Petra Diamonds Shares Suspended as Miner Fights for Survival

(IDEX Online) - Petra Diamonds, once one of the world's largest independent diamond producers, had trading in its shares suspended on the London Stock Exchange on November 2 after failing to publish its annual accounts.

Petra is struggling with net debt of $322 million, the loss of a major mine and a prolonged collapse in rough-diamond prices.

Its Finsch operation in South Africa has entered business rescue and production has been suspended, while its only remaining producing mine, Cullinan, could be put up for sale.

The shares suspension followed Petra's failure to meet the October 31 deadline for publishing audited results for the year ended June 30, 2026, a move that will undermine confidence in the company and complicate efforts to attract buyers or secure fresh financing.

In a November 2 announcement, Petra said: "The Group audit remains in progress. The Company continues to work closely with its auditors to complete the audit and publish its annual financial report as soon as practicable.

"It intends to seek restoration of listing and resumption of trading following publication, subject to the agreement of the FCA and the London Stock Exchange respectively. Restoration will not be automatic upon publication, and there can be no certainty as to its timing."

Petra's financial position has deteriorated as the market for smaller rough diamonds has weakened, operating costs have risen and the company has lost a substantial part of its production base.

The crisis is particularly acute in South Africa, where the government has established a task team to help an industry facing falling output, mine closures and job losses.

Finsch, which accounted for about 34% of group revenue in fiscal 2025, entered business rescue in May and suspended production in June.

More than 90% of its output was below two carats, leaving it exposed to a segment of the market where prices have fallen sharply. Creditors have since approved a plan to sell the mine's assets after attempts to find a viable way to restart operations failed.

Petra has already sold two other operations, Koffiefontein in South Africa and Williamson in Tanzania. That leaves Cullinan, famous for producing the 3,106-carat diamond from which the Great Star of Africa in the British Crown Jewels was cut, as its only producing mine.

Cullinan offers some hope. Its larger stones and fancy-color diamonds have proved more resilient than the smaller goods dragging down the market. Petra reported an average price of $106 per carat for its Cullinan production in fiscal 2026, up 11% year on year.

But the mine may now have to be sold to keep the wider business afloat. Petra launched a strategic review in October and appointed South African adviser Questco Corporate Advisory to seek expressions of interest from potential investors and buyers.
