NPV Hard to find anything current on NPV for Pumpkin Hollow.
This is from 2018, so factor in 2018 CU price, and expenses from then as well.
"On Monday, the company delivered results of a preliminary economic assessment (PEA) for a standalone openpit development option, which returned strong project economics, including a pretax net present value (NPV) of $1.17-billion and an internal rate of return (IRR) of 21%. The post-tax NPV came to $927-million and the IRR to 19%."
Thats just the open pit, without the 2018 and after drilling.
