Through Alcoa’s ownership interest in Halco (Mining) Inc., we are proactively monitoring CBG’s approach to community issues and its response to a complaint filed through the International Finance Corporation’s (IFC) grievance mechanism. The complaint alleges contraventions by CBG of IFC Performance Standards, including in relation to resettlement and environmental impacts. CBG has agreed to participate in a mediation process facilitated by the Compliance Advisor Ombudsman of the IFC. The mediation is currently underway.

As a Halco Shareholder, Alcoa has increased its support to CBG through Halco by providing additional expert help in the form of senior specialist personnel with extensive experience on resettlement and human rights. We welcome the Ground Rules agreement reached by the parties in December 2020, which sets out the principles to be followed by all parties involved in the mediation process.
