The percentage of waste incorporated into ore during mining. Used in reserve estimation and mine planning.

The collection of mobile equipment used in mining, including trucks, loaders, shovels, drills and dozers.

Application of geology to mining operations to optimise ore extraction, grade control and reconciliation.

Legal tenure granting rights to extract minerals within a defined area, subject to regulation and royalties.

The chosen approach to extract an orebody (open pit, underground, block caving, longwall, etc.) based on geometry, grade and economics.

The blend of ore types or grades sent to processing to optimise recovery and plant performance.

A numerical model integrating geology, engineering and production parameters to simulate mining operations and forecast outputs.

Chemical reagents used in mineral processing (collectors, frothers, depressants, flocculants). Influence flotation performance, recovery and selectivity.

Percentage of ore extracted relative to the total mineable resource. Losses occur due to geometry, dilution or mining constraints.

Legal right granted by government authorities allowing exploration or extraction of minerals within a defined area.

Planned order in which ore zones are mined to optimise grade, cashflow, safety and geotechnical stability.

Specialised software such as Whittle, Surpac, Datamine, Vulcan or Deswik used for modelling, mine design, scheduling and optimisation.
