Environmental, Social and Governance financial

"progress and achievements across a range of Environmental, Social and Governance ("ESG") practices"

Environmental, social and governance (ESG) describes how a company manages its impact on the planet, how it treats people and how it is governed. Investors treat ESG like a report card—companies that score well tend to face fewer regulatory, legal and reputational surprises, attract customers and employees more easily, and may deliver steadier long‑term returns, while poor ESG performance can signal added risk to investment value.

2030 HSEC Strategy financial

"We continued to advance our 2030 HSEC Strategy, which provides the framework for embedding responsible mining practices"

Global Reporting Initiative (GRI) financial

"The Report is guided by internationally recognized reporting standards and frameworks, including the Global Reporting Initiative (GRI)"

A widely used set of guidelines for how organizations report their environmental, social and governance performance, the Global Reporting Initiative (GRI) gives a common “recipe” for describing impacts such as emissions, labor practices and community relations. For investors it matters because consistent, comparable reporting makes it easier to assess long-term risks and opportunities that aren’t visible in financial statements alone — like pollution liability, supply-chain problems, or reputation exposure.

Sustainability Accounting Standards Board (SASB) financial

"guided by internationally recognized reporting standards and frameworks, including the Global Reporting Initiative (GRI), the Sustainability Accounting Standards Board (SASB)"

A sustainability accounting standards board (SASB) develops industry-specific standards that tell companies which environmental, social, and governance issues are likely to affect financial performance and should be disclosed to investors. Think of it as a checklist that makes sustainability information consistent and comparable across companies, helping investors judge risks and opportunities—like assessing how well different cars score on fuel efficiency when deciding which to buy.

Task Force on Climate-related Financial Disclosures (TCFD) financial

"and the Task Force on Climate-related Financial Disclosures (TCFD)"

A set of recommended disclosures on how climate change creates financial risks and opportunities for a company, covering governance, strategy, risk management and metrics. Think of it like a standardized inspection report that helps investors compare how well different companies identify and prepare for climate-related threats and chances; clearer, consistent reporting makes it easier to assess long-term risk, value and where to put capital.

accountable mining financial

"committed to maintaining its culture of accountable mining through high standards of Environmental, Social and Governance practices"
