Solid-state process where minerals regrow due to heat and pressure, forming new textures.

Reduction of stresses in rock mass after excavation, influencing deformation and stability.

Acquisition of geospatial data using satellites or aircraft for mapping, alteration detection and exploration.

Categorisation of mineral resources into inferred, indicated and measured based on geological confidence (CRIRSCO).

Airborne particles small enough (

Mining method where pillars or support structures are mined in retreat, allowing controlled collapse. Used in coal and room-and-pillar mines.

Drilling technique where cuttings are returned up the inner tube with compressed air, producing clean samples for geochemistry.

Material originally classified as waste or low grade that becomes economic due to price increases or technology improvements.

Financing mechanism where funds are continually replenished through repayments or revenue cycles, often used in development projects.

Change of land-use designation (e.g., from agricultural to industrial/mining), affecting permitting and development.

Study of flow properties of slurries and tailings, critical for pumping, thickening and pipeline transport.

Elevated linear landform formed by resistant rock units or tectonic uplift. Useful for mapping and structural interpretation.
