Snowline Gold Corp. (CSE:SGD) has announce additional positive preliminary assay results from its 2022 drilling programme at the Valley Zone, Rogue Project, Yukon.
Notably, hole V-22-032 intersected a zone of sheeted quartz vein mineralization within the Valley intrusion averaging 1.72 g/t Au over 207.0 m within a broader mineralized zone averaging 1.32 g/t Au over 338.0 m. The entire hole, including barren sections, averaged 0.93 g/t Au across 532.7 m, ending in mineralized rock.
The hole was collared 166 m from any other hole and drilled northeast to test the system between previously announced V-22-005 (192.0 m @ 1.52 g/t Au) and V-22-010 (318.8 m @ 2.5 g/t Au).
“The latest results from Valley continue to demonstrate substantial scale and strong grades for a reduced intrusion-related gold system,” said Scott Berdahl, CEO and Director of Snowline.
“Holes V-22-015 and 032 add considerably to the known tonnage of well-mineralized rock in Valley’s central zone. The shape, the size, and the distribution of grades that we’re seeing at Valley-with many of the highest grades encountered to date starting at surface-bode very well for the potential economics of the discovery.
“We eagerly await remaining 2022 assay results and their contributions to our understanding of this large mineralized system, with more than 5,000 m still to come at Valley and all five holes (>2,000 m) still pending from our nearby Gracie target.”
Visual results indicate the presence of a large central zone within the broader Valley intrusion bearing higher vein densities. Initial analytical results for this zone consistently carry unusually high grades for a reduced intrusion-related gold system.
V-22-033 expands the known width of the mineralized zone locally to >300m. While broad zones of continuous mineralization were not encountered at depth in this location, local intervals were. The deepest >1 g/t Au assay ran 1.2 g/t Au over 1.5 m from 672.5 m downhole. Views look northwest.
V-22-015 was drilled to test the relatively high-grade mineralization encountered in V-22-014 and V-22-007 across a wider width and at depth. Views look northwest.
everal zones of higher grades are present but capping these at 10 g/t Au shows that the intervals are carried by robust mineralization along large zones within these higher-grade holes.
Hole V-22-032 was collared in hornfels sedimentary rock west of the Valley intrusion, and drilled northeast, roughly perpendicular to the general southwest orientation of most drill holes to date at Valley. On crossing into the intrusion at 91.6 m downhole, it averaged 1.32 g/t Au over the subsequent 338.0 m, with a general increase in grades towards a gradational boundary between intrusive phases encountered at 341.5 m downhole. The 100.5 m above this boundary averaged 2.03 g/t Au, including a 20 m stretch near the boundary averaging 4.19 g/t Au.
The hole demonstrates further continuity of near-surface, gram to multiple gram per tonne gold mineralization encountered in previous holes at Valley. The darker, porphyritic phase of the intrusion below the boundary may be a driver for higher grades in the lighter, medium-grained granodiorite above.
As with previous holes at Valley, gold grades are carried across broad intervals, and they are not heavily affected by local high-grade (>10 g/t Au) intersections.
Hole V-22-015 was collared in the Valley intrusion on section with V-22-007 (410.0 m @ 1.89 g/t Au including 146.0 m @ 3.24 g/t Au) and V-22-014 (285.2 m @ 1.45 g/t Au including 128.2 m @ 2.48 g/t Au), stepped back roughly 182 m from V-22-007 to better test the width and depth of the system. V-22-015 encountered its highest grades within the upper two thirds of the hole. A broad zone of high quartz vein density encountered lower in the hole loosely correlates with zones of the same darker, porphyritic phase of the intrusion seen in V-22-032.
The abrupt decrease in vein density at the intrusive phase boundary observed in that hole is thus not present in V-22-015. Instead, a decrease in the regularity of bismuthinite and visible gold in the lower parts of V-22-015 compared to veins seen roughly 200 m vertically above in V-22-007 appears to correspond to a decrease in gold values.
