On November 4, 2025 a dam at a mine in Lubumbashi broke and released acid-laden water. The mine is run by Congo Dongfang Mining, a subsidiary of Zhejiang Huayou Cobalt Ltd.
Water filled ditches, entered homes and flooded the Moïse Katumbi market. Witnesses say CDM made channels through the southern wall to discharge large amounts of acidic wastewater. Local people say neighborhoods Kasapa, Kamisepe and Kamatete have had floods and house collapses each rainy season since 2012. In 2020 the NGO Afrewatch warned the company and authorities to protect people and the environment.
Authorities visited the site. On November 6, 2025 mining activities were suspended for three months. An investigation was announced on November 22, 2025.
