How this model works

Dry mass = wet mass × (1 − moisture). Contained Cu = dry mass × assay. Payable Cu = contained Cu × payability. Gross value = payable Cu × assumed USD/t price.

Treatment = dry mass × USD/dmt charge. Refining = payable tonnes × 2,204.62262185 lb/t × US cents/lb / 100. Freight = dry mass × entered USD/dmt. Modeled value = gross − treatment − refining − freight. Negative charges act as credits.

All percentages are fractions in calculations. Defaults are arithmetic examples, not reported market terms. Actual contracts may use minimum deductions, pricing periods, penalties, by-product credits and assay settlement rules. The result excludes those items and is not net profit.
