The acquisition is part of the company’s strategy to stake areas with potential for hosting high-grade uranium deposits.
The company currently manages seventeen projects, comprising 117 claims covering 232,088 hectares.
The acquired properties include Midas, Hearty Bay, Flowerdew Lake, Hobo Lake, Costigan Lake, River Lake and Karpinka Lake.
These claims are located in Saskatachewan, and expand the existing properties of Thompson Lake, Beaver River, Cree Bay and Grey Island.
Fission president, COO and chief geologist Ross McElroy said: "While our primary focus remains exploring our PLN and Clearwater West projects, these new additions are a key component of our project generator business model which focuses on acquiring properties with the potential for near-surface uranium mineralization in the world’s premiere uranium district."
The company has also expanded its Beaver River, Cree Bay, Grey Island and Thompson Lake properties.
