmental protection regimes. However, proximity to a protected or restricted area does not always mean that mining is completely prohibited. The applicable restrictions must be determined based on the legal status of the specific territory and the type of planned activity.

Red flags: protected nature areas, water protection zones, coastal protection strips, utility protection zones, cultural heritage sites, and residential developments within the potential impact area.

What to check: urban planning and environmental records, registers of land use restrictions, officially established boundaries of protected or restricted territories, and the actual feasibility of locating the mine and its infrastructure. Legal basis: Law of Ukraine "On the Nature Reserve Fund of Ukraine" and Water Code of Ukraine.

5. Missing or Incomplete Permits and Project Documentation

A subsoil use permit does not replace all the documentation required to commence or continue mining operations. The applicable requirements depend on the type of mineral, mining method, and characteristics of the planned activity.

Red flags: missing mandatory Environmental Impact Assessment (EIA); inconsistencies between the approved mine development project and actual operations; missing authorizations for hazardous work; or unapproved changes to production processes.

What to check: the complete list of mandatory documents applicable to the specific deposit, the mine development project, existing EIA conclusions, required permits, and their consistency with planned operations. Legal basis: Article 3 of the Law of Ukraine "On Environmental Impact Assessment" and Mining Law of Ukraine. An EIA is mandatory for the types of planned activities specified by law, rather than automatically for every mineral deposit.

6. Challenging Mining and Geological Conditions

The commercial value of mineral reserves depends on more than the concentration of valuable components. A high stripping ratio, groundwater inflows, unstable rock formations, or significant variability in ore thickness can substantially increase operating costs.

Red flags: missing hydrogeological or geotechnical data; complex mine dewatering requirements; insufficient justification of pit slope parameters; unaccounted mining losses and dilution.

What to check: geological cross-sections, hydrogeological studies, overburden models, mining loss and dilution factors, slope stability calculations, and production cost estimates. For mining safety requirements, refer to the Mining Law of Ukraine.

7. Unverified Processing and Metallurgical Performance

The grade of a valuable mineral or component does not directly translate into the yield of marketable products. Actual project economics depend on processing efficiency, recovery rates, impurities, consistency of product quality, and customer specifications.

Red flags: absence of representative processing samples; projected product yields unsupported by testing; requirements for expensive beneficiation processes; potential price penalties due to harmful impurities.

What to check: metallurgical or mineral processing test reports, mass balance calculations, concentrate recovery and quality, specifications of final saleable products, and compliance with potential buyers' requirements. This is primarily a technical and commercial assessment rather than a formal check against a single regulatory document.

8. Infrastructure and Logistics Do Not Support the Business Plan

Distance to customers, road and bridge load restrictions, electricity grid connections, water supply requirements, and freight logistics can significantly affect a project's financial performance.

Red flags: transportation costs based on unrealistic rates; no confirmed utility connection capacity; critical dependence on a single transportation route; unaccounted investments in roads and utility infrastructure.

What to check: commercial quotations from logistics providers, utility connection conditions, seasonal accessibility, infrastructure capital expenditures, and the full cost of delivering one unit of product to the customer.

9. Financial Models Based on Overly Optimistic Assumptions

The acquisition price may represent only a portion of the total investment required. Project profitability is influenced by site preparation, overburden removal, mining equipment, mineral processing, energy, logistics, taxes, mineral extraction royalties, and land reclamation.

Red flags: financial projections based exclusively on peak commodity prices; lack of sensitivity analysis; omission of working capital requirements, project commissioning timelines, taxes, or variations in raw material quality.

What to check: capital expenditures (CAPEX), operating expenditures (OPEX), projected cash flows, sensitivity of net present value (NPV) and internal rate of return (IRR) to commodity prices, production volumes, operating costs, and project timelines, as well as applicable tax liabilities. Regulatory basis: Tax Code of Ukraine, particularly the provisions governing rental payments for subsoil use.

10. Hidden Liabilities, Legal Disputes, and Environmental Obligations

Particular attention should be paid to the legal and financial position of the company when acquiring its shares or ownership interests. Purchasing equity in a legal entity and acquiring subsoil use rights have different legal consequences. The transfer or retention of specific liabilities must be assessed separately.

Red flags: outstanding tax liabilities, asset seizures, pledges, ongoing litigation, unresolved regulatory violations, environmental contamination, and unfunded mine closure or land reclamation obligations.

What to check: financial statements, registers of encumbrances, court proceedings, environmental documentation, the condition of disturbed land, and obligations related to site restoration. Legal basis: Law of Ukraine "On Land Protection" and Subsoil Code of Ukraine.

What Should You Do Before Making an Investment Decision?

An initial due diligence assessment should answer three fundamental questions:

Can the deposit be legally developed? Legal status, land rights, restrictions, and required documentation.
What can actually be extracted and sold? Reserve reliability, mining conditions, processing technology, and market demand.
Will the project be profitable? Comprehensive financial modeling, risks, liabilities, and future obligations.

Identifying a risk does not necessarily mean abandoning the transaction. However, that risk should be reflected in the asset valuation, contractual terms, project development schedule, and investment budget.

The biggest mistake an investor can make is paying for the volume of mineral reserves without first verifying whether those reserves can actually be developed and at what cost.
