HARFANG ANNOUNCES SUMMER EXPLORATION PLANS AT ITS GOLD

AND CSM PROPERTIES IN EEYOU ISTCHEE JAMES BAY, QUEBEC

MONTREAL, May 30th, 2024 - Harfang Exploration Inc. (TSX.V: HAR) (“Harfang” or the “Company”) is pleased to announce

exploration plans for its portfolio of wholly -owned gold and critical and strategic minerals (“CSM”) assets in Eeyou Istchee

James Bay, Quebec (Figure 1).

“This will mark the first field season for the new Harfang team ,” commented Rick Breger, President and CEO of Harfang .

“We have been very busy compiling all the existing geoscience data in preparation for the Summer 2024 exploration

program. The overarching goal of this summer’s program is to gain focus so we can put together a long-term strategic plan.

I believe a proper evaluation of our entire portfolio is of utmost importance before we can begin any discussion on strategy.

As such, we will be focusing on surface exploration which is a cost-effective way to gain the understanding we need before

we can determine next steps.”

“Last summer was tough,” commented Ludovic Bigot, Harfang’s VP Exploration. “The forest fires had an enormous impact on

the land and the entire Cree Nation. In fact, approximately 11% of the land and 60% of the traplines were affected by the

fires. At Harfang, a significant portion of the assets were completely burned, result ing in unprecedent rock exposures that

present a unique opportunity for geological study. We have recently acquired satellite images and have been using this

data to help prioritize existing areas of interest and explore for new ones. While the 2023 forest fires prevented us from

exploring as initially planned, the significant lithium discoveries made during a very short field season open promising

expectations for the upcoming 2024 program.”

Serpent-Radisson:

The summer 2024 exploration program will follow up on the successful 2023 exploration activities when the Company

discovered spodumene in pegmatite dykes, known as the Améliane showing. The Company reported assay results with

highlights including: 4.56% Li2O, and 0.82% Li2O over 20.0 metres, (incl. 1.46% Li2O over 6.0 metres), in a grab and channel

sample, respectively (see news release dated December 6, 2023).

The Summer 2024 program will focus on additional prospecting around known lithium targets and investigating new lithium

targets identified in the recent joint targeting study (see news release dated April 3, 2024) . In addition, t he main gold

discoveries on the central-western portion of the property will be revisited to gain more geological insights. These include the

Stu Zone (6.06 g/t Au over 7.55 metres) and the Goldhawk Zone (2.69 g/t Au over 11.98 metres) (Figure 2).

The overall goal of the Summer 2024 exploration program at Serpent-Radisson is to advance the geological

understanding for both lithium and gold systems, and to identify potential drill targets.

Lac Menarik:

The summer 2024 exploration program will follow up on the winter 2023 drilling program that confirmed broad gold

intervals in a highly altered and brecciated monzonite that are open at depth in the Pierre and Pierre Ouest zones (Figure

3). The Company reported assay results with highlights including: 1.15 g/t Au over 47.0 metres ( incl. 3.75 g/t Au over 7.0

metres), 1.75 g/t Au over 21.0 metres (incl. 2.49 g/t Au over 14.1 metres ), and 0.54 g/t Au over 75.0 metres (see news

release dated May 11, 2023).

The Summer 2024 program includes selective sampling across key alteration zones that were identified in the 2000 and

2023 drill programs. This comprehensive geochemical characterization will enhance the understanding of the alteration

domains controlling the gold distribution, a critical exercise in refining the exploration model and identifying potential drill

targets.

In addition, several promising zones will be prospected, including the Timiskaming-type conglomerate and its associated IP

anomalies, the Greco gold showing (1.04 g/t Au over 24.9 m in a channel sample), the Oswald gold showing (17.3 g/t Au

in a grab sample), and the gold Ankerite zone (see news release dated January 12, 2023).

Menarik Est:

Summer 2024 will mark Harfang’s first exploration program at Menarik Est. The Company has been conducting a

comprehensive historical data review, looking at geophysical surveys and data from more than 200 drill holes totalling

approximately 36,000 metres of drilling. The Menarik Est Zone hosts a non-NI 43-101 compliant resource of 6.34 Mt grading

7.73% Cr2O3, 398 ppb Pd and 105 ppb Pt (Figure 3).

The Summer 2024 exploration program is designed to verify the historical Ni-Cr-Cu-PGE occurrences and investigate several

high-priority areas within the ultramafic Menarik complex.

La Passe, Ewart, and Sakami:

The Company is planning a lithium targeted surface exploration program at La Passe, Ewart and Sakami. This program is

the logical sequence to the ongoing geoscience data review which also includes a pegmatite delineation exercise using newly

acquired satellite images.
