Harfang drills and confirms a kilometric-scale gold structure at James Bay,

May 21, 2021


Harfang Exploration Inc. has announced the first results from the maiden winter 2021 drill program on its 100% owned Serpent Property in James Bay. 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.

Highlights

  • Up to 3.47 g/t Au over 7.50 m, including 6.98 g/t Au over 3.20 m, at the bedrock surface underneath the marshland in drillhole SER-21-013;
  • 47.10 g/t Au over 0.70 m and 1.44 g/t Au over 15.20 m in drillhole SER-21-002;
  • Visible gold observed in drillholes SER-21-002 and SER-21-027;
  • Discovery of a gold structure striking N285° and exceeding 1 km in length.

Our strategy

The scout diamond drill program, carried out during winter 2021, totaled 4,336 m in 27 holes on and up-ice of the richest gold till and soil samples (Fig. 2). In addition to drilling, Harfang completed an Induced Polarization (“IP”) survey along lines spaced 100 m apart covering 67.1 linear km in the same area. The drill program was designed to test potential near-surface gold mineralizations that could be the sources from which gold grains accumulated in till and soil. Our strategy was to drill: 1) isolated first-priority targets, and 2) a series of holes aligned perpendicular to the main structures mapped in the area. Drillholes were carefully positioned taking in consideration many parameters such as proximity of gold-rich till, soil and showings, mapped and/or interpreted structural corridors, interpreted features from the magnetic map and IP anomalies (chargeability and resistivity).

Our results

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) (Fig. 3), 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.
