Montenegro’s Ministry of Energy and Mining has selected MIH Metal Development as the preferred bidder for a new concession covering the Šuplja Stijena zinc and lead mining district near Pljevlja, after rejecting the other two offers for administrative and eligibility defects.
The winning consortium received 100 points for its technical proposal and was ranked first on 7 August. It comprises MIH GmbH of Horstmar, Germany, as lead member, BH Holding and Kamena Dolina of Sarajevo, and Duemo Ltd of Nicosia.
The decision puts MIH Metal Development in line to replace Gradir Montenegro, whose existing concession expires on 1 January 2027. It does not yet constitute a signed concession contract. Competing bidders have 15 days from receipt of the decision to appeal to Montenegro’s Concessions Commission, and any timely appeal would suspend further steps until the challenge is resolved.
Before signing, the ministry must also verify that every member of the preferred consortium continues to satisfy the statutory eligibility requirements. The transition timetable is therefore tight: Montenegro has less than five months before the existing concession expires, while the tender outcome remains open to legal challenge and final due diligence.
Only one of the three bids reached technical evaluation
All three offers were submitted before the 31 July 2026 deadline, but only MIH Metal Development passed the initial documentation and eligibility review.
The first rejected offer came from a consortium led by Turkish construction group IC İçtaş İnşaat Sanayi ve Ticaret, together with Tethys Teknoloji İnovasyon Danışmanlık ve Ticaret and Global Industrial Solutions of Bijelo Polje.
The commission found that Global Industrial Solutions had not supplied confirmation from the relevant local authority that its municipal taxes and contributions had been paid. The consortium also failed to provide evidence that the company’s executive or responsible person had no outstanding obligations arising from penalties in misdemeanour proceedings.
The offer was additionally rejected because its documents were not bound in the prescribed manner. The tender rules required the submission to be secured so that individual pages or sections could not subsequently be inserted, removed or replaced.
Gradir Montenegro, the current mine operator, submitted the second unsuccessful bid. Its documentation did not include a Ministry of Justice certificate—or an accepted equivalent declaration—confirming that board chairman Andrzej Szary, listed as a legal representative of the company, had no relevant criminal convictions.
Gradir’s bid also failed the physical-document binding requirement.
The commission determined that each omission was independently sufficient to disqualify an offer. Missing eligibility evidence could not be supplied after the deadline because the concession rules permit clarification of technical and financial content but do not allow bidders to add documents that should have formed part of the original eligibility package.
This procedural distinction matters for investors. MIH Metal Development did not defeat two fully evaluated competing mine plans on economic terms. It became the only bidder to reach technical assessment after the other submissions failed mandatory compliance checks.
Its 100-point score confirms that its technical offer satisfied the published criteria. It does not reveal how its investment, production or concession-fee proposals would have compared with those of Gradir or the IC İçtaş consortium had all three offers remained valid.
The concession covers four deposits and 17.14mn tonnes of geological reserves
The tender covers detailed geological exploration and extraction of zinc and lead at Šuplja Stijena, Đurđeve Vode, Paljevine and Ribnik, within the Ljubišnja mining district of the Pljevlja municipality.
The concession area extends across approximately 610 hectares. Official documentation attributes roughly 17.14mn tonnes of geological reserves to the four deposits, with Šuplja Stijena and Đurđeve Vode accounting for about 15.6mn tonnes.
That resource base provides a substantial starting point but should not be treated as a bankable mining reserve. Further drilling, modelling, geotechnical work and metallurgical testing will be required, particularly at depth beneath Šuplja Stijena and at the less-developed Ribnik deposit.
At a notional processing rate of 600,000 tonnes a year, the disclosed geological inventory would correspond to more than 28 years of gross ore supply before allowing for mining losses, dilution, reserve conversion or differences in economic cut-off grades. The actual mine life will depend on the quantity that can be converted into recoverable reserves and processed at a profit.
Zinc and lead grades are as important as tonnage. Historical production demonstrates the presence of commercially recoverable mineralisation, but future economics will depend on the grade profile of the remaining ore, strip ratios, recovery rates and concentrate quality.
Silver associated with the lead concentrate can provide useful by-product revenue. Copper and other elements may also be present in parts of the polymetallic system, although they should not be assigned material value until recoveries and payable terms are established.
Šuplja Stijena is an operating district rather than a greenfield prospect
Mining at Šuplja Stijena began in 1954 and continued until 1987, when the original operation closed. During that period, the mine processed approximately 3.95mn tonnes of ore grading an average of about 1.72 per cent lead and 4.73 per cent zinc.
Historical output included roughly 76,700 tonnes of lead concentrate and 299,900 tonnes of zinc concentrate. A later open-pit campaign between 1996 and 2000 extracted another 283,000 tonnes before operations stopped again.
Gradir acquired the insolvent mine in 2006 and restarted production in 2010. Polish zinc producer ZGH Bolesław subsequently took control of the operator.
Between 2010 and 2024, Gradir extracted approximately 7.25mn tonnes of ore and produced about 171,000 tonnes of selective zinc concentrate, 47,000 tonnes of lead concentrate containing silver and 36,000 tonnes of combined concentrate.
The existing mine, processing plant, roads, power connection, tailings facilities and workforce reduce some of the capital intensity associated with a completely new development. A new concessionaire could potentially continue using or modernising this infrastructure, subject to asset ownership, technical condition and the terms agreed during the transition.
That qualification is important. Awarding mineral rights does not automatically transfer every movable and fixed asset required to operate the mine. MIH Metal Development and Gradir may need to negotiate equipment, inventories, processing facilities, employee arrangements, environmental liabilities and site access.
If those matters are not resolved before the existing concession expires, production could be interrupted even if the new mineral-rights contract is signed on time.
Gradir’s exclusion creates an unusually difficult transition
The rejection of Gradir’s offer is particularly consequential because it is not simply another unsuccessful investor. It is the incumbent operator with more than 15 years of recent production history, an established workforce and direct knowledge of the orebody and processing circuit.
A new concessionaire must obtain access to operational records, geological databases, mine plans, environmental monitoring results and maintenance information. The completeness and legal ownership of those datasets can affect how quickly MIH Metal Development is able to prepare an updated mining plan.
The consortium will also need to determine which employees transfer, whether existing labour agreements remain applicable and how health, safety and technical responsibilities are handed over.
For the state, a competitive change of operator can create an opportunity to impose stronger investment and environmental conditions. It can also produce operational discontinuity if the incoming group requires time to assemble mining management, procure equipment or negotiate control over the processing plant.
The risk is heightened by the fact that MIH GmbH’s publicly visible core business is fibre-optic infrastructure, including network planning, civil engineering and installation across European markets. That experience may support project management and construction, but it is not a substitute for open-pit mine planning, mineral processing, tailings management or concentrate marketing.
The consortium structure may have been designed to assemble complementary financing, construction and regional capabilities. The technical identity of the future mine operator, however, has not been disclosed. Investors and lenders will want to know which member or external contractor provides the necessary mining and metallurgical experience.
The group is associated with businessman Hajriz Brčvak, who leads MIH GmbH and is also connected with BH Holding. His participation gives the consortium a recognised regional sponsor, but the mine’s bankability will depend on committed capital, technical personnel and binding operating arrangements rather than sponsorship alone.
Environmental liabilities will be central to the concession contract
Šuplja Stijena’s environmental history is likely to become one of the most important issues in the final negotiations.
In July 2025, the authorities temporarily suspended operations following an incident that contaminated the Ćehotina River. Residents of the Šula area have also raised concerns over water quality, dust, tailings management, landscape damage and the cumulative effect of decades of mining.
The new concession must distinguish between historical liabilities, obligations created by the current operator and future impacts attributable to MIH Metal Development. Without a clear baseline, the incoming company could face disputes over who is responsible for seepage, contaminated soil, old waste facilities or rehabilitation of previously disturbed land.
Lenders will require an independent environmental and social assessment before financing major mine investment. This should include the stability and capacity of tailings facilities, mine-water collection and treatment, stormwater management, acid-rock drainage risk, dust control and closure provisions.
The mine’s proximity to waterways makes water management particularly sensitive. Zinc and lead operations can produce sulphide-bearing waste whose drainage must be controlled long after extraction has stopped. A concession fee and production plan are therefore only part of the state’s economic exposure; adequate financial security for rehabilitation and post-closure treatment is equally important.
Montenegro’s progress towards European Union membership will raise expectations for environmental compliance, worker safety and public consultation. A modernised Šuplja Stijena could demonstrate that an established Balkan mine can meet stricter European standards. Another pollution incident would weaken the wider political case for developing the country’s metal resources.
The project needs a funded modernisation plan
The selection decision does not disclose the consortium’s promised capital expenditure, production schedule, employment commitments, concession payments or environmental investments.
These terms will determine whether the transaction represents a substantive recapitalisation of the mine or primarily a change in concession ownership.
The existing processing plant has supported production since the 2010 restart, but ageing mining districts require continuing investment in equipment, crushing, grinding, flotation, water treatment and tailings capacity. Deeper ore can increase haulage distances, geotechnical complexity and pumping requirements.
MIH Metal Development must decide whether to preserve output near the historical level, expand throughput or alter the mine plan to prioritise higher-margin zones. Faster extraction can improve near-term cash generation but requires more equipment and can shorten mine life. A more selective plan may preserve value but reduce employment and concession revenue in the early years.
The consortium’s financing structure is unknown. Mining debt is sensitive to zinc and lead prices, reserve confidence, concentrate offtake and environmental risk. A credible package would probably require substantial sponsor equity before commercial lenders accept exposure.
Long-term offtake could provide part of the solution. The mine has historically exported concentrates for processing abroad, including to Poland. An agreement with a creditworthy smelter or trader could support working-capital and project-finance facilities, but pricing terms would need to reflect treatment charges, transport, impurities and payable silver.
Montenegro captures employment, taxes, concession fees and local procurement from concentrate production, but most downstream refining value is realised elsewhere. The state may seek greater domestic processing over time, although a dedicated zinc or lead smelter would require much larger and more secure feed volumes than Šuplja Stijena alone may provide.
The 15-day appeal period is the immediate catalyst
The unsuccessful bidders can appeal within 15 days of receiving the decision and may inspect the tender documentation during the same period. A valid appeal would automatically halt the concession procedure.
Gradir has the strongest strategic reason to challenge the outcome because losing the concession threatens its existing mining operation and the value of infrastructure assembled under its current rights. The ministry’s decision, however, sets out multiple independent reasons for rejecting Gradir’s bid, including both missing eligibility evidence and improper binding.
The IC İçtaş-led consortium faces an even broader set of deficiencies. Any appeal would need to overcome the tender rules prohibiting post-deadline supplementation and the commission’s argument that it applied identical standards to all participants.
If no appeal is filed—or if challenges are rejected—the ministry must complete its final eligibility review and negotiate the concession agreement with MIH Metal Development. The parties will then need to organise the transfer before Gradir’s contract ends on 1 January 2027.
The selection has therefore resolved only the identity of the preferred bidder. It has not yet settled the continuity of mining, ownership of operating assets, treatment of environmental liabilities or funding of the next investment cycle.
MIH Metal Development’s 100-point result gives the consortium a legal lead, but its commercial test begins after the tender. It must convert a concession award won largely through procedural compliance into a funded, technically credible and environmentally controlled mining operation—while managing the departure of an incumbent that remains central to the mine’s current production system.
