Step-Out Drilling Intersects High-Grade Radioactivity at PLN

High-Grade Mineralization Expands Up-Dip and On-Strike

Kelowna, December 12, 2022 - Fission 3.0 Corp. (TSXV: FUU) (OTCQB: FISOF) (Fission 3" or "the Company") is pleased to announce the results of the second and third follow up holes (PLN22-039 and PLN22-040 respectively), as well as an additional fourth follow up hole (PLN22-041) to the new high-grade discovery hole PLN22-035 at the A1 Conductor. Two of the three holes intersected significant radioactivity; PLN22-040 along strike from the discovery hole, and PLN22-041 up-dip from PLN22-038 (see Press Releases Nov 21, 2022, and Nov 30, 2022). This completes the PLN fall drill program on the Company's 100% owned Patterson Lake North "PLN" project in the southwest Athabasca Basin region of Saskatchewan, Canada. Drilling at A1 is scheduled to restart in early January and a large drill program is being planned.

Drilling Highlights from follow up holes PLN22-039, PLN22-040 and PLN22-041:

PLN22-040 was a 23 m step out targeting along strike and grid south from discovery hole PLN22-035 and intersected the radioactive structure over 11.5 m between 260.0 m and 278.0 m.

• 8.5 m total composite mineralization >300 cps (between 260.0 m to 268.5 m), including2.5 m of total composite mineralization >10,000 cps over a 3.0 m interval (between 261.0 m and 264.5 m) with a peak of 63,400 cps at 262.5 m

• 1.0 m >300 cps (between 272.0 to 273.0) and 2.0 m >300 cps (between 276.0 m to 278.0 m)

PLN22-041 intersected the radioactive structure up-dip from PLN22-038 at a vertical depth of 200m.

• 12.0 m continuous mineralization >300 cps (between 198.5 m to 210.5 m), including 1.85 m of total composite mineralization >10,000 cps over a 5.25 m interval (between 204.5 to 209.75 m) with a peak of 18,800 cps at 208.5 m

PLN22-039 was planned to target on section and 15 m down-dip from the discovery hole PLN22-035. Unfortunately, due to significant drill hole deviation the hole steepened excessively, and the target was missed. A structure was intersected 42m down dip from 274.5 m to 283.0 m. No anomalous radioactivity was recorded.

Raymond Ashley, Vice President Exploration, commented:

"We are very pleased that the follow up holes continued to intersect strong radioactivity and the company has begun to expand on the strong results from discovery hole PLN22-035 along strike, and up-dip towards the Athabasca Unconformity. These initial drill holes into this new discovery will provide the framework and basis for designing the upcoming winter 2023 drill program to commence in early January."

Natural gamma radiation in the drill core that is reported in this news release was measure in counts per second (cps) using a handheld Radiation Solutions RS-125 spectrometer. The Company considers greater than 300 cps on the spectrometer as anomalous, >10,000 cps as high grade and greater than 65,535 cps as off-scale. The reader is cautioned that scintillometer readings are not directly or uniformly related to uranium grades of the rock sample measured and should be used only as a preliminary indication for the presence of radioactive materials. All depth measurements reported are down-hole and true thickness are yet to be determined. Samples from the drill core are split in half on site and are standardized at 0.5 m lengths. One half of the split sample will be submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) in Saskatoon, SK. for lithogeochemical analysis using their "Uranium Package".
