Harfang Exploration Inc. continues to deliver high grade gold on the Serpent Project

Highlights include:

• Grab samples up to 345 g/t Au from Trench TR-21-26;
• Channel samples up to 208 g/t Au over 0.75 m (Powerline showing);
• Quartz-tourmaline boulders (up to 45.5 g/t Au) up-ice of the Moby-Dick gold structure;
• Metallic sieve analyses up to 3,710 g/t Au for the coarse fraction (>106 microns) confirming the abundance of coarse-grained gold grains.

These results demonstrate the potential for high grade orogenic gold mineralizations along structures more than 7 km long straddling Harfang and LaSalle's properties (Fig. 2). Regional prospecting outlines potential for additional gold structures north and south of the Stu structure. Harfang carries with confidence its drill program in and around the marshland up-ice of the gold-in-till anomaly.

This press release discusses the most interesting gold occurrences from summer 2021.

1-Powerline showing
This gold occurrence, located in the northern part of the Property, returned up to 125 and 60 g/t Au from grab samples in 2020 (Figs. 1 and 3). The showing consists in decimetric to metric quartz veins hosted in a sheared tonalitic gneiss. Channel samples returned up to 208 g/t Au over 0.75 m and grab samples up to 296 g/t Au in 2021 (Table 1, Fig. 3). Visible gold is common in these quartz veins (Fig. 4) which extend up to 50 m laterally. Alteration minerals include sericite, K-feldspar and biotite. Up to 1% disseminated pyrite is locally present.

Summer prospecting in the northern part of the Property was successful with the discovery of several metric wide quartz veins and smaller quartz-tourmaline veins hosted in tonalitic gneiss and late intermediate to felsic intrusive rocks. Preliminary results from these veins include 12.55, 2.64 and 1.15 g/t Au (Fig. 1). These early encouraging results led to the addition of new claims by map designation in the northern part of the Property. Many analytical results are still pending.

2-Trench TR-21-26
This trench is located in the Moby-Dick and Tetras area (Fig. 2). A sub-metric quartz vein in shear zone returned up to 27.10 g/t Au over 0.60 m (channel) (Table 1). A grab sample with visible gold grains returned 345 g/t Au from that same vein (Fig. 5). The zone corresponds to a metric wide shear zone hosted in diorite and striking into a N030-040? direction. The Tetras shear zone, located 240 m to the southeast, returned local anomalous gold values with a maximum of 1.78 g/t Au over 0.55 m.

3-Quartz-tourmaline boulders Area
Four similar boulders scattered over a 20 m² site returned high grade gold values: 45.5, 13.25, 5.85, 3.97 g/t Au (Table 1, Fig. 6). These samples were collected as a follow-up on a gold-rich boulder (24.91 g/t Au) discovered at this site during fall 2020. The floats, sub-metric and angular in shape, may have been disintegrated from a larger and single boulder following freeze-thaw cycles. They consist in quartz veins with black tourmaline, actinolite, chlorite, magnetite, epidote, hematite and disseminated pyrite and traces of chalcopyrite. The floats are located near the junction between two structural lineaments oriented into N245? (Moby-Dick) and N305? directions. The latter structure contains discontinuous high grade gold up to 13.30 g/t Au over 0.65 m. Figure 6 also shows high gold grades obtained in the northeastern extension of the Moby-Dick structure (trench TR-20-05) during late 2020. That trench is located 45 m southwest of the quartz-tourmaline boulders.

Our summer exploration program included excavating of 26 mechanical trenching, detailed geological mapping and prospecting. A total of 599 channel samples and more than 560 grab samples were collected so far. Trenching was carried out in specific areas around the marshland where earlier prospecting had revealed large gold-bearing quartz veins and shear zones. Recent prospecting was focused on selected areas around the marshland and in the northern part of the Property. A soil survey (B-horizon) with more than 800 samples was completed. Results from these soil samples and approximately 250 grab samples are pending.

Harfang is actually drilling and conducting prospecting. More results will be released as they become available.

Harfang also announces the grant of 60,000 stock options to Vincent Dub?-Bourgeois, recently appointed director of Harfang. These stock options are granted in accordance with the terms of the stock option plan of Harfang. Each option entitles to purchase one (1) common share of Harfang at a price of $0.32 per common share for a period of ten (10) years from September 28, 2021.

Quality control

Rock samples discussed in this press release were sent to ALS (Val-d'Or, Qu?bec) to be analyzed for gold. Some of them were also analyzed for 33 other chemical elements. Gold was analyzed by atomic absorption following fire assaying on a 30-g sample fraction (Au-AA23). Other elements were analyzed using the four-acid ICP-AES method (ME-ICP61). Samples with >3 g/t Au were reanalyzed with a gravimetric finish (Au-GRA21). Metallic sieve analyses were done when >10 g/t Au following the Au-SCR21 procedure. Sample preparation and analytical determination were performed in various ALS laboratories.

The sampling procedures and the quality control followed protocols developed by Harfang and ALS. Preliminary data interpretation was done by Harfang.
