Fission Uranium Corp.: Triple R PEA Shows US$14.02/lb OPEX, 46.7% Pre-Tax IRR and $1.81 Billion Pre-Tax NPV

KELOWNA, BRITISH COLUMBIA--(Marketwired - Sept. 3, 2015) - FISSION URANIUM CORP. ("Fission" or "the Company") (TSX:FCU)(OTCQX:FCUUF)(FRANKFURT:2FU) is pleased to announce the summary results of a National Instrument 43-101 compliant Preliminary Economic Assessment ("PEA") for the high-grade uranium resource identified to date on the Triple R Uranium Deposit, at its 100% owned PLS property in Canada's Athabasca Basin region. The PEA was prepared by RPA Inc. ("RPA").

Highlights

• Base case pre-tax Net Present Value ("NPV") of $1.81 billion, post-tax NPV of $1.02 billion (10% discount rate)
• Mine life of 14 years producing an estimated 100.8 million pounds of yellowcake at a metallurgical recovery of 95% with 77.5 million pounds of U₃O₈ recovered in the first 6 years of production
• Average annual production of 7.2 million lbs U₃O₈ over the life of mine
• Base case pre-tax Net Cash Flow over the proposed mine life of $4.12 billion, post-tax Net Cash Flow of $2.53 billion
• Base case pre-tax Internal Rate of Return ("IRR") of 46.7%, post-tax IRR of 34.2%
• Pay back estimated at 1.4 years (pre-tax), pay back at 1.7 year (post-tax)
• Estimated initial capital costs ("CAPEX") of $1.1 billion
• Average operating costs ("OPEX") of US$14.02/lb U₃O₈ over the life of mine

(Base case using US$65/lb U₃O₈ and an exchange rate of US$0.85:C$1.00). All values in C$ unless otherwise noted.

The PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied that would enable them to be categorized as Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. There is no certainty that the PEA will be realized.

The PEA study considers the PLS project as a stand-alone mine and mill operation, which includes development and extraction of the R00E and R780E zones (Triple R deposit). Due to the early stage of drill definition, the PEA does not include the recently discovered R600W zone.

The study envisions a combination of open-pit and underground mining, with a dyke system (dyke and slurry wall) for water control. High-grade mineralization (above 4% U₃O₈) is captured within the open pit, eliminating the need for expensive, specialized underground mining methods. This hybrid open pit and underground mining results in an OPEX cost of US$14.02/lb U₃O₈ over the life of mine, making Triple R potentially one of the lowest cost uranium producers in the world.

These results may be further enhanced with the addition of the R600W zone discovered 495m along strike to the west of R00E zone. Although not included in the PEA production schedule, definition drilling continues to expand the known mineralization since the discovery of high-grade mineralization within R600W zone during the winter 2015 drill program (see news release March 01, 2015).

Ross McElroy, President, COO, and Chief Geologist for Fission, commented,

"This PEA is an incredibly important milestone, and shows the viability of development and profitability of the unique, shallow, large and high-grade Triple R uranium deposit. The study confirms this unique deposit is a robust project with very strong economics. With anticipated operating costs of US$14.02/lb and a pre-tax IRR of 46.7%, we are looking at low cost production with a payback and highly profitable life of mine. It's also important to note that the recently discovered, high-grade R600W zone, which was not included in the PEA, has the potential to add a great deal to the bottom line as the Triple R continues to grow. Additionally, a mill at PLS has the potential to become a key centerpiece for the Western Athabasca Basin - with the potential to process ore from other high-grade projects in the region as they are taken into production."

PEA METHODOLOGY DETAILS

The PEA was prepared by independent consultants led by RPA Inc., who carried out resource estimation and mining work, assisted by BGC Engineering Inc. (geotechnical aspects), DRA Taggart (process and infrastructure), and Arcadis Canada Inc. (environmental and radiological considerations).

In addition to managing radiological issues common to high-grade uranium mining, a key technical challenge to developing the operation will be water control related to Patterson Lake and saturated sandy overburden. The PEA proposes a system of dykes and slurry walls - proven techniques successfully implemented at a number of Canadian mining operations, including the Diavik diamond mine and the Meadowbank gold mine. The development scenario does not require any new, untested, conceptual mining or construction methods.

PLS Mineralized Trend & Triple R Deposit Summary

Uranium mineralization at PLS has been traced by core drilling approximately 2.31 km of east-west strike length in four separate mineralized "zones". From west to east, these zones are; R600W, R00E, R780E and R1620E.

The discovery hole of what is now referred to as the Triple R uranium deposit was announced on November 05, 2012 with drill hole PLS12-022, from what is considered part of the R00E zone. Through successful exploration programs completed to date, it has evolved into a large, near surface, basement hosted, structurally controlled high-grade uranium deposit.

The Triple R deposit consists of the R00E zone on the western side and the much larger R780E zone further on strike to the east. Within the deposit, the R00E and R780E zones have an overall strike length of approximately 1.2m with the R00E measuring approximately 125m in strike length and the R780E zones measuring approximately 900m in strike length. A 225 m gap separates the R00E zone to the west and the R780E zones to the east, though sporadic narrow, weakly mineralized intervals from drill holes within this gap suggest the potential for further significant mineralization in this area. The R780E zones are located beneath Patterson Lake which is approximately six metres deep in the area of the deposit. The entire Triple R deposit is covered by approximately 50m of overburden.

Mineralization remains open along strike both to the western and eastern extents. Mineralization is both located within and associated with a metasedimentary lithologic corridor, associated with the PL-3B basement Electro-Magnetic (EM) Conductor. Recent very positive drill results returning wide and strongly mineralized intersections approximately 495m west of the Triple R deposit, have significantly upgraded the R600W zone to a very prospective area for further growth of the PLS resource. The R600W zone is covered by approximately 100m of overburden.

Patterson Lake South Property

The 31,039 hectare PLS project is 100% owned and operated by Fission Uranium Corp. PLS is accessible by road with primary access from all-weather Highway 955, which runs north to the former Cluff Lake mine and passes through the nearby UEX-Areva Shea Creek discoveries located 50km to the north, currently under active exploration and development.
