2.58km trend (that are not yet included in the Triple R deposit)

— 16 holes focused on key regional exploration targets

— 32 line-km Moving Loop Electromagnetic (“MLTDEM”) survey targeting

Paterson Lake Corridor to identify further drill targets

— 138 line-km 2D Marine Seismic Survey aimed at identifying areas of

stronger, wider mineralization and generating data necessary for

geotechnical engineering

— Pre-Feasibility activity, including geotechnical borehole testing,

hydrogeology monitoring wells and metallurgical studies

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

“This exciting summer program follows the tremendous success of our winter drilling, which opened up new areas of shallow, high-grade mineralization and delivered the largest mineralized trend in the Athabasca Basin region – a trend that is still wide open. This new program will focus on aggressive growth of our high-grade zones to the east and west of the 2.58km trend, together with a large number of key regional targets. We will also be testing between our mineralized zones to evaluate the potential of connecting them.”

— Growing and connecting the zones with 36 holes targeting the R840W,

R780E and R1620E high-grade, shallow mineralized zones along the 2.58km

mineralized trend, which remains open in multiple directions. A

particular focus will be the new, high-grade R840W and R1620E zones

discovered during the 2016 winter program and also testing the

prospective 480m gap between the R600W and R00E zones, where PLS16-472

intersected mineralization on line 435W.

— Large Regional Focus with sixteen regional exploration holes in 10 core

holes and 6 Reverse Circulation (“RC”) holes, will test a series of

high-priority exploration targets on multiple basement Electromagnetic

(“EM”) conductors within the Patterson Lake Conductive Corridor (“PLCC”)

to the north, east and west of the 2.58km long PLG-3B mineralized trend,

as well as EM conductors within the Forest Lake Conductive Corridor

(“FLCC”).

— Ground Geophysics to help locate and prioritize new drill targets,

featuring a 32 line-km Moving Loop Electromagnetic (“MLTDEM”) survey

will be completed on the Patterson Lake Corridor, focusing primarily on

the group of basement EM conductors north and west of the 2.58km

mineralized trend.

— 2D Marine Seismic Survey: A 138 line-km 2D Marine Seismic survey will

provide coverage of the Patterson Lake. The survey will image the

unconformity (bedrock / overburden interface) and will provide important

data for the Geotechnical Engineering component. In addition, this

survey may help to image the major cross-faults suspected to exist along

the mineralized trend. Cross-faults can be important in structurally

hosted deposits in cases where they create dilatency within the

structural fabric where the result may be wider and stronger

mineralization. The marine seismic survey may prove to be the first

geophysics survey on PLS to properly resolve these difficult to detect

cross-faults.

— Activities toward PFS Study: A number of activities, including

geotechnical drilling, metallurgical testing and environmental data

collection, will be undertaken to support work towards a PFS. The

geotechnical work will be conducted under the design and supervision of

BGC Engineering Inc., who were the lead 3rd party consultants for the

geotechnical component of the 2015 PEA study. Metallurgical work will be

conducted under the supervision of Melis Engineering Ltd. widely

recognized as one of the premiere experts in this area. Canada North

(CanNorth) Environmental Services designs and manages all aspects of

baseline environmental programs for PLS. This summer, CanNorth will

complete the hydrology, summer aquatic, and meteorological assessments

to lengthen the hydrological and meteorological classification of the

area and to provide information for further baseline programs.

— Ring Dike Geotechnical Soil Borehole Testing: Four overburden

boreholes will be drilled along the expected R00E perimeter wall

area. This testing will aid in understanding of the overburden

material properties and characteristics for future open-pit mine

design. This survey involves specialized drilling and will include

Triple Tube coring, packer testing of bedrock and piezometer

installation.

— Regional Hydrogeology Monitoring Wells: Eight regional hydrogeology

monitoring wells will be drilled using RC drills already on-site.

These holes are designed to provide long-term water flow analysis in

areas that are contemplated for major infrastructure such as:

overburden dump, proposed plant site, lake-shore south-west of

proposed open-pit, and north-west and south-west corners of the

proposed development areas.

— Phase 2 Metallurgical Study: The 1st Phase of metallurgical analysis

that was completed for the 2015 PEA study, centered on the Triple R

deposit ore mineralogy and tested grindability and leachability.

Phase 2, to be conducted this summer, will focus on proving the

performance and efficiency of the processing steps post leach, which

involves: solid/liquid separation test work to size the CCD circuit,

solvent extraction test work, impurity removal test work, yellowcake

precipitation test work and effluent / tailings treatment. Sample

material for Phase 2 work will come from 3 HQ diameter drill holes

strategically located in the R780E zone.

PLS Mineralized Trend & Triple R Deposit Summary

Uranium mineralization at PLS occurs within the Patterson Lake Conductive Corridor and has been traced by core drilling approximately 2.58km of east-west strike length in five separated mineralized “zones”. From west to east, these zones are: R840W, R600W, R00E, R780E and R1620E. Thus far only the R00E and R780E have been included in the Triple R deposit resource estimate.

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 combined strike length validated by a resource estimate of approximately 1.05km with the R00E measuring approximately 105m in strike length and the R780E zones measuring approximately 945m in strike length. A 225m 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 zone is 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 to 60m 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 from the R600W zone and the newly discovered R840W zone, located 480m and 765m respectively to the west along strike have significantly upgraded the prospectivity of these areas for further growth of the PLS resource on land to the west of the Triple R deposit. The recently discovered high-grade mineralization in the R1620E zone, located 300m to the east along strike has significantly upgraded the prospectivity for further growth of the PLS resource to the east of the Triple R deposit.
