Newfield Executive Director, Karl Smithson, said the ASX-listed company is ready to commence the drilling and blasting of the underground decline.
Russian diamond mining giant Alrosa has decided to further develop the Aikhal underground mine to 300 meters in depth, making it possible to replenish the raw material base and extend the mine life up to 2044. Implementation of the project to strip and mine the Aikhal pipe reserves at the levels of -100 meters/-400 meters will replenish the miner's reserves by almost 20 million carats and maintain the annual production level of 500,000 tons of ore up to 2044.
Russia's Alrosa has been exploring its options for the currently suspended Mir underground mine development, and has announced that it has worked out a decision-making concept regarding whether to restore Mir as an operating mine or move toward full closure of the mine. Should the miner decide the plan to reopen the Mir mine is economically viable and can be done safely, the earliest it might reopen would be 2030, and it could take even longer.
Lucara Diamond Corp. has announced a 54% increase in the indicated resources of the South Lobe of its Karowe Mine in Botswana, as it undertakes its feasibility study for a potential underground operation. The significant increaase in the availability of diamonds, as well the increased contribution of the higher grade, higher value EM/PK(S) geological ore unit, where some of Karowe's most valuable diamonds, including the 1,109 carat Lesedi La Rona and the 813 carat Constellation were found, signfies a significant boost to the future of the mine.
Stellar Diamonds and parent company Newfield Resources are on the verge of commencing development of their Tongo Diamond Project in Sierra Leone.

Canadian diamond miner Stornoway sold 184,620 carats in two tender sales for gross proceeds of $24.7 million at an average price of US$103 per carat (C$134 per carat) as price weakness returned to smaller and lower quality diamonds, a decline of 7% compared to the second quarter.

Last week, Candian diamond miner Stornoway Diamond Corporation achieved sustained underground mine production at the Renard Diamond Mine following its ramp-up to or above the mine’s design capacity, marking the completion of the underground mine. Matt Manson, President and CEO, commented: “Completion of the underground mine ramp-up at Renard has not been without its challenges.
Canadian miner Stornoway Diamonds reported a net loss of US$27.5 million (C$35.9 million) during the second quarter despite higher revenues, as the transition to underground mining at the Renard mine impacted the company's carat recoveries and sales during the first half of the year. The move underground has taken longer than anticipated, as equipment availability and management problems have slowed their progress. The recorded loss compares unfavorably to the $3.1 million in profit the company achieved in the second quarter last year.
Canadian miner Stornoway Diamonds saw its sales and diamond output slip in the second quarter, with the results, "reflect[ing] the ongoing transition from open pit to underground mining and the introduction of ore-waste sorting." Stornoway held two tenders in Antwerp compared to three in Q1, earning US$21.9 million (C$28.6 million) from the sale of 201,283 carats, compared to US$43.3 million (C$56.6 million) from the sale of 399,135 carats in Q1.
Rain clouds have chased away the forest fire hazard at Stornoway Diamonds' Renard Mine in Quebec, and the miner expects to commence remobilization of staff to the mine this morning, July 4. "Over the last 48 hours, rainfall and a shifting of the prevailing winds have allowed the principal fires south of the Clarence and Abel Swallow Airport to be contained, allowing for the safe transit of mine staff to the Renard Mine. Stornoway expects to recommence full mine operations forthwith." Hopefully this will be the last appearance of the 'dog days of summer' for the Canadian miner.*

Production levels in 2017 had to be scaled back as a result of extracting less ore than planned from its Karowe deposit, forcing the company to focus on mining waste material to ensure future access to larger volumes of ore from the lower-grade but higher-value south lobe.

The project, known as "Cut 9", has been under discussion for five years as part of the Jwaneng Resource Extension Project. This Project led to the development of Cut 8, the $3 billion expansion project designed to prolong the Jwaneng Mine an additional 7 years, ensuring continuous production until at least 2024 and producing 100 million carats.
Last year Rio Tinto’s diamond revenue slid 12%, leading them to review their plans to extend the life of the Argyle diamond mine, considering the global demand for rough had otherwise strengthened, writes The West Australian. Rio Tinto spent $US2.5 billion expanding the Argyle mine below ground with an expected lifespan reaching 2021. Should they decide not to continue with the planned underground extension, the mine’s closure could come considerably sooner. They are yet to announce whether they will continue with the second stage of the underground block cave at the East Kimberley mine.
