The Preliminary Economic Assessment (PEA) for the Whistler Gold-Copper Project estimates an after-tax Net Present Value (NPV5%) of $2.04 billion and an Internal Rate of Return (IRR) of 33.0%, with an initial payback period of 2.1 years, using base case prices of $3,200/oz Au, $4.50/lb Cu, and $37.50/oz Ag. At spot prices of $5,000/oz Au, $5.85/lb Cu, and $70/oz Ag, the estimated after-tax NPV5% increases to approximately $4.88 billion with an IRR of 62.0% and an initial payback of 1.2 years. Average annual production is estimated at 345,000 ounces of gold equivalent (AuEq) per year during the first three years of operations, with a total life of mine (LOM) production of 3.6 million ounces AuEq over a 14.6-year mine life. LOM production comprises 2.6 million ounces gold, 6.9 million ounces silver, and 592 million pounds copper. The estimated All-In Sustaining Costs (AISC) are $1,046/oz Au (by-product basis), and initial capital costs are projected at $1.28 billion. The project contemplates an open-pit truck-and-shovel operation with conventional process methods at a nominal throughput rate of 40,000 tonnes per day (tpd), recovering 88.9% gold and 77.8% copper. The PEA is based on indicated mineral resources at the Whistler Deposit, which is one of three known gold-copper deposits at the Project with existing mineral resources. The State of Alaska, through Governor Mike Dunleavy, expressed commitment to advancing the West Susitna Access Road, which is expected to directly connect Whistler with existing transportation and energy infrastructure.
