Background
Mimosa coal mines are a group of underground and surface mines in Sabinas, Coahuila, Mexico.[3]
The Mimosa mine complex is one of two large mining operations owned by Mexican steel producer Altos Hornos de México (AHMSA) and operated by AHMSA subsidiary Minera Del Norte (Minosa).[3] Mimosa is Mexico's second leading coal producer, surpassed only by AHMSA's Micare mine.[4][5] The Mimosa complex includes 4 underground mines and 1 open cast mine[6], with the collective capacity to produce approximately 4 million tonnes of metallurgical and thermal coal per year.[3] Met coal from the Mimosa mines is transported via a 130-kilometer rail line to the Altos Hornos de México (AHMSA) steel plant, where it is used for steel production.[6] Thermal coal from the mines has historically been sold to CFE (Mexico's federal electricity commission) for energy production.[7]
In 2022, AHMSA shut down Mimosa's Mine VII, whose met coal reserves had been depleted after 15 years of operations.[8] At the same time, the company announced the startup of Mine VIII, whose 100 million tons of high-quality metallurgical coal reserves were expected to play a key role in AHMSA's steel production over the next 30 years.[8]

Production
Following a steep downturn in 2020 due to the COVID-19 pandemic, production at the Mimosa mines has rebounded. Global Data estimated that the mines produced 2.6 million tonnes of coal in 2021.[4] As of early 2023, the mines were reportedly continuing to produce at close to their annual capacity of 4 million tpa (tonnes per annum), despite the fact that mine operator Minosa had been forced to seek bankruptcy protection following CFE's unilateral cancellation of coal purchase contracts.[9]

| Year | Met Coal Production (Mtpa) | Thermal Coal Production (Mtpa) | Total Production (Mtpa) |
|---|---|---|---|
| 2020 | 0.41[6] | 0.52[6] | 0.93[6] |
| 2019 | 1.22[6] | 1.46[6] | 2.68[6] |
| 2018 | 1.39[6] | 1.76[6] | 3.15[6] |

| 2016 | 1.39[7] | 1.09[7] | 2.48[7] |
Accidents
In 2011 one of the mines (Mina Esmeralda) collapsed, killing 4 miners; 132 miners were working in the mine when the accident occurred.[10]
