Fission underground-only PFS slashes capex

British Columbia-based Fission Uranium on Monday outlined the potential for “highly economic “ production at the Patterson Lake South (PLS) project in the Athabasca basin of Saskatchewan by focusing on an underground-only mining scenario.

Shifting to an underground-only option, as opposed to the hybrid mine approach of underground and openpit mining outlined in an earlier PFS, Fission has reduced the construction timeline of the mine at the Triple R deposit at PLS by one year and slashed the capital costs by one fifth, while still enjoying a strong return on investment.
