Artisanal and Small-Scale Mining (ASM): Artisanal mining may involve individuals or families using pre-industrial techniques, compared to small-scale mining, which may be more extensive and more mechanized. However, both are labour intensive, explore small or marginal deposits, and are characterized by poor access to markets, lack of standards for health and safety, and low capital input. ASM, which ranges from informal subsistence mining by individuals to small formal commercial mining operations, can provide a key source of income in many communities.

Biodiversity: An abbreviation of biological diversity, biodiversity refers to the variety of life on earth: the different animals, plants and micro-organisms, and the ecosystems of which they are a part.

Cap and Trade System: A mechanism designed to limit and reduce greenhouse gas (GHG) emissions by setting a decreasing limit on their emissions (the cap) and by allowing entities within the system to trade their excess/debt to meet the overall reduction target.

Events are considered as ‘incidents’ only to the extent that they arise from company activities, with the implication that there is some ability to exert control over circumstances prior to the event.

Indigenous Peoples: Cultural groups and their descendants who have a historical association with, and continuity in, a particular region or part of a region. They have a cultural identity and, as minorities, they may be vulnerable to current social and economic systems. Indigenous Peoples is the globally used term and Aboriginal Peoples is the term used in Canada. There are three Aboriginal groups in Canada: First Nations, Inuit and Métis.

Saturated Rock Fill (SRF): SRFs use naturally-occurring biological processes in former mining areas that have been backfilled with rock and saturated with water to remove selenium and nitrate. First, water for treatment is injected into the SRF and then natural bacteria convert dissolved forms of selenium into a solid form, which remains securely stored in the SRF and nitrate to inert nitrogen gas that is safely released.

Scope 1 (Direct) Greenhouse Gas Emissions: Emissions that occur from energy sources that are owned or controlled by the company.

Scope 2 (Indirect) Greenhouse Gas Emissions: Emissions that occur from the generation of purchased electricity consumed by the company. Scope 2 emissions physically occur at the facility where electricity is generated.

Scope 3 (Other Indirect) Greenhouse Gas Emissions: Other indirect emissions not covered in Scope 1 or 2, such as emissions that arise from sources owned or controlled by other companies within the value chain of a company. For example, emissions arising from business travel by employees, the use of our products, and the transportation of materials that we purchase and sell.

Seawater: Water obtained from a sea or ocean.

Severity: A measure of safety performance that illustrates the number of days lost due to injuries. Severity is a frequency measure based on every 200,000 hours worked and is calculated as follows: (number of days missed due to lost-time injuries x 200,000) divided by actual number of hours worked. A fatality is calculated as 6,000 days lost.

Site: A location under the management control of Teck. For example, these include exploration sites, facilities and operations.

Social and Environmental Impact Assessment (SEIA): An input to decision-making that seeks to evaluate the significant issues associated with a proposed undertaking (e.g., a resource development project) in order to predict and assess its likely positive and negative impacts. Depending on the scope of the SEIA, the examination of issues may extend to cumulative, transboundary or global impacts, as appropriate. Impact assessment typically includes establishing baseline data, analysis of alternatives, and determination of a management program to mitigate predicted impacts.

Social Baseline: A study to understand the current socio-economic or human environment around a proposed project, mine or associated infrastructure.

Supplier: An organization or individual whose primary function is the provision of goods to Teck in accordance with agreed-upon specifications, terms and conditions. (Note: a supplier who in the course of providing goods also provides ancillary services [e.g. delivery of goods] is nevertheless considered a supplier).

Total Recordable Injury Frequency (TRIF): A key measure of safety performance that demonstrates the total number of recordable injuries per 200,000 hours worked. Recordable injuries include fatalities, lost-time injuries and injuries requiring medical aid. The types of incidents not included in the TRIF calculation include first aid injuries, high-potential incidents, non-injury property damage, and non-injury mobile equipment events. TRIF is calculated as follows: TRIF = (number of medical aid injuries + number of lost-time injuries + number of fatal injuries x 200,000) divided by total number of hours worked. The factor of 200,000 is derived from the average number of hours worked by 100 people in a one-year period (50 working weeks x 40 hours per week x 100 people). This factor is frequently used in North America.
