We aim to conduct our business with integrity based on Guinea Alumina Corporation’s values and applicable laws. Working with integrity allows us to meet the high expectations of our shareholders, customers, business partners and communities.

Our Code of Conduct details our expectations for how everyone at GAC – including directors, employees, contract workers and consultants working with or on behalf of GAC – should behave. See insert on this page to download GAC’s Code of Conduct.

GAC has an independently-operated system to ensure anyone may anonymously and confidentially report any concern related to integrity. This system is called: “Your Voice”. It is available 24/7 and in multiple languages by toll free telephone, online and through letter boxes at our sites.

Concerns can be reported by email to  or by telephone within the company on extension 8123.

We expect that our suppliers, contractors and business partners adopt the same high standards and principles through adhering to our Supplier Declaration, which you can download from the insert on this page.

GAC also operates a zero-cash policy for payments. We require all transactions to be carried out by bank transfer or cheque, to ensure traceability and recording.

On 9 December each year, GAC marks International Anti-Corruption Day to further sensitise employees to the risks related to corruption, and to reinforce our corporate commitment to combat this scourge.
