Snowline Gold Corp. (CSE:SGD) has announced additional preliminary assay results from its 2022 drilling program at its Rogue Project in Yukon.
A key highlight was hole V-22-029, which intersected sheeted quartz vein mineralization within the Valley intrusion averaging 1.26 grams per ton (g/t) gold (Au) over 558.7 metres (m) from surface, including 2.04 g/t Au over 202m, with additional mineralization at depth.
Snowline said the hole was collared at a 207m step-back perpendicular to strike from hole V-22-010 (318.8m at 2.55 g/t Au from surface) to test the local width of Valley’s near-surface, well-mineralized corridor and the continuity of mineralization to depth.

“V-22-029 exceeded our expectations, intersecting strong mineralization much higher in the hole than we originally anticipated and continuing to significant depth,” Snowline CEO and director Scott Berdahl said in a statement. “It’s the longest continuously mineralized interval we’ve drilled at Valley to date, and like many of Valley’s best holes the interval begins at bedrock surface.”
Visual results indicate the presence of a large central zone within the broader Valley intrusion bearing higher vein densities, the company said. Initial analytical results for this zone consistently carry unusually high grades for a reduced intrusion-related gold system.
“For perspective, I invite anybody visiting Toronto for PDAC to look at the CN Tower, which stands 553.3m tall, just shy of the length of this mineralized interval,” Berdahl added. “The scale, grade and continuity of the gold system at Valley continue to impress us, and we look forward to additional results.”
The company noted that the hole extends the known width of near-surface, at greater than 1 g/t Au mineralization at Valley, and demonstrates the continuity of mineralization to depths greater than 400m below surface.
As with previous holes at Valley, Snowline said, gold grades are carried across broad intervals, and they are not heavily affected by local high-grade (greater than 10 g/t Au) intersections.
Rogue's Valley Zone is a newly discovered, bulk tonnage style, reduced intrusion-related gold system (RIRGS), with geological similarities to multi-million-ounce deposits currently in production like Kinross's Fort Knox Mine in Alaska and Victoria Gold's Eagle Mine in the Yukon.
The early drill results demonstrate unusually high gold grades for such a system present near-surface across intersections of hundreds of metres, the company said, noting that gold is associated with bismuthinite and telluride minerals hosted in sheeted quartz vein arrays along the margins of and within a one-kilometer-scale, mid-Cretaceous aged Mayo-series intrusion.
Snowline Gold is a Yukon Territory-focused gold exploration company with a seventeen-project portfolio covering more than 280,000 hectares. The company is exploring its flagship more than 137,000-hectare Rogue and Einarson gold projects in the highly prospective yet underexplored Selwyn Basin.
