  • Petra Diamonds Limited announced on Thursday that it has reached agreement with the National Union of Mineworkers (NUM) with regards to salaries at the Finsch and Koffiefontein operations in South Africa and employees will report for their normal duties on 29 September 2017. A day later, Petra announced the Kimberley Ekapa Mining JV operation has signed the same three year wage agreement as that already signed by the company's other South African operations. The mine will now revert to normal operations following conclusion of the labour disruption.

  • London-listed Petra Diamonds said on Wednesday it had received authorization from the Tanzanian government to resume diamond exports and sales from the Williamson mine. Shares in Petra Diamonds climbed more than 12% from two-year lows following the annoucement. The company said the timing and process for the next diamond export to the company’s office in Antwerp and the sale would be finalized between the company and the government. Petra said no resolution had been reached over the 71,654.45 carat shipment from the Williamson mine that was blocked for export this month.

  • As the company had already warned, Petra Diamonds is currently facing strikes from workers at two of its mines in South Africa prior to the finalisation of its new wage agreement for its operations in South Africa, the company announced in a press release. Petra confirms that since last night it is, "experiencing labor disruption at its Finsch mine and there is also disruption underway at its Kimberley Ekapa Mining JV operations." Reuters adds that members of South Africa’s National Union of Mineworkers (NUM) are on strike over pay, regional secretary Cornelius Manhe said, after mo

  • Petra Diamonds Ltd., the London-based diamond miner with mining operations in South Africa and Tanzania, reported its FY 2017 revenue up 11% to $477.0 million (FY 2016: $430.9 million), though its adjusted earnings before interest, tax, depreciation and amortisation (EBITDA) fell to $157.2 million from $164.3 million in the year before due to delayed ramp-up of the expansion programs and higher cash costs. The miner's net profit after was down 69% to $20.7 million (FY 2016: $66.8 million).

  • Government authorities in Tanzania have seized a shipment of diamonds belonging to London-based Petra Diamonds, saying the miner under-declared the value of its mineral exports. On August 31, customs seized a parcel containing 71,654 carats rough gems at the Dar Es Salam airport as they were being exported to Antwerp by Williamson Diamonds, in which Petra holds a 75% stake and the Tanzanian State 25%.

  • As anticipated, while Petra Diamonds achieved record levels of production and sales in FY 2017, with production up 8% to 4.0 Mcts (FY 2016: 3.7 Mcts) and revenue up 11% to US$477.0 million (FY 2016: US$430.9 million), investors remain worried as the company missed its production and revenue guidance by 8-9% due to the slower than anticipated build-up of its expansion programs across its operations. Furthermore, the company pushed back its production guidance and unveiled higher than expected spending and debt, causing its share price to tumble.

  • As Petra Diamonds approaches the close of financial year 2017 (ending 30 June 2017), it has released a market update revising its production and revenue guidance down by 8-9%, despite the fact that the miner is on track to achieve record revenue and production figures in FY 2017. "However, due to the slower than anticipated build-up of its expansion programmes across its operations, production is now estimated to be ca. 8-9% lower than guidance of ca. 4.4 million carats. As a result, revenue is expected to be ca.

  • The South African government has raised the minimum threshold for black ownership of mining companies to 30 percent in a surprise move that weakened the rand and knocked shares in the London-quoted mining groups Anglo American and Petra Diamonds. Shares in Anglo American have fallen sharply after South Africa announced changes to its mining regulations. They dropped 57p, or more than 5 percent to £10 after South Africa’s mineral resources minister Mosebenzi Zwane said miners have to raise their black-owned stakes to 30% from 26% under a revised version of its mining charter.

  • Petra Diamonds reports its rough diamond output in Q3 2017 (January 1 - March 31 2017) remained steady at 999,768 carats, from 995,905 carats a year earlier; however, the company arrived there by increasing Run of Mine (ROM) production 18% to 760,916 carats while tailings production fell 32% to 238,852, in part due to a planned reduction at Finsch and in part due to heavy rain restricting surface recovery.

  • Petra Diamonds, the London-listed mining group focused on Southern Africa that operates four mines in South Africa and one in Tanzania, has reported that Q1 2017 (1 July to 21 October 2016, covering production and sales from 1 July 2016 to 30 September 2016) production is up 30% to 1,097,523 carats (Q1 FY 2016: 842,796 carats), due to increased contribution from undiluted run-of-mine (ROM) ore, improving ROM grades and additional tailings production from Kimberley Ekapa Mining.

  • Petra Diamonds has released its annual report for FY 2016, with 16% higher rough diamond production at 3.7 million carats leading to only a 1% gain in total revenue at $430.9 million, and a 1% increase in adjusted net profit at $63.6 million. Chairman Adonis Pouroulis states, "While we achieved 16% higher production during the year, revenue was only up 1% as the higher volumes (albeit of lower value goods from the Kimberley tailings operations) were offset by rough diamond prices on a like-for-like basis, being down circa 6% in comparison to FY 2015 ...

  • Johan Dippenaar, the CEO of South Africa-based Petra Diamonds, gives an overview of the history and operations of the mining firm as it heads towards completing a seven-year, $1 billion expansion program that will triple its production. Dippenaar, in London to meet investors after presenting Petra’s 2016 financial results to investment firms, explained to the Daily Telegraph that Petra’s business model is based on acquiring old mines from De Beers and extending their life. “These mines – Cullinan, Finsch, Kimberley – that’s what started De Beers,” he says.

  • "An invasion of more than one thousand illegal diamond miners – zama-zamas – in South Africa’s Northern Cape town of Kimberley is threatening the viability of London-listed Petra Diamonds (Petra) operations and, if left unchecked, could also have serious negative consequences for South Africa’s overall diamond mining and beneficiation industries", writes Miningmx.

  • Paul Zimnisky, author of the Zimnisksy Global Rough Diamond Price Index, writes that the 2016 first half diamond production trends of De Beers and Alrosa - good for 40.7% and 34.7% of global market share value respectively - show diamond production declining as sales climbed significantly compared to H1 2015. These results are consistent with the strategies announced at the start of the year, and were certainly buoyed by a more favorable than expected global economy, the U.S.

  • Petra Diamonds, with interests in five South African and one Tanzanian mine, has reported that production for FY 2016 was up 16% to 3.7 Mcts (FY 2015: 3.2 Mcts), above Company guidance of 3.6 – 3.65 Mcts. FY 2016 revenue was up 1% to $430.9 million (FY 2015: $425.0 million), mainly due to an increase in volumes sold, most notably tailings carats sold from the newly established Kimberley Ekapa Mining operation (KEM).

  • Petra Diamonds Limited said the stone is a Type II diamond of exceptional color and clarity, and is an outstanding example of the large, high quality diamonds for which the mine is known. The diamond will be sold in the last tender of Petra's 2016 financial year which is currently underway in Johannesburg.

  • "The illustrious story of the impeccable blue diamond began in the 17th  century when Jean Baptiste Tavernier, a French diamond merchant, traveller and pioneer of diamond trade with India, first set eyes on a unique and unforgettable diamond in India. The “superfine deep blue” that so captivated Tavernier was later sold to King Louis XIV in 1669 as the famous French Blue, used to adorn the crown of Queen Marie Antoinette.

  • "A century of first-hand experience in the art of managing markets is helping diamond producers accomplish what the rest of the mining industry has been unable to during the commodity collapse: shut down supply," writes Thomas Biesheuvel for Bloomberg Business. With rough diamond prices dropping 18 percent last year, world supply was reduced by a quarter as the biggest producers, De Beers and Alrosa, cut output and sales. That compares with the situation in commodities such as iron ore and copper, "where companies like Rio Tinto Group and BHP Billiton Ltd.
