The Klaza property covers an area of 25,000 hectares (61,776 acres) and is just 50 kilometers (31 miles) west of Granite Creek's Carmacks deposit.
Rockhaven Resources Ltd. March 16 announced the final assay results from the 2021 exploration program at its road-accessible Klaza property, located in the Dawson Range Gold Belt in southern Yukon, Canada.
A 2020 preliminary economic assessment for Klaza outlines plans for a mine that would produce roughly 750,000 ounces of gold and 13.8 million oz of silver over 12 years.
After drilling a total of 14,256 meters in 72 holes during the summer and fall of 2021, the last batch of assays to roll in contain the remaining 10 holes that tested the Rusk zone, a new vein complex that was discovered through diamond drilling in 2020.
"The 2020 and 2021 drill results from the Rusk Zone have identified a broad mineralized corridor that is over 300 meters long and is open for expansion along strike and to depth," said Rockhaven Resources CEO Matt Turner. "Rusk has received only a small fraction of the total drilling completed at the Klaza deposit to date and may have positive implications for the scope and timing of the potential development at Klaza."
All the 2021 drill holes from the Rusk structure returned significant mineralization, highlights include:
• 2.26 meters averaging 5 grams per metric ton gold and 336 g/t silver in hole KL-21-523.
• 5.42 meters averaging 3.1 g/t gold and 62 g/t silver in hole KL-21-542.
• 5.32 meters averaging 2.2 g/t gold and 69 g/t silver in hole KL-21-559.
• 8.72 meters averaging 1.2 g/t gold and 20 g/t silver in hole KL-21-560.
• 6.73 meters averaging 1.1 g/t gold and 56 g/t silver in hole KL-21-558.
The Rusk zone lies just 3,000 meters southeast of the main resource area at Klaza and was first identified through soil geochemical sampling and geophysical surveys.
The maiden drill program in 2020 confirmed the presence of a new vein complex, with numerous high-grade gold, silver, lead, and zinc veins discovered in a fence of holes drilled across the 2.6-square-kilometer (one square mile) multi-element soil geochemical anomaly.
The company states the mineralization and controlling structures at Rusk generally resemble those at other zones found in the Klaza deposit but also contain proportionally more silver and less gold on average.
"Additional drilling is planned to further evaluate the Rusk zone in 2022," finished Turner.
