List of gold mining disasters

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.

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]
