Sibanye-Stillwater, the multinational mining and metals giant entangled in a major legal battle with Appian Capital Advisory. This case stems from a deal worth $1.2 billion that was abruptly terminated in January 2022.
The ongoing proceedings, which are being heard in the High Court of England and Wales, revolve around the acquisition of two Brazilian mines: Santa Rita, a nickel mine, and Serrote, a copper mine. Notably, the former is one of the rare nickel sulfide mines that is still operating. It also produces copper, cobalt, and platinum group metals as by-products.
Sibanye’s decision to withdraw from the deal has led to accusations and legal claims for compensation by Appian. As both sides prepare for the next phase of the case in November 2025, the stakes are high, with claims that could exceed $600 million, as reported by MINING.COM
The Massive $1.2B Deal and Its Collapse
Going back in time, in October 2021, Sibanye-Stillwater struck a $1.2 billion deal with Appian to acquire the Santa Rita and Serrote mines. These assets are owned by Atlantic Nickel and Mineração Vale Verde. Appian’s funds were meant to strengthen Sibanye’s stock of critical metals. The latter was looking to shift its focus from platinum and gold to new opportunities.
Notably, Sibanye-Stillwater had robust plans to expand into battery metals like nickel and copper which are the most essential for the fast-growing electric vehicle (EV) market.
However, just three months later, Sibanye-Stillwater terminated the share purchase agreements (SPAs), citing a “geotechnical event” at the Santa Rita mine as the primary reason. The mining company cited the event as significantly impacting future operations and used it to justify backing out of the deal. Appian, however, claimed that the event was minor and did not justify the termination of the agreements, leading to the start of legal proceedings in 2022.
The Legal Battle and Initial Rulings
The first stage of the legal battle began in June 2024 and centered on whether the geotechnical event could be reasonably expected to have a material and adverse impact on Santa Rita’s operations. After a five-week trial, Justice Butcher ruled in October 2024 that Sibanye was not justified in terminating the SPAs.
The press release revealed that, according to the judgment, the geotechnical event at Santa Rita was neither as material nor as adverse as Sibanye claimed, meaning the company had no right to withdraw from the deal based on this event.
However, Sibanye achieved a partial victory in the ruling. The court dismissed Appian’s claim of “wilful misconduct”, with the judge acknowledging that Sibanye’s management genuinely believed they were acting in the company’s best interest. This ruling suggests that while Sibanye’s reasoning was flawed, the company did not act with malicious intent.
Appian’s Compensation Claims and Initiation of the Quantum Trial
Appian is now pursuing compensation for the failed deal. The company initially sought $522 million in damages but has indicated that the total claim could exceed $600 million, including interest and legal costs. These figures represent the difference between the agreed purchase price and the mines’ current market value, alongside expenses incurred during the resale process.
Appian further pressed that Sibanye’s termination caused substantial financial losses, and they aimed to recover the full amount.
The legal battle is far from over, as the case now moves into the second phase—a trial scheduled for November 2025. This trial, known as the Quantum Trial, will determine the exact amount of damages Sibanye will be required to pay, if any. Appian argues that they would have sold the mines to another buyer for a similar price if the deal had not fallen through.
However, Sibanye maintains that Appian received multiple offers for the mines after the deal’s collapse and, therefore, cannot claim that they suffered a significant financial loss.
Sibanye’s position in the Quantum Trial is that Appian failed to mitigate its losses. Under English contract law, a party seeking compensation is required to take reasonable steps to reduce the damages they incur. Sibanye argues that Appian could have, and should have, sold the mines at fair market value soon after the deal was terminated. The company also asserts that Appian’s continuing ownership of the mines may have resulted in profits, which would reduce the overall damages they could claim.
High Stakes for Sibanye-Stillwater, Will Nickel Pay Off?
The legal battle with Appian comes at a difficult time for Sibanye-Stillwater. Leading media agencies reported that CEO Neal Froneman is already grappling with declining prices for platinum group metals, which has put additional pressure on the company’s financial performance.
As Sibanye seeks to diversify its portfolio and reduce its reliance on these traditional metals, the outcome of the trial could have significant implications for the company’s strategic direction.
Sibanye-Stillwater’s expansion into battery metals is a crucial part of its growth strategy. The company has made several moves in recent years to acquire assets in this sector, including its initial attempt to purchase Appian’s Brazilian mines.
However, the collapse of this deal has forced Sibanye to explore other opportunities. Analysts have noted that the prices of nickel, copper, and other battery metals have risen sharply in recent years, making it more challenging to find affordable assets.
Nickel, in particular, is increasingly important for the production of lithium-ion batteries used in electric vehicles. However, miners and market experts predict that the demand for nickel and other critical metals will certainly surge with the EV boom.
This leads to the most inevitable scrutiny- can Sibanye-Stillwater’s ability to secure access to these materials propel its growth in the battery metals market in the future?

Appian vs. Sibanye: The Final Verdict Looms
In the meantime, the Brazilian mines in question continue to operate, with Santa Rita transitioning from open-pit to underground operations. This transition to high-grade nickel can potentially extend the mine’s life by over 20 years. Alternatively, it significantly highlights the ongoing value of these assets and the high stakes involved in this legal battle.

The Strategic Case for Nature-Based Carbon Investments
Nature-based carbon investments deserve consideration when they address a specific business dependency and produce outcomes you can measure. Imagine Moonbucks, a global coffee roaster planning next season’s espresso blend. It is considering natural Grade 4 coffee from Jimma, in southwestern Oromia, Ethiopia. Its sourcing decisions affect the roasting schedule and the cash tied up in coffee purchases. Moonbucks needs to understand which measures could protect that supply, what they would cost and how it would judge the results.
1. Define the sourcing problem before choosing a project
Moonbucks needs a dependable component for its espresso blend. Its procurement team wants continuity of volume and an agreed cup profile. Replacing a shipment at short notice could require new sample approval and changes to the blend, and given the schedules for cultivation, processing, and freight delivery, is practically impossible. Moonbucks needs to get this right, and its initial concern is inconsistent deliveries. It commissions an assessment of the supplying farms and post-harvest chain. The questions cover land condition, harvest availability and whether drying or storage problems are affecting saleable lots.
This distinction changes the investment brief. A tree-planting proposal cannot be assumed to fix drying problems. Better storage cannot restore eroded land. The team must establish which problem exists before selecting the response.
CCC’s guide to finding nature-based solutions in your supply chain explains where to look. Here, the next task is to turn a broad concern into a testable proposal.
2. Develop nature-based carbon investments around the actual supply chain
The assessment would trace Moonbucks’ purchases back through the exporter and supplying producer groups. Which farms supply the contracted lots? Who controls land-management decisions? How long does the buyer expect to maintain the purchasing relationship?
Furthermore, Jimma natural Grade 4 cannot be treated as interchangeable with every Ethiopian coffee. Moonbucks would need to test any substitute against its own blend and quality requirements.
Suppose Moonbucks’ assessment identifies an opportunity to maintain shade trees and restore vegetation along exposed streambanks. The IPCC describes agroforestry as a way to store carbon in vegetation and soil, with potential benefits for erosion control and water quality.1 Moonbucks would need local advice on species, growing conditions and maintenance before deciding how these measures fit its sourcing plan.
The proposal now has a defined sourcing connection and a candidate intervention. The next steps are to test its effect on production, assess carbon eligibility and build the financial case.
3. Compare the proposal with other ways to protect supply
WBCSD’s Nature-based Solutions Blueprint recommends comparing nature-based options with other responses across their benefits and costs.2 For Moonbucks, that means evaluating the landscape proposal alongside drying improvements, storage controls and alternative sourcing arrangements.
The product’s natural-process designation matters. Moonbucks should examine the drying and dry-milling chain alongside land conditions. Its team would check storage practices, contamination risks and incoming-lot quality to see whether problems arise before or after the coffee leaves the farms.
The revised proposal might combine land stewardship with separate post-harvest controls. Each component needs its own purpose and budget. A sustainability label should not obscure which activity is expected to solve which problem.
The project develops as the evidence improves. Its scope should follow the diagnosis rather than preserve the first idea unchanged.
4. Establish what the carbon outcome could count toward
Moonbucks’ sustainability team now tests the proposed carbon case separately from the sourcing case. Is the objective a measurable change in Moonbucks’ value-chain emissions, verified credits for separate voluntary use, or distinct outcomes under carefully defined arrangements?
Scope 3 covers value-chain emissions. A purchasing relationship alone does not prove that a farm intervention can be included in Moonbucks’ inventory. The team needs an applicable accounting method, defensible boundaries and evidence supporting attribution.
SBTi’s FLAG Guidance (forest, land and agriculture), version 1.2, says purchased credits used as offsets cannot meet near-term FLAG or energy and industry targets. Eligible land-based removals are subject to accounting requirements.3 Moonbucks needs to test its proposal against those rules before including an outcome in its targets.
For Moonbucks’ Jimma proposal, maintaining existing trees and establishing new vegetation could involve different carbon questions. Specialists must examine the baseline and additionality, meaning what changes because the project proceeds. They must also assess measurement and the risk that stored carbon is lost. CCC’s MRV and additionality article introduces those tests.
Until that work is complete, Moonbucks should not budget an assumed Scope 3 reduction or credit-sale receipt. Direct emissions reductions remain the priority.
5. Build a financial case that survives weaker assumptions
Moonbucks’ finance team would now build a multi-year budget. UNEP’s State of Finance for Nature 2023 compares current finance with the investment needed to meet climate, biodiversity and land-restoration goals.4 The company would cost its proposed activities, farmer participation and ongoing monitoring. Verification, where required, is a separate expense. Maintenance and responsibility for replacing failed plantings must remain visible after the initial establishment budget ends.
Operational benefits need equally careful treatment. If fewer rejected lots reduce emergency purchasing, count that saving once. Do not add “supply resilience” as another financial benefit when it represents the same avoided cost.
Moonbucks should compare a base case with slower benefits, higher implementation costs and no carbon revenue. It should also distinguish production outcomes from quality and shipment outcomes. A single good harvest would not prove that the landscape intervention caused better delivery performance.
A project can remain worth funding even when its carbon case needs more work. That decision must rest on the operational evidence and the company’s objectives, without unsupported environmental claims.
6. Fund a pilot with a clear expansion decision
Moonbucks’ first approval would fund a bounded pilot, rather than commit the entire sourcing program. Before spending, Moonbucks would agree on participating farms, responsibilities and the evidence needed at review.
Its scorecard could track farmer participation, implementation costs and plant survival, alongside accepted coffee volumes and lot-quality results. Carbon measurements would follow the selected method. Farm-level traceability must connect the intervention to the actual sourcing relationship.
Suppose Moonbucks’ review later finds that storage changes explain most quality improvements, while the land measures need longer observation. Those findings would shape the next decision: expand the proven component, adjust the landscape work or pause further spending. They would not justify crediting all improvements to tree planting.
This gives nature-based carbon investments a practical place in a multi-year strategy. Funding increases as the evidence supports it, and the project can change direction before a larger commitment.

EU carbon credit claims after 27 September 2026
EU carbon credit claims changed on 27 September 2026, the day the Directive (EU) 2024/825 began to apply across the European Union. The change is narrow. It changes how a company can talk about the credits it buys. A product can no longer be called neutral on the strength of compensation alone; however, every specific, evidenced statement about what a company measured, reduced, and funded stays fully available.
