Harfang Exploration Inc. reported the final results of the winter 2021 drill program on its 100% owned Serpent Property (“Property”) in Eeyou Istchee James Bay (Québec). These latest results better define the Stu structure and suggest the existence of a northern parallel gold-bearing structure underneath the marshland. Harfang is preparing with confidence the second drilling phase on the Property to start in August. Highlights: Up to 3.61 g/t Au over 5.90 m, including 8.87 g/t Au over 2.05 m (visible gold), in SER-21-017 (northern structure); All drillholes located along the southern structure intersected gold intervals (up to 2.55 g/t Au over 4.00 m); A 2,500 m summer drill program will test both gold-bearing structures and other first-priority targets (for instance Moby-Dick, 7.78 g/t Au over 6.15 m). Drilling strategy: The company's first drilling campaign (4,336 m, 27 holes) was designed to test hypothetical near-surface gold mineralizations that could be the sources from which gold grains accumulated in great abundance in till and soil to form the large (>8 km2) gold-in-till anomaly. Drillholes were positioned 1) to test isolated first-priority targets, and 2) along a north-south fence oriented perpendicular to the main interpreted structures in the marshland. This press release discloses results from holes SER-21-014 to SER-21-027 (Figs. 2 and 3). Nine out of these 14 holes intersected gold intervals . See press release dated on May 20, 2021 for initial drilling results (SER-21-001 to SER-21-013). Drilling results: Previously-disclosed drilling results highlighted the existence of a kilometer-scale gold structure linking holes SER-21-002 and SER-21-013, and gold showings at surface (Fig. 2). This structure, oriented into a N285° direction, has been successfully intersected in SER-21-014, 020, 023 and 027. Significant mineralized intervals in these holes include: SER-21-014: 0.79 g/t Au over 3.00 m; SER-21-020: 1.07 g/t Au over 6.70 m, 0.67 g/t Au over 6.10 m, 3.81 g/t Au over 1.95 m; SER-21-023: 5.56 g/t Au over 1.50 m; SER-21-027: 2.55 g/t Au over 4.00 m. Hole SER-21-017 intersected 3.61 g/t Au over 5.90 m (including 8.87 g/t Au over 2.05 m) between 190.20 and 196.10 m (core depths). This interval suggests that a northern gold-bearing zone, probably parallel to the Stu structure, is present underneath the marsh. The shallower gold interval in SER-21-023, grading at 4.51 g/t Au over 1.80 m, could be part of that northern structure. Visible gold was observed in SER-21-002, 017 and 027. Nine holes (SER-21-009 to SER-21-017) were drilled along a north-south 770 m long fence up-ice of the highest gold values in tills and soils. Interestingly, 7 of these holes intersected gold intervals with a metal factor above 1 demonstrating the abundance of mineralized structures that still need to be drill-tested in the area. Figure 3 shows that the prospective zone might correspond to a deformation corridor (Stu Structural Domain) defined by N285° and N245° structures. Gold intervals correspond to altered and sheared gabbro and quartz-bearing diorite, and associated quartz veins. Alterations coeval with gold enrichment include minerals such as actinolite, biotite, chlorite, pyrite (<2%), calcite, tourmaline and quartz. Mapping confirmed that the diorite/gabbro intrusion, considered as a favourable gold metallotect, covers a 8 km x 2 km area extending well-beyond the actual drilling footprint. Again, Harfang believes that none of the holes drilled so far fully explains the gold-rich nature of the glacial sediments, suggesting that other gold zones have yet to be discovered underneath the marsh. Summer exploration program: Harfang is conducting its fully-funded summer exploration program and an important trenching campaign is under way in the immediate area of the drillholes. Trenching will provide a better understanding of geological features and possibly expose at surface gold intervals intersected in drillholes. A recent structural interpretation arising from a new LiDAR survey flown over the Property is a valuable tool for our field crew in identifying potential mineralized lineaments. Additional prospecting and geochemical surveys (till and soil), which proved to be of great help in positioning drillholes, are also part of our program. A second drill program (approximately 2,500 m) is planned for mid-August. It will be carried out using a heliportable rig that will test several first-priority targets, extend the kilometric gold-bearing structures intersected in drillholes and test additional gold-bearing lineaments at the property scale, including Moby-Dick.
