Vancouver — Initial metallurgical test work on the High Lake base metal deposit in Nunavut has returned higher than expected copper recoveries for owner Wolfden Resources (YWO-V).
The tests were completed by Lakefield Research. Two surface samples were combined with core samples in each of the two main zones.
In the A/B zone, the sample averaged 6.21% copper, 1.49% zinc, 47.1 grams silver and 0.64 gram gold per tonne. Flotation recoveries came in at 95% for copper, 90% for gold and 70% for silver, going into a 30% copper concentrate. In a 50% zinc concentrate, 70% of the zinc was recovered.
In the D zone, the sample graded 3.15% copper, 6.21% zinc, 103 grams silver and 0.33 gram gold. Flotation recoveries showed that 80% of the zinc goes into a 50% zinc concentrate. For the minor metal, copper recoveries hit 90%, together with 90% of the gold and 70% of the silver.
“The company is very pleased that no contaminants are associated with the High Lake ore,” says Ewan Downie, Wolfden’s president.
The spring breakup forced Wolfden to suspend drilling on the deposit after four holes. Assay results are expected within 10 days. The company expects to complete an additional 10-15 holes later this year.
The project is located 45 km south of Coronation Gulf in Nunavut.
The junior recently acquired a 100% stake from Aber Diamonds (ABZ-T) and Kennecott Canada. Wolfden issued Aber 250,000 units for its 20% interest. Each unit consists of one common share and one warrant. Each warrant is exercisable at $1.50 in the first year and the price increases by 25 per year over a 5-year period. Kennecott was paid 800,000 units for its 80% stake.
At last count, High Lake contained 5.3 million tonnes grading 4.05% copper, 2.36% zinc, 1.76 grams gold and 31.73 grams silver.
