The active surface where mining extraction is taking place in a pit, stope or coal panel.

Fragment of older rock engulfed by intrusive magma. Useful indicator of magma sources and ore-forming processes.

Analytical method measuring elemental composition by detecting fluorescence emitted after X-ray excitation.

Proportion of metal recovered relative to the theoretical amount present in ore. Influences project economics.

Concentrated zinc sulphide product produced by flotation, containing typically 45–60% Zn.

Normalised grade combining zinc and other payable metals into a single Zn-equivalent grade based on metal prices and recoveries.

Zirconium silicate mineral (ZrSiO₄) used in ceramics and as a geochronological mineral due to U-Pb dating properties.

Metal used in high-temperature alloys, ceramics and nuclear cladding. Often obtained from zircon minerals.

Near-surface region where sulphides alter to oxides due to weathering, often improving leachability.

Deeper zone where oxygen is absent and reducing conditions dominate, preserving sulphides.

Pattern of compositional changes within mineral crystals, indicating growth history and fluid evolution.

Método contable en el que los ingresos y gastos se registran cuando se generan o se incurren, y no cuando se cobra o se paga el efectivo. En una minera esto implica, por ejemplo, capitalizar gastos de exploración o...
