Last updated 1/24/2018 at 11:59am
Rockhaven Resources Ltd. is enjoying support from Coeur Mining Inc. at Klaza, a road accessible gold-silver project in southern Yukon.
Coeur, which owns the Kensington gold mine about 225 miles (363 kilometers) south of Klaza, participated in a Rockhaven financing and its technical team is assisting Rockhaven as it advances exploration, engineering and metallurgical studies for Klaza.
A 2016 preliminary economic assessment for Klaza envisions using a combination of open-pit and underground techniques to mine the 9.42 million metric tons of inferred resource grading 4.48 grams per metric ton (1.36 million ounces) gold, 89.02 g/t (26.96 million oz) silver, 0.75 percent (155.4 million pounds) lead and 0.95 percent (197.8 million lbs.) zinc.
A 1,500-metric-ton-per-day process plant is projected to produce 630,000 oz gold, 11,364,000 oz silver, 52.46 million lbs. zinc and 51.23 million lbs. lead over an initial 14-year mine life.
Since the completion of the PEA, Rockhaven has focused on further metallurgical work, resource expansion and infill drilling to enhance the economics of mining Klaza.
The 2017 program included 15,922 meters of drilling focused on defining and expanding the near-surface resources in the BRX and Klaza zones.
Highlights from 2017 drilling include 0.61 meters of 182 g/t (5.85 oz/t) gold and 231 g/t silver, and 2.92 meter of 7 g/t gold and 7.12 g/t silver; 6.94 meters of 4.18 g/t gold and 30.1 g/t silver; 2.9 meters of 7.57 g/t gold and 65.6 g/t silver; and 1.93 meters of 14.14 g/t gold and 116 g/t silver.
The 2017 program also included exploration drilling to test geophysical and geochemical targets near the deposit.
Material collected from the resource area is being used for additional metallurgical and pre-concentration test work to optimize processing, reduce costs and lower cut-off grades.
"We look forward to rapidly advancing the Klaza project with the help of Coeur Mining's technical team," said Rockhaven President and CEO Matt Turner.
Rockhaven is a member of the Strategic Exploration Group, a collection of junior resource companies focused on exploring northwestern Canada. Members of the group enjoy a close working relationship with Archer, Cathro & Associates (1981) Ltd., a geological consulting firm with extensive knowledge and exploration expertise in the Yukon Territory and northern British Columbia.
