HARFANG ACQUIRES A CU-NI-PT-PD MINERAL PROPERTY AT LAKE

AULNEAU, NUNAVIK (QUÉBEC)

Montréal, May 23, 2018. Harfang Exploration Inc. (“Harfang” or the “Company”) (TSX-V: HAR)

is pleased to announce the acquisition of 132 mining claims (Lake Aulneau Property) located in

the Labrador Through (Nunavik, Québec). The property encompasses 6 copper (Cu), nickel (Ni),

platinum (Pt) and palladium (Pd) prospects and showings, namely Marymac I, Lepage, Island,

Redcliff, Float, and Nine South. The entire property staked by map designation covers 6,202

hectares and is 100%-owned by Harfang. The property is located 125 km south of Kuujjuaq and

265 km north of Schefferville . Mainly focused on gold exploration in Eeyou Istchee James Bay,

Harfang acquired the property as part of its diversification program both in terms of geographical

regions and commodities.

Historical resources were published in previous exploration reports for 4 of the previously-

mentioned mineralized occurrences. They include 1,088,000 Mt @ 2.02% Cu, 0.45% Ni, 1.0 g/t

Pt and 3.1 g/t Pd for the Lepage and Island zones combined, 1,068,000 Mt @ 2.09% Cu and

0.51% Ni for the Redcliff prospect, and 133,000 M t @ 2.10% Cu and 0.43% Ni for the Float

prospect (Figure 1 attached). These estimates are treated as historic information and have not

been verified by the Company. These are considered historical Mineral Resourc es and do not

refer to any category of sections 1.2 and 1.3 of the NI -43-101 Instrument such as Mineral

Resources or Mineral Reserves as stated in the 2014 CIM Definition Standards on Mineral

Resources and Mineral Reserves. The explanation lies in the inability by the Company to verify

the data acquired by the various historical drilling campaigns and other sampling works. The

qualified person has not done sufficient work yet to classify the historical estimates as current

Mineral Resources or Mineral Reserves. The Company is not treating these historical estimates

as current mineral resources. These resources were calculated from diamond drillholes

completed in the 1970’s and 1980’s. Anomalous gold and silver values are locally associated to

Ni-Cu-Pt-Pd occurrences.

The Labrador Through is known to host significant Cu- Ni-Pt-Pd lenses associated to mafic and

ultramafic sills emplaced in the Murdoch Formation. Most of the m ineralization on the Lake

Aulneau Property, which shares similarities to the geological setting at the Raglan Mine (Nunavik),

is hosted in these sills. Minor mineralization also extends into adjacent volcanic and sedimentary

rocks. The last drilling campaign was done in 1988. Since then, exploration activity in the area

was limited to the resampling of a few narrow intervals in drillcores, brief prospecting phases and

2 airborne magnetic and electromagnetic surveys completed in 2003 and 2011. Both geophysical

surveys outlined the conducti ve nature of known sulfide zones including the delineation of on-

strike areas of conductance. However, based on published statutory reports, few work was

accomplished on electromagnetic conductors outlined in 2003 and no follow up was done on

anomalies detected in 2011.

Harfang will proceed to a geological compilation to enhance the full potential of this sector and

generate exploration targets.
