ALROSA has commenced development of the Karpinsky-2 kimberlite pipe at the M.V. Lomonosov diamond field in Russia’s Arkhangelsk region. This becomes the third operational pipe at the site, alongside Arkhangelsk and Karpinsky-1.
Karpinsky-2 holds more than 40 million tonnes of diamond-rich ore. Initial pilot mining in 2018 confirmed its viability, leading to the start of full-scale development earlier this year. ALROSA CEO Pavel Marinychev initiated the design phase during a recent visit to Severalmaz, the company’s regional arm.
While there, Marinychev assessed Severalmaz’s performance for 2025. The company surpassed ore extraction goals in the first five months and improved efficiency by reducing maintenance-related downtime. These efforts contributed to a 9.4% rise in ore processing and yielded over 1.2 million carats of rough diamonds.
He also commended progress on a water recycling initiative at the Lomonosov processing facility and emphasized the need to finish building a gym for workers at the shift village by year-end.
“I am confident that the Severalmaz team’s efforts will continue to propel the company forward. We’re dedicated to maintaining safe working conditions and supporting the development of the Arkhangelsk region,” Marinychev stated.
ALROSA remains the world’s top diamond producer, responsible for 30% of global and 90% of Russia’s diamond production. In 2024, the company produced 33 million carats, with reserves exceeding 1 billion carats.
