Glossary

Iron-free metals and alloys. In general, they are soft and have little mechanical resistance, so that they are combined with other metals (alloys) to modify their properties.

Concentration of a desired mineral in a potentially mineable ore deposit. It is commonly expressed as a percentage (%), parts per million (ppm) or grams per ton (g/t). For example, a gold grade of 0.27 g/t indicates that for each ton of ore, it is possible to find 0.27 grams of this metal.

Mineral material deposited in rock fissures, cracks or crevices, whose composition is different from the substance in which it is embedded.

Deposit, ore, rock or mineral in which several metals proliferate and coexist.

Low mineral deposit, characterized by the disseminated occurrence of mineral within a large volume of igneous rock with porphyry texture.

Metals with a high economic value due to factors such as their scarcity, use in industrial processes and their role throughout history as a store value assets. Chemically, precious metals tend to be less reactive than most elements, and they are usually ductile and lustrous.

Solid material derived from a liquid solution by means of precipitation.
