PT Vale has started planning a mine closure that is still a decade away, and the early start is where the value sits

A consultation held a decade before the ground is handed back

PT Vale Indonesia Tbk, through its Indonesia Growth Project (IGP) in Morowali, Central Sulawesi, has begun drawing up the post-mining plan for Bahodopi Blocks 2 and 3. The plan covers the years 2036 to 2040. ANTARA reported the work on 19 September 2026, following an open stakeholder consultation held at Hotel Metro in Desa Bente, Kecamatan Bungku Tengah, Morowali. Local outlets in Central Sulawesi date the consultation itself to Friday 18 September, while the national wire datelines its account to Saturday. The account of what was discussed is consistent across both.

The gap between the plan and the event it plans for is the story. Mining at Bahodopi Blocks 2 and 3 is expected to continue for roughly another decade. Indonesian practice has more often treated closure as a document produced near the end of a permit, when options have narrowed and costs have hardened. Starting the conversation now, with regulators, district officials and village representatives in the room, changes the character of the exercise.

"We are aware that mining activity has a cycle. That is why, from an early stage, we have begun drawing up the post-mining plan for Bahodopi Blocks 2 and 3 for the years 2036 to 2040." Muharam Zamzam, Head of Permit at PT Vale, speaking in Morowali.

Muharam framed the consultation as a matter of running a responsible, transparent and sustainable operation rather than as a compliance filing. He described the plan as a shared effort, so that when mining ends the surrounding community still has a liveable environment, an economy that keeps growing, and a future worth planning for. Speaking to Sulteng Raya, he put the ambition more plainly: the company does not want to leave behind a worked-out site of no use to anyone, and intends instead to leave a positive legacy through rehabilitated land, managed water, empowered communities and working relationships that hold.

Attending agencies included the Central Sulawesi mining inspectorate, the district and provincial environment offices, the provincial energy and mineral resources office, the one-stop investment service, and forestry offices at both district and provincial level. That list matters. Post-mining land in Indonesia usually crosses several jurisdictions at once, and the cost of reconciling them rises the later they are brought together.

What the Bahodopi plan puts on the table

PT Vale set out six components. The first is land rehabilitation and revegetation, covering landform reshaping, replanting, restoration of soil fertility, and control of erosion and sedimentation, with the stated aim of leaving former mining land both productive and safe. The second is water and environmental management, with commitments on water quality and quantity, on the performance of sedimentation ponds, and on keeping environmental parameters within their standards. The company said it continues to monitor air, water and biodiversity as part of that work.

The third component is geotechnical stability and safety, so the worked area remains stable and poses no hazard to nearby communities. The fourth is social and economic empowerment, through training, small business development, agriculture and plantation programmes. The fifth is the use of assets, infrastructure and facilities that can be handed to community use in line with regulation. The sixth is synchronisation with policy and spatial planning.

Regent of Morowali Iksan Baharudin Abdul Rauf welcomed the consultation and made a specific request. He noted that post-mining is the final stage of the mining sequence and the one most often left unattended, and argued that it can instead become the basis of a durable local economy once a company stops operating in the district. He pointed to cashew and oil palm cultivation as examples of land uses that could carry benefit to residents and to the generation that follows. He asked all parties to examine the draft closely so that implementation delivers for both the environment and the local economy.

The record the commitment rests on

PT Vale has a reclamation history that can be checked. Across 2025 the company completed reclamation on 158.09 hectares, of which 156.67 hectares were at the Sorowako operation in South Sulawesi and 1.42 hectares were former construction areas at Bahodopi. It replanted 72,296 trees during the year using local, endemic and protected species.

The cumulative position has moved steadily. In its 2023 sustainability report the company put reclaimed mining land at 3,703.6 hectares, equal to 65 percent of the 5,667.7 hectares it had opened, with about 4 million trees planted over the life of the operation. Reporting in April 2025 put the Sorowako figure at 3,791 hectares. By the first quarter of 2025 the reported cumulative total stood at 3,819.64 hectares, carrying 5.10 million trees.

The Morowali project those numbers now extend to is substantial. PT Vale puts the investment in its Morowali growth project at approximately US$2 billion, with integrated port facilities and a power supply designed around low carbon operation. The Bahodopi mine entered operation in the first quarter of 2025, with reported capacity of 5.5 million wet metric tonnes of saprolite and 10.4 million wet metric tonnes of limonite a year. Published descriptions of the associated processing capacity vary between roughly 60,000 and 73,000 tonnes of nickel a year depending on the source and the project stage described, and that range is worth treating as unsettled rather than resolved.

Closure planning is a valuation exercise before it is an engineering one

Indonesia's current rules make the financial shape of closure explicit. Kepmen ESDM No. 344.K/MB.01/MEM.B/2025, in force since 23 October 2025, sets national standards for reclamation and post-mining on land and at sea. Post-mining guarantees are placed annually and must reach 100 percent no later than two years before a permit expires. Post-mining work must be completed within five years of a permit ending, extendable once by three years. Guarantee funds are released in stages once a minimum success rate of 60 percent is demonstrated. For applications to reopen previously reclaimed ground, the rule requires an environmental economic valuation that monetises standing timber and ecosystem services such as erosion control, oxygen production and carbon sequestration, and that shows a positive cost benefit result.

Read together, those provisions describe a market in priced environmental outcomes rather than a paperwork regime. A guarantee that must be fully funded two years before permit expiry is a cash flow question that starts many years earlier. A success rate threshold of 60 percent is a measurement question that depends on baseline data collected while the mine is still running. An environmental economic valuation that monetises ecosystem services needs a defensible starting condition for water, soil, vegetation and biodiversity.

This is precisely why the timing of the Bahodopi consultation carries more weight than its content. The air, water and biodiversity monitoring PT Vale says it maintains is the raw material of a later valuation. Collected now, it is ordinary operating data. Reconstructed at closure, the same information becomes expensive, contested and weaker in front of a regulator or a court.

Sirkularium's view

For government and public institutions, the useful lesson from Morowali is procedural rather than promotional. Closure planning that begins a decade early gives regulators something they rarely have, which is time to negotiate land use, spatial planning and community programmes while the operator still has revenue, equipment and staff on site. Provincial and district agencies can use that window to agree what success will be measured against, rather than arriving at the measurement argument after the equipment has left.

Three things are worth watching. The first is whether the Bahodopi plan attaches monetary values to its environmental targets, or stops at hectares and species counts. The second is whether the post-mining guarantee schedule is published in a form district governments can track, since a guarantee funded in full and on time is the clearest single indicator that closure is real. The third is whether cashew, oil palm and the other post-mining land uses raised by the Regent are tested against an actual land capability and market assessment before they are written into a plan.

Closure is the one stage of a mine that every party can still design. What it is worth depends on what was measured while the mine was working.

Sirkularium's consistent position is that rigorous, independently verified economic valuation belongs in the operating routine of a mine rather than in its crisis response. Combining remote sensing and geographic information systems with ground measurement, applied against the methodology Indonesian regulation already recognises, produces a defensible figure for what land and ecosystem condition are worth at any point in a mine's life. Operators holding that evidence can demonstrate compliance to the Ministry of Environment and to mining inspectors without improvisation. Governments that require it can plan post-mining regional economies on figures rather than intentions. PT Vale has opened a decade-long window at Bahodopi. The value of that window depends on what gets measured inside it.
