List of gold mining disasters
From Wikipedia the free encyclopedia
This is a list of gold mining disasters including environmental, such as those arising due to dam failure, cyanide leakage into the environment, as well as inappropriate environmental toxic waste discharge due to the gold cyanidation technique used in gold mining. Other disasters at gold mines such as those resulting in loss of life are also listed.
| Year | Mine | Location | Majority Owner | Company Location | Details |
|---|---|---|---|---|---|
| 1882 | Creswick |  Australia | New Australasian Gold Mine disaster: Australia's worst below-ground gold mining disaster.[1] | ||
| 1971 | Certej Mine |  Romania | 1971 Certej dam failure: A dam failure resulted in the leak of 300,000 cubic metres of cyanide-contaminated flood Certeju de Sus, resulting in 89 deaths. | ||
| 1984-2013 | Ok Tedi Mine |  Papua New Guinea | Broken Hill Proprietary Co. | Australia | Ok Tedi environmental disaster: Unrestricted waste discharges from the mine had strong effects on the environment and the 50,000 people who live downstream. Over 2 billion tons of untreated mining waste were thus discharged. |
| 1984-2013 | Summitville mine |  USA | Galactic Resources |  Canada | A Canadian-based company used gold cyanidation process to extract gold, resulted in 610,000 m³ of stored toxic water. Following the company's bankruptcy, the US government spent over $155 million to clean the site. |
| 1995 | Omai mine |  Guyana | Omai Gold Mines (subsidiary of Cambior) | Canada | 3 million cubic metres of cyanide-tainted waste was spilled into the Omai river and then the Essequibo river following a dam failure.[2] |
| 1996 | Mt. Tapian |  The Philippines | Marcopper Mining | Canada | Marcopper mining disaster: A fracture of the drainage tunnel for a tailings pit led to discharge of toxic waste into Makulapnit-Boac river system, causing large-scale destruction of crops, burying one village with mud and requiring 20 other villages to be evacuated. |
| 1998 | Kumtor Gold Mine |  Kyrgyzstan | Centerra Gold | Canada | A truck carrying 1,762 kg of sodium cyanide fell into the Barskaun River. An international independent group of experts studied the impact of the accident and concluded that no one was killed or poisoned as a result of the accident.[3] |
| 2000 | Baia Mare | Romania | Esmerelda Exploration Limited | Australia | 2000 Baia Mare cyanide spill: A dam failure resulted in the leak of 100,000 cubic metres of cyanide-contaminated water which spilled into the Someş and Tisza. Pollution flowed into Europe's second largest river, the Danube, and finally into the Black Sea, across six countries. Hungary asserted the spill killed 1,241 tonnes of fish in Hungary alone.[4] |
| 2000 | Tolukuma gold mine | Papua New Guinea | Dome Resources | Australia | A one-tonne cyanide crate fell from a helicopter into the jungle, while heavy rain in the area washed 100–150 kg of it into a river.[5] |
| 2006 | Beaconsfield gold mine | Australia | Beaconsfield Mine collapse: 1 miner was killed and 2 were trapped underground for a fortnight.[6] | ||
| 2009 | Ahafo gold mine |  Ghana | Newmont Mining | USA | Overflow of process solution containing sodium cyanide occurred within the processing plant site at Newmont Ghana's open pit Ahafo Mine. This resulted in water contamination and fish mortality.[7] |
| 5 August 2015 | Gold King Mine | USA | USA | 2015 Gold King Mine waste water spill: In Silverton, Colorado, Environmental Protection Agency (EPA) personnel, along with workers for Environmental Restoration LLC, caused the release of toxic waste water into the Animas River watershed.[8] | |
| 2015 | Veladero mine, San Juan province |  Argentina | Barrick Gold | Canada | 1,072 cubic meters of cyanide solution reached the Potrerillos River due to a valve failure.[9] |
| 2019 | Kampine mine, Kampine town, Maniema |  Democratic Republic of the Congo | 22 illegal miners dead in an illegally run mine.[10] | ||
| 2020 | Kamituga mine, Kamitung town, South Kivu | Democratic Republic of the Congo | 50+ dead due to mine collapse caused by heavy rain. Three tunnels to the mine was blocked because of the heavy flow of water.[11] | ||

| 2024 | Eagle Gold Mine | Canada | Victoria Gold Corp | Canada | On June 24, 2024, 300,000 cubic metres of cyanide-contaminated water leaked from a heap leach failure in Victoria Gold Corp's Eagle Gold Mine site near Mayo, Yukon.
