Political tension over the discharge of artisanal mine tailings into the Puyango-Tumbes River in Ecuador, which flows into northern Peru, has prompted the closure of the responsible artisanal plants and the construction of central processing and communal tailings faculties. A coordinated effort on behalf of the federal government, miners, and the local community to develop and fund the project and bring it to completion is underway with the goal of eliminating riverine tailings disposal in the area and reclaiming the current artisanal gold processing. The goal of this paper is to explore the closure process developed for the artisanal gold processing plants and their dismantlement and reclamation, and to assess whether the proposed plan will prevent riverine tailings disposal by artisanal mine processing plants.
