Biodiversity offsets Conservation actions intended to compensate for the residual, unavoidable harm to biodiversity caused by development projects, so as to ensure no net loss of biodiversity. Block model A three-dimensional model of the distribution of ore and waste materials with different geochemical properties (metalliferous mines). Bund An earthen retaining wall. A low embankment often constructed around potential spillage areas to reduce the risk of environmental contamination. It is important these structures can retain the volume of any potential spillage. Capillary break A layer of coarse material placed with a limited capillary rise between finer-textured materials to prevent the vertical movement of water (and associated salts) by surface tension from the lower, finer-textured material into the upper finer-textured material. Care and maintenance (temporary closure) Phase following temporary cessation of operations when infrastructure remains intact and the site continues to be managed. Cemented paste tailings Tailings with the consistency of a paste, to which cement is added to enhance strength for underground stope backfill. Centreline method, construction or raising Construction of the tailings containment walls above a fixed crest alignment, using waste rock, borrow materials or tailings. Central thickened discharge The discharge of thickened tailings from one or more towers or discharges located within the body of the facility, with only a nominal perimeter wall where any supernatant water is recovered. Centrifuge A device that dewaters a slurry through the application of centrifugal force against a drainage surface. CIL Carbon-in-leach. A process used to recover gold into activated carbon during the agitation leach process. CIP Carbon-in-pulp. A similar metallurgical process to CIL used to recover gold. Cleaner Production The continuous application of an integrated preventive environmental strategy to processes, products, and services in ways that increase efficiency and reduce risks to humans and the environment. By reducing pollution and waste at the source, and striving for continuous improvement, cleaner production can bring financial as well as environmental benefits.

Closure A whole of mine life process which typically culminates in tenement relinquishment. It includes decommissioning and rehabilitation. Coarse (coal) reject The coarse fraction of the mineral matter removed from run-of-mine coal by washing. Co-disposal The combined disposal of coarse and fine-grained mine wastes, such as the pumped codisposal of coal washery wastes. Community There are many ways to define ‘community’. In mining industry terms, community is generally applied to the inhabitants of immediate and surrounding areas who are affected by a company’s activities. ‘Local community’ usually indicates a community in which operations are located and may include Indigenous and non-Indigenous people. Community engagement Deliberate and strategic liaison with communities and individuals that reside in close proximity to, and are potentially affected by, mining activity. Effective engagement typically involves identifying and prioritising stakeholders, conducting dialogue to understand their interest in a an issue and any concerns they may have, exploring with them ways to address these issues, and providing feedback on actions taken. Community impact Detrimental harm to the neighbouring community. Completion criteria An agreed standard or level of performance which demonstrates successful closure of the site. Consolidation The expulsion of water from settled slurry. Consultation The act of providing information or advice on, and seeking responses to, an actual or proposed event, activity or process. Containment wall A structure providing outer encapsulation for tailings. Contaminated site A site at which hazardous substances occur at concentrations above background levels and where assessment shows it poses, or is likely to pose, an immediate or long-term hazard to human health or the environment. Country When used in the context ‘living on country‘ or ‘speaking for country’ refers to the area of Australia that a particular person or group of Indigenous people have a traditional connection and a sense of belonging to. 184 LEADING PRACTICE SUSTAINABLE DEVELOPMENT PROGRAM FOR THE MINING INDUSTRY
