MiningWatch Canada prepared this brief for Access Facility's expert meeting on practical solutions to the implementation of the UN Guiding Principles on Business and Human Rights' “effectiveness criteria.” The data for this brief is derived from the work of MiningWatch Canada and our local and international partners on a project-level non-judicial grievance mechanism at Barrick’s Porgera Joint Venture mine in Papua New Guinea, as well as our initial engagement on a similar mechanism at African Barrick Gold’s North Mara mine in Tanzania.
