Australia’s Paladin Energy has received the final green light it needed from Canadian authorities to buy Fission Uranium in a C$1.14 billion ($789.1 million) deal that cements is position as a major global producer, it said on Thursday.

Paladin got the clearance under the Investment Canada Act on Wednesday and said the deal under which it would acquire Fission’s advanced PLS project in Saskatchewan was expected to be completed by early January 2025.

he clearance comes as prices for the nuclear fuel surge on expectations of a demand spike as the energy transition unfolds. Shares fell 1.8% amid weakness in the mining sector.

The Canadian government in October stepped in to review the proposed tie-up on national security grounds, raising concerns it may be derailed by the county that has become increasingly sensitive towards strategic resource firms being taken over by overseas buyers.

Paladin has agreed to several conditions Canada has attached to the merger including not to use any China-sourced finance for funding PLS, or to sell PLS’s uranium directly or indirectly to any China customers beyond China General Nuclear Power Group, which has an existing offtake agreement, it said.

Canada in July cracked down on big mining takeovers, saying it would only approve foreign buyouts of large Canadian firms involved in critical minerals production “in the most exceptional of circumstances.”
