Recovered Metal Value at 59% payable assay or recovery share: a worked example

Suppose payable assay or recovery share falls to 59%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate payable recovered metal value from recovered metal mass, price per kg, payable assay or recovery share, and fixed lot value adders.

The inputs for this scenario

  • Recovered metal mass: 4,200 kg (held at the documented default)
  • Metal value per kg: 18.5 $ / kg (held at the documented default)
  • Payable assay or recovery share: 59 % (the input this scenario stresses; the baseline uses 82)
  • Fixed premium or lot value adder: 3,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Payable metal value = recovered metal mass × metal value per kg × payable assay or recovery share.
  • Estimated recovered metal value works out to 49,343 $ at these inputs, and this is the headline figure for the scenario.
  • Recovered value per kg works out to 11.75 $ / kg at these inputs.
  • Payable metal value works out to 45,843 $ at these inputs.
  • Fixed premium or lot value adder works out to 3,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where payable assay or recovery share sits at 82% and the headline result is 67,214 $, this scenario comes in 26.59% below the baseline at 49,343 $.
  • It computes estimated recovered metal value by applying a payable assay or recovery share to mass times price, then adding a fixed lot premium. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Estimated recovered metal value: 49,343 $ (headline result)
