Page "Mining" Paragraph 38

This is when the mining company makes the decision to develop the mine or to walk away from the project.

This includes mine planning to evaluate the economically recoverable portion of the deposit, the metallurgy and ore recoverability, marketability and payability of the ore concentrates, engineering concerns, milling and infrastructure costs, finance and equity requirements and an analysis of the proposed mine from the initial excavation all the way through to reclamation.

The proportion of a deposit that is economically recoverable is dependent on the enrichment factor of the ore in the area.
