As a member of the World Gold Council, Alamos is a proud supporter of the Responsible Gold Mining Principles. The ten Principles provide a framework that sets clear expectations for consumers, investors, and the downstream gold supply chain as to what constitutes responsible gold mining, addressing key environmental, social and governance issues for the gold mining sector. They are designed to provide confidence to governments, investors, employees and contractors, communities, supply chain partners and civil society that gold has been produced responsibly. Following the release of the Principles in September 2019, Alamos has been implementing the framework and receives annual independent assurance over its ongoing conformance to the Principles. We do this to provide further confidence that the gold we produce is responsibly mined. Copies of our annual Responsible Gold Mining Principles Reports (RGMP Reports) are available here.

Sustainability Reports

The Alamos ESG Report is an annual publication outlining the Company’s performance across our operating mines and development projects. The report is published voluntarily by Alamos and includes sustainability performance data and metrics collected on an annual basis and prepared using the Global Reporting Initiative’s GRI Standards and the Sustainability Accounting Standards Board’s Metals & Mining Standard.

    ESG Summary Tables and Interactive Database

    Alamos ESG Summary Tables provide an overview of Alamos Gold’s environmental, social and governance (ESG) performance for the calendar year. These tables are prepared in response to investor and lender requests for consolidated annual ESG performance information.

      Conflict Free Gold Report

      The Conflict-Free Gold Standard provides a mechanism by which gold producers can assess and provide assurance that their gold has been extracted in a manner that does not cause, support or benefit unlawful armed conflict or contribute to serious human rights abuses or breaches of international humanitarian law.

      The following reports summarize Alamos’ conformance to the requirements of the Standard which was subject to independent assurance.

        ESTMA Report

        On June 1, 2015, the Extractive Sector Transparency Measures Act (ESTMA) was enacted to contribute to the global efforts of increasing transparency and deterring corruption. ESTMA requires extractive entities to report specific payments made to governments in Canada and abroad related to the commercial development of oil, natural gas or minerals. Alamos annually discloses these payments made on a country and project basis in our ESTMA report.

          RGMP Report

          In September 2019, the World Gold Council published the Responsible Gold Mining Principles. The Principles were developed for investors, supply chain participants, communities, and governments to demonstrate that gold can be responsibly sourced and produced to the highest ethical, governance, social, safety and environmental standards. Implementing companies are required to annually report on their progress towards achieving conformance and obtain independent assurance.
