Harfang Announces an Important Summer Exploration Program on its Serpent

Property (James Bay, Québec)

MONTREAL, May 12, 2020 -- Harfang Exploration Inc. (“ Harfang”) (TSX-V: HAR) is pleased to provide new information on a

recently completed Induced Polarization (“IP”) geophysical survey and an update on upcoming summer exploration activities to

be conducted on its 100% owned Serpent Property (“Property”) in James Bay (Québec) (Fig. 1).

The IP survey completed over the Mista trend successfully detected a more than 800 m long chargeability axis superposed to

the Mista Cu-Au-Ag prospect (0.99% Cu, 0.20 g/t Au and 7.7 g/t Ag over 11.7 m in trenching). That prospect refers to a sulfide

-bearing quartz-rich arenite injected by quartz veins already traced at surface over 350 m in length by Harfang’s team. The IP

axis suggests the continuation of the mineralization underneath soil and vegetation toward the west ( Fig. 2). The result of the

survey confirms the relevance of Harfang’s method to identify mineralized rocks by mapping conductivity (resistivity) and

chargeability of metallic minerals in the bedrock.

This summer, we will extend the IP survey over the gold-in-till anomaly covering a 4 km 2 area in the southwestern part of the

Property. That anomaly was defined by a cluster of 9 till samples containing between 26 and 324 gold grains ( see press

release dated January 16, 2020) (Fig. 3). Gold analytical results of the non-magnetic heavy mineral concentrates of these tills,

recently obtained from Actlabs (Ancaster, Ontario), returned very significant values including many samples grading from 1 to

>30 g/t Au ( Fig. 4). According to Stuart Averill (P.Geo), founder and chairman of Overburden Drilling Management Ltd.

(“ODM”), the gold-in-till anomaly at Serpent may be considered as one of the most significant in Canada. ODM was mandated

to proceed with the gold grain count of the till samples. Harfang considers that this unexplored portion of the Property

represents a high-priority prospective target and warrants a serious exploration effort. High-grade gold occurrences at Serpent

are mainly associated with shear zone-hosted quartz veins. The major East-West structural break extending over more than

4 km, which is interpreted from magnetic discontinuities, represents a prime target up-ice of the gold-in-till anomaly ( Figs. 3

and 4).

Summer activities will include extensive prospecting, soil/till sampling and mechanical trenching over the gold-in-till anomaly

and the structural break. A drilling program could be designed following detection of IP anomalies and associated gold

mineralization.

Harfang’s employees and its contractors will operate under a COVID-19 management and mitigation plan. The Corporation will

ensure the health and safety of all individuals involved on the project. To date, our workforce remains healthy and free of

symptoms of the virus.

The technical and scientific information in this press release has been prepared and approved by François Huot, P.Geo, Chief

geologist at Harfang, a "qualified person" as defined by NI 43-101.

Serpent Property

The Serpent Property, adjacent to the James Bay Road, is located about 80 km south of Radisson. The Property is composed

of 552 mining claims covering an area of 28,312 hectares. It is adjacent to the La Pointe gold deposit and the recently

discovered La Pointe Extension owned by Quebec Precious Metals Corporation and is located near the contact between the

La Grande and Opinaca subprovinces.

Quality control

Till samples were collected from hand-dug pits at depths up to 1 m by employees from SL Exploration Inc. Sampling sites are

separated from each other by approximately 200-250 m and distributed along lines spaced 1 km apart. Each sample (11-17

kg) was placed in a plastic bag which was identified by a specific tag number and securely sealed with fibertape. Samples

were sent in two separate batches to ODM (Nepean, Ontario) where they were processed. The non-magnetic heavy mineral

concentrates of each sample were then sent to Actlabs (Ancaster, Ontario) to be analyzed for gold by neutron activation.

Till is a transported surficial media produced during active glaciation that may be affected by subsequent surficial processes

resulting in the possible modification of the gold content. As such, the occurrence of a gold anomaly in till is not conclusive

evidence of a mineral deposit existing within the Property limits.

The sampling procedure and the quality control related to the till program followed protocols developed by SL Exploration and

ODM. Interpretation of the results was done by Les Consultants Inlandsis, ODM and Harfang’s qualified employees.
