Confirmed COVID-19 Case Count for KATCO JV

JSC National Atomic Company “Kazatomprom” (“Kazatomprom” or “the Company”) and its France-based  joint venture partner, Orano Mining, announce the following update related to the COVID-19 outbreak at Joint Venture KATCO LLC (“KATCO”), operating in the Turkestan region of the Republic of Kazakhstan.

As of 22 January 2021, all employees and contractors at KATCO’s Moinkum and Tortkuduk operations were  tested for COVID-19; the final reports have now been received, showing 128 positive cases out of the 666 PCR tests performed.

Personnel who tested positive were isolated and are receiving treatment if required, and contact tracing was completed to quarantine exposed individuals. In accordance with the orders of the Chief State Sanitary Doctor of the Suzak District of the Turkestan Region, both sites were placed under a quarantine, which will remain in effect until retesting confirms that it is safe to lift the restrictions.

Due to the high case count and the introduction of the quarantine, several non-core site activities have been suspended. However, KATCO is able to safely continue key operations and expects that the current situation will not have a significant impact on its planned 2021 annual production volumes.

Kazatomprom and Orano are providing ongoing support to affected employees and ensuring strict compliance with the requirements of authorized government agencies to prevent the spread of COVID-19.
