The Triple R deposit comprises the R00E zone and the R780E zone with an overall strike length of approximately 1.2km.
The deposit is estimated to contain inferred mineral resource of 25.9 million lbs U3O8 and high-grade zone of 13.9 million lbs U3O8.
The company plans to conduct winter and summer drilling programs on the deposit this year.
Fission said that around 75% of the mineral resource has been classified as an indicated resource, which represents the continuity of the mineralization.
Fission president, COO and chief geologist Ross McElroy said: "The entire deposit is located in basement rock, which is a preferred host rock for development of economic uranium deposits in the Athabasca Basin region.
"All in all, these phenomenal results represent an incredible milestone for the team, the company and our shareholders."
