Building a mine takes 26 months minimum when done efficiently; cost estimation has wide ranges (±20-100%); capital costs post-pandemic have increased dramatically (Kotaneelee built for >$3B vs. Detour at $1.5B for similar scale); this uncertainty argues for smaller, higher-grade projects with faster payback and lower capital intensity.

“when people ask me how much it's going to cost to build a mine in in yellow knife I'll give you a number but it's plus or minus 20 to 100% right it could be between $200 to $400 million”
