Showing CAPEX to be lower than in the 2019 Prefeasibility report, particularly with the pressures of high global inflation, is a remarkable achievement and speaks volumes regarding the team's design and planning abilities. Ross McElroy, President and CEO of Fission, commented, " With greatly enhanced economics, including an increase of 42% to the mine life, an incredible 71.5% increase in post-tax NPV and a 10.2% growth in post-tax IRR, this feasibility study confirms the Tier 1 PLS project as one of the most economically significant and elite uranium development projects in the world. The FS has an effective date of January 17, 2023. With nuclear energy and the uranium sector strengthening year on year, Fission is ideally positioned to continue developing PLS through the environmental assessment and licensing phase. The results confirm the economic strength of the PLS project as well as its minimal environmental footprint. Of additional note, initial CAPEX is marginally lower (~2%) than the PFS for a total of $1.155B – a remarkable achievement given current global inflation. The exchange rate used is 0.75 US$/ C$1.00.

All currency figures are expressed in Canadian dollars unless denoted otherwise. Highlights include a longer mine life of 10 years, greatly increased after-tax NPV of $1.204B at 8% discount, higher after-tax IRR of 27.2% while still maintaining a very low OPEX of $13.02/lb.
