Cameco COVID-19 Relief Fund Supports 67 Community Projects

Saskatoon, Saskatchewan, Canada, April 30, 2020 ......

Cameco (TSX: CCO; NYSE: CCJ) is pleased to announce that the company is supporting 67 community projects in Saskatoon and northern Saskatchewan through its $1 million Cameco COVID-19 Relief Fund.

“There are so many communities and charitable groups hit hard by this pandemic, yet their services are needed now more than ever,” said Cameco president and CEO Tim Gitzel. “We are extremely happy to be able to help 67 of these organizations continue to do the vital work they do every day to keep people safe and supported through this unprecedented time.”

Approved projects come from 40 Saskatchewan communities from Saskatoon to the province’s far north. A full listing can be found at the end of this release. Included in the support Cameco is providing are significant numbers of personal protective equipment (PPE) for northern Saskatchewan communities and – 10,000 masks, 7,000 pairs of gloves and 7,000 litres of hand sanitizer.

Donations of supplies and money from nearly 100 Cameco employees augmented the company’s initial $1 million contribution. Cameco will move quickly to begin delivering this support to the successful applicants.

“I’m proud of Cameco’s employees for stepping up yet again to support the communities where they live,” Gitzel said. “It happens every time we put out a call for help, a call for volunteers, a call to assist with any of our giving campaigns, and I can’t say enough about their generosity.”

Announced on April 15, the Cameco COVID-19 Relief Fund was open to applications from charities, not-for-profit organizations, town offices and First Nation band offices in Saskatoon and northern Saskatchewan that have been impacted by the pandemic. Eligible applicants could seek grants of up to $50,000 to assist in their efforts to overcome the effects COVID-19 has had on their ability to serve their communities and support people in need.

The initiative also demonstrated the overwhelming need that exists in Saskatoon and northern Saskatchewan in the midst of this pandemic. By the submission deadline of April 28, 581 applications had been received seeking more than $17.5 million in total funding assistance.

“The tremendous need out there is clear,” Gitzel said. “I would just encourage everyone – if you have the ability to help out, to volunteer, to make a donation, please do what you can to assist these organizations with the important work they are doing in our communities.”
