Gold Equivalent (AuEq) is a popular term used in the mining industry to describe the value of a mineral deposit when taking into account other metals present such as silver, copper, or zinc. While gold equivalent is the most commonly used term, it can also be referred to as Metal Equivalent (ME), Silver Equivalent (AgEq), or Copper Equivalent (CuEq) depending on the primary metal present in the deposit. These terms allow mining companies to compare the value of different deposits with varying mineral compositions and help investors understand the true potential of a mining project. Ultimately, no matter the term used, the value of a deposit is determined by the sum of the metals present in the ground.
