The final highlight of the winter drilling was obtained in our very last hole of the program, NO-21-12, which returned 6.02 g/t Au over 2.5 m in Zone 1.
The discovery area is located within an under-explored portion of the Casa-Berardi-Douay-Cameron deformation zone which host the Casa Berardi gold mine (actual gold producer) and the
A total of 5,104 metres in 12 holes were drilled on the property this winter. Holes NO-21-01 to NO-21-08 and NO-21-12 were drilled in the vicinity of the two successful holes drilled in 2020, at 50 m spacing to the east and below the latter. Holes NO-21-09 to NO-21-11 were drilled on IP anomalies in the eastern portion of the property. All results from the winter drilling program have been received and compiled.
The Main mineralized zone (Zone 1) strikes in an east-west direction and dips steeply to the south. So far, it has been recognized for over 600m laterally and from surface down to 350m. Its true thickness varies from 0.5m to 10m with an average of approximately 3-4m. The geometry of the mineralized zone is noticeably simple and continuity is excellent. Zone 1 appears to be spatially related to a narrow unit of oxide Iron Formation (2-3m thick). Most mineralized intercepts consist of a silicified stockwork of quartz and sulphides (pyrrhotite, pyrite and arsenopyrite). Best gold grades are associated with sulphide rich intervals. This zone could be, at least in part, related to replacement of the iron oxides by iron sulphides. In most instances, Zone 1 is located within a competent greywacke unit which is not broken up or sheared. Unreleased results from Zones 1 and 2 are from holes NO-21-07, 08 and 12
Zone 2 is a gold anomalous tabular body located some 40 m to the north of Zone 1. At this stage, it is of limited economical interest.
A preliminary observation about the genesis of this gold deposit is that it appears that the presence of oxide facies bedded Iron Formation (BIF) is necessary to mobilize the gold. The presence of a strong quartz-sulphide stockwork without BIF (like the one observed in hole NO-21-07) is not sufficient to attract and retain the gold flowing through the hydrothermal system. Although not all BIF's are associated with gold anomalies, they remain a good exploration tool for future drilling programs.
BIF's are lenticular sedimentary units. They can disappear laterally and vertically and reappear not too far away. This is what we observe in the eastern part of Zone 1 where the BIF is absent in holes NO-21-07 and 08 and reappears in hole NO-21-03. If this is confirmed, this deposit could comprise many zones.
