Fission Announces $6.95M 11,000M Drill Summer Program at Patterson Lake South

Mr. Ross McElroy President, COO, and Chief Geologist of Fission Uranium reports

Fission Uranium Corp. (TSX.V: FCU), the operator, and its 50-per-cent joint venture (JV) partner Alpha Minerals Inc (TSX.V: AMW). have approved a $6.95-million exploration program at PLS in Canada's Athabasca basin. The program will include approximately 11,000m of drilling in 44 holes. In addition ground geophysics surveys will be conducted on two unexplored highly prospective areas on the property. Drilling is expected to start in early July and will focus primarily on the delineation and expansion of the recently discovered high grade discovery zones R00E, 390E, and mineralization of R780E.

The 2013 summer program is an immediate follow-up to the highly successful winter program that discovered high-grade uranium in three separate zones along an 850m trend along strike hit mineralization on 82% of its drill targets (see news release dated April 15, 2013).

Ross McElroy, President, COO, and Chief Geologist for Fission, commented, "The success of the winter program and the results of the recently completed radon survey extension has enabled us to define a very strong set of targets. With three rigs, three barges and the clear goal of expanding our discovery, this is going to be an aggressive program and we're looking forward to getting started."

Fission's team will use a combination of RC drilling for pre-collaring and two diamond drill core rigs to drill bedrock. Barges will be used to test targets on the R390E and R780E zones as well as testing additional targets along trend within Patterson Lake, both to the SW and NE of the currently known mineralized zones. These targets were identified during an extension to the same radon survey that aided with the first discovery holes at the R390E and R780E Zones at PLS and include the strongest radon value in water anomaly to date on the property on line 945E (see news release dated May 6, 2013).

Other additional work during this period will include sampling for the purpose of metallurgical testing and establishing an environmental base line study in order to have independent data recovered over a sufficient time period for future environmental reporting purposes.

Key Technical Information

Summary of Uranium Discovery Zones

The R00E, R390E and R780E zones are all along strike of each other along an approximate 850m trend. Currently the zones are separated by approximately 300m (R00E to R390E) and 360m (R390E to R780E) by a lack of drilling.

The R00E Zone has been defined by mineralization in 29 drill holes over a strike length of approximately 150m between lines 060W and 090E and up to greater than 50m width (line 025W), including an intersection of 4m @ 20.73% U3O8 within 22.0m @ 4.8% U3O8 (PLS13-043) (see news release dated May 16, 2013). Additional assays are pending from holes in this zone.

The R380E Zone has been defined over a strike length of approximately 60m by 11 drill holes, including an intersection of 10.5m @ 29.26% U3O8 within 53.0m @ 6.57% U3O8 (PLS13-051) (see news release dated Apr 22, 2013). Additional assays are pending from holes in this zone.

The R780E has been defined by just 3 holes on one section line (line 780E). Strike length and width of the zone are yet to be determined. Assays from holes in this zone are still pending.

Patterson Lake South Property

Fission is Operator of the 31,039 hectare PLS exploration project, which is a 50%/50% Joint Venture held with Alpha Minerals Inc. PLS is accessible by road with primary access from all weather Highway 955, which runs north to the former Cluff Lake mine, (greater than 60M lbs of U3O8 produced), and passes through the nearby UEX-Areva Shea Creek discoveries located 50km to the north, currently under active exploration and development.
