Harfang Exploration Inc. announced the first results from the maiden winter 2021 drill program on its 100% owned Serpent Property ("Property") in James Bay (Québec). Drilling confirms at least one kilometric-scale auriferous structure in the marshland up-ice of the gold-in- till anomaly. This finding strongly supports the hypothesis that the source of gold grains in till and soil is proximal. This maiden drill program was successful as it reveals the existence of an extensive gold-bearing sheared corridor exceeding 1 km in length that connects with high-grade gold surface showings. This lineament confirms the hypothetical gold potential underneath the marshland. This press release discloses results from holes SER-21-001 to SER-21-013. So far, six out of 13 holes intersected gold intervals (Table 1; >0.30 g/t Au). SER-21-002 and SER-21-013, collared 740 m apart, returned the two most significant gold intervals with 1.44 g/t Au over 15.20 m and 3.47 g/t Au over 7.50 m (including 6.98 g/t Au over 3.20 m), respectively. These mineralized intervals are associated with a N285° magnetic discontinuity, along which SER-21-020, 023 and 027 have similar alterations and mineralizations linked to shear zones. Visible gold was observed in SER-21-002 and SER-21-027 (Fig. 4). Hole SER-21-002 also returned 47.10 g/t Au over 0.70 m (247 g/t Au in the coarse fraction by metallic sieve) at shallow depth under the 222.58 g/t Au quartz vein discovered in 2020. The eastern extension of this sheared corridor, underneath the marshland and east of SER-21-013, is unknown. All gold intervals intersected so far in drillholes remain open laterally and at depth. Analytical results are pending for the remaining 14 holes.Interestingly, the mineralized zone in SER-21-013 was intersected at the bedrock surface underneath the soil cover in the marshland suggesting that gold grains in glacial sediments (till and soil) are most likely proximal to the bedrock source (<500 m up-ice). However, none of the drillholes listed in this press release fully explains the gold-rich nature of the glacial sediments suggesting that other gold zones have yet to be discovered under the marsh. Gold intervals correspond to altered and sheared gabbro and quartz-bearing diorite locally associated with ultramafic (peridotite and pyroxenite) and felsic intrusive rocks. Alterations coeval with gold enrichment include minerals such as actinolite, biotite, chlorite, pyrite (<2%), calcite, tourmaline and quartz. Quartz veins are commonly associated with the gold grades. Scheelite occurs as an accessory phase and is not systematically related to gold. The mineralogical assemblage suggests upper greenschist to lower amphibolite facies which implies metamorphic conditions similar to those in most orogenic gold deposits.
