Petra Diamonds sidelines Finsch mine, cuts jobs

Petra Diamonds (LSE: PDL) is placing its Finsch mine into business rescue and cutting jobs across its South African operations as collapsing diamond prices and a strong rand threaten the miner’s liquidity and future. 

Finsch, which generated 34% of group revenue in fiscal 2025 and primarily produces diamonds of two carats and below, has been hit by what management described as a structural decline in prices for smaller stones. The mine’s average realized price fell to about $47 per carat in April and May from $56 per carat in the third quarter, Petra said Friday.

“We are faced with an unprecedentedly weak diamond market, due to global macro factors as well as the recent Middle East tensions,” CEO Vivek Gadodia said. “We believe that there is now a structural shift on pricing of smaller sized diamonds and therefore do not foresee a significant price appreciation for the smaller sized diamonds.”

The company has suspended capital development at Finsch, redirected equipment to support production at its main Cullinan mine and consider workforce reductions across the group. Petra, which employs more than 4,000 people, didn’t disclose how many jobs could be affected but said it had begun a consultation process with employees and unions.

Investors reacted sharply. Petra shares fell 19% in London to close at 10.7 pence apiece, extending their decline to more than 30% this year. The company’s market capitalization has shrunk to £44.3 million (US$59.6 million).

Shift to Cullinan

Although prices at the main Cullinan mine dropped to roughly $81 per carat from $109 per carat during the quarter, the operation remains central to Petra’s future strategy because of its ability to produce rare, high-value Type II diamonds that command premium prices. The company is increasing mining in areas known to host those stones and is testing productivity improvements aimed at boosting recoveries and throughput.

“Liquidity headroom is tightening, guidance remains suspended, and lenders have provided covenant waivers, while management refocuses operations on Cullinan’s higher‑value Type II stones to underpin a more resilient business,” BMO Capital Markets mining analyst Raj Ray said in a note on Friday. “Petra sees the Cullinan price reduction related primarily to product mix volatility rather than being considered a structural market-driven decline.”

The company halted production guidance for fiscal 2026 through 2030 pending a revised business plan expected by the end of September. To support the restructuring, Petra secured lender consent to ensure the Finsch business rescue process does not trigger defaults under its senior bank facilities or second-lien notes. 

The company also warned it could breach minimum liquidity requirements later this year, prompting discussions with creditors and a formal bondholder consent process.

Co-CEO exits

The overhaul will bring leadership changes as well. Joint CEO Operations Juan Kemp will leave the company this month following a mutual separation agreement with the board. Gadodia becomes sole chief executive and joins the board as Petra focuses on preserving liquidity and reshaping the business around Cullinan’s higher-value production.

The restructuring highlights mounting pressure across the diamond sector as slowing Chinese luxury demand and the growing popularity of lab-grown stones weigh on prices. Producers have responded by curtailing operations, reducing inventories and reassessing expansion plans. 

Petra’s decision to place Finsch into business rescue underscores concerns that lower-value diamonds may face a prolonged decline in demand and pricing.
