What this topic covers
Prevention, detection, remediation and provisioning for unintended releases of cyanide, acids, flotation reagents, hydrocarbons, heavy metals, saline water, radioactive particles, seepage and acid or metalliferous drainage to soil, groundwater and surface water.
How it shows up in this industry
Precious metal, rare earth and specialty mineral operations use cyanide, lime, caustic soda, hydrochloric acid, sulphuric acid, nitric acid, flotation reagents, activated carbon, fuels and lubricants. Heap leach pads, reagent tanks, fuel farms, laboratories, exposed sulphide waste, historical workings and closed facilities can create seepage, acid rock drainage, legacy contamination, open shafts and long-term treatment obligations.
Why it may be material
Uncontrolled releases create remediation liabilities, regulatory orders, fines, litigation, higher closure provisions and production restrictions. They can also undermine land access agreements, refinancing, asset transactions and future permitting for expansions or new deposits.
Impact pathway
- Potential effects may reach soil and groundwater.
- Potential effects may reach water bodies.
- Potential effects may reach ecosystems.
- Potential effects may reach affected communities.
- Potential effects may reach workers.
- Potential effects may reach future generations.
- Affected stakeholder groups identified in the source include Affected communities, Contractors, Employees.
- The source places the pathway in Own operations, Downstream.
Financial pathway
- The topic may change operating costs through resource use, controls, remediation or ongoing management.
- The topic may require capital expenditure to adapt assets, processes or infrastructure.
- The topic may create provisions, penalties, remediation costs, claims or other liabilities.
- The topic may affect access to finance, funding terms or the cost of capital.
- The topic may affect insurance availability, coverage terms, premiums or claims.
- The topic may affect asset useful lives, impairment assumptions, valuations or stranded-asset exposure.
- The topic may affect reputation, licences to operate, intellectual property or other intangible value.
Questions to test
- What evidence supports both the impact and financial materiality pathways?
- Which own operations, assets or decisions create or concentrate the pathway?
- Which products, services, customers or end uses create or concentrate the pathway?
- What is the scale, scope, likelihood and remediability of effects on soil and groundwater?
- What is the scale, scope, likelihood and remediability of effects on water bodies?
- What current or proposed regulation could change the topic's relevance?

It may be less material when…
- Organisation-specific evidence does not support significant scale, severity, likelihood or financial effect.
- The organisation has no meaningful exposure to or influence over the relevant downstream pathway.
