Harfang Exploration Inc. ('Harfang') (TSX-V: HAR) is pleased to report partial results from the mechanical trenching and prospecting summer program at its 100% owned Serpent Property ('Property') in James Bay (Quebec).

During summer 2020, Harfang executed a vast exploration program at Serpent where most efforts were made in an unexplored part of the Property highlighted by a >4 km2 gold-in-till anomaly (see press release dated January 16, 2020). Performed work includes an induced polarization survey (34 linear km), 14 mechanical trenches in three specific areas (Moby-Dick, Ana and Sasquatch), and collecting of 855 grab, 458 channel, 90 till and 50 soil (B-Horizon) samples. Recent fieldwork revealed more than 20 new gold showings (>1 g/t Au). Combined with the previously discovered showings (2017-2019), gold occurrences are now known over an East-West strike length of at least 12 km (Figs. 2 and 3). Mechanical trenching was carried out on three extensive and auriferous quartz vein-filled shear zones: Moby-Dick, Ana and Sasquatch. Located 100 m from the exploration camp, the Moby-Dick structure was channelled and returned up to 7.78 g/t Au over 6.15 m, including 24.06 g/t Au over 1.80 m and 2.00 g/t Au over 2.25 m (Figs. 4 and 5). Visible gold was observed in one sample along this channel (61.06 g/t Au over 0.50 m). Trenching conducted on this structure exposed the vein over more than 350 m. The easternmost part of the structure returned 8.95 g/t Au over 0.45 m (TR-SER-20-005). Gold content in other channels is limited to anomalous values showing its coarse nature (nugget effect). Grab samples returned up to 12.27 g/t Au (TR-SER-20- 001), and 8.85 g/t and 2.10 g/t Au (TR-SER-20-007). The Moby-Dick structure is characterized by shear zone-hosted quartz veins up to 10 m wide. It stretches over a strike length of at least 350 m in a N250-degree direction, dipping moderately to abruptly to the northwest. The Ana structure is characterized by a 4 m wide shear zone filled with quartz veins exposed over 25 m long (Figs. 6 and 7). The shear zone strikes into a N245-degree direction and dips abruptly to the northwest. It is developed in the old Archean tonalitic basement (Langelier Complex) and pyroxenite and gabbro dykes. The shear zone appears to continue to the northeast. Grab samples reached up to 23.14 g/t Au in the most mineralized part of the shear zone where visible gold was observed (Fig. 6). Channel sampling results are pending. Sulfide content (pyrite, +/- pyrrhotite) reaches up to 5% locally. Calc-silicate and potassic alterations are described together with intense silicification. A parallel structure is located 25 m to the southwest. The Sasquatch structure is located 3.8 km northwest of Moby-Dick. It is characterized by an 8 m wide shear zone filled with quartz veins striking into a N245-degree direction, dipping abruptly to the northwest (Figs. 8 and 9). Its lateral extension is at least 80 m and remains open at both extremities. A grab sample collected in a portion of the vein with 3-5% pyrite returned 1.20 g/t Au. Channel sampling results are pending. Sheared pyrite-bearing gabbro and several smaller quartz veins, which graded 3.50, 5.31, 9.29 and 222.58 g/t Au, were found southeast of Sasquatch along potential parallel structures. Both Moby-Dick and Sasquatch structures are hosted in gabbro and quartz-bearing diorite. Potassic (biotite) and calc-silicate (actinolite+/-chlorite) alterations accompany silica flooding. Sulfide content is heterogeneous with the most mineralized portions containing up to 3-5% pyrite and traces of chalcopyrite. Harfang considers that an important East-West structure (called the 'Stu Structure') and its ENE-WSW secondary structures affecting the geological units in the gold-in-till anomaly area represent the first priority target for additional exploration. Field evidences such as gold anomalies in bedrock and till, structural features and mapped alterations support this interpretation. Fieldwork has outlined a strong gold potential along various structures. The fall program is already underway and our team is enthusiastic about the recent results. Harfang's employees operate under a COVID-19 management and mitigation plan. The field crew will continue surface prospecting and proceed to an important soil (B-Horizon) program around the swampy area which partially covers the first priority target (Fig. 7). A heliportable excavator will be used to realize test pits and trenches in specific areas in and around the swamp.
