Background

San Juaquin Mine or San Joaquin Mine is a closed coal mine located in the municipality of Amagá, in southwestern Antioquia, Colombia.[6] The San Juaquin Mine is owned by Carbones San Fernando SAS[6][7][8], which is a subsidiary of Grupo Corporativo Vatia S.A.S (Vatia).[6] Operating since April 2008, it is one of the largest longwall mines in Colombia.[6] The mine's initial production was 80,600 tons per year, but according to the EPA, between 2008 and 2017 the mine "consistently produced approximately 180,000 tons per year" with "an estimated operational life span of over 50 years."[6] A more recent report from 2021 estimated that the mine's average production was 800 tonnes of coal per day.[9]

Accidents and Fatalities

2010 Explosion

73 miners died in an explosion in the San Juaquin Mine in 2010. According to reporters, it was one of the "worst mining accidents in the country." One week prior to the explosion, an engineer had warned that something must be urgently done by Carbones San Fernando SAS to control the high temperatures inside the mine, improve ventilation, lower the dangerous level of methane gas, and manage dust. Reports later found that the dust and gas in the mine made it easier for the fire to spread throughout the mine, killing the miners. The cause of the fire remains unknown.[10][11] The company offered new homes and payments of two million pesos to the miners' widows, in exchange for giving up their claims to any future compensation.[10]

2023 Machinery-Related Fatality

In April 2023, a young man died after injuries incurred in the San Juaquin mine when the man was trapped in mining-related machinery.[12]

Company Financial Difficulties and Change of Ownership

In October 2025, Carbones San Fernando S.A.S. was declared subject to judicial liquidation proceedings by Colombia's Superintendencia de Sociedades, effective October 28, 2025, leaving over 240 workers unemployed. The company had accumulated overdue administrative obligations exceeding COP$4.198 billion (approximately US$976,000). Shortly after, an investor from Boyacá department agreed to take over the mine under a six-month lease with an option to purchase, allowing operations to resume under a new name and operator. Approximately 150 of the 241 displaced workers were expected to be rehired. A decision on whether to proceed with the purchase was expected upon expiry of the lease agreement.[13]
