Rio Tinto Exploration Completes 5,340-Metre Drill Program on Three Target Areas at Henday Property

Forum Uranium Corp. ("Forum") announces that Rio Tinto Exploration ("RTX") has completed a 15 hole, 5,340 metre drill program on three target areas at its 40% owned Henday Property, located northeast of Rio Tinto's Roughrider uranium deposit nearby the AREVA/Denison McClean Lake mill in Saskatchewan's Athabasca Basin. Six holes were drilled in the Hollow Lake target area, 6 holes in the Elephant target area, and 3 holes in the Epitaph target area. Whole rock assay highlights from the winter drill program are listed in Tables 1, 2 and 3 from these three target areas. A plan map with drill-hole locations is shown as Figure 1 below.

Hollow Lake: five out of six holes intersected significant alteration. One hole, 16HDY007 intersected anomalous uranium mineralization in two discrete 0.3m uranium-bearing fractures at 177.4m and 182.4m, respectively (Figure 2). Assay results indicate the fracture at 177.4m contains 523 parts per million (ppm) uranium total digestion (UTD), whereas the fracture at 182.4m contains 469ppm UTD. Both intervals are hosted in pelitic gneiss within a 20m interval of pervasive argillization, strong illite, weak hematite, and moderate to strong black chlorite alteration as well as 2.2m of elevated uranium (187-275ppm UTD, Table 2). Four holes drilled within a 200m zone of 16HDY007 have rotated bedding, quartz dissolution, and local silicification of Athabasca sandstone along with moderate to strong argillization, moderate hematite alteration and moderate to strong black chlorite alteration. These factors make the Hollow Lake area a priority target for follow-up work.

Ken Wheatley, Forum's VP of Exploration commented, "The size and strength of the alteration intersected at the Hollow Lake target suggest that uranium bearing fluids have migrated through significant structures in the area. Further work is required to determine the control of uranium mineralization and the potential areas for where it may have been deposited. We are very pleased with the positive results and quality of work from this first pass drill campaign by our partner on this project."

Table 1: Highlights from the Hollow Lake target winter 2016 sandstone and basement assays. All results are reported in ppm. All elements except Boron (B) reported as partial digestion; boron reported as near total digestion.

Epitaph: all three holes contained significant faulting, illitic clay, quartz dissolution, minor red hematite alteration, and rotated bedding in the sandstone, coupled with pervasive clay with weak hematite, limonite, and black chlorite alteration in the basement. A 1.0m interval at 286.8m in hole 16HDY002 returned 214ppm UTD in graphitic pelitic gneiss. Follow-up hole 16HDY004 intersected 131ppm UTD at 256.9m in pelitic gneiss. Structural disruption and alteration of this type is favourable for uranium mineralization, and follow-up drilling is recommended.

Elephant: four out of the six holes drilled contained structurally disrupted sandstone with illitic clay, local minor red hematite alteration, and quartz dissolution. Basement alteration consisted of pervasive, red hematized clay near the unconformity along with black chlorite alteration in shear zones below. Further drilling to follow up areas with uranium-associated alteration and structural disruption is also recommended.

A final report from RTX including a geochemical, radiometric, and geological interpretation of the drill results and recommendations for follow-up exploration is expected in Q2 2016. Samples include both chip samples (3.8-6.0m intervals) and split core (0.3-1.0m intervals) that are taken systematically and submitted to SRC Geoanalytical Laboratories (an SSC ISO/IEC 17025: 2005 Accredited Facility) of Saskatoon, Saskatchewan for analysis. All samples are analyzed using ICP-MS for trace elements reported as partial and/or total digestion, ICP-OES for major and minor elements reported as total digestion, and fusion solution of boron by ICP-OES reported as total digestion.
