Greens Creek's total cost of sales outlook is reiterated at $289 million (includes non-cash depreciation expense) and cash cost at ($7.00)-($5.75) after by-product credits, per silver ounce, and AISC at ($1.00)-$0.50 after by-product credits, per silver ounce. 3,4 Capital investment guidance is lowered to $45-$47 million in sustaining capital and $2-$5 million in growth capital from the prior $48-$51 million and $10-$12 million, respectively. Capital investment at Greens Creek is expected to increase in the fourth quarter, compared to the third quarter, due to ongoing projects and commencement of work on the dry stack tailings expansion project.
