Valuation of similar deposits

When looking at the grade-tonnage curves for a given type of orebody, can we infer its worth from that of similar deposits?

Not necessarily. The orebodies might occur at different depths, have different shapes, continuity, mineralogy, and ground conditions, and the location might be different. All these factors have an influence on the choice of the mining methods, the processing, and the concentrates for sale. This in turn has an impact on the cut-off grades, the size of the operations, the production rates, the capital costs, annual revenues, and operating costs.
