ProspectOre is an economic idea: rock you can mine at a profit.
DrillGrade × width beats a flashy grade. Check true width.
EstimateInferred → Indicated → Measured; reserves need modifying factors.
PermitStudies and multi-season baselines, funded by equity or a JV partner. Value often sags here.
FinancePermits first, then project debt and FID. Lenders and investors weigh NPV and AISC.
MineCut-off grade sorts ore from waste; strip ratio drives cost.
ProcessOunces = tonnes × grade × recovery ÷ 31.1.
ReclaimClosure is planned and bonded before mining starts.
