DDH CRO-22-127ext, intersected multiple mineralized zones, including 1.33 g/t Au over 16.80 metres starting at 375.20 metres including 3.25 g/t Au over 3.5 metres, and 1.29 g/t Au over 9.40 m, starting at 285.00 metres, including 5.16 g/t Au over 2.00 m (approximately 250m east of CRO-22-150 and 128); DDH CRO-22-128 returned 1.32 g/t Au over 12.50 metres starting at 237.25 metres including 6.58 g/t Au over 1.00 metre (on strike of CRO-22-150 and 127Ext); DDH CRO-22-147 returned 1.31 g/t Au over 13.30 metres starting at 220.00 metres, including 3.56 g/t Au over 2.90 metres; Numerous gold values in step-out drilling of the mineralization discovered in 2022 in CRO-22-120, highlighted by hole CRO-22-137, which intersected 12.82 g/t Au over 1.9 metres starting at 63.10 metres, including 40.30 g/t Au over 0.60 metres; DDH CRO-22-135, drilled between the
This program was designed to test
The discovery area associated with the
Targets within the North Basalt Domain (' NBD ') consisting of extensive carbonate-sericite alteration in surface trench exposures and RC bedrock chips supplemented by gold grains in till anomalies from a rigorous Reverse circulation (RC) drill program completed in late 2021 and early in 2022.
DDH CRO-22-128 returned 1.32 g/t Au over 12.50 metres and hole CRO-22-127 was extended to test for the possible strike extension of this mineralization and intersected wide zones of carbonate-sericite-fuchsite-pyrite +/- silica-albite alteration, returning 1.29 g/t Au over 9.40 metres, 0.73g/t Au over 6.15 metres and 1.33 g/t Au over 16.80 metres. This mineralization remains open at depth to the east for at least 400 m.
Hole CRO-22-150 was drilled approximately 100 metres down dip of hole CRO-22-128. The hole encountered the same sequence of pillowed mafic volcanics and massive gabbros, affected by wide zones of strong sericite-carbonate-pyrite alteration, with local fuchsite and sections of strong albite-silica alteration, accompanied by quartz-pyrite veins interpreted to be hosted in hyaloclastite zones, in contact with gabbro. Results include 1.66 g/t Au over 21.55 metres (including 3.20 g/t over 2.00 metres and 4.87 g/t Au over 4.65 metres) and 10.94 g/t Au over 7.00 metres (including 16.15 g/t Au over 4.60 metres), 9.05 g/t Au over 1.0 metre, 1.26 g/t Au over 7.15 metres (including 2.70 g/t Au over 2 metres) and 0.53 g/t Au over 11.5 metres.
Hole CRO-22-151 was drilled 100 metres down dip of CRO-22-127ext, and hole CRO-22-152 was drilled to test mineralization along strike between CRO-22-128 and CRO-22-127ext. These holes both cut the basalt/gabbro sequence and wide zones of strong sericite-carbonate-pyrite +/- silica and fuchsite alteration. Several anomalous gold values were intersected including 1.65 g/t Au over 5.00 metres in CRO-22-151 and 2.03 g/t Au over 6.50 metres in CRO-22-152.
Mineralization in this western area has now been found along a strike length of approximately 450 metres and is open along strike in both directions and at depth. The results obtained to date in the NBD suggest that a large gold-bearing hydrothermal system is present, at least 1,400 metres long and 300 metres wide. Drilling has been largely exploratory, with holes approximately 100 metres apart, except for the Z120 area. Most of the NBD remains to be drill tested. The Company is currently evaluating the next phase(s) of exploration for this area.
Holes CRO-22-131 and 132 tested the east and west extents of the historic Croteau-Est Showing, which does not appear to have been previously drilled. Channel sampling at this showing by Northern Superior in 2012 returned gold values up to 4.83 g/t Au over 0.70 metres. The showing occurs on the north side of an area of low magnetic intensity, found to be coincident with carbonate-sericite alteration and quartz veining, which returned 4.37 g/t Au over 2.00 metres in hole CRO-22-131 . Based on the geology and alteration present in these holes, CRO-22-135 was drilled directly beneath the Croteau-Est Showing and returned 5.13 g/t Au over 3.05 metres, within similarly altered material.
Holes CRO-22-137 through 148 tested the Z120 zone, found in holes CRO-22-120 (1.06 g/t Au over 26.30 metres, including 4.98 g/t Au over 3.00 metres) and CRO-22-114 (0.40 g/t Au over 19.25 metres). This work has successfully extended mineralization approximately 400 metres along strike to the east. Unfortunately, wet ground conditions prevented testing the zone to the west. The zone is interpreted to dip moderately to the south and appears to cross-cut local stratigraphy. Highlights of the drilling in this area include 12.82 g/t Au over 1.9 metres including 40.30 g/t Au over 0.60 metres in hole CRO-22-137, 0.67 g/t Au over 16.80 metres in CRO-22-141 and 1.31 g/t Au over 13.30 metres in CRO-22-147. This zone remains open along strike and at depth.
CRO-22-149 was designed to test a grassroots target, where feldspar porphyry dykes intersect the interpreted Gwillim Fault. The hole encountered mafic volcanics intruded by feldspar porphyry dykes and sericite-carbonate alteration zones, which returned 1.87 g/t Au over 1.00 metre and 5.61 g/t Au over 1.50 metre.
