Total packaged production from Cigar Lake was 3.8 million pounds (2.1 million pounds our share) compared to 3.7 million pounds (1.9 million pounds our share) in the first quarter of 2022. Our share of production was higher in the first quarter of 2023 compared to the same period in 2022 primarily due to an increase in our ownership interest from 50.025% to 54.547%, which took effect on May 19, 2022.

In 2023 and 2024, we expect to produce 18.0 million pounds (approximately 9.8 million pounds our share) at Cigar Lake.
