Fission Uranium found the mineralization during drilling of the first three holes of the 20,000m 60-hole summer drill program.
One hole was drilled on the R600W zone, while the other two were drilled on the R780E zone.
The company said all three holes returned strongly radioactive mineralized intervals measuring more than 10,000 cps and drill results at R600W show increased similarities to the shallow, high-grade R780E zone.
Hole PLS15-389, drilled at the R600W zone, returned 8.21m total composite mineralization of over 10,000 cps radioactivity in 76m of total composite mineralization.
Hole PLS15-388, drilled at R780E Zone, returned 56.5m total composite mineralization over a 110.5m section.
Fission Uranium president, COO, and chief geologist Ross McElroy said: "With a strong and shallow new high-grade hole at R600W and more high-grade results at R780E zone, the summer program is off to a great start.
"What has the team particularly excited is not only the discovery of new high-grade mineralization on line R600W but also the increasing geological similarities between the R600W and R780E zones.
"This matters because, while R600W is still at a relatively early stage, R780E has turned out to be a huge, high-grade and shallow zone that contains 96% of the uranium resource at the Triple R deposit."
Fission Uranium has 100% ownership of the PLS property, which features17 claims situated on the southwest margin of the Athabasca Basin.
PLS is host to the Triple R deposit, which is claimed to be the largest undeveloped uranium deposit in Athabasca Basin District.
