JSC National Atomic Company "Kazatomprom" ("Kazatomprom" or "the Company") announces the following update related to the impact of the COVID-19 pandemic on the Company’s business and operations.

“Kazatomprom’s main priority is the health and wellbeing of our staff and their families, our partners, and the communities where we operate,” said Galymzhan Pirmatov, chief executive officer of Kazatomprom. “In April, we announced measures to protect our people by reducing the number of employees on sites to minimum possible levels, for a period of three months. Throughout that time, we have followed government restrictions and health advice, however, we believe that the pandemic-related risks still remain too high for a full return of production employees to our sites. We are therefore extending the period of reduced operational activity for an additional month, with the intention of gradually increasing mine site staff levels at the beginning of August, if it is deemed safe to do so.”

Business continuity plans were implemented at all of the Company’s offices, including the corporate headquarters in Nur-Sultan, Kazakhstan, with nearly all staff working from home. Production employees who remained at the Company’s mines have been working safely with social distancing and strict hygiene protocols in place. Today’s extension of the protection measures for an additional month is not expected to have a material impact on the Company’s 2020 production volume guidance (19,000 tU to 19,500 tU on a 100% basis - attributable production between 10,500 tU and 10,800 tU). Kazatomprom's production decisions and contractual obligations are backed by inventory, and the Company will continue to responsibly manage its supply sources, including purchases in the spot market if necessary, in order to meet its sales commitments (unchanged at 13,500 tU to 14,500 tU).

Kazatomprom’s management team has established a suite of safe operating criteria, which the Company will continue to assess in the coming weeks, prior to implementing any decision to begin a return to normal operating levels. If it is safe to do so, the Company expects to ramp up activity at a staged and gradual pace, beginning with drilling programs at advanced exploration properties, where the implementation of appropriate social distancing and safety protocols is more straightforward. The return of mining subsidiary production employees for the resumption of mine development activities is then expected to proceed in the first week of August.

The Company will continue to monitor the situation at the operations, as well as all regional COVID-19 developments and governmental directives, to ensure that any required actions to reduce the spread and/or impact of the pandemic are implemented without delay. Further information will be included in Kazatomprom’s 2Q20 Operations and Trading Update, to be released on 03 August 2020.
