CuEq Metal Equivalent Calculator for Mining Results

Metal equivalent calculations are often used to compare similar deposits with slightly different metal ratios: CuEq (copper equivalent) and AuEq (gold equivalent) are most common in copper porphyry deposits. Silver equivalent (AgEq) may be used in a silver mine with lead and zinc or other base metal credits. A nickel deposit may have PGE, gold or other minor constituents.

Use this simple metal equivalents calculator to calculate common (and uncommon) equivalences. For each metal select the grade and the market price to be used in the calculations. You may also select a recovery %, the amount of assayed material that can actually be recovered during processing of the ore.

When using the calculator be sure to select the appropriate pricing units (oz. or lbs.) and the assay units (% or grams per tonne). You can calculate Eq for up to 5 precious or base metals using this calculator. Note that g/t is the same as ppm.
