My notes have EU at US$45/lb AISC (that's from April 16th BBN interview).
450-500k oz corporate production, 2024, which brings them to cash-neutral productoin rate by end of year (Goranson). Then 1 million ounce/year rate by end of 2025, and 2.4 million ounce per year by end of 2026.
Assuming US$30/pound cash flow, that puts EU at 8.6 EV/annual AISC margin, before the Wyoming/SD operations start up.
